Question

when is the next train from here to London？（six hours）
回答the next train from here to London is in six hours' time这句话为什么没有加will 还有为什么要加个be动词is？说成the next train will from here to london in six hours' time不行吗？
这个题目是说用括号中表示时间的短语和time来回答问题
像when will she go back home（a week）
回答 she will go back home in a week‘s time

Answer 1

1、when is the next train from here to London？一般现在时态表示一种常态行为， the next train from here to London中train到站时间早有安排，所以没必要用将来时态
2、the next train will from here to london in six hours' time纯粹汉语式译法，will后加动词原形。
