比较状语从句讲解和练习题
比较状语从句：
状语从句指句子用作状语时，起副词作用的句子。比较状语从句是其中的一种，主要运用于形容词和副词的原级、比较级及最高级的句子之中。原级：as…as （和……一样），not so（as）…as …（和不一样）；比较级：more…than（更）；最高级：The most…in/of， the + 形容词+est…of/in。常用引导词：as（同级比较），than（不同程度的比较）；特殊引导词：the more … the more … ；just as …，so…；A is to B what /as X is to Y；no … more than；not A so much as B。
比较状语从句通常由as或than引起，这类从句和大多数状语从句不同，它们不修饰动词，而是修饰as，so，less，more等副词，或其他比较级的词，如taller， harder．在这里讨论它们，不是作为动词修饰语，而是作为一种状语从句。包含这类从句的句子通常为L，即从句在后：She is as tall as I（or me）．
He works as hard as his brother（does）．
He does not work as hard as his brother．
He does not work so hard as his brother．

She thinks more about her appearance than（she thinks about）her personality．
She finds it easier to read than to write．
She is not taller than I．（Both are tall．）
She is no taller than I．（Both are short．）注意这两句话的区别。

I can forget her no more than she（forgets）me．
Nothing is more dangerous than that you （should）make friends with him．

Than him nobody is more clever．（= He is the cleverest man．）（than在这里的作用更接近介词）

I know John，than whom I have never seen a sillier man．

原因状语从句的用法
原因状语从句的用法 原因状语从句表原因，以下逐一介绍高考中常见的原因状语从句的引导词： 1. because引导的原因状语从句一般放于主句之后， because表示直接原因，语气最强，最适合回答 why引导的疑问句。例如： I do it because I like it. 我做这件事是 因为我喜欢。 注意：“not ... because”结构中的not否定的是because引导的整个从句，有时也否定主句例如： The country is not strong because it is large. 国强不在大。I 2. since引导的原因状语从句一般放于主句之前表示已知的、显然的理由(通常被翻译成“既然”)，较为正式，语气比because弱。例如： Since you are free today, you had better help me with my mathematics. 既然今天你休息，你最好帮我补习数学。 注意： seeing (that)， now (that)， considering (that)， in that这几个词汇与since引导的原因状语从句意思相近，都表示“既然”。例如： Seeing (that) he refused to help us, there’s no reason that we should now help him. 他既然曾经拒绝帮助我们，我们现在没有理由要来帮助他。// Now (that) you are grown up, you should not rely on your parents. 既然你长大了，就不应该依靠你的父母了。// Considering (that) everyb ody is here, let’s begin our discussion. 既然大家都到了，我们就开始讨论吧。// In that he is ill, he feels unable to do it. 因为有病，他觉得做不了那件 事。注意： 1. considering 和 given 还可用介词。如： Considering his age, the little boy reads very well. 就他的年龄来说，这小孩读得 挺好的。 Given her interest in children, I am sure teaching is the right career for her. 考虑到她喜欢孩子, 我可以肯定教书是最适合她的职业。 2. 表示“因为”的连词不能与表示“所以”的 so 连用。如： 译：因为他病了，所以没有出席会议。 误：Because he was ill, so he didn’t attend the meeting. 正：He didn’t attend the meeting because he was ill. 正：He was ill so he didn’t attend the meeting 3. as 引导原因状语从句时表示附带说明的“双方已知的原因”，语气比since弱，较为正式，位置较为灵活(常放于主句之前)。例如：As it is raining, you’d better take a taxi. 既然在下雨，你最好乘出租汽车。// As you are tired, you had better rest.

