Besides reducing waste and our impact on the environment, it can speed up construction from weeks, or months, to days. To see how the technology can change the world around us, here are some projects that highlight bold ideas in 3D print building. Instant Neighborhood Community building takes on new meaning with the creation of a neighborhood of 3D printed homes in Tabasco, Mexico, aimed at tackling global homelessness. American non-profit New Story and tech company ICON built each concrete house from start to completion in 24 hours. New Story says its aim is to provide shelter for people without homes around the world. Nested Housing Shamballa is the idea of Italian 3D print construction company WASP. This project uses soil and straw to build a home in days that cost only 48 Euros in materials and energy. Its round designs are based on the wasp(黄蜂)nest. Each home features a laboratory with a desktop 3D printer for making furniture, artistic objects and more. Think Schools African island state Madagascar is hosting one of the world’s most forward-thinking school building projects. Non-profit Thinking Huts is using 3D print technology to provide schools where children have little or no access to education. Schools are built using local materials and low carbon concrete in under a week. Concrete Steps Researchers at the Swiss University ETH Zurich used concrete 3D printing to build the 16 metre long curved Striatus footbridge in a couple of days. The project used500 layers of concrete and53 hollow blocks, held in place by compression(压缩). This reduces materials by up to 70 percent, and the entire bridge can be pulled down and recycled. 21．What could be the inspiration behind the design of Nested Housing? A．A featured laboratory. B．A forward-thinking school C．A round wasp nest. D．A long stone bridge. 22．Which 3D construction project can be torn down and reused? A．Instant Neighborhood. B．Concrete Steps. C．Think School. D．Nested Housing. 23．What do these four 3D building projects have in common? A．They use local materials. B．They are affordable to the homeless C．They are high in cost. D．They make construction faster. B I remember doing the household chores to help my mother when I was nine. I hated changing the vacuum cleaner (真空吸尘器) bag and picking up things the machine did not clean away. Twenty years later, in 1978, with this lifelong dislike of the way the machine worked, I decided to make a bagless one. Easier said than done, of course. I didn’t realize that I would spend the next five years perfecting my design, a process that resulted in 5,127 different prototypes (样机). By the time I made my 15th prototype, my third child was born. By 2,627, my wife and I were really counting our pennies (便士). By 3,727, my wife was giving art lessons for some extra cash, and we were getting further and further into debt. These were tough times, but each failure brought me closer to solving the problem. In the early 1980s, I started trying to get licensing agreements for my technology. The reality was very different, however. The major vacuum makers had built a business model based on the profits from bags and filters (滤网). No one would license my idea, not because it was a bad one, but because it was bad for business. But soon after, the companies that I had talked with started making machines like mine. I had to fight legal battles on both sides of the Atlantic to protect the patents on my vacuum cleaner. I was still in financial difficulties until 1993, when my bank manager personally persuaded Lloyds Bank to lend me $1 million. Then I was able to go into production. Within two years, the Dyson vacuum cleaner became a best-seller in Britain. Today, I still accept risk and the potential for failure as part of the process. Nothing beats the excitement of invention. 24．What drove the author to make a bagless vacuum cleaner? A．His willingness to help mom. B．His curiosity about machines. C．His trouble in doing family chores. D．His discontent with existing cleaners. 25．What does paragraph 2 mainly tell us? A．The help from the author’s wife. B．The financial problems of the family. C．The tough process of the new invention. D．The procedures of making a bagless cleaner. 26．Why did the companies refuse to license the author’s technology? A．They thought they might suffer loss. B．They considered it not good enough. C．They faced legal problems themselves. D．They had begun making such machines. 27．What lesson may the author learn from the experience? A．Think twice before acting. B．Failure is the mother of success. C．Actions speak louder than words. D．A good beginning makes a good ending. C Rosie, a three-year-old black Labrador dog, can do something no person in the world is able to do. She smells four containers of urine (尿液) samples and correctly chooses the one that belongs to a National Health Service patient with bladder (膀胱) cancer. To show it is not just by accident, Rosie’s trainers keep changing the order of the containers. Again and again, the dog finds the cancer sample correctly. Scientists believe this ability could be the beginning of a major change in how we detect cancer. But it has been difficult for researchers to find a way to use this on a large scale in real-world medical settings. It would simply not be practical for the health service to let a group of dogs smell patients in busy hospital waiting rooms. Now, however, technology has offered an answer. Dr Andreas Mershin, a researcher at the Massachusetts Institute of Technology, has worked with the organization Medical Detection Dogs to create an electronic nose, or “e-nose”. This device was developed by training artificial intelligence to copy the way dogs react to the smelly chemicals found in urine. Once the machine learns this, it can also “smell” urine samples by detecting those same tiny chemicals in the air. The e-nose is now being tested on more than 500 urine samples from patients at Milton Keynes University Hospital, to see if it is as accurate as the dogs. Dr Mershin hopes it can be approved as a medical tool in hospitals within two years. He also said the technology could one day even be built into smartphones. The team of scientists and dog trainers works closely with local doctors, who are very hopeful about what the e-nose could achieve. They believe it could lead to tests that do not require any cutting or entering the body. Such tests would be especially important for illnesses where people often delay getting checked because they feel embarrassed, waiting until they experience troubling symptoms. 28．What is the limitation of using dogs for cancer detection? A．They are not accurate enough. B．They are hard to use widely. C．They are too expensive to train. D．They are too difficult to control. 29．What can we infer about the e-nose? A．It may be used in phones. B．It has been applied in treatment. C．It works better than trained dogs. D．It can only detect chemicals in urine. 30．What will be possibly discussed in the following paragraph? A．Methods of keeping healthy. B．Better ways to train Rosie. C．Causes of bladder cancer. D．Further device tests. 31．What can be a suitable title for the text? A．New Ways to Train Working Dogs. B．Dogs with Special Smelling Skills. C．An AI Device for Cancer Detection. D．Traditional Tools for Bladder Cancer. D You, along with all living things, produce weak light that glows (发出微弱稳定的光) until you die, according to a recent study. It’s called ultraweak photon emission (UPE) and is a natural product of your metabolism (新陈代谢). UPE is produced when chemicals in your cells create unstable molecules (分子) known as reactive oxygen species (ROS) as by-products of your body’s metabolism. When ROS levels rise, they cause other molecules to become “excited”, meaning they carry excess (额外的) energy. It’s this energy that causes light to be released. “I normally point out that UPE is a result of a biochemical process and in that sense is related to what happens in a glow-stick,” Dr Daniel Oblak, a physicist at the University of Calgary and last author of the study, said. “UPE is so weak that it is not visible to the human eye and completely overwhelmed by other sources of light, unless you are in a completely dark room.” That’s not to say that shutting your curtains and turning off your lights will allow you to see your own glow. This light is between 1,000 and 1,000,000 times weaker than the human eye can perceive. Using specialist cameras, scientists observed much more UPE being released by the living mice, compared to their dead bodies. Meanwhile, the leaves gave off much more light where they had been damaged, compared to undamaged areas. That’s because they were experiencing more oxidative (氧化的) stress in damaged regions. But the dead mice did not glow, because their bodies weren’t metabolising anymore. Oblak said that the key advantage of UPE is that it offers a non-invasive method of observing the health of living things. “This could be used to track the condition of a tissue — for example, for use in transplants — or the level of stress an organism is subject to, such as for monitoring crop or forest health,” he said. But this field is still full of unknowns. For instance, Oblak said, “Perhaps UPE is not just a byproduct of metabolic processes, but also serves a purpose.” Scientists just aren’t sure yet. 32．