much,far等程度副词在比较级中的使用　

much,far,still ,a little ,a bit等程度副词可用来修饰比较级，表示加强或减弱程度。下面就着重解析下much,far等程度副词在比较级中的使用。

1.Very一般修饰形容词的原级，而不能用来修饰形容词的比较级。修饰比较级我们习惯性用到程度副词,如：much,far,等，通常放在比较级前面。
My boyfriends is much/far older than 　　me.　　(NOT...very older than me.)我的男朋友比我大很多。
Russian is much/far more difficult than Spanish.俄语比法语难很多。

2.very much,a lot,lots,any,no,by far,a little,a bit,rather等副词也可以修饰形容词比较级，如：
Very much nicer好很多
a lot happier开心很多
rather more quickly相当的快
a little less expensive一点点贵
a bit easier简单一点
Is your mother any better?你的母亲好点了吗？
She looks no older than her daughter.她看起来一点也不比她女儿老。

【注】（1）no在修饰比较级时,在意义上否定两者,表示前者在某方面不比后者强多少。如：
He is no richer than Peter.=He is as poor as Peter.
他不比彼得富裕多少.

（2）by far一般用于强调最高级。但也可用于比较级。通常比较级后面，如放在前面，应在两者中间加the.如：
He is taller by far than his brother.
He is by far the taller of the two brothers.

（3）far,by far,a lot,a great deal等副词修饰比较级时，表示前者在某方面远远地超过对方。如：
He works still harder than ever. =He works harder still than ever. 他比以往更加努力学习了。

（4）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。如:
He can't 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?
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.

（5）a little; a bit; rather等程度副词，既可以修饰比较级又可以修饰原级。如：
You’ve done rather well.你做得相当好。
This computer is rather more expensive than that one.这部电脑比那部昂贵一些。
