由连接词if或unless引导的状语从句叫做条件状语从句。在英文中，条件是指某一件事情实现之后（状语从句中的动作），其它事情（主句中的动作）才能发生，通常译作“假如”。（注意：在含有条件状语从句的复合句中，表示将来时态，主句是一般将来时态，从句要用一般现在时[主将从现原则]，并且，切记紧跟着if的那句话是从句。）
条件状语从句（用法）
语法引导条件状语从句最常用的连词是if,由if引导的条件状语从句表示在某种条件下某事很可能发生。如:
1) If you ask him, he will help you.如果你请他帮忙,他会帮你的。
2) If you fail in the exam, you will let him down.如果你考试不及格,你会让他失望的。
另外,if从句还表示不可实现的条件或根本不可能存在的条件,也就是一种虚拟的条件或假设,从句多用一般过去时或过去完成时。如:
If I were you, I would invite him to the party.如果我是你,我会邀请他参加聚会。
I would have arrived much earlier if I had not been caught in the traffic.如果没有堵车,我会到的早一点儿。
那么,除了if之外,是否还有其他连词也可以引导条件状语从句呢?回答是肯定的,不仅有,还有很多。这些词由于出现的频率较小,且用法较复杂一些,所以不如if为大家所熟知罢了。下面就这些词的用法以例句的形式进行一下简单总结。
1、unless conj.除非,若不,除非在……的时候
You will fail to arrive there in time unless you start earlier.如果你不早点动身,你就不能及时赶到那儿。
Unless it rains, the game will be played.除非下雨,比赛将照常进行。
2、on condition(that)...在……条件下,如果 on condition (that)...引导的条件从句是主句事件发生的前提条件或唯一条件。
I can tell you the truth on condition that you promise to keep a secret.我可以告诉你真相,条件是你答应保守秘密。
You can go swimming on condition (that) you don't go too far from the river bank.你只有在不远离河岸的条件下才可以下水游泳。
3、supposing conj.如果,假如 supposing引导的条件从句表示一种假设条件。
Supposing it rains, shall we continue the sports meeting?倘若下雨,我们的运动会还要继续举行吗?
Supposing anything should go wrong, what would you do then?假如出了什么问题,你准备怎么对付?
4、provided conj.假如,除非,以……为条件 provided (that) +从句表示一种假设条件。
whether,if if 和 whether 通用，都表示“是否”的意思。一般来说，后者比较正 式，在口语中前者常用来代替后者。但两者有时具有不同的暗示。用 whether 时，正反两面的选择意义较强，问话人并不在意回答是肯定 还是否定；而用 if 时，则比较强调单方面，即正面，问话人希望得到 肯定的回答。另外，还要注意以下几点：
一、 whether 和 if 都可以与 or not 连用； 但写在一起时， 只能用 whether， 不能用 if。如：
I don't care whether (或 if) it will rain or not．
I don't care whether or not it will rain. (不用 if)
二、在引导宾语从句时，应注意：
1、表示“是否”时，两词都能引导宾语从句。
I wonder if/whether you can examine him now．
2、宾语从句移置句首时，用 whether，不用 if。
Whether it is true or not， I can't say．
3、宾语从句为否定形式时，通常用 if，而不用 whether。
I asked Tom if Mary wouldn’t come．
4、作 discuss 等词的宾语，用 whether 不用 if。
We discussed whether we should buy the gift for him．
三、在下列情况下，只能用 whether，不能用 if。
1、与不定式连用时，只能用 whether．
He can't decide whether to accept or refuse．
2、在介词后，只能用 whether。
Everything depends on whether he is ready．
3、在名词后作同位语时，只能用 whether。
The question whether they ought to stop working was discussed among the workers．
I have no idea whether he is there．
4、引导主语从句时，只能用 whether。
Whether he comes or not doesn't concern me．
5、引导表语从句时，只能用 whether。
What Maria doesn't know is whether there will be enough snow．
四、if 可引导条件状语从句，译作“如果” ，whether 可引导让步状语 从句，译作“不管、无论” 。
If I were you，I would not buy．
Whether he agrees or not，I shall go there．
