这种用法最好通过实例来了解。设想一个班的学生上午9点半在做什么，然后可以这样表达：

　　Now they are sitting in their classroom．They are listening to a tape． This time tomorrow they will be sitting in the cinema．They will be watching a film．On Saturday there is no class．So on Saturday they will not be sitting in the classroom．They will be doing other things．Bill will be playing tennis． Ann will be shopping．George will still be having breakfast．

　　现在他们正坐在教室里。他们在听录音。明天这个时候他们会坐在电影院里看电影。星期六没有课。因此，星期六这时候他们不在教室里。他们会做别的事情。比尔会在打网球，安会去买东西，乔治会还在吃早饭。

　　进行时态也可以和一般现在时连用：

　　Peter has been invited to dinner with Ann and Tom． He was asked to come at eight but tells another friend that he intends to arrive at seven．The friend tries to dissuade him，‘When you arrive they’ll still be cookingthe meal！’

　　彼得应邀与安和汤姆一起吃饭。他们要彼得8点到，但彼得却告诉另一位朋友说他自己想在7点到。那位朋友劝阻他说：“你到的时候，他们还在做饭呢！”