中考英语状语从句考点归纳与例析 【重点讲解】 中考英语试题对状语从句的考查主要涉及引导状语从句的从属连词的用法。单项选择题的四个选项往往是四个连词，这是状语从句最常见的考查形式。另一个考点是状语从句中的时态，因此，在学习状语从句时要弄清状语从句的几个主要类别，如时间、地点、原因、条件、让步、方式、目的、结果等，同时记住它们的“引导词”及其相关意义。 考点一：引导状语从句的连词的选择。 1、引导时间状语从句的连词主要有when, while, as, by the time, before, after, since, till/until, as soon as等。其中when，while和as都可表示"当……时候"，但用法有区别: when意为"在……时;当……时",可表示"点时间"或"段时间",从句谓语可以是终止性动词,也可以是延续性动词。例如: When I got home, he was having supper. as意为"边……边……"或"与……同时",重在表示两个动作同时发生。伴随进行。as从句是终止性动词时,主句通常也必须是终止性动词。例如: They sang as they danced. while只可表示"段时间",从句谓语只限于延续性动词。例如: While I was sleeping, my father came in. 注意：从句谓语是持续性动词时,when，while和as可以互换。主、从句谓语都是终止性动词时，when与as可互换。从句谓语表示状态时，通常用while。 2、引导地点状语从句的常用连词是where。例如： Where there is a will there ia a way. 3、引导原因状语从句的连接词主要有because, as, since, for。例如： Tom was late for school this morning because he didn’t catch the early bus. As he was not well,I decided to go there without him. Since this method doesn't work, let's try another. for表示所说的理由是一种补充说明，因此, for引导的从句一般不放在句子的开头。例如: I decided to stop and have lunch, for I was feeling quite hungry. 注意：because语气最强，as, since, for次之。对于以why开头的问句，一般要用because引导的从句来回答。 4、引导条件状语从句的连接词主要有if, unless, as long as。例如： If I am not busy tomorrow, I will play football with you. Unless you tried it, you can’t imagine how pleasant it is. 5、引导让步状语从句的连接词有although, though, even if, even though。例如： Although (though) I gave him some advice, he didn’t take them.

地点状语从句 常用连词：where 特殊连词：wherever (在……的任何地方), anywhere, everywhere 【点拨】地点状语从句与定语从句的区别：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；而状语从句前则无需先行词。 Go back where you came from.(where引导地点状语从句)你从哪儿来回哪儿去。Go back to the village where you came from.

(在一段时间内) 我们在学校上学的时候，每天都去图书馆。 We were about to leave when he came in.我们刚要离开，就在那时他进来了。 2) while引导的从句的谓语动词必须是延续性的，并强调主句和从句的动作同时发生(或者相对应)，此外，while有时还可以表示对比。 I like playing football while you like playing basketball. 我喜欢踢足球，而你喜欢打篮球。(对比) He fell asleep while/when reading.看书的时候，他睡着了。 Strike while the iron is hot. (用as或when不可以，这里的while意思是“趁……”) 趁热打铁。 3) as表示“一边……一边”，as引导的句子的动词是延续性的动词，一般用于主句和从句动作同时发生；as也可以强调一先一后。 We always sing as we walk.我们总是边走边唱。(as表示“一边……一边”) Our headmaster laughed as she spoke.我们的校长边谈边笑。 2．由before“在……之前”和after“在……之后”引导的时间状语从句。 It will be four days before they come back．他们要过四天才能回来。 My father had left for Canada just before the letter arrived. 我父亲恰好在信到之前去加拿大了。 After you think it over, please let me know what you decide. 你仔细考虑过以后，请告诉我你是怎样决定的。

