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.
