英语比较状语从句的用法大全
比较状语从句
比较状语从句主要用来表达人或事物的属性或特征的不同程度。所以，比较关系都是有关形容词和副词的比较用法的。
比较状语从句分为三类：同级比较、比较级和最高级。
(一)同级比较
当要表达不同的人或物在某方面是一样的时，一般采用同级比较，其基本结构为：as...as...。
其中，第一个as为副词，所以后面接的是形容词或副词;而第二个as为连词，所以后面接的是主谓结构，而且谓语动词因为跟主句的一般都是一样的，所以往往会省略掉。如：
The soldier is as brave as a lion. (这个战士象狮子一样勇猛。)
The short-distance runner wish he can run as fast as the ostrich. (这位短跑运动员真希望自己能跑得像驼鸟一样快。)
【注意】
1、as...as...的否定结构为：not so/as...as...。其中，第一个as也可以换作so。如：
The soldier is not so/as brave as a lion.
The short-distance runner cannot run so/as fast as the ostrich.
2、the same as也表示“与...一样”。如：
Twins look the same as each other. (双胞胎看上去长得一样。)
The imperial gallon is not the same as the US gallon. (英制的加仑和与美制的容量不同。)
3、just as表示“正如”，也有“just as..., so...”的句型用法。如：
It has turned out just as I wished. (它终于如我所愿。)
Just as you would not, so neither would they. (正如你们不愿意一样，他们也不会答应的。)
4、in the same way that表示“正如，与...一样”。如：
The brain works like an electrical circuit, sending impulses along nerve fibres in the same way that current is sent through wires. (大脑的工作有如电路的电流通过导线输出，它的脉冲是沿神经纤维发出。)

(二)比较级
比较级用来表示某人或某物比其他人或物更加如何，其基本结构为：more...than...。如：
He is a head taller than his younger sister. (他比他妹妹高一头。)
Nothing in the world moves faster than light. (世界上再没有比光运动得更快的东西了。)
【注意】
1、形容词或副词的比较级变化规则
1)直接+er。如：taller/faster
2)以不发音的e结尾+r。如：nicer/later
3)以辅音+y结尾的，改y为i+er。如：drier/slier(狡猾的)
4)以重读闭音节结尾的，双写最后一个辅音字母+er。如：hotter/slimmer
5)三音节及以上的单词，用more来引导比较级。如：more beautiful/more expensive
6)派生词即使是两个音节，也要用more来引导比较级。如：more slowly/more friendly
7)不规则变化。如：good-better, bad-worse, far-farther/further, old-older/elder
2、有时，比较级中的than会省略，因为比较的对象暗含在上下文中，没必要指出。如：
He thought to himself that he could get richer by making them work harder. (他心中盘算着，如果叫他们更卖力地干，他就可以发更大的财。)
I wish this book was written in bigger character. (我希望这本书的字再大一点儿。)
3、more than表示“不仅仅，不止是”。如：
Brains are more than just education. (有头脑不仅指受过教育。)
She is more than a match for me. (她比我更优秀。)
4、no less...than与no more...than，表示“与...一样的...”。如：
外教一对一https://www.doczj.com/doc/796474831.html, He is no less clever than his elder brother. (他和他的大哥一样聪明。)
She is no less good at swimming than Mary. (她和玛丽一样擅长游泳。)
He is no more considerate of others than his brother is. (他不体谅别人，就跟他弟弟一样。)
A whale is no more a fish than the seal is. (正如海豹不是鱼那样,鲸也不是鱼。)
5、the more..., the more...句型，表示“越...，越...”。如：
The more he has, the more he wants. (他得到越多，想要的也越多。)
