时态一
提起时态,当然是指动词的时态啦。过去、现在和未来等不同时间段发生的事情要用不同的时态来表示。时态是动词的一种形式,表示动作或状态发生或存在的时间和方式。闭上眼睛想一想,初中我们学过的时态有几个? 初中我们共学过八种时态。本讲将这几个时态总体介绍一下:
  一般现在时:常与always,often,sometimes, every day连用,表示习惯或经常反复发生的动作或存在的状态。提醒你当第三人称单数做主语时,别忘了动词的变化。注意:象"地球大,月亮小"等客观真理、事实一定用一般现在时。
  现在进行时:要注意其构成:由be+动词+ing,表示说话时正在进行的动作。如:We're studying now. 我们现在正在学习。
 一般过去时:表示过去某个时间发生的动作或存在的状态,常与yesterday,last year,in 1949,two years ago,等表示过去时间的状语连用。注意:We often went to dance last summer.有的同学一见到often就想到用一般现在时,其实因为后面有表示过去时间的 last summer,所以要用过去式,千万别误用了,切记,切记。
  过去进行时:显然过去进行时表示过去某一时刻正在做什么,常和特定的时间状语如at that time,at six yesterday,at that moment,when he came in等连用。如: When he knocked at the door,his mother was cooking.
  一般将来时:表示将要发生的动作或存在的状态,常与表示将来时间状语如 next year,tomorrow等连用。注意:在Will you ....?问句中,回答必须是 Yes,I will.或 No,I won't而不能用Yes,I shall. No, I shan't.来回答过去将来时:过去将来时不可以单独使用,它一般在宾语从句中作间接引语,表示从过去某一时间看来将要发生的动作或存在的状态。如:They told me that they would go to work in Guangdong.
  现在完成时:顾名思义,现在完成时表示的是已经完成的动作,但动作造成的影响还在,常被just,already,yet 等副词修饰。如:He has already gone to Tianjin. 对现在造成的影响是他已经不在这儿了。现在完成时还可用来表示过去发生的动作一直延续到现在,常带有for或since等表示一段时间的状语。如:Mr Wang has lived here since 1983.表示说话前发生过一次或多次的动作,我们常用"过"来表示,常带有twice, once, ever, never等时间状语。如:I've never seen that film.
  过去完成时:我们可以用"过去的过去"来概括过去完成时,表示过去某一时刻或某一动作之前已经完成了的动作,通常与by,before等构成的短语或when, before, after引导的从句连用。也可表示过去某一时间开始,一直延续到过去另一时间的动作,常和for或since构成的时间状语连用。用法和现在完成时大致相同,只不过又向前推了一个时态。
 八个时态可能得让你好好对付一阵子,但细细学来,也并不困难。不信吗? 试试趁热打铁你就知道了。
