1、Unit7 Time and actionStructure in use and grammar in useLearning Plan英语中不同时间和方式发生的动作或状态要用谓语动词的不同形式来表示，这种表示动作或状态发生时间和方式的动词形式称作动词时态。时间主要有四个主要部分，即现在、过去、将来和过去将来。动作方面也有四种，即一般、完成、进行和完成进行。中学课本中常见的时态有以下几种：时态构成用法一般现在时主语动词(单数第三人称 s或es)表示现在的特征、状态、经常性动作或客观事实等现在进行时主语 am (is，are)现在分词表示说话时正在进行的动作或现阶段正在进行的动作现在将来时(1
2、)主语will(shall)动词原形(2)主语 am (is, are) going to 动词原形表示在现在看来将要发生的动作或存在的状态现在完成时主语have (has)过去分词(1)动作发生于过去，一直持续到现在，可以和表示持续性的时间状语连用。(2)动作发生于过去，已经完成，但这个动作对现在有影响，一般没有明显的时间状语，主要通过上下文来理解。时态构成用法一般过去时主语动词的过去式表示过去某时发生动作(包括过去习惯性的动作)或存在的状态过去进行时主语 was (were)现在分词表示过去某个时间正在进行的动作过去将来时主语 would 动词原形表示从过去某个时间看来将要发生的动作或存在
3、的状态过去完成时主语 had 过去分词既可以表示在过去某一个时间或动作之前就发生或完成的动作，也可表示过去发生的某一动作一直持续到过去的另一个时间或动作。现在完成进行时主语have (has) been 现在分词现在完成进行时表示从过去某一时间开始一直延续到现在的动作。现在这个动作可能刚刚终止，也可能仍在进行。一、choose the best best answer1.If he _at home, Ill let you know.
