The Subjects We Studied at School. My Favourite Subject
Let me introduce myself. I’m Kate Belova. Now I’m a student of teachers’ training college. I finished school 2 years ago. We did quite a lot of subjects at school. They were: Mathematics, Physics, Chemistry, History, Geography, Russian, English, Literature and others. Every teacher asked for equal and adequate attention to his subject and it was not an easy work to do. I knew that all the subjects were important, but still I was always indifferent to exact sciences. Since my childhood I have been fond of reading. My favourite subjects were Literature and languages. When I started studying English, the first thing I got interested in, was the different way to express one and the same idea in English and Russian. I wondered why if an Englishman is upset or gloomy he does not say: "I have a bad mood" like Russians do but says: "I feel blue". There is an infinite number of such things in any language. I read English books, tried to translate some articles from "Moscow News". Very often I borrowed English books from our school library. I spend a lot of time studying Grammar and doing exercises. At our English lessons we read quite a lot, but didn't talk much. So I and my friends decided to speak English among us. Very often I spoke English with my friends on the way home after classes.
