英语句子改错1.I'm sorry I can't go in because I lost the key to th

1.have lost(已经丢失).顺便回答楼上的,the key to the door没错,因为一把钥匙对一把门,不象the student of Class One,用to作介词的例子还有:the answer to the question,the solution to the problem等,都是一一对应的关系.
2.Had you had(two hours ago修饰过去,应用过去完成式)
3.have left(for或since前的时态用现在完成式)
4.has been dead或died(died是瞬间动词,应做改动)
5.have you joined 改have you been in(join是瞬间动词,提问how long应用be in,意思是一样的)
6.heard from(去掉the letter)(hear from 本身就是收到...来信的意思,the letter是多余)
7.have you been(原因同第5问)
8.I am late或did't see(haven't seen对现在产生影响,所以用一般现在式,或者不用现在完成,就用过去式)

1 of the door
2 did you have
3 about
4 died(不应该有完成时的词)
5 joined in
6 the letter
7 have you been
8 didn't see
