I think unmanned stores have many advantages. We can avoid waiting in line to pay，which saves us much time. Besides，we can save a lot of money in this way.（优点）However，they also have many disadvantages. For example，they are not convenient for the old，because the old are not good at using computers. One of the worst things is that the use of unmanned shops leads to the lack of communication between people. I think unmanned stores are new things for most people. It will take people some time to accept them. I think people will get used to unmanned stores soon. 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 $ 2025-2026学年九年级下册英语单元测试（徐州专用） Unit 4·培优卷 学校:___________班级：___________姓名：___________分数：___________ （时间：90分钟，满分：100分） 一、单项选择。(本大题共15小题，每小题1分，共15分) 1．A surey about protecting the Earth was ________ in our school last Friday．（　　） A．taken out B．carried out C．put out D．given out 【答案】B 【解析】上个周五，关于保护地球的一项调查在我们学校被实施． 答案：B 根据题意：上个周五，关于保护地球的一项调查在我们学校被实施．结合选项，A．取出 B．实施 C．熄灭 D．分发，选项B符合题意，故选：B。 2．His cousin went abroad at_____ age of eighteen．（　　） A．a B．an C．the D．/ 【答案】C 【解析】他的表弟十八岁时出国了． 答案：C．考查冠词．句意"他的表弟十八岁时出国了．"．at the age of…"在…岁时"，固定搭配．填定冠词the．选C． 3．We have so many kinds of guitars for you ________.（　　） A．to choose B．to choose from C．to be chosen D．to be chosen from 【答案】B 【解析】我们有很多种吉他供你从中选择。 have sth.for sb.to do 是不定式的复合结构，for sb.是不定式的逻辑主语，不定式的动作是其逻辑主语发出，不用被动语态，排除C和D；sth.是不定式的逻辑宾语，题干中的so many kinds of guitars是不定式的逻辑宾语；根据句意，我们有很多种吉他供你从中选择，即choose from the guitars。 故选：B。 4．I don't know if he______．If he _____ tomorrow，I'll call you．（　　） A．will come；comes B．comes；will come C．will come；will come D．comes；comes 【答案】A 【解析】我不知道他是否会来．如果他明天来，我会打电话给你． 答案：A．考查一般将来时态．第一个空，if引导的宾语从句，意思是"是否"．从句用一般将来时态．第二个空，if引导的条件状语从句，意思是"如果"．主句用一般将来时态，从句用一般现在时态，从句主语he他，第三人称单数．谓语动词用第三人称单数comes． 故选：A。 5．The water in the river smells terrible． People must dirty things into it．（　　） A．be stopped to throw B．be stopped from throwing C．stop to throw D．stop from throwing 【答案】B 【解析】河里的水闻起来很难闻．必须阻止人们往里扔脏东西． 根据People must dirty things into it，是指必须阻止人们往里扔脏东西．主语people是动作的承受者，must be+过去分词．stop sb from doing sth阻止某人做某事． 故选：B． 6．﹣Mum， Tony broke my pen again．﹣Forget it． ________， he's only two years old．（　　） A．After all B．All the time C．Not at all D．First of all 【答案】A 【解析】妈妈，Tony 又把我的笔弄坏了． ﹣﹣原谅他吧，他毕竟只有2岁． 所给的四个答案意思分别是：after all 毕竟； all the time一直，not at all 不用谢，一点都不；first of all 首先．本题是一个对话．第一句的大意是说话人向妈妈述说Tony把他/她的笔弄坏了．第二句的大意是他/她妈妈请他/她忘记这件事，毕竟Tony只是一个两岁的孩子．所以after all符合句意． 故选：A。 7．Food on Mars will not be as as it is on the Earth．（　　） A．tasty B．taste C．tastier D．tastes 【答案】A 【解析】火星上的食物将不像地球上的那样美味． 根据 as as，可知是原级比较，用形容词或副词原形，表示"和…一样"． 故选：A． 8．Sandy was too nervous_________the teacher's question．