1.（2010高考英语天津卷）John went to the hospital alone. If he me about it, I would have gone with him. A. should tell B. tells C. told D. had told
【答案】D 【解析】主从句都是对过去发生事实的一种意愿表达， 从句采用have done的结构，故选D。
【答案】 D 【解析】表示与过去事实相反的假设，故主句用 would/could/might/should+have done，即D项 正确。
注意以下问题：
1. 错综时间虚拟条件句 2. (if省略) 倒装虚拟条件句 3. 含蓄条件句
3、错综时间虚拟句（混合虚拟条件句)
通常情况下,在非真实条件句中主句和从句的 谓语动词所指时间是一致的,但有时也可能指 不同的时间,这时要根据上下文的意思采用不 同的谓语动词形式。虚拟条件句和主句动作如 发生的时间不一致，主句和从句的谓语要根据 各自所指的不同时间选用适当的虚拟语气形式， 这种句子叫做错综时间条件句。

虚拟语气公开课
虚拟语气公开课在英语学习的广袤领域中，虚拟语气无疑是一座令人望而生畏的山峰。
但别怕，今天这堂公开课，咱们就一起来勇攀这座高峰，把虚拟语气给拿下！咱们先来聊聊啥是虚拟语气。
简单说，虚拟语气就是用来表达一种假设、愿望、建议或者与事实相反的情况。
比如说，“要是我会飞就好了”，这就是一种愿望，用英语表达可能就是“If I could fly, it would be great” 这里的“could fly”就是虚拟语气。
为啥要学虚拟语气呢？这可太重要啦！它能让咱们的英语表达更丰富、更准确，也更能传达出细腻的情感和想法。
想象一下，你跟朋友聊天，想说“我真希望当时听了你的建议”，要是不会虚拟语气，那可就表达不出那种后悔和遗憾的心情了。
那虚拟语气都有哪些类型呢？常见的有三种：与现在事实相反的虚拟语气、与过去事实相反的虚拟语气以及与将来事实相反的虚拟语气。
先来说说与现在事实相反的虚拟语气。
假设现在的情况不是这样的，咱们的句子结构一般是“if ＋主语＋动词过去式，主语＋would/could/might ＋动词原形”。
举个例子，“如果我有很多钱，我会买一辆豪车”，英语就是“If I had a lot of money, I would buy a luxury car” 这里的“had”就是“have”的过去式，“would buy”体现了虚拟的情况。
再看看与过去事实相反的虚拟语气。
这种情况是假设过去发生的事情不是那样的，结构通常是“if ＋主语＋ had ＋过去分词，主语＋would/could/might ＋ have ＋过去分词”。
比如说，“要是我当时努力学习了，我就能通过考试了”，英语就是“If I had studied hard, I would have passed the exam” 注意这里“had studied”和“would have passed”的用法。
最后是与将来事实相反的虚拟语气。

虚拟语气
虚拟语气的概念
• 虚拟语气是一种特殊的动词形式，一是用 来表示说话人所说的话不是一个事实，而 是一种假设、猜测、怀疑等(在条件从句中 或让步状语从句中)；一是表示说话人的愿 望、要求、命令、建议等 (在宾语从句、表 语从句、同位语从句)。
一. If虚拟条件句 二. 1. 三种情况（现在，过去，将来） 三. 2. 省略if的条件从句 四. 3. 错综时间条件句 五. 二. 动词wish后的宾语从句 六. 三. should have done表示的虚拟
she probably wouldn't be able to see her
friends very often.
A. has to get
B. had got
C. were to get NhomakorabeaD. could have got
虚拟语气
2、省略 if 的条件从句
当从句中有 were, had 或 should 时，可省略if ，而 把它们放在句首。
虚拟语气
一、虚拟语气在 在条件从句中
1、在条件从句中 (叫虚拟条件句)，表示与事实相反 的条件。分三种情况(以 do 为例)：
从句
主句

B. weren't
B. C. wasn't
D. hadn't
been 4. Mary doesn't want to work right away
because she thinks that if she _____ a job
虚拟语气
虚拟语气在复合句中的应用：
3、错综时间的条件句
即从句与主句的动作发生的时间不同。此时，需要 按时间来确定虚拟形式。如：
• If they had studied hard, they could do it easily now. 如果他们(以前)努力学习的话，现在干的就会容 易些。
• If he had not taken my advice, he wouldn't do it much better like this. 如果他不听取我的建议，他就不会干得这样好。
• If it should rain tomorrow, the sports meeting would be put off.
= Should it rain tomorrow, the sports meeting would be put off.
• If you had come a little earlier, you would have seen her.
与将来事实相 反
①过去式 (did) 主语+would / could / If+主语+②should + do might / should + 动词
③were to do 原形（do）
