Most new babies are born in the developing countries. These countries are found in Africa, South America and parts of Asia. In the developed countries of Europe and North America, the population is growing very slowly. This is because women in these countries have, on average (平均), only one or two children. In the developing countries, many women have five or more children. In 1950, about one quarter of the world’s population lived in the developed countries. By 2050, these countries will be home to only about one tenth of the world’s people. In the developing countries, more than one billion people are still living below the poverty (贫困) line. These people do not have enough food to eat and they live in poor housing conditions. Children get little time at school and suffer (遭受痛苦) from many kinds of diseases. At the beginning of the 21st century, the world’s population was around six billion. The U.N. has said that the world’s population will level off (平稳下降) at 12.5 billion by the year 2100. Other groups think the world’s population will continue to grow, reaching 14 billion before it becomes stable (稳定的), or even falls. 根据短文内容，回答下列问题。 1．In what areas of the world can we find developing countries? 2．What was the population at the beginning of the 21st century? 3．In 1950, what percent (百分之) of the world’s population lived in the developing countries? 4．Is the population in the developed countries growing very slowly?

Do you know that many people are trying to learn a new language these days? Some of them consider it as a hobby, while others have to learn a new language because it is needed by their jobs or study. As a foreigner who is really interested in Chinese culture, I like learning Chinese. It is thought that a person needs to know at least 3,000 Chinese characters (汉字) to understand most Chinese newspapers. The problem for most foreigners, however, is that knowing 3,000 characters sounds like an impossible task. For foreigners, many Chinese characters look the same. That’s why some people give up halfway. It’s the most difficult part for me, too. But I am able to learn how to write each character by watching videos online. Whenever I saw a character I didn’t know in the street or on a menu, I would write it down and then look it up. Slowly I’ve learnt the characters that are common in daily life. As for speaking, I talk about different topics in Chinese in my daily life. It is the secret to practising speaking and helps me to think in a Chinese way. For example, whenever I am going to a shop, I would think about how to say things in Chinese. Learning a second language is never easy. But I believe that if I try my best, I can achieve my goal. 1．Why does Adam learn Chinese? 2．How many Chinese characters does a person need to know to understand most Chinese newspapers? 3．How does Adam learn to write Chinese characters? 4．What is Adam’s secret to practising speaking? 5．What does Adam think of learning a second language? 【答案】1．Because he is a foreigner who is really interested in Chinese culture. 2．At least 3,000. 3．He learns to write Chinese characters by watching videos online.

My name is Jeff. I like learning foreign languages. When I retired (退休) in 2018, I could speak three foreign languages. At that time, my biggest wish was to learn a new one. Later, I watched a program about Chinese culture on TV. I was so interested in it that I made the decision to learn Chinese. I found a cultural center in the north of London by chance. It offered Chinese language courses fit for me. In March 2019, I began to learn. To attend the classes, I left my home at 5 a.m. every Saturday and drove 3 hours to the cultural center. But this didn’t stop me. After class, I practiced a lot. Through learning, I developed a love for Chinese poems and joined in activities like Chinese poetry readings. I increasingly dreamed of visiting China. My Chinese teacher Mr. Liu always mentioned “It’s better to travel ten thousand miles than to read ten thousand books”. He suggested that I should take part in a study tour in China. So in August 2024, I visited Xi’an with my classmates of the cultural center. During the trip, as the student best at Chinese among us, I tried to act as an interpreter (口译员). I helped my classmates in many ways like asking the way and shopping in Chinese. This experience encouraged me to study further. The British often say “Learning is a lifelong pursuit (追求)”, which means “It is never too late to learn”. I will keep on learning Chinese, hoping to be a lifelong learner. I believe that learning Chinese will bring even more possibilities to my life. 1．When did Jeff begin to learn Chinese?（不超过5个词） 2．Who suggested a study tour in China?（不超过10个词） 3．What do you think of Jeff?（不超过10个词） 【答案】1．In March 2019. 2．Jeff’s Chinese teacher Mr. Liu. 3．He is a determined and hard-working lifelong learner. 【导语】本文是一篇记叙文，讲述了退休后的Jeff因热爱中国文化而学习中文，并克服困难坚持学习，最终通过中国之旅实践语言，立志成为终身学习者的故事。 1．根据“In March 2019, I began to learn.”可知，杰夫于2019年3月开始学习中文，故填In March 2019. 2．根据“My Chinese teacher Mr. Liu always mentioned…He suggested that I should take part in a study tour in China”可知，是杰夫的中文老师刘先生建议去中国进行学习之旅，故填Jeff’s Chinese teacher Mr. Liu. 3．回答合理即可。参考答案：He is a determined and hard-working lifelong learner.

