(对) He is more clever than his brother. (对) He is cleverer than his brother. （2）要避免将主语含在比较对象中。 (错) China is larger that any country in Asia.

She is taller than her two sisters. She is the taller of the two sisters. ※可修饰比较级的词 a bit, a little, rather, much, far, by far, many, a lot, lots, a great deal, any, still, even等。 ▲the + 最高级+ 比较范围 （1）The Sahara is the biggest desert in the world. ※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。 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. 注意：使用最高级要注意将主语包括在比较范围内。 (错)Tom is the tallest of his three brothers. (对)Tom is the tallest of the three brothers. （2）下列词可修饰最高级：by far, far, much, mostly, almost This hat is nearly / almost the biggest. （3）句型转换： Mike is the most intelligent in his class.

2017年中考英语：形容词的比较级和最高级
2017年全国中考英语：形容词的比较级和最高级 1、（2017?西宁）---Many boy students think math is ______ English. ---I agree. I'm weak in English. （） A. much difficult than B. so difficult as C. less difficult than D. more difficult than 【考点】形容词的比较级和最高级。 【分析】--许多男生认为数学不如英语难。--我赞成。我英语很差。 【解答】答案：C 联系汉语意思可知，这是math（数学）和English（英语）两者作比较，应该使用比较级。根据I agree. I'm weak in English可知，下文赞成上文的说法，表示数学不如英语难，所以此处应用表示"不如…难"的意思。又知much difficult than有语法错误，much修饰比较级；so difficult as意为和…一样难；less difficult than意为不如…难；more difficult than意为比…更难。所以此处应用less difficult than。故选C。 2、（2017?荆州）---How was your interview for the work？ ---Oh，I couldn’t feel any . I hardly understood most of the questions they asked. （） A. harder B. happier C. better D. worse 【考点】形容词的比较级和最高级。 【分析】翻译：你的工作面试怎样？哦，我感觉不能再糟糕了。我几乎不理解他们问的大部分的问题。 【解答】答案：D. harder是更难的意思，happier是更开心的意思，better是更好的意思，worse是更差的意思，因为下句是I hardly understood most of the questions they asked（我几乎不理解他们问的大部分的问题），所以该用感觉更差，故选D。 3、（2017?张家界）No mountain in the world is as ________ as Qomolangma. A. high B. higher C. highest

重点中学英语语法讲义比较级、最高级
重点中学英语语法讲义-比较等级 一、概说 英语中的形容词和副词有三个等级，即原级、比较级和高最级。比较级主要用于两者比较，最高级主要用于多者比较。 二、形容词比较等级的构成 1. 通过加后缀-er和-est构成。单音节和部分双音节形容词通过加后缀–er和-est构成比较级和最高级 原级比较级最高级 tall(高) taller tallest quiet(安静的) quieter quietest narrow(狭窄的) narrower narrowest 注：(1)若原级以字母e结尾，则只加-r和-st：fine—finer—finest。 (2)若原级以―辅音字母+y‖结尾，则应将y改为i，再加-er和-est构成比较级和最高级：dry—drier—driest。(例外：shy(害羞的)—shyer—shyest) (3)若原级为重读闭音节结尾，且末尾只有一个辅音字母，则双写这个辅音字母后加词尾-er和-est构成比较级和最高级：big—bigger—biggest。 2.通过在其前加more和most构成。多音节和部分双音节形容词通过在其前加more和most构成比较级和最高级： 原级比较级最高级 difficult(困难的) more difficult most difficult dangerous(危险的) more dangerous most dangerous 注：(1)有的双音节形容词(如 clever, common, gentle, handsome, happy, narrow, polite, quiet, shallow, simple, stupid)可以有两种方式构成比较级和最高级级：clever—cleverer / more clever —cleverest / most clever 等。 (2)某些带有否定前缀un-的三音节形容词(如uncommon, unhappy, unpleasant, untidy等)可以用两种比较级形式：unhappy—unhappier / more unhappy — unhappiest / most unhappy。 二、副词比较等级的构成 副词的比较等级的构成方法与形容词比较等级的构成方法基本一样，即： 1. 通过加后缀-er和-est构成。单音节和个别双音节副词通过加后缀–er和-est构成比较级和最高级 high(高) higher highest soon(快) sooner soonest early(早) earlier earlier 注：有关将y改为i，再加-er和-est的规则以及双写末尾辅音字母的规则，参见形容词比较等级的构成方法。
