一、虚拟条件句

概念:一种表示愿望，建议，假设的语气，用来表示说的话不是事实，或者可能性很小的情况。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。句中的条件从句与结果主句皆须用虚拟语气。其主句和从句的动词形式具体如下表：

If you were in my position, what would you do? (与现在事实相反)

If I had been you then, I wouldn’t have quarreled with him. (与过去事实相反)

If I saw/ should see /were to see him tomorrow, I would be very happy. (与将来事实相反)

【跟踪演练】

1）.要是我上个学期努力学习英语的话，我就不会考试失败了。

2）.假如他今晚能回来的话，他也许会给你一些建议。

3）.要是我是你，我明天就向老师道歉。

4）.要是我是你，我就听老师的建议。

二、(省if )倒装条件句

如果条件句中有were, had（助动词）或should时，可使用倒装结构，但if必须省略。若条件从句为否定句，否定词not应置于主语之后，而不能与were，should，had等缩略成weren’t，shouldn’t，hadn’t置于句首。例如：

1. Had I seen him then, I would have been very happy.

= If I had seen him then, I would have been very happy.

2. Should I have time, I would go with you. = If I should have time, I would go with you.

3. Were I not so busy, I would go with you. = If I were not so busy, I would go with you. 【跟踪演练】

B. I were

C. Were I

D. Was I

2. _____ difficulties, we would be successful.

A. Should we overcome

B. Would we overcome

C. Might we overcome

D. Could we overcome 3. _____ the exam, he would have attended college. A. If he passed B. Had he passed C. Were he passed D. If he should pass 4. _____ five minutes earlier, you could have seen them off. A.If you should arrive B. If you arriveC. Had you arrived D. Should you arrive 三、错综时间条件句 有时，条件从句的动作和主句的动作发生的时间不一致。例如: 一个是过去发生的，一个是现在发生的。这时主从句中的动词形式要根据所表示的时间作相应的调整。例如: 1. If he had followed the doctor’s advice then, he would be quite all right now. 2. Tom would be alive today if the doctor had come sooner last night. 四、含蓄条件句 虚拟条件句中的条件从句有时不表现出来，只暗含在上下文中或用介词短语(without ，but for…) 或连词 (or, otherwise…) 等来表示，这种句子叫做含蓄条件句。例如： Bur for/ Without your help, we wouldn’t have succeeded. = If you had not helped us… I’m really very busy, otherwise, I would certainly go there with you. = If I were not v ery busy… 五、其他形式的虚拟句 1.wish

I would rather you came tomorrow. 【跟踪演练】 （1）我真希望你告诉我真相。 （2）我宁愿不再见到你。 （3）我倒希望他们和我一起去。

5. It’s (about/high) time +that 过去式\should +v . 我们该去睡觉了。
