英语形容词比较级和最高级讲解与练习
初中英语形容词比较级和最高级讲解与练习在英语中元音特别响亮，一个元音（a e i o u共五个）可构成一个音节，一个元音可以和一个元音构成音节，一个元音和一个或几个辅音音素结合也可以构成一个音节。
英语单词音节是根据单词中所包含的元音——请注意不是元音字母——来划分的。
一般来说，一个单词中有几个元音，也就有几个音节。
如not，map，have，life，night，twelfth都是单音节词；像sleep，heart，wheat，weak，coat，join，pear这样的单词，其中的元音字母都是共同发一个元音，也是单音节（注：双元音也要看做一个元音）。
（这样的单词从语音学来讲应划归“字母组合音节”。
英语的单词可分为七种音节——开音节、闭音节、r音节、re 音节、双r音节、成音节、字母组合音节。
）像begin，about，ago，royal，ancient，modern这样的单词都属双音节。
但是要注意，在middle，little，apple，castle，simple，able，saddle这样的单词中，尽管只有一个元音，也是双音节词，原因是词尾的（注意：只能是在词尾时）“辅音字母+le”中就是没有元音，也构成音节，被称作“成音节”。
由元音字母a，e，i，o，u，y（一般都说英语只有五个元音字母，其实是六个）与辅音字母R（-ar，-er，-ir，-or，-ur，-yr）构成的音节叫作"R音节“。
如：car，bar，mark，dark，her，shirt，girl，sir，sport，short，torch，nurse，burn，purse等。
像murder，prefer，martyr，grammar，doctor，person，girdle，article，artificial等单词中的-ar，-er，-ir，-or，-ur，-yr都属"R音节“。
而由元音字母a，e，i，o，u，y与RE（-are，-ere，-ire，-ore，-ure，-yre）构成的音节叫作"RE音节“。
比较级最高级讲解及练习
形容词，副词比较级和最高级讲解一、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、比较级最高级的构成1. 通过加后缀-er和-est构成。
单音节和部分双音节词通过加后缀–er和-est构成比较级和最高级原级比较级最高级tall(高) taller tallestquiet(安静的) quieter quietestearly(早) earlier earliest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 difficultdangerous(危险的) more dangerous most dangerousbravely(勇敢地) more bravely most bravely注：(1) 有的双音节词(如clever, common, gentle, handsome, happy, narrow, polite, quiet, shallow, simple, stupid，often, seldom)可以有两种方式构成比较级和最高级级：clever—cleverer / more clever —cleverest / most cleveroften—more often / oftener—most often / oftenest。

（word完整版）英语⽐较级和最⾼级讲解及练习⽐较级和最⾼级的讲解变化规则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→smallestshort→shorter→shortesttall→taller→tallestgreat→greater→greatest（2）双⾳节词如：clever→cleverer→cleverestnarrow→narrower→narrowest2．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→ablest3．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→fattest4．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→heaviestbusy→busier→busiest happy→happier→happiest5．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 beautifuldifferent→more different→most differenteasily→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"。
