1）He is not more diligent than you are.他不象你那样勤奋。（重点在 you are diligent 。他也勤奋，但不如你勤奋。）
2)I'll stay here not more than three days. 我将待在这里最多不超过三天。
ⅡAs well as
作为习语用作介词时，as well as的涵义是“还有”、“不但…而且…”。值得注意的是，在A as well as B的结构里，语意的重点在 A，不在 B。因此，“He can speak Spanish as well as English．”的译文应该是：“他不但会说英语，而且会讲西班牙语”，决不能译作：“他不但会说西班牙语，而且会讲英语”。如果这样翻译，就是本末倒置了。as well as和not only… but also…同义，但前者的语意重点和后者的语意重点恰好颠倒。
如果 as well as用作连词引出比较从句，其义为“和…一样好”。因此，“He speaks Spanish as well as English．”应译作：“他说西班牙语像说英语一样好”。语意的重点依旧在前部，不在后半部。
请注意 as well as以下的用法：
She called on you as well as I．
不但我来看你，她也拜访了你。
She called on you as well as me．
她不但拜访了我，也拜访了你。
在下列句中，as well as表示“像…一样”的涵义：
She as well as you is an English teacher．
她像你一样也是英文教师。
这里的谓语动词用is，不用are，因为句中的主语是she，不是she和you。
As well是副词短语，其义为“也”，相当于too，它一般放在句末，有时和连词and或but搭配使用。例：
He is a worker，and a poet as well．
他是工人，但也是诗人。
China possesses enormous quantities of coal and is rich in other minerals as well．
中国拥有大量煤炭，其他的矿藏也很丰富。
Mr．Liu can speak English，but he can speak Cantonese as well．
刘先生会说英语，但他也能讲广东话。
Ⅲ英语倍数表达法
用英语表达"A 是 B 的 N 倍长（宽，高，大，重等）"，"A 比 B 长（宽，高，大，重等）N 倍" 或"A 的长度（宽度，高度，大
小，重量等）是 B 的 N 倍"，可用下列几种句型。
1."A + be + 倍数 + as + 计量形容词原级 + as + B".
This tree is three times as tall as that one. 这棵树是那棵树的三倍高。
His father is twice as old as he. 他父亲的年纪有他两倍大。
2."A + be + 倍数 + 计量形容词比较级 + than + B "
The Yangtze River is almost twice longer than the Pearl River.
长江差不多比珠江长两倍。
The dictionary is exactly five times more expensive than that one.
这本字典比那本恰好贵5倍。
3."A + be + 倍数 + the + 计量名词 + of + B "
The newly broadened square is four times the size of the previous one.
新扩建的广场是未扩建时的四倍大。
4."The + 计量名词 + of + A + be + 倍数 + that + of + B "
The size of the newly broadened square is four times that of the previous one. 新扩建的广场为以前的四倍大。
5.其它
I'm twice/ double his age. 我的年龄是他的两倍。
I've paid five times the usual price for the stamp.
我出了5倍于往常的价格买这枚邮票。

收入增加了50%.
The price of TVs are twofold( adj. 两部分的, 双重的) down over these years. 近几年来，电视机的价格下降了两倍。
Ⅳas/so…as用于原级的比较，但在实际应用中，此结构在不同的语境中含义差异较大。现把其用法整理归纳如下，以供读者参考。
1、as/so…as结构的基本模式是：as+形容词/副词+as从句
a.表示不同人或物同一性质的比较，意为“…和…一样…”。
The tree is as tall as the building(is).这棵树和那栋楼一样高。
John is as bright as Bob(is).约翰和鲍勃一样聪明。
上述两例句的否定形式就分别可改为：（so通常用于否定句中）The tree is not as/so tall as the building.
John is not as/so bright as Bob(is).
b.表示同一个人或物不同性质的比较，意为“既…又…”
She works as happily as(she)plays(happily).她愉快地工作，尽情地玩。
The girl was as brilliant as she was beautiful.这个女孩既漂亮又聪明。
He's not so wise as he is witty.他为人风趣，但欠明智。
The problems are as numerous as(they are)trivial.问题又多又繁琐。
c.用于表示两个人或物不同性质的比较，表示程度相同或相当，意为“…而…”。
He was as handsome as his wife was beautiful.
