问题补充:
The way of life he was used to when he came to study in America.
A. change
B. changed
C. changing
D. being changed
答案:
A. change
B. changed
C. changing
D. being changed
解析:考查时态:分析句子可知,由于he was used to为定语从句,修饰the way of life,因此句子缺少谓语,时间状语从句是when he came to study in America.所以用过去式,句意:当他到美国学习的时候他习惯的生活变了。故选B
