选择题
The mother along with her children _______ in the supermarket when the explosion happened.
A.was shopping
B.were shopping
C.have been shopping
D.had shopped
答案
A
题目分析:考查主谓一致和固定句型。固定句型be doing sth when…正在做某事在这时发生了意料之外的事情;故使用进行时,另外本题的主语是The mother along with her children,谓语动词应该与the mother保持一致,使用单数形式。故A正确。
点评:。固定句型be doing sth when…正在做某事在这时发生了意料之外的事情;当名词和along with…做主语的时候,谓语动词与第一个名词保持一致。
