【基本概念】
在英文中，条件是指某一件事情实现之后，即状语从句中的动作，其它事情如主句中的动作才能发
生，通常译作”假如”。条件状语从句就是在复合句中表示主句动作发生条件的状语从句。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，它的意思是“如果”。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。需要注意的是，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，祈使句或情态动词，从句要用现在时态，并服从”主将从现原则”。“主将从现原则”
中，”将”并非指将来时，还指表示将来含义的，跟在if后的为从句。
除此if之外，还有其他一些连词，如：unless, as (so) long as, on condition that, (just)in case, only if, if
only, suppose/supposing (that)，provided/providing (that)等，它们也多少含有“如果”的意思，也可用于引导
条件状语从句。
【高考热点】
1. 条件状语从句是重中之重，可与和时态，语气，倒装和省略结合起来考查。
2. if only和only if的区别。
3. in case引导的条件状语从句和目的状语从句。
4. 引导方式状语从句的as if, as though与引导让步状语从句的even if和even though辨析。
5. 条件、方式以及比较状语从句的引导词之间，与其它从句的引导词之间的意义不同，和同义词之间的用
法不同辨析。
【考点解读】
一、if引导的四种条件状语从句
英语中的if条件句由两部分组成，一个是连词if引导的条件状语从句，一个是表示结果的主句，if从
句可置于主句之前或之后。主从句的谓语动词的时态形式取决于说话者认为结果是否是真是的。条件句分
为零条件句、第一条件句、第二条件句和第三条件句四种，见下表(The 4 Types of Conditionals)：
下面以动词do为例分别讲解if引导的四种条件状语从句。
（一）零条件句/绝对真实条件句(Zero Conditional)
零条件句，又叫绝对真实条件句，用于阐述事实，指陈述的是事实或是科学原理。用来表达在该条件下，结果一定会如此（规则，客观规律、真理等）。结构是：If+主语+do/does，主语+do/does，
即。其从句和主句的谓语动词通常为一般现在时。如：
If ice is heated,it melts.如果冰被加热，就融化了。（表示科学理论的条件句）
If you heat water, it boils. 如果你烧水，水会开。（表示科学理论的条件句）
If the temperature drops to 0 °C, water freezes. 如果温度降至摄氏0度，水就会结冰。（表示科学理
论的条件句）
If I am late for training, my coach gets angry. 如果我培训迟到了，我的教练会很生气。（表示客观
事实的条件句）
I'm happy to go to the party if you come with me.如果你和我一起，我就愿意去参加晚会。（意思是
你去我才去）（表示客观事实的条件句）
In time of serious accidents, if we know some basic things about first aid,we can save lives. 在严重事故
的时候,如果我们了解一些基本的急救常识, 我们可以挽救生命.（表示客观事实的条件句）
If I felt any doubt, I always asked my teachers. 我一有了疑惑，总要问我的老师。（表示现在习惯动
作，其从句和主句谓语动词为一般现在时；如表示过去习惯动作，其从句和主句谓语动词为一般过去
时。）
请注意，在零条件句(即绝对真实条件句)里，主句和从句都使用现在时态，而且连词if相当于
when。
（二）第一条件句/相对真实条件句（First Conditional）
第一条件句又叫相对真实条件句，谈论可能发生的事情, 并考虑这件事情的结果。强调偶然性或
一次性的条件，也可以与绝对真实条件句同义。if从句用一般现在时或其他现在时, 表示可能发生的
事情（条件）；主句用一般将来时, 表示这件事情的结果。结构是：If +主语+do/does，主语+will do。
如：
I will tell him about it if he comes. 要是他来的话，我就把此事告诉他。
I will be happy to go to the party if you come with me. 如果你和我一起去的话，我就会很开心地去参
加晚会。（也就是说你去不去，我都得去）
If you ask him, he will help you. 如果你请求他,他会帮助你。
You will get the full mark if you study hard. 如果你努力学习,你就会得满分。
If ice meets heat, it will melt. = If ice is heated,it melts.
