哪些后面要用一般现在时代替将来时

Question

说一些引导词吧

Answer 1

1、在主从复合句中，当主句为一边将来时，时间状语从句和条件状语从句中用一般现在时代替将来时，
When he comes (不是will come), ask him to wait for me here.
I'll write to you as soon as I arrive there.
2、表示按规定、计划或时间表将要发生的事。
He starts next week. 他下个星期出发。
We leave very soon. 我们很快就离开。
The train starts at 10 o'clock in the morning.
火车将在早上10点开出。
这类用法限于表示“移动”的动词：go去，come来，leave离开，start出发，begin开始，
下列动词：come, go, arrive, leave, start, begin, return,live,fly的一般现在时表将来。这主要用来表示在时间上已确定或安排好的事情。
The train leaves at six tomorrow morning.
When does the bus start? It starts in ten minutes.
在动词hope, take care that, make sure that等后。
I hope they have a nice time next week.
Make sure that the windows are closed before you leave the room.
