Об эксплицитности, форме и определенности субъекта в русских и чешских модальных конструкциях

The article makes an attempt at explaining the substantial differences between Russian and Czech in the ways of expressing the subject in sentences with modal verbs and predicative words. These sentences are classified according to whether their subject is expressed by a separate word, whether it has nominative or other form, and whether it has definite or indefinite reference. The conclusion is made that in Russian there is a much higher percentage of sentences with a non-expressed non-nominative subject which are also used in such communicative situations where Czech uses constructions with a pronominal or a verbally non-expressed subject.
