副词最高级和形容词最高级
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-er,-ow结尾的双音节词,比较级面加-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. ③ very, 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.

The more money you make, the more you spend. 钱你赚得越多,花得越多. The sooner,the better. 越快越好. 5. 表示倍数的比较级用法： ①.

This hat is nearly \\\/ almost the biggest. 注意： a. very可修饰最高级,但位置与much不同. This is the very best. This is much the best. b. 序数词通常只修饰最高级. Africa is the second largest continent. 8.要避免重复使用比较级.

形容词比较级和最高级的不规则变化有哪些
变化规则 大多数形容词和副词有比较级和高级的变化，即原级、比较级和高级，用来表示事物的等级差别。
原级即形容词的原形，比较级和高级有规则变化和不规则变化两种。
(1)单音节词加词尾-er，-est来构成比较级和高级。
tall(高的) taller tallest great(巨大的) greater greatest (2)以不发音的e结尾的单音节词只加-r,-st nice(好的) nicer nicest large(大的) larger largest able（有能力的) abler ablest (3)以一个辅音字母结尾的闭音节单音节词，双写结尾的辅音字母，再加-er，-est big(大的) bigger biggest hot热的) hotter hottest red红色的 redder reddest (4)以辅音字母+y结尾的双音节词，改y为i，再加-er，-est easy(容易的) easier easiest busy(忙的) busier busiest (5)以ly结尾的副词，除early-earlier-earliest，其他都是加more most. Slowly-more slowly-most slowly Bravely-more bravely-most bravely quickly-more quickly-most quickly (6)少数以-er，-ow结尾的双音节词未尾加-er，-est clever(聪明的) cleverer cleverest narrow(窄的) narrower narrowest (7)其他双音节词和多音节词在前面加more，most来构成比较级和高级。
如： important(重要的) more important most important easily(容易地) more easily most easily (8)一些词的比较级和高级，可以加-er或 -est，也可以加more或most，如：clever, polite等。
(9) 不规则变化 有一些词的比较级、高级变化是不规则的，需要特殊记忆。
如： good \\\/ well→better→best bad \\\/ ill\\\/badly→worse→worst many \\\/ much→more→most little→less→least far→farther→farthest(表示距离) \\\/ far→further→furthest (表示程度) old→older \\\/ elder→oldest (表示新旧或年龄) \\\/ eldest (表示兄弟姐妹之间的长幼关系) 副词的比较级和高级的构成规则和形容词比较级和高级的构成规则一样，所不同的是：形容词高级前面必须用the，而副词的高级前面的the可带可不带。
一些词本身没有比较级和高级形式，如：right, wrong, full, empty, round, complete, wooden, dead, daily等。
