动词不定式用法例句 :动词不定式6种用法
动词不定式6种用法:
1、不定式的一般式:动词不定式一般式即to+动词原形。
所表示的动作是和谓语动词所表示的动作同时发生,但在多数情况下,是在谓语动词所表示的动作之后发生,不定时一般式与句子主语、宾语或forsbtodosth。结构中的介词宾语有逻辑上的主谓关系。
2、不定式的完成式:即tohave+过去分词。
动词不定式完成式所表示的动作发生在谓语动词所表示的动作之前,它的逻辑主语也是句子的主语或宾语。
3、不定式的进行式:tobe+现在分词。
动词不定式进行式所表示的动作正在进行中,而且与谓语动词所表示的动作同时发生。
4、不定式的否定式:动词不定式的否定式是由not+动词不定式构成。
5、不定式的被动式:当不定时的被动式逻辑主语是不定式所表示的动作的承受者时,用不定时的被动形式,即tobedone或tohavebeendone。
6、to代替整个不定式:如果句子前面出现过同样的动词,为避免重复,句子后边的不定式应省略动词原形及其后续部分,只保留不定式的符号to。
