The bottle is made of soft, food-grade silicone (硅胶). When it is full of water, it stands upright like a normal bottle. But when it is empty, you can roll it up or fold it into a small size, making it easy to carry in your pocket or backpack. The idea came from a young engineer named Mike, who loved hiking but hated carrying heavy water bottles. One day, he saw a toothpaste tube and thought, "Why can't a water bottle be like this?" After two years of hard work, he finally created the first foldable water bottle. The bottle is not only convenient but also environmentally friendly. It can be reused thousands of times, which helps reduce plastic waste. Many outdoor lovers say it has changed the way they travel. "I used to buy plastic bottles during my trips, but now I just carry this one. It saves money and protects the environment," said a user. However, some people worry that the silicone material might not be as safe as hard plastic. Mike's team has done many tests to prove that their product is completely safe and meets all health standards. They are now working on new designs with different colours and sizes. 1. What is the "Foldable Water Bottle" made of? A. Hard plastic. B. Soft silicone. C. Glass. D. Metal. 2. Where did Mike get the idea for his invention? A. From a hiking trip. B. From a toothpaste tube. C. From a science book. D. From his engineering teacher. 3. What does the underlined word "reused" probably mean in Chinese? A. 回收 B. 重复使用 C. 制造 D. 出售 4. What is the main advantage of the foldable water bottle according to the passage? A. It is cheaper than normal bottles. B. It can keep water hot for a long time. C. It is convenient to carry and environmentally friendly. D. It can change colour when the water is cold. 5. 创新考法·写作意图 What is the writer's purpose in writing this passage? A.