（　　） A．answer B．to answer C．answering D．answers 【答案】B 【解析】Sandy太紧张了以致于不能回答老师的问题． too…to…太…以致不能…，是一个含有否定含义的固定短语，to与后面的动词原形构成不定式；answer回答，所以此处要用to answer，故选B． 9．﹣How nice that Lucy has been invited to the party too! ﹣Well，Lucy not come．She is not certain whether her mother will allow her to go to the party．（　　） A．might B．would C．must D．need 【答案】A 【解析】﹣﹣Lucy也被邀请去参加晚会，真是太好了！ ﹣﹣哦，Lucy可能来不了．她不确定她的妈妈是否允许她去参加聚会． 答案：A might，可能；would，愿意；must，必须，一定；need，需要．根据She is not certain可知，Lucy可能来不了， 故选：A． 10．Televisions have made _____ possible for us to watch movies at home．（　　） A．that B．this C．it D．they 【答案】C 【解析】电视已经使我们在家看电影成为可能的事情． 答案：C 根据此句句子的结构，make it+adj．+to do sth．为固定结构，意为"使做某事是…的"．这里it是形式宾语，代替后面的动词不定式，其他选项无此用法．故选C． 11．With the________ of society our environment is becoming worse and worse．So we should do what we can our environment．（　　） A．develop，protect B．developing，to protect C．development，protect D．development，to protect 【答案】D 【解析】随着社会的发展，我们的环境变得越来越糟．因此我们应该做些能保护我们的环境的事情． 根据With the________ of society 这一部分，判断符合With+名词+介词短语的情况，后面的介词短语作了名词的补语，整个短语作状语，表明状态或方式，故第一个空应该用develop的名词形式development；根据So we should do 判断后应该用动词不定式作目的状语， what we can作do的宾语，构成宾语从句． 故选：D． 12．﹣﹣﹣Shall we make a cake by ourselves instead of buying one？ ﹣﹣﹣______________．（　　） A．That's a good idea B．Don't worry C．Never mind D．The same to you 【答案】A 【解析】我们应该自己做一个蛋糕，而不是买一个．这个主意真不错． 答案：A 考查情境对话．句意：我们应该自己做一个蛋糕，而不是买一个．这个主意真不错．A． That's a good idea 这个主意真不错 B． Don't worry 别担心C． Never mind 不要紧．D． The same to you 你也一样．根据题干Shall we make a cake by ourselves instead of buying one？可知这个主意真不错．故选A． 13．About of the books in our school library are written in Chinese．（　　） A．four﹣fifth B．four﹣fifths C．fourth﹣fifths D．fourths﹣fifth 【答案】B 【解析】﹣﹣我们学校图书馆大约五分之四的书是用汉语写的． 答案：B 根据英语中分数的写法规则为：分子用基数词：one，two，three等，分母用序数词：first，second，third等，分子大于一，分母加s，根据选项知考查五分之四的写法，分子为基数词four，分母为序数词fifth，分子大于一，故分母后需加s，故选B． 14．_____ on Mars have to wear special boots _____ themselves heavier．（　　） A．Humen； to make B．Humans； to make C．Human； to make D．Humans； making 【答案】B 【解析】在火星上的人必须穿特殊的靴子以使自己更重些． 答案为B．human做"人"的意思的时候是一个可数名词，a human，humans，这里的谓语动词为have，应用复数humans，所以排除AC；另外不定式在此句中作目的状语，故选：B。 15．﹣How was your visit to the Olympic Park？﹣Pretty good．___________．（　　） A．By underground B．A taxi driver took me there C．I went there alone D．It's well worth a visit 【答案】D 【解析】你对奥林匹克公园的访问感觉怎样的？非常好．很值得一看． 答案：D 考查情境对话．句意：你对奥林匹克公园的访问感觉怎样的？非常好．很值得一看．A． By underground乘地铁 B． A taxi driver took me there 一个出租车司机把我带在那里 C． I went there alone 我单独去那里 D． It's well worth a visit 很值得一看．根据题干Pretty good．可知应说很值得一看．故选D． 二、完形填空。(本大题共15小题，每小题1分，共15分) Now，the smart mobile phones are getting more and more popular not only with the young but also with the old.

