The next train will in five hours对in five hours提问

问题描述:

The next train will in five hours对in five hours提问

Managehong的答案正确。

How soon will the next train arrive?

应该是:
How soon will the next train arrive?
你好象少打了个动词arrive
下趟火车多久能到?

答案为:How soon will the next train (arrive)?
”in+时间“的结构为对时间段即频率提问,用how soon
