将来进行时-想象未来

典型用法：将来某一特定时刻正在持续的事
Don't telephone me after eight tomorrow-I'll be having a meeting.
Wait until seven o'clock so that they won't still be eating.
By this time nest year, I will be writing my thesis.
口语用法：将来计划好的事
Professor Smith will be giving a lecture on American literature tomorrow evening.
Be doing也可以表示计划好的事，因此，表示将来安排好的事情，两种时态可以换用。
He is taking/will be taking a makeup test week.
I'm taking her to the Forbidden City in the morning, and later I'll be taking her to the Great Wall.
不过，二者还是有下列两点不同：
1/现在进行时只表示最近的将来；而将来进行时既可以表示最近的将来，也可表示较远的将来。
I am meeting him tomorrow.
I will be meeting him tomorrow/next year.
2/现在进行时表示最近将来的动作时，必须有确定的表示将来的时间状语；而将来进行时则没有这种限制。
He's working in this room nest Monday. 他下周一将在这个房间里工作。
He'll be working in this room. 他将在这个房间里工作。
少见用法：表示背景动作——提供另外一个短动作发生的事件背景
They probably will be watching TV when we get there.
Will your friends be waiting for you at the airport when you arrive?
What do you think she'll be doing when we get there?
难点用法1：用在疑问句中，表示客气地询问
Will be doing礼貌的询问，常表示很客观地询问事实，并不想干涉对方的决定；而 will do往往带有各种感情色彩，如请求，命令，指示，质问甚或威胁等等。
How long will you be staying?
How will you be paying?
Will you be spending your holidays abroad this year?
When will you pay back the money? 你什么时候才能还这钱啊？
When will you be paying back the money?这钱你什么时候能还一下？
Will do 往往带有各种感情色彩，比如表达 “请求”，此时就得用will do :
Will you lend me ten dollars?
所以，如果是要客观地询问事实，宜用 Will be doing来提问；而若是其他语气，比如请求或命令等，则要用will do来提问。
Will you be staying in this evening?
Will you stay in this evening?
难点用法2：用来表示客观的将来，以避免与表示“意愿”的will do混淆
will not be doing 是表示客观的将来时间（较客观），以避免与表示“意愿”的will do混淆（较主观）。
If I fail to show up by 7 o'clock, I will not be coming at all.
此处的｛will not be coming｝是指客观将来的时间，是为了强调是“我来不了”而并非“我不愿来”。
He won't resign.=he refuses to resign. 他拒绝辞职。
He won't be resigning.=I guess he will not resign..我想他不会辞职。