他长得非常英俊，他的妻子也长得非常漂亮。
His uncle was as base and unworthy as his father had been upright and honorable.
他叔叔卑鄙龌龊，不像他父亲那样为人正直。
He was as experienced as his brother was green.
他经验丰富，而他兄弟却涉世未深。
2、as/so…as结构的另一种模式是：as/so much/many+名词+as从句
She has written as/so many essays as her brother.(many+可数名词复数).
她写的文章篇数和她弟弟一样多。
It is as much your fault as your wife's. 这既是你的过错，也是你妻子的过错。（much+不可数名词）
He is as much a hypocrite as John. 他跟约翰一样是个伪君子。
另外half, nearly等词常和as/so…as连用，但just, twice/nine times等则只与as…as连用。
He sold nearly as/so many videos as I did.
他售出的录像带几乎和我售出的一样多。
You've made just as many mistakes as I have. 我和你犯的错误一样多。
We've produced twice as much cotton this year as we did last year. 我们今年的棉花产量是去年的两倍。（倍数+as+much+不可数名词+as从句）
The total oil output in the west is 80%as much as that in the east. 西部地区的石油总产量是东部地区的百分之八十。
3、as…as结构的另一变体形式是：as+形容词原级+名词词组
+as
I don't want as expensive a car as this.=I don't want a car as expensive as this.
我不要这么贵的汽车。
Notes:
a.当as…as与表示重量、数量、时间、距离、价格等的计量名词连用时，往往并不表示比较，而是构成一个形容词组，意为“重达…，多达…，高达…”等。
The river is as deep as10 meters.这条河深达10米。
Frosts often occur as late as May. 往往到5份还有霜。
b.as/so…as…结构也可表示让步
As(so)bad as he is ,he has his good points.他虽不好，但也有其优点。
c.as+原级+as any(或ever);as+原级+as…can be; nothing(或no)+so+原级+as…等结构表达的是最高级意义，即在某种程度上或某方面达到极限或最大限度。
She is as bright as any in the school.她是学校里最聪明的学生。
He is as great as a mathematician as any.他是一位非常杰出的数学家。
He is as happy as happy can be.他幸福无比。
No one is so deaf as those who won't listen.最聋者莫过于不听劝说的人。
形容词的比较级和最高级知识讲解及练习 ----昂立外语 绝大多数形容词有三种形式:原级、比较级、最高级三种形式 Ⅰ. 常见的形容词及比较级和最高级的构成 （1）规则变化： ①一般情况下在词尾加-er、est Eg: calm---calmer calmest tall---taller tallest smart---smarter smartest ②以字母e结尾的直接在词尾加-er\est Eg: nice---nicer nicest fine---finer finest large---larger largest ③以“辅音+y 结尾的词，变y为i，再加-er\est Eg: early---earlier earliest happy---happier happiest busy---busier busiest ④一个元音字母加一个辅音字母结尾的单词，双写最后一个辅音字母，再加-er\est Eg: big---bigger biggest thin---thinner thinnest hot---hotter hottest ⑤多音节或部分双音节的形容词在原级前面加more Eg: popular---more popular most popular important---more important most imporant （2）特殊变化：
Ⅱ. 形容词比较级的用法：表示两者（人或物）的比较。 ⒈表达“A大于B”用 A … 比较级+than B ①. Tom比我胖。Tom is _____ (fat) than me. ②. 他的头发比我的短。His hair is ________(short) than _________. He has ________ (short) hair than ________. (注意比较对象的一致性) ③. 英语比语文重要。English is _______________ (important) than Chinese. ④. 我来的比你晚。I come _______ (late) than you.（副词的比较级） ⒉表达“A和B一样”，用 A … as 原级as B ①他和我一样高。He is as ________ (tall) as I/me. ②英语比语文重要。English is as _______________ (important) as Chinese. ③他的头发和我的头发一样长。His hair is ________ ________ _______ mine. ④他学习和你一样努力。He works _______ hard ______ you. ⒊表达“A不如B”，用A …not+as/so+原级+as+B。 ①这辆车不像那辆车一样贵 This car ______ _______ _______（expensive）that one. =This car is ______ _______ / than that one. =That car is ______ _______ than this one.
