Part II Studying the rules
回顾：现在进行时
现在进行时是英语的一种时态，表示现在进行的动作或存在的状态。现在进行时表示动作发生的时间是“现在”，动作目前的状态是“正在进行中”。
- 表示正在进行的动作
①表示说话的时刻正在进行的动作，常与时间状语now, at the moment等连用。
E.g. I’m sitting on a rock near the river with my friends.
Listen, She is singing an English song.
②表示现在阶段正在进行的动作，而不一定是说话时正在进行的动作，常与today, this week, this term等连用。
E.g. I’m helping my dad on the farm this week.
We are making model planes these days.
- 表示反复性或习惯性的动作
常与副词always, continually等连用，表示说话人的赞扬，厌恶，不满，遗憾等的感情色彩。
E.g. She’s continually making the same mistake. 不满
He is always thinking of others first. 赞扬
学习：现在进行时表将来
- 现在进行时除了用来表示现在正在发生的动作之外，也可以表示不久之后肯定将发生，或按计划或安排将要做的事（常与表将来的时间状语连用）。
观察下列句子的谓语动词：
We’re starting for Shanghai this afternoon.
Our flight is taking off and let’s hurry up; or we will miss it.
The plane is arriving in 10 minutes.
Lilly is walking to school tomorrow.
They are spending their next summer holiday in Guilin.
总结归纳：现在进行时表示将来主要用于按计划或安排将要发生的动作或事件，多用表示位置转移的动词，或是表示交通方式、行程安排的动词。如：
go, arrive, come, get (to), leave, return, start, travel, take, take off, fly, set off, walk, ride, drive, take, spend, buy, marry, see, work, meet, have, play, finish, stay, publish, etc.
- 现在进行时常表最近或较近的将来，句子里常有一个表示未来的时间状语。
E.g. They’re leaving for Hong Kong this afternoon.
What are you doing next Sunday?
I’m not going out for dinner this evening.
- 现在进行时也可在时间、条件或原因状语从句中表示将来。
E.g. When you are passing my house, please drop in.
If they are not doing it, what should I do?
Because the bride is coming, all the people are pleased.
- 表将来的现在进行时有时含有“决心”的意思，多用在否定结构中。
E.g. I’m not waiting any longer. 我决定不再等了。
对比：其他表示将来的形式
- will/shall＋动词原形 表示个人意愿和瞬间决定 *shall只用于第一人称
E.g. I shall do it by my self. （个人意愿）
She will come tomorrow. （瞬间决定）
- be going to＋动词原形 表示说话者的打算和意图（主观）,或者根据某种迹象推测将要发生某事
E.g. We are going to have a meeting today. （打算，计划）
E.g. It is going to rain. （推测）
- be to＋动词原形 表示已经确定日程的将来；或按职责、义务、要求必须去做的事
E.g. The meeting is to be held next week.（确定日程）
- be about to＋动词原形 表示马上就要进行的动作 *不与表示将来的时间状语连用
E.g. He was about to leave when someone called him. （马上发生）
- 一般现在时 表示按时间表将要发生的动作；或“主将从现”
E.g. The train leaves at 7 a.m. tomorrow. （列车时刻表）
