A good example is the four great inventions of ancient China: paper-making, compass, gunpowder and printing.Before paper was invented, people wrote on heavy bamboos and expensive silk. During the Eastern Han Dynasty, paper-making technology was improved by Cai Lun. He made the paper from cheaper materials, such as fishing nets and ropes. As a result, it became easier to make books.Before the compass was used for sailing, sailors around the world had to depend on stars to find the right direction. In the Northern Song Dynasty, the compass was then invented. It was made by putting a magnetic needle on "luopan", a wooden disk.In ancient China, gunpowder was invented by accident. At first, it was used in fireworks. At the end of the Tang Dynasty, people began to use it in wars. The technology of making gunpowder was brought to the Arabic world and Europe in the 13th century.Chinese people used block printing to produce books at first. This technology wasted many wooden boards. During the Northern Song Dynasty, Bi Sheng developed movable type printing. He made characters on special soil pieces so that they could be reused later to print other books. The invention helped spread knowledge around the world.The four great inventions were gifts from China to the world. Together they speeded up the development of human society.1. What does the passage mainly tell us?A. The history of Chinese dynasties B. The four great inventions of ancient China and their contributionsC. How paper was made in ancient China D. Why gunpowder was invented by accident2. Before paper was invented, people wrote on ________.A. silk and expensive cloth B. wooden boards and stonesC. heavy bamboos and expensive silk D. special soil pieces3. How was the compass made?A. By using heavy bamboos B. By putting a magnetic needle on a wooden diskC. By putting silk on a wooden disk D. By using fishing nets and ropes4. The underlined phrase "by accident" means ________.A. on purpose B. without planningC. in wars D. with great care5. What is the writer's viewpoint about the four great inventions?A. They were not very important to the world B. They were only useful in ancient ChinaC. They were gifts from China that speeded up human society D. They were invented by the same personPassage B — 发明故事类How Jeans Were InventedHow Jeans Were InventedJeans are one of the most popular kinds of clothing in the world today. But did you know the story behind them?In the 1850s, a young man named Levi Strauss went to California during the Gold Rush. He planned to sell cloth to make tents and covers for wagons. However, when he arrived, he found that the miners needed something more than tents — they needed strong pants.The miners' ordinary pants wore out very quickly because they worked in very hard conditions. They needed pants that were strong enough to last a long time. Levi had an idea. He used the strong cloth he had brought and made some pants. The miners loved them because they were much stronger than ordinary pants.Later, Levi decided to make the pants even stronger. He used a special kind of cloth called denim, which was brought from Nîmes, France. The word "denim" comes from "serge de Nîmes", meaning cloth from Nîmes. He also added metal rivets to the corners of the pockets to make them stronger.These pants became known as "jeans", and they were soon worn by workers all over America. Today, jeans are worn by people of all ages around the world. What started as work clothes for miners has become one of the most popular fashion items in history.This story shows that great inventions often come from solving a simple problem. Levi Strauss didn't set out to create a fashion item — he just wanted to help miners find stronger pants.6. Why did Levi Strauss go to California?A. To find gold B. To sell cloth for tents and coversC. To make jeans D. To work as a miner7. What did the miners need most?A. Tents B. GoldC. Strong pants D. Covers for wagons8. Where does the word "denim" come from?A. A city in America B. A miner's nameC. A place in France D. Levi's last name9. Why did Levi add metal rivets to the pockets?A. To make them look beautiful B. To make them strongerC. To make them cheaper D. To make them lighter10. What can we learn from Levi's story?A. Fashion is the most important thing B. Miners always need strong pantsC. Great inventions often come from solving simple problems D. France is the best place for making clothPassage C — 观点/品质类What Makes a Good Inventor?What Makes a Good Inventor?Many people think that inventors are born with special talents. However, research shows that anyone can become a good inventor if they develop the right qualities and habits.First, a good inventor is curious. They always ask questions about the world around them. They wonder why things work the way they do and how things can be improved. Curiosity leads them to explore new ideas and find solutions to problems.Second, a good inventor is creative. They can think of new and interesting ideas. Sometimes the best inventions come from looking at old problems in a new way. For example, the post-it note was created when someone thought of a new use for a "failed" glue.Third, a good inventor is persistent. Inventing something new is never easy. Most inventors fail many times before they succeed. Thomas Edison tried thousands of materials before he found the right one for the light bulb. He once said, "I have not failed. I've just found 10,000 ways that won't work."Finally, a good inventor is willing to share. Great inventions are meant to help people. If an inventor keeps their ideas to themselves, the ideas can never change the world. Sharing ideas with others can also lead to new and better inventions.These qualities — curiosity, creativity, persistence, and willingness to share — are what make a good inventor. The good news is that these are qualities that anyone can develop with practice.11. According to the passage, who can become a good inventor?A. Only people with special talents B. Anyone who develops the right qualities and habitsC. Only scientists and engineers D. Only people who went to college12. What does curiosity help inventors do?A. Make more money B. Find solutions to problemsC. Win competitions D. Get famous quickly13. How was the post-it note created?A. By following a careful plan B. By thinking of a new use for a failed glueC. By copying another invention D. By using expensive materials14. What did Edison mean by "I've just found 10,000 ways that won't work"?A. He gave up after 10,000 tries B. He was not really trying to invent anythingC. Each failure brought him closer to success D. He did not know what he was doing15. What is the main message of the last paragraph?A. Being an inventor is very difficult B. Only some people can be inventorsC. The qualities of a good inventor can be developed by anyone D. Sharing ideas is the most important qualityPart IV 词汇运用（共10小题，每小题1分，满分10分）用所给词的适当形式填空。1. Movable type printing is a ________ (tradition) Chinese printing method.2.
