5.与将来完成时的区别：

（1）将来完成时（will have done）：强调“到将来某时已完成的动作”。

如：He will have finished the book. 他会读完书。

（2）将来完成进行时（will have been doing）：强调“到将来某时一直在持续的动作”。

如：He will have been reading the book for 3 hours.

他会一直读书读了3小时。

（3）动词选择：多用延续性动词（如work, live, study, wait），不与短暂性动词（如finish, arrive）连用（短暂性动词可用完成时，但进行时无意义）。
