大学英语专题辅导专题一：重点语法部分1第一章 虚拟语气 虚拟语气是动词的一种特殊形式，用来表示一种假设、意愿、建议、请求等不可能成为事实的情况。1虚拟语气用于非真实条件句 非真实条件句，往往表示一种不真实的假设。一般地，非真实条件句由连接词If引导，但也可以省略，还有其它一些形式的非真实条件句。 211谓语动词的各种形式在If引导的非真实条件句中，谓语动词具有以下特殊形式：3与现在 从 句 did,were, V-ed事实相反 主 句 would(should,could,might)+v.与过去 从 句 had+V-ed/been 事实相反 主 句 would(should,could, might) + have+v-ed对未来的 从 句 were to/should+ v 虚拟推测 主 句 would(should,could,might)+v. 41.1.1.和现在事实相反的非真实条件句 这类非真实条件句表示和现在事实相反的情况。比如： -I would/should certainly go if I had the time. 如果我有时间，我一定会去的。-If I were your father, I would criticize you more severely. 如果我是你父亲，我会更严厉地批评你。 5-How nice it would be if you could stay a bit longer！ 如果你能久留些日子，那多好啊！ -If I knew his address ,I would be able to write to him . 如果我知道他的地址，我就能给他写信了。-If he were here ,he might be able to help. 如果他在这里，他或许会帮忙的。61.1.2.和过去事实相反的非真实条件句 这类非真实条件句表示过去未发生的事情，和过去事实相反。比如： 7-If I had left a little earlier ,I would have caught the train. 如果我早一点离开的话，我就会赶上火车了。-The mans life might have been saved if he had been sent to a better hospital.如果把那个人送到一家更好的医院的话，他也许回被救活的 8-I could have done better if I had been more careful. 我要是更细心一些的话，会做得更好的。 You wouldnt have caught cold if you had put on more clothes. 你如果多穿些衣服，就不会着凉了。91.1.3.对未来事情的虚拟推测 这类非真实条件句表示对未来事情的虚拟推测。-If I were to/should do it ,I would do it in a different way.10 这类非真实条件句表示对未来事情的虚拟推测。-If I were to/should do it ,I would do it in a different way. 如果我去做这事的话，我会用不同方式去做的。-If this were to happen again , we wouldnt let you off so easily. 如果这样的事情再次发生，我们不会如此轻易的放过你的。-If they should dare to invade our country , we would wipe them out completely. 如果他们胆敢侵略我们国家，我们会将他们全部消灭掉。 111.1.4.省略If的非真实条件句 虚拟条件句中的连接词if省略时，要把were, had, should移到从句的主语之前。比如:-Were I rich (=if I were rich), I would give you some money.如果我富有的话，我会给你一些钱的。12-Had I had more time (=If I had had more time), I would have finished my homework. 如果我有更多些时间，我一定已经完成家庭作业了。-Should he come early (=If he should come early), tell him to wait for his wife. 如果他来得早，告诉他等候他的妻子。 131.1.5.错综时间非真实条件句 主句表示的动作和从句表示的动作所发生的时间不一致时，动词的形式要根据表示的时间进行调整 ，如果从句表示过去，而主句表示现在，或者从句表示现在，而主句表示过去，可以使用混合虚拟形式. -If she had taken the doctors advice, she wouldnt be in hospital now. 如果她听从医生建议的话，现在也就 不会住院了。14如果汤姆通过了大学考试，他现在就在这所大学里学习了。-If she wasnt so busy now, she might have joined us in the work. 如果她现在不那么忙，她或许会参加我们的工作。 -Tom would be studying at the university now if he had passed the entrance examination. 151.1.6.含蓄条件句英语中有些句子从形式上看不包含条件从句，但在意义上却是非真实条件句，这类句子称为含蓄条件句，这样的句子可分为三类 161.省略整个条件句 -Such mistakes could have been avoided.