The more you soften a request, the more polite it becomes. (你愈使请求柔婉，请求就愈变为客气。)
这种句型的句子如果意思明显，经常省略主句的主语和谓语，有时主、从句的主语和谓语都可以省略。如：
The more, the better. (越多越好。)
The higher the temperature, the greater the pressure. (温度越高，压力越大。)
6、a bit、a little、rather、much、far、by far、many、a lot、a great deal、any、still、even等可以用来修饰比较级。如：
The results are even better than we had expected. (这六年来发生的变化，确实比预料的要好。)
A bicycle's often far more convenient than a car in busy cities. (在热闹的都市里骑自行车往往比坐汽车方便得多。)
(三)最高级
当三者或三者以上的人或物进行比较时，用最高级。形容词的最高级前面要加定冠词the，副词最高级前面的the可以省略。在含有最高级的句子中，常有一个in/of短语来表示比较范围。如：
My aunt lived through the worst years of the depression. (我姑妈经历了大萧条时期最糟的年头。)
Let's see who can get there quickest. (咱们看看谁最先到达。)
【注意】
1、形容词和副词最高级的变化规则
其变化规则与比较级类似，不同的是，最高级的词尾是加-est或-st，且最高级前往往要加定冠词。具体规则请参考第(二)项中有关比较级的内容。
2、比较级的否定结构可以表达最高级。如：
外教一对一https://www.doczj.com/doc/796474831.html, I can't agree more. (我完全赞同。)
We can't have a worse day. (今天真是糟糕透顶!)
3、名词或代词主语+be+the+最高级+名词+that+sb.+have ever done。如：
Jim is the bravest soldier that we have ever seen. (吉姆是我们见过的最勇敢的士兵。)
It is the best film that she has ever watched. (这是她看过的最精彩的电影。)
【注意】
句中的连接词that因为在从句中是作宾语的，所以经常可以省略。
英语让步状语从句用法总结（一） 让步状语从句的用法一（表示“虽然，即使，尽管”） 1. although，though，even though，even if都表示“虽然，即使，尽管”之意，though 和although 语气较弱(其中的though 比although 通俗, 不如although 正式)，even if和even though 带有强调意味而显得语气更强。例如：Although they are poor, they are happy. 虽然他们很穷，但很快乐。天气虽然很冷, 但他没有穿大衣就出去了。即使他们可能不会成功，但他们仍努力尝试。那篇文章虽然很短，但很重要。他好一点了，虽仍未痊愈。即使下雨，她也是走着去工作的。今晚我将去拜访他，即使我只能停留一小会儿。 注意：though 引导的让步状语从句的用法比较特殊，它可以倒装，也可以不倒装，具体用法参见as引导让步状语从句的用法。 2. as引导让步状语从句表示“虽然、即使、尽管”，其引导的让步状语从句必须采用倒装结构，as引导的倒装形式的让步状语从句的基本结构为：形容词/副词/名词(单数可数名词前一般不带冠词，有时也可见单数可数名词前形容词与不定冠词连用、形容词放在不定冠词前)/动词/过去分词＋as＋主语＋谓语的其他部分。注意体会下列典型例句：Great as the author was, he proved a bad model. 这位作者尽管了不起，到头来却成了一个坏榜样。这个故事看似荒唐，却是真的。虽然他很富有，但他并不幸福。倒装时要省去单个名词前的冠词)尽管还是个孩子，他却能分辨黑白。他尽管勇敢，可见到蛇还是发抖。尽管伤势很重，他仍然十分乐观。虽然尽了最大努力，但是他仍然不能搬动那块石头。 ［考题1］We had to wait half an hour ____ we had already booked a table. A. since B. although C. until D. before ［答案］B ［解析］下划线处之后所述的“我们已经预订了一桌”与前面所述的“我们已经不得不等了半个小时”之间语意相反，四个选项中although表示“即便……”，引导让步状语从句最为合适。 ［考题2］____ most of the earth’s surface is covered by water, fresh water is very rare and precious. A. As B. Once C. If D. Although ［答案］D ［解析］句意为：虽然地球表面覆盖着水，但是纯净水仍然很稀有、珍贵。下划线处应引导让步状语从句，填入although最为合适。 ［考题3］____ he has limited technical knowledge, the old worker has a lot of experience. A. Since B.