Monkeys know how to use simple tools. Elephants can be taught how to count. But things like art，literature（文学），the Internet，and space travel have only been made possible by the amazing intelligence of humans. And yet，there are some who believe that we can create machines that can think and feel just like we do. Artificial intelligence（人工智能），or AI，is defined（定义为）by Merriam﹣Webster as "the capability of a machine to imitate intelligent human behavior". AI is around us every day. From Apple's voice﹣activated assistant Siri to the software algorithms（算法）that shipping companies use to deal with deliveries（投递），AI is very much a part of our lives. But why do we put so much effort into creating machines that can think the way we do？For one thing，AI can make our lives much easier. Imagine being able to be in a car，tell it your destination，and sit back in comfort as the AI﹣guided self﹣driving car takes you there. We're already getting there﹣Changsha became the first city in China to roll out self﹣driving taxis in April 2020. However，there are risks. What if we somehow produced an artificial intelligence that was smarter than us？How would it behave toward us？These are the kinds of difficult questions that AI researchers ask themselves all the time. Apart from the risks，it is already clear that AI is here to stay. Only time will tell if it will lead us into a new age of prosperity（繁荣），or be our end. （31）The first paragraph is written to 　 　 . A．explain how animals are intelligent B．show what fields AI can be used in C．prove the possibility of space travel D．explain how intelligence makes humans special （32）Which of the following might not take advantage of AI？ 　 　 A．Voice﹣activated assistants. B．Software algorithms for deliveries. C．Machines that produce goods. D．Self﹣driving taxis. （33）What is one of the risks about AI？ 　 　 A．We might not be able to live without it in the future. B．We can't say for sure how AI will behave toward us. C．AI will never be as smart as humans. D．It is not easy to put AI into daily use. （34）What does the underlined word "destination" in Paragraph 4 refer to？ 　 　 A．An end point. B．A name. C．A wish D．A feeling. （35）What's the writer's attitude towards AI？ 　 　 A．It will be good. B．It will be bad. C．It's going to be part of our future. D．It's risky and horrible. 【答案】DCBAC 【解析】本文主要介绍了AI科学技术来的生活便利以及其潜在的风险。 （31）段落大意题。根据But things like art，literature（文学），the Internet，and space travel have only been made possible by the amazing intelligence of humans.（像艺术、文学、互联网和太空旅行这样的事情，有靠人类惊人的智慧才能成为可能。）可知，因此第一段主要讲了智力如何使人类变得特别。故选D。 （32）细节理解题。根据From Apple's voice﹣activated assistant Siri to the software algorithms.和as the AI﹣guided self﹣driving car takes you there.（从苹果的语音激活助手Siri到软件算法。）和（当人工智能引导的自动驾驶汽车带你去那里时。）可知，自驾驶、苹果的声控助手以及软件算法都利用AI技术。故选C。 （33）细节理解题。根据What if we somehow produced an artificial intelligence that was smarter than us？How would it behave toward us？（如果我们制造了一个比我们更职明的人工智能呢？它会如何对待我们？）可知人工智能的风险之一是我们不能确定人工智将如何对待我们。故选B。 （34）词义猜测题。根据后面句子 sit back in comfort as the AI﹣guided self﹣driving car takes you there.（可知，你只要舒适地坐着，由人工智能引导自动驾驶汽车会带你去那里，）因此可推测destination代指"你要去的地方或者终点"。故选A。 （35）观点态度题。根据Apart from the risks，it is already clear that AI is here to stay.Only time will tell if it will lead us into a new age of prosperity（繁荣），or be our end.（除了风险之外，人工智能显然将继续存下去。只有时间才能告诉我们，它会引领我进入一个繁荣的新时代，还是我们的末日。）可知，作者认为AI技术将会是我们未来生活的一部分。故选C。 B Would you like to live in a city where buildings turn the lights off for you，and self﹣driving cars will find the nearest parking space themselves？Although it might sound a little far from you now，living in a "smart" city like this could happen sooner than you think. Great changes have taken place in towns that we have lived in for centuries，while completely new cities are being built. One such place is the city of Songdo. Every home there will have a "telepresence" system（远程遥控系统）﹣allowing users to control household appliances（家用电器），take part in video meetings，and receive education，healthcare and government services. Around the city，escalators （自动扶梯） will only move when someone is on them，and offices and schools will all be in the big system as well. The great mind behind Songdo is from the company Cisco. In fact，technology companies around the world such as IBM，Siemens and Microsoft are already in the business. About 75% of the world's population will live in cities by 2050，so cities will need to be more modern to deal with the coming problems. "Making cities smarter is one way out，and I think this will in turn make cities greener，" said Dan Hill，head of a research company. （36）According to the text，living in a "smart" city 　 　 .

