Question

【题目】—What do you think made Mary upset?
—___________ her new bicycle.
A.As she lost
B.Losing
C.Lost
D.Because of losing

Answer 1

【答案】B
【解析】考查动名词。句意：——你认为什么使玛丽那么不安？——丢了她的新自行车。这里第一句中的do you think是插入语，what在句中作主语；第二句是省略句，完整的是Losing her new bicycle made her new bicycle.所以选项必须能够做主语，A是状语从句，C是过去分词，不能做主语； D是原因状语，故选B。
