    The water we drink and use was running short. We all have to learn how to stop wasted water. One of the step that we should take is to find ways of reusing them. Today in the most large cities, fresh water is used only once and then it runs in a waste system. But it is possibly to pipe the used water to a purifying factory, when the used water can be treated with chemical materials by the workers sothat it can be reused. But even if every large city purified and reused it's water, we still would have enough water.

    It is a pity that you don't want to take part in the speech contest. As far as I am concern, the speech contest can benefit from you in different ways. To begin with, it urges you to look for more information about your favorite scientists on the Internet or in the library, and learning more about them. Beside, it is a challenge to make preparation for a speech contest. Not only you have to write a good article, but also have to perform them properly. What's more, you can make some new friends in the contest. I suggest you considered participating in the contest, what will really do good to you. If you change your mind, please let me know as soon as possibly.

    My old classroom was interesting because three side of the classroom were made from glass. I enjoyed sit close to the windows and not looking at the view. On the left side I could easy see the football field. On the fight side I was always interested to see the drivers in hurry in the morning. The view from the back of the classroom is wonderful：there was a beautiful park with many trees around them. The position of the classroom with its view made me felt like I was dreaming. If I was only a child when I studied in that classroom, I will never forget it.

    During the summer vacation of my first year in high school, I just stay at home all day long, lying in bed and listening to music. Even my father got tiring of seeing me lying in my rooms. One day, I thought I couldn't live in this way any longer, but I asked my father if he could buy us a basketball and he said yes. He told me that if I really wanted play, I would need to show him. Every time he saw me playing the basketball with my friends, he smiled. Gradual, I became so active that I could concentrate much on my studies than before. Physical activities does help build our character.