Usually, we think workers will pick tea leaves by hand. But now, some Longjing tea is being picked by special workers—tea-picking robots! In a tea garden in Hangzhou, a smart tea-picking robot invented by Zhejiang Sci-Tech University has started working. “We take thousands of pictures of new tea buds (芽) and input them into the robot for it to learn. The robot uses an AI model to recognize (识别) the buds it should pick,” said Professor Chen Jianneng, a member of the research team. This helps the robot find the right tea buds about 90 percent of the time. The robot’s arm pulls the tea buds and then sucks (吸) them up. These buds are quickly moved into a special box. Once the robot has collected all the buds from the area it’s working at, it moves the buds from the box to a main box that holds everything it collects. The robot was made because there are not enough people to pick tea. In Zhejiang, about 400,000 pickers are needed now. “Picking is the greatest challenge for the development of the tea industry (产业),” said Professor Wu Chuanyu, who leads the research team. “About five years from now, the robots will do the job of picking West Lake Longjing tea instead of people,” Wu added. 1．Who is Longjing tea being picked by now? 2．How does the robot recognize the new tea buds? 3．What will the robot do after collecting all the buds from the area it’s working at? 4．How many pickers are needed in Zhejiang? 5．What do you think of the tea-picking robot? 【答案】1．Tea-picking robots. 2．By using an AI model. 3．It will move the buds to a main box that holds everything it collects. 4．About 400,000. 5．It is a great help to the tea industry./It’s very helpful./… 【导语】本文主要介绍了西湖龙井茶的采摘现状，以及由浙江理工大学发明的智能采茶机器人如何工作，包括其识别茶芽、采摘和收集茶芽的过程，还提及了研发该机器人的原因及未来展望。 1．根据第一段“But now, some Longjing tea is being picked by special workers—tea-picking robots!”可知，现在一些龙井茶正由特殊的工人——采茶机器人采摘。故填Tea-picking robots. 2．根据第二段“The robot uses an AI model to recognize (识别) the buds it should pick”可知，机器人通过使用人工智能模型来识别它应该采摘的茶芽。故填By using an AI model. 3．根据第三段“Once the robot has collected all the buds from the area it’s working at, it moves the buds from the box to a main box that holds everything it collects.”可知，机器人从它工作的区域收集完所有的芽后，会把芽从盒子里移到一个主盒子里，这个主盒子装着它收集的所有东西。故填It will move the buds to a main box that holds everything it collects. 4．根据第四段“In Zhejiang, about 400,000 pickers are needed now.”可知，在浙江，现在大约需要40万名采摘者。故填About 400,000. 5．这是一个开放性问题，答案因人而异。但可以根据文章内容和常识来回答。故填It is a great help to the tea industry./It’s very helpful./… 阅读短文，然后根据内容回答问题。 China’s “four great new inventions” in modern times have made the daily life of the public more and more convenient. They are the high-speed railway (HSR), shopping online, shared bikes and mobile phone payment. Living in Hong Kong, I knew them from the papers, the TV and the Internet. But last month I had the chance to experience all of them. As usual, the golden week stopped the traffic. It was hard to get a railway ticket anywhere in the train stations. But I bought a train ticket to Beijing on the Internet and paid for it through Zhifubao. It was even cheaper than it was bought in the station. Then we got on the high-speed train. I was shocked at its speed and quietness. There was no noise which the train made while running. It was reported that China has the longest high-speed railway in the world, which is regarded as a “name card” for China. Did I feel bored during the trip on the train? Not at all. I bought many cheap and good things in Taobao and Tmall on the Internet through my mobile phone. It’s amazing that there are oceans of products in Taobao and Tmall. Soon we arrived in Beijing. We got on a bus near the train station. After getting off the bus, my friend told me that the bus stop is far from his home. I thought we would have to spend much money going to his home on a taxi, but it seemed that he wasn’t worried about that. He showed me some bikes on the side of the street. They are called shared bikes. We only need to use our mobile phones to scan the Quick-Response code (二维码) on shared bikes, and then we could ride the bikes anywhere we wanted to go. It was so cool 1．What is regarded as a “name card” for China? 2．Where did the writer buy many good and cheap things? 3．How can people use shared bikes? 4．What do you think of China’s “four great new inventions” in modern times?

