I have three more books than you (do).
I have three books more than you do.
第二种写法,也见到国外朋友们用过.more than 这里,还是 more than 词组那个意思么?多于.
还是说,只是 more ,加上介词 than 刚好用在了一起,不少原来组合的那个意思.

问题解答:

我来补答
1.more than 20 years.more 这里是是副词还是adj.
1) more 有三种词性,在脱离句子的情况下,不易判定其词性所属,如:
* 形容词:
Today you can see something more than before.如今你可以比过去看到更多的东西.(more 后置修饰 something)
* 副词:
Chinese people are much more hardworking than 20 yeas ago中国人民比20年前更加勤劳.(much more 后置修饰形容词 hardworking)
* 名词:
She has more than ever 她拥有的比以往任何时候都多..(more 是 has 的宾语)
2) 如果把 more than 孤立起来考虑,可以表示不同的意思,由于充当的语法成分不同.所表现出来的词性也不同,如:
* 表示“大于/多于”
--I have lived here more than 20 years.我已经在这里生活了20多年.(more 充当动词 lived 的状语.因此是副词)
* 表示“不仅仅/不只是”
--He is more than a scholar.他不只是个学者.(more 作表语,指代与 scholar 同类的名词,因此是不定代词)
2.下面两句话的语法结构不同——
1)I have three more books than you (do).
three more books 是 have 的宾语,than you do 是have的比较状语,意思是“我比你多三本书”.
同理——
She has four fewer books than I do 的结构也相同..——我比你少三本书
2)I have three books more than you do.,
three books是 have 的宾语,more than you do 是形容词短语作后置定语,意思是“我有比你多出来的三本书”.
同理——
She has four books fewer than I do 也是如此.——他有比我少出来的四本书.