时间原因条件状语从句
掌门1对1教育高中英语 时间、原因、条件状语从句 一．when, while 和as 引导时间状语从句的区别用法（一）when 的用法when 从句的A事件，相当于另一个事件B发生的时间点。（也就是说，when 从句的重点不在动作本身发生的状态，而只是把它作为一个时间点，）所以when 多数情况下用的是一般过去时，则不用正在进行时。（口头练习） When I got to the airport, the guests had left. Why do you want a new job when you have got such a good one already? (二)while 的用法 while 从句的侧重点在于描述动作正在发生的状态，（它的意思是：当while 事件正在发生的时候，另一件事如何如何。）所以，while 从句一般用的是正在进行时。而另一件事的状态根据具体情况而定。（口头练习） 1. While my wife was reading the newspaper, I was watching TV. 2. While Jim was mending his bike, Lin T ao came to see him. 从时间的角度来看，while 表示的是一段时间，是一个过程。 趁热打铁。Strike while the iron is hot.（这句话中，是说趁着铁是热的这段时间，赶紧打铁。如果换成when 意思就变了，相当于说铁只热了一下，打一下，然后铁就冷了。这显然不符合文意。） (三)as 的用法 as 从句表示的也是一件事情正在发生，另一件事也正在进行当中。as 从句用的一般不用正在进行时，而只是一般过去时。可以翻译成“边……边……”。（口头练习） As my mother sang those old songs, tears ran down her cheeks. The students took notes as they listened. as 表达的事件，往往只是主句动作发生的背景或条件时，as 只是一个次要的时间说明，常常翻译成“随着……”之意。 1. As the time went on，the weather got worse. 随着时间的推移，气候更加糟糕。 2. The atmosphere gets thinner and thinner as the height increases. 随着高度的增加，大气越来越稀薄。（少数情况下，如果强调动作正在发生，as 从句也可以用正在进行时。The sad mother sat on the roadside, shouting as she was crying. 伤心的妈妈坐在路边，边哭边叫喊。）
状语从句用法讲解和练习
第章状语从句 学习指导 状语从句在句子中作状语，用来修饰主句或主句的谓语。一般可分为九大类,分别表示时间、地点、原因、目的、结果、条件、让步、比 较和方式。尽管种类较多,但由于状语从句与汉语结构和用法相似,所 以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词。现分别列举如下: 状语从句分九类： 在这一章节的学习中，要求同学们掌握各类状语从句基本概念，并能够灵活应用。 第一节时间状语从句 时间状语从句用一般现在时表示将来。连接时间状语从句的连接词有：2．when，while，as均可表示“当……的时候”。 when强调“特定时间”，表示主句谓语动词的动作与从句谓语动词的动作是同时发生的，或从句的动作发生在主句的动作之前；while表 示的时间是一段，而不是一点，as多用在口语中，强调“同一时间”或“一前一后”，有时还有“随着”的含义。 When spring came, he felt like a trip.春天来了，他想去旅游。 As spring warms the good earth，all flowers begin to bloom．(as有“随着”的含义) as, when, while都表示主、从句的动作或状态同时发生，但三者也有
区别。as和when引导的从句既可表示一点时间，也可表示一段时间，从句中的谓语动词既可以是持续性动词，也可以为短暂性动词，经常可以互换使用；while引导的从句通常表示一段时间，从句中宜用持续性动词作谓语。当从句中的谓语动词为持续性动词时，这三者可以通用（前面例句中已有体现），再如： 1 / 18 Mother was worried because little Alice was ill, especially as / when / while father was away in France.妈妈担心，因为小艾丽思病了，特别是当父亲远在法国的时候。 如果从句和主句要表示一个人的两个动作交替进行或同时完成时，则多用as，可译为“一边......，一边......”。例如： He looked behind from to time as he went.他一边走，一边不时地往后看。 As time goes on, it's getting warmer and warmer..随着时间的推移，天气变得越来越暖了。 I thought of it just as you opened your mouth.你一张嘴我就知道你要 说什么。（若表示两个短促动作几乎同时发生时，用as的场合多于when.） 当主从句之间表示转折或对比关系时，多用while, 不用as或when。如：

状语从句高考考点高考状语从句讲解 语法专题 状语从句 考点归纳 考点一：对when，while，as，since等词的辨析 when，while，as，since在引导时间状语从句时的区别可参见下表： 和从句动词所表示的动作或状态是同时发生的，它引导的从句用延续性动词，若从句中是非延续性动词，不能用while。 表示“一边……一边”的意思时用as或while。 As/While she was cooking she was singing songs、 She sang as she cooked、 当主句谓语动词表示短暂动作，而从句动作可以持续一段时间时，三个连词都可以用。 Tom poke his leg while/when/as he was playing football、注意： ① when也可用作并列连词，其意义为“就在那时，这时”，相当于and at this/that time，常用下列句式中： We were having a meeting when someone poke in、 We were about to set off on our way，when it suddenly began to rain、
He had just left the room when it rained、 另外when还可表示原因“既然”。 It was foolish of you to take a taxi when you could easily walk there in five minutes、 ②while除引导时间状语从句外，还可引导让步或条件状语从句及作并列连词连结两个并列的简单句。如：While he was respected，he was not liked、 There will be life while there is water and air、 He is a worker while I am a doctor、 since引导从句时在主句是现在完成时的条件下，从句若为非延续性动词的一般过去时，表示从该动作的完成时刻算起，因此动词的语法形式与词义一致，是肯定意义；若从句动词为延续性动词的一般过去时，表示动作或状态从最后一次发生到现在。因此其含义与动词的词义恰好相反，具有否定意义，若从句延续性动词用现在完成时，则动词的语法形式与词义一致，是肯定意义。 I haven”t heard from her since she left Beijing、 自从她离开北京后，我从未收到她的信。 I haven”t written to her since she lived in London、 自从她离开伦敦以后，我从未给她写信。 Since I have been at this school we have three headmasters、
