核心问题
The time (for you) to go is July.
the time 与充当其定语的 to go 在语义上存在着状语关系,为什么在动词不定式中不用任何介词?
词典解答
如果写成 the time at which 或 the time when, the time that 就显得太正式, 因此 the time to go 是最常见的形式, 可以把它看成是一种省略形式。具有这种用法的名词还有 moment, instant, minute, place, way 等(参见 infinitive )。例如:
the place to live (sit) the way to do it the time to arrive is... [“at which you should arrive”] at a time 见 at a time
