「Be going to」 結構和現在進行時都可以用來談論未來的計畫和安排，但在使用時要注意它們的區別：「be going to」 只能指一個大致的安排、打算，而現在進行時可以突出未來的計畫已經確定，細節已定。看視頻，學習如何使用 「be going to」 和現在進行時來談論未來的計畫。
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.
1) Be going to 結構
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」 後接動詞原形。注意：系動詞 「be」 的形式應和主語一致。
- I am going to eat something.
- She‘s going to be very angry.
- They‘re going to be late, I think.
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.
現在進行時的基本結構是：be + 動詞-ing。注意：類似 「know（知道）」、「need（需要）」 等狀態動詞不用於進行時態。
- I‘m working! What do you want?
- He‘s playing football later.
- We‘re having a party. Would you like to come?
1) 用 「be gonig to」 談論未來計畫
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」 談論未來計畫，可以表示這些計畫很可能會發生，但仍未正式確定。這就意味著具體的細節，如計畫發生的時間、地點等尚不明確。
- 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.
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.
- 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.
