THE PHENOMENON OF ISOMORPHISM IN SIMPLE AND COMPLEX SENTENCES WITH DETERMINANT

The simple and complex sentences according to similarity characteristics are considered: the presence of determinant. It is proved that the so called phenomenon of isomorphism appear, which is in structural-composed, semantic and functional plans and plan of determination. The common features of simple and complex sentences are revealed and considered as the most efficient use of one of characteristic principles of system language description that means: the principle of unification that gives the ability to present in compression the functioning of language system at syntax level. It is established that this approach to Russian language studying in Russian language auditory where Russian is learned as a foreign language, minimizes and makes easier the process of simple and complex sentences structure in Russian language. The “real” complex sentences are those having the theme and rheme at the first level which are not simple members of the sentence but predicative syntagma. The second place take complex sentences which have determinant the member of a sentence which refer to all predicative syntagma included in the complex sentence. The third place take simple determined sentences in which the thematic-rhematic articulation exist, there theme is a part of sentence referring to the whole sentence and rheme is a predicative syntagma.
