问题描述:
When we returned from our holidays,we found everything______.What______while we had been away?
A.changed;had happened B.changing;happened;
C.had changed;has happened D.was changing;happened
为什么第二空不能选has happened
答
你好,
正确选项是: A
第一个空 填 过去分词 changed ,
found everything changed 发现一切都变了
第二个空填 过去完成时
while 前后时态一致,因为 we had been away 是过去完成时,所以前面不能用现在完成时 has happened .
