有一读者问： 下面一段文字中为什么用将来进行时？
(1)The Greenwood Boys are a group of popular singers. At present, they are visiting all parts of the country. They will be arriving here tomorrow. They will be coming by train and most of young people in the town will be meeting them at the station. Tomorrow evening they will be singing at the Worker's Club...
上述引文中最后三句所用的将来进行时是这一时态最典型的一种用法，即表示已安排好的或预告将来要发生的事。这种用法一般须有一将来某一时间，如上述引文中的第三句和第五句，再如：
(2)Professor Craig will be giving a lecture on English poetry tomorrow afternoon.
(3)We'll be living in Shanghai next year.
如果上下文已清楚地表明将来时间，则可省去不表，如上述引文中的第四句，再如：
(4)I'll be waiting for you. （对话双方皆知所指的将来时间）
(5)Will you be eating your meals in the hotel? （指对方在旅馆居住期间）
