干货！种种测验相对用得上的“非谓语动词”剖析—动词不定式

考点点拨

动词不定式由“to + 动词本相”构成，在句中可作主语、宾语、宾语补足语、表语、定语、状语等。其否定情势是“not to + 动词本相”。

动词不定式作主语时，为坚持句子均衡，常用it充任情势主语，而将不定式主语放在后方。

动词want, refuse, forget, agree, hope, decide, fail, promise, hope等后可跟动词不定式作宾语。

“疑问词 + 动词不定式”是动词不定式的复合布局，常用作consider, decide, discuss, forget, know, remember, wonder, find out等动词(短语)的宾语。

当动词不定式作宾语且自后有补语时，常用it作情势宾语，而将真正的宾语放在后方。

动词allow, advise, ask, tell, invite, expect, encourage, order, (would) like等后常跟动词不定式作宾语补足语。

make, let, have等使役动词和feel, see, hear, watch, notice等感官动词后常跟不带to的动词不定式作宾语补足语。

动词不定式作定语时，常置于被修饰词之后。

动词不定式作状语时，可以用来表现目标或后果等。