What causes ultraweak photon emission? A．Direct exposure to bright light in a dark room. B．The presence of reactive oxygen species in cells. C．The use of specialized cameras on dead organisms. D．The human eye’s ability to perceive dim light. 33．What can be learned about UPE from the text? A．It is visible to the human eye without equipment. B．It is a supernatural phenomenon. C．It is generated through a biochemical process. D．It is only produced by damaged tissues. 34．Why did the injured leaves give off more light than undamaged areas? A．They were suffering more oxidative stress. B．They were no longer metabolizing. C．They produced more reactive oxygen species after death. D．They were placed in a completely dark room. 35．What is the author’s purpose in writing the text? A．To explain why dead organisms stop glowing. B．To compare UPE in mice and plants. C．To argue that UPE is a purposeful biological signal. D．To introduce UPE and its potential applications. 第二节（共5小题：每小题2. 5分, 满分12. 5分） 阅读下面短文, 从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 Cloud storage is a flexible and convenient way to store data with complete peace of mind. 36 This means you can store all your digital things remotely, without taking up space on your computer. There are two options available: public cloud storage allows you to share hosting space with other users; private cloud storage is the ideal choice for companies who want to have their data stored in their own environment. 37 Once you have registered and set up your account, you simply save your files via the internet using your username and password. This ensures your data remains secure and inaccessible to anyone else. Should you choose, you can put certain permissions in place, which makes it easy to share your data with your colleagues or your family. When you sign up to cloud storage, you can choose the amount of space you need. 38 You can store anything digital: all your files, videos and pictures. Whether you want to use this storage solution to store your family photographs or you want to use it to store your work documentation, you will find it quite convenient. Is it better than your computer or an external drive? The answer is a definite yes. Computers crash all the time. 39 External hard drives can still break, or fail. Here you also have the added risk of misplacing it or having it stolen. There are so many advantages to cloud computing, from the ability to access your data from wherever, whenever, to not needing expensive external storage devices. 40 A．You will find cloud storage very cheap. B．Cloud storage is very simple to use. C．It enables you to store your data on hosted servers. D．This is the most common cause of lost work and memories. E．Cloud storage providers offer multiple layers of data security. F．The only disadvantage, however, is that you need internet to access files. G．You can start with a small amount and increase the storage size later on. 第三部分 语言运用（共两节，满分30分） 第一节（共15小题：每小题1分，满分15分） 阅读下面短文, 从每题所给的A、B、C、D四个选项中选出可以填入空白处的最佳选项。 Beckett Zahedi and Derrick Webster Jr. have created a website called Realer Estate. It is a platform 41 to help renters more easily find proper and rent-stabilized apartments in a city where affordable housing costs are often out of 42 . Their goal is simple but powerful — make hard-to-find housing options more 43 to everyday New Yorkers. The project has become an all-consuming 44 for the teens.

Realer Estate brings together public data and real estate (房地产) listings, allowing users to quickly 47 rent-stabilized apartments and units 48 below market value. What is typically a confusing and 49 process for renters is streamlined into one easy-to-use platform. The idea for Realer Estate grew from Zahedi’s personal 50 . He said that seeing how 51 it was to find an affordable apartment after his father got unemployed opened his eyes to how serious the housing crisis is. That understanding 52 in an 11th-grade economics class, where both teens learned more about the scale of the problem. While they 53 their site is just a small step toward solving a much larger issue, the teens remain focused on making a real 54 .

I spent the whole summer with my face in the screen. I didn’t pay attention to my family or the things around me. Being online was more important than being with people. So, you can guess how unhappy I was when I learned what my dad planned for our family vacation that year. “This year, ” my dad said, “we’re going to do something special. We’re going camping!” It was not my dream vacation because I was still thinking about my phone. In fact, I was so busy looking at my phone that I didn’t look up until we drove across a bridge to the campsite. I looked out of the window and saw tall redwood trees. Their branches (树枝) seemed to touch the sky. I saw a river, with dark water showing between the white rapids (激流). The air from the open windows was hot. But none of that caught my eye. The reason I looked up was much more serious: my phone had no service (网络信号). The last hour in the car was hard. My dad said he had chosen a campsite with no cell service, and my phone would be useless until we got home. I would be stuck in the forest for four days with no way to reach the outside world! On the first day, I went through every teenage feeling: I was angry, I asked for help, and I kept going between sadness and anger. I went to bed angrily that night. But when I woke up in the morning, something had changed. 注意：1. 续写词数应为150个左右，可参考文中加粗词汇部分； 2. 请按如下格式在答题卡的相应位置作答。 I stopped looking at my phone and started looking around me. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ The next days went by fast because we did many fun things. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 原创精品资源学科网独家享有版权，侵权必究！1 学科网（北京）股份有限公司1 / 23 学科网（北京）股份有限公司 $听力考试正式开始。Have you used high talk?

In fact, the first man made plastic was made over a hundred years ago. IT was discovered both by englishman and an american in the same year. But IT was the american who first developed on a large scale during the eighteen sixties. Everybody was excited by this new material because I was so cheap. Poor workers were able to buy plastic collars. These plastic collars were hard and uncomfortable, but they were easy to wash. The poor workers could clean them every evening with just soap and water. Poor mothers who had not been able to afford the toys for their children. We're now able to buy inexpensive ones made of plastic. However, plastic has one serious fault. Some kinds of plastic can catch fire very easily. And when they do, a poisonous gas is produced. What's worse, plastic takes a very long time to break down, so that causes serious pollution. We now use the term of White pollution to refer to plastic pollution. The history of plastic is no longer than you might expect. In fact, the first man made plastic was made over a hundred years ago. IT was discovered both by englishman and an american in the same year, but IT was the american who first developed on a large scale during the eighteen sixties. Everybody was excited by this new material because I was so cheap. Poor workers were able to buy plastic collars. These plastic collars were hard and uncomfortable, but they were easy to wash. The poor workers could clean them every evening with just soap and water. Poor mothers who had not been able to afford the toys for their children, we're now able to buy inexpensive ones made of plastic. However, plastic has one serious fault. Some kinds of plastic can catch fire very easily. And when they do how poisonous gas is produced, what's worse, plastic takes a very long time to break down, so that causes serious pollution. We now use the term White pollution to refer the plastic pollution. 听力部分到此结束。 ………………○………………外………………○………………装………………○………………订………………○………………线………………○……………… ………………○………………内………………○………………装………………○………………订………………○………………线………………○……………… 此卷只装订不密封 ………………○………………内………………○………………装………………○………………订………………○………………线………………○……………… ………………○………………外………………○………………装………………○………………订………………○………………线………………○……………… … 学校：______________姓名：_____________班级：_______________考号：______________________ 2026-2027学年高二选择性必修第二册英语单元自测 Unit 4 Living with Technology·基础通关 学校:___________班级：___________姓名：___________分数：___________ （时间：120分钟，满分：150分） 注意事项： 1. 答卷前，考生务必将自己的姓名、准考证号填写在答题卡上。 2. 回答选择题时，选出每小题答案后，用铅笔把答题卡上对应题目的答案标号涂黑。如需改动，用橡皮擦干净后，再选涂其他答案标号。回答非选择题时，将答案写在答题卡上，写在本试卷上无效。 3. 考试结束后，将本试卷和答题卡一并交回。 第一部分 听力（共两节，满分 30 分） 做题时，请先将答案标在试卷上。录音内容结束后，你将有两分钟的时间将试卷上的答案转涂到答题卡上。 第一节（共5小题；每小题1.5分，满分7.5分） 听下面5段对话。每段对话后有一个小题，从题中所给的A、B、C三个选项中选出最佳选项。听完每段对话后，你都有10秒钟的时间来回答有关小题和阅读下一小题。每段对话仅读一遍。 1．What are the speakers talking about?

