2) be going to 用于一般将来时态中,表示"打算,准备,将要……"。动词be 要随着主语的人称变
化而变化,后面要用动词的原形。
例如:
He is going to walk to school.
I am going to buy a new CD.
They are going to wash the dishes after dinner.
3) go,come,leave这三个词一般不放在be going to 的后面,这三个动词如果要表示将来时,要直接
用be+ going/ coming/ leaving 的形式。
例如:
They are leaving Beijing tonight.
The teacher is coming.
We are going to the Great Wall next Saturday.
