B In recent years, Chinese printing companies have drawn people's attention due to their rapid growth and great achievements. How-ever, China's achievements in printing were not made overnight. A long time ago, if people wanted a new book, they had to copy all the characters by hand. But in China, during the Sui and Tang Dynasties, people found a way to print faster. They would carve (刻) the characters into the wooden blocks, put ink (墨水) on the characters, and then press paper onto the wooden blocks to create a copy. This was faster, but it took a long time to make the blocks and fix mistakes. Later, during the Northern Song Dynasty, Bi Sheng invented movable-type printing. He carved characters on small pieces of clay and heated them until they became hard movable characters. They could be repeatedly used for the type-setting and printing of different printed forms. This method was both economical and time-saving. It cost less than copying with the blocks. After that, people started using other materials for these movable characters until the birth of the electronic composing (排版) system. The invention then spread all over the world. In modern society, printing plays an important role in spreading information and knowledge and serves different purposes. Printed materials for marketing, books and newspapers are all examples. 6.What is the advantage of printing by using the wooden blocks? A. It's easy to fix mistakes. B. It's much too cheap. C.

Importance of wood carving in printing. 8.What does the underlined word “economical” in Paragraph 3 most probably mean? A. Not having many resources. B. To use less space than is necessary. C.

D. It greatly sped up the exchanges of cultures of all countries around the world. 10.What is the structure of the text? (P= Paragraph) A. B. C. D. C Have you ever imagined that your ordinary T-shirt can act as an air conditioner on hot summer days? Thanks to a recent discovery, that possibility is getting closer, and such T-shirts may soon be sold by your favourite clothing brands(品牌). Two inventors used a completely new method. They designed a special textile(纺织品) that can take in body heat and then send out the energy. This new textile cools both the wearer and nearby objects with special technology. This means that a T-shirt made of this textile looks like an ordinary T-shirt, but actually it is a device that works like a mirror. Although the technology is not new and has been used for years to design plastic films and special paints, its use in the textile industry for the benefit of wearers is very special and exciting. That is because, in the past, the methods we used to deal with heat through clothes were only simple suggestions for wearing light colours and choosing breathable textiles. But even when these suggestions may actually help you feel cool, they are simply not enough in the hottest season. The new textile, however, can reflect sunlight and body heat, and this can contribute to the cooling process. So this discovery is a real advance. Right now, researchers still need to test the new method to know how well the new textile works when wearers stand, walk, or do not face the sky directly. They also need to test how well it works when T-shirts are not close to the skin. But it's still a great success. The two inventors are now looking for clothing brands that are interested in using their textile. One inventor said,“The new material will increase clothing production costs by just 10 percent. We can produce it on a large scale. Most people can afford a T-shirt made of this textile, and its price is almost the same as that of an ordinary T-shirt. It is good for everybody.” 11.What can the new textile do? A. Make wearers feel cool. B. Make wearers fashionable. C. Get wearers' health information. D. Test wearers' body temperatures. 12.What does the underlined word “breathable” most probably mean in the third paragraph? A. Being very light in weight. B. Being able to produce cold air. C. Making the wearer breathe faster. D. Allowing air to pass through easily. 13.What can we infer about the new textile from the text? A. It was invented a long time ago but never tested. B. Producing it costs more than an ordinary T-shirt. C. Its cooling effect may change in different situations. D. It has been widely used in clothing brands around the world. 14.What are the two inventors doing now? A. They are making money by selling the textile. B. They are trying to use the textile in other fields. C. They are trying to find out more secrets of the textile. D. They are looking for clothing brands to use the textile. 15.What's the best title for the text? A. The Future of Air Conditioners B. A Cool T-shirt for Hot Summer Days C. How to Choose Summer Clothes Wisely D.

However, in ancient times, people had to walk everywhere or drag heavy loads on the ground. Life was very difficult until the wheel (37) (change) everything. The wheel is considered one of the most important (38) (invent) in history. It appeared around 3500 BC. Before the wheel, transporting building (39) (material) like stones and wood took a long time and required many people. With the help of carts and wagons, people could move heavy things much more (40) (easy). This invention (41) (total) changed the way people lived. It helped farmers carry their crops to markets in other towns. As a result, trade developed (42) (rapid), and the local economy began to grow. Over time, villages turned into cities. The wheel was not just (43) (use) for transport. It was also used in war to make chariots(战车)faster. Today,wheels are everywhere.

Without this simple round object, modern society would come to a (45) (completely)stop. Its potential continues to be used in new technology today. It is truly a surprising invention that keeps the world moving. 五、任务型阅读(5小题,共10分) A 2025 report from the World Health Organization points out a big problem: nearly half of the people around the world who need mental(心理上的) health support can't get it. This is largely because many people cannot afford to see a mental health professional, and there are not enough trained experts to meet the need. Now, AI chatbots(聊天机器人) are becoming a new choice for people to get help. People can talk with chatbots about their problems at any time, and using them is much cheaper than traditional ways. Doctors also believe AI has its advantages. Dr Li from Beijing Hospital says,“Chatbots can help deal with daily stress. Users often feel that they are being listened to.” This is especially helpful for those who feel lonely or stressed. However, most people agree that AI cannot take the place of human doctors. They believe that human beings understand our feelings much better because they have true emotions. The human connection is very important for treatment. Another problem is that we can't always trust AI's answers. Human doctors receive years of training to learn the right way to help people. AI does not have this real-world experience. So, experts say that our government needs to make strict rules to make sure AI works properly. In the future, AI is expected to work together with human doctors to provide better mental health care for everyone. In this way, more people can get the help they need. 46. Is it cheap or expensive to see a mental health professional? 47.When can people talk with AI chatbots about their problems? 48.Who might find AI chatbots especially helpful? 49.What is very important in mental health treatment? 50.How can our government make sure AI works properly? 六、书面表达(1小题,共20分) 现如今,我国科技正飞速发展。某青少年网站“Inventions”专栏开展了征文活动。请你根据以下要点,用英语写一篇短文,向该专栏投稿。 写作要点: (1)What invention do you use most often?

Among these inventions, I use the clock the most. The clock wakes me up every morning and it also reminds me to make the most of my time. Owning a clock might seem easy, but putting it to good use requires some effort. To begin with, we can set a clock for our to-do lists so that we won t put off anything. Moreover, clocks can help us manage time. For example, we can set a limit of half an hour on using the computer. Last but not least, clocks can also be used to track how much time we spend on a certain thing, like completing a paper. In a word, the clock is a useful invention that can help us stay organized and manage time wisely. So let s make the most of it! 第1页,共1页 学科网(北京)股份有限公司 $
