考研英语语法语态解析大全

  动词不定式一般式所表示的时间关系

考研英语语法语态解析大全

  1)动词不定式一般式表示的动作与谓语动词表示的动作同时发生,考研英语:语法大全(动词不定式语态用法)。如:

  I saw him go out.我看见他出去了。(saw与go out两个动作同时发生)

  Would you help me put things in order before we leave?在我们离开之前,你帮我整理一下东西好吗?(would help和put同时发生)

  2)但在很多情况下,动词不定式一般式表示的动作发生在谓语动词表示的动作之后;如:

  I hope to see you again.我希望再见到你。(to see这个动作发生在hope之后)

  The boy said he wanted to be a scientist.这男孩说他想做一个科学家。(to be在wanted之后)

  动词不定式的时态形式

  动词不定式通常有三种时态形式,现以write为例:

  一般式to write进行式to be writing

  完成式to have written

  动词不定式完成式的用法

  动词不定式完成式表示的动作发生在限定动词表示的动作之前。如:

  I am sorry to have kept you waiting.对不起,叫你久等了。(to have kept发生在am所表示的.时间之前)

  She seems to have read the book before.她好像看过这本书。(to have read发生在seems所表示的时间之前)

  The battery appears to have run down.这组电池好像已经用完了。(to have run down发生在appears所表示的时间之前)

  但在下面句子中,动词不定式表示“动作没有完成”:

  We were to have met at ten.我们本来是约定十点钟见面的,考研英语《考研英语:语法大全(动词不定式语态用法)》。(结果未见面)

  动词不定式进行式的用法

  动词不定式进行式表示动作正在进行,与谓语动词表示的动作同时发生。如:

  When he came in,I happened to be lying on the bed,reading.他进来的时候,我碰巧正躺在床上看书。

  动词不定式的被动语态

  动词不定式有两种被动语态形式:

  一般式to be written

  完成式to have been written

  例:

  The next thing to be done is to carry away the earth.下-步要做的事是把土运走。

  No harm seems to have been done.似乎并没有造成损害。

  分裂不定式

  有时在不定式符号“to”和动词原形之间插入一个副词,这种现象叫做分裂不定式(split infinitive)。插入动词不定式的副词,习惯上往往与不定式动词连在一起。如:

  He likes to half close his eyes.他喜欢半闭着眼睛。

  Our object is to further cement friendly relations between the two countries.我们的目的是进一步加强两国之间的友好关系。

  At first he wasn't interested in bookkeeping,but later he began to actually like it.起初他对会计工作没有兴趣,但到后来倒喜欢起它来了
