专题二 需要“变形”的名词、数词、形容词和副词
第二讲 形容词、副词和比较级
考点分类突破
In my family,my mother is the thinnest①.My father is much taller② than her and me,but he is twice as heavy as③ my mother,and becoming fatter and fatter④.He is quite worried because the fatter⑤ he is,the more likely⑤ he is to be ill.
注释:
①两者或两部分之间比较,多用比较级;三者或三者以上的比较,可以使用最高级。
②比较级常常和than连用,并且可以被much,a little,a bit,even,far,still 等词修饰。
语境导入
③倍数表达法:
A+谓语+倍数+adj./adv.比较级+than+B
A+谓语+倍数+as+adj./adv.原级(+名词)+as+B
A+谓语+倍数+the+名词(size,length,height,weight等)+of+B
④“adj./adv.比较级+and+adj./adv.比较级”表示“越来越……”。
⑤“the+比较级 ...,the+比较级 ...”表示“越……,就越……”。
1.形容词比较等级的规则变化
重难精析
变化规则 例词
单音节的词,一般在后面加-er和-est tall→taller→tallest
quick→quicker→quickest
以“辅音字母+-e”结尾的词,在后面加-r和-st wide→wider→widest
fine→finer→finest

多音节词在前面加more和most attractive→more attractive→most attractive
[易错提醒]
有少数几个双音节以及-er,-le结尾的词,既可以加-er和-est,又可以加more和most构成比较级和最高级。如:common,clever,simple,stupid等。