初中英语定语从句的用法解析 【摘要】定语从句是一种形容词的关系从句。它由关系代词或关系副词引导（1）。初中英语中的定语从句仅限于限制性定于从句，但对初中生来说，定语从句既是一个重点，也是一个难点。 【关键词】定语从句先行词关系代词关系副词 一、英语中的定语从句与汉语中的定语位置不同。 在复合句中，修饰某一名词或代词的从句叫做定语从句。英语中的定语从句始终要放在被修饰的词之后，而汉语中的定语则放在被修饰词之前。如： The man who / that I saw at the school gate yesterday is my English teacher. 先行词定语从句 昨天我在校门口看见的那个人是我的英语老师。 二、英语从句中的句型结构比较复杂，有先行词、关系代词或关系副词。被定语从句修饰的词叫先行词，引导定语从句的关联词有关系代词或关系副词。限制性关系分句和它的先行项的所指意义有着不可分割的联系（2）。关系代词或关系副词放在先行词和定语从句之间起纽带作用，关系代词或关系副词在定语从句中要充当一个成分。关系代词在句中可作主语、宾语或定语，关系副词在句中作状语。如： I am waiting for the boy who /that is wearing a red coat. （主语） 先行词关系代词 我正在等穿着红色外套的那个男孩。 The dictionary that / which my sister gave me last Sunday is very expensive.(宾语) 先行词关系代词 我姐姐上周星期天给我的那本字典很贵。 The woman is his mother whose name is Linda Brown. (定语) 先行词关系代词 那个是他的母亲，名叫琳达·布朗。 That is the house where my father used to live.(状语) 先行词关系副词 那是我父亲曾经居住过的房子。 三、初中英语中的定语从句关系代词或关系副词的具体用法。 1. who指人（也可用that），在定语从句中作主语，也可作宾语。如： Yesterday I helped an old man who / that lost his way. （主语） 昨天我帮助了一位迷路的老人。 Mr Wang is the man (who / that / whom )you met in the zoo this morning.(宾语) 王先生就是今天早上你在动物里遇到的那个人。 注意：关系代词who指人,作宾语时，可用whom代替；作宾语时，关系代词可省略。作其它成分，关系代词则不能省略。 2. whose指人，也可指物。在定语从句中作定语。 The boy whose mother is ill is staying at home to look after her today. 其母亲生病的那个男孩今天呆在家里照顾她。 I have a story book whose cover is red. 我有一本封面是红色的故事书。 3. which指物（也可用that），在定语从句中作主语，也可作宾语。如： Football is a game which / that is liked by most boys. （主语） 足球是被大多数男孩喜欢的运动。 I don’t believe the news which / that Tom won the game. (宾语)
高考英语状语从句八类常考考点 状语从句是高考英语的必考考点，综观近年来各省市状语从句的考题情况，我们发现以下八类状语从句特别值得关注： 一、in case引导的状语从句 根据语境的不同，in case既可表示“如果”“万一”，引导条件状语从句；也可表示“以防(万 一)”，引导目的状语从句。下面两道真题均选in case： 1. Leave your key with a neighbor ______ you lock yourself out one day. (北京卷) A. ever since B. even if C. soon after D. in case 2. My parents live in a small village. They always keep candles in the house ______ there is a power cut. (重庆卷) A. if B. unless C. in case D. so that 【解析】两道题都选in case，均表示“以防万一”。 二、before引导的状语从句 尤其要注意“it+be+一段时间+before…”这一句型。如： 1. The field research will take Joan and Paul about five months; it will be a long time ______ we meet them again. (安徽卷) A. after B. before C. since D. when 2. He was told that it would be at least three more months ______ he could recover and return to work. (江西卷) A. when B. before C. since D. that 【解析】两道题均before。