动词不定式可以用作目的状语来表达一个动作的目的或意图。它通常是由 "to" 加上动词原形构成。以下是几个例子:
- He went to the store to buy some groceries.(他去商店买一些食品杂货。)
- She studies hard to pass the exam.(她努力学习以便通过考试。)
- They traveled to Italy to experience the culture.(他们去意大利旅行以体验文化。)
- We exercise regularly to stay healthy.(我们经常锻炼身体以保持健康。)
在这些例子中,不定式短语 "to buy some groceries"、"to pass the exam"、"to experience the culture" 和 "to stay healthy" 都说明了主语进行相应动作的目的或意图。