But Chinese scientists can now tell you：Maybe you can. Scientists from Tianjin Institute of Industrial Biotechnology of the Chinese Academy of Sciences made a big breakthrough. They have turned carbon dioxide（CO2，二氧化碳），the "infamous"（声名狼藉的）greenhouse gas，into starch （淀粉）. Starch is the main part of the flour，rice and corn that we eat every day. It's created by plants through photosynthesis（光合作用）.But according to the team's director Ma Yanhe，plants do this in a complex（复杂的）and inefficient（低效的） way，which takes about 60 steps. The new study，after six years of hard work，has found a simpler way to do this，with only 11 steps. "Our study shows that creating complex compounds（化合物）like starch is possible in a lab（实验室），and there are many areas that can benefit from this technology， " Ma told China Daily. The scientists first turned CO2 and hydrogen gas into methanol （甲醇）.Then they pieced these methanol molecules（分子） into bigger and more complex molecules. Finally the starch came out. This method makes it possible to produce food in factories，replacing traditional farming. This will not only help make plenty of starchy crops（农作物）such as potatoes，but also save water，fertilizer（肥料）and land. It may also help recycle CO2 to deal with climate change，according to China Daily. The study can benefit space exploration too. Astronauts no longer need to worry about their food as they travel in space. They may simply turn the CO2 they breathe into the food they eat! （41）What's the main part of flour，rice and corn？ A．Water. B．Starch. C．CO2. D．Methanol. （42）Compared with the process used by plants，it's __________ to make starch using CO2. A．harder B．more complex C．easier D．more time-consuming （43）From Paragraph 5，we can learn 　 　 . A．how starch is made from CO2 B．what scientists researched in the past C．why the research is meaningful D．where the CO2 used in the study comes from （44）How does the new findings help us？ a.It helps to protect our environment. b.It provides people with more healthy food. c.It benefits the food problems of astronauts. d.It helps to save natural resources. A．abc B．bcd C．acd D．abd （45）What's the best title of this passage？ A．Environmental protection. B．Astronaut food. C．The air you can eat. D．How to make methanol from CO2. 【答案】BCACC 【解析】本文主要向我们介绍了把二氧化碳转化为淀粉的新技术以及该技术的优点。 （41）B.细节理解题。根据Starch is the main part of the flour，rice and corn that we eat every day.淀粉是我们每天吃的面粉、大米和玉米的主要成分。可知，面粉、大米和玉米的主要成分是淀粉。故选B。 （42）C.细节理解题。根据But according to the team's director Ma Yanhe，plants do this in a complex（复杂的）and inefficient（低效的） way，which takes about 60 steps.The new study，after six years of hard work，has found a simpler way to do this，with only 11 steps.但据该团队的负责人马彦河说，植物的这种做法复杂而低效，大约需要60步。经过6年的努力，这项新研究发现了一种更简单的方法，只需11步。可知，与植物生产淀粉的过程相比，利用二氧化碳更容易生产淀粉。故选C。 （43）A.段落大意题。根据The scientists first turned CO2 and hydrogen gas into methanol （甲醇）.Then they pieced these methanol molecules（分子） into bigger and more complex molecules.Finally the starch came out.科学家们首先将二氧化碳和氢气转化成甲醇，然后将这些甲醇分子拼接成更大更复杂的分子。最后淀粉出来了。可知，第五段主要是在向我们介绍淀粉是如何从二氧化碳中提炼出来的。故选A。 （44）C.细节判断题。根据This will not only help make plenty of starchy crops（农作物）such as potatoes，but also save water，fertilizer（肥料）and land.It may also help recycle CO2 to deal with climate change.这不仅有助于生产大量的淀粉类作物，如土豆，而且还能节约水、肥料和土地。它还可以帮助回收二氧化碳来应对气候变化。以及The study can benefit space exploration too.Astronauts no longer need to worry about their food as they travel in space.这项研究也有利于太空探索。宇航员在太空旅行时不再需要担心食物问题。可知，这些新发现有助于保护环境，有助于解决宇航员的食物问题和节约自然资源。只有b"它为人们提供了更健康的食物。"文中未提及。故选C。 （45）C.最佳标题题。根据They have turned carbon dioxide（CO2，二氧化碳），the "infamous"（声名狼藉的）greenhouse gas，into starch （淀粉）.他们已经将"臭名昭著的"温室气体二氧化碳转化为淀粉。以及通读全文可知，本文主要向我们介绍了把二氧化碳转化为淀粉的新技术以及该技术的优点。C选项"你可以吃的空气。"符合主题，故选C。 四、短文还原。(本大题共5小题，每小题2分，共10分) On August 20,2021，Chinese astronauts Liu Boming and Nie Haisheng did the second spacewalk of the Shenzhou XII mission （任务）.They set up equipment （设备） and lifted a camera outside the Tiangong space station （空间站）. （46）　 　 .There is no air in space，of course. And it's filled with harmful radiation （辐射）.But the spacesuits （宇航服）can protect astronauts.

