问题描述：
the next train is due in five minutes.the next train is due to arrive five minutes later
为什么一个有to一个没有
答
意思不一样,用法不同！due本身就是形容词，有预定，预计的，约定，预期的意思。在句中做表语。如：The train is due in five minutes.火车预定在5分钟后到达
另外due to是副词，表原因 。
Eg:Due to your carelessness, it doesn't work now.
It doesn't work due to your carelessness.
be due to也算是固定结构 意思是由于,因为
Eg:The failure of the scheme was due to bad management.
各有各的用法！
答
1.is due + 时间,表示（这件事）在预计的时间内会（发生）
在这句话里就是下列车预计5分钟后（会到达）
2.is due (to arrive) + 时间
不定式 to arrive 在这里做 主语（the next train)的补足语
这句话 可翻译成 下列（到达的）车 预计会在 5分钟后.
