You received an email from your English friend, Jane. She asked you for some information about one of your friends. Read part of her email below.

I’ve just got an email from your friend, An. She said she’s going to take a course in London this summer. She asked if she could stay with my family until she could find an apartment. Can you tell me a bit about her (things like her personality, hobbies and interests, and her current work or study if possible)? I want to see if she will fit in with my family.

dear Jane

i am very happy when i received your letter. i'm writing this letter to tell you about information of Lan I had knowed before. We have been friend in a long time, i studied with her in secondary school and high school. She is a kind people, friendly and have a nice face, maybe i like her face a little it's really beautiful. Besides, her character very kind and closed with everypeople meet her, she usually help people when they get a trouble. In addition, she is a hard student in my class, her backround very execellent with many high scores. As i see, her hobbies is reading book and painting, sometimes i had seen she join in sport club in my local.
