Hi! this is Kee from BBC Learning English, and today I'm going to tell you the differences between be going to and the present continuous to talk about future plans.
We use be going to to talk about future plans. The plan will probably take place, but it's not a definite plan. If I say: I'm going to meet my friends this weekend. It means I made plans with my friends, but it could mean that we haven't decided where to meet, nor have we decided what time to meet.
On the other hand, we use the present continuous to talk about future plans that are almost definite. If I say: I'm meeting my friends this weekend. It means I made plans with my friends, and we may have decided where to meet and what time to meet. So, this plan is almost definite and it's difficult to cancel.
So remember, the present continuous describes a more definite plan than be going to.
用法总结
1. 语法结构
1) Be going to 结构
Be going to is followed by a bare infinitive verb - a verb with no 'to'. Don't forget to change the 'be' verb to the correct form to agree with the subject pronoun!
“Be going to” 后接动词原形。注意：系动词 “be” 的形式应和主语一致。
I am going to eat something.
She's going to be very angry.
They're going to be late, I think.
2) 现在进行时
The present continuous tense is formed using the auxiliary verb be + (verb)ing. Be careful of state verbs, such as 'know' and 'need', which are only rarely used in the continuous form.
现在进行时的基本结构是：be + 动词-ing。注意：类似 “know（知道）”、“need（需要）” 等状态动词不用于进行时态。
I'm working! What do you want?
He's playing football later.
We're having a party. Would you like to come?
2. 谈论未来计划
1) 用 “be gonig to” 谈论未来计划
Be going to is often used with future plans which will probably take place, but have not been formalised. This means that the exact details, such as what time and where, have not been agreed on.
用 “be going to” 谈论未来计划，可以表示这些计划很可能会发生，但仍未正式确定。这就意味着具体的细节，如计划发生的时间、地点等尚不明确。
I'm going to meet my friends this weekend.
He's going to fix his car later today.
We're probably going to take the train to get there.
2）用现在进行时谈论未来计划
The present continuous is often used with future plans which are almost definite. The details have been decided on and everyone involved knows where they need to be and when.
现在进行时常用来谈论几乎已制定好的未来计划。这类计划的细节已定，每个参与者也都知道计划的时间、地点等。
I'm meeting my friends this weekend.
We're going to the cinema tonight.
She's having dinner with the president of the club tomorrow evening.