第1题涉及的句式为：It will be a long time before…，意思是“要过很久才会……”；第2题涉及的句式为：it was some time before…，意思是“在……之前过了一段时间”，通常可转译为“要过一段时间才会……”。 三、while引导的状语从句 尤其要注意while表示“尽管”“虽然”时的用法（此时它引导的不是时间状语从句，而是让步状语从句——此用法许多同学并不熟悉，值得特别注意！）。如： ______ I really don’t like art, I find his work impressive. (山东卷) A. As B. Since C. If D. While 【解析】答案选D。while在此表示“尽管”“虽然”，又如：While the work was difficult, it was interesting. 尽管工作有难度，但很有趣。/ While I understand what you say, I can’t agree with you. 虽然我理解你的意思，但我还是不同意。 另外，while表示对比的用法也值得注意（此时它表示“而”）。如： The cost of living in Glasgow is among the lowest in Britain, ______ the quality of life is probably one of the highest. (天津卷) A. since B. when C. as D. while
冠词 一．不定冠词 1.不定冠词a,an A用于以辅音因素或半元音因素/j/,/w/开头的单词。 An用于元音因素开头的单词 注意:元音因素开头的单词，首字母不一定就是元音字母例如，hour,honest等单词，看起来是以辅音字母开头，但是发音时辅音字母h没有发音，而是以元音开头，因此前面应加不定冠词an。而有些单词如university,uniform等单词，是以元音字母u开头，但是读音时u 发半元音/j/开头，所以前面应加a。 2.不定冠词的用法。 （1）用于可数名词的单数前，表示数量“一”，如： I have a new pen. (2)表示一类人或物，如： An elephant is big and strong. (3)第一次提到的人或物，如： Look, a dog is running to us. (4)表示“每一”的意思，如： I go shopping once a week.
3.不定冠词的固定搭配 have a look 看一下have a good time 玩得愉快 take a break 休息一下take a walk 散步 in a hurry 急匆匆地half an hour 半小时 a lot of 许多，大量 a great deal of 大量+不可数名词a number of 许多+可数名词 a few 一些+可数名词 a little 一些+不可数名词 二．定冠词 1.定冠词the的用法 （1）特指某些人或物，例如： The woman in red dress is my mother. (2)特指前面提到过的人或物，例如： I have a dog. The dog is cute. (3)指谈话双方都知道的人或事物。 What do you think of the novel? (4)指宇宙间独一无二的东西，如： The moon is bright at night. (5)用于单数名词前表示一类人或物，如： The horse is a useful animal. (6)用于序数词前，如：、
高中英语定语从句用法全面系统讲解（1） 一、概述 在复合句中，修饰某一名词或代词，用作定语的从句叫做定语从句(attributive clause)。被定语从句所修饰的词叫做先行词(antecedent)。定语从句必须放在先行词之后。引导定语从句的关联词有关系代词who、whom、whose、which、that和关系副词when、where、why 等。 Finally, the thief handed everything that he had stolen to the police. 最后，那个小偷向警察交出他偷的所有的东西。（引导词是关系代词that） His parents wouldn't let him marry anyone whose family was poor. 他父母不让他和家庭困难的人结婚。（引导词是关系代词whose） In the dark street, there wasn't a single person to whom she could turn for help. 在那个黑暗的街道上，没有她可以求助的人。（引导词是关系代词whom） In 1519 another traveller who went to America from Europe discovered the tomato. 1519年另一位从欧洲去美洲的旅行家发现了西红柿。