導語：託福寫作中適當加入一些條件句，會讓你的句型更多樣化，下面本站小編向大家介紹託福寫作條件句的寫法，歡迎參考!
大家在舉例的時候常常會這麼說“如果………”,”假設………..”,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.
總結了一些if的用法,大家考前看看
先看兩個例子:
[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…..)
這裏兩個句子有着不同的意思,前者表示Ann覺得她有找到手錶的真實可能性.因此才說if I find….., I’ll…..
而後者是完全不同的情況.在這裏Ann沒有考慮真實的可能性;她在虛擬這一個情景,並不認爲真的可以在街上揀到手錶.於是才說:if I found……,I’d……
if I do……….和if I did………的區別
用if+過去式(if I found / if you were / if we didn’t等) 表示虛擬的'事情,而不是指過去時間發生的事情:
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 ……d可以表示用來請求某人做某事:
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用於句子的主句(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引導的條件句也能引起倒裝,如果要是在作文裏用到,也是一個加分點:
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.
但是在否定句裏面,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,在寫作文的時候,希望大家舉例的時候能夠寫實例,因爲實例有它的特指性和唯一行,當然,如果實在你沒有經歷過,在舉例虛擬一個場景的時候, if起頭,就不要弄錯了.
最後幾天, 練練作文, good luck, I give my best bless to all you guys!
