be going to和will

【辨析】

1. 两者都用来表示意图，但be going to强调"打算和意向"，表示要做某事的主观意图，而will强调"意愿、承诺和提议"。如：

　We are going to have a party this evening.

　Will you go to Hong Kong Disneyland Park with me?

2. be going to表示事先经过考虑或事先做好安排，而will则没有经过事先考虑，是说话瞬间做出的突然决定。如：

　- Why are you putting on those old clothes?

　- I'm going to decorate the room.

　What shall I do tomorrow? I don't know! Maybe I'll read some books.

3. 预测将要发生的事情时，be going to强调从目前的证据或迹象做出推测，表明可能发生某事，而will的预测是依据观点或信念。如：

　Look at the dark clouds. There is going to be a storm.

　The sun will rise tomorrow.

4. 表示将来时间时，be going to可用于条件状语从句中，will则不能；但will表示"意愿"时可以用在条件句中。如：

If you are going to play basketball this evening, you'd better finish your homework in advance.

　If you will give him a hand, I'll tell you what happened.