Besides reducing waste and our impact on the environment, it can speed up construction from weeks, or months, to days. To see how the technology can change the world around us, here are some projects that highlight bold ideas in 3D print building. Instant Neighborhood Community building takes on new meaning with the creation of a neighborhood of 3D printed homes in Tabasco, Mexico, aimed at tackling global homelessness. American non-profit New Story and tech company ICON built each concrete house from start to completion in 24 hours. New Story says its aim is to provide shelter for people without homes around the world. Nested Housing Shamballa is the idea of Italian 3D print construction company WASP. This project uses soil and straw to build a home in days that cost only 48 Euros in materials and energy. Its round designs are based on the wasp(黄蜂)nest. Each home features a laboratory with a desktop 3D printer for making furniture, artistic objects and more. Think Schools African island state Madagascar is hosting one of the world’s most forward-thinking school building projects. Non-profit Thinking Huts is using 3D print technology to provide schools where children have little or no access to education. Schools are built using local materials and low carbon concrete in under a week. Concrete Steps Researchers at the Swiss University ETH Zurich used concrete 3D printing to build the 16 metre long curved Striatus footbridge in a couple of days. The project used500 layers of concrete and53 hollow blocks, held in place by compression(压缩). This reduces materials by up to 70 percent, and the entire bridge can be pulled down and recycled. 21．What could be the inspiration behind the design of Nested Housing? A．A featured laboratory. B．A forward-thinking school C．A round wasp nest. D．A long stone bridge. 22．Which 3D construction project can be torn down and reused? A．Instant Neighborhood. B．Concrete Steps. C．Think School. D．Nested Housing. 23．What do these four 3D building projects have in common? A．They use local materials. B．They are affordable to the homeless C．They are high in cost. D．They make construction faster. B I remember doing the household chores to help my mother when I was nine. I hated changing the vacuum cleaner (真空吸尘器) bag and picking up things the machine did not clean away. Twenty years later, in 1978, with this lifelong dislike of the way the machine worked, I decided to make a bagless one. Easier said than done, of course. I didn’t realize that I would spend the next five years perfecting my design, a process that resulted in 5,127 different prototypes (样机). By the time I made my 15th prototype, my third child was born. By 2,627, my wife and I were really counting our pennies (便士). By 3,727, my wife was giving art lessons for some extra cash, and we were getting further and further into debt. These were tough times, but each failure brought me closer to solving the problem. In the early 1980s, I started trying to get licensing agreements for my technology. The reality was very different, however. The major vacuum makers had built a business model based on the profits from bags and filters (滤网). No one would license my idea, not because it was a bad one, but because it was bad for business. But soon after, the companies that I had talked with started making machines like mine. I had to fight legal battles on both sides of the Atlantic to protect the patents on my vacuum cleaner. I was still in financial difficulties until 1993, when my bank manager personally persuaded Lloyds Bank to lend me $1 million. Then I was able to go into production. Within two years, the Dyson vacuum cleaner became a best-seller in Britain. Today, I still accept risk and the potential for failure as part of the process. Nothing beats the excitement of invention. 24．What drove the author to make a bagless vacuum cleaner? A．His willingness to help mom. B．His curiosity about machines. C．His trouble in doing family chores. D．His discontent with existing cleaners. 25．What does paragraph 2 mainly tell us? A．The help from the author’s wife. B．The financial problems of the family. C．The tough process of the new invention. D．The procedures of making a bagless cleaner. 26．Why did the companies refuse to license the author’s technology? A．They thought they might suffer loss. B．They considered it not good enough. C．They faced legal problems themselves. D．They had begun making such machines. 27．What lesson may the author learn from the experience? A．Think twice before acting. B．Failure is the mother of success. C．Actions speak louder than words. D．A good beginning makes a good ending. C Rosie, a three-year-old black Labrador dog, can do something no person in the world is able to do. She smells four containers of urine (尿液) samples and correctly chooses the one that belongs to a National Health Service patient with bladder (膀胱) cancer. To show it is not just by accident, Rosie’s trainers keep changing the order of the containers. Again and again, the dog finds the cancer sample correctly. Scientists believe this ability could be the beginning of a major change in how we detect cancer. But it has been difficult for researchers to find a way to use this on a large scale in real-world medical settings. It would simply not be practical for the health service to let a group of dogs smell patients in busy hospital waiting rooms. Now, however, technology has offered an answer. Dr Andreas Mershin, a researcher at the Massachusetts Institute of Technology, has worked with the organization Medical Detection Dogs to create an electronic nose, or “e-nose”. This device was developed by training artificial intelligence to copy the way dogs react to the smelly chemicals found in urine. Once the machine learns this, it can also “smell” urine samples by detecting those same tiny chemicals in the air. The e-nose is now being tested on more than 500 urine samples from patients at Milton Keynes University Hospital, to see if it is as accurate as the dogs. Dr Mershin hopes it can be approved as a medical tool in hospitals within two years. He also said the technology could one day even be built into smartphones. The team of scientists and dog trainers works closely with local doctors, who are very hopeful about what the e-nose could achieve. They believe it could lead to tests that do not require any cutting or entering the body. Such tests would be especially important for illnesses where people often delay getting checked because they feel embarrassed, waiting until they experience troubling symptoms. 28．What is the limitation of using dogs for cancer detection? A．They are not accurate enough. B．They are hard to use widely. C．They are too expensive to train. D．They are too difficult to control. 29．What can we infer about the e-nose? A．It may be used in phones. B．It has been applied in treatment. C．It works better than trained dogs. D．It can only detect chemicals in urine. 30．What will be possibly discussed in the following paragraph? A．Methods of keeping healthy. B．Better ways to train Rosie. C．Causes of bladder cancer. D．Further device tests. 31．What can be a suitable title for the text? A．New Ways to Train Working Dogs. B．Dogs with Special Smelling Skills. C．An AI Device for Cancer Detection. D．Traditional Tools for Bladder Cancer. D You, along with all living things, produce weak light that glows (发出微弱稳定的光) until you die, according to a recent study. It’s called ultraweak photon emission (UPE) and is a natural product of your metabolism (新陈代谢). UPE is produced when chemicals in your cells create unstable molecules (分子) known as reactive oxygen species (ROS) as by-products of your body’s metabolism. When ROS levels rise, they cause other molecules to become “excited”, meaning they carry excess (额外的) energy. It’s this energy that causes light to be released. “I normally point out that UPE is a result of a biochemical process and in that sense is related to what happens in a glow-stick,” Dr Daniel Oblak, a physicist at the University of Calgary and last author of the study, said. “UPE is so weak that it is not visible to the human eye and completely overwhelmed by other sources of light, unless you are in a completely dark room.” That’s not to say that shutting your curtains and turning off your lights will allow you to see your own glow. This light is between 1,000 and 1,000,000 times weaker than the human eye can perceive. Using specialist cameras, scientists observed much more UPE being released by the living mice, compared to their dead bodies. Meanwhile, the leaves gave off much more light where they had been damaged, compared to undamaged areas. That’s because they were experiencing more oxidative (氧化的) stress in damaged regions. But the dead mice did not glow, because their bodies weren’t metabolising anymore. Oblak said that the key advantage of UPE is that it offers a non-invasive method of observing the health of living things. “This could be used to track the condition of a tissue — for example, for use in transplants — or the level of stress an organism is subject to, such as for monitoring crop or forest health,” he said. But this field is still full of unknowns. For instance, Oblak said, “Perhaps UPE is not just a byproduct of metabolic processes, but also serves a purpose.” Scientists just aren’t sure yet. 32．