2015年GCT考试英语备考辅导:时态和特殊用法

2014-02-24 14:05:12来源:233网校

  四、现在完成进行时

  现在完成进行时表示动作从过去某一时间开始,一直延续到现在,可能还要继续下去,通常与表示一段时间的状语连用。如: All the morning,for hours,since this morning… / They have been watching television for two hours. / He has been writing letters since this morning.

  五、 过去完成时

  1、过去完成时,表示在过去某一时刻或动作以前已经完成的动作。即”过去的过去”。常用的信号词有by(到……时候为止),before等介词短语,或用 unless,when,after,once,as soon as等连词引起的表示到过去某一时间为止的时间状语来表示。

  2、过去完成时常用在”no sooner…than”,和”hardly…when (before)”等句型的主句中,从句中常用一般过去时。如:By the end of last year,I had worked in this college for ten years. / No sooner had he finished his performance than the audience began to cheer. (=He had no sooner…than…) (他刚表演完观众就喝采)

  六、其它要注意的时态

  1、be going to口语中常用,表示最近打箅要做的事情;根据某种迹象表明可能要发生的事情。如:What are you going to do this evening? / Look at the cloud. It is going to rain.

  2、过去将来时,多见于主句谓语动足一般过去时的宾语从句中。如:He said that he would get married soon.

  3、过去进行时主要用法之一是描述一件事发生的背景,往往在一个动作发生的过程中,突然发生第二个戏剧性的动作。第二个戏剧性动作为一般过去时,由 when或while引出,意为”此时”。有二种句型:My pother fell while he was riding his bicycle and hurt himself. / Tom slipped into the house when no one was looking. / Someone knocked at the door while I was taking a shower. / Just as I was opening the door,the telephone rang.

  4、如果两个动作都引人注目且同时发生,并没有一个比另一个更形象、更主要时,那么两个动作都可以用过去进行时。如:My husband was reading while I was cooking.

  七、有些动词以主动形式出现,却有被动含义

  如:The knife cuts well. / Nylon underwear washes easily. 尼龙内衣容易洗 / The novels written by the young man sell well.那个年青人写的小说销路好 / This ball-pen writes in four colours. 这支园珠笔可以写出四种颜色 / The note reads as follows”…”. 字条上写着:”……”。

  八、短语动词构成的被动语态中,介词或副词不可省略

  如:More schools and hospitals will be set up in the near future. / The old woman has been operated on. (这位老妇人已经动过了手术) / The purse was picked up and handed to the police. 此外,固定搭配 “动词 + 名词 + 介词” 习语中,介词也不能省掉。 Time must be made good use of. / Less clever children should not be made fun of.
