But in space, food cannot be grown easily, and fresh food goes bad quickly. To solve this problem, scientists are developing 3D food printers for space stations. These printers work like normal 3D printers, but instead of plastic, they print food. The food comes in dry powder (粉末) form. When the printer gets the order, it mixes the powder with water and oil, then prints it layer by layer into a shape, like a pizza or a cookie. The biggest advantage of this technology is that it reduces waste. The powder can be kept for years without going bad. Also, the printer itself is small and light, which saves space on the spaceship. Most importantly, the food can be personalized (个性化定制). If an astronaut wants more protein or vitamins, the printer can change the recipe (食谱) automatically. Although 3D food printing is still new, it is a big step forward. It might not only change how astronauts eat but also help solve hunger problems on Earth in the future. 21. Why is it hard to eat fresh food in space? (不超过10个词) 22. What does the 3D food printer use to print food? (不超过10个词) 23. What is the biggest advantage of 3D food printing in space? (不超过10个词) 【参考答案及解析】 Ⅰ. 单词拼写 1. benefits (many 修饰复数名词) 2. resources (natural resources 自然资源) 3. operate (how to 后接动词原形) 4. universe (宇宙) 5. useful (be 动词后接形容词) Ⅱ. 完成句子 6. may be able to (也许能够) 7. can be recycled (情态动词被动：can be done) 8. plenty of / a lot of (大量的) 9. can clean up (净化：clean up；情态动词后接原形) 10. will be a good place (一般将来时；仿写句式：It will be a good place for sb. to do sth.) Ⅲ. 完形填空 11. D (problems与solve是被动关系，且by then表示将来，用将来时被动) 12. A (necessity 必要性，因为资源减少，住到太空变成一种必要) 13. D (cities与build是被动关系，且是将来的事，用将来时被动) 14. C (wheel与rotate是主动关系，且表示将来的状态，用will rotate) 15.
