如何学好英语语法:as...as形容词同级比较
从今天开始谈谈形容词比较级问题,第一天先看同级比较。

1
对于同级比较,一般常用“as+形容词原形+as”的结构,表达前后情况一致。

It is as tough and strong as any other cars running on the street.
它和街上跑的其它汽车一样牢固结实。

We would not be as strong as we could have been, and we could never fly.
那样我们将不能拥有我们应有的强壮,就永远不会飞翔。

2
还有一种情况是,as…as结构中形容词修饰单数名词,那么结构变成“as+形容词+a/an+名词+as”。

I do hope so because I want you to live as long and healthy
a life as I have.
我确实希望如此,因为我想要你像我一样活得健康长寿。

下面介绍几个由as…as组成的短语
As busy as a bee 忙如蜜蜂
As bright as day 亮如白昼
As cold as ice 寒冷如冰
As light as feather 轻如鸿毛
As loud as thunder 声如雷鸣
As firm as a rock 稳如磐石

形容词比较级的用法讲解

形容词比较级的用法讲解

形容词比较级的用法讲解形容词比较级的基本用法,即用于两个人或事物的比较,其结构形式如下:主语+谓语(系动词)+ 形容词比较级+than+ 对比成分。

也就是, 含有形容词比较级的主句+than+从句。

注意从句常常省去意义上和主句相My hair is as long as mine.在这两种结构中,第一个as是副词,而第二个as是连词;在第二个as的后面接名词、句子或代词的主格(一般不要接代词的宾格)。

例如:His bedroom is not as big as his sister's.It is not so hot as yesterday.2、在比较级 + than的结构前可以加上某些副词类的词,以对其进行修饰,如:far(远),even(甚至),much(许多),still(更,have.你学习越努力,你的成绩就越好。

The more we get together, the happier we’ll be.朋友越多,我们就越高兴。

b. 比较级+ and + 比较级。

它表示的意义是"越来越(怎么样)",在这个结构中的两个 "比较级"则要求词性相同。

例如:Our country becomes more and more beautiful.Amy is the taller of the two girls.Of the two books, the one on the right is the better.6、比较级的形式表达最高级的意思。

在这种情况下,往往是将一个人或是一件事与其他所有的人或事相比较。

做这种句子时有一点要特别注意--别忘了常在比较状语中用any other , else类的字眼,以将比较主体排除在比较对象以外,因为自己不可以与自己相比较。

例如:He is taller than anyone else in our class.。

英语比较结构的具体用法

英语比较结构的具体用法

英语比较结构的具体用法之前小编与大家一起学习了形容词比较等级的构成方式,而形容词比较等级用于句子当中便形成了所谓的“比较结构”。

英语比较结构最主要的有三种:as...as结构,more...than结构以及the most...结构。

as...as结构意为“和...一样”,其用法主要如下:一、基本模式:as+形容词原级+as-分句1.主句主语与as-分句主语不同,比较项目相同,此时as-分句有所省略。

如:Jack is as clever as Tom.2.主句主语与as-分句主语相同,但比较项目不同,此时as-分句不可用省略句。

如:The girl is as brilliant as she is beautiful. (这个女孩既漂亮又聪明。

)3.主句主语与as-分句主语不同,比较项目也不同,此时as-分句不可用省略句。

如:Her uncle was as base and unworthy as her father had been upright and honorable.(她叔叔卑鄙龌龊,不像她父亲那样正直可敬。

)4.基本模式的否定形式:Jack is not as clever as Tom. 或 Jack is less clever than Tom.二、变体模式:1. as many/much+名词+as-分句:She has eaten as many apples as her sister.He took as much water as he needed.2. as+形容词原级+名词词组+as-分句:Lucy is as clever a girl as her sister.3. 变体模式的否定形式:He didn’t take as much water as he needed.需要注意的是,同一句话,采取基本模式和变体模式,它们的含义基本相同,但句子的侧重点有所不同。

