My family consists of four people. There are my parents, my brother and me. My father is an engineer. My mother is a housewife. My brother is a student, and I am a police. We get up at 6 o’clock every morning. After breakfast, I and my father go to work, my mother does the housework and my brother goes to school. We have lunch at noon and dinner at 7 p.m. In the evening after dinner, we sit together in the living-room talking or watching television for about an hour. Then my brother and I go to our own rooms. My family is a very happy one. We love each other very much and expect to live together under the same roof forever.
