雅思高分语法

——完成时态

  雅思总分要上7,语法关一定要过。今天我们就给大家介绍一个口语写作加分的高分语法,完成时态和虚拟语气。熟练掌握,上7不愁。

Perfective Aspect 有关完成时态

  现在完成时:

  现在完成时表示从过去持续到现在

  They’ve beenmarried for nearly fifty years.

  他们结婚已经快50年了。

  She has lived in Liverpool all her life.

  她一生都住在利物浦。

  … or is important in the present:

  或者表示目前还很重要

  I’ve lostmy keys. I can’t get into the house.

  我丢了钥匙,进不了屋了。

  Teresa isn’t at home. I think she has goneshopping.

  Teresa不在家,我认为她去购物去了。

  

  现在完成进行时:

  We use the present perfect continuous to show that something has been continuing up to the present:

  现在完成进行时描述的是某事一直不停持续到目前。

  It’s been rainingfor hours.

  过去几小时雨没停。

  We’ve been waitinghere since six o’clock this morning.

  我们从早上六点就一直在这等。

  

  过去完成时:

  We use the past perfectto show that something continued up to a time in the past:

  过去完成时描述的是持续到过去的一个时刻。

  When George died he and Anne had beenmarried for nearly fifty years.

  当George去世的时候,和他安妮已经结婚快50年了。

  ... or was important at that time in the past:

  或者表示在过去那个时候很重要

  I couldn’t get into the house. I had lostmy keys.

  我当时进不去门,是因为我找不到钥匙。

  Teresa wasn’t at home. She had goneshopping.

  过去完成进行时:

  过去完成进行时描述的是某事不停持续到过去某个时刻

  当时很湿,在此之前雨下了好几个小时。

  He was a wonderful guitarist. He had been playingever since he was a teenager.

  将来完成时:

  We use will with the perfect to show that something will be complete at some time in the future:

  用will和完成时态组合描述某事在将来某个时刻结束。

  再过几年,他们就会找到治疗普通感冒的药物。

  我今晚可以出来,预计那时候我会完成作业。

  虚拟语气:

  We use would with the perfect to refer to something that did not happen in the past but would have happened if the conditions had been right:

  用would加完成时,描述某事事实上没有发生,但是如果情况允许的话,是会发生的。

  If you had asked me I would have helpedyou.

  如果你当时找我的话,我会帮你的。

  I would have helpedyou, but you didn’t ask me.

  你不来找我,要不然我会帮你的。

  用其他情态动词加完成时,用来描述从某个时间点回顾过去(或者展望未来),某事有可能发生,应该发生,或者理应发生。

  We use other modals with perfective aspect when we are looking backfrom a point in time when something might have happened, should have happened or would have happened.

  时间点也有可能是将来某个时刻:

  The point of time may be in the future:

  We’ll meet again next week. We might have finished the work by then.

  我们下周还会再见,到时我们可能已经完成工作了。

  I will phone at six o’clock. He should have got home by then.

  六点我打给你。到时他应该到家了。

  时间点是现在:

  the present:

  It’s getting late. They should have arrived by now.

  越来越晚了。他们应该到了呀。

  He’s still not here. He must have missed his train.

  他还没来,肯定是错过班车了。

  时间点是过去:

  or the past:
