Hi! this is Kee from BBC Learning English, and today Im 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 its not a definite plan. If I say: Im going to meet my friends this weekend. It means I made plans with my friends, but it could mean that we havent decided wher 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: Im meeting my friends this weekend. It means I made plans with my friends, and we may have decided wher to meet and what time to meet. So, this plan is almost definite and its difficult to cancel.
So remember, the present continuous describes a more definite plan than be going to.
使用方法概要
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. Dont 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.
Shes going to be very angry.
Theyre going to be late, I think.
2) 目前进行时
The present continuous tense is formed using the auxiliary verb be + ing. Be careful of state verbs, such as know and need, which are only rarely used in the continuous form.
目前进行时的基本结构是：be + 动词-ing。注意：类似 “know（了解）”、“need（需要）” 等状况动词不需要于进行时态。
Im working! What do you want?
Hes playing football later.
Were havin a party. Would you like to come?
2. 谈论将来计划
1) 用 “be gonig to” 谈论将来计划
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 wher, have not been agreed on.
用 “be going to” 谈论将来计划，可以表示这类计划非常或许会发生，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、地址等尚不清楚。
Im going to meet my friends this weekend.
Hes going to fix his car later today.
Were probably going to take the train to get there.
2）用目前进行时谈论将来计划
The present continuous is often used with future plans which are almost definite. The details have been decided on and everyone involved knows wher they need to be and when.
目前进行时常用来谈论几乎已拟定好的将来计划。这种计划的细节已定，每一个参与者也都了解计划的时间、地址等。
Im meeting my friends this weekend.
Were going to the cinema tonight.
Shes havin dinner with the president of the club tomorrow evening.
