比较级和最高级的英语教学课件
比较级和最高级的英语教学课件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：在形容词或副词前力口more( 如more natural,more clearly ) 或加后缀-er(newer,sooner )。

clever-cleverer/more clever-cleverest/most cleverestcommon-commoner/more common-commonest/most commonsimple-simpler/more simple-simplest/most simple②有些形容词没有程度可分或本身就表示某种极限程度，故没有比较级和最高级。
如：right/correct（正确的），wrong/false（错误的），final（最后的），impossible（不可能的），wooden（木制的），empty（空的），excellent（优秀的），unique（独一无二的），perfect（完美的），complete（完全的），absolute （绝对的）等。
02 不规则变化[注]①older/oldest与elder/eldestolder/oldest既可用于指年龄、新旧上“更老的；更旧的/最老的；最旧的”，也可用于指血缘上“年纪较长的/最年长的”，elder/eldest则只用于指人“年纪较长的/最年长的”，且不用于比较句型，通常置于名词前作定语，不作表语。

语法专题比较结构
语法专题（七）比较结构一、比较等级和比较结构比较等级是指形容词和副词有原级、比较级和最高级之分。
而比较结构是指运用形容词和副词的级别，对两种或两种以上的事物进行比较的短语结构。
根据比较级别可以分为三类：一是表示某物和某物一样；二是表示某物比另外某物更加怎么样；三是表示某物最怎么样。
下面我们分别来看表示这三种比较的英语结够有哪些。
二、三种比较结构（一）原级：as …as结构, 具体在句子中，就有两种应用形式：A is as +adj asB 或者：A do B as + adv + asC (do).Mary is as tall as Betty.I drove as carefully as Tom did.好，我们来看一下这种结构的一些变化形式：1）否定式：A is not as/so + adj + as B；或A do not do B so/as + adv + as C (do).Mary is not so tall as Betty.I did not drive as carefully as Tom did.2) as +many/much + 名词+ asThere are as many students in our class as in their class.We have as much snow this year as last year.3) A is as + adj + a/an + 名词+ as BMary is not as beautiful a girl as Betty.I just want to read as interesting a book as that one.4) A is a/an + 名词+ as + adj + as B.实际上这是将上面第3）种的名词提前，这样as + adj + as B就变成了后置定语。
Mary is not a girl as beautiful as Betty.I just want to read a book as interesting as that one.5）A is as+adj(1) as A is+adj (2).注意：（1）这是as….as…结构比较特殊的用法，是指将同一事物就其两个不同的方面进行比较, 所以结构中的两个形容词是不同的。
比较级及比较句型讲义
比较级及比较句型一．基本特征1. 形容词和副词比较级的形式应和比较连词对应出现;即应符合原级比较及比较级的结构..如：---Do you enjoy listening to records---I find records are often as good as; or better than an actual performance.Young readers; more often than not; find the novels of Dickens far more exciting than Thackeray’s.---- Thackeray’s novels3.比较级的修饰语如 a little; a lot; the; any; even; far; hardly; lots; much; rather;还有表示倍数比较的词等;他们的位置是：修饰语+as…as…; 或修饰语+more…than…..如：Smoking is so harmful to personal health that it kills seven times more people each year than automobile accidents.“Do you regret paying five hundred dollars for the painting” “No;I would gladly have paid twice as much for it.”4.下列词和短语不用比较级形式却表示比较概念：inferior;minor;senior;prior;preferto;superior;major;junior;preferable;differ from;compared with;in comparison with;different from;rather than..如：Their watch is superior to all the other watches on the market.二．基本用法1. 同级比较A. 基本形式“as +原级+as”结构eg. He’s as tall as I.B.否定的同级比较常用not as… as或not so … aseg. He does not smoke so heavily as his brother.C.变体1 as + much/many + 名词+ asThere are as many students in Class 3 as in Class 4.2 as +形原级 + a + 名词 +asHe is as clever a boy as his brother.3 as + 形+ 不可数名词+ as4 名词复数+as +形 + asI used to have some dolls as lovely as yours.5 the same as/ be similar to2.比较级A.基本结构“比较级+than” 结构He is taller than I am tall.She sees me more often than she sees her brother.B.变体1 形比较级 + 名 + thanHe is a cleverer boy than his brother.2 名 + 形比较级 + thanHe is a boy cleverer than his brother.3 the + 形比较级 + of + the two4 superior/ inferior to3.最高级A. 常用“the +最高级+比较范围”eg. This is the best picture in the hall.He sings the best in the class.B. 变体1 more… than any other2 Not … + 比较等级三. 值得注意的比较级句型1. 