Module 1 Grammar

I. be going to 的用法

be going to结构表示按计划、打算去做某事，表示人的主管意图，有时还可表示预测有迹象要发生某事。如：

. How long is your aunt going to stay in China for a visit?

(计划、打算)

. Look at the clouds. It’s going to rain.

(有迹象要发生)

. George is putting on weight. He is going to be quite fat.

(预测)

II. be going to与will的区别

. will表示说话人认为、相信要发生的事, 不含具体时间, 可以指遥远的将来; be going to 表示按计划、打算即将发生的事。

. 二者都可以表示“意图” 。但是表示事先考虑的事情用be going to, 否则用will。如: I am not going to / won’t tell him about it.

--This is a very heavy box.

--I’ll help you to carry it.

. be going to 可以用在条件句中表示 将来, will则不行。 如:

If you are going to attend the party, you’d better leave now.
