比较级的用法

比较级的构成规则 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，比较级在原级后加-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。 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（well）→better→best bad（ill）→worse→worst

old→older/elder→oldest/eldest many/much→more→most

little→less→least far →further/farther→ furthest/farthest

原级比较：表两者程度相同,用as+adj/adv+as表示，否定形式：not as/so+adj/adv+as。 Dick is as tall as his brother. Tom speaks as quickly as his cousin. I have never seen a person as / so clever as he is.

比较级：1. 表示A超过B: 形容词和副词的比较等级+than

Our classroom is brighter than yours. Dogs run faster than rabbits.

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类事物之间的比较。 ②比较级前用much，表程度“强得多”。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. 表示A不如B：less+形容词/副词的原级+than

Rabbits ran less fast than dogs. Jenny is less clever than her sister. 3形容词和副词比较级的特殊用法