（引导词是关系代词who） I still remember the day when I first came to Beijing. 我仍然记得第一次去北京的那一天。（引导词是关系副词when） This is the house where we lived last year. 这就是我们去年住的房子。（引导词是关系副词where） 二、关系代词和关系副词的功用能 关系代词和关系副词用来引导定语从句，在先行词和定语从句之间起纽带作用，使二者联系起来。关系代词和关系副词可作定语从句的一个成分。关系代词可作主语、宾语、定语；关系副词可作状语。 1、作主语 关系代词在定语从句中作主语时，从句的谓语动词的人称和数应与先行词一致。 All that is needed is a supply of oil. 所需要的是大量的油。（引导词that在句中作主语） A plane is a machine that can fly. 飞机是会飞的机器。（引导词that在句中作主语） The foreigner who visited our class yesterday is from Canada. 昨天到我班来访的外国人来自加拿大。（引导词who在句中作主语） They planted the trees which didn't need much water. 他们种植了需水不多的树木。（引导词which在句中作主语） 2、作宾语 在定语从句里作宾语的关系代词在口语中常被省去 The noodles (that) I cooked were delicious. 我煮的面条美味可口。（引导词that，可省略）

英语中六大从句用法总结 从句是指用于复合句中担当某个句子成分的主谓结构。虽说从句自身的句子结构是完整的，但是它不能视为独立的句子，因为它离开了主语就无法独立、完整地表达意思。按其所能表达的意义而言,它相当于一个词或是一个词组. 按从句的句子功能划分（也就是按从句在句子中所担任的成分来划分），从句可分为：主语从句、宾语从句、表语从句、同位语从句、定语从句和状语从句。 1.主语从句 1）主语从句可直接位于主语的位置，如果从句较长，谓语又较短，可用it作形式主语，而将从句放在句末。常见的句型有： *It is a fact\a pity\a question\good news that... *It seems\appears\happened\has turned out that... *It is clear\important\likely\possible that... *It is said\reported\estimated\has been proved that... It is said that comic books create a connection between people of the same generation. It seems that the performance is very useful. 2)what引导的主语从句表示“...的东西时”，一般不用it作形式主语。 What we lack is experience. 3)what,who,when,why,whether等词含有各自的疑问意义，但它们引导的主语从句，都用陈述语序。 How the plan is to be carried out should be discussed again. I did know why I felt like crying. 2.宾语从句 1）宾语从句可位于及物动词、介词和某些形容词后。连词that常可省略。介词后一般接疑问词引导的宾语从句。in that(因为),except that(除了),but that(只是）已构成固定搭配，其他介词后一般不接that引导的宾语从句。 *I promised that I would change the situation. *All this is different from what American young people would say about friendship. *He is certain that watching so much television is not good for children. *This article is well-written except that it is a bit too long. 2)宾语从句后如有宾补，要用形式宾语it来代替，而把宾语从句移至宾补之后。 He has made it clear that he would not change his mind. 3)在think,believe,suppose,expect等动词后的宾语从句中，如果谓语是否定的，一般将否定词移至主句谓语上，宾语从句则变成肯定形式。 He didn't think that the money was well spent. 3.表语从句 表语从句出现在结构为“主语+系动词+表语从句”的句子中。表语从句除可用that,what,when,why,whether,how等引导外，还可由because,as if(though)等引导。that常可省略。如主句主语为reason,只能用that引导表语从句，不可用because.