比较级的特殊用法1the+比较级; the+比较级此句型表示后者随着前者的变化而变化;意为“越……就越……”;如：The better I knew him; the more I liked him.; the less likely I’ll be able to answer them.该结构一共有三条规则：1. the morethe more; the more其实是原因状语从句;前面是原因从句;后面是结果主句;倒装句中必须是主句倒装;从句绝对不能够倒装..例1：The stronger __ magnet; the greater the number of lines of magnetic force.A ofB theC is theD is of the分析：本题显然考查”the more … the more…”结构;the more后面的名词必须使用冠词或者所有格;因此只能选择B例2：The less the surface of the ground yields to the weight of the body of a runner; ___to the body.A the stress it is greaterB greater is the stressC greater stress isD the greater the stress分析：正确答案为D..此题考the more … the more句型;只有D符合这一句型的要求;故选D..--- the greater the stress it yields to the body2 the+比较级+of the two：He is the taller of the two.She was the more promising worker of the two.3比较级+and+比较级此句型表示“越来越…”;如：Things are getting better and better every day.It’s becoming more and more difficult to find a job.2. as…as…的特殊用法1．as．．．as．．表示两个事物的状况处于同等程度或两个事物之间具有连带关系..S1 + V1 + as + adj. 1+ S2+V2+adj.2He was as experienced as his brother was green．他经验丰富;而他弟弟初出茅庐..She is as kind as her brother is honest．crowded as the farmlands are empty．监狱里人满为患;而农田却无人耕种..两者程度相等;但是状况截然不同;以突出两者的对比2．as．．．as．．表示两个特征同时存在;具有both．．．and．．．的含义..S +V+as + adj. 1+ as +adj.2S+V+as +n.1+as +n.2The problems are as numerous as trivial．It is as your fault as your wife‘s．3．as．．．as．．．can be; as．．．as anyanything; as．．．as ever lived：表示某事达到了无以复加的程度;最;极其..They are as unreliable as they can be．He is as great a mathematician as anyas ever lived．My sister is as green as green can be．He pretends to be as modest as anything．4as likely as not：该结构并无否定含义;表示很可能之意;而且语气强烈..例如：He will forget all about it as likely as not．类似的用法还有：as often as not;more often than not;表示经常、往往之意..3．not so much ．．．as．．．：这个句型用以肯定as后面的内容;而在一定程度上否定as前面的内容;表示“与其说还不如说” ..Experience shows that success is not so much due to ability as to passion． ---- not so much due to ability as due to passionI was attracted not so much by the plot of the story as by the actor’s excellent performance．4．1 As C is to D;so is A to B．：这个句型表示A与B之间的关系就像X与Y之间的关系;以人们所熟知的两个事物之间的关系说明一个不被熟知或被忽视的两事物之间的关系;是一种类比：A 对于B;犹如X对于Y..例如：As the house is to the man;so is the nest to the bird．As food is to the body;so is reading to the mind．2 A is to B what C is to DThe people is to the Party’s army what water is to fish.Reading is to the mind what exercise is to the body.5．more than与less than的相关特殊用法1more A than B：表示与not so much．．．as类似的含义;肯定的是A;而在一定程度上否定B.. “与其说是B;还不如说是A”..He is more brave than wise．The child was more frightened than hurtMany patients die more of worry than of cancer when they get to know the truth about their illness．2 more…than…的特殊用法对同一对象的两个方面进行比较：若是对同一个人或物在不同方面进行取舍时;意为“与其说……倒不如……”;..如：He is more hungry than tired.I was more annoyed than worried.3more than ＋名词／形容词／分词：表示内容超出了后面词语所表达的范围; “不只于;超过;极其”..例如：If you tell your father what you’ve done; he‘ll be more than a little angry．We were more than happy to hear of your return．4 no more…than与not more…thannot more…than指两者虽都具有某种特征He is no more a writer than a painter. = He is neither a painter nor a writer.He’s no more able to read Spanish than I am.=Neither he nor I am not read Spanish.This book is not more difficult than that one.=This book is not so difficult as that one.5 no more …than 与no less…thanno more …than意为“与…一样不”;否定两者；She’s no more a great singer than I am.他不是优秀歌手;我也不是..Your brother is no less wise than you.你的兄弟跟你一样聪明..6 not +比较级+ than /no +比较级+ than比较级前加比较级前加no与neither…nor…或“as+相反意义的形容词或副词+as”相当..如：He is not taller than me.He is no taller than me.他同我一样不高..即一样矮His English is not better than mine.His English is no better than mine.他的英语同我的英语一样不好..即一样差7 no more than与not more than表示数量时no more than“仅仅”、“只不过”;强调少；not more than表示“不多于”、“至多”..无强调This test takes no more than thirty minutes.For thirty years;

