英语语法将来时怎么用
这个问题有点模糊.
英语中时间轴上只有过去,现在和将来.将来时都发生在将来的时间里,
有一般描述,计划,进行和已经完成三种.
那我来简单说一下将来时的最常见的三种时态吧.
1 一般将来时
1) shall用于第一人称,常被will 所代替.
will 在陈述句中用于各人称,在争求意见时常用于第二人称.
Which paragraph shall I read first.
Will you be at home at seven this evening?
2) be going +不定式,表示将来.
a.主语的意图,即将做某事.
What are you going to do tomorrow?
b.计划,安排要发生的事.
The play is going to be produced next month.
c.有迹象要发生的事
Look at the dark clouds,there is going to be a storm.
3) be +不定式表将来,按计划或正式安排将发生的事.
We are to discuss the report next Saturday.
4) be about +不定式,意为马上做某事.
He is about to leave for Beijing.I was about to go out when it started to rain.
注意：be about to 不能与tomorrow,next week 等表示明确将来时的时间状语连用.
be going to / will
用于条件句时,be going to 表将来
will 表意愿
If you are going to make a journey,you'd better get ready for it as soon as possible.
Now if you will take off your clothes,we will fit the new clothes on you in front of the mirror.
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.
I am to play football tomorrow afternoon.(客观安排)
I'm going to play football tomorrow afternoon.(主观安排)
2 将来进行时
1) 概念：表示将来某时进行的状态或动作,或按预测将来会发生的事情.
She'll be coming soon.
I'll be meeting him sometime in the future.
注意：将来进行时不用于表示"意志",不能说 I'll be having a talk with her.
2）常用的时间状语
Soon,tomorrow,this evening,on Sunday,by this time,tomorrow,in two days,tomorrow evening
By this time tomorrow,I'll be lying on the beach.
3 将来完成时
1) 构成will have done
2) 概念
a.状态完成：表示某事继续到将来某一时为止一直有的状态.
b.动作完成：表示将来某一时或另一个将来的动作之前,已经完成的动作或一获得的经验.
They will have been married for 20 years by then.
You will have reached Shanghai by this time tomorrow.
