That all changed when I visited a nature reserve with my science teacher last summer. There, I saw a Venus flytrap for the first time. When a fly landed on its leaves, the trap closed quickly and caught the insect. I was shocked—plants could act like animals! The guide told us that the flytrap grows in poor soil, so it has to catch insects to get enough nutrients. It has adapted to its environment in such a clever way. Listening to the guide and watching the flytrap, I felt ashamed for thinking plants were uninteresting. I realized that every living thing has its own amazing way to survive. By the time I left the reserve, I had made a promise: I would join the school’s plant protection club and learn more about the wonderful world of plants. This experience didn’t just make me love plants; it taught me to respect all forms of life. Whenever I see a plant now, I stop to think about its hidden secrets. It reminds me that nature is full of surprises, and we should always keep an open mind to learn from it. 任务一：根据短文内容选择正确答案 1. When did the writer first see a Venus flytrap? ( ) A. When he was 10 B.
