I must go to the airport to be in time for the flight.I must go t_英语解答

I must go to the airport to be in time for the flight.
I must go to the airport to be in time for the flight.
为什么这句要用 to be 可不可以不用,直接I must go to the airport in time for the flight.
用和不用有什么区别?

解答

这个因为是两个动词连接在一起所以中间要用to,而to be 不能减少如果减少这个句子就不成立
答题实属不易,请楼主谅解,!