What causes ultraweak photon emission? A．Direct exposure to bright light in a dark room. B．The presence of reactive oxygen species in cells. C．The use of specialized cameras on dead organisms. D．The human eye’s ability to perceive dim light. 33．What can be learned about UPE from the text? A．It is visible to the human eye without equipment. B．It is a supernatural phenomenon. C．It is generated through a biochemical process. D．It is only produced by damaged tissues. 34．Why did the injured leaves give off more light than undamaged areas? A．They were suffering more oxidative stress. B．They were no longer metabolizing. C．They produced more reactive oxygen species after death. D．They were placed in a completely dark room. 35．What is the author’s purpose in writing the text? A．To explain why dead organisms stop glowing. B．To compare UPE in mice and plants. C．To argue that UPE is a purposeful biological signal. D．To introduce UPE and its potential applications. 第二节（共5小题：每小题2. 5分, 满分12. 5分） 阅读下面短文, 从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 Cloud storage is a flexible and convenient way to store data with complete peace of mind. 36 This means you can store all your digital things remotely, without taking up space on your computer. There are two options available: public cloud storage allows you to share hosting space with other users; private cloud storage is the ideal choice for companies who want to have their data stored in their own environment. 37 Once you have registered and set up your account, you simply save your files via the internet using your username and password. This ensures your data remains secure and inaccessible to anyone else. Should you choose, you can put certain permissions in place, which makes it easy to share your data with your colleagues or your family. When you sign up to cloud storage, you can choose the amount of space you need. 38 You can store anything digital: all your files, videos and pictures. Whether you want to use this storage solution to store your family photographs or you want to use it to store your work documentation, you will find it quite convenient. Is it better than your computer or an external drive? The answer is a definite yes. Computers crash all the time. 39 External hard drives can still break, or fail. Here you also have the added risk of misplacing it or having it stolen. There are so many advantages to cloud computing, from the ability to access your data from wherever, whenever, to not needing expensive external storage devices. 40 A．You will find cloud storage very cheap. B．Cloud storage is very simple to use. C．It enables you to store your data on hosted servers. D．This is the most common cause of lost work and memories. E．Cloud storage providers offer multiple layers of data security. F．The only disadvantage, however, is that you need internet to access files. G．You can start with a small amount and increase the storage size later on. 第三部分 语言运用（共两节，满分30分） 第一节（共15小题：每小题1分，满分15分） 阅读下面短文, 从每题所给的A、B、C、D四个选项中选出可以填入空白处的最佳选项。 Beckett Zahedi and Derrick Webster Jr. have created a website called Realer Estate.

I spent the whole summer with my face in the screen. I didn’t pay attention to my family or the things around me. Being online was more important than being with people. So, you can guess how unhappy I was when I learned what my dad planned for our family vacation that year. “This year, ” my dad said, “we’re going to do something special. We’re going camping!” It was not my dream vacation because I was still thinking about my phone. In fact, I was so busy looking at my phone that I didn’t look up until we drove across a bridge to the campsite. I looked out of the window and saw tall redwood trees. Their branches (树枝) seemed to touch the sky. I saw a river, with dark water showing between the white rapids (激流). The air from the open windows was hot. But none of that caught my eye. The reason I looked up was much more serious: my phone had no service (网络信号). The last hour in the car was hard. My dad said he had chosen a campsite with no cell service, and my phone would be useless until we got home. I would be stuck in the forest for four days with no way to reach the outside world! On the first day, I went through every teenage feeling: I was angry, I asked for help, and I kept going between sadness and anger. I went to bed angrily that night. But when I woke up in the morning, something had changed. 注意：1. 续写词数应为150个左右，可参考文中加粗词汇部分； 2. 请按如下格式在答题卡的相应位置作答。 I stopped looking at my phone and started looking around me. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ The next days went by fast because we did many fun things. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 试题 第7页（共8页） 试题 第8页（共8页） 试题 第1页（共8页） 试题 第2页（共8页） 学科网（北京）股份有限公司 $ 2026-2027学年高二选择性必修第二册英语单元自测 Unit 4 Living with Technology·基础通关 （时间：120分钟，满分：150分） 第一部分 听力（共两节，满分30分） 1—5 CBAAB 6—10 BCBCA 11—15 BACAC 16—20 BABAC 第二部分 阅读 (共两节，满分50分) 第一节 21—23 CBD 24—27 DCAB 28—31 BADC 32—35 BCAD 第二节(共5小题；每小题2.5分，满分12.5分) 36—40 CBGDF 第三部分 语言知识运用 (共两节，满分30分) 第1节 (共15小题；每小题1分，满分15分) 41—45 BADCB 46—50 ACDAD 51—55 BACCB 第二节 (共10小题；每小题1.5分，满分15分) 56．its 57．were set 58．convenience 59．platforms 60．to make 61．between 62．obtaining 63．incredibly 64．a 65．who 第四部分 写作(共两节，满分40分) 第一节 Smart Watches: A Double-Edged Sword for Students? Nowadays, smart watches are becoming increasingly popular among students. Many students wear them to school every day. The main benefit is that they can help students keep track of time and manage their schedules better, which is very useful for busy students. What’s more, some smart watches have health-monitoring functions that can remind students to exercise. However, there are also potential problems. One issue is that students may get distracted by the various apps on the watches during class, which affects their learning. In my opinion, students should use smart watches wisely and only when necessary. 第二节 （满分25分） I stopped looking at my phone and started looking around me. I walked out of the tent and saw how beautiful the forest was. The trees stood tall and quiet. Birds sang in the morning light. I saw a small river running beside the campsite. The water was so clear that I could see the stones at the bottom. For the first time, I felt peace. My dad came over with a smile. “Want to go for a walk?” he asked. I nodded. We walked along the river and talked about many things. I didn’t think about my phone at all. It felt good to just be there with him. The next days went by fast because we did many fun things. We went fishing and I caught my first fish. Dad taught me how to make a fire. We cooked together and ate under the stars. At night, we sat by the fire and told stories. I even made friends with other kids at the campsite. We played games and ran through the forest. I laughed more than I had in a long time. When it was time to go home, I felt sad to leave. On the way back, I looked at my phone but didn’t turn it on. I just looked out the window and smiled. I realized that being present is better than being online. 原创精品资源学科网独家享有版权，侵权必究！1 学科网（北京）股份有限公司1 / 2 学科网（北京）股份有限公司 $ 2026-2027学年高二选择性必修第二册英语单元自测 Unit 4 Living with Technology·基础通关 学校:___________班级：___________姓名：___________分数：___________ （时间：120分钟，满分：150分） 注意事项： 1. 答卷前，考生务必将自己的姓名、准考证号填写在答题卡上。 2. 回答选择题时，选出每小题答案后，用铅笔把答题卡上对应题目的答案标号涂黑。如需改动，用橡皮擦干净后，再选涂其他答案标号。回答非选择题时，将答案写在答题卡上，写在本试卷上无效。 3. 考试结束后，将本试卷和答题卡一并交回。 第一部分 听力（共两节，满分 30 分） 做题时，请先将答案标在试卷上。录音内容结束后，你将有两分钟的时间将试卷上的答案转涂到答题卡上。 第一节（共5小题；每小题1.5分，满分7.5分） 听下面5段对话。每段对话后有一个小题，从题中所给的A、B、C三个选项中选出最佳选项。听完每段对话后，你都有10秒钟的时间来回答有关小题和阅读下一小题。每段对话仅读一遍。 1．What are the speakers talking about?