as as的用法

as as的用法

其基本意思为“与…一样”,其中的第一个as为副词,其后通常接形容词或副词(用原级),第二个as可用作介词(后接名词或代词)或连词(后接从句)。

使用时应注意以下几点。

如:(1) 在否定句中,第一个as 也可换成so。

如:He doesn’t study as [so] hard as his brother. 他学习不如他弟弟努力。

(2) 在该结构的两个as之间通常接形容词或副词的原级,但若涉及数量或程度,可用“as much+不可数名词+as”和“as many+复数名词+as”。

如:You’ve made as many mistakes as I have. 你犯的错误和我犯的一样多。

I haven’t got as much money as I thought. 我不像原来想像的有那么多钱。

其间接形容词时,有时该形容词还可修饰另一名词,但这个名词应带有不定冠词(注意词序)。

如:She is as good a teacher as her mother. 她和她妈妈一样是位好老师。

也可说。

如:She is a teacher as good as her mother.但不说。

如:She is as a good teacher as her mother. / They are as good teachers as us.(3) 第二个as后接从句时,该as通常为连词,但有时这个as还充当其后从句的主语或宾语,此时该as实为关系代词。

如:I gave him as much as he could eat. 他能吃多少,我就给了他多少。

We’ve got food for as many people as want it. 我们的食物,无论多少人吃都够了。

(4) 该结构根据情况可用使用以下修饰语。

如:(not) nearly, almost, just, nothing like, exactly, not quite, half, one-ten, twice, three times, 30 per cent等,并且这些修饰语必须置于第一个as之前,而不能置于其后。

as…as的用法中间加什么

as…as的用法中间加什么

as…as的用法中间加什么
“as…as”是一种常用的英语比较结构,用于描述两个事物在某一方面的相似程度。

在这个结构中,第一个“as”后面通常跟形容词或副词的原级,而第二个“as”后面则跟比较的对象。

在“as…as”结构中,中间可以加入形容词或副词来描述比较的内容。

例如:
•She is as tall as her mother.(她和她母亲一样高。


•He runs as fast as his brother.(他跑得和他哥哥一样快。

)在这些例子中,“tall”和“fast”都是形容词,用来描述比较的内容。

此外,“as…as”结构还可以用于否定句,表示“不如……”。

这时,第一个“as”后面仍然跟形容词或副词的原级,而第二个“as”后面跟比较的对象,但整个句子需要用否定词来修饰。

例如:She is not as tall as her sister.(她没有她姐姐高。


He doesn’t run as fast as his friends.(他跑得不如他的朋友快。


在这些例子中,“not”和“doesn’t”都是否定词,用来表示比较的结果不如预期。

总之,“as…as”结构中间加的是形容词或副词的原级,用来描述比较的内容。

同时,根据句子的语境和需要,还可以在结构中加入否定词来表示比较的结果不如预期。

在使用ASAS时,我们重点关注比较级这一形式。

形容词的比较级用于比较两个事物之间的差异。

通常,我们可以根据不同数量、质量或大小对物体进行比较。

在构成比较级时,大多数单音节形容词直接在后面加上"-er"来表示,例如:"taller"、"faster"、"stronger"等。

而如果一个单音节形容词以字母“e”结尾,则只需添加“r”,例如:"nicer"。

然而,对于多音节和部分双音节形容词,我们需要在形容词前面加上"more"来构成比较级。

例如:"more beautiful"、"more interesting"、"more intelligent"等。

as…as的句型结构

as…as的句型结构

as…as的句型结构As…as句型结构是一种常见的比较句型,它使用了形容词或副词,用来比较两个或多个元素。

As…as结构包括两部分,其中一部分为它的基础,用来表达期望的对象,而另一部分则为它的参照,表达与之比较的对象。

最常用的 as…as构中,as中的形容词或副词是及物动词,必须有它的宾语,也就是说,它的宾语必须有具体的对象,这决定了 as…as子的特点,必须有它的参照,以及它的有效性:例1:He is as tall as his brother.这句话很容易明白,在 as…as句型架构中,as及物动词, tall 它的形容词, his brother它的宾语,而 tall是 as…as子的参照,表达的意思就是“他和他的哥哥一样高”。

as…as构也可以用来表达否定的意思,只需要在 as…as子当中加入不定冠词 a an,就可以转变为否定句:例2:He isn as tall as a basketball player.上面这句话表达的意思就是“他没有篮球运动员那么高”。

