状语从句归纳总结：（as用法） 一、时间状语从句： 1、连接词when、while、as ⑴when ①正当…时候be about to …ving… ②从句动词先于或后于主语动作 ⑵while: 可表示对比（从句只用连续性动词） ⑶as: “一边一边”“随着” 省略句中: eg: As time goes on…随着时间的推移 As a boy,hewao hopeless at English. 2、before,after before常用句型:It is/was/will be…before eg: It will be 5 years before we meet again. 3、till，until ①用于肯定句中“直到…为止”，主句谓语为持续性动词 ②用于否定句中“直到…才”，主句谓语为短暂性动词（until,till可用before代替） ③Not until位于句首倒装 ④强调句型只用until 二、地点状语从句:where,wherever,everywhere 也可引导定语从句： 状语从句：We shall go where the condition are poor. 定语从句：We shall go the place where the condition are poor. 三、原因状语从句 1、because\since\as ⑴①用why提问 ②强调句中 ③关联词“not…but” ④与“just”等副词连用eg:You shouldn’t any only because you had much. ⑵since引导从句常放句首，往往表示对方已知的让步原因关系，主从时态一般相同 ⑶as从句放句首 2、now(that) 既然 3、considering that,seeing (that):与since,now that意相近: “鉴于…”“考虑到…” 4、not that…,but that…“不是因为…而是因为…” 四、目的状语从句 1、that,so that,in order that“为了，以便” ⑴从句中往往出现情态动词：can\could\may\might ⑵当主从句的主语一致时，可转换为相应动词不定式结构：so as to\in order to 2、in case,for fear that,lest“以防、以免、万一..”从句是肯定句 五、结果状语从句 1、so,that,so that
一、方式状语从句 1、方式状语从句通常由as, (just) as…so…, as if, as though引导。 1）as, (just) as…so…引导的方式状语从句通常位于主句后，但在(just) as…so…结构中位于句首，这时as从句带有比喻的含义，意思是"正如…"，"就像"，多用于正式文体，例如： Please do as what I told you.请按照我告诉你的做。 As water is to fish, so air is to man. 我们离不开空气，犹如鱼儿离不开水。 Just as we sweep our rooms, so we should sweep backward ideas from our minds. 正如打扫房屋一样，我们也要扫除我们头脑中落后的东西。 2）as if, as though 两者的意义和用法相同，引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，表示所说情况是事实或实现的可能性较大。汉译常作"仿佛……似的"，"好像……似的"，例如： He looks as if (as though) he had been hit by lightning. 他那样子就像被雷击了似的。（与事实相反，谓语用虚拟语气。） It looks as if the weather may pick up very soon. 看来天气很快就会好起来。（实现的可能性较大，谓语用陈述语气。） 说明：as if / as though也可以引导一个分词短语、不定式短语或无动词短语，例如： He cleared his throat as if to say something. 他清了清嗓子，像要说什么似的。 The waves dashed on the rocks as if in anger. 波涛冲击着岩石，好像很愤怒。 2、其他的引导词 1）the way：Please pronounce the word the way I do.请照我这样,读这个单词. 2）口语常用的like：He sit there smiling like it was his birthday.他面带微笑坐在那儿,像是过生日似的. （这里用了虚拟语气，值得注意的是be动词用的was，而表示虚拟as if引导的be动词则只能是were。） 地点状语从句表示地点、方位，这类从句通常由where，wherever引导。例如： Where there is a will, there is a way. 有志者，事竟成。 They will go where they are happy. 他们想到他们觉得快乐的地方去。 二、地点状语从句 1、地点状语从句类型 1）Where＋地点从句。此句型通常译成“哪里……哪里就……”或“····的地方”。例如：Where there is no rain, farming is difficult or impossible.在没有雨水的地方，耕作是困难的，或根本不可能的。 They were good persons. Where they went, they were warmly welcomed. 他们都是好人。因此他们走到哪里都受到热烈欢迎。 You should have put the book where you found it. 你本来应该把书放回原来的地方。We must camp where we can get water. 我们必须在能找到水的地方露营。 2）Anywhere/ wherever＋地点从句，＋主句。 anywhere本身是个副词，但是，常可以引导从句，相当于连词，意思相似于wherever, anywhere 引导的从句可位于主句之前，也可以位于主句之后。而wherever本身就是个连词，表示“在何处，无论何处”。例如： Wherever the sea is , you will find seamen.有海就有海员。 2、地点状语从句与定语从句的区别 二者区别在于分句在句中作什么成分。作状语，则是状语从句；作定语修饰名词，则是定语从句。where引导定语从句时，从句前应有一个表示地点的名词作先行词；而状语

They decided to cancel the trip _____________ nobody was very enthusiastic about it.
