The train leaves at six tomorrow morning.火车明天上午六点开.
When does the bus star?It starts in ten minutes.汽车什么时候开?十分钟后.
2)以here,there等开始的倒装句,表示动作正在进行.例如:
Here comes the bus.= The bus is coming.车来了.
There goes the bell.= The bell is ringing.铃响了.
3)在时间或条件句中.例如:
When Bill comes (不是will come),ask him to wait for me.比尔来后,让他等我.
I'll write to you as soon as I arrive there.我到了那里,就写信给你.
4)在动词hope,take care that,make sure that等的宾语从句中.例如:
I hope they have a nice time next week.我希望他们下星期玩得开心.
Make sure that the windows are closed before you leave the room.离开房间前,务必把窗户关了.
