We pushed the bus, but it wouldn't move a bit.

8.used to "过去曾经......"，暗示现在不再如此：

You used to smoke, usedn't you (didn't you)?

虚拟语气

近几年，虚拟语气考查的重点是与情态动词连用的虚拟语气。如：should have done, could have done, might have done等。虚拟条件句等也时有涉及。

1.虚拟语气在非真实条件句中的运用：

(1)与现在事实相反：

条件句谓语用：If...did/were...；主句谓语用：would (should,

could, might) do...。例如：

If I had enough money, I would buy the car. (But I haven't

enough money.)

If it were not so late, we could have coffee.

(2)与过去事实相反：

条件句谓语用：If...had done...;主句谓语用：would (should)

have done...。例如：

If they had invited me, I would have gone to the party. (But

they didn't invite me.)

They didn't invite me, otherwise, I would have gone to the party.

(3)与将来事实相反：

条件句谓语用：If...did (were)/were to do/should do...;主句谓语

用：would (should) do...。例如：

I'm sure to succeed this time. If I failed (were to fail/should fail),

I would try again.

(4)过去现在混合：

条件句与过去事实相反，主句与现在事实相反。例如：

If you had taken the doctor's advice, you wouldn't be in hospital

now (you would be well now).

(5)如果if省略，从句要倒装(主要是were/should/had)例如：

Had they time, they would help us.

Had you come earlier, you would have met the scientist.

(6)用介词短语代替条件句：

We would not have succeeded without your help (but for

your help).

But for the storm, we should have arrived earlier.

2.宾语从句中的虚拟语气：

(1)wish"希望；但愿"。wish后的宾语从句，如果跟虚拟语气，

有三种时态。即:
