e. He arrived at the station, only to find the train had left.
三.使用动词不定式时应注意的问题:
1.动词不定式省略符号to的情况:
①.在感官动词和使役动词后作宾补的不定式省略to(参看上文)
②.在一些固定结构中,.动词不定式省略to, 如: rather than do sth, would rather do sth, had better do sth, why not do sth.
a. Rather than ride on a crowed bus, he always prefers a bicycle.
b. Why not go out for a walk ?
c. I would rather play football than basketball.
③.当两个并列的带to的不定式由and或or连接时, 第二个不定式的符号to可以省略
a. I intend to call on him and discuss the question again.
b. She asked you to call or write to her on Sunday.
c. I havent decided to go home or to stay at school this summer.
2.动词不定式位于某些形容词之后, 构成以下句型: S + be + adj. + to do. 在此句型中, 句子主语与不定式动词do有两种关系:
①.句子主语与不定式动词是逻辑主谓关系
a. They were eager to know everything about China.
b. I am sorry to keep you waiting.
②.句子主语与不定式动词是逻辑动宾关系, 这时, 如果不定式动词是不及物, 则需加上适当的介词
