您好!in the five years' time 和 in five years' time 有何区别?分别举例!

Answer 1

一、关于介词 in 表示时间
1.in the five years' time 指的是“在已知的曾经存在的五年中”,对现在而言业已过去.由于表示一个有起点有终点的时间段,所以同时还暗指终点这一时间点,属于过去的过去,因此一般要与过去完成时态连用,如本句：
In the five years' time,they had worked on the project.在那五年中,他们一直都在致力于该计划/工程
2.如果要表示与说话时衔接的刚过去的时间,则需要用 in the past/last ...s' time 或者 in the past ...s'.这种情况要与现在完成时态连用如：
They have worked on the project in the past/last five years （或 five years' time).在刚过去的这五年中,他们一直都致力于该计划/工程.
3.in five years' time 或 in five years,则不同,这是表示未来的五年以后,需要与将来时态连用,如：
I'll see you again in five days (或in five days' time ).五天后我再见你.
