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.

2. Talk about your school

There is a white three-storey building, surrounded by greenery, located at Simei Town Central. That is Simei Primary School. That is also the place where I have schooled for the last five years or so.

My school uniform is white. The boys wear a white shirt and white shorts while the girls wear a white blouse and skirt. The uniform must always be worn with the school badge which bears our school motto “Nothing without labor”. It means that we must be willing to work to get our reward. We are also taught to be honest and polite all the time.

Most of the teachers in my school are just and kind. However, there are some teachers who show favoritism. As a result, the students who are favored by these teachers are very proud and like to bully the others. In general, however, we all treat one another like siblings and live in harmony.

I am sad that I will have to leave my school at the end of this year. It has given me knowledge, friends and happy moments. I will always remember my school and the fond memories it holds.
