Question

以下两道题不知是选一般过去时还是过去完成时，为什么？紧急寻求高手帮忙，非常感谢！！

（1）They finished the work earlier than they _____.
A has expected B. had expected C. expected D. would expected
（2）The little girl had to make a living herself because her parents _____.
A died B. have died C. had died D. had dead

Answer 1

第1小问是B因为前面是过去式而又是在完成工作之前所以应该是过去的过去所以选B

第2问是A因为小女孩的父母死了是事实所以用一般过去时

Answer 2

B A 因为都是在过去某个时间之前已经完成的，并且句中有过去的时间作对照。
