题目内容
【题目】We sell a lot of products offshore and the opportunity to open up markets in regions ________ we don't currently sell a lot to is a great one.
A. where B. that
C. what D. when
【答案】B
【解析】考查定语从句。分析句子成分,主句the opportunity is a great one,先行词是regions,定语从句we don’t currently sell a lot to中缺少to的宾语,所以只能用that或者which,故选B。
