汹涌澎湃的是海水，碧波荡漾的是湖水，潺潺不绝的是泉水，清澈见底的是溪水……
水，常温下不过是一种透明无味的液体，可是到了摄氏零度时就变成晶莹的冰花，摄氏百度时又会变成腾腾的“热雾“。不过可不能小瞧了它。水是生命摇篮。没有了水，就没有一切。
生产离不开它。工农业生产哪一顶不需要水？黄河上游的发电站发出了百亿度的电，其源泉是水的动能；成顿的钢材，在水压机上揉面团似的锻压成各种形状，靠的还是水的动能；商店里一匹匹色彩斑斓的布料，纺织、印染时离不开水。还有农田里飘着清香的蔬菜，诱人垂涎的瓜果需要水，一望无际的碧绿的庄稼不能没有水……整个绿色世界和人类赖以生存的食粮，都是水和光的结晶。
生活离不开它。人们日常生活中，又有哪一项不需要水呢？做饭、饮用要水；洗衣、洗澡要用水；在国际上一举夺魁的作大名酒，原料也是水；奥运会上鏖战的健儿们的饮料也离不开水……
地球素有“水的行星“之称，地表的百分之七十也被水覆盖，可别就以为它是“取之不尽，用之不竭”的。非洲缺水已造成空前的灾难，还有废水的污染，使许多江河湖海的水变色变质。解决用水困难，除了有待利用地下深层水、冰山的雪水外，目前只能有两种途径：一是节约用水，二是净化废水。后者则被科学家所重视。
当你漫步在被净化的溪水边，看着那又重新恢复清亮的水淙淙流过身边时，当你休憩在被净化的湖边的凉亭下，凝视着碧波荡漾的湖面上鸭鹅嬉戏时，你是否体会到水带给你的享受和乐趣？

People all over the world today are beginning to hear and learn more and more about the problem of pollution. Pollution is caused either by man’s release of completely new and often artificial substances into the environment, or by releasing greatly increased amounts of a natural substance, such as oil from oil tankers into the sea.
The whole industrial process which makes many of the goods and machines we need and use in our daily lives, is bound to create a number of waste products which upset the environmental balance, or the ecological balance as it is also known. Many of these waste products can be prevented or disposed of sensibly, but clearly while more and more new and complex goods are produced there will be new, dangerous wastes to be disposed of, for example, the waste products from nuclear power stations. Many people, therefore, see pollution as only part of a larger and more complex problem, that is, the whole process of industrial production and consumption of goods.
Others again see the problem mainly in connection with agriculture, where new methods are helping farmers grow more and more on their land to feed our ever-increasing populations. However, the land itself if gradually becoming worn out as it is being used, in some cases, too heavily, and artificial fertilizers cannot restore the balance.
Whatever its underlying reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments would make more efforts. In the home there is an obvious need to control litter and waste. Food comes wrapped up three or four times in packages that all have to be disposed of; drinks are increasingly sold in bottles or tins which cannot be reused. This not only causes a litter problem, but also is a great waste of resources, in terms of glass, metals and paper. Advertising has helped this process by persuading many of us not only to buy things we neither want nor need, but also to throw away much of what we do buy.
Pollution and waste combine to be a problem everyone can help to solve by
cutting out unnecessary buying, excess consumption and careless disposal of the products we use in our daily lives.

又至清明扫墓时，每到这时，我总会想起早已逝去的外公，他慈祥的面孔给我留下了太多太多的思念。
小时候，我经常去外公家，因为在我的心目中，外公什么请求都会答应我，所以，幼稚的我把外公家当作我圆“梦”的地方，外公就是那个和蔼慈祥的“圆梦老人”。
爸爸妈妈工作都很忙，我就由外公照顾。5、6岁时，我别提有多听外公话了。外公每天都要忙里忙外，但再忙也不会忘记照顾我。每当外公出去办事，我就会屁颠屁颠地跟在他身后，一刻也不离开。外公也很乐意带我出去，带我去见大世面。每次出去，外公总是卖力地蹬着三轮车，头上渗出滴滴汗珠。每次外公外出回来，总不忘给我带回一些好吃的、好玩的。
记得有一年夏天，我跟随外公出去办事。八月的天气，热得实在叫人受不了，火毒的太阳炙烤着大地。我头上的汗珠地在车上，实在受不了了，我紧皱眉头对外公说：“外公，我要喝水！”外公望了望路两边，面露难色。过了一会儿，外公把车停在了路边，嘱咐道：“你呆在这儿，外公去买水，一会儿就回来。”我点了点头，静静地望着外公远去而又庞大的背影，默默地想：外公真好！
没多久，外公的身影再一次出现在我的眼中，只见他的手中捧着一瓶用湿布包着的冰镇的矿泉水。外公将水递给了我，我忍不住，冲上去，情不自禁的亲了外公一下，外公的脸上满是笑容！
四月，百花齐放。不记得是否与外公一起欣赏过这迷人的春景，不记得曾经是否与外公漫步在美丽的濠河之畔，只知道，现在的我只能一个人欣赏着令人陶醉而又有些伤感的春景。
我永远忘不了那段痛苦的回忆：那一刻，一切的一切都成了定格，所有的悲伤都凝固了，外公永远地闭上了眼睛。我知道，我永远地失去了外公，此时，我不知是无奈还是悲伤。
风呼呼地吹，雨蒙蒙地下，风儿在哀叹，天空在哭泣，蒙蒙细雨中，我仿佛看到外公正面带笑容地望着我。我笑了，心里却流着泪……
