Ordinary people can also produce great creations as long as they keep trying. Creative ideas stay in our minds until we take action. 2. Workers in old workshops would test different materials, such as bamboo, bark and bronze. Some materials melt under heat, while others become sticky when cooled. They kept trying until they found something suitable for reallife use. Papermaking is a good example. Before paper was invented, writing materials were either heavy or too expensive for common people. 3. Gradually, newkind paper was produced. It was cheap and light. Soon it spread around the world and helped people gain much knowledge. 4. Plastic is super convenient, yet its wide use results in serious pollution. None of the inventions is completely perfect. 5. We are supposed to be responsible for how we use these powerful creations. A. Not all inventions bring only good sides. B. But that is not completely true. C. People spent plenty of time testing new materials. D. So we should treat every new invention with careful thinking. E. People hoped to turn their creative thoughts into reality. B篇 主题:Modern inventions change tourism and daily life 阅读短文,从 AE 中选出最佳选项填入文中空白处。 Modern inventions shape our modern world in many ways. 1. Highspeed trains are one of the most famous modern creations. Thanks to the rapid development of transport, longdistance trips become much easier. 2. Tourism gains a lot from this great invention. More visitors can afford to travel to faraway places. Besides transportation, small everyday inventions also make a difference. The 3Dprinter is popular in many workshops. 3. You press a button, and it can create small models in seconds. Some objects are made of plastic; others use liquid materials. However, new technology also brings new challenges. Plastic waste is one serious problem. 4. It is believed that everyone should play a part in solving it. Inventions do not decide everything. 5. Only good use can bring us a better future. A. It works fast and produces specialshaped objects. B. Our choices and actions decide how inventions influence us. C. They have a big effect on both travel and daily life. D. More people choose to take trips across the country. E.

Paper‑making is one of the greatest ancient Chinese creations. It helped the rapid spread of information and shaped the modern world. Before paper was invented, ancient Chinese wrote on bamboo slips, bronze pieces or silk. Bamboo was heavy and difficult to store. Bronze was hard to produce. Silk was beautiful but too expensive for common people to afford. Few suitable materials were for wide‑range writing. In Eastern Han Dynasty, Cai Lun worked in palace workshops. He tried many different materials: tree bark, old cloth, bamboo. He mixed, boiled and dried them. Gradually, a new kind of paper was created. It was cheap and light. Soon the great invention spread around the world. However, paper‑making also brought new problems. Large‑scale paper production needs plenty of wood. Cutting too many trees may result in environmental trouble. So human beings are responsible for balancing production and environmental protection. Creative ideas can turn into reality, but we must think about their influence. 根据短文内容,选择最佳答案。 1. What writing technique does Paragraph 2 mainly use? A. By listing numbers B. By comparing materials C. By telling a story D. By asking questions 2. What can we know from the passage? A. Silk was cheap for most ancient people. B. Cai Lun created paper only from wood. C. Paper‑making has both advantages and problems. D. Paper spread slowly because it was too heavy. 3. What is the main idea of Paragraph 4? A. The steps of making ancient paper. B. The environmental influence of paper‑making. C. Different kinds of ancient writing materials. D. How paper changed ancient people’s life. 4. Which is the best title for the text? A. The History and Influence of Paper‑making B. Great Inventions in Eastern Han Dynasty C. How to protect our environment D. Materials used for ancient writing D篇 主题:3Dprinter: Modern Creation Changes Daily Life Creative ideas can turn into reality with modern technology. The 3Dprinter is such a great modern invention. It is now widely used in many workshops all over the world. If you press a button on a 3Dprinter, it can build small objects in seconds. Some objects are made of plastic. Others are produced from liquid materials. When liquid material cools down, it will freeze into solid shapes. 3Dprinters are suitable for making small models, toys and useful parts. They help people gain new experience in designing things. Yet none of inventions are perfect. Plastic is widely used for 3Dprinting. Bad management of plastic waste may result in serious pollution. Though 3Dprinters bring convenience, they also cause new challenges. It is believed that technology itself does not solve problems. People, as users, are responsible for how we use these creations. We should make good use of creative power instead of only enjoying its convenience. 根据短文内容,选择最佳答案。 1.What is the structure of the passage? A. ①总起;②介绍发明特点;③讲缺点;④总结观点 B. ①②时间顺序;③④并列举例 C. ①③全部举例;④得出结论 D. 问题 — 提出方案 — 成功案例 2.How does the writer introduce the 3Dprinter in Paragraph 2? A. By giving examples of its working process B. By listing different opinions from users C. By comparing it with old printers D. By studying survey results 3.Which of the following is TRUE according to the text? A. 3Dprinter can only work with plastic materials. B. Objects from 3Dprinter need hours to finish. C. Liquid materials can become hard after cooling. D. 3Dprinters are seldom used in workshops now. 4.What is the main idea of the whole text? A. Different materials for 3Dprinting B. 3Dprinter: invention with advantages and challenges C. Why plastic causes worldwide pollution D. How creative ideas come into people’s minds 5.What does the writer want to tell us? A. We should stop using 3Dprinters right away. B. Every invention can solve all kinds of problems. C. People are responsible for the use of new creations. D. We must invent more new hightech machines. 三.完成句子(根据句子的意思,完成句子) 1. 这项伟大的发明在全世界被广泛使用。 This great invention all over the world. 2. 这座雕像由青铜制成,你可以看见原材料。 This statue bronze.
