Bob tried to sweet-talk his mother into letting him go out. But when he saw his sweet talk________, he lost his temper.
A.hadn’t worked
B.wasn’t working
C.isn’t working
D.doesn’t work
答案
答案:B
题目分析:考查时态:句意:鲍勃试图用花言巧语骗诱妈妈让她出去,但是当他看见他的花言巧语没有用的时候,他发脾气了。从前面的句子:Bob tried to sweet-talk his mother into letting him go out可知是发生在过去的事情,排除CD,因为是先花言巧语骗诱妈妈,然后才发现不管用,所以不是过去完成时,用过去进行时,表示当时的情况,选B。
