一、一般将来时
1．用be doing表示将来,：主要意义是表示按计划、安排即将发生的动作。它常表最近或较近的将来，所用动词多是转移动词。如go，come，leave，arrive，move等
(1) I’m going. 我要走了。 (2) When are you starting? 你什么时候动身？ 表将来的现在进行时除用于转移动词外，亦可用于某些非转移动词。如：
(1) I’m meeting you after class. 课后我找你。
(2) What are you doing next Sunday? 下星期你打算干什么？
2．用be going to do表示将来：一是表示“意图”，即打算在最近的将来或将来进行某事。 e.g.: Are you going to post that letter?
How long is he going to stay here?
另一意义是表示“预见”，即现在已有迹象表明将要发生或即将发生某种情况。
e.g.: It’s going to rain.
基本结构：
She will come to have class tomorrow. Will she come to have class tomorrow? She won’t come to have class tomorrow.What will she do tomorrow?

Anything用于否定句和疑问句。 Is there anything in that box?
可以用于肯定句中，无论什么： I want something to eat,anything will do.