引导条件状语从句的连接词主要有：if(如果）、unless（除非）或as long as（只要）等。unless在意思上等于if...not。 一、条件状语从句用法 1、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: If you ask him, he will help you.如果你请他帮忙,他会帮你的。 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。 2、unless = if...not.除非,若不,除非在……的时候 例如：Let's go out for a walk unless you are too tired. =If you are not too tired, let's go out for a walk. Unless it rains, the game will be played.除非下雨,比赛将照常进行。 3、so/as long as只要 例句;You may borrow my book as long as you keep it clean. 只要你保持书的清洁，你就可以把我的书借去。 So long as you’re happy, it doesn’t matter what you do. 只要你高兴，你做什么都没有关系。 二、时态问题 在条件状语从句中，要注意“主将从现”的规定，即主句用一般将来时，从句用一般现在时表示将来时。例句：I will come to see you if I have time. 我有时间，我就来看你。常见考法 对于条件状语从句的考查，多以单选和完形填空的形式，从时态的角度设题，考查学生灵活运用的能力，或从连词的意义角度让大家选择连词。 典型例题：If he ___in half an hour,we ___wait for him. A. won't come ,won't B.won't come ,don't C.doesn't come ,won't D.will come ,don't 解析：本题考查条件状语从句“主将从现”的运用。题干的意思是“如果他一小时后不来，我们将不会等他了”，从“in half an hour”，“一小时后”可知本句说的是未来的事，那么if引导的条件状语从句要用一般现在时表示将来时，主句要用一般将来时。 答案：C 误区提醒 if 既可以引导条件状语从句，表示“如果”，也可以引导宾语从句，表达“是否”。辨别它在这两种从句中的时态是我们经常容易出错的地方。另外，if 和unless的用法也需注意。 典型例题：----I wonder if your wife to the party. ----If your wife _________, so will mine。. A. will go，go B. will go, goes C.goes, will go D. will go, will go 解析：第一句中if表示“是否”，引导宾语从句，用将来时will go；第二句“如果你的妻子去，我的妻子也去”，if引导条件状语从句，用一般现在时表示将来时。your wife，单三人称主语，所以用goes 。 答案：B

初中英语状语从句知识点总结（一） 用来修饰主句中的动词，形容词或副词等而充当状语的从句叫做状语从句。状语从句常用从属连词来引导，与主句连接起来。若置于句末，则前面不加逗号。根据意义和作用，状语从句可分为时间原因条件等几种。下面我们就来分析一下这几种状语从句。 1时间状语从句 时间状语从句常用从属连词when,after,until,as soon as,等来引导。 当主句是祈使句或谓语动词是一般将来时态或情态动词时，其时间状语从句中的谓语动词常用一般现在时态表示将来发生的动作或存在的状态。这就是我们常说的“主将从现”。 如：Please call me when you get there.当你到那时，请给我打个电话。 I will write to you as soon as I arrive in Beijing.我一到北京就给你写信。 <温馨提示>since引导时间状语从句表示“自从…以来”，从句中的动词一般表示动作的起点，用过去时;而主句的动作延续的情况则用一般现在时或现在完成时。常用的句型为： It has been/is+一段时间+since+过去时。 如：I has been/is three years since we met last time.自从我们上次见面，已经三年了。 2条件状语从句 引导条件状语从句的连词或词组有：if(如果),unless(除非),as long as(只要)等。如果主句是将来时，条件状语从句也用一般现在时来表示。 如：I will stay at home if it rains tomorrow.如果明天下雨，我就待在家。 You can’t learn English well unless you wo rk hard. 除非你努力学习，否则是学不好英语的。 <温馨提示>由if引导的条件状语从句，若从句表达的是与现在事实相反的事实，则常用虚拟语气，即用过去时态表示(如果涉及到be动词，一律都用were)。此时，主句则用过去将来时。
状语从句 什么是状语？ 状语修饰动词、形容词、副词或整个句子。 1. Naturally, our grandparents were pleased to get our phone call. 2. We worked hard, from sunrise to sunset. 3. To help my disabled aunt, I spend an hour working in her house every day 4. Seen from a distance, the farmhouse looked deserted. 5. I know how to light a camp fire because I had done it before. 状语的位置比较灵活，可以位于句首、句末或句中。 什么是状语从句？ 状语从句指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。状语从句一般由连词(从属连词)引导，也可以由词组引起。 根据其作用状语从句可分为： 1.时间状语从句 2.地点状语从句 3.原因状语从句 4.条件状语从句 5.目的状语从句 6.让步状语从句 7.比较状语从句 8.方式状语从句 9.结果状语从句 状语从句的时态特点 一般情况下，时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”，用“现在完成时”表示“将来完成时”。 I will call you as soon as I arrive in Beijing. As soon as I have finished this work, I will go home. If he comes back, please let me know. 1．时间状语从句 常用引导词：when, as, while, as soon as, before, after, since , till, until 特殊引导词：the minute, the moment, the second, every time, the day，the instan t, immediately , directly, no sooner … than, hardly …when, scarcely … when I didn’t realize how special my mother was until I became an adult. While John was watching TV, his wife was cooking. The children ran away from the orchard(果园), the moment they saw the guard No sooner had I arrived home, then it began to rain. Every time I listen to your advice, I get into trouble.
