不定式可以做哪些句子成分

Question

如题所述

Answer 1

答：
我们可以从下列句子中来判断：
1. I want to sleep. 我想睡觉了。（作want的宾语）
2. To think is only the begining of an action. 思考仅是行动的开始。（作句子的主语）
3. To succedd is to work hard. (前者做主语，后者做表语)
4. The girl to sing the song is Mary. (作后置定语)
5. To succeed, one must work hard. (作整个句子的状语)
6. I am here to help (作目的状语)
7. They are not strong enough to fight the enemy. （作补语）
8. I asked him to help me with my homework. （做补语）
注：状语和补语的区别在于：状语去掉不影响句子意思的完整性，而补语去掉则不行。如第8句：去掉to help me后句子则不完整了。