英语语法---比较级和最高级的用法 在英语中通常用下列方式表示的词： 在形容词或副词前加more(如more natural,more clearly )或加后缀-er(newer,sooner )。 典型的是指形容词或副词所表示的质、量或关系的增加。英语句子中，将比较两个主体的方法叫做“比较句型”。其中，像“A比B更……”的表达方式称为比较级；而“A最……”的表达方式则称为最高级。组成句子的方式是将形容词或副词变化成比较级或最高级的形态。 一、形容词、副词的比较级和最高级的构成规则 1．一般单音节词和少数以-er，-ow结尾的双音节词，比较级在后面加-er，最高级在后面加-est； （1）单音节词 如：small→smaller→smallest short→shorter→shortest tall→taller→tallest great→greater→greatest （2）双音节词 如：clever→cleverer→cleverest narrow→narrower→narrowest 2．以不发音e结尾的单音节词，比较在原级后加-r，最高级在原级后加-st； 如：large→larger→largest nice→nicer→nicest able→abler→ablest 3．在重读闭音节（即：辅音＋元音＋辅音）中，先双写末尾的辅音字母，比较级加-er，最高级加-est； 如：big→bigger→biggest hot→hotter→hottest fat→fatter→fattest 4．以“辅音字母＋y”结尾的双音节词，把y改为i，比较级加-er，最高级加-est； 如：easy→easier→easiest heavy→heavier→heaviest busy→busier→busiest happy→happier→happiest 5．其他双音节词和多音节词，比较级在前面加more，最高级在前面加most； 如：beautiful→more beautiful→most beautiful different→more different→most different easily→more easily→most easily 注意：（1）形容词最高级前通常必须用定冠词the，副词最高级前可不用。 例句：The Sahara is the biggest desert in the world. （2）形容词most前面没有the，不表示最高级的含义，只表示"非常"。 It is a most important problem.=It is a very important problem. 6．有少数形容词、副词的比较级和最高级是不规则的，必须熟记。 如：good→better→best well→better→best bad→worse→worst ill→worse→worst old→older/elder→oldest/eldest many/much→more→most little→less→least far →further/farther→ furthest/farthest 二、形容词、副词的比较级和最高级的用法 1．“A + be +形容词比较级+ than + B” 意思为“A比B更……”。 如：This tree is taller than that one. 这棵树比那棵树高。 注意： ①在含有连词than的比较级中，前后的比较对象必须是同一范畴，即同类事物之间的比较。 ②在比较级前面使用much，表示程度程度“强得多”。 如：A watermelon is much bigger than an apple. ③very, quite一般只能修饰原级，不能修饰比较级。 2．“比较级+ and + 比较级”或“more and more +原级”表示“越来越……” 如：It becomes warmer and warmer when spring comes.
☆形容词的比较级☆ 当我们需要对事物作出比较时，需要用到比较级。 比较级的句子结构通常是： 什么 + 动词be (am , is , are ) + 形容词比较级 + than（比）+ 什么 ,如： I’m taller and heavier than you. （我比你更高和更重。） An elephant is bigger than a tiger.（一只大象比一只老虎更大。）形容词的比较级是在形容词的基础上变化而来的，它的变化规则是： ①一般的直接在词尾加er ，如 tall - taller , strong - stronger , ②以e结尾的，直接加r ，如 fine – finer , ③以辅音字母加y结尾的，先改y为i再加er，如funny - funnier ④双写最后的字母再加er，如big – bigger, thin – thinner , hot – hotter 除此之外，还有几个特殊的单词，它的比较级和最高级都是不规则的，如：many / much（原形）– more（比较级）– most（最高级） little / few（原形）– less （比较级）– least（最高级） good（原形）– better（比较级）– best（最高级） bad （原形）– worse（比较级）– worst（最高级） far （原形）– further– furthest 附加：形容词的最高级变化类似于比较级，只是把词尾的er改成est，如： tall （原形）- taller （比较级）- tallest （最高级） long（原形）- longer（比较级）- longest（最高级） big （原形）- bigger（比较级）- biggest（最高级） ☆注意☆比较的两者应该是互相对应的可比较的东西。
英语中的比较级
比较句型 As /so ... as ... 结构︰as／so＋形容词或副词原级＋as… 说明︰此句型意为“…和…一样…”。比较两件东西，并表示它们的程度一样。第一个as 为<副词>，第二个 as 则为<副词><连接词>，引导<副词子句>，修饰第一个 as。在as…as 中可插入单数<可数名词>，即：“as＋<形容词>＋a／an＋<名词>＋as”。若是复数<名词>，可用“as many／few＋复数 <名词>＋as”；若是<不可数名词>，则用“as much／little＋<不可数名词>＋as”。“as＋原级（形、副）＋as＋原级（形、副）”这形式表示有关同一人（物）的两种不同的性质、状态是一样程度的，译作“既有…且还有…”。 he is as handsome as his brother (is). 他和他哥哥一样英俊。 judy goes to the movies as often as Sara does. 朱迪像莎拉一样时常去看电影。 old john goes to sleep as easily as a baby does. 老约翰像婴儿一样容易入睡。 the girls are as busy with their work as bees. 这些女孩子就跟蜜蜂一样忙着工作。 he is as nice a boy as peter (is). 他和彼得一样都是好男孩。 she has as many friends as mary (does). 她和玛丽一样有许多朋友。 he has as much money as john (does). 他和约翰一样有很多钱。 he is as clever as (he is) handsome. 他不但英俊而且聪明。 my teacher is as kind as (she is) intelligent. 我的老师不但善良而且聪慧。 as many/much ...

