在日常學習、工作或生活中，大家總少不了接觸作文或者范文吧，通過文章可以把我們那些零零散散的思想，聚集在一塊。那么我們該如何寫一篇較為完美的范文呢？下面我給大家整理了一些優(yōu)秀范文，希望能夠幫助到大家，我們一起來看一看吧。
if引導的條件狀語從句例句篇一
例如：
if i am free, i will come to see you.
= i will come to see you if i am free.
如果我有空，我就來看你。
2、 在含if引導的條件狀語從句的復合句中，主句用一般將來時，從句通常用一般現(xiàn)在時態(tài)表示將來意義，即“主將從現(xiàn)”原則。
例如：
if it snows tomorrow, we will go skiing.
如果明天下雪，我們就去滑雪。
3、 在含if引導的條件狀語從句的復合句中，語句的謂語還可含有情態(tài)動詞can、must、may等，主句也可是祈使句。
例如：
if it stops raining, we can go out.
如果雨停了，我們就能出去。
4、 在含if引導的條件狀語從句的復合句中，如果主句部分描述的是客觀事實或真理，要用一般現(xiàn)在時。
例如：
if you heat the ice, it turns into water.
如果你加熱冰，它就會變成水。
if引導的條件狀語從句例句篇二
對過去的虛擬
條件從句(if):主語+had done 主句might/would/should/could+have done
對現(xiàn)在的虛擬
if+ 主語+動詞過去式(be用were)主句 might/would/should/could+do
對將來的虛擬
if+主語+動詞過去式(be用were)或主語+should do或主語+were to do
主句 might/would/should/could+do
e.g.
tom got to the station in time because he started earlier.
if tom had started late, he would have missed the train.
do you think the thief entered through the door?
no, if he had, i dont believe, he would have broken the living room window.
if the book werent so expensive, i would buy it.
if you didnt live so far away, we would be able to visit you more.
what would you do if you lost your passport in a foreign country?
why hasnt he come? if he should not come on time, we would have to put off the trip.
2、注意事項
e.g.
if she hadnt work hard at english in the past, she wouldnt work as well as a secretary in a large company now. 混合時間的虛擬語氣 從句為對過去的虛擬，主句是現(xiàn)在。
had we not used an out-of-date timetable, we wouldnt have missed the train.
if引導從句的倒裝從句相當于 if we had not used an out-of-date timetable, 同樣，were還有should 在從句中都可以提前，省略if.
if only 要是。.。就好了
if only i were younger!
if only i had worked harder in my teenage years!
if only i should travel tomorrow!
