A.to stop providing B.stopped providing

【提问】初中英语选择~Since June 1st last year,all the supermarkets have ( )tree plastic bags.A.to stop providing B.stopped providing
B
stop doing
前面又since 时间,动词要用现在完成时
而A选项加了to ,have to do ,就不是完成时态了

选B,这里应该用现在完成时代

B
have to do sth 意思是不得不做某事
have stopped doing sth 意思是已经停止做。。。
这句话的意思是自从去年七月一日,各个超市就已经停止供应免费一次性方便袋
