阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项。
A
Papermaking is one of the greatest inventions in Chinese history. Before paper was invented, people wrote on bamboo, wood, and silk. These materials were heavy or expensive. In 105 CE, Cai Lun, an official in the Han Dynasty, improved the papermaking process. He used tree bark, old cloth, and fishing nets. These materials were cut, boiled, and then beaten into a soft pulp. The pulp was spread on a screen to dry. The result was a thin, light, and cheap material that was suitable for writing. Later on, papermaking spread to other countries. It was responsible for the rapid spread of knowledge and culture around the world. Today, paper is used everywhere—in books, newspapers, and offices. Even in the digital age, paper remains an important part of our lives.

The invention of the plane has greatly changed the world. However, it seems that its inventors, Orville Wright and Wilbur Wright, were not looking to change the world at all. To solve the problem of heavier-than-air flight, the Wright brothers began working with gliders. There were two main challenges. The first was how to get the glider into the air. The second was how to control it once it was flying. For both problems, they found their solution by looking at how birds flew. They spent hours watching birds and studying their wings. After they solved these problems, they added an engine to the glider. Then, in December 1903, the world's first plane flights were made. The plane was not invented by one person alone. It was the result of careful observation, repeated experiments, and the courage to try something new.

The 3D printer is a modern invention that is changing the way we make things. The idea first appeared in science fiction in the 1940s and 1950s. People wanted to print real objects, so the first 3D printer was invented in the USA in 1983. A 3D printer works by building objects layer by layer. Almost everything under the sun can be made by a 3D printer. It can be used for making life-size models of car parts, and even man-made body parts such as ears. In the future, doctors may use 3D printers to create organs for patients who need them. This could save many lives. As we move into the future, 3D printing will change the way we make things and the way we treat sick people. It is a good example of how an idea from science fiction can be turned into reality.

A. In 1983. B. In the 1940s and 1950s. C. In 2000. D. In 1903.

D
How do great ideas come to people's minds? This is a question that many people ask. I believe that curiosity is the start. When you see a problem, ask yourself: “How can I make this better?” Then, you need to reflect on the problem. Think about it from different angles. Next, you should come up with as many solutions as possible. Don't be afraid to think outside the box. For example, if you want to improve your school, you might think of ways to make it cleaner, safer, or more fun. After that, you need to try out your ideas. Some of them will fail. But failure is not the end. It is a chance to learn. As the saying goes, “The more you try out new ideas, the more creative you will become.” Finally, you should keep an open mind. Listen to others' opinions. What matters is not success but the process.
16. What is the start of a great idea according to the passage?
A. Money. B. Curiosity. C. Luck. D. Fame.
17. What should you do after you see a problem?
A. Give up.
B. Ask how you can make it better.
C. Wait for others to solve it.
D. Forget about it.
18. What does “think outside the box” mean?
A. Think in a normal way.
B. Break free from usual thinking.
C. Stay inside a box.
D. Copy others' ideas.
19. What does the writer say about failure?
A. Failure is the end.
B. Failure is useless.
C. Failure is a chance to learn.
D. Failure should be avoided at all costs.
20. What is the main idea of the passage?
A. How to become famous.
B. How great ideas come to people's minds.
C. Why failure is bad.
D. How to make money.

The Power of Ideas
Last month, I came up with an idea to start a “Question Wall” in our classroom. I noticed that many classmates were afraid to ask questions. I shared my idea with my teacher. She said it was a good idea. We put a big board on the wall. Students could write questions on sticky notes. Every Friday, we discussed the questions together. Now everyone feels safer to ask. I learned that a small idea can make a difference.

第一节（共20小题；每小题1.5分，满分30分）
阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项。
A
The compass is one of the most important inventions in Chinese history. Before the compass was invented, sailors had to rely on the sun, the moon, and the stars to find their way. But on cloudy days, they could easily get lost. The earliest compass was made of lodestone, a natural magnetic material. It was first used during the Warring States period.
Later, during the Song Dynasty, the compass was improved and used for sea navigation. This invention made it possible for Chinese sailors to travel to faraway places such as Africa and the Middle East. It was also responsible for the development of global trade and cultural exchange. Without the compass, the great voyages of exploration in the 15th and 16th centuries might not have been possible. Today, the compass is still used by hikers, sailors, and explorers. It reminds us that a simple idea can change the world.
1. What did sailors rely on before the compass was invented?
A. Only the sun. B. The sun, the moon, and the stars.
C. Only the moon. D. Maps and GPS.
2. What was the earliest compass made of?
A. Iron. B. Lodestone. C. Copper. D. Steel.
3. When was the compass used for sea navigation?
A. During the Warring States period.

Biomimicry is the practice of learning from nature to solve human problems. For example, the idea for Velcro came from a walk in the woods. George de Mestral, a Swiss engineer, noticed that burrs stuck to his dog's fur. He looked at the burrs under a microscope and saw tiny hooks. He wondered if he could create a fastener that worked the same way. After many experiments, he invented Velcro. Another example is the bullet train. Its nose was designed to look like a kingfisher's beak. This design helped the train move faster and more quietly. Scientists also study lotus leaves to create self-cleaning surfaces. Biomimicry shows us that the best ideas may already exist in nature. We just need to observe carefully and ask questions. As the saying goes, “Nature is the best teacher.”
