The cost of living in Glasgow is among the lowest in Britain, _______the quality of life is probably one of the highest.

A.since                  B.when                 C.as               D.while

试题答案

D

解析:

while此处是一个表示转折意义的连词，表示“虽然,但是”。表示the cost of living与the quality of life的对比。since引导原因状语从句，意为“因为”。when引导时间状语从句，表示“当……的时候”。as可以引导时间状语从句也可引导原因状语从句。