此外,as…as构还可以与动词一起用,表达不同的意思:例3:He runs as fast as his brother.在这句话中,runs动词,它的宾语是 his brother,它用来参照,表达的意思就是“他跑得和他的哥哥一样快”。

除了上面提到的三种最常用的 as…as构外,还有很多其他的as…as构,比如:例4:The girl is as beautiful as a fairy.在这句话中,beautiful形容词,a fairy它的宾语,表达的意思就是“这个女孩像仙女一样漂亮”。

例5:The weather is as hot as yesterday.这句话的意思是“今天的天气和昨天一样热”, hot副词,yesterday它的宾语,也是参照。

此外,as…as构也可以用来表达肯定的意思:例6:She is as talented as her sister.这句话表达的意思是“她和她的姐姐一样有才华”,talented形容词,her sister它的宾语。

比较结构中的特殊结构

比较结构中的特殊结构

比较结构中的特殊结构as….as…结构此比较结构是同级比较,第一个as是副词,修饰形容词或其他副词,第二个as是连词连接的是比较状语从句;前者连接的是“比较方面,后者连接的是比较对象”;意为“和…一样….”例:He is as old as I am.He used to be almost as well-off(富裕) as his brother was.not as /so …as…结构此结构是as…as…的否定形式,表示“不像…那样…”,强调后者(第二个as的后面对象)强于前者。

例:People are not so genuine as they used to be.The Chinese people are not so poor as many Americans imagine.not so much A as B结构从原理上说,此结构与“not as/so …as…”的意思一致,只不过多了much表示程度,所以意义更加具体,可理解为“与其….不如…”例:He is not so much a doctor as a teacher.It was not so much that I disliked her as that I just was not interested in the whole businessThe great use of a school education is not so much to teach you things as to teach you the art of learning.另外,此结构可以写成not…so much as…例:He is not so much a doctor as a teacher.=He is not a doctor so much as a teacher.The problem set for society is not the virtues of this group so much as its adequacy for its function.not so much as..结构这是一个加强否定语气的结构,可理解为一个固定搭配,意为“甚至没有…”例:I do not so much as his name.He has not so much as been to the capital of his country.We now pass through these electronic machines without so much as a glance.as much…as…结构原理上此结构和as…as…结构一致,只不过多了much(表程度),所以意义更加具体,可以理解为“和…(在同等程度上)一样”例:The gorilla remains as much as a mystery as they used to be.He is as much a question as anything else.此结构有时可改写成…as much as…as well as结构此结构表示“不仅…”或“和…”,此机构后面的事物只是比较对象,前面的才是要强调的重点。

形容词和副词的比较级和最高级用法和构成法

形容词和副词的比较级和最高级用法和构成法

形容词和副词的比较级和最高级用法和构成法I 形容词和副词的比较级和最高级的用法1)同级比较。

常用句型为:肯定结构:as+形容词(副词)原级+ as否定结构:not so (as)+形容词(副词)原级+as如:Our garden is as beautiful as theirs.Jane didn't write as/so carefully as her elder sister.上述本句型前可以有表示倍数或分数的修饰语,如:This room is three times as large as that one.2)程度不等的比较,常与than连用,其基本句型是:A+形容词(副词)比较级+ than B如:Shanghai is bigger than any other city in China. Which do you like better, strawberries or grapes?3)最高级。

最高级用于三者或三者以上的比较,其结构是:the+形容词(副词)最高级+比较范围(of/among/in短语)如:Spring is the best season in Shanghai. David is the cleverest among the three brothers. Tom jumps (the) farthest of all the students.注:副词的最高级前the可以省略。

