Question

【题目】 Not until recently ______the development of tourist-related activities in the rural areas.

A. they had encouraged B. had they encouraged

C. did they encourage D. they encouraged

Answer 1

【答案】C

【解析】

试题分析：考查部分倒装。当not until所引导的时间状语放在句首的时候，主句要使用部分倒装句。排除AD项，B项为过去完成时，上下文中并没有体现出过去的过去的时间。句意：直到最近他们才鼓励在农村地区开展与旅游业有关的活动。故C正确。
