The paper tackles the issue of language teaching by means of language-based Internet websites paying particular attention to teaching the language for specialized purposes. It foreshadows the potential of Internet to function as a supplementary source of language information and training as well as that of self-contained material which is capable of covering virtually every area of language learning - grammar, spelling, specialized expressions, pronunciation etc. The emphasis is laid on how all the above mentioned categories can be combined and harmonized to produce concise worksheets targeting specific areas (biology, medicine, computer science etc.), their specialized terminology and merits of working with such material. The demonstration of samples of worksheets, tests and pronunciation exercises represents a major part of the paper. All these utilize web design (HTML, CGI scripts, JAVA scripts) and common methods of Internet audio transfer to meet the modern learner's language needs. The paper is given in English.
