The category of mood. The category of voice. The category of tense

The category of tense.

• 3 basic categories of the verb: aspect, correlation and voice. They are constituted by 2 forms of the verb – analytical and non-analytical. The categories of mood, tense and person are basically different. They are characteristic of only finite forms of the verb. The category of tense, being a predicative category, differs from other categories in its structure, grammatical meaning and its syntactic function because it is connected with the essence of the speech act, with interpersonal relations.

The opposition of past and present is not the opposition of just 2 verbal forms but the opposition of 2 systems of forms:

Present:	Past:
works	worked
Is working	Was working
Has worked	Had worked
Has been working	Had been working
Is going to work	Was going to work
Is to work	Was to work

• Functionally all the forms, entering these two systems, are the same. They’re used in the syntactic function of the predicate in the sentence. But in speech in the plane of communication the present forms reveal their specific character: they reflect facts and evens as actual, immediately related to the participants of the speech act. On the contrary, the forms of the past reflect something that is already the past, history, not immediately related to the participants of the speech act. What is represented by the past forms is of some cognitive interest to the addressee.
