托福写作:条件句的用法解析
先看两个例子:
[Scenery]Sue has lost her watch. She think it may be at Ann’s house.
SUE: I think I left my watch at your house. Have you seen it?
(1) ANN: no, but I’ll have a look when I get home. If I find it, I’ll tell you.
If I find…。, I’ll……
(2) Ann says: If I found a wallet in the street, I’d take it to the police.
If I found……, I’d(=I would)……。.(而不是if I find, I’ll…。.)
这里两个句子有着不同的意思,前者表示Ann觉得她有找到手表的真实可能性。因此才说if I find…。., I’ll…。.
而后者是完全不同的情况。在这里Ann没有考虑真实的可能性;她在虚拟这一个情景,并不认为真的可以在街上拣到手表。于是才说:if I found……,I’d……
if I do………。和if I did………的区别
用if+过去式(if I found / if you were / if we didn’t等) 表示虚拟的事情,而不是指过去时间发生的事情:
What would you do if you won a million pounds?
I don’t really want to go to their party, but I probably will go. They’d be offended if I didn’t go
Sarah has decided not to apply for the job. She isn’t really qualified for it, so she probably wouldn’t get it if she applied.
If从句中一般不用would:
I’d be very frightened if somebody pointed a gun at me.(而非if somebody would point)
If I didn’t go to their party, they’d be offended(而非if I wouldn’t go)
If …….would可以表示用来请求某人做某事:
I would be grateful if you would send me your brochure as soon as possible.
“Shall I close the door?” “yes, please, If you would.”
Would(‘d) / wouldn’t用于句子的主句(不是if从句)
If you took more exercise, you’d (=you would) probably feel healthier.
Would you mind if I used your phone?
I’m not tired enough to go to bed yet. I wouldn’t sleep.
另外,if引导的条件句也能引起倒装,如果要是在作文里用到,也是一个加分点:
先看正常语序。
