Knowledge of the foreign language is becoming more important nowadays. There are many reasons why we study English. Now, in a period when we are reconstructing our economy, when there are many joint ventures with foreign companies operating in our country, we need a number of specialists who know foreign languages. If you know English, you can communicate (personally or in writing) with others who use this language.
If you wish to make a career in science, you must read scientific books and magazines in English. Knowing English you can read the works of foreign writers in original.
A more general aim is to broaden our intellectual and cultural horizons through contacts with people of other countries.
Knowledge of foreign languages helps people of different countries to develop mutual friendship and understanding.
