Napoga is a 12-year-old girl in Ghana(加纳), Africa. It is hard for her family to get clean water. Every morning, she leaves home at half past five to get clean water for her family in a village far away. It takes her six hours to get enough clean water for daily cooking and drinking. She has no time to go to school or to play with her friends. Millions of people in the world are like Napoga. They can’t get enough clean water to keep healthy.
Earth Day is April 22. But on all other days, we must also remember it. The water we use is the most important natural resource on the earth.
Water covers 70% of the earth’s surface. But most of that is sea water. We can’t use it for very many things. Fresh water covers only 1% of the earth’s surface.
You probably feel lucky that your life isn’t as hard as Napoga’s. But that doesn’t mean you don’t have to worry about water. We all face serious water problems. One of them is water pollution. All kinds of things from cars, factories, farms and homes make our rivers, lakes, and oceans dirty. Polluted water is very bad for people to drink. And dirty water is bad for fish, too. Now, 34% of all kinds of fish are dying out.
How do cars and factories make our water dirty First, they pollute the air. Then, when it rains, the rain water comes down and makes our drinking water dirty. Dirty rain, called acid rain, is also bad for plants, animals and buildings.
Scientists say that in 30 years, more than half of the people in the world won’t have enough clean water. We have to learn how to save more water for ourselves and our children. Here is some advice for saving water:
· Turn off the water while you brush your teeth. You can save as much as 450 liters each month.
· Leaky taps waste a lot of water. Fix them right away!
· You can easily cut your 10-minute showers in half—and you’ll be just as clean.
· When you wash dishes, don’t let the water run.
· Only wash clothes when you have a lot to wash. If your washing machine isn’t full, you’re wasting water !

Every morning Napoga went to get clean water ______.

A.before she went to school

B.after she finished school

C.without going to school

D.after she played with her friends

背景资料:xx年5月10日,某公路工程处第三项目部在某立交桥施工期间,对立交桥作业区域内原有厂房拆除工程施工中,发生了一起因被拆除的建筑物坍塌导致2人死亡的事故。某建设单位委托第三项目部进行2000m2厂房拆除工程的施工,厂房是砖混结构的两层楼房,要求6月底前拆完,合同工期4个月,条件是第三项目部向建设单位上交3万元,拆除下来的钢筋由第三项目经理部支配。项目部又将此项工程分包给了M民工队,条件是以拆除下来的钢筋作为支付M拆除施工的工程款,并于2月20日签订了合同书。拆除工程施工前,建设单位未向建设行政主管部门申报,也未给项目部提供厂房图纸等技术资料。项目部要求民工队3月1日开工,民工队为了能以最小的投人获取最大的收益(旧钢筋),未支搭拆除工程施工脚手架,而是站在被拆除厂房的楼板上,用铁锤进行作业。5月10日,厂房只剩最后一间约16m2的休息室时,民工L、H和C站在休息室天花板(即二楼地板,二楼已被拆除)上,继续用铁锤锤击天花板。同日下午16:45左右,房屋中心部位的天花板水泥已基本脱落,民工L、H和C仍用铁锤锤击暴露出来的钢筋,致使天花板呈V字形折弯,继而拉倒两侧墙壁,C及时跳下逃生,L和H被迅速缩口的天花板V字形折弯包夹。L在送往医院途中死亡,H在经医院抢救1小时后死亡。
