My best friend is Lan. We have known each other since we were 10 years old. However we became best friends when we were at grade 7. At that time I was very bad at English and it was who helped me improve my English. Now she lives with her parents in Nguyen Trai street.

If I were to describe how she looks I would say she is very pretty. She has long black hair a straight nose and a small pointed chin. She is quite slim. She doesn t like to dress up so I usually see her wearing jeans and a T - shirt. She has a very nice personality and a wonderful sense of humour but she can also get a little depressed from time to time. I can always count on her to be honest and to give me the best advice.

What I like about Lan is that she has same hobbies with me. We both enjoy singing karaoke reading comic books and going shopping. We like going to the cinema but sometimes can t agree on which movie to see. In addition since I am better in Maths and Chemistry and she is better in English and languages we can always help each other if we get confused about a difficult homework assignment. We are so lucky that we get along so well. I hope that our friendship can last long.

1:My school is beautiful. School yard, through not very large but very spacious and clean. High school entrance and spacious, the two sides is the flower corridor leads straight to the playground and the classroom. School Grounds em wide, around the yard Poinciana trees and ancient eagle shade cover, with flower beds and lawns green. Listed under the tree row of stone for us to read books and talk after each lesson. The classrooms are full of tables and chairs, cabinets for learning and also exhibited the post office corner, nice article. In addition, you also have the other classroom as music room, computer science, library, classroom English ...I even loved the school because here we have good friends and the teachers are always interested to teach and impart knowledge to us so people. I loved my second home!
