⑤ 动词不定式可以在句子中用作定语,放在名词或代词后面。

[A] 记住下面的一些结构：

[B] 在这种情况下,如果不定式动词是不及物动词,则后面必须加介词。如：

They could not find a place to live in.(他们找不到住的地方)/ Please give me a chair to sit on.(请给我一张椅子坐坐)/ He has got a writing brush to write with.((他找到了写字的毛笔)

⑥ 动词不定式可以在句子中用作状语,有下列几种情况：

[A] 放在不及物动词(come, go, stop, finish, wait等词)的后面。如：He came to see her yesterday.(他昨天来看望她)(表示来的目的)/ I stopped to have a rest.(我停下来休息一会儿)(表示停下来的目的)

[B] 放在完整的谓语之后(即“谓语+宾语”、“谓语+宾语+补语”、“动词+表语”之后)。如：We cleaned the room to let him play in it.(我们打扫了房间以便让他在里面玩)/ I opened the window to see more clearly.(我打开窗子以便看得更清楚点儿)

[C] 有时表示目的的不定式短语可以放在句首。如：To arrive there on time,I got up one hour earlier than usual.(为了按时到达,我们比平时早起了一个小时)(表示早起的目的)

[注意] stop to do 与stop doing的不同。如：They stopped to have a look.(他们停下来看看)(不定式作“停下来”的目的状语)/ They stopped looking out of the window and began to listen to the teahcher.(他们停止向窗外望,开始听老师讲课)(动名词作宾语,表示“停止”的内容)