冠词的用法 一：冠词的定义 冠词是置于名词之前，对名词起限制作用的一种虚词。 冠词可以说是名词的一种标志，它不能离开名词而独立存在。 二：冠词的种类 1. 定冠词: the 2. 不定冠词: a / an 当紧跟不定冠词之后的单词是辅音发音开头时,不定冠词应该用a, 当紧跟不定冠词之后的单词是元音发音开头时,不定冠词应该用an.。 a + [辅音……] a wallet, a European country an + [元音…… ] an hour, an 8-year-old boy 三：冠词的位置 冠词一般要放到名词或名词短语（形容词+名词、副词+形容词+名词、或其它修饰语+名词）的前面。如：the last few days.最近几天 a very lovely girl 但是以下情况例外： 1）all/both/half/+the+(形容词)+名词 如：all the new cars all the friends half the books 2)what/such/many+a/an+(形容词+)单数可数名词 如：what a nice day many a time such a bad boy 3)rather/quite/half +a/an+单数可数名词 注意：这种情况下，a/an也可以放在rather/quite等前面 如：quite a long time/a quite long time rather a busy day/a rather busy day 4)exactly/just+a/an+(形容词)+名词 如：Just a moment,please. 5)as/how/so/too/however+形容词+a/an+单数可数名词 如：It was as pleasant a day as I have ever spent. 这是我度过的最愉快的一天。 She is so beautiful a girl. It is too difficult a book. 注意:在以下六种词中,只能使用其中的一种词修饰名词: 1）冠词、2）指示代词(如:this, that, these, those)、3）形容词性物主代词(如:my, your, his, her等)、4）名词所有格(如:Tom’s, the Smiths)、5）不定代词(如:every, each, any)以及6）疑问代词(如:which, what). 如： 1. 我的一位朋友(不能说: my a friend) a friend of mine 或one of my friends 2.你的这两位老师(不能说:your the two teachers) the two teachers of yours 3.哪一把伞是你的(不能说:Which an umbrella is yours) Which umbrella is yours 4. 一辆这种自行车(不能说:a this kind of bike) a bike of this kind 5.每隔几天一次(不能说:once every a few days) once every few days 四：冠词的用法 学冠词的用法必须明确两个概念： 1）泛指：一类中的任何一个个体，不明确，未指明哪一个。 2）特指：说话者和听话者都知道所指的内容。 冠词用法的总原则： 名词前用不用冠词，用哪一类冠词，通常取决于三方面因素：
定语从句的用法 一、定语从句的概念 在复合句中,修饰某一名词或代词的从句叫定语从句。被修饰的名词或代词叫先行词,定语从句一般放在先行词的后面。(尤其是限制性定语从句) （定语在汉语中常用……的表示。它主要由形容词担任，此外，名词，代词，数词，分词，副词，不定式以及介词短语也可 以来担任，也可以有一个句子来担任。单词做定语是通常放在它所修饰的词之前，作前置定语。短语和从句做定语是则放在所 修饰的词之后，做后置定语。） 二、定语从句的关系词 引导定语从句的关系词有关系代词和关系副词,常见的关系代词包括that, which, who(宾格whom,所有格whose)等,关系副词包括where, when, why等。关系代词和关系副词放在先行词及定 语从句之间起连接作用,同时又作定语从句的重要成分。 三、定语从句的分类 根据定语从句与先行词的关系,定语从句可分为限制性定语从句及非限制性定语从句。 1. 限制性定语从句紧跟先行词,主句与从句不用逗号分开,从句不可省去 2.非限制性定语从句主句与从句之间有逗号分开,起补充说明作用,如省去,意思仍完整。 四、关系代词的用法 1. that 既可以用于指人,也可以用于指物。 Mary likes music that is quiet and gentle.玛丽喜欢轻柔的音乐。(that作主语) The coat (that) I put on the desk is blue.我放在桌子上的那件外套是蓝色的。(that作宾语) 2.which用于指物 The building which stands near the train station is a supermarket.位于火车站附近的那座大楼 是一家超市。(作主语) The film (which) we saw last night was wonderful. 我们昨天晚上看的那部电影很好看。(作宾语) 3.who, whom用于指人 The girl who often helps me with my English is from England.经常在英语方面帮助我的那个女 孩是英国人。(作主语) Who is the teacher (whom) Li Ming is talking to? 正在与李明谈话的老师是谁?(作宾语) 注意：whom 在口语和非正式语体中常用who代替，可省略。 4 whose用于指人，也可以用于指物（相当于of which 注明:whose=the+物/人+of which/whom ） Do you like the book whose color is yellow? Do you like the book the color of which is yellow? I once lived in the house whose roof has fallen in . I once lived in the house ,the roof of which has fallen in . 5.关系词的区别 （1）关系词只能用that的情况: a. 先行词被序数词或形容词最高级所修饰,或本身是序数词、基数词、形容词最高级时