（三）第二条件句（Second Conditional）第二条件句是虚拟条件句的一种，即现在虚拟条件句(Unreal Present)， 用来表达在现在或将来时间下
不太可能或不可能发生的条件，这种条件句还可以用来表示试探性的、委婉的语气（可以理解为不大有自
信, 所以不太真实的条件）。结构是：与将来事实相反的非真实条件句是If+主语+did/should do/were to
do， 主语+would/should/could/might+do; 与现在事实相反的非真实条件句是 If+主语+did, 主语+
would/should/could/might + 动词原形。如：
If I had enough money next month, I would buy a copy of “The Advanced Learner’s Dictionary of Current
English”。如果我下个月有足够的钱，我就会买一本《现代高级英语学习词典》。
If I didn't suffer from a fear of flying, I would travel more. 我要不是晕机的话，我会多出行的。（现在实
际情况是由于晕机出行较少）
If I were you, I would ask our teacher for advice. 如果我是你的话，我就请教老师。
If I wanted you to travel to Tibet with me, would you want to go? 要是我让你跟我一起去西藏，你愿意去
吗？（问话着问的比较委婉）
（四）第三条件句（Third Conditional）
第三条件句是表示与过去事实相反的虚拟语气，是用来表达如果(If)当时那样发生, 另外一方面（当
时）会如何。通常是指过去的事情, 带有一切已经太迟而不能够补救的意思。结构是：If+主语+had done,
主语+would/should/could/ might +have done。如：
If she hadn't been ill, she would have gone to work. 当时她要不是生病就去上班了。（事实是生病了而没
有去上班。）
If he hadn’t been so lazy in college, he would have found a much better job when he graduated. 他要不是读
大学时候那么懒，毕业的时候就找到一份更好的工作了。
If he had studied harder in college, he would have found a much better job when he graduated. 他读大学时候
要是更努力点，毕业的时候就找到一份更好的工作了。
If the Second World War had not broken out, the Cold War might not have come to pass.如果第二次世界大
战没有发生，冷战也不一定会出现。
二、其它引导条件状语从句连词
（一）unless
unless“除非；如果不”，意思同if…not，unless从句的谓语只能用肯定式，一般可以与if…not互换。
而if引导的条件状语从句可以是真实的条件从句，也可以是虚拟条件从句，即虚拟语气。如：Difficulties are nothing if we are not afraid of them.
如果我们不怕困难，困难就算不了什么了。
We shall go there tomorrow unless it rains. = We shall go there tomorrow if it doesn’t rain. 除非下雨，我们
明天就去那里。
【考例1】(XXXX上海卷) our manage objects to Tom's joining the club, we shall accept him as a
member.
A. Until B. Unless C. If D. After
解读：B。此句意思是“除非我们经理反对汤姆加入俱乐部，不然我们都应接受他成为其中一员。”
相当于If our manage doesn’t object to Tom's joining the club,…。用unless引导条件状语从句，故选B。
【考例2】(XXXX 上海卷) Small sailboats can easily turn over in the water ______ they are not managed
carefully.
A. though B. before C. until D. if （选D）
【考例3】（XXXX全国Ⅱ）All the dishes in this menu, otherwise stated, will serve two to three
people.
A. as B. if C. though D. unless
解读：D。考查状语引导词unless。全句意思是：在这份菜单上的所有菜，除非另外说明，会给二到三
个人食用。从句省掉了主语和be动词，补全就是unless otherwise it is stated, …。
（二）as (so) long as, on condition that, in case
as (so) long as“只要……就……”，从句的谓语动词一般不用非延续性动词；on condition that“如果，
在……条件下”；in case“如果发生，如果，万一”。如：
You may borrow this book as (so) long as you promise to give it back.
只要你答应归还，你就可以把这书借走。
You can go there on condition that you don’t come back late for dinner.
你可以去那儿，条件是回来吃饭不能太晚。
Take a hat with you in case the sun is very hot.
倘若太阳很厉害，你就把帽子戴上。
注意：in case引导目的状语从句作“以免，免得，以备，以防”等解。多位于句未，如：1.He takes
a torch in case it gets dark before he returns.他带了手电筒，以备天黑以后回家之用。(为了不摸黑)。
in case还可以引导条件状语从句，意为“如果、万一”。多位于句首，如：1.In case he comes,let
me know.如果他来的话，告诉我一声。【考例1】(XXXX安徽卷）-----Do you have a minute? I’ve got something to tell you.
-----Ok, ______ you make it short.
A. now that B. if only C. so long as D. every time
解读：C。本题考查条件状语从句。由OK可知答话人同意对方和自己说事, 但后面you make it short
在语意上存在转折关系,说明答话人是有条件的,只有so long as"只要"能表达出这种含义。故选C。
【考例2】（XXXX全国I卷）—Have you got any idea for the summer vacation?
—I don’t mind where we go ______ there’s sun, sea and beach.
A. as if B. as long as C. now that D. in order that
解读：B。“我不介意到哪里去”的前提条件是“只要有阳光、海洋和沙滩”就行，换句话说如果没
有这些就会介意。故选B。
【考例3】（XXXX江西卷）— Our holiday cost a lot of money.
