  1.虚拟语气可以表示过去,现在和将来的情况,时态的基本特点是时态往后推移。
  2.虚拟语气表
  二、混合条件句(错综时间条件句)
  有时,主句与从句的动作发生在不同的时间,主句和从句谓语动词的虚拟语气形式因时间不同而不同,这种条件句叫作混合条件句。
  三、含蓄条件句:是指非真实条件句中的条件从句有时不表示出来,只暗含在上下文中。含蓄条件句常见的表达方式有:
  1.定语从句和状语从句
  Anyone who had married such a girl as she would have been regretful. 谁娶了像她这样的姑娘都会后悔的。
  Help was promised where it should become necessary.
  要是需要的话就答应给予帮助。
  2.介词及介词短语:but that, but for, without, with, under, under …condition, supposing, suppose, on condition that, in the past等。
  Without your help, I couldnt have achieved all this.
  要不是有你帮助,我不会取得这些成就。
  But for the fog we would have reached our destination long ago. 要是没有雾的话,我们很早就到目的地了。
  Under more favourable conditions we could have finished the task.
  如果条件对我们更有利,我们就会把工作完成得更好了。
  3.连词otherwise, or, but
  He would have given you more help, but he has been so busy.
  他本来可以多给你一些帮助的,只是他太忙了。
  Seize the chance, otherwise you would regret it.
  如果不抓住这个机会,你会后悔的。
  He felt very tired yesterday, or he would have helped you.
  他昨天觉得太累了,不然他会帮你的。
  4.通过分词短语表示条件
  Given more time, we could have done it better.
  如果多给一点时间,我们会做得更好的。
  Legalizing this drug would have disastrous consequence.
  使毒品合法化会有灾难性的后果。
  5.用动词不定式表示条件
  It would be a mistake not to help him.
  没有帮助他是个错误。
  四、虚拟语气在宾语从句中的运用
  1.虚拟语气用在would rather,would(just)as soon,would sooner,would prefer(希望)等后接的宾语从句中。
  表示某人宁愿让另一个人做某事,其后的宾语从句的谓语动词需用虚拟语气。若表示现在或将来要做某事,从句谓语动词需用一般过去时;表示过去已经做的事,从句谓语动词用过去完成时。 1 2 3 4 5 下一页
