展开英文短文，再悬停查词
I asked an AI tool, "Why do leaves change color in autumn?" It gave me three answers. The first was too short. The second used difficult science words. The third was clear, but I was not sure it was true.
So I checked our science textbook. Then I asked the AI to explain the same idea for a junior high school student.
The new answer was better, but I still wrote the report in my own words.
AI can give hints. It cannot do my thinking for me.

读懂了什么？
读完后，试着用一句话说出本文的主要意思，并从原文找出支持它的一句话。
查看中文译文
我问一个人工智能工具：‘为什么秋天树叶会变色？’它给了三个回答。第一个太短，第二个用了难懂的科学术语。第三个讲得明白，但我不确定内容是否正确。
于是我查了科学课本，又请 AI 用适合初中生的话解释同一个问题。
新的回答更好，但报告还是由我用自己的话写成。
AI 可以提供线索，却不能替我思考。