Things were tough in the old days. W: Yes, but people were more creative back then. There was far more cultural heritage created in the past than nowadays. M: I see what you mean. The speed of life these days would prevent people from creating something like a great painting or sculpture. W: Yes, there’s a limit to what you can create when you only have a few hours after work. M: And so many people turn to watching TV or playing with their phones in their spare time. W: Yes. If we can’t create great art, we should at least make sure that we protect our heritage from damage. M: Of course. We can do that by supporting our museums. This exhibition features works of art by Picasso and Matisse. Why don’t we go there this afternoon? W: Sure. 听第9段材料，回答第14至16题。 14．What is Larry? A．A robot. B．A computer.

M: I am very pleased to be here with my friend Larry. W: This is definitely the first time I have ever shaken hands with a real live robot. That handshake was really impressing. M: He has two visual sensors in his head and he can also sense movement and pressure in his hands. He is able to recognize your hand movements as a wish to shake hands. W: Amazing, tell us how Larry came into being? M: Well, it took my team seven years to invent the first version of the robot. In the following 23 years, our aim has always been to produce a robot which can help people in their everyday tasks. W: Does Larry have someone controlling him? M: No, he’s able to get things done by himself thanks to a high-tech computer system which he carries around with him. W: I can’t see anything. Where is it then? M: It’s actually located inside his chest area. 听第10段材料，回答第17至20题。 17．Who first developed plastic on a large scale? A．An American. B．An Englishman. C．A Frenchman. 18．What was the advantage of plastic collars? A．They didn’t wear out easily. B．They were easy to wash. C．They were comfortable. 19．Why were the plastic toys a good idea for some mothers? A．They were cheap. B．They were colorful. C．Kids preferred them. 20．What is talked about at the end of the speech? A．The excitement caused by plastic. B．Different uses of plastic. C．The harmful side of plastic. 【答案】17．A 18．B 19．A 20．C 【原文】The history of plastic is no longer than you might expect. In fact, the first man-made plastic was made over a hundred years ago. It was discovered both by an Englishman and an American in the same year, but it was the American who first developed it on a large scale during the 1860s. Everybody was excited by this new material because it was so cheap. Poor workers were able to buy plastic collars. These plastic collars were hard and uncomfortable, but they were easy to wash. The poor workers could clean them every evening with just soap and water. Poor mothers, who had not been able to afford toys for their children, were now able to buy inexpensive ones made of plastic. However, plastic has one serious fault. Some kinds of plastic can catch fire very easily, and when they do, a poisonous gas is produced. What’s worse, plastic takes a very long time to break down so it causes serious pollution. We now use the term “white pollution” to refer to plastic pollution. 第二部分 阅读（共两节，满分50分） 第一节 （共15小题；每小题2.5分，满分37.5分） 阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。 A Building with 3D printing technology is sparking widespread interest in the construction industry. Besides reducing waste and our impact on the environment, it can speed up construction from weeks, or months, to days. To see how the technology can change the world around us, here are some projects that highlight bold ideas in 3D print building. Instant Neighborhood Community building takes on new meaning with the creation of a neighborhood of 3D printed homes in Tabasco, Mexico, aimed at tackling global homelessness. American non-profit New Story and tech company ICON built each concrete house from start to completion in 24 hours. New Story says its aim is to provide shelter for people without homes around the world. Nested Housing Shamballa is the idea of Italian 3D print construction company WASP. This project uses soil and straw to build a home in days that cost only 48 Euros in materials and energy. Its round designs are based on the wasp(黄蜂)nest. Each home features a laboratory with a desktop 3D printer for making furniture, artistic objects and more. Think Schools African island state Madagascar is hosting one of the world’s most forward-thinking school building projects. Non-profit Thinking Huts is using 3D print technology to provide schools where children have little or no access to education. Schools are built using local materials and low carbon concrete in under a week. Concrete Steps Researchers at the Swiss University ETH Zurich used concrete 3D printing to build the 16 metre long curved Striatus footbridge in a couple of days. The project used500 layers of concrete and53 hollow blocks, held in place by compression(压缩). This reduces materials by up to 70 percent, and the entire bridge can be pulled down and recycled. 21．What could be the inspiration behind the design of Nested Housing? A．A featured laboratory. B．A forward-thinking school C．A round wasp nest. D．A long stone bridge. 22．Which 3D construction project can be torn down and reused? A．Instant Neighborhood. B．Concrete Steps. C．Think School. D．Nested Housing. 23．What do these four 3D building projects have in common? A．They use local materials. B．They are affordable to the homeless C．They are high in cost. D．They make construction faster. 【答案】21．C 22．B 23．D 【导语】本文是一篇说明文，主要介绍了四个利用3D打印技术在建筑领域的创新项目，包括即时社区、嵌套住房、思考学校和混凝土台阶，这些项目分别针对全球无家可归问题、低成本住房、教育资源缺乏和环保建筑材料的使用，展示了3D打印技术在建筑行业中的巨大潜力和影响力。 【详解】21．细节理解题。根据“Nested Housing”部分中的“Its round designs are based on the wasp(黄蜂)nest.(它的圆形设计是基于黄蜂巢的)”可知，Nested Housing的设计灵感来源于圆形的黄蜂巢。故选C项。 22．细节理解题。根据“Concrete Steps”部分中的“This reduces materials by up to 70 percent, and the entire bridge can be pulled down and recycled.( 这可以将材料减少多达70%，而且整座桥可以被拆除并回收利用)”可知，Concrete Steps 这个3D建筑项目可以被拆除并重新利用。故选B项。 23．推理判断题。根据“Instant Neighborhood”部分中的“American non-profit New Story and tech company ICON built each concrete house from start to completion in 24 hours.( 美国非营利组织New Story和科技公司ICON合作，从开始到完成，每个混凝土房屋的建造时间仅为24小时)”、“Nested Housing”部分中的“This project uses soil and straw to build a home in days(在“嵌套式住宅”项目中，该项目使用土壤和稻草在几天内建造一个家)”、“Think Schools”部分中的“Schools are built using local materials and low carbon concrete in under a week(在“思考学校”部分，学校是使用当地材料和低碳混凝土在不到一周的时间内建成的).”以及“Concrete Steps”部分中的“Researchers at the Swiss University ETH Zurich used concrete 3D printing to build the 16 metre long curved Striatus footbridge in a couple of days(在“混凝土台阶”部分，瑞士苏黎世联邦理工学院的研究人员使用混凝土3D打印技术，在几天内建造了16米长的曲线Striatus人行桥)”可知，这四个3D建筑项目的共同之处在于它们都加快了建筑施工速度。故选D项。 