    Four ways to have a good school life

    Your schooldays should be some of the best and happiest days of your life. How can you get the most from them, and be sure you do not waste (浪费) this great chance to learn?

Be active(积极的) at school

    Don't say things are difficult or boring. Take interest in school life and your school subjects. Join lots of activities. Put up your hands quickly in class. Go around the school with a big smile. If you are not working, you are wasting your time at school. Teachers cannot make everything enjoyable（令人愉快的）.

Keep fit

    If you don't eat a good breakfast, you will be thinking about food in class. If you go to bed late and don't have enough sleep, you will be sleepy in class. Play enough sports every day in order to keep your body strong.

Face the problem

    Do not say you will do things tomorrow. If you get behind the class, it is very difficult to get back in front. You cannot finish the race if you rest all the time. Everyone fails some exams, loses some matches and has bad days. Don't make small problems very big and important. Don't forget to ask for help. You are young, and no one thinks you must do everything quite well!

Spend the weekends

    Don't waste time lying in bed on Saturday or Sunday morning. Go and play sports, get together with friends in the park to relax, learn to play the piano, or help someone with problem. If you don't want to go out, there are also a lot of things to do. You may read a book, practice English or help Mum with housework.

    Follow our advice, and have a happy school life!

    We are living in a colourful world with green trees, red flowers and the blue sky. Everything has its colour. Our moods also have different colours. I am a middle school student. Yesterday, I didn't want to get up early for school, but I was woken up by mum at 6:00 a.m. At that time my mood was like grey fog. I felt tired and sleepy.

    At noon, I helped a blind man cross the road on my way home. The blind man thanked me a lot. I felt very happy and the mood was like the red sun. It made me warm and sweet.

    In the maths class, my red mood changed to black, because I failed the exam. When I got the exam paper, I couldn't stop crying. But Mr Li told me to keep on studying hard.

    After school, I walked home and thought about Mr Li's words. I felt comfortable and energetic.

    The mood was like the blue sky, sunny and peaceful.
