编者按：有些时候，不用条件句，而用一个词组、暗含的意思表示假设，这样的句子就是含蓄条件句。下面小编就来带你一起学习下纯假设虚拟句中的含蓄条件句，希望对大家有帮助。
英语中用得最多的是陈述语气，其次是疑问、祈使语气，只有很少一些场合用虚拟语气。
含蓄条件句
有些时候，不用条件句，而用一个词组、暗含的意思表示假设，这样的句子就是含蓄条件句。
用with, without等介词引导的介词词组，或者分词词组，独立主格结构代替条件句。
You wouldn’t have succeeded without their support.
=You wouldn’t have succeeded if they hadn’t supported you.
如果没有他们的支持，你们就不会成功了。
What would you do with 100,000 dollars?
如果你有10万美元，你会怎么花?
Having foreseen the storm, she wouldn’t have gone out.
要是预见到暴风雨要来，她就不会出去了。
除if外，还有一些连词能引导虚拟句。这些连词主要有：
in case万一
lest生怕
as if好像
unless除非
as through好像
on condition that条件是
otherwise否则
suppose(that)假设
but that要不是
provided/providing(that)如果
Take an umbrella with you in case it should rain.
带把伞去，万一会下雨。
The kid spoke as if he were a group-up.
那孩子说话真像个大人一样.
模仿造句:
1.现在就出发,万一路上堵车。
2.那个女孩说话真像个大人一样。
通过上下文的意思表示的虚拟句
She would have helped you, but she was too busy at the time.
她本来想帮你的，但她当时太忙。
I should have discussed with you, but I could not find you anywhere.
我本来应该同你商量的，但我到处找不着你。
有时单独用虚拟条件句可作感叹句或者疑问句
If only I could fly!
要是我能飞多好啊!
If only I were as tall as you!
要是我同你一样高多好啊!
What if she were dishonest?
如果她不诚实会怎么样?
模仿造句:
要是我现在就参军多好啊!
如果我是一个电影明星多好啊!
如果他不友好会怎么样!
虚拟条件句的省略和倒装
在书面语中(口语中极少)有时将虚拟条件句的if省去,将主语后的助动词(或者情态动词)移到主语前。
If we had finished earlier, we could have won the first place.
→Had we finished earlier, we could have won the first place.
如果我们早一点完成，我们就能获得第一名了。
If I should have the chance, I would try it.
→Should I have the chance, I would try it.
如果我有机会，我会试一下的。
If I were at college now, I would work very hard.
→Were I at college now, I would work very hard.
如果我现在在上大学，我会非常下功夫的。
