解题思路
本题前半句是表示与过去事实相反的虚拟条件 从句，后半句是表示与过去事实相反的主句。 相当于：If he had worked harder, he would have got through the exams.本题的 答案是B. would have got through。 选项A. must have got through（肯定通过） 表示一种对过去事情的主观推测，不是与过去 事情相反的情况。另外，must不能用在虚拟条 件句中。 选项C. 和D. would / could get through （就会通过）是虚拟语气现在时的一种表示方 法，表示与现在事实相反。
为什么要学习虚拟语气？
虚拟语气是四级考试中重点考察的语法 点。历年四级考试中，仅仅单项填空部
分就一共出现了48道虚拟语气的题 目！！！
II. 虚拟语气的最基本形式
非真实性条件句是虚拟语气最基本的表 现形式。
i. 由“if” 来引导的非真实条件句
组成方式： 非真实的条件从句 + 假设结果（主句）
最基本形式的表达方式
语法要点
虚拟语气 Subjunctive Mood
I.什么是语气？
语气是动词的一种形式，用以表示说话 人对某种言行或某种事情的看法或态度。 英语有三种语气：陈述语气，祈使语气 和虚拟语气。 陈述语气一般用来讲述事实或提出疑问。 常常用于陈述句、疑问句和感叹句。 e.g. I took a shower after supper. What are you going to do? What a beautiful flower!
A case in Point
P. 37 (l. 28) in College English II. Unit 3 Were it left to me to decide whether we should have a government without newspapers or newspapers without a government, I should not hesitate a moment to prefer the latter. = If it were left to me to decide…

背景知识:
语气:谓语动词的一种形式,表示说话人的态度和意图.
分类:陈述语气(现实,符合事实)
祈使语气(说话人的建议,请求,命令,邀请)
虚拟语气(动作或状态不是事实,或者是不可能发生的情况,
而是说话人的一种愿望,建议,命令,假设或推测)
e.g. I am a student, so I study hard. 陈述
注2:错综时间条件句
如果虚拟条件主句和从句的动作发生的时间不一致,主句和从句的
谓语动词要根据各自所指的不同时间选择适当的动词形式, 如:
If I were you, I would not have missed the film last
night.
(现在----过去)
If they had started in the early morning, they would arrive in half
“If I could… ,I would…. ” or
“If I were …,I would….”
二. 虚拟语气在名词性从句中的用法 (主，宾，表，同位）
1.宾语从句 a. wish+宾语从句，表示很难实现的愿望
现在 过去 将来
过去式（be动词用were)
过去完成时，或could/would +have done could/would +动词原形

B. should be worried.

3. If you had come yesterday, you would have met him.

实战练习 5
2001年1月大学英语四级题目： Some women a good salary in a job instead of staying home, but they decided not to work for the sake of the family. A. must make B. should have made C. would make D. could have made
解题思路
这是一道错综时间虚拟条件句。 在本句中，从句是对过去发生的事情进 行假设，主句是对现在情况的假设。 译文：当你掉下来时，如果不是我在梯 子下面把你接住，恐怕你现在就不会笑 了。选A
实战练习 2
If you had taken your medicine yesterday, you ___ well now. A. are B. had been C. would be D. were 正确答案: C
祈使语气主要用于祈使句。 e.g. Get out of here! 虚拟语气
II. 什么是虚拟语气？
虚拟语气是一种特殊的动词形式，表示说话人 所说的话不是事实，而是想象、假设、建议、 打算、意见、愿望、怀疑、推测、喜悦等等。 e.g. If we had met her last night, we would have told her what had happened. 如果我们昨晚见到她，我们就会告诉她发生了 什么事。 （实际上，我们并没有见到她，也没有告诉她 所发生的事。）
注意！！！
如果条件从句是否定式，倒装时只能把 not 放在主语之后，不能用缩写式把not 放在主语之前。 e.g. Had you not told me about the matter, I should never have known the whole thing. (不能说：Hadn’t you told me…)
