Question

l'tell you later 这个later为什么放最后呢 不是修饰动词的么?
in how many minutes do they carry messages from one garage to the other和at what time do you finish work every day 为什么开头会有介词 请问这是什么语法

Answer 1

later 是时间状语,修饰整个句子.
这两句疑问句开头有介词不奇怪.
in how many minutes do they carry messages from one garage to the other在多少时间内他们把信息从一个车库传到另一个车库?(in表示在.内)
at what time do you finish work every day
你每天几点完成工作?(at what time意为在几点钟)
另外再举个例子:
For what reason did you go there?你为什么要去那里?
For whom do you work?你为谁工作?