— Did it? Well, that doesn’t matter______ you enjoyed yourselves.
A as long as B unless C as soon as D though
解读：A。as long as只要 unless 除非否则 as soon as 一就 though虽然, 后一句为只要你玩的开心, 花
多少钱就不重要。
【考例4】（XXXX陕西卷）My parents don’t mind what job I do I am happy.
A. even though B. as soon as C. as long as D. as though
解读： C。根据题干意思可知此处是条件状语从句，引导词意思是：只要，选 C。even though引导让
步状语从句，意思是：即使；as soon as引导时间状语从句，意思是：一……就……；as though引导方式状
语从句，意思是：仿佛，好像。
（三）only if, if only
这两个结构十分相似，但是用法却截然不同。only if引导的从句用陈述语气，意思是“只要”，当从
句在句首通常要求用部分倒装语序。if only引导的从句用虚拟语气，意思是“要是……就好了，但愿”。
Only if we persist in carrying out the open-door policy, will we achieve greater success in every field.
只要我们坚持改革开放，我们就能在各个方面取得更大的成就。
If only I had known it, I wouldn’t have troubled him.
要是我早知道那件事情，我就不会麻烦他了。
【考例】（XXXX江苏卷）______ you eat the correct foods ______ be able to keep fit and stay healthy.
A. Only if; will you B. Only if; you will
C. Unless; will you D. Unless; you will （选A）（四）suppose/supposing (that)，provided/providing (that)
这组连词的形式看起来很别扭，因为 suppose形式是一个动词原形，给人以祈使句的感觉，其余的是
分词结构，会不由自主的联想到非谓语动词作状语要求与句子的主语保持逻辑上的一致。其实他们已经成
为连词，引导条件状语从句，所以用法上就遵照连词的使用规则。suppose/supposing (that)的意思是“假
定”，常用来提出一个假设的条件，询问肯呢过出现的情况或者解决的办法，因此其主句多为疑问句。
provided/providing (that)的意思是“在……条件下， 以……为基础”，主句的内容只有在该条件满足的情
况下，才能成为事实。接近于on condition that。如：
Supposing his plan goes wrong, what will we do then?
如果他的计划出了问题，我们怎么办？
Suppose you lost your job tomorrow, what would you do?
假定你明天失业，你怎么办？
She agreed to go and work there provided that her family could go with her.
如果她家人能随她同行，她同意去那里工作。
I'll dry the dishes, providing that you do the washing-up.
如果你刷盘子，我就把它们擦干。
典题：You may keep the book a further week______ no one else requires it.
A. whenever B. as if C. so that D. provided that
D。根据情态动词may表示的许可，可以看出后面是条件状语从句，provided that引导条件状语从句相当于
if。故选D。句意是：倘若这本书没有其他人想借的话，你可以再续借一个礼拜。
三、条件句的另外两种表达方式：
1. “the more…the more…”。
表示“越……越……”，句型前部是条件，后部是结果。如：
The closer you stay to nature, the more you will appreciate her beauty. = If you stay closer to nature，you
will appreciate her beauty more. 你愈接近大自然，就愈能了解它的美。
The colder the weather (is), the my life (will be). = If the weather is colder, my life will be more
comfortable.天气愈冷，我的生活就愈舒服。
考例： (XXXX上海) As far as I am concerned, education is about learning and the more you lean, ____.
A.the more for life are you equipped B.the more equipped for life you are
C.the more life you are equipped for D.you are equipped the more for life解读：B。根据the more you learn，结合备选项确定是“the+形容词(副词)的比较级+陈述句，the+形容词
(副词)的比较级+陈述句”句型，表示“越……越……”。译文：我认为，教育是关于学习的事，你学得越
多，你对生活准备得就越充分。the more equipped for life的意思是 “对生活有充分的准备”。
2. “祈使句+and(or)+陈述句”句型。
表示“如果……就……”。祈使句相当于if引导的条件状语从句，陈述句部分表示结果。如：
Study hard and you will make progress. = If you study hard, you’ll make progress.
要是你努力学习，你就会取得进步。
三、条件状语从句考点设置
（一）考查条件状语从句的时态
条件状语从句的谓语动词通常不用一般将来时，需要的时候要求用一般现在时代替。但是可以用情态
动词will/would表示意愿，甚至可以用这种方式提出请求。如：
If you will wait a moment, I’ll go and tell the manager that you are here.
