2017年6月大学英语四级语法：虚拟语气

　　虚拟语气在考试中比较常见。尤其是在听力中经常出现。它主要是表达一种“假设”或者“推测”，而不是客观显示中的真实事件。因为主要通过动词的变化来反应不同的情况，所以如果不熟悉虚拟语气的基本表示方法，会直接影响听力。同时翻译中也经常使用。如果想得高分，要学好这个语法点，争取在翻译部分多拿点分：

　　基本规则：

     条件从句

主句

与现在事实相反

动词过去式

should/would+动词原形

与过去事实相反

had+过去分词

should/ would +have+过去分词

与将来事实可能相反

动词过去式/were to/should

should/ would +动词原形

　　与现在事实相反：

　　If I were you , I would apply for the job.

　　与过去事实相反：

　　If I had taken your advice, I wouldn’t have made such mistake.

　　与将来事实相反：

　　If it rained tomorrow, I would stay at home.

　　真题翻译示例：

　　例1：

　　They requested that _______(我借的书还回图书馆)by next Friday.

　　1. 动词request引导的从句应用虚拟语气

　　2. 虚拟语气的表达方式：should+动词原形，此题则为：should return

　　3. 按句意顺序译，得出答案：I should return the book to library

　　例2：

　　The victim ________(本来有机会活下来)if he had been taken to hospital in time.

　　1. 一看句意有“本来”，十之八九为虚拟语气

　　2. 二看时态推后了，本该过去时，却用过去完成时，因此一定考虚拟

　　3.按句意译为：would have a chance to survive

　　哪些动词及其与他们相关的名词，从句需虚拟语气?

　　一想要(desire)二宁愿(prefer)三命令(order. command)

　　四建议(advice. suggest. propose)

　　五要求(demand. require. request. ask. insist)，另加一个wish

　　答案及解析：

　　1. C 2. C 3. D 4. C 5. D 6. B 7.B 8. B 9.D 10. D

　　1. It is strange that是主语从句的虚拟语气，从句用sb. should do的形式。

　　2. suggest后面的从句用sb. should do的形式，should可以省略。

　　3. 虚拟语气。wish从句后接虚拟语气。could have done表示“本来可以”。

　　4. in advance表示“事先”， would have done表示与过去事实相反的虚拟语气。

　　5. wish的宾语从句表示发生在将来的愿望用过去将来时。

　　6. wish后面用虚拟语气，表示与过去事实相反用过去完成时。

　　7. 条件句表示与过去事实相反，主句用过去将来完成时，从句用过去完成时。

　　8. would have done是过去将来完成时，表示与过去相反的虚拟语气。

　　9. 在虚拟语气中，不管什么人称，be动词都要用were的形式。

　　10. had I known是与过去相反的虚拟语气的倒装形式，因此主句要用would have done。
