You’re a boy as good as Tom.=You’re as good a boy as Tom. （3）表示倍数：倍数+as+原形+as Our school is twice as big as yours. 2．比较级的用法 （1）…+ the+形容词比较级+of the two(+名词)表示“两者中更……”。如： The apple is the bigger of the two. 　 这个苹果是两个中较大的。 The boy is the taller of the two students.　 这个男生是这两个学生中个子较高的。 注意：形容词比较级前可用much，even，still，a little，a lot等来修饰，表示“……得多，甚至……，更……”。 He is a 1ittle younger than me.他比我小一点。 （2）“The+形容词比较级..., the+形容词比较级...”表示“越……就越……”。如： The more you study, the more you know.　　 学的越多，就知道的越多。 The more friends you have, the happier you are.　 你的朋友越多，你就越开心。 （3）“形容词比较级+and +形容词比较级”表示“越来越……”。如：　　 It’s getting hotter and hotter.　　 天气越来越热了。 The computer is cheaper and cheaper. 计算机越来越便宜。 3．最高级的用法 （1）形容词最高级作表语通常要加the。有时不用the，表示“极，很，非常，十分”。 如：　　 It’s most dangerous to be here.　　 在这儿太危险。　　 I cannot do it, it’s most difficult.　　 我干不了这件事，太难了。 （2）形容词最高级作定语修饰名词时，如这个名词前面有物主代词或所有格，那么the必须省掉。如： Monday is my busiest day in a week.? 星期一是我一星期中最忙的一天。 Jack is Jim’s best friend.Jack是Jim最好的朋友。 （3）最高级和比较级之间的转化。如： He is the tallest in our class. =He is taller than any other student in our class. 他是我们班个子最高的。 （4）“序数词+最高级+可数名词单数”表示“第几……”。如： The Yellow River is the second longest river in our country. 黄河是我国第二长的河流。 　 　英语语法之形容词比较级和最高级练习题 This box is___ that one.　A. heavy than B. so heavy than　 C. heavier as D. as heavy as 2 When we speak to people, we should be .　A. as polite as possible B. as polite as possibly　　C. as politely as possible D. as politely as possibly 3 This book is____ that one, but____ than that one.　A. as difficult as; expensive B. as more difficult as; more expensive　　C. as difficult as; more expensive D. more difficult as; as expensive 4 I think the story is not so ___ as that one.　A. interesting B. interested C. more interesting D. most interesting 5 His father began to work____ he was seven years old.　A. a
