你好,
正確選項(xiàng)是： A
第一個(gè)空 填 過去分詞 changed ,
found everything changed 發(fā)現(xiàn)一切都變了
第二個(gè)空填 過去完成時(shí)
while 前后時(shí)態(tài)一致,因?yàn)?we had been away 是過去完成時(shí),所以前面不能用現(xiàn)在完成時(shí) has happened .
When we returned from our holidays,we found everything______.What______while we had been away?
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
為什么第二空不能選has happened
A.changed；had happened B.changing；happened；
C.had changed；has happened D.was changing；happened
為什么第二空不能選has happened
