形容詞的比較級專項
一、 變化規則；
1、 規則變化：（1）單音節詞和少數雙音節詞一般在詞尾加er或est：bright _____ ______; 以不發音的e字母結尾的加r,或st：large; 以輔音字母加y結尾的變y為i加er或est:easy； 以一個輔音字母結尾的重讀閉音節詞雙寫最后一個輔音字母再加er或est: big 以er，ow結尾的雙音節詞加er 或est:clever slow
（2）多音節詞前加more或most, 副詞最高級前省略the.
(3) 部分形容詞本身表示最高級，因此他們沒有比較級和最高級形式：favourite round
2、 不規則變化： good, well; bad, badly, ill; much, many; little; far; old;
注：只有少數形容詞和副詞有兩種比較級和最高級形式：clever old far
二、 形容詞各等級的用法：
1、 原級（同級）比較：as…as…; not as(so)…as…
we’ll give you as much help as we can.
she isn’t as(so)active in sports as before.
2. 比較級：表示兩者之間比…… 更……可用狀語much, a little, even等修飾： he made fewer mistakes than i did.
he is even richer than i.
3、 高級：形容詞最高級前必須加the, 副詞最高級前常省略the，后面多用of……， in……短語表示范圍：
it was the most/least interesting story i have ever listened.
he is the tallest of the three.
4、 如果在兩者之間表示“最……”時要在比較級前加the，而且還用of the two, of the pair短語：
john is the clever of the two boys.
of the two boys, john is the clever.
三、 重點與難點：
1、 as…as…結構：你和湯姆是一樣好的孩子。
you’re a boy as good as tom.=you’re as good a boy as tom.
2、 (1)too…to與 so…that sb.can’t…的句型轉換：前者為簡單句，主語只有一個，而后者為復合句，主語有兩個，試比較：
the man was too angry to be able to speak.
the man was so angry that he wasn’t able to speak.
the milk was too hot to drink.
the milk was so hot that we can’t drink it.
(2) too…to…與 not enough to句型的轉換：
he is too young to get married.=he is not old enough to get married.
the book is too difficult for me to read.=
the book is not easy enough for me to read.
3、 形容詞原級表示比較級含義：
約翰不象邁克那么苯。john is not so stupid as mike.
john is less stupid than mike.
john is cleverer than mike.
4、 用比較級表示最高級：約翰是班里最高的男生。
john is taller than any other boy in the class.
john is the tallest boy in the class.
john is taller than :any other boy.
any of the other boy.
all the other boy.
any of the others.
any one else.
