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：Were 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 wont而不能用Yes,I shall. No, I shant.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：Ive 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。
