I study at the Bookselling College. I get up at a quarter to seven. I switch on the radio and exercise to the radio music. Then I go to the bathroom, wash myself and clean my teeth with a tooth-brush. It takes me not more than ten or fifteen minutes. Then I dress and sit down at the table to have my breakfast. I usually have a cup of tea or coffee, eggs and bread and butter. After breakfast I go to the college. I go there by metro and by bus. My lessons begin at 9.30. At twenty minutes to one we have a lunch hour. We study many subjects. Best of all I like English and literature. When I studied at school, I liked English and literature too. At eight or nine o’clock I have supper. I have some salad, a slice of sausage and bread, sour milk or cereal. In the evening I do my home-work. I must and can do it well. Sometimes I listen to the radio or watch TV. In the morning I am going to the college again. Задайте к тексту 5 вопросов на английском языке
