The UN passed a rule in the year 2004 to improve the quality of drink water and reduce deaths caused by drinking unhealthy water each year. The UN has already worked out the specific plan to reduce half of the number, that is, five thousand. The UN announced in the world there are about 1/6 of the world population can't meet the sanitation regulation of drinking water.
The water we drink and use is running short in the world. We all have to learn to stop wasting our quite limited water. One of the steps we should take is to find ways of reusing it. Experiments have already been done on this field. Today in most large cities, fresh water is used only once, then it runs into waste system. But it is possible to pipe the used water to a purifying(净化)factory. There it can be filtered(过滤) and treated with chemicals so that it can be used again , just as it were fresh from a spring. But even large cities purified and reused its water, we still would not have enough. Then we could turn to the oceans. All we would have to do to make use of seawater on earth is to get the salt out of it. This method has already been used in many parts of the world.

I was a newcomer of Miss Burn’s seventh grade. Past“newcomer”experiences had been difficult, so I was

very anxious to fit in.

    Lunchtime was a pleasant surprise when the girls all crowded around my table. Their chat was friendly, so

I began to relax. My new classmates filled me in on the school, the teachers and the other kids. it wasn’t long

before the class herd(书呆子)was pointed out to me: Mary Lou. Actually she called herself Mary Louise. A

formal, overmodest young girl with old-fashioned clothes, she wasn’t ugly—not even funny looking. Practical

shoes, long wool skirt and a blouse completed the image of a complete herd. The girls’ whispers got louder and

louder. Mary Lou didn’t notice this. After school, the girls invited me to join them in front of the school.

   Arms wrapped around her backpack, Mary Lou came down the school steps. The taunting began—rude,

biting comments and disrespectful words from the girls. I paused, then joined right in. My force began to pick

up as I approached her, mean(卑劣)remarks falling from my lips. I even pulled the belt of her backpack and then

pushed her. The belt broke, Mary Lou fell. Everyone was laughing and patting me. I fit in. But I was not proud.

Something inside me hurt.

   Mary Lou got up, gathered her books and—without a tear shed—off, she went. She held her head high as a

small trickle of blood ran down from her injured knee.

   I turned to leave with my laughing friends and noticed a man standing beside his car. His skin, dark hair

and handsome features told me this was her father. Respectful of Mary Lou’s proud spirit, he remained still and

watched the lonely girl walk toward him. Only his eyes—shining with both grief and pride—followed. As I

passed, he looked at me in silence with burning tears that spoke to my shame and scolded my heart. He didn’t

speak a word.

   No scolding from a teacher or a parent could linger(逗留)as much as that hurt in my heart from the day a

father’s eyes taught me kindness and strength and dignity. I never again joined the cruel herds. I never

again hurt someone for my own gain.
