高二 选修 6 Unit 1Unit 1 Art虚拟语气Subjunctive Mood (I)虚拟语气
在英语中，表示说话人所说的话不是事实，而是一种假设、愿望、怀疑或推测，要用虚拟语气。虚拟语气可以用于条件状语从句、主语从句、表语从句、宾语从句等。本节课我们主要学习if条件从句和wish后的宾语从句中表示现在或将来情况的虚拟语气的用法。【观察体会】
请看下图及对话，体会表示现在的虚拟语气的用法。A: Why don’t our grandchildren visit us
more often?
B: They don’t have enough time. If they
had more time, they’d visit us more
often.A: I wonder why Fred works so hard.
B: I don’t know. He must like his job.
A: If he didn’t like his job, he wouldn’t
work so hard.A: Do you enjoy driving a school bus?
B: Not really. I wish I drove a taxi.A: Can Jonathan dance?
B: No, he can’t, but he wishes he could.
If he could dance, he’d go dancing
every night.一、虚拟语气用于条件状语从句中
(1) 表示与现在事实相反的假设, 条件 状语从句中的谓语动词用“过去式(be 动词的过去式用were)”, 而主句中的谓语动词“would / should/ could / might + 动词原形”。 虚拟语气e.g. If I were a boy, I would join the
army.What would you do if you won the lottery?
If I won the lottery, I would…If I had a lot of money, I would buy a villa.If I had a lot of money now, I would travel around the world.If I had a lot of money, I would go shopping.a. If they _____ (be) here, they __________ (take) your advice.

2. Suppose you won a lot of money. What
would you do with the money? If I _____ a teacher, I would …were(2) 与过去的事实相反从句的谓语用had ＋ 过去分词, 构成 If I (we, you, he, they)＋had＋过去分词的形式；
主句的谓语用should(第一人称)/would (第二、三人称) / could / might have ＋动词过去分词。If he __________ more carefully, he _________________ the car accident yesterday.had driven would not have had If I __________ how to swim,I __________________ trapped in this island.had learnt would not have been a. If Tom ________ (be) more careful in the exam, he ________________ (pass) it already.

If you should succeed, everything would
be all right.
If you were to succeed, everything would be all right.If he got up early, he would be on time.假如他来了, 我们对他说什么呢？If he were to come, what should we say to him.假如他看见我, 就会认识我。If he should see me, he would know me.a.

e.g. If you had asked him yesterday, you
would know what to do now.
例句中从句与过去事实相反, 主句与现在事实相反。If the staff had been more careful, the mall would not be on fire now.过去时(were)would/could/should/might +v. (原)总结：虚拟语气在条件状语从句中的用

2. should + v.
3. were to dowould/could/ should/ might + v. (原)二、虚拟语气在宾语从句中的用法1. 在动词wish后的宾语从句中, 表示与现在或过去的事实相反, 或对将来的主观愿望, 从句通常省略连词that。1) 表示对现在情况的虚拟: 从句动词用过去式或过去进行式 (be动词一般用were) 。I wish I were as tall as you.I wish every day were my birthday.I wish/wished I hadn’t eaten so much watermelon.(2) 表示对过去情况的虚拟: 从句动词常用“had＋过去分词”。The party was terrible, I wish I had never gone to it.(3) 表示对将来的主观愿望: 从句动词形式为 “ would＋动词原形”。注意: 主句的主语与从句的主语不能相同, 因为主句的主语所期望的从句动作能否实现，取决于从句主语的态度或意愿(非动物名词除外)。
e.g. 但愿你立刻来。
I wish you would come soon.I wish it would rain tomorrow.2. 表示要求，命令，建议的虚拟语气。 常见动词： 一个坚持，两个命令，三个建议，四个要求。即:
