过去进行的重要用法：
1. 表示临时性
即表示在过去短期内正在进行的动作或存在的临时情况，这种情况通常不会长期如此。如：
It happened while I was living in Paris last year. 这件事发生于去年我住在巴黎的时候。
2. 表示计划
即表示为过去的将来计划或安排好的活动。这类用法在没有明确上下文的情况下，通常会连用一个表示将来时间的状语。如：
He said that his sister was getting married next December. 他说他妹妹12月结婚。
用arrive, come, go, leave, take off等动词的现在进行时描写行程安排，也通常有含有将来意义。如：
He said he was leaving for home in a day or two. 他说他一两天之内就动身回家了。
She knew the plane was taking off in five minutes. 她知道五分钟后飞机就要起飞了。
现在进行时的用法：
1. 表示正在进行
现在进行时除表示说话时正在进行的动作之外，还可表示在短期内临时进行的动作或存在的情况，这种情况通常不会长期如此，并且在说话时刻也不一定正在进行。如：
Don’t take that ladder away. Your father’s using it. 别把梯子拿起，你父亲在用哩。
The professor is typing his own letters while his secretary is ill. 秘书生病时，教授自己打他的信。
2. 表示短期内在进行
表示在短期内正在进行的动作或存在的情况，这种情况通常不会长期如此。如：
Her car has broken down. She’s going to work by bike. 她的汽车坏了，骑自行车上班。
The professor is typing his own letters while his secretary is ill. 秘书生病时，教授自己打他的信。
这种情况在说话时不一定在发生。如：
Don’t take that ladder away. Your father’s using it. 别把梯子拿走，你父亲在用哩。(说话时不一定正在用)
表示将来的常用非时态方式：
1. 用现在进行时表示将来：主要表示按规定或时间预计要发生的事。如：
The students are leaving on Sunday. 学生们星期日出发。
We’re having a party next week. 我们下星期将开一个晚会。
2. 用一般现在时表示将来：表示按规定或时间预计要发生的事。如：
We have a holiday tomorrow. 我们明天放假。
The train leaves at 10:04 this evening. 火车今晚10:04分开。
