答案和解析
A. had met B. have met
答案是B 为什么不能选A?
如果选A, 必须要发生在过去的过去,可是文中找不到过去,更别提过去的过去了

c.to meet D.to have met
答案是C 为什么不选D?
agree to have done=have agreed to do
我们已经同意,因为后面有完成时 has not 作对比

why not _____ by plane for a change?
B.trying to go D.try going
why not 其实加什么都可以
只是try to do=努力做
try doing=尝试做

肯定是尝试做 飞机