你要是愿意稍等一会儿的话，我就告诉经理你在这里。
If you would lend me $5 until Monday, I would be grateful.
要是你愿意借给我5元一直用到星期一，我会非常感激的。
【考例】That's why I help brighten people's days. If you ________, who's to say that another person will?
（XXXX·湖南卷）
A. didn't B. don't C．weren't D．haven't
【答案与解析】B。根据主句的another person will可以看出表示将来的动作，但是在条件状语从句中
常要求用现在时表示将来的动作。故选B。句意：这就是我为什么为别人的生活增添乐趣。如果你不这样
做的话，天知道还会有谁这样做。
（二）考查条件状语从句与其它从句的区别
除了条件状语从句，还有时间、让步、方式、比较、原因、结果等状语从句，通过引导词本身就可以
区别出所引导的不同状语从句。由于状语从句与其它从句区别比较明显，因此在考题中对于其与名词性从
句、定语从句的区别考查比较少。
【考例1】You won’t find paper cutting difficult _____ you keep practicing it.（XXXX·北京卷）
A. even if B. as long as C. as if D. ever since【答案与解析】B。keep practicing是won’t find paper cutting difficult的条件，因此是条件状语从句，
故选B。A. even though“即使，虽然”，引导让步状语从句；B. as long as“只要...
...就......”，引导条件状语从句；C. as if“犹如，好像”，引导方式状语从句或表语从句；D. ever since“自
从”，引导时间状语从句。
【考例2】I'll be out for some time. ______ anything important happens, call me up immediately. (XXXX·四
川卷)
A. In case B. As if C. Even though D. Now that
【答案与解析】A。anything important happens是一种假设，要是有就call me up immediately，要回没
有就不必要了。in case有“万一”的意思，引导条件状语从句，故选A。as if引导方式状语从句或表语从
句；even though引导让步状语从句；now that“既然”，引导原因状语从句。
【考例3】You will never gain success_______ you are fully devoted to your work. (XXXX·湖南卷)
A. when B. because C. after D. unless
【答案与解析】D。fully devoted to your work是gain success的条件，否则就不会取得成功，因此从句
有if you aren't fully devoted to your work意思，if ...not...则相当于备选项中的unless，故选D。A和C引导
时间状语从句；B引导原因状语从句。句意是：除非你全身心的投入到工作中去，否则你永远都不会获得
成功。
（三）考查条件状语从句引导词的区别
引导条件状语从句的连词有if, unless, suppose, so/as long as, in case等。其中unless相当于if...not。
【考例】You can borrow my car ________ you promise not to drive too fast.（XXXX·江西卷）
A. unless B. if C. in case D. as long as
【答案】D。主句是肯定句，表示结果，而这一结果是建立在promise not to drive too fast的基础上，as
long as表示具有充分的条件, 正句常用“就”、“也”、“都”、“便”相呼应，表明由这种条件产生的
一种结果，而if表示的是一种假设的条件。如果选unless，前面要用否定句，即You can't borrow my car
unless you promise not to drive too fast.。in case强调“万一”出现的情况。故选D。
（四）考查条件状语从句中的省略
条件状语从句的主语与主句的主语一致时，可以根据省略为“if+现在分词/过去分词/形容词/副词
等”。
【考例1】Video games can be a poor influence if ________ in the wrong hands.（XXXX·湖南卷）
A. to leave B. leaving C. leave D. left【答案与解析】D。当条件状语从句的主语与主句的主语一致且从句中含有be动词的某种形式时，可
以省略状语从句的主语和be 。此题的形式属于：连词(when, if, even if, unless, once, until, than, as ) + 过去
分词 。完整的句子就是：Video games can be a poor influence if they are left in the wrong hands.。句意：电
子游戏一旦落入错误之手，就会产生不良影响。
【考例2】It is so cold that you can’t go outside _____ fully covered in thick clothes.（XXXX·江苏卷）
A. if B. unless C. once D. when
【答案】B。根据go outside和fully covered in thick clothes可以看出是“条件→结果”关系，排除C和
D。都用否定时you can’t go outside则对应的是you aren't fully covered in thick clothes, 而unless有if...not...
的含义，故选B。本题是“连词+过去分词”结构，省略了从句的主语和主语后的动词be。
【考例3】（XXXX山东卷）The school rules state that no child shall be allowed out of the school during
the day, ______ accompanied by an adult.
A. once B. when C. if D. unless
解读：D。句意应为“学校规章规定：除非有成年人陪同，否则孩子们在校期间不能出学校。”表示“除
非”用unless。该句式构成了“连词+过去分词”结构。