Monkeys know how to use simple tools. Elephants can be taught how to count. But things like art，literature（文学），the Internet，and space travel have only been made possible by the amazing intelligence of humans. And yet，there are some who believe that we can create machines that can think and feel just like we do. Artificial intelligence（人工智能），or AI，is defined（定义为）by Merriam﹣Webster as "the capability of a machine to imitate intelligent human behavior". AI is around us every day. From Apple's voice﹣activated assistant Siri to the software algorithms（算法）that shipping companies use to deal with deliveries（投递），AI is very much a part of our lives. But why do we put so much effort into creating machines that can think the way we do？For one thing，AI can make our lives much easier. Imagine being able to be in a car，tell it your destination，and sit back in comfort as the AI﹣guided self﹣driving car takes you there. We're already getting there﹣Changsha became the first city in China to roll out self﹣driving taxis in April 2020. However，there are risks. What if we somehow produced an artificial intelligence that was smarter than us？How would it behave toward us？These are the kinds of difficult questions that AI researchers ask themselves all the time. Apart from the risks，it is already clear that AI is here to stay. Only time will tell if it will lead us into a new age of prosperity（繁荣），or be our end. （31）The first paragraph is written to 　 　 . A．explain how animals are intelligent B．show what fields AI can be used in C．prove the possibility of space travel D．explain how intelligence makes humans special （32）Which of the following might not take advantage of AI？ 　 　 A．Voice﹣activated assistants. B．Software algorithms for deliveries. C．Machines that produce goods. D．Self﹣driving taxis. （33）What is one of the risks about AI？ 　 　 A．We might not be able to live without it in the future. B．We can't say for sure how AI will behave toward us. C．AI will never be as smart as humans. D．It is not easy to put AI into daily use. （34）What does the underlined word "destination" in Paragraph 4 refer to？ 　 　 A．An end point. B．A name. C．A wish D．A feeling. （35）What's the writer's attitude towards AI？ 　 　 A．It will be good. B．It will be bad. C．It's going to be part of our future. D．It's risky and horrible. B Would you like to live in a city where buildings turn the lights off for you，and self﹣driving cars will find the nearest parking space themselves？Although it might sound a little far from you now，living in a "smart" city like this could happen sooner than you think. Great changes have taken place in towns that we have lived in for centuries，while completely new cities are being built. One such place is the city of Songdo. Every home there will have a "telepresence" system（远程遥控系统）﹣allowing users to control household appliances（家用电器），take part in video meetings，and receive education，healthcare and government services. Around the city，escalators （自动扶梯） will only move when someone is on them，and offices and schools will all be in the big system as well. The great mind behind Songdo is from the company Cisco. In fact，technology companies around the world such as IBM，Siemens and Microsoft are already in the business. About 75% of the world's population will live in cities by 2050，so cities will need to be more modern to deal with the coming problems. "Making cities smarter is one way out，and I think this will in turn make cities greener，" said Dan Hill，head of a research company. （36）According to the text，living in a "smart" city 　 　 . A．is very expensive B．may soon become true C．may cause problems D．is popular with old people （37）What is the second paragraph mainly about？ 　 　 A．A meeting in Songdo. B．A city of the future. C．A plan to build a house. D．A report on public health. （38）Which company offers the great mind to build Songdo？ 　 　 A．Cisco. B．IBM. C．Siemens. D．Microsoft. （39）Dan Hill thinks that making cities smarter is one way to 　 　 . A．drive people out of cities B．develop his research company C．solve the cities' coming problems D．control the world's population （40）What would be the best title for the text？ 　 　 A．Smart Cities B．Future Education C．Famous Companies D．