The future tense of the verb _walk_ is conjugated as follows: I shall walk We shall walk You will walk You will walk He will walk They will walk This is the form to use when you expect the action to take place naturally. On the other hand, instead of letting things take their natural course as they do in the simple future, you may force them to take place. You may, for example, be determined to walk, or determined to make some one else walk. In that case the use is reversed; as, I will walk We will walk You shall walk You shall walk He shall walk They shall walk This form is used whenever the speaker has authority to bring about the action indicated by the verb. In questions of the first person always use _shall_. In questions of the second and third persons use the same form that you expect in the answer; as, _Shall_ you be at home to-morrow? I _shall_.
