答案
32,C. until
这是not.until句型,seldom含有否定(not)的意思.
26.C. one
one指代前文提到的同类事物,而it只能特指前文提到的具体的某一个事物.
27.C. must
must have done是对过去事情的肯定推测,She looks very happy是选它的依据;might have done 是对过去事情的十分不肯定的推测
38.C. much more than
money不能与many为伍,选项A. not so many as 和B. as many as 首先排除; D. much less than与题意不符.
34.C. where
句子的骨干是个表语从句,主语是development,系动词是is,表语是(where)the key to better education lies.其中表语又是个状语从句,主语是the key,谓语是lies,状语就是where.
