    Your parents love you and care about you. As a teenager, you should do what you can make them happy. Here is some advice.

    Do your chores. Help your parents with when you see them working around the house. Do your chores without being asked to and do so more than you are asked to.

    Develop interest something. Find out what you are good at, and join a club that can help you improve you. It's good to have hobbies. Having something that your parents can hang on the walls like a painting will bring them much happy.

    Talk with your parents good. Do not talk back to (对……顶嘴) your parents when they understand you. Find a right time talking with them. They will be glad to take time talking with you.

    Can a kangaroo (袋鼠) live in the tree? Look at the picture! There is a orange and brown animal in the tree. It is a kind of kangaroo—the Matschie's tree kangaroo.

    Matschie's tree kangaroos weigh between 7 and 11 kilos and they can live up 20 years. Each of them has a long tail like the other kangaroos, but there are some difference between them. Matschie's tree kangaroos have longer and stronger front legs and thick fur (软毛).

    Matschie's tree kangaroo's food including tree leaves, flowers and grass. Mother tree kangaroos give birth to one baby each time. Do you know how the baby lives? Of course in the pouch (育儿袋) of the mother. The baby lives in it for about ten months.

    The number of Matschie's tree kangaroos becomes little now because people cut down trees and kill them for meat and fur. They are dangerous and they really need protection. Tree Kangaroo Conservation Program is doing research in tree kangaroos. We hope there will be more tree kangaroos in the future.

    During the summer vacation, my parents and I went to Beijing for a trip. On the first day, we visited the Palace Museum and took many pictures at there. On the second day, we went to climb the Great Wall. It is one of the greatest wonder in the world. We saw lots of tourists and learned much information about it under the help of the tour guide, Miss Yang. At last we went shopping in the city centre of Beijing Wangfujing Street. We bought a lot gifts for our friends.

    We enjoyed our trip very much. It was an excited experience and I will never forget it.
