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.

英语比较级总汇大:big-bigger-biggest 小:small-smaller-smallest 大:large-larger-largest 聪明:smart-smarter- smartest 明亮:bright-brighter-brightest 昏暗:dark-darker-darkest 快:fast-faster-fastest 慢: slow-slower-slowest 热:hot-hotter-hottest 冷: cold-colder-coldest 容易:easy-easier-easiest 难: hard-harder-hardest 重:heavy-heavier-heaviest 轻:light-lighter-lightest 快乐:happy-happier-happiest 远:far-farther-farthest 早:early-earlier-earliest 迟:late-later-latest 干净:clean-cleaner-cleanest 脏:dirty-dirtier-dirtist 干燥:dry-drier-driest 潮湿:wet-wetter-wettest 新的:nice-nicer-nicest 宽:wide-wider-widest 好:good-better-best 好:well-better-best 坏:bad-worse-worst 新:new-newer-newest 许多:many/much-more-most 少:little-less-least 老:old-older-oldest 年轻:yong-yonger-yongest 短:short-shorter-shortest 长:long-longer-longest 低:low-lower-lowest 高:tall-taller-tallest 瘦:thin-thinner- thinnest 胖:fat-fatter-fattest 高（身高）:High-higher-highest 忙:busy-busier-busiest 虚弱:weak-weaker-weakest 强壮:strong-stronger-strongest 友好:friendly---more friendly---the most friendly 有趣:interesting---more interesting-- -the most interesting 小心:carefully---more carefully- --the most carefully 重要:important-- more important--- the most important 漂亮:beautiful- -more beautiful-- the most beautiful

英语中“倍数”的常用表达方式倍数表达法是高中英语教学的重点，也是历年的高考热点之一。掌握倍数的表达法对于同学们学好英：语具有重要意义。下面对倍数的几种表达法作一归纳一、用times 表示倍数（一般限于包括基数在内三倍或三倍以上的数。表示两倍的数，一般用twice ）。 ) 其句式有：(前三种为主 1. “?times＋形容词/ 副词的比较级＋than ?”例如： Line AB is three times longer than line CD. 线段AB 是（线段）CD 的三倍长。 This hall is five times bigger than our classroom. 大 5 倍。这个大厅比我们的教室 This rope is twice longer than that one ． This hall is five times bigger than our classroom ． The car runs twice faster than that truck ． 2. “?times +as +形容词/ 副词的原级＋as ?”例如： This table is three times as long as that one. 这张桌子是那张桌子的三倍长。 This dictionary is five times as thick as the one you borrowed from the library. 这本词典的厚度是你从图书馆借的那本（厚度）的 5 倍。 Asia is four times as large as Europe 亚洲的面积是欧洲的四倍。 This big stone is three times as heavy as that one ．倍）这块大石头的重量是那一块的三倍。（这块石头比那块重二 The plane flew ten times as high as the kite ．那架飞机飞行高度是那个风筝的十倍。（高出九倍） 3. “?times + the +名词（如：size ，height ，weight ，length ，width, age 等）＋of ?”例如： The earth is 49 times the size of the moon. 地球的体积是月球的49 倍。

☆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。

英语倍数的表达方法一、用times表示倍数（一般限于包括基数在内三倍或三倍以上的数。表示两倍的数用twice）1.“A + be + 倍数+ as + 形容词或副词原级+ 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+ 形容词或副词的比较级+ 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。计量名词：size大, length长, width宽, height高, depth深，weight重…倍数+the size of …… …倍数+the length of …… …倍数+the height of …… …倍数+the width of …… …倍数+the depth of …… …倍数+the weight of …… 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.“…times + that of+被比较对象” In this workshop the output of July was three times that of January. 这个车间7月份的产量是元月份的三倍。

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. 在表示两倍时，我们常用twice或double。例如： This year we have produced twice as much corn as we did last year. 我们今年生产的玉米是去年的两倍。 She is double my age. 她的年龄是我的两倍。 2. 在表示三倍或三倍以上的倍数时，我们常用times表示，能够译为"是......的几倍"；"比......大/高/长......几倍"等等。 ①用"主语+谓语+...times + the size(或amount, length...)+ of +被比较的内容"表示。例如： The size of your room is five times the size of mine. 你房间的面积是我房间面积的五倍。 ②用"主语+谓语+...times + 形容词（副词）的比较级 + than +被比较的内容"表示。例如： Your bag is twice bigger than mine. 你的包比我的大两倍。 ③用"主语+谓语+...times + 形容词+ (n.) + as + 被比较的内容"表示。例如： Your book is three times as thick as mine. 你的书比我的书厚三倍。 ④用"主语+谓语+...times + what引导的从句"表示。例如： Cotton output is now ten times what it was ten years ago. 当前棉花的产量是十年前的十倍。 ⑤用"主语+谓语+...times + upon(或over)..."表示。例如： The size of the sun is a million times over that of the earth. 太阳的体积比地球的体积大一百万倍。 3. 可用"主语+谓语+...+ as + 形容词（副词） + again + as"表示。例如： Nine is as much again as three. 九是三的倍数。 4. 可用"主语+谓语+ 倍数（百分比）"表示。例如： This year we'll learn 20% more words from our texts than we did last year. 今年我们学习的单词比去年多20%。 5. 用"主语+谓语+ to + 数词"表示"增加到......数"。例如： The number of students in our school has increased to 2001. 我们学校的学生数已增加到两千零一人。 6. 用"主语+谓语+by+数词（百分比、倍数）等"表示。例如： The cost of the paper has reduced by 4%. 报纸的成本已减低了百分之四。

