Task 6 (28 points). Read the text and give full answers to the questions. Dear Sam, How are you? I want to thank you for your invitation to stay at your cottage. Your house is nice and is very different from my flat. The rooms in my flat are much smaller. The windows are bigger, but the ceiling in my flat is higher. There is a big yard. I like to read books there. Living in the city really differs from living in the countryside. In the city, I can go to the mall or to the cinema, but I can’t walk in the fresh air or see many birds. In the city, there are a lot of people everywhere, so I can’t sit in the park and read a book or enjoy the peace and quiet. It’s really nice to spend some time in the countryside, to have some rest. I really hope you will come soon. Best wishes, Amy 1) What kind of dwelling does Sam live in? __________________________________________________________________ 2) Which dwelling has the biggest rooms? __________________________________________________________________ 3) Which home is in the countryside? __________________________________________________________________ 4) Where does Amy read books? __________________________________________________________________ 5) Which place is peaceful and quiet? __________________________________________________________________ 6) Where are the biggest windows? __________________________________________________________________ 7) Where can Amy go to the cinema or the mall? __________________________________________________________________