Government Services C People often say，"You can't live only on air." But Chinese scientists can now tell you：Maybe you can. Scientists from Tianjin Institute of Industrial Biotechnology of the Chinese Academy of Sciences made a big breakthrough. They have turned carbon dioxide（CO2，二氧化碳），the "infamous"（声名狼藉的）greenhouse gas，into starch （淀粉）. Starch is the main part of the flour，rice and corn that we eat every day. It's created by plants through photosynthesis（光合作用）.But according to the team's director Ma Yanhe，plants do this in a complex（复杂的）and inefficient（低效的） way，which takes about 60 steps. The new study，after six years of hard work，has found a simpler way to do this，with only 11 steps. "Our study shows that creating complex compounds（化合物）like starch is possible in a lab（实验室），and there are many areas that can benefit from this technology， " Ma told China Daily. The scientists first turned CO2 and hydrogen gas into methanol （甲醇）.Then they pieced these methanol molecules（分子） into bigger and more complex molecules. Finally the starch came out. This method makes it possible to produce food in factories，replacing traditional farming. This will not only help make plenty of starchy crops（农作物）such as potatoes，but also save water，fertilizer（肥料）and land. It may also help recycle CO2 to deal with climate change，according to China Daily. The study can benefit space exploration too. Astronauts no longer need to worry about their food as they travel in space. They may simply turn the CO2 they breathe into the food they eat! （41）What's the main part of flour，rice and corn？ A．Water. B．Starch. C．CO2. D．Methanol. （42）Compared with the process used by plants，it's __________ to make starch using CO2. A．harder B．more complex C．easier D．more time-consuming （43）From Paragraph 5，we can learn 　 　 . A．how starch is made from CO2 B．what scientists researched in the past C．why the research is meaningful D．where the CO2 used in the study comes from （44）How does the new findings help us？ a.It helps to protect our environment. b.It provides people with more healthy food. c.It benefits the food problems of astronauts. d.It helps to save natural resources. A．abc B．bcd C．acd D．abd （45）What's the best title of this passage？ A．Environmental protection. B．Astronaut food. C．The air you can eat. D．How to make methanol from CO2. 四、短文还原。(本大题共5小题，每小题2分，共10分) On August 20,2021，Chinese astronauts Liu Boming and Nie Haisheng did the second spacewalk of the Shenzhou XII mission （任务）.They set up equipment （设备） and lifted a camera outside the Tiangong space station （空间站）. （46）　 　 .There is no air in space，of course. And it's filled with harmful radiation （辐射）.But the spacesuits （宇航服）can protect astronauts.

Monkeys know how to use simple tools. Elephants can be taught how to count. But things like art，literature（文学），the Internet，and space travel have only been made possible by the amazing intelligence of humans. And yet，there are some who believe that we can create machines that can think and feel just like we do. Artificial intelligence（人工智能），or AI，is defined（定义为）by Merriam﹣Webster as "the capability of a machine to imitate intelligent human behavior". AI is around us every day. From Apple's voice﹣activated assistant Siri to the software algorithms（算法）that shipping companies use to deal with deliveries（投递），AI is very much a part of our lives. But why do we put so much effort into creating machines that can think the way we do？For one thing，AI can make our lives much easier. Imagine being able to be in a car，tell it your destination，and sit back in comfort as the AI﹣guided self﹣driving car takes you there. We're already getting there﹣Changsha became the first city in China to roll out self﹣driving taxis in April 2020. However，there are risks. What if we somehow produced an artificial intelligence that was smarter than us？How would it behave toward us？These are the kinds of difficult questions that AI researchers ask themselves all the time. Apart from the risks，it is already clear that AI is here to stay. Only time will tell if it will lead us into a new age of prosperity（繁荣），or be our end. （31）The first paragraph is written to 　 　 . A．explain how animals are intelligent B．show what fields AI can be used in C．prove the possibility of space travel D．explain how intelligence makes humans special （32）Which of the following might not take advantage of AI？ 　 　 A．Voice﹣activated assistants. B．Software algorithms for deliveries. C．Machines that produce goods. D．Self﹣driving taxis. （33）What is one of the risks about AI？ 　 　 A．We might not be able to live without it in the future. B．We can't say for sure how AI will behave toward us. C．AI will never be as smart as humans. D．It is not easy to put AI into daily use. （34）What does the underlined word "destination" in Paragraph 4 refer to？ 　 　 A．An end point. B．A name. C．A wish D．A feeling. （35）What's the writer's attitude towards AI？ 　 　 A．It will be good. B．It will be bad. C．