定义 / 说明
我们常用 to + verb 表示动作目的。它能简洁回答“为什么？”例如 I went out to buy bread，意思是“出去”的目的就是“买面包”。这个结构在日常英语中很常见，通常比 in order to 一类长表达更自然。它应表达“目的”，而不是时间上的“下一步动作”。
关键规则
- 结构：to + base verb。
- 用于回答 Why?
- 常放在移动类动词后：go out to buy bread。
- 也可放在其他动作后：call to ask, sit down to rest。
- 该结构不要用 for + verb。
例句
- I went out to buy bread. - 我出去买面包。
- She called to ask a question. - 她打电话来问一个问题。
- We stopped to rest. - 我们停下来休息。
- He is saving money to travel. - 他在存钱去旅行。
- I came here to help you. - 我来这里是为了帮你。

- ❌ She called for ask a question. -> ✅ She called to ask a question.
