Test II 1. Read the text Dear Hans. Thank you for your letter! I will answer your questions about my family with pleasure. Today is Sunday, so we are all together. It is raining, that's why we are all sitting in the living room. My Mom is reading. She is a teacher of literature, so she reads a lot. She is a slim woman of about 40. Her pupils like her for she is a kind person. Reading is her hobby. Besides, she likes cooking. When we have dinner together after a working day, there is always something tasty on the table. My father is a doctor and has very little free time. He works a lot. When I was a child, I often visited him at the hospital and saw him at work. He always listens attentively to his patients and gives them his advice. He decided to become a doctor, because his father, my grandfather, was a doctor too. They look very much alike. My grandparents live in the village, where my parents come from. They are happy to see the entire family when we come to them. We have many relatives. My aunts, uncles, and cousins live in different parts of Russia. On holidays we often take trips and have a very good time! Yours, Ann Mark the sentences as true (D) or false (1) 1) Ann's mother is a teacher of literature 2) Her mother likes cooking and reading. 3) Ann's father doesn't work in the hospital. 4) Ann's grandparents live in the village. 5) Ann has not got many relatives. 6) Ann's family likes to go on trips on holidays.​