Celebrated on the fourth Thursday in November in the US every year, it is a time to express your thanks to the important people and for all the good things in your life. Americans celebrate Thanksgiving with many traditions. Here we introduce several ones Americans usually follow on that day. Time for prayers (祈祷) and paying back Before the Thanksgiving meal, some families get together and say prayers to thank God for his kindness and for the gifts they have got from their friends and family members. Some people also do voluntary community work on this day—as a way of paying back. Family reunions (团聚) Like China’s Spring Festival, preparing a big meal and bringing the family together at home is a long-standing tradition of Thanksgiving. Parades bring the nation together Parades make the day a good time for the whole nation. Various parades are held in many cities. Football games as the highlight (最吸引人的地方) of the day The American National Football League has played a special game on Thanksgiving every year since its creation in 1920. Big day of discounts (打折) Like Chinese people’s shopping online on November 11, Americans also enjoy doing this just after Thanksgiving. It is quite normal to see lots of people standing in front of shops in a long line the next morning of Thanksgiving. 1．When is Thanksgiving? 2．What may be a must for Thanksgiving? 3．How many traditions do Americans usually follow on Thanksgiving? 4．What makes the day a good time for the whole nation? 5．Since when has the American National Football League played a special game on Thanksgiving? Most new babies are born in the developing countries. These countries are found in Africa, South America and parts of Asia. In the developed countries of Europe and North America, the population is growing very slowly. This is because women in these countries have, on average (平均), only one or two children. In the developing countries, many women have five or more children. In 1950, about one quarter of the world’s population lived in the developed countries. By 2050, these countries will be home to only about one tenth of the world’s people. In the developing countries, more than one billion people are still living below the poverty (贫困) line. These people do not have enough food to eat and they live in poor housing conditions. Children get little time at school and suffer (遭受痛苦) from many kinds of diseases. At the beginning of the 21st century, the world’s population was around six billion. The U.N. has said that the world’s population will level off (平稳下降) at 12.5 billion by the year 2100. Other groups think the world’s population will continue to grow, reaching 14 billion before it becomes stable (稳定的), or even falls. 根据短文内容，回答下列问题。 1．In what areas of the world can we find developing countries? 2．What was the population at the beginning of the 21st century? 3．In 1950, what percent (百分之) of the world’s population lived in the developing countries? 4．Is the population in the developed countries growing very slowly? Why? 阅读以下语篇，根据语篇内容，回答问题。 Yi Houzhang is 77 years old this year. Since 1985, he has kept doing just one thing—planting trees day after day. In 1985, to make his dream of greening the mountain near his home come true, Yi sold one cow and three pigs to buy young trees. His seven family members all worked with him, including his mother. It was difficult to plant these trees, and it was even more challenging to water them. They had to use a shoulder pole (扁担) to carry water up to the mountain. After ten years of hard work, he planted over 130 hectares (公顷) of trees, but a wildfire in 1996 burned most of his trees, and only about 20 hectares of the trees remained alive. Yi quickly restarted his work with his family. For months, they lived on the mountains so that they would have more time to plant trees. The fire taught Yi a lesson. He visited many places to learn about fire control. Later he changed the kinds of trees and built fire paths. Now, the mountain is covered with trees, and Yi has a tea garden which spreads over almost 5 hectares. He can make about 50,000 yuan a year from the garden. Though Yi’s body is growing weaker and weaker as he gets older, he goes on working with the help of his children. “When I’m unable to work, I’ll be succeeded by my children,” Yi Houzhang said. 1．