B I remember doing the household chores to help my mother when I was nine. I hated changing the vacuum cleaner (真空吸尘器) bag and picking up things the machine did not clean away. Twenty years later, in 1978, with this lifelong dislike of the way the machine worked, I decided to make a bagless one. Easier said than done, of course. I didn’t realize that I would spend the next five years perfecting my design, a process that resulted in 5,127 different prototypes (样机). By the time I made my 15th prototype, my third child was born. By 2,627, my wife and I were really counting our pennies (便士). By 3,727, my wife was giving art lessons for some extra cash, and we were getting further and further into debt. These were tough times, but each failure brought me closer to solving the problem. In the early 1980s, I started trying to get licensing agreements for my technology. The reality was very different, however. The major vacuum makers had built a business model based on the profits from bags and filters (滤网). No one would license my idea, not because it was a bad one, but because it was bad for business. But soon after, the companies that I had talked with started making machines like mine. I had to fight legal battles on both sides of the Atlantic to protect the patents on my vacuum cleaner. I was still in financial difficulties until 1993, when my bank manager personally persuaded Lloyds Bank to lend me $1 million. Then I was able to go into production. Within two years, the Dyson vacuum cleaner became a best-seller in Britain. Today, I still accept risk and the potential for failure as part of the process. Nothing beats the excitement of invention. 24．What drove the author to make a bagless vacuum cleaner? A．His willingness to help mom. B．His curiosity about machines. C．His trouble in doing family chores. D．His discontent with existing cleaners. 25．What does paragraph 2 mainly tell us? A．The help from the author’s wife. B．The financial problems of the family. C．The tough process of the new invention. D．The procedures of making a bagless cleaner. 26．Why did the companies refuse to license the author’s technology? A．They thought they might suffer loss. B．They considered it not good enough. C．They faced legal problems themselves. D．They had begun making such machines. 27．What lesson may the author learn from the experience? A．Think twice before acting. B．Failure is the mother of success. C．Actions speak louder than words. D．A good beginning makes a good ending. 【答案】24．D 25．C 26．A 27．B 【导语】文章主要讲述了作者因不满现有吸尘器而发明无袋吸尘器的艰难历程及感悟。 【详解】24．细节理解题。根据第一段中“Twenty years later, in 1978, with this lifelong dislike of the way the machine worked, I decided to make a bagless one.(二十年后，也就是在 1978 年，由于一直对这种机器的运作方式感到不满，我决定制造一款无袋式机器)”可知，作者对现有吸尘器的不满促使他制造无袋吸尘器。 25．主旨大意题。根据第二段中“I didn’t realize that I would spend the next five years perfecting my design, a process that resulted in 5,127 different prototypes (样机).(我没有意识到接下来的五年我会用来完善我的设计，这个过程产生了5127个不同的样机)”以及后文描述作者在发明过程中遇到的种种困难，可知本段主要讲述新发明的艰难过程。 26．细节理解题。根据第三段中“The major vacuum makers had built a business model based on the profits from bags and filters (滤网). No one would license my idea, not because it was a bad one, but because it was bad for business.(主要的吸尘器制造商已经建立了一种基于吸尘袋和滤网利润的商业模式。没有人会批准我的想法，不是因为这是一个坏想法，而是因为这对生意不利)”可知，公司拒绝授权作者的技术是因为他们认为这可能会让他们遭受损失。 27．推理判断题。根据第二段中“These were tough times, but each failure brought me closer to solving the problem.(这些是艰难的时刻，但每一次失败都让我离解决问题更近了一步)”以及最后一段中“Today, I still accept risk and the potential for failure as part of the process. Nothing beats the excitement of invention.(今天，我仍然接受风险和失败的可能性作为过程的一部分。没有什么比发明带来的兴奋更棒的了)”可知，作者从这次经历中学到了失败是成功之母。 C Rosie, a three-year-old black Labrador dog, can do something no person in the world is able to do. She smells four containers of urine (尿液) samples and correctly chooses the one that belongs to a National Health Service patient with bladder (膀胱) cancer. To show it is not just by accident, Rosie’s trainers keep changing the order of the containers. Again and again, the dog finds the cancer sample correctly. Scientists believe this ability could be the beginning of a major change in how we detect cancer. But it has been difficult for researchers to find a way to use this on a large scale in real-world medical settings. It would simply not be practical for the health service to let a group of dogs smell patients in busy hospital waiting rooms. Now, however, technology has offered an answer. Dr Andreas Mershin, a researcher at the Massachusetts Institute of Technology, has worked with the organization Medical Detection Dogs to create an electronic nose, or “e-nose”. This device was developed by training artificial intelligence to copy the way dogs react to the smelly chemicals found in urine. Once the machine learns this, it can also “smell” urine samples by detecting those same tiny chemicals in the air. The e-nose is now being tested on more than 500 urine samples from patients at Milton Keynes University Hospital, to see if it is as accurate as the dogs. Dr Mershin hopes it can be approved as a medical tool in hospitals within two years. He also said the technology could one day even be built into smartphones. The team of scientists and dog trainers works closely with local doctors, who are very hopeful about what the e-nose could achieve. They believe it could lead to tests that do not require any cutting or entering the body. Such tests would be especially important for illnesses where people often delay getting checked because they feel embarrassed, waiting until they experience troubling symptoms. 28．What is the limitation of using dogs for cancer detection? A．They are not accurate enough. B．They are hard to use widely. C．They are too expensive to train. D．They are too difficult to control. 29．What can we infer about the e-nose? A．It may be used in phones. B．It has been applied in treatment. C．It works better than trained dogs. D．It can only detect chemicals in urine. 30．What will be possibly discussed in the following paragraph? A．Methods of keeping healthy. B．Better ways to train Rosie. C．Causes of bladder cancer. D．Further device tests. 31．What can be a suitable title for the text? A．New Ways to Train Working Dogs. B．Dogs with Special Smelling Skills. C．An AI Device for Cancer Detection. D．Traditional Tools for Bladder Cancer. 【答案】28．B 29．A 30．D 31．C 【导语】文章介绍麻省理工学院研究员联合机构研发出电子鼻（e-nose），借助人工智能模仿狗狗识别尿液中特殊化学物质的嗅觉原理，目前该设备正在医院进行样本测试，有望两年内获批成为医疗工具，未来还可能内置到智能手机中。 【详解】28．细节理解题。根据第二段“But it has been difficult for researchers to find a way to use this on a large scale in real-world medical settings(但研究人员一直很难找到一种方法，将这项技术大规模应用于现实医疗场景中。)”可知，用狗狗检测癌症的局限性是难以大规模应用于现实医疗场景。 29．推理判断题。根据第四段“He also said the technology could one day even be built into smartphones.(他还表示，这项技术有朝一日甚至能被内置到智能手机中。)”可知，关于电子鼻我们能推断出未来可能应用在手机上。 30．推理判断题。根据第四段“The e-nose is now being tested on more than 500 urine samples from patients at Milton Keynes University Hospital, to see if it is as accurate as the dogs. Dr Mershin hopes it can be approved as a medical tool in hospitals within two years.(这款电子鼻目前正在米尔顿凯恩斯大学医院，对500多份患者尿液样本进行测试，以此检验它是否能达到和嗅探犬一样的准确率。默欣博士希望它能在两年内获批，成为医院的正规医疗设备。)”