英语比较级的用法 一忌使用双重比较级 即构成比较级时不能既加词尾-er，又在其前加more。如： 他的英语比我的英语好多了。 误：His English is more better than mine. 正：His English is much better than mine. 【注】虽不能说more better, most earliest 之类的，但可用“比较级+and+比较级”这样的形式： It’s getting warmer and warmer. 天气变得越来越暖和。 I’m getting fatter and fatter. 我越来越胖了。 We’re going more and more slowly. 我们越走越慢了。 要想加强比较级的语气，可用much, far, even, still, rather等修饰。如： This is very much cheaper. 这个便宜得多。 This one is even more expensive. 这个更贵些。 The patient is much better now. 病人现在好多了。 二忌比较对象不一致 如果有人问你“一公斤苹果多还是一尺布多”时，你会怎么回答？你肯定认为无法回答。对，无法回答，因为它们“单位”不一样，或者说它们不是同一类型的两个比较对象。在使用英语的比较级时，也要特别注意不要“比”错了对象。如： Her French was no better than mine. 她的法语比我好不了多少。 My dictionary is more useful than yours. 我的词典对你的词典更有用。 All your neighbours are noisier than ours. 你们的所有邻居都比我们的吵闹。
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同的部分, 而只剩下对比的成分。 It is warmer today than it was yesterday. 今天的天气比昨天暖和。 This picture is more beautiful than that one. 这张照片比那张照片漂亮。 1. 同级比较 两个比较对象程度相同时，用“as+形容词原级+as的结构” 例如：Tom is as tall as his brother. 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，
还），a lot（许多），a little / bit（一点），rather（相当地），等等。例如： She’s a little more outgoing than me. My bike is much newer than his. 3、比较级中的两个特殊作用的结构是： a.The +比较级+ 句子，the + 比较级+ 句子。它表示的意义是"越（怎么样就）越（怎么样）"，在这个结构中的两个"比较级"不要求一定词性相同，它们各自的词性要依句子的需要而定。 例如： The harder you work at your study, the better grades you will 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. When spring comes, the weather is warmer and warmer.
比较级(comparative degree) 在比较级中，有超越、相等、差逊三个级别。 1. 超越(superiority) （1）better than: 胜过，优于 Doing is better than saying.（百说不如一做。） (2)more than + 从句。多余，超过 She has talked more than what is necessary.(她说了一些多余的话) （3）“than +关系代词”的从句。再…… 不过。 He is a scholar than whom no man ever will be more honest. （他是个再诚实不过的学者了。） （4）superior to ：占优势，比……胜一筹。 He is superior to his elder brother.(他比他哥哥强) 2. 相等(equality) (1) as …as. 如……一样。 As busy as a bee. ( 忙得不可开交) (2) as well as 。既…… 又，和……一样。 Pompey, as well as Caesar, was a great man. (像恺撒一样，庞培也是一位伟人。) (3) the same as…. 像……一样。 The same as the past. (一如从前。)
(4) such/ so…as. 像……一样。 Such a great poet as Homer was proficient not just in literature but also in history . (像荷马那样的诗人，不仅要精通文学，还要精通历史。) (5) no sooner than.. 一……就（几乎同时，夸张用法）。 No sooner said than done.(说到做到。) (6) No more than. 就像，不优于。 You’re no more capable of speaking French than I am. （你我都不会说日语。） (7) No less than. 就像，不次于。 Technology is no less important than market. (技术和市场同样重要。) (8) 否定代词+more than (else than, other than) 。than是介词，只不过……而已。 This is no other than myself. （这人就是我。） 3.差逊(inferiority) (1) inferior to. 比……差，逊于…… She in to some degree inferior to him in literary. （她比他在文学上稍逊风骚。） (2) less than.. 少于，不到 It rains less in Jinan than in Hangzhou.
