真实语气与虚拟语气的区别主要在谓语动词的形式上在做题时，要根据语境，判断出是与那种时态相反的虚拟语气一 虚拟语气在从句中的用法和构成一览表类别用法例句if引导的条件从句与现在事实相反从句动词：过去式（be用were）；主句动词：should/would/could/might +动词原形If he were here, he would help us.与过去事实相反从句动词：had +过去分词；主句动词：should/would/could/might +have +过去分词If I had been free, I would have visited you.与将来事实相反从句动词：过去式/should +动词原形/were +不定式；主句动词:should/would/could/might +动词原形If it should rain tomorrow, we would not go camping.其他状语从句as if 引导的状语从句中动词用过去式或过去完成式They are talking as if they had been friends for years.even if/though 引导的从句, 与现在将来/事实相反:从句动词用过去式,主句动词用should/would +动词原形。
与过去事实相反:从句动词：had +过去分词；主句动词：should/would +have +过去分词Even if they were to fail, they wouldn’t lose courage.宾语从句demand, suggest, order, insist等表命令、建议、要求后的从句中动词（should）+动词原形He suggested that we not change our mind.wish后的从句中分别用过去式、过去完成式和could/would+动词原形表示与现在、过去和将来情况相反I wish I could be a pop singer.主语从句在It is necessary/important/strange that…, It is suggested/demanded/ordered/requested that…等从句中，谓语动词用（should）+动词原形It is strange that such a person should be our friends.表语从句和同位语从句作idea, advice, order, demand, request等表命令、建议、要求的词的表语从句和同位语从句，其谓语动词用（should）+动词原形My advice is that you (should) finish your homework first.The idea that you (should) go is right.其他句型中It is time that…句型中动词用过去式或should+动词原形It’s high time that we left.would rather所接的从句中动词用过去式或者过去完成式I would rather you stayed at home now.If only句型中动词常用过去式或者过去完成式，表示强烈的愿望If only our dream had come true!二 其他要注意的事项1. 虚拟语气中出现be的过去式，只能用were。
2. suggest表 “暗示、表明”和 insist表示 “坚持认为”,其后的宾语从句用陈述句语气 例如：You pale face suggests that you are ill. / He insisted that he was right.3. if虚拟语气条件句中如有had, should, were，可省略if, 将其提前引起倒装 例如：Were I you, I would remain. / Had you told me earlier, I wouldn’t have missed it.4. 可用with, but for代替虚拟语气条件句例如：But for your help. I would have failed the exam. Without air there would be no life.1. as if/though, even if/though也可以不用虚拟，表示真实的情况例如：It looks as if it is going to rain.II、实战演练用所给动词的适当形式填空1. ---If he ________________ (warn), he ________________ (not take) that food.---Luckily he was sent to the hospital immediately.2. When a pencil is partly in a glass of water, it looks as if it _________________ (break).3. I would rather they _________________ (not hear) of the news.4. I wish I _______________ (have) a room of my own when I was a child.5. To the surprise of the public, the identification of the cause of such a simple event ___________________ (take) more than a year.6.