可知，文章末尾讲电子鼻正在测试、等待获批医用，按照行文逻辑，下文最可能继续介绍设备的进一步测试与完善。 31．主旨大意题。通读全文，并结合第三段“Dr Andreas Mershin, a researcher at the Massachusetts Institute of Technology, has worked with the organization Medical Detection Dogs to create an electronic nose, or ‘e-nose’.(麻省理工学院的安德烈亚斯・默欣博士与医疗探测犬组织合作，研发出了一款电子鼻。)”可知，文章开篇介绍了拉布拉多犬罗西的癌症检测能力，随后说明用狗来检测癌症的方法难以大规模应用，重点讲述科学家受狗的启发研发出电子鼻，助力癌症无创检测的过程。由此可推知，C项“一款用于癌症检测的人工智能设备”最适合作文章标题。 D You, along with all living things, produce weak light that glows (发出微弱稳定的光) until you die, according to a recent study. It’s called ultraweak photon emission (UPE) and is a natural product of your metabolism (新陈代谢). UPE is produced when chemicals in your cells create unstable molecules (分子) known as reactive oxygen species (ROS) as by-products of your body’s metabolism. When ROS levels rise, they cause other molecules to become “excited”, meaning they carry excess (额外的) energy. It’s this energy that causes light to be released. “I normally point out that UPE is a result of a biochemical process and in that sense is related to what happens in a glow-stick,” Dr Daniel Oblak, a physicist at the University of Calgary and last author of the study, said. “UPE is so weak that it is not visible to the human eye and completely overwhelmed by other sources of light, unless you are in a completely dark room.” That’s not to say that shutting your curtains and turning off your lights will allow you to see your own glow. This light is between 1,000 and 1,000,000 times weaker than the human eye can perceive. Using specialist cameras, scientists observed much more UPE being released by the living mice, compared to their dead bodies. Meanwhile, the leaves gave off much more light where they had been damaged, compared to undamaged areas. That’s because they were experiencing more oxidative (氧化的) stress in damaged regions. But the dead mice did not glow, because their bodies weren’t metabolising anymore. Oblak said that the key advantage of UPE is that it offers a non-invasive method of observing the health of living things. “This could be used to track the condition of a tissue — for example, for use in transplants — or the level of stress an organism is subject to, such as for monitoring crop or forest health,” he said. But this field is still full of unknowns. For instance, Oblak said, “Perhaps UPE is not just a byproduct of metabolic processes, but also serves a purpose.” Scientists just aren’t sure yet. 32．What causes ultraweak photon emission? A．Direct exposure to bright light in a dark room. B．The presence of reactive oxygen species in cells. C．The use of specialized cameras on dead organisms. D．The human eye’s ability to perceive dim light. 33．What can be learned about UPE from the text? A．It is visible to the human eye without equipment. B．It is a supernatural phenomenon. C．It is generated through a biochemical process. D．It is only produced by damaged tissues. 34．Why did the injured leaves give off more light than undamaged areas? A．They were suffering more oxidative stress. B．They were no longer metabolizing. C．They produced more reactive oxygen species after death. D．They were placed in a completely dark room. 35．What is the author’s purpose in writing the text? A．To explain why dead organisms stop glowing. B．To compare UPE in mice and plants. C．To argue that UPE is a purposeful biological signal. D．To introduce UPE and its potential applications. 【答案】32．B 33．C 34．A 35．D 【导语】这篇文章主要介绍了超微弱光子发射（UPE）这一自然现象：它是生物新陈代谢产生的生化副产物，强度极弱无法被人眼直接观察；受损组织因氧化应激更强会释放更多UPE，而死亡生物因停止代谢不再发光。UPE可作为非侵入式手段用于生物健康监测，但其是否具有特定生物功能仍有待研究。 【详解】32．细节理解题。根据第一段中“UPE is produced when chemicals in your cells create unstable molecules (分子) known as reactive oxygen species (ROS) as by-products of your body’s metabolism. When ROS levels rise, they cause other molecules to become “excited”, meaning they carry excess (额外的) energy. It’s this energy that causes light to be released.( 当您细胞内的化学物质产生不稳定分子（即活性氧物质，简称 ROS）作为身体新陈代谢的副产品时，就会产生 UPE。当 ROS 水平升高时，它们会使其他分子“兴奋”，即它们携带过多的能量。正是这种能量导致光被释放出来。)”可知，细胞内存在活性氧物质导致了超弱光子的发射。 33．细节理解题。根据第二段““I normally point out that UPE is a result of a biochemical process and in that sense is related to what happens in a glow-stick,” Dr Daniel Oblak, a physicist at the University of Calgary and last author of the study, said.( “我通常会指出，UPE 是一种生物化学过程的结果，从这个意义上说，它与发光棒所发生的情况有关，”卡尔加里大学的物理学家丹尼尔·奥布拉克博士（该研究的最后作者）说道。)”可知，UPE 是通过生化过程产生的。 34．细节理解题。根据第五段“That’s because they were experiencing more oxidative (氧化的) stress in damaged regions. But the dead mice did not glow, because their bodies weren’t metabolising anymore.( 这是因为受损区域的生物体承受着更多的氧化应激。但死鼠不会发光，因为它们的体内不再进行新陈代谢。)”可知，受损的叶子比未受损的区域能发出更多的光是因为受损区域遭受了更多氧化应激。 35．推理判断题。根据文章大意以及最后一段“But this field is still full of unknowns. For instance, Oblak said, “Perhaps UPE is not just a byproduct of metabolic processes, but also serves a purpose.” Scientists just aren’t sure yet.( 但这一领域仍充满未知。例如，奥布拉克说：“也许UPE不仅仅是代谢过程的副产品，还具有某种作用。”科学家们目前还不确定这一点。)”可知，全文结构清晰：前四段介绍UPE的定义、产生机制和基本特性；第五段解释实验现象的原因；第六、七段重点介绍UPE在组织移植监测、作物和森林健康监测等方面的潜在应用；最后一段指出该领域仍存在未知。整体目的是全面介绍UPE及其应用前景。 第二节（共5小题：每小题2. 5分, 满分12. 5分） 阅读下面短文, 从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 Cloud storage is a flexible and convenient way to store data with complete peace of mind. 36 This means you can store all your digital things remotely, without taking up space on your computer. There are two options available: public cloud storage allows you to share hosting space with other users; private cloud storage is the ideal choice for companies who want to have their data stored in their own environment. 37 Once you have registered and set up your account, you simply save your files via the internet using your username and password. This ensures your data remains secure and inaccessible to anyone else. Should you choose, you can put certain permissions in place, which makes it easy to share your data with your colleagues or your family. When you sign up to cloud storage, you can choose the amount of space you need. 38 You can store anything digital: all your files, videos and pictures. Whether you want to use this storage solution to store your family photographs or you want to use it to store your work documentation, you will find it quite convenient. Is it better than your computer or an external drive? The answer is a definite yes. Computers crash all the time. 39 External hard drives can still break, or fail. Here you also have the added risk of misplacing it or having it stolen. There are so many advantages to cloud computing, from the ability to access your data from wherever, whenever, to not needing expensive external storage devices. 40 A．You will find cloud storage very cheap. B．Cloud storage is very simple to use. C．It enables you to store your data on hosted servers. D．This is the most common cause of lost work and memories. E．Cloud storage providers offer multiple layers of data security. F．The only disadvantage, however, is that you need internet to access files.