How long has Yi Houzhang kept planting trees? 2．What was Yi Houzhang’s dream? 3．How did Yi and his family members water the trees? 4．What did Yi do to control the fire? 5．What do you think of Yi Houzhang? 阅读短文，简略回答问题。 Have you ever heard of e-waste (electronic waste) , which can be produced every day? Old computers, MP4 players and mobile phones can become e-waste. How do you deal with them when they’re broken or you want a new one? Most people just throw them away. With the development of electronic industry, e-waste pollution has become a serious problem. According to a survey by the United Nations in 2024, people around the world produced 62 million tons of e-waste and only recycled 13.8 million tons. China was the biggest waster, producing 14 million tons. The U.S. came second, with 7.5 million tons. It’s important to pay attention to e- waste. It can either be valuable or harmful, depending on how we deal with it. E-waste is a valuable urban (城市的) mine. Why? The value of the metals, like gold and silver in the waste around the world, is amazing. And the metals can be reused. But if people throw them away, the toxic chemicals (有毒化学物质) can get into the earth or air, influencing the environment and people’s health. Apple, for example, now recycles people’s used products in China when they are buying new ones. The company will test and repair the used ones and sell them at lower prices. To help reduce e-waste, we can also take computers and phones to see if companies offer recycling programs. 1．What can become e-waste? 2．How many tons of e-waste did people recycle? 3．Why is e-waste valuable? (回答一点即可) 4．What does Apple do when people in China want to buy new products? 5．How do your family members deal with the e-waste? 阅读短文，根据短文内容回答问题 (每题答案不超过10个词)。 Li Jia is a 16-year-old student from Nanjing No. 3 Middle School.

Do you know that many people are trying to learn a new language these days? Some of them consider it as a hobby, while others have to learn a new language because it is needed by their jobs or study. As a foreigner who is really interested in Chinese culture, I like learning Chinese. It is thought that a person needs to know at least 3,000 Chinese characters (汉字) to understand most Chinese newspapers. The problem for most foreigners, however, is that knowing 3,000 characters sounds like an impossible task. For foreigners, many Chinese characters look the same. That’s why some people give up halfway. It’s the most difficult part for me, too. But I am able to learn how to write each character by watching videos online. Whenever I saw a character I didn’t know in the street or on a menu, I would write it down and then look it up. Slowly I’ve learnt the characters that are common in daily life. As for speaking, I talk about different topics in Chinese in my daily life. It is the secret to practising speaking and helps me to think in a Chinese way. For example, whenever I am going to a shop, I would think about how to say things in Chinese. Learning a second language is never easy. But I believe that if I try my best, I can achieve my goal. 1．Why does Adam learn Chinese? 2．How many Chinese characters does a person need to know to understand most Chinese newspapers? 3．How does Adam learn to write Chinese characters? 4．What is Adam’s secret to practising speaking? 5．What does Adam think of learning a second language? My name is Jeff. I like learning foreign languages. When I retired (退休) in 2018, I could speak three foreign languages. At that time, my biggest wish was to learn a new one. Later, I watched a program about Chinese culture on TV. I was so interested in it that I made the decision to learn Chinese. I found a cultural center in the north of London by chance. It offered Chinese language courses fit for me. In March 2019, I began to learn. To attend the classes, I left my home at 5 a.m. every Saturday and drove 3 hours to the cultural center. But this didn’t stop me. After class, I practiced a lot. Through learning, I developed a love for Chinese poems and joined in activities like Chinese poetry readings. I increasingly dreamed of visiting China. My Chinese teacher Mr. Liu always mentioned “It’s better to travel ten thousand miles than to read ten thousand books”. He suggested that I should take part in a study tour in China. So in August 2024, I visited Xi’an with my classmates of the cultural center. During the trip, as the student best at Chinese among us, I tried to act as an interpreter (口译员). I helped my classmates in many ways like asking the way and shopping in Chinese. This experience encouraged me to study further. The British often say “Learning is a lifelong pursuit (追求)”, which means “It is never too late to learn”. I will keep on learning Chinese, hoping to be a lifelong learner. I believe that learning Chinese will bring even more possibilities to my life. 1．