4. Read the text. My Day Off Most people in our country work five days a week but students and pupils work six days. They have only one day off. It is Sunday. I like this day very much. You needn't hurry anywhere and you may go wherever you like after your week's work. On this day I wake up later than usual. But sometimes I don't get up till nine or ten o'clock. I read morning newspapers or listen to music. As soon as I get up I air the room, make my bed and do morning exercises. Then I have breakfast, clear away the dishes and wash up. Two more hours for getting ready with my homework and I am free. I meet my friends and we discuss our plans together. We may go to the cinema or theatre, to museums and parks. Last Sunday we went to the Botanical Garden. There were many beds of spring flowers there: red, yellow and blue. People in light clothes were walking along the paths. The air was fresh and promising. It was very pleasant to spend time there. In fine weather we also like to be out of town. We find a nice place somewhere in the forest or on the bank of the river. We lie in the sun, play different games and swim. In winter my friends and I often go to the skating-rink. Skating is my favourite kind of sport, but I like to ski too. When the weather is bad my friends come to my place. We listen to music or go to the cinema. We like films about the life of our contemporaries abroad. On the way home we usually discuss the films we've seen. In the evening all the members of our family get together. We have our supper, make plans for tomorrow, watch TV or read books. Reading is my hobby. Sometimes we receive guests at our place or go out for a walk. In general I enjoy my days off very much.
