【网络综合 - 托福考试(TOEFL)】大家在举例的时候常常会这么说“如果………”,”假设………..”,即if……… 　　先不说这种举例的好还是坏,就本身的句子而言,很多都是有问题的.　　总结了一些if的用法,大家考前看看　　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. 　　It would be a serious setback, if the talks were to fail.　　If you should need more information, please telephone our main office.　　If Alex had asked, I would have been able to help.　　倒装是要省略if 　　it would be a serious setback, were the talks to fail.　　Should you need more informatio