When did Jeff begin to learn Chinese?（不超过5个词） 2．Who suggested a study tour in China?（不超过10个词） 3．What do you think of Jeff?（不超过10个词） Imagine you have to take all your exams—even math exams—in English. And you have to talk to your teachers all in English! In London, lots of students do this, though English isn’t their mother language. At Southfields Community College, there are 1,300 students coming from 60 countries. They speak 71 languages. Shahid Syed, 16, comes from Pakistan (巴基斯坦). He speaks Urdu, Punjabi and a little Pashto. At school, he tries to make things easy. “We have to speak English in the classroom, so people don’t get confused (困惑的),” Shahid says. “But at home, I speak Urdu. We want to keep our own culture.” Some students spoke little English when they first arrived. Anita Sollis is a teacher at Southfields. In her opinion, the best way for students to improve their English is by listening to and speaking English in class. They learn quickly when English is everywhere around them. Sports and activities are important, too. “Sports are a great way for people to mix,” says Sollis. “It’s good for those British students, too. They can make friends with students from all over the world.” Teachers at Southfields encourage their students to learn about different cultures. Children from Italy, India, Thailand and many other countries play together. Shahid is proud of his knowledge of other cultures. “It makes you smart to know people from so many different backgrounds,” he said. 根据短文内容，回答下列问题。 1．What do you think “Urdu”, “Punjabi” and “Pashto” are? 2．Why does Shahid speak Urdu at home? 3．What is Anita Sollis? 4．In Anita Sollis’ opinion, what’s the best way for students to improve their English? 5．Do teachers at Southfields encourage their students to learn about different cultures? 请认真阅读下列短文，并根据短文内容回答问题，每题不超过10个单词。 3D printing, also known as additive manufacturing (增材制造), has been in use since 1986. Before that, 3D printing wasn’t so important. Now, however, industries have begun using additive manufacturing. 3D printing in fashion More and more people have begun using 3D printing in industries such as food and fashion. However, there has not been an active market for 3D-printed shoes for years. The possibilities with shoes may be endless. There are risks in the fashion and shoe industries when considering a long-term move to 3D printing. This would mean a change of design and production methods with a huge cost of buying new machines and materials. It is a risk without certain profit (收益), but the future of 3D-printed shoes is unbelievable because these shoes are recyclable (可回收的). It is unusual and it is a business risk. But it could be part of saving the planet from the thousands of shoes that end up in landfills (垃圾填埋场) every year. 3D printing in food Even more excellent is 3D-printed food. Beginning with a paste (糊状物) and then the printer produces shapes and designs from a computer. This process is not easy, but restaurants and food companies are still trying out the technology. At Columbia University, researchers have begun using lasers (激光) to cook the food as it prints, opening up the world of cooking. Once, they produced a piece of cheesecake in 30 minutes. While the researchers believe the technology will continue to grow and gain interest, it is currently much too expensive for people to use regularly. 1．How was 3D printing before 1986? 2．What industries have used 3D printing according to the passage? 3．Why can 3D-printed shoes save the planet? 4．How did the researchers open up the world of cooking? 5．What do you think of the future of 3D printing? 阅读下面短文，简略回答问题。 Spring is coming, and it’s time to enjoy West Lake Longjing tea!
