Are you going to see your friends this weekend? Yes ,I am. / No, I'm not.

④特殊疑问句： 疑问词 + be + 主语 + going to + 动词原形 + 其他？

What is he going to do this weekend?

When are you going to see your friends?

2) 如果表示计划去某地，可直接用 be going to + 地点

We are going to Beijing for a holiday.

3) 表示位置移动的动词，如go , come, leave 等常用进行时表示将来。

The bus is coming.

My aunt is leaving for Beijing next week.

4) be going to 与 will 的区别：

① 对未来事情的预测用" will + 动词原形"表达，will 没有人称和数的变化，变否定句要在will 后面加not, 也可用will 后面加 not,或者缩略式won't, 变一般疑问句将will 提至 句首。

Will planes be large in the future?

Yes, they will. / No, they won't.

②will 常表示说话人相信或希望要发生的事情，而be going to 指某事肯定发生，常表示事情很快就要发生。

I believe Lucy will be a great doctor.

③ 陈述将来的某个事实用will.

I will ten years old next year.

④表示现在巨大将来要做的事情用 will.

I'm tired I will go to bed.

⑤ 表示意愿用will.

I'll tell you the truth.

⑥ 表示计划、打算要做的事情用 be going to, 而不用 will.
