He works (the) hardest in his class.注意：当最高级的前面无限定词the或有不定冠词a/an时，仅表示“很，非常”Monday is my busiest day.星期一是我很忙的一天。Qingdao is a most (very) beautiful coastal city.青岛是一个非常美丽的海滨城市。6. 比较级与最高级的转换： Mike is the most intelligent in his class. Mike is more intelligent than any other student in his class7.as.as的用法：1)两者相比（甲=乙），用“as+原级+as”表示Tom is as tall as Mike.2)两者相比（甲 乙），用“not as(so) +原级+as”或“less than”表示I didnt do my homework so(as) carefully as you.The picture is less attractive than that one.三.典型例题 1） - Are you feeling _? - Yes，Im fine now. A. any well B. any better C. quite good D. quite better 答案：B. any 可修饰比较级，quite修饰原级，well的比较级为better. 2）The experiment was_ easier than we had expected. A. more B. much more C. much D. more much 答案：C. much可修饰比较级，因此B，C都说得通，但easier本身已是比较级，不需more，因此C为正确答案。 练习：一. 词形变换。 比较级 最高级large _ _fast _ _easy _ _ 比较级 最高级wet _ _good _ _important _ _well _ _bad _ _many _ _little _ _far _ _strong _ _patient _ _safe _ _expensive _ _二单选题（ ） 1 Tom is one of _ boys in our classA tallest B taller C the tallest D the tall( ) 2 English is one of_ spoken in the worldA the important languages B the most important languages C most important language D the most important language( )3 Mary studies harder_ in her classA as any one B than any other girl C than the other D than anyone( )4._ I look at the picture， _ I like itA The best； the more B The more； the lessC The more； less D More； the more（ ）5.
