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.重点语法归纳：

What do you want to be when you grow up? I want to be an engineer.

How are you going to do that? I'm going to study math really hard.

Where are you going to work? I'm going to move to Shanghai.
