Question

Things have changed quickly over the past decade and life in the country is much better than ___used to be．

A．that	B．what
C．it	D．one

Answer 1

C

试题分析：句意：在过去的几十年情况已经发生了很大的变化，乡村的生活比过去好多了。这里需要代词指代life in the country，属于同类同物，that是特指前面的可数名词单数或不可数名词，而且后面有后置定语，what引导得失宾语从句，这里缺少主语，one是泛指可数名词单数，所以选C。
