the provision of safe water necessitates one of the rnajor expenditures of manpower and revenue in our modern cities. the purification of water is basically a two-step or three-step process carried out under the strict supervision of public health scientists and engineers. as the first step,natural water from the least contaminated source is allowed to stand in large reservoirs,where most of the mud,clay,and silt settle out; this is called "sedimentation". often in water with high mud content,lime and aluminum sulfate are added to the water in the settling reservoirs. these chemicals react in the water to form aluminum hydroxide,which settles slowly and carries much of the suspended material,including most of carries much of the suspended material,including most of the bacteria,to the bottom of the reservoirs. as the second step,the water is filtered through beds of sand and grovel,which remove other impurities and chemicals in it. during or after filtration,chemicals are ordinarily added to the water to kill any remaining harmful bacteria. chlorine is one of the most common chemicals used for this purpose. a third step taken by some rmnicipalities is adding to the water other beneficial chemicals such as fluoride to make tooth enamel hard,and soda ash to make the water itself soft. the water purification process,carried out with little variation from one large city to another,is perhaps the biggest factor in the prevention of major outbreaks of disease in this country.

六(3)班作文周报

作者：秦延

暑假里，我们家闹了一场“水灾”。

早上，我正在熟睡，突然听到奶奶大声喊起来：“快起来，运沙子去！”我正在迷糊呢，奇怪，好好的，运什么沙子啊！可是当我睁开眼睛，看到屋子里的积水时，不禁大吃一惊：“天哪！这么多水！都漫进屋子里了！”

此刻，我完全没有了睡意，赶忙穿好拖鞋去帮忙。奶奶让我去把爸爸喊起来。我跑到爸爸身边，大声喊道：“抗洪救灾呀！老爸！快！”可是人家一点反应也没有，还以为我在逗他玩呢。还是奶奶厉害，走过来说了一句：“赶紧起来，你以为秦延逗你玩呢？快！”

我站在家门口，一眼望去，门外早已水汪汪的一片了。我打着伞，走在水里，又想到应该去爸爸那里帮忙。我正往爸爸那边走时，不小心把拖鞋甩了出去，我用力往前蹦，想去拿鞋子，可是每蹦一下，水就往我身上溅一下，最后只好光脚走过去拿拖鞋。唉，忙没帮上，自己却弄得这么狼狈。

等把客厅的门用沙子塞上了，我开始真正忙活起来了，因为要把水往外面泼。我一手拿着勺子，一手端着盆，不知道的还以为我是大厨呢！过了好一会儿，水全部被清出去了，我也累得够呛。

下午，水没有了，院子里的地面也变得干净了许多，可是，我又没有乐趣了。

发大水后
今天一早起来，天放晴了。哪知道今天的水比昨天漫得更高了，电也停了，保安说昨晚已没到了储藏室，小区里的几辆车快没到车窗了，我们一家赶快去外面看看。

我们在水路上慢慢地行走，别有…番滋味，往常车来车往热闹的马路再也看不到车的踪影了，路上行人有的乘坐黄包车去办事，有的乘着竹排或橡皮艇去上班，真像威尼斯的水上城市。路边有儿辆车整个都浸泡在水里，只剩下可怜的天窗了。大部分的店关门了，就连农工商超市也大门紧闭。我跟妈妈庆幸昨天已经做好了准备，在三和超市买齐了足够二三天吃的粮食。昨天没到我大腿地方的水今天已没到了小肚子。突然听到有人说在我们三星小学大门的快餐店附近有好几条蛇出没，不知是不是毒蛇，万一钻进停在水中的那些车子里，然后冷不防地出来咬一口，那多恐怖啊！我马上汗毛就竖起来了。

我和妈妈来到公园边，要求爸爸用手机给我们拍照，在一片汪洋的马路上留个纪念。这时一位伯伯说他停在最高处的车也进水了。我们又马上走到昨天停车的农工商超市门前，只见我们的车牌昨晚已被水泡过。打开车门，里面都是水。幸好昨天做了准备，爸爸说排气管应该没进水，可车一打开就“滴滴滴”地叫个不停，门已无法上锁了。电话打到4S店询问，原来是车的线路板泡水已烧坏导致的，保险公司要求我们把车拖到4S店维修，可是看看周围停满的横七竖八的几百辆车，怎么才能拖出去呢？唉，真不知这车要在这里困多久！

听大人们说这次的发大水还真厉害，不看不知道，一看吓一跳，听说市区最深的地方有1.78米左右，怪不得电视上几个小孩套着救生圈在游泳呢！洪水还淹没了农民伯伯的农作物。我原来以为发大水是件好玩的事，没想到带来这么大的损失，真希望老天爷的雨以后不要再下个没完没了了！

Look,red hawthorn,yellow persimmons,like sapphire,blueberry,often hosted peoples feet,let people stay.

When the snow is under the snow,the mountain is covered with snow,it seems to be put on a silver dress. There is a small river in the foot of the mountain,the water is calm,quiet,you cant feel it in the flow; the water of the stream is clear,you can see the river. A wind blows,the river is water,like a fine line,a circle of ripples. The water like a small river moisturizes people in the green hills.

Ah,I want to praise you - beautiful hometown,I love your landscape,I will make you more beautiful in the future.