只有D符合条件..注意空格后为倒装形式;do代替emit以避免重复..此题为常考的句子结构..2、对称性比较结构中还需要注意相互比较的必须属于同一种事物;例例3：The activities of the international marketing researcher are frequently much broader than___.A the domestic marketer hasB the domestic marketer doesC those of the domestic marketerD that which has the domestic marketer分析：本题还是考查比较句;由于谓语动词是系动词are; 故先排除与其不对应的以has和does结尾的A和B..选项D则语义不清;也可排除..C中those代替前面提到的activities以避免重复;those一定要具备;因为只有这样才能满足比较的都是activities;谓语动词are因与主句谓语动词相同而被省略;因此C为正确答案..例4：The annual worth of Utah's manufacturing is greater than --.A that of its mining and farming combinedB mining and farming combinationC that mining and farming combinedD of its combination mining and farming分析：本题为比较句;一般来说;比较的双方应属于同一类事物..B、C、D均无法与the annual worth相对应;故可以排除..A中代词that代替 the annual worth; 是英语中常见的避免重复的用法;故选A..3. 省略性than和as引导的比较状语从句;如果意义明确;than和as后面的任何部分都可省略..A．当不同的主语进行比较时;一般省略从句中的谓语；1 He is taller than his brother is .2 You hate him as much as I hate him .3We were as fortunate as them they wereB．当从句中的主语与谓语 be 动词除外和主句中的主语与谓语相同时;通常省略从句中的主语和谓语;只保留比较的部分..1 My mother is much better now than she was when I wrote to you last week.2 I have as much confidence in you as I have confidence in him.3 We are less credulous than we used to bethan 后面省略了表语--- than we used to be credulousC. 从句中的主语和谓语与主句的都不相同;有时可以省略主语或将than看作代词作为从句的主语..1He eats more than it is good for him.2She has finished the work earlier than it has been expected.3There were not so many tickets available as they were asked for.。

比较级
25.2 比较结构
1）as ...as 结构
这种结构的基本模式是as +|形容词或副词原级+as分句 例如： John is as bright as Bob. 这种比较结构的否定形式是： Jon is lessbright than Bob. 以上否定形式可以用less...tha结构来表示： John is less bright than Bob. 此外。带有as...as结构的句子也可能主语相同，而比较项目不同。例如： The girl was as brilliant as she was beautiful. 也可能两个主语和两个比较项目都不同，计量各不同的人或物就不同的方面进 行比较，例如： This swimming pool is not twice as wide as that one is long. As...as结构的另一种模式是：as much\many+名词+as分句，这是many\much 是限定词。 例如： He took as much butter as he needed. As...as结构还有一种便提醒是，这就是AS+形容词原级+名词词组+AS分句。例 如： George is as efficient a work as Jack.
25.3 关于比较结构的补充用法
1） more... Than 结构的其他用法
More..than 结构除在两人或物之间比较外，还可以在同一个人 或物的本身做不同方面的比较 [1]The corcer was more enjorable than the lecture. [2]The living room is larger than the dining room. [3]He was less hurt tha frightened. (与其说他受伤害，不如说他受惊吓。）
九年级英语形容词、副词比较等级的讲解与用法
形容词、副词比较等级的讲解与用法形容词与副词的比较等级1) 同级比较往往由"as + 形容词/ 副词的原形+ as"的句式表达；当然也要注意它的否定形式、以及在第一个as前加倍数或程度副词的情况。
2)"比较级+ than"引导不同级的比较。
"比较级" 前同样可以加倍数或程度副词。
另外"no more …than"意思是"A和B一样不……" 。
3) 形容词的最高级前一般必须有定冠词the；但是也有不加定冠词the的几种情况。
4) 要注意几种比较级的特殊句型，如："the + 比较级…，the + 比较级……"，意思是"越……越……"；以及"比较级+ and + 比较级"意思是"越来越…"，等。
英文中的形容词和副词一般都有三种级的形式即：原级（The Positive Degree），比较级（The parative Degree）和最高级（The Superlative Degree）。
5）同级比较中有两种情况：# 表示双方情况"一模一样"，用as + 原级+ as的结构；# 表示双方情况"不（那么）一样"，用not so / as + 原级+ as的结构。
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：My parcel is as heavy as yours . 我的包裹与他的一样沉。
Arther calculates as accurately as a calculator.阿瑟象计算器一样计算精确。
His bedroom is not as neat as his sister's. 他的寝室没有他姐姐的整洁。
