选择题
It’s time he _________ piano. Don’t you think he has wasted too much time online?
A.stopped to take up
B.stops taking up
C.stopped to leave alone
D.stops leaving alone
答案
答案:A
考查句型:It’s time (that)后用一般过去式或should do, should 不能省略,意为:做什么的时间到了,句意:他停下来弹钢琴的时间到了。难道你不相信他在网上已经浪费了太多的时间吗?stop to do 停下来去做某事,stop doing停止做某事,所以选A。
