含蓄条件句

非真实条件句中的条件从句有时不表出来，只暗含在上下文中，这种句子叫做含蓄条件句。含蓄条件句大体有三种情况:

1. 条件暗含在短语中。如：

W hat would I have done without you?

(条件暗含在分词短语without you中)

It would be easier to do it this way.

(条件暗含在不定式短语to do it this way 中)

But for your help we couldn’t have succeeded in the experiment.

(暗含条件是but for your help)

This same thing, happening in wartime, would lead to a disaster.

(条件暗含在分词短语happening in wartime中)

He must have the strength of a hippopotamus, or he never could have vanquished that great beast.

(暗含条件是连词or)

Alone, he would have been terrified.

(暗含条件是alone)

2. 条件暗含在上下文中。如：

You might stay here forever.

(可能暗含if you wanted to)

 We would have succeeded.

(可能暗含if we had kept trying)

Your reputation would be ruined.

(可能暗含if you should accept it)

I would appreciate a little of your time.

(可能暗含if you were so kind as to give me a little of your time)

3. 在不少情况下，虚拟式已变成习惯说法，很难找出其暗含的条件。如： You wouldn’t know. 你不会知道。

I would like to come. 我愿意来。

I wouldn’t have dreamed of it.

这是我做梦也不会想到的。