Computers crash all the time. (它比你的电脑或外部驱动器更好吗？答案是肯定的。电脑总是会崩溃。)”可知，此处是在比较云存储与传统存储方式（如电脑和外部驱动器）的优劣，并指出电脑容易崩溃的问题。D选项“This is the most common cause of lost work and memories. (这是工作和记忆丢失的最常见原因。)”进一步阐述了电脑崩溃的后果，即导致工作和记忆丢失，与上文紧密相连。故选D项。 40．根据上文“There are so many advantages to cloud computing, from the ability to access your data from wherever, whenever, to not needing expensive external storage devices. (云计算有很多优点，比如无论何时何地都能访问你的数据，不需要昂贵的外部存储设备。)”可知，本段主要讨论了云存储的诸多优势。F选项“The only disadvantage, however, is that you need internet to access files. (然而，唯一的缺点是你需要互联网才能访问文件。)”指出了云存储的一个潜在缺点，即需要互联网连接才能访问文件，与上文的优势形成对比，使文章更加全面和客观。故选F项。 第三部分 语言运用（共两节，满分30分） 第一节（共15小题：每小题1分，满分15分） 阅读下面短文, 从每题所给的A、B、C、D四个选项中选出可以填入空白处的最佳选项。 Beckett Zahedi and Derrick Webster Jr. have created a website called Realer Estate. It is a platform 41 to help renters more easily find proper and rent-stabilized apartments in a city where affordable housing costs are often out of 42 . Their goal is simple but powerful — make hard-to-find housing options more 43 to everyday New Yorkers. The project has become an all-consuming 44 for the teens.

I spent the whole summer with my face in the screen. I didn’t pay attention to my family or the things around me. Being online was more important than being with people. So, you can guess how unhappy I was when I learned what my dad planned for our family vacation that year. “This year, ” my dad said, “we’re going to do something special. We’re going camping!” It was not my dream vacation because I was still thinking about my phone. In fact, I was so busy looking at my phone that I didn’t look up until we drove across a bridge to the campsite. I looked out of the window and saw tall redwood trees. Their branches (树枝) seemed to touch the sky. I saw a river, with dark water showing between the white rapids (激流). The air from the open windows was hot. But none of that caught my eye. The reason I looked up was much more serious: my phone had no service (网络信号). The last hour in the car was hard. My dad said he had chosen a campsite with no cell service, and my phone would be useless until we got home. I would be stuck in the forest for four days with no way to reach the outside world! On the first day, I went through every teenage feeling: I was angry, I asked for help, and I kept going between sadness and anger. I went to bed angrily that night. But when I woke up in the morning, something had changed. 注意：1. 续写词数应为150个左右，可参考文中加粗词汇部分； 2. 请按如下格式在答题卡的相应位置作答。 I stopped looking at my phone and started looking around me. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ The next days went by fast because we did many fun things. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 【答案】 I stopped looking at my phone and started looking around me. I walked out of the tent and saw how beautiful the forest was. The trees stood tall and quiet. Birds sang in the morning light. I saw a small river running beside the campsite. The water was so clear that I could see the stones at the bottom. For the first time, I felt peace. My dad came over with a smile. “Want to go for a walk?” he asked. I nodded. We walked along the river and talked about many things. I didn’t think about my phone at all. It felt good to just be there with him. The next days went by fast because we did many fun things. We went fishing and I caught my first fish. Dad taught me how to make a fire. We cooked together and ate under the stars. At night, we sat by the fire and told stories. I even made friends with other kids at the campsite. We played games and ran through the forest. I laughed more than I had in a long time. When it was time to go home, I felt sad to leave. On the way back, I looked at my phone but didn’t turn it on. I just looked out the window and smiled. I realized that being present is better than being online. 【导语】本文以一次家庭露营为线索展开，讲述了作者沉迷手机、抗拒无信号的露营安排，却在失去网络信号后，被迫放下手机，重新发现自然与家人陪伴的美好，最终领悟到“陪伴比手机更重要”的道理。 【详解】 1. 段落续写： ①由第一段首句内容可知，第一段可描写“我”走出帐篷，开始观察森林的自然景色，在晨光、鸟鸣和清溪中感受到平静，并与父亲一起散步交谈，逐渐放下对手机的执念。 ②由第二段首句内容可知，第二段可描写“我”和家人一起开展的露营活动，在与家人和新朋友的相处中感受到快乐，最终在回家路上领悟到“陪伴比手机更重要”的道理。 2. 续写线索： 走出帐篷→观察自然→感受平静→与父亲散步→参与活动→交新朋友→领悟陪伴的可贵 3.词汇激活 行为类 ① 看见：see/catch sight of ② 走进：come over/approach 情绪类 ① 平静：peace/calmness ② 伤心的：sad/sorrowful 【点睛】【高分句型1】I walked out of the tent and saw how beautiful the forest was.(运用了how 引导的宾语从句) 【高分句型2】The water was so clear that I could see the stones at the bottom.(运用了so…that…引导的结果状语从句) 原创精品资源学科网独家享有版权，侵权必究！1 学科网（北京）股份有限公司1 / 23 学科网（北京）股份有限公司 $
