习最用功“为例，可有以下几种表达：

　　He studies hardest in his class.

　　He studies harder than any other student in his class.

　　He studies harder than any of the other students in his class.

　　He studies harder than all the other students in his class.

　　He studies harder than any of others in his class.

　　He studies harder than any one else in his class.

　　He studies harder than the others in his class.

　　He studies harder than the other students in his class.

　　但是若比较的双方不在同一范围内,则不需要other 来排除了。

　　如：China is larger than any country in Africa。

　　中国比非洲任何国家都大(中国不在非洲,故any后不要other)

　　2.not so/as…as…可与less…than或more…than…互换。如：

　　I think math is not as/so interesting as English。

　　= I think math is less interesting than English。

　　=I think English is more interesting than math。

　　我认为数学没有英语那样有趣。

　　在使用not so/as…as…结构时,如果句子中的谓语动词是实义动词,not应与助动词do的适当形式连用，而不能直接接在谓语动词的后面.如：

　　误：He gets up not so/as early as Jim。

　　正：He doesn’t get up as/so early as Jim。

　　3.much,a little, even, still等表示程度的副词可用来修饰比较级，而very, too, so, quite(表示身体健康的quiter除外)习惯上不用来修饰比较级。如：

　　误：I think science is very more difficult than Chinese.

　　正：I think science is much more difficult than Chinese.

　　清单三：形容词的顺序

　　当多个形容词同时修饰一个名词时，通常按这样的顺序：限定词+描绘性的形容词+大小+形状+新旧或年
