虚拟语气在非真实条件句中的运用

学科

英语

虚拟语气属于英语语法中比较难理解的重要知识点，很多学生的逻辑思维能力和语境分析能力不强，所以很难掌握虚拟语气在语言表学情分析

达中的运用。特别是在语法填空题和阅读理解中很难一眼识别出虚拟语气。

本节课通过系统地总结虚拟语气在高考中的考点，结合历年高考真教学目标

题帮助学生在考试中快速地识别虚拟语气并能正确地运用虚拟语气的不同时态。

教学方法

本节课采用分组讨论，老师讲解归纳，学生演练，老师答疑等方法

step 1: 模拟情境让学生讨论：

T:“what would you take if you were sent to the space ?”

S:I would …

step 2: 由情景对话引出虚拟语气在非真实条件句的运用：

（1）：错综时间条件句 （2）：if省略句

（3）：含蓄条件句 （4）：半虚拟

Step 3: 让学生阅读教材例句总结

If 条件句虚拟语气主从句谓语的时态：

If从句

主句

对现在的虚拟

did/were would/should/could/ might do 教学过程

对过去的虚拟

had done would/should/could/ might have done

did

对将来的虚拟

should do would/should/could/ were to do might do

做题口诀

：

主过将/从过

主过将完/从过完

主句时态若为过去将来时（would do）从句用一般过去时（did/were）

主句时态若为过去将来完成时（would have done）,从句时态用过去完成时（had done）

注意：此口诀不适用于错综时间条件句

Step 4:高考真题演练：

例1：（陕西卷）If we B the other road, we might have arrived here in time for the meeting. A.take B.had taken C.took D. have taken

例2：（2013重庆卷）

--It rained cats and dogs this morning. I’m glad we took an umbrella. --Yeah, we would have got wet all over if we A . A. hadn’t B. havn’t C. didn’t D. don’t

Step 5:错综时间条件句：让学生观察例句并填上正确的时态

例3：If you had followed (follow) my advice just now, you would be (be) better now.

例4：If you (study) hard before, you (be) a college student now. 做题技巧：找出主从句分别表示什么时间（过去、现在、将来）动词的形式根据它所表示的时间作出相应的调整。

例5：Maybe if I C science, and not literature then, I would be able to give you more help. A.

Studied B. would study C. had studied D. was studying 例6：If we D a table earlier, we couldn’t be standing here in a queue. A.

have booked B. booked C. book D. had booked

Step 6: If 省略句

让学生观察例句并选出正确答案

例7： A today, he would get there by Friday. A.

Were he to leave B. If he had left C. Did he to leave D. Had he left

Step 7: 让学生观察下列从句是如何变成省略句的？

（1） If I were you, I would not let her go. = Were I you, I would not let her go. (2) If they had helped us, we would not have failed it. = Had they helped us, we would not have failed it.

步骤：去掉if ,从句变一般疑问语序（倒装）

Step 8:高考真题演练

例8：（2014天津）

D the morning train, he would not have been late for the meeting. A. Did he catch B. Should be catch C. has he caught D. Had he caught

例9：

D the clouds, you would find the airplane in the sky easily. A.

Had it not been for B. If it were not C. If it had not been for D. Were it not for

Step 9:含蓄条件句

句中含有with, without, but for, or, otherwise, or else等，

虽然没有出现if, 但表示的是if 的含义。

例如：

(1): Without your help, I wouldn’t have passed the exam. =If you didn’t help me, I wouldn’t have passed the exam. = But for your help, I wouldn’t have passed the exam.

(2): I don’t have your telephone number , otherwise/ or I would have called you back. =If I had your number, I would have called you back.

(3): What would you do with a million dollars? =What would you do if you had a million dollars? 注意：从句中出现but for, or, otherwise, or else 一般都是对过去的虚拟，所以从句通常使用过去将来完成时（would have done）

Step 10:真题演练：

例10：（2012福建）We lost our way in that small village, otherwise we D more places of interest yesterday. A. visited B. had visited C. would visit D. would have visited

例11：But for the help of my English teacher, I B the first prize in the English Writing Competition. A. would not win B. would not have won C. would win D. would have won

Step 11:半虚拟

让学生观察例句找出主从句中是否使用虚拟语气

I might have given you more help, but I was too busy. 半真半假，but 是标志词

（but 后面的句子是真实情况该用什么时态就用什么时态，不用虚拟）

真题演练：（安徽卷）

Bob would have helped us yesterday, but he A . A. was busy B. is busy C. had been busy D. will be busy

I did not attend the lecture by Pro. Jackson. I C but I all this morning. A.

would, have washed B.

could, have been washing C.

would have, have been washing D.

could have, had washing Step 12: Homework

对于语境感悟能力差的理工科学生来说，很难把握虚拟语气在非真实条件句中的应用。

教学设计本课把虚拟语气总结归纳成条理公式类的知识让学生能在阅读思路

理解或语法填空中一眼识别出虚拟语气并能选择正确的时态。

结合了高考真题的演练让学生熟记虚拟语气做题的几个要领和口诀。