It's going to be part of our future. D．It's risky and horrible. B Would you like to live in a city where buildings turn the lights off for you，and self﹣driving cars will find the nearest parking space themselves？Although it might sound a little far from you now，living in a "smart" city like this could happen sooner than you think. Great changes have taken place in towns that we have lived in for centuries，while completely new cities are being built. One such place is the city of Songdo. Every home there will have a "telepresence" system（远程遥控系统）﹣allowing users to control household appliances（家用电器），take part in video meetings，and receive education，healthcare and government services. Around the city，escalators （自动扶梯） will only move when someone is on them，and offices and schools will all be in the big system as well. The great mind behind Songdo is from the company Cisco. In fact，technology companies around the world such as IBM，Siemens and Microsoft are already in the business. About 75% of the world's population will live in cities by 2050，so cities will need to be more modern to deal with the coming problems. "Making cities smarter is one way out，and I think this will in turn make cities greener，" said Dan Hill，head of a research company. （36）According to the text，living in a "smart" city 　 　 . A．is very expensive B．may soon become true C．may cause problems D．is popular with old people （37）What is the second paragraph mainly about？ 　 　 A．A meeting in Songdo. B．A city of the future. C．A plan to build a house. D．A report on public health. （38）Which company offers the great mind to build Songdo？ 　 　 A．Cisco. B．IBM. C．Siemens. D．Microsoft. （39）Dan Hill thinks that making cities smarter is one way to 　 　 . A．drive people out of cities B．develop his research company C．solve the cities' coming problems D．control the world's population （40）What would be the best title for the text？ 　 　 A．Smart Cities B．Future Education C．Famous Companies D．Government Services C People often say，"You can't live only on air." But Chinese scientists can now tell you：Maybe you can. Scientists from Tianjin Institute of Industrial Biotechnology of the Chinese Academy of Sciences made a big breakthrough. They have turned carbon dioxide（CO2，二氧化碳），the "infamous"（声名狼藉的）greenhouse gas，into starch （淀粉）. Starch is the main part of the flour，rice and corn that we eat every day. It's created by plants through photosynthesis（光合作用）.But according to the team's director Ma Yanhe，plants do this in a complex（复杂的）and inefficient（低效的） way，which takes about 60 steps. The new study，after six years of hard work，has found a simpler way to do this，with only 11 steps. "Our study shows that creating complex compounds（化合物）like starch is possible in a lab（实验室），and there are many areas that can benefit from this technology， " Ma told China Daily. The scientists first turned CO2 and hydrogen gas into methanol （甲醇）.Then they pieced these methanol molecules（分子） into bigger and more complex molecules. Finally the starch came out. This method makes it possible to produce food in factories，replacing traditional farming. This will not only help make plenty of starchy crops（农作物）such as potatoes，but also save water，fertilizer（肥料）and land. It may also help recycle CO2 to deal with climate change，according to China Daily. The study can benefit space exploration too. Astronauts no longer need to worry about their food as they travel in space. They may simply turn the CO2 they breathe into the food they eat! （41）What's the main part of flour，rice and corn？ A．Water. B．Starch. C．CO2. D．Methanol. （42）Compared with the process used by plants，it's __________ to make starch using CO2. A．harder B．more complex C．easier D．more time-consuming （43）From Paragraph 5，we can learn 　 　 . A．how starch is made from CO2 B．what scientists researched in the past C．why the research is meaningful D．where the CO2 used in the study comes from （44）How does the new findings help us？ a.It helps to protect our environment. b.It provides people with more healthy food. c.It benefits the food problems of astronauts. d.It helps to save natural resources. A．abc B．bcd C．acd D．abd （45）What's the best title of this passage？ A．Environmental protection. B．Astronaut food. C．The air you can eat. D．How to make methanol from CO2. 四、短文还原。(本大题共5小题，每小题2分，共10分) On August 20,2021，Chinese astronauts Liu Boming and Nie Haisheng did the second spacewalk of the Shenzhou XII mission （任务）.They set up equipment （设备） and lifted a camera outside the Tiangong space station （空间站）. （46）　 　 .There is no air in space，of course.
