2、条件句1、If+主语+动词过去式2、If+主语+were to+ 动词原形3、If+主语+should +动词原形If I were to go abroad, I would go to America.主语+would(could should might)+动词原型错综时间条件句主从句时间不一致的情况下的虚拟语气有时条件从句中的动作与主句中的动作,发生的时间不一致,这是动作的形式应根据它所表示的时间加以调整。If you had followed my advice, you would be better now.If you had studied hard before, you
3、would be a college student now.含蓄条件句有时虚拟条件句并没用if从句表示出来,而是用介词短语(otherwise,or,without,but for)上下文或其他方式来表示。She would have died without my help.。条件从句中省略if采用倒装语序的情况在if引导的表示虚拟的条件状语从句中,有时可以把虚拟条件中的连词if省去,而将had,should,were等助动词提到主语之前。例:原句:1: If she were younger, she,would do it.去if:Were she younger, she would
4、 do it.2: If you had come earlier, you would have met him.去if: Had you come earlier, you would have met him3:If it should rain tomorrow, we would not go climbing.去if:Should it rain tomorrow, we would not go climbing.虚拟语气在as if/as though引导的方式状语从句中1. 表示与现在事实相反或对现在情况有怀疑,谓语动词用过去式。He treats the boy as if

6、语。虚拟语气用在lest,for fear that,so that及in order that引导的目的状语从句中表示“以防,以免”等意思谓语动词多用should/could/might+动词原型构成For fear that it may rain tomorrow, we should bring an umbrella.“In case”引导的从句中即可用陈述句,也可以用虚拟语气(should)+动词原型例:1.The game will be put off in case it (should) snow.2.The game will be put off in case it
7、snows.(二)名词性从句中的虚拟语气一:宾语从句中的虚拟语气1.在动词wish/hope后的宾语从句中的虚拟语气,表示一种不可能实现的愿望。对现在情况的虚拟:从句谓语动词用过去式或过去进行式。I wish (that) I were a bird.对过去情况的虚拟:从句谓语动词用过去完成时,或would,could,might+现在完成时。I wish (that) I had seen the film last night.对将来情况的虚拟:从句谓语“would/should/could/might+动词原形”。I wish (that) I wouldcould go.在表示建议,命

9、de, order注意:suggest, insist不表示建议或坚持要某人做某事时,即它们用于其本意暗示,表明,坚持认为时,宾语从句用陈述语气。The smile on his face suggested (暗示)that he was satisfied with our work.The man insisted 【坚持认为】that he had never stolen the money.Would rather,had rather,后的宾语从句中的虚拟语气谓语动词用过去式表示与现在或将来相反I would rather you told me the truth.用过去完成式
