As a colourless, neutral synthetic future which is to be found in Russian and French it is non-existent in English. O. Jespersen, Palmer, L. Barkhudarov hold that shall and will are modal verbs meaning obligation and volition. English does very well without regular auxiliaries to express futurity (The train leaves tomorrow. The train is leaving tomorrow. The train is to leave tomorrow. The train is about to leave tomorrow. The train is on the point of leaving). We do not find the Future in clauses of time and condition ( If he comes, tell me about it. When he comes, tell me about it).
According to N.A.Kobrina, B.A.Ilyish, E.A.Korneeva, the English Tense system is represented by the opposition The Past : the Present : the Future. These scholars find that shall and will indicate merely futurity , they have become fully grammaticalized, losing their modality. N.A. Kobrina and E.A.Korneeva add that there exist two constructions shall/will + infinitive, in one shall and will are modals and in the other they are future auxiliaries. When they are auxiliaries, they can be contracted into ‘ll. This marker of futurity can be attached to any class of words (What he says’ll have authority).
M.Y.Blokh distinguishes newer categories within the Future. On the basis of the oppositions come :: shall come, come :: will come he distinguishes the category ofprospect, on the basis of the opposition shall come:: will come he distinguishes the category of futurity option. The distinction between the members of this opposition is neutralized in the element ‘ll. Shall and will are not substitutable. Will can be used in all persons, shall is relevant only for the first person singular and plural. So we can conclude that The Future is an unfinished system in English.
