一、课文原文
Lesson 85 Never too old to learn
I have just received a letter from my old school informing me that my former headmaster, Mr. Stuart Page, will be retiring next week. Pupils of the school, old and new, will be sending him a present to mark the occasion. All those who have contributed towards the gift will sign their names in a large album which will be sent to the headmaster's home. We shall all remember Mr. Page for his patience and understanding and for the kindly encouragement he gave us when we went so unwillingly to school. A great many former pupils will be attending a farewell dinner in his honour next Thursday. It is a curious coincidence that the day before his retirement, Mr. Page will have been teaching for a total of forty years. After he has retired, he will devote himself to gardening. For him, this will be an entirely new hobby. But this does not matter, for, as he has often remarked, one is never too old to learn.

本课主要是复习第13课、第37课和第61课所学的将来时态的用法。
（一）第13课
本课侧重学习的是将来进行时的基本用法，即表示将来某个时刻或时段会正在进行的动作，其基本结构为：
sb. will be doing sth.

其疑问句只要把will提到主语前面即可，如：
- Will she be visiting you next Monday?
- Yes, she will.
- No, she won't.
When will she being visiting you?
将来进行时常见的标志词有：
时刻+将来时间，如：at five p.m. tomorrow。
