(二)一般过去时
1.一般过去时表示过去某一时间发生的动作或情况。

I didn’t expect you were waiting for us. 我没预料到你正在等我们。
一般过去时的被动语态:主语+was / were +done

(三)一般将来时

②在条件状语从句和时间状语从句中用一般现在时表将来。
If you leave tomorrow , I’ll see you at the airport. 如果你明天走,我到机场送你。
(2)现在进行时表将来
现在进行时表示将来,往往是指计划好或准备要做的事。一些表示动作转换的终止性动词,如go, come, leave, start, begin,stay,take off,arrive等,或者也称为位移性动词,其进行时表示马上要做某事。
He is leaving school in one year’s time.他一年后就要毕业了。
(3)be about to do. 结构表示“刚要做某事,马上要做某事,正要做某事”,强调动作即将发生(不跟表将来的时间状语连用)。
They were about to leave when the telephone rang. 他们正要离开时电话响了。
(4)be going to常用于口语中,表示“计划,打算做某事”,此外,be going to 可表示根据现在的迹象对未来进行判断。
Look at those clouds. It’s going to rain. 看那些乌云,要下雨了。

1. 表示过去发生或已经完成的某一动作对现在造成的影响或结果。
I have just finished my homework. 我刚刚完成我的家庭作业。
表示从过去某时刻开始,持续到现在的动作或情况,并且有可能会继续持续下去,此时经常用延续性动词。时间状语常用since加一个过去的时间点,或for加一段时间,或加一个现在时间。
I have known him for three years. 我认识他三年了。
He has lived here since 1995.他自1995年以来就住在这儿。
【注意】(1)一般过去时与现在完成时的区别:过去完成时表示过去某时发生的动作或单纯叙述过去的事情,强调动作;现在完成时为过去发生的,强调过去的事情对现在的影响,强调的是影响;一般过去时常与具体的表过去的时间状语连用。
I saw this film yesterday. 我昨天看了这部电影。(强调看的动作发生过了,不涉及现在)
I have seen this film. 我看过这部电影。(强调对现在的影响,电影的内容已经知道了)

(3)句型It is/has been...since..所使用的两种时态都正确。

现在完成时的被动语态:主语+ have /has been + done

(五)现在进行时
1. 现在进行时表示说话时或现阶段正在进行的动作。

有时,现在进行时也与always等副词连用,表示反复出现的习惯性动作,用以表达说话人赞扬、讨厌等情绪。

表示状态的动词 be, have等; 表示认识,知觉和情感的动词know, think, hear, find, see, like, want, wish, prefer等一般不用于进行时。

(六)过去进行时
1. 表示在过去某一时刻或过去一段时间内正在发生的动作。

如果when, while这样的时间状语引导词所引导的主从句之一是一般过去时,则另一个句子常用过去进行时。
