will soon be taking place，will soon be claiming，will be taking 这三个will be doing 在形式上看似将来进行时，但句子并没有一个将来时间点，表示在该时间点动作正在进行。所以这里不是普通的将来进行时，而是语法书中所说的“纯粹将来”，即说话人认为事件在将来的发生是理所当然的, 是与主语的意志、意愿无关的，是预先确定的。

剑桥英语语法对此的解释如下：

ii Will you be going to the shops this afternoon?

The meaning can best be seen by comparing it with the non-progressive counterpart, Will you go to the shops this afternoon? The salient interpretation of the latter is as a request to you to go to the shops, and the role of the progressive in [ii] is to avoid such an interpretation.The progressive indicates that the matter has already been settled rather than being subject to decision now. Compare, similarly, We won’t buy any more (interpretable as a refusal, made here and now) vs We won’t be buying any more (following prior decision), or Will he help us? (“Is he willing?”, decision still to be made) vs Will he be helping us? (“Has it been decided that he will?”).

夸克对此的论述如下：

There is, however, a separate use of the will/shall + progressive construction to 'denote 'FUTURE AS A MATTER OF COURSE'. The use of this combination avoids the interpretation (to which will, shall, and be going to are liable) of volition, intention, promise, etc:

We'll be flying at 30 000 feet.

This, spoken by the pilot of an aircraft to his passengers, means '30 000 feet the normal and expected altitude for the flight'. If, on the other hand, the pilot said:

We'll fly at 30 000 feet.

the impression might be quite different: it could well be that the pilot had just decided to fly at the specified height.
