Before his invention, people carved whole pages of text onto wooden blocks, which was time-consuming and wasteful. If one character was wrong, the whole block had to be thrown away. Bi Sheng's idea was simple but revolutionary: he made individual characters out of clay, baked them hard, and arranged them on an iron plate to form pages. When the printing was done, the characters could be taken apart and reused for other pages. This made printing much faster and cheaper. At first, people didn't pay much attention to Bi Sheng's invention. But later, movable type printing spread across China and eventually to other parts of the world. It helped spread knowledge widely, making books affordable for more people. Today, we still use the basic idea of movable type in modern printing. Bi Sheng's story shows that great ideas don't have to be complicated. Sometimes, a simple change to an existing process can have a huge impact. He observed the problems with traditional printing and came up with a creative solution. His invention is a reminder that innovation is about making things better, not just making things new. 1. What was the problem with traditional printing before Bi Sheng's invention? A. It was too fast and produced too many books. B. It was time-consuming and wasteful. C. The printed books were of poor quality. D. The characters were too small to read. 2. What were Bi Sheng's movable type characters made of? A. Wood. B. Iron. C. Clay. D. Bamboo. 3. What does the underlined word “revolutionary” in Paragraph 2 probably mean? A. 传统的 B. 革命的；颠覆性的 C. 简单的 D. 浪费的 4. Why was Bi Sheng's invention important? A. It made printing faster and cheaper, spreading knowledge widely. B. It made books more expensive but of better quality. C. It was the first printing method in the world. D. It was only used by rich people. 5. What can we learn from Bi Sheng's story? A. Great ideas are always complicated and hard to understand. B. Innovation is about making things completely new, not improving old things. C. Simple creative solutions to real problems can have a huge impact. D. Only famous scientists can come up with great ideas. B Have you ever heard of the “Edible Spoon”? It's a creative invention by Narayana Peesapaty, an Indian scientist. In India, people use billions of plastic spoons every year, most of which end up in landfills or the ocean, causing serious pollution. Peesapaty wanted to solve this problem. He spent years experimenting with different materials to make a spoon that was both functional and environmentally friendly. Finally, he came up with a spoon made of millet (小米), rice and wheat flour. The spoon is hard enough to use for hot and cold food, and it tastes like a cracker. Best of all, it's 100% edible — you can eat it after using it, or it will break down in the soil within a few days if you don't. The edible spoon has become very popular in India and other countries. Many restaurants and food companies have started using it instead of plastic spoons. It has reduced plastic waste significantly and raised people's awareness of environmental protection. Peesapaty's invention is a great example of “green innovation”. It solves a real environmental problem with a simple, sustainable solution. He didn't use expensive technology or complicated processes — he just used common food materials in a new way. His story shows that creative ideas can come from everyday materials, and even small changes can make a big difference to the planet. 6. Why did Narayana Peesapaty invent the edible spoon? A. Because he wanted to make a new type of food. B. Because he wanted to reduce plastic pollution. C. Because he wanted to make money from selling spoons. D. Because he wanted to win a science award. 7. What is the edible spoon made of? A. Plastic and millet. B. Millet, rice and wheat flour. C. Wood and clay. D. Paper and glue. 8. What does the underlined word “functional” in Paragraph 2 probably mean? A. 可食用的 B. 环保的 C. 实用的；可用的 D. 美味的 9. What is the main advantage of the edible spoon? A. It is more expensive than plastic spoons. B. It takes years to break down in the soil. C. It is edible and environmentally friendly. D. It can only be used for cold food. 10. What is the main idea of the passage? A. The history of plastic spoons in India. B. A creative green invention that helps reduce plastic pollution. C. How to make edible spoons at home. D. The importance of eating healthy food. 四、读写综合 A. 回答问题 阅读上面B篇关于可食用勺子的短文，回答下列问题。 1. Who invented the edible spoon? 2. What problem did the inventor want to solve? 3.
