He is no richer than Peter. 他不比彼得富裕多少.=He is as poor as Peter. 他和彼得一样穷.表示前者比后者强一点时,通常采用a little,a bit等. The room is a bit larger than that one.这个房间比那个稍大一点.4) 表示前者比后者强很多时,通常采用much,even,still等.(still修饰形容词,副词的比较级时,可以位于比较级之前或之后.) He works still harder than ever. =He works harder still than ever.他比以往更加努力学习了.5) 表示前者在某方面远远地超过对方时,通常采用far,by far,a lot,a great deal等. Matters are a lot better than ever before. 情况远远比以往好.6) 在否定句,疑问句或条件状语从句中,修饰形容词,副词的比较级,只能用any来修饰. He cant jump any higher. 他不能跳得更高了. Can he jump any higher? 他能跳得更高一些吗? Do you feel any better today? 你今天感觉好一点了吗？ If you can jump any higher, I will give you a prize.如果你能跳得更高些,我就奖励你.7) 比较级前还可加其他表示数量的词： My sister is ten years younger than me. 我妹妹比我小十岁。典型例题:1）- Are you feeling _? - Yes，Im fine now.A. any wellB. any betterC. 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。3）If there were no examinations, we should have _ at school.A. the happiest timeB. a more happier timeC. much happiest time D.a much happier time答案：D。 4）Your house is _ bigger than ours.A. Two timeB. Second time C.

(谚语) 谁笑在最后谁笑的最好。Of the four of us, I sang (the) worst. 我们四人中我唱的最差。（四）副词比较级和最高级的一些特殊用法：副词比较级和最高级还可用在一些特别结构或短语中。1）more and more 越来越: It rained more and more heavily. 雨下得越来越大了。 She went farther and farther away. 她越走越远了。2）the morethe more 越，越： The more I work, the more I accomplish. 我干得越多，完成的就越多。3）had better (not) do sth最好(不要)做某事：Wed better not disturb him. 我们最好不要打扰他。What had we better do? 我们最好怎么办？三、基础知识练习（一）.单项选择题。1.Im shortsighted and I cant see the words on the notice board _.A, clear B, clearly C, carefully D, good2.Jean works hard but she doesnt work _ Mary.A, as harder than B, as hard than C, as harder as D, as hard as3.This is _ book in our library.A, the most interesting B, most interesting C, the more interesting D, more interesting4.Do you think maths is _ important than English?A, very B, as C, more D, quite5.They got a Christmas tree and it was _ ours.A, so tall as B, so taller as C, as tall as D, as taller as6.Tom failed in the exam.
