1. (2008山东)Thank you for all your hard work last week. I don’t think we ______ it without you。

A. can manage B. could have managed C. could manage D. can have managed

考点解析：句中的介词短语without you表示一个假设的条件，而时间状语last week表明句子陈述的内容与过去的事实相反，因此最佳答案为B。

7. had thought/hoped/meant/intended/expected/wanted/planned that + 从句 表示主语过去未曾实现的愿望。

We were to have arrived at 9:00 this morning, but I missed the first bus.

I had hoped that I would be of some help to you, but you didn’t ask me。

-Lucy is crying in the corner now. Did you scold her for her carelessness in her homework?

-Yes, but I’d rather not have done it. 我要是不批评她就好了。

6. 在“had better/would rather, would like/love to, was/were to+ have done sth ”表示过去希望做某事，但事实上未做。例如：

- Do you mind if I open the window?

-I’d rather you didn’t. I feel a bit cold。

5. 如果as if/though从句描述的是真实的情况，谓语动词则用陈述语气，而不用虚拟语气。

It looks as if it is going to rain。

It sounds as though she has been really ill。

4. 若insist表示“坚持说”，suggest表示“暗示，表明”，其后的宾语从句用陈述语气。

The smile on the boy’s face suggested that he was happy to die for his country。

The man insisted that he had not stolen anything and (should) be set free immediately。

3. 在一些日常会话中，一些简单句通常暗含虚拟的意味。句中的谓语动词用would/could/ should be等形式或should/would/could/might have been等形式。

It couldn’t be better. 那太好了。

That would be very nice. 太好了。

I couldn’t agree with you more. 我非常同意你的意见。

I wouldn’t have dreamed of it. 我做梦也没有想到啊!

2. 有时，只在条件句或主句中使用虚拟语气，而另一分句用陈述语气。

If you should change your mind, do let me know。

Should anyone call (= If anyone calls)， please tell them that I’m busy。

Can you read that form carefully, if you wouldn’t mind, and then sign it?

I would appreciate it if you call back this afternoon for the doctor's appointment.

-What would you do if it rains tomorrow?

-We have to carry it on, since we’ve got everything ready。

1. 错综时间虚拟条件句中

如果if条件句表示的动作与主句表示的动作发生的时间不一致，从句和主句的谓语动词的形式要根据各自的时间来调整， 这种情况被称作“错综时间虚拟语气”或“混合虚拟语气”。

If America had not made wars on Iraq, the Iraqi people would be living a peaceful life now。

If I were you, I would have visited the museum yesterday.

If we didn’t have an exam tomorrow, my friends and I could be playing football now。

7. 在简单句中

⑴情态动词Would/could/might，表示说话人的礼貌或委婉的语气，常用于日常会话中。

Could you let me have your passport? 看看你的护照好吗?

Might I speak to you for a moment? 我能和你谈一下吗?(使用might比may更客气)

⑵表示祝愿

“may+动词原形”表示祝愿，通常把may置于句首，构成倒装语序。

May you succeed in the future!

May the friendship between us last long!
