1.There had been someone in our room just now,because I_____a burning cigarette end on the floor when we opened the front door.(notice) 为什么不能用was noticing?when不是说当。。。的时候吗?
2.That was really a splendid evening.It's years since I have enjoyed myself so much.哪里错了?应怎么改?为什么呢?
3.she____her hairstyle in her hometown before she came to chongqing for a better job.
a.would change b.has changed c.changed d. was changing
为什么是c呢?她change不是在她find job之前吗?不是要用过去完成时态吗?
谢谢帮助..!