II 学习比较等级时的—些注意事项1)比较的对象应当一致。

如:It's hotter in Guangzhou than Beijing.(误)It's hotter in Guangzhou than in Beijing.(正)A woman's heart beats faster than a man.(误)A woman's heart beats faster than a man’s.(正)2)不能与自身相比较。

as...as的用法

as...as的用法

as...as的用法“asas”的用法在英语学习中,“asas”这个结构是非常常见且重要的。

它的用法灵活多样,能够帮助我们准确、生动地表达各种程度和比较关系。

接下来,让我们详细了解一下“asas”的具体用法。

“asas”的基本结构是“as +形容词/副词原级+as”,表示“和一样”。

比如,“She is as beautiful as her sister”(她和她姐姐一样漂亮。

)在这个句子中,“as beautiful as”就是在比较两个人的美貌程度是相同的。

需要注意的是,在使用“asas”结构时,前后所接的形容词或副词一定要用原级,不能用比较级或最高级。

比如,我们不能说“She is as more beautiful as her sister”或者“She is as the most beautiful as her sister”,这两种表达都是错误的。

“asas”在句中可以充当不同的成分。

它可以作定语,比如“A man as wise as Solomon”(像所罗门一样聪明的人);也可以作状语,比如“He runs as fast as his brother”(他和他哥哥跑得一样快。

)当我们想要表达“不如”时,可以使用“not asas”或“not soas”,这两个结构的意思是相同的。

例如,“This book is not as interesting as that one”(这本书不如那本有趣。

)在实际运用中,“asas”还会有一些特殊的用法。

比如,“as much as”和“as many as”。

“as much as”通常用于不可数名词,“as many as”则用于可数名词复数。

例如,“He earns as much money as I do”(他挣的钱和我一样多。

)“There are as many students in our class as in theirs”(我们班的学生和他们班的一样多。

as as 倍数用法

as as 倍数用法

as as 倍数用法1. 概述“as as” 是英语中一种常用的比较结构,用于表示两个事物在某种程度上具有相似或相同的特征或程度。

它可以用来进行正面的比较,也可以用于负面的比较。

“as as” 结构通常由一个形容词或副词的原级形式加上“as” 来构成。

在句子中,第一个“as” 表示程度或数量,第二个“as” 表示比较对象。

2. 用法2.1 正面比较当我们想要比较两个事物在某种程度上相似或相同时,可以使用“as as” 结构来表达。

例如: - He is as tall as his brother.(他和他的兄弟一样高。

) - The cake is as delicious as the one I had yesterday.(这个蛋糕和我昨天吃的那个一样好吃。

)在上述例句中,第一个“as” 后面的形容词“tall” 和“delicious” 分别表示两个事物的特征,第二个“as” 表示比较对象。

2.2 负面比较除了正面比较外,“as as” 结构还可以用于负面比较,表示两个事物在某种程度上不相似或不同。

例如: - She is not as smart as her sister.(她不如她的姐姐聪明。

) - This restaurant is not as good as the one we went to last time.(这家餐厅不如我们上次去的那家好。

)在上述例句中,“not” 表示否定,强调了两个事物在某个方面的差异。

3. 注意事项3.1 形容词和副词的原级形式在使用“as as” 结构时,我们需要使用形容词或副词的原级形式。

如果形容词或副词是一个多音节词或以“-y” 结尾的词,则需要在词尾加上“as”。

例如: - This car is as expensive as that one.(这辆车和那辆车一样贵。

)- He runs as fast as his friends.(他跑得和他的朋友们一样快。

形容词的比较结构as的两种形式
一、基本模式:as+形容词原级+as-分句
1、主句主语与as-分句主语不同,比较项目相同,此时as-分句有所省略。

如:
Jack is as clever as Tom。

2、主句主语与as-分句主语相同,但比较项目不同,此时as-分句不可用省略句。

如:
The girl is as brilliant as she is beautiful。

Her uncle was as base and unworthy as her father had been upright and honorable。

(她叔叔卑鄙龌龊,不像她父亲那样正直可敬。


4、基本模式的否定形式:
Jack is not as clever as Tom。

或Jack is less clever than Tom。

二、变体模式:
1、as many/much+名词+as-分句:
She has eaten as many apples as her sister。

He took as much water as he needed。

2、as+形容词原级+名词词组+as-分句:
Lucy is as clever a girl as her sister。

3、变体模式的否定形式:
He didn’t take as much water as he needed。

需要注意的是,同一句话,采取基本模式和变体模式,它们的含义基本相同,但句子的侧重点有所不同。

例如:
基本模式:I haven’t seen a car as old as this for years。

(重点在名词car)
变体模式:I haven’t seen as old a car as this for years。
