题目

They stopped ______ and ______ out to play when they ______ the bell ring or rest.
They stopped ___A___ and ______ out to play when they ______ the bell ring or rest.
A.working; went; heard
第二个空为什么是went?

答案

stop doing sth,所以是working.后面连接所用的went 是根据前面的and 体现的,and 连接两个并列短语,时态应该一致,根据前面是用的过去式,所以应该用went
