问题描述：
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?
答
to be 不可以不用，因为这是由句子结构决定的。
to be in time for the flight在句子中是目的状语。如果缺少 to be，则不成句子。
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,!
