Ex 3 Read the email and answer the following question.: ( 1,0 point) Dear Phong, I’m sorry I couldn’t write to you early because I was very busy. Now, we’re staying in a small hotel near a shopping area in District 10. Near my house, there is a cinema, a post office, a supermarket and some cafes. There are some big shops at the end of the street. It is also very noisy here because there’s always a lot of traffic day and night. In my hometown, I live in a quiet street, there are some small shops, a school and a post office in my neighbourhood but there isn’t a park and a cinema. The streets are narrow but they are cleaner and there isn’t so much traffic. The air is much fresher, too. And every house has a backyard and a frontyard. Love, Nam. 1.
