2017托福寫作條件句寫法解析

　　導(dǎo)語：托福寫作中適當(dāng)加入一些條件句，會(huì)讓你的句型更多樣化，下面YJBYS小編向大家介紹托福寫作條件句的寫法，歡迎參考!

　　大家在舉例的時(shí)候常常會(huì)這么說“如果………”,”假設(shè)………..”,即if………

　　先不說這種舉例的好還是壞,就本身的句子而言,很多都是有問題的.

　　總結(jié)了一些if的用法,大家考前看看

　　先看兩個(gè)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…..)

　　這里兩個(gè)句子有著不同的意思,前者表示Ann覺得她有找到手表的真實(shí)可能性.因此才說if I find….., I’ll…..

　　而后者是完全不同的情況.在這里Ann沒有考慮真實(shí)的可能性;她在虛擬這一個(gè)情景,并不認(rèn)為真的可以在街上揀到手表.于是才說:if I found……,I’d……

　　if I do……….和if I did………的區(qū)別

　　用if+過去式(if I found / if you were / if we didn’t等) 表示虛擬的事情,而不是指過去時(shí)間發(fā)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從句中一般不用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可以表示用來請(qǐng)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從句)

　　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引導(dǎo)的條件句也能引起倒裝,如果要是在作文里用到,也是一個(gè)加分點(diǎn):

　　先看正常語序.

　　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.

　　倒裝是要省略if

　　it would be a serious setback, were the talks to fail.

　　Should you need more information, please telephone our main office.

　　Had Alex asked, I would have been able to help

　　倒裝句比if-從句更加正式.

　　但是在否定句里面,不可以用縮寫

　　e.g. 來源：考試大

　　Had he not resigned, we should have been forced to sack him(不用hadn’t he…..)

　　再多說一下,在寫作文的時(shí)候,希望大家舉例的時(shí)候能夠?qū)憣?shí)例,因?yàn)閷?shí)例有它的特指性和唯一行,當(dāng)然,如果實(shí)在你沒有經(jīng)歷過,在舉例虛擬一個(gè)場(chǎng)景的時(shí)候, if起頭,就不要弄錯(cuò)了.

　　最后幾天, 練練作文, good luck, I give my best bless to all you guys!
