Question

【题目】Traveling abroad _____________ to rich tourists and wealthy business people decades ago.

A. is limitedB. has been limited

C. was limitedD. had been limited

Answer 1

【答案】C

【解析】

考查动词时态和语态。句意：十几年前出国旅游还仅限于有钱的游客和富有的商人。根据时间状语decades ago可知应用一般过去时，主语Traveling abroad与谓语动词limit构成被动关系，故用一般过去时的被动，选C。
