麻烦逐项分析，谢谢^o^

I won't go to see the football match tonight,because I _____ my ticket.(B)
A didn't have B lost C have lost D will lost.
选B 丢了票
如果A，则应该是I did not have my ticket with me. or I do not kave a ticket.
如果是C，票只可以丢一次，不可以用have
D是将来丢，不可能。
Old people must _____ .(D)
A be spoken politely B speak polite
C speak to polite D be spoken to politely
选D 对人讲话是speak to sb. 如果变成主动句，You must speak to old people politely. 就清楚啦。
A没有TO
B动词不对
C动词不对，
不过这类句子还是主动句好用的。