1．“A + be +形容词比较级+ than + B”意思为“A比B更……”。 如：This tree is taller than that one. 这棵树比那棵树高。注意： ①在含有连词than的比较级中，前后的比较对象必须是同一范畴，即同类事 物之间的比较。 ②②在比较级前面使用much，表示程度“强得多”。 如：A watermelon is much bigger than an apple. ③very, quite一般只能修饰原级，不能修饰比较级。 2．“比较级+ and + 比较级”或“more and more +原级”表示“越来越……”如：It becomes warmer and warmer when spring comes. 春天来了，天气变得越来越暖和了。It is getting cooler and cooler. 天气越来越凉爽。 The wind became more and more heavily. 风变得越来越大。 Our school is becoming more and more beautiful. 我们的学校变得越来越美丽。 3．在含有or的选择疑问句中，如果有两者供选择，前面的形容词要用比较级形式。 如：Who is taller,Tim or Tom? 谁更高，Tim还是Tom? 4. “the +比较级……, the+比较级”，表示“越……越……”。 The more money you make, the more you spend. 钱你赚得越多，花得越多。T he sooner，the better. 越快越好。 5. 表示倍数的比较级用法： ①. A + be +倍数+ times + the + 形容词对应名词形式+ of + B. 如：The new building is three times the height of the old one. 这座新楼比那座旧楼高三倍。(新楼是旧楼的四倍高) ②. A + be +倍数+ times +as +原级+ as+ B. 如：Asia is four times as large as Europe. 亚洲是欧洲的四倍大。(亚洲比欧洲大三倍) ③. A + be + 序数词+比较级+ than + B. 如：Our school is twice bigger than yours. 我们学校比你们学校大两倍。 6.形容词、副词的最高级形式主要用来表示三者或三者以上人或事物的比较，表

新目标人教版八年级英语语法知识讲解重难点知识讲解：形容词的比较级和最高级1、 比较级的定义：大多数的形容词都有三个级别：原级、比较 级、最高级。其中比较级表示“更……”，用于两者之间的比较，用来说明“前者比后者更……”，比较级前面一般用much, even, a little修饰，其中even, much 只能修饰比较级。 二、比较级的构成： （1）规则变化： ①单音节和部分双音节的形容词一般在词尾加-er Eg: calm---calmer tall---taller smart---smarter ②以字母e结尾的直接在词尾加-r Eg: nice---nicer fine---finer large---larger ③以“辅音+y 结尾的词，变y为 i，再加-er” Eg: early---earlier happy---happier busy---busier ④以重读闭音节的单个辅音字母结尾的词，双写辅音字母，再 加-er Eg: big---bigger thin---thinner hot---hotter ⑤多音节或部分双音节的形容词在原级前面加more Eg: popular---more popular important---more important （2）不规则变化： 少数形容词的比较级变化是不规则的：good---better bad/ill---worse many/much---more little---less far---farther/further old---older/elder 三、比较级的用法: (一)当两个人或事物（A和B）进行比较时，我们需要用到形容 词（副词）的原级或者比较级 1．表达“A和B一样”，用as…as的结构。 公式: A+be动词+as+形容词原级+as…+B A+实义动词+as+副词原级+as…+B Eg I am as tall as you.我和你一样高。 He runs as fast as I. 他跑得和我一样快。 2．表达“A不如B”用not as…as的结构。 公式: A+be动词的否定形式+as+形容词原级+as…+B A+助词的否定形式+动词+as+形容词原级+as…+B Eg I am not as tall as you.我没有你高。 He doesn’t run as fast as I. 他没有我跑得快。
