请问这道英语选择题应该选哪一个？为什么？

Question

It was _______ we had hoped.
A.more a success than
B.a success more than
C as much of a success as
D a success as much as
为什么不能选D，该选什么?

Answer 1

应该是考查形容词比较等级和比较状语从句.
比较等级结构包括同级比较（as.as.）和差级比较（more than）.由于后面加的是从句,因此,本题已经和比较状语从句相关,但重点还是在理解同级比较和差级比较.
本题的句意为：这比我们原来希望的要成功得多（或和我们原希望的一样成功）.
选项A,more是用来构成比较级的副词,其后必须加形容词或副词.如果单独使用,more本身就是形容词,中间不能再加其它东西,也就是说,可以这样It was more than we had hoped.
如果加一个of就对了,因为,of+名词＝形容词.
比如：This method is of great importance==This method is very important.（这就是你问题补充的回答）
选项B,是A more than B结构,两个部分都应该是名词.或写为more A than B
如：My old man is more a friend than a father或 My old man is more than a father,he is also my good friend.意思是我老爸不仅仅是个父亲,更是我的朋友.
选项C,as .as 中间应为形容词或副词的原级.而of+名词＝形容词
选项D,应说成 as much success as或as much of a success as
