比较：
Be going to
我们过去打算（我们已经决定）：
我们要吃饭了。
尼尔打算买一件新毛衣。
我明天要去看望我叔叔。
将
我们使用will即时做出决定（在发言时做出决定）：
我知道。我们将举行一个聚会。是的，好主意。
天气很冷。我会关上窗户。（不是很冷。我关上窗户。）
比较:
将要做某事
我们用be going to来表示基于当前情况(我们能看到将要发生的事情)的预测:
我们用will来预测(我们认为会发生的事情):
我们也会在要约和承诺中使用“意愿”：我会为你邮寄那封信。
所以我们可以用两种形式来预测:
We're going to win the match.
(We're playing really well.)
We'll win the match.
(We've got the best team.)
我们经常用be going to表示意图，will表示细节和评论:
我要和几个朋友一起吃饭。我们大概有十个人。哦，那太好了。
我们经常用will和I'm sure, I think, I expect和probably连用:
We often use will with I'm sure, I think, I expect and probably:
I'm sure it'll be all right.
I expect we'll lose the match.
I think we'll get there on time.
I'll probably have a meal.
Look at this question and answer:
Melvyn: Are you doing anything this evening?
Bill: Yes, I'm going to the ice hockey match. The Tigers are playing the Kings. I bought my ticket yesterday.
We use the present continuous for what someone has arranged to do. Here Bill has arranged to go to the match. (He has bought a ticket.)
I'm meeting Ann at six o'dlock.
Phil is coming round later on.
They're playing ice hockey tonight.
Judy is going to Malta next week.
The present continuous and be going to have similar meanings:
We're having a party soon. (We have made the arrangements.)
We're going to have a party soon. (We have decided to have one.)
Present simple for a timetable
Polly: What time does your train leave tomorrow?
Mike: Ten twenty-five. And it arrives in Gloucester at eleven ten.
We can use the present simple for the future when it is part of a timetable:
The train leaves at ten twenty-five tomorrow morning.
The match starts at seven thirty.
Next Friday is the thirteenth.
但是我们不使用一般现时来表示意图和决定
:not :
I buy my ticket tomorrow- or I give you a lift this evening。
Present simple after when, before etc.
We use the present simple for the future after ：when, as, while, before, after, as soon as and until:
We'll have coffee when the visitors get here.
I must get to the bank before it closes.
As soon as you hear any news, will you let me know?
Both actions are in the future. But we do not use will after when, as etc.
NOT We'll have coffee when the vistors will get here.
The same thing happens after if, who/ which and that:
If you see Elaine, can you give her a message?
The people who arrive early will get the best seats.
I'll make sure (that) everything is ready.
