题目内容
【题目】 Since several years ago, many supermarkets in China have _______ free plastic (塑料的) bags.
A. to stop providing B. to stop to offer
C. stopped to provide D. stopped offering
【答案】D
【解析】
试题分析:句意:自几年前以来,在中国的许多超市都停止了提供免费塑料袋。根据Since several years ago,可知该用现在完成时,而现在完成时是由“have/has + 实意动词的过去分词”构成的。stop doing sth停止正在做的事。所以选D。
