要解決這個(gè)問(wèn)題，我們需要根據(jù)不同的語(yǔ)句類型在做判斷。

1)下列動(dòng)詞：come, go, arrive, leave, start, begin, return的一般現(xiàn)在時(shí)表將來(lái)。這主要用來(lái)表示在時(shí)間上已確定或安排好的事情。

The train leaves at six tomorrow morning.

When does the bus star? It stars in ten minutes.

2)倒裝句，表示動(dòng)作正在進(jìn)行，如：

Here comes the bus. = The bus is coming.

There goes the bell. = The bell is ringing.

3)在時(shí)間或條件句中。

When Bill comes (不是will come), ask him to wait for me.

I'll write to you as soon as I arrive there.

4)在動(dòng)詞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.