一. 表达倍数的三个基本句型 1.“A+be动词/谓语动词+倍数+as+形容词/副词原级+as+B”，表示“A正好是B的多少倍”。例如： Asia is four times as large as Europe. 亚洲的面积是欧洲的四倍。 This big stone is three times as heavy as that one. 这块大石头的重量是那块的三倍。 The plane flew ten times as high as the kite. 那架飞机的飞行高度是那只风筝的十倍。 2. “A+be动词/谓语动词+倍数+形容词/副词比较级+than+B”，表示“A比B大（长、高、宽等）多少倍”。例如： This rope is twice longer than that one. 这根绳子比那根绳子长两倍（是那根绳子三倍长）。 This hall is five times bigger than our classroom. 这个大厅比我们的教室大五倍(是我们教室的六倍大)。 The car runs twice faster than that truck. 这辆小车的速度比那辆卡车快两倍（是那辆卡车的三倍快）。 3. “A+be动词+倍数+the size/height/length/width, etc+of+B”，表示“A正好是B的多少倍”。例如： This street is four times the length of that one.这条街是那条街的四倍长。 This hill is four times the height of that small one.这座山的高度是那座小山的四倍。除表达倍数的三个基本句型外，我们还要掌握其基本句型的7种变形。 1. “ ... times as many/much+名词+as+被比对象”。例如： There is four times as much water in this pot as in that one.这个壶里装的水是那个壶里的四倍。 There are six times as many students as we expected.学生数量是我们预期的六倍。 2. “ ... times+more+名词（可数或不可数）+than+被比对象”。例如： There are five times more books in our library than in yours.我们图书馆里的书比你们图书馆多五倍多。 We have produced twice more grain this year than we did last year. 我们今年生产的粮食是去年的两倍多。 3.“ ... times+over+被比对象”。例如： The grain output in that village is twice over that of 2002. 那个村的粮食产量是2002年的两倍多。 4. “ ... times+that+of+被比对象”。例如： In this workshop, the output of July was times that of January. 这个车间7月份的产量是1月份的倍。 5. “...times+compared with+被比对象”。例如： The number of the students in our school has increased 4 times compared with 1980. 我们学校的学生人数比1980年增加了四倍。 6. “...times+what+从句”。例如： The production is now three times what it was ten years ago. 现在的产量是十年前的三倍。

比较级& 最高级一、形容词的比较级 1、形容词比较级在句子中的运用：两个事物或人的比较用比较级，比较级后面一般带有单词than。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。）比较级前面可以用more, a little 来修饰表示程度。than后的人称代词用主格（口语中可用宾格）。 2．形容词加er的规则： 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以一个元音字母和一个辅音字母结尾，双写最后的字母再加er，如big--bigger, thin--thinner ,hot–-hotter， sad--sadder，fat—fatter 3．不规则形容词比较级： good--better, beautiful--more beautiful， expensive--more expensive 二、副词的比较级 1．形容词与副词的区别 (有be用形，有形用be；有动用副，有副用动) ⑴在句子中形容词一般处于名词之前或be动词之后。 ⑵副词在句子中最常见的是处于实义动词之后。 2．副词比较级的变化规则基本与形容词比较级相同 ☆注意☆ 1、比较的两者应该是互相对应的可比较的东西。典型错误：My hair is longer than you.（我的头发比你更长。）比较的两者是我的头发、你（整个人），那么比较的对象就没有可比性。应该改为：My hair is longer than yours. 或My hair is longer than your hair. 2、如果比较的两者是一样的时候，我们会用as…as…这个词组。它的用法是：什么+be+as+形容词原形+as+什么，意思是什么和什么一样……。如： I'm as tall as you.（我和你一样高。） My feet are as big as yours.（我的脚和你的一样大。）一、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）
