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。
