Kathy is my best friend. We have known each other since we were children. In the last few years, she

has changed a lot. In the past, Kathy was short and had short hair. However, she is tall and has long hair

now. when she was in the primary school, she used to be shy. These days, she's outgoing and has more

friends. She used to be afraid of dark, so she was terrified of being alone at home in the evening. Now she

isn't afraid of that any more and she often does homework by herself at home in the evening. When she was

a child, she liked to eat junk food and ate it at least three times a week. These days, she likes vegetables and

fruit. She only eats junk food once a month, because she knows eating too much junk food is bad for her

heath. When she was in the primary school, she used to walk to school. Nowadays, she takes a subway to

school.

     Though Kathy has changed a lot, we are still good friends.
