2.Now, I want to tell you about my lovely house. My house locates in country side of HaiPhong city. It takes about twenty minutes to get my home from center of HaiPhong. If you come to my house, the first thing you can feel is warm feeling. My house is not a big house, either a modern house. It is only a small house with a large garden. My younger sister often plants flower infont of our house. In my garden, you can find many kinds of plant. They are vegetables, fruits ... And I'm sure that any season you come my house, I can have some types of homeplanted fruit for you. And another exciting thing is that you can fish in my pond. With a hat on your head, a fishing rod, you can have a relax time. I love my house very much. Whenever have to go far for work, I always remember my home so much and want to come home as soon as possible.

3.Everyone of us has at least one best friend to share happiness and sadness. So do I. My best friend's name is Linh. I can say she is my closest friend since we were the children. We have grown up in the same town , went to same school and even studied in the same class. Linh is quite good-looking. She is tall and thin. She has a round face, brown eyes and thin lips. She is a helpful and friendly girl. She has talent in Maths so sometimes when i get troubles , she always explains comlex Maths theories in simple ways to help me understand. I spending time with her because we have common things together. That's why she understands me including my hobbies and diss. The best thing I about her is sense of humor. She always has useful ways to make me laugh whenever I'm sad or angry. I really treasure our friendship and hope that it will last forever

4.I really love my neighborhood. It is a quiet, safe place with great neighbors. In short, my neighborhood is nice to live in.
My neighborhood is quiet. Even though it has the regular amount of noise of any place, there are many peaceful moments. For example, after most people have gone to work, you can hardly hear any noise. Of course, when the kids get home, there is more noise; but, it is relatively quiet all day in my neighborhood.
Also, I feel safe in my neighborhood. The police drive everyday and the kids play outside with no problems. Since there is not much traffic, we don’t worry too much about cars.Furthermore, I can walk around my neighborhood without being afraid of someone hurting me. All in all, my neighborhood is secure.
My neighbors are really good people. They watch out for each other and this makes where I live extra nice. If anyone has a problem with their car or even something in their house, a neighbor is usually there to help. One day, I couldn't start my car, and my neighbor asked what was wrong. I explained that my car wouldn’t start, and he got my car going again. This is just one of the many examples of how my neighbors are the best people I know. In conclusion, my neighborhood is a great place to live .There is no place home and that is my neighborhood.
