状语从句之条件状语从句：知识点总结+习题 (Word版,无答案)
状语从句之条件状语从句：知识点总结+习题（Word版，无答案）状语从句——条件状语从句一、条件状语从句的引导词：条件状语从句由if, un le ss( 如果不), as/so long a s( 只要), suppos i ng( 假设), suppose that( 假设), given that( 如果), in case( 万一), on condition that( 如果), provided that(假如)等词引导。
注意：在条件状语从句中，通常用一般现在时表示将来，用一般过去时表示过去将来。
二、真实条件状语从句与非真实条件状语从句：if 既可以引导一个真实条件状语从句又可以引导一个非真实条件状语从句，两者主要在以下三个方面有所不同：⑴意义及谓语动词形式不同：如果该条件纯属假设，谓语动词用虚拟语气；如果是有可能实现的条件，则使用动词通常的陈述形式。
①非真实条件状语从句的谓语动词用动词过去式来表示与现在事实相反或难以实现的愿望，主句则用“would+动词原形”；而真实条件状语从句得到谓语动词用动词的一般现在时表示一般或未来情形下的条件，主句用一般现在时或将来时。
试比较：e.g.: If my husband were a woman, he would understand my feelings a bit better. 如果我丈夫是女人的话，他就会更好的理解我的感情了。
（丈夫不可能是女人）Oil floats if you pour it on water.如果你把油倒在水上，它就能漂浮在上面。
（能实现的事实）②非真实条件状语从句的谓语动词用“had+过去分词”表示与过去的事实相反，主句用“would have done”；真实条件状语从句用一般过去时指过去的事实或用于间接引语中（可表示过去将来的情况），主句用一般现在时或过去将来时。
试比较：e.g.: If I had been a teacher at that time, I would have argued with him.当时我要是老师的话，就和他争辩了。

状语从句考点+例题-全面解析（word）一、初中英语状语从句1．--Where is the comic book?--I brought it to you ________you were in the reading room yesterday.A．when B．if C．because D．before【答案】A【解析】句意：-漫画书在哪里？-昨天当你在阅览室的时候我就拿给你了。
when当…时候；if如果，引导条件状语从句；because因为，引导原因状语从句；before在…之前，引导时间状语从句。
根据句意可知，这里表示“当你在阅览室的时候”，故应选A。
2．---Mom, shall we have supper now?---Oh, we won’t have supper_______ your dad comes back.A．until B．since C．while D．after【答案】A【解析】试题分析：句意：-妈妈，我们现在吃晚饭好吗？ -哦，直到你爸爸回来我们才可以吃晚饭。
until直到；since自从；while当……的时候；after在……之后。
Not…until直到……才，是一个固定句型，所以选A。

3．—I don ' t know if Sam tomorrow.—Don't worry. I will tell you as soon as he .A．will come; comes B．comes; will comeC．will come; will come D．comes; comes【答案】A【解析】【详解】句意：——我不知道萨姆明天是否会来。
——别担心，他一来我就告诉你。
第一个句子为if引导的宾语从句，根据从句中的时间状语tomorrow判断，从句的时态为一般将来时，排除B,D；第二个句子是as soon as引导的时间状语从句，遵循“主将从现”的原则，本句的主句是一般将来时，as soon as引导的从句要用一般现在时，故答案为A。
(完整word版)状语从句语法口诀
英语语法口诀第一部分定语从句1.定语从句概述a)定语从句起定语修饰作用，分为限定性和非限定性两种，非限定性通常有逗号验证I have plenty of friends who are from foreign countries.I have plenty of friends, some of whom are from foreign countries.b)先行词，关系词，定语从句，如此一线性The man that instructed me is a famous expert.c)关系词分为关系代词和关系副词两种，关系代词作主宾表定，关系副词作状语才行：关系词三大作用：1.代替先行词；2.引导从句；3.在从句中充当成分The murder was caught alive in the house where he killed three women.2.三步法选关系词a)首先找出先行词，带入从句看成分是其次，（主表宾定不合适，状语必然是，用关系副词）再由先行词及其成分定关系词I will never forget the day when I met the president.3.关系代词的选用a)人用that whom who。
b)which that 用于物c)that 真是个人物，既充人又充物；既当宾又当主d)whom 只做宾，which that who 既宾又主e)whose 作定语（=名词+of which），不分人或物The tall house whose windows face the south is my office.4.关系副词的选用a)先行词the time，需用关系副词时，用when 才可以若关系词在从句中充当状语，则关系词应用when，the time +when（=on which）I will never forget the days when I lived with you happily.I will never forget the days which I spent learning English .b)先行词the place，需用关系副词时，where来效力若关系词在从句中充当状语。
状语从句考点解析(Word版附答案)
在if引导的条件状语从句中，if和条件句位置灵活，可直接放在主句后面，若if条件句放句首，从句后面要加逗号，和主句隔开。还要注意前后时态一致原则。
2．—I’m going to the post office.
—________you are there, can you get me some stamps?
15．----Mike wants to know if ________ a picnic tomorrow.
---- Yes. But if it ________, we will visit the museum instead.
A．you have; will rainB．you will have; will rain
If it rains tomorrow, we will not go to the zoo.
What will you do if you find a panda in danger.
如果if条件句谈论的是重复发生和预示要发生的情景和事件，则主从句大多用一般现在时态。如：If bears are in danger, they attack people.
9．If the kids stay indoors all the time and get no exercise, they _________ weak.
A．becomeB．have becomeC．will becomeD．became
【答案】C
【解析】
【详解】
句意：如果孩子们一直呆在室内并且得不到锻炼，他们将变得很虚弱。If引导的条件状语从句主句用一般将来时，从句用一般现在时，结合语境故选C。
考点：考查连词。
(完整word版)状语从句(完整归纳)
状语从句一．分类：种类连接词注意区别：时间状语when/whenever/while/as/before/after/instantly/until/till/by the time/as soon as/hardly…when/directly/no sooner…than/the moment/the minute/immediately有一些表示时间的名词短语也可用来引导时间状语从句：the minute, the moment, every time, the first time例：The moment he reached the country, he started hissearch. 他一到达这个国家，就开始他的探寻工作。
有一些表示时间的副词也可用来引导时间状语从句：directly例：Directly the master came in, everyone was quiet.校长一进来，大家就安静下来as和when、while：as, when 引导短暂性动作的动词。
当从句的动作发生于主句动作之前，只能用when 引导这个从句，不可用as或while。
从句表示"随时间推移"连词能用as，不用when 或while。
till/until和not…till/until：Until可用于句首，而till通常不用于句首。
地点状语where//wherever where，表示某一个；wherever，表示任何一个。
原因状语Because/as/since/now that/forbecause和since、for、as、now that：because语势最强，用来说明人所不知的原因，回答why提出的问题。
当原因是显而易见的或已为人们所知，就用as或since。
由because引导的从句如果放在句末，且前面有逗号，则可以用for来代替。
但如果不是说明直接原因，而是多种情况加以推断，就只能用for。
