純假設(shè)虛擬句中的含蓄條件句知識講解
編者按：有些時候，不用條件句，而用一個詞組、暗含的意思表示假設(shè)，這樣的句子就是含蓄條件句。下面小編就來帶你一起學(xué)習(xí)下純假設(shè)虛擬句中的含蓄條件句，希望對大家有幫助。
英語中用得最多的是陳述語氣，其次是疑問、祈使語氣，只有很少一些場合用虛擬語氣。
含蓄條件句
有些時候，不用條件句，而用一個詞組、暗含的意思表示假設(shè)，這樣的句子就是含蓄條件句。
用with, without等介詞引導(dǎo)的介詞詞組，或者分詞詞組，獨立主格結(jié)構(gòu)代替條件句。
You wouldn’t have succeeded without their support.
=You wouldn’t have succeeded if they hadn’t supported you.
如果沒有他們的支持，你們就不會成功了。
What would you do with 100,000 dollars?
如果你有10萬美元，你會怎么花?
Having foreseen the storm, she wouldn’t have gone out.
要是預(yù)見到暴風(fēng)雨要來，她就不會出去了。
除if外，還有一些連詞能引導(dǎo)虛擬句。這些連詞主要有：
in case萬一
lest生怕
as if好像
unless除非
as through好像
on condition that條件是
otherwise否則
suppose(that)假設(shè)
but that要不是
provided/providing(that)如果
Take an umbrella with you in case it should rain.
帶把傘去，萬一會下雨。
The kid spoke as if he were a group-up.
那孩子說話真像個大人一樣.
模仿造句:
1.現(xiàn)在就出發(fā),萬一路上堵車。
2.那個女孩說話真像個大人一樣。
通過上下文的意思表示的虛擬句
She would have helped you, but she was too busy at the time.
她本來想幫你的，但她當(dāng)時太忙。
I should have discussed with you, but I could not find you anywhere.
我本來應(yīng)該同你商量的，但我到處找不著你。
有時單獨用虛擬條件句可作感嘆句或者疑問句
If only I could fly!
要是我能飛多好啊!
If only I were as tall as you!
要是我同你一樣高多好啊!
What if she were dishonest?
如果她不誠實會怎么樣?
模仿造句:
要是我現(xiàn)在就參軍多好啊!
如果我是一個電影明星多好啊!
如果他不友好會怎么樣!
虛擬條件句的省略和倒裝
在書面語中(口語中極少)有時將虛擬條件句的if省去,將主語后的助動詞(或者情態(tài)動詞)移到主語前。
If we had finished earlier, we could have won the first place.
→Had we finished earlier, we could have won the first place.
如果我們早一點完成，我們就能獲得第一名了。
If I should have the chance, I would try it.
→Should I have the chance, I would try it.
如果我有機(jī)會，我會試一下的。
If I were at college now, I would work very hard.
→Were I at college now, I would work very hard.
如果我現(xiàn)在在上大學(xué)，我會非常下功夫的。
