一般将来时五种基本句式的区别
一般将来时
一般将来时表示将来某个时间要发生的动作,事情或存在的状态,也表示将来经常或反复发生的动作或事情.
1)will/shall+动词原形 shall用于第一人称,常被will 所代替.will 在陈述句中用于各人称,在征求意见时常用于第二人称.will not=won't shall not=shan't例如:
Which paragraph shall I read first?我先读哪一段呢?
Will you be at home at seven this evening?今晚七点回家好吗?
2) be going to +不定式,表示将来.
a.主语的意图,即将做某事.例如:What are you going to do tomorrow?明天打算作什么呢?
b.计划,安排要发生的事.例如:The play is going to be produced next month.这出戏下月开播.
c.有迹象要发生的事.例如:Look at the dark clouds,there is going to be a storm.看那乌云,快要下雨了.
3) be +不定式表将来,按计划或正式安排将发生的事.例如:
We are to discuss the report next Saturday.我们下星期六讨论这份报告.
4) be about to +不定式,意为马上做某事.例如:
He is about to leave for Beijing.他马上要去北京.
注意:be about to do 不能与tomorrow,next week 等表示明确将来时的时间状语连用.
Notice:be to和be going to
be to 表示客观安排或受人指示而做某事,be going to 表示主观的打算或计划.例如:
I am to play football tomorrow afternoon.明天下午我去踢球.(客观安排)
I'm going to play football tomorrow afternoon.明天下午我想去踢球.(主观安排)
5.现在进行时表将来时
下列动词的现在进行时表示将来时
go.come.fly.leave.start.begin.finish.end.arrive and so on.
she is leaving for Wuhan tomorrow.
6.一般现在时表将来
1)下列动词come,go,arrive,leave,start,begin,return的一般现在时可以表示将来,主要用来表示在时间上已确定或安排好的事情.例如:
The train leaves at six tomorrow morning.火车明天上午六点开.
When does the bus star?It stars 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:
