Teaching procedures

Step One: 语气简述

1. 谓语动词的语气是用来表示说话人对所讲内容的态度、看法以及心情等

2. 英文句子中谓语动词的语气有三种:

  He has published quite a number of essays this year .

Wait outside until you are asked.

I wish you were more careful .但愿你更细心一些。

Step Two:

1.      区分真实条件句与非真实条件句。

2.      If 引导的虚拟条件句三种情况。

3.      If 引导的虚拟语气的倒装。

4.      其他一些基本用法


Step Three

1. 真实条件句与非真实条件句:

(4) If you drink too much whiskey, you will get sick. (            )

(5) If I were you, I would ask my parents for help. (            )

Look at a sentence:

?        You will get sunburned if you stay in the sun too long!



2. If 引导的虚拟条件句三种情况:

If I were you, I would put her suggestion into account.(事实是:我并不是你)我要是你,我会考虑她的建议的。

If I ______________I _________________________.

2. 要不是她这么忙,她就会出席今天下午的会议了。

If she _____________ so busy, she __________________the meeting this afternoon.



1. 主句中would可以用其他情态动词来换。(would intention; plan;   could ability; possibility;  might probability)

2. be动词在表示与现在事实相反的从句中一般用were。在非正式情况下,第一、第三人称后偶尔也用was

如:If he were/ was youhe would go at once.


If he had taken my advice, he might not have made such a bad mistake.

句型:  If had been/done,  would/could/might have done

If he_______________(hurry), he _____________________ the train.(catch)

2) 如果你昨天告诉他,他也许会提些建议了。

If you __________________, he _________________________. (make suggestions)



1. 与过去事实相反的if从句中,还可以用could have done来代替had done,主句不变。

e.g.: If I could have told you about cultural differences between Italy and the UK, I would have.

If I should have a chance to try it, I would do it in another way.
Even if they were to fail, they wouldn't lose courage.
