SAT寫作經典例子之水污染
下面為大家整理的是一篇關于水污染的SAT寫作例子。這篇例子的主要內容是記述了一些有識之士自發保護美國河流免受污染的故事。下面我們一起來看看這篇SAT寫作例子的詳細內容吧。
Insightful Men Voluntarily Protect American Rivers From Pollution
James Holland calls himself the eyes and ears of the Altamaha River. The 220 kilometer river he watches is relatively undisturbed by channels, dredging or major reservoirs. Its swamps and refuges are home to dozens of rare or endangered plants and animals including some found nowhere else on earth.
James Holland has spent a lifetime on the river as a crab fisherman, but blames the decline of fisheries, and the failure of his business, on poor water quality. Now as an advocate for the Altamaha, the 60 year old retired crabber responds to reports of erosion, loss of wetlands, and the illegal dumping of pollutants from agriculture and industry. I view it as my job to end pollution where I see it, when I see it, said James Holland
James Holland finds garbage stashed in tree trunks and pools of diesel fuel and abandoned trucks at logging operations near the river. A recent complaint on hog waste from a processing plant in the watershed led him to take a closer look. In doing so I found the County making preparations for paving a road, he said. They were widening it and making improvements. And, in doing so they destroyed wetlands. They didnt have enough erosion control to prevent erosion. I went further on from the spray field and from the area where I could view the spray field, the guy up there was draining wetlands. I found a ditch where he was draining wetlands. I also found right there standing in one spot where he destroyed two wetlands in the last two or three years. Its just a whole hot of things. Its unreal is what it is.
While James Holland leads the fight for the Altamaha, he isnt alone. Altamaha Riverkeeper Executive Director Deborah Sheppard says the group has inspired an increasing number of citizen volunteers. And I know were making a difference because every day people communicate with us about problems that would not have been addressed if they hadnt talked to us, said Deborah Sheppard. And thats probably one of the best things that the River keeper movement has done around the country is begin the process of helping people understand that if we have a law in place to protect the environment, we all have a responsibility to help it be enforced.
Riverkeeper James Holland agrees. He sees the Altamaha differently from his days as a crab fisherman. He says he doesnt think anymore what he can take from the river, but what he can give back.
水污染的原因
人類生產活動造成的水體污染中，工業引起的水體污染最嚴重。如：工業廢水，它含污染物多，成分復雜，不僅在水中不易凈化，而且處理也比較困難。
工業廢水，是工業污染引起水體污染的最重要的原因。它占工業排出的污染物的大部分。工業廢水所含的污染物因工廠種類不同而千差萬別，即使是同類工廠，生產過程不同，其所含污染物的質和量也不一樣。工業除了排出的廢水直接注入水體引起污染外，固體廢物和廢氣也會污染水體。。。。。。
農業污染首先是由于耕作或開荒使土地表面疏松，在土壤和地形還未穩定時降雨，大量泥沙流入水中，增加水中的懸浮物。
還有一個重要原因是近年來農藥、化肥的使用量日益增多，而使用的農藥和化肥只有少量附著或被吸收，其余絕大部分殘留在土壤和漂浮在大氣中，通過降雨，經過地表徑流的沖刷進入地表水和滲入地表水形成污染。
城市污染源是因城市人口集中，城市生活污水、垃圾和廢氣引起水體污染造成的。城市污染源對水體的污染主要是生活污水，它是人們日常生活中產生的各種污水的混合液，其中包括廚房、洗滌房、浴室和廁所排出的污水。
世界上僅城市地區一年排出的工業和生活廢水就多達500立方公里，而每一滴污水將污染數倍乃至數十倍的水體。
措施與建議
1. 強化對飲用水源取水口的保護：
有關部門要劃定水源區，在區內設置告示牌并加強取水口的綠化工作。定期組織人員進行檢查。從根本杜絕污染，達到標本兼治的目的。
2. 加大城市污水和工業廢水的治理力度：
加快城市污水處理廠的建設對于改善我市水環境狀況有著十分重要的作用。目前隨著城市人口的增加和居民生活水平的提高，我市的廢水排放量正在不斷地增加，而城市污水處理廠卻沒有相應地增加，這必然會導致水環境質量的下降。因此建設更多的污水處理廠是迫在眉睫的事。
3. 加強公民的環保意識：
改善環境不僅要對其進行治理，更重要的是通過各方面的宣傳來增強居民的環保意識。居民的環保意識增強了。破壞環境的行為就自然減少了。
4. 實現廢水資源化利用：
隨著經濟的發展，工業的廢水排放量還要增加，如果只重視末端治理，很難達到改善目前水污染狀況目的，所以我們要實現廢水資源化利用。
5.家用水的凈化：
過濾沉淀用活性炭除異味，去顏色消毒。在自來水管傳遞過程中有可能出現二次污染，所以飲用時要煮沸殺菌，而且還要用干凈的杯子。
另：有條件的家庭可以安裝家用健康飲水機
6.強化青少年保護水資源意識：
對于青少年，普遍的家庭并不太注重保護水資源的教育。教育要從小做起，養成保護水資源的意識，畢竟教育要從娃娃抓起。加強對青少年保護水資源的教育，拍宣傳片、做宣傳活動，讓中國未來的每一朵花都有節約的好品德、保護水資源。以后，大量污染水資源問題就會漸漸減小。
7.少量創建填埋場：
可少量創建填埋場，讓廢水廢氣都能夠經過處理，再排放至河流。由于填埋場占地面積大，浪費土地資源，所以應少量創建。
以上就是關于SAT寫作例子中水污染方面的相關信息，包括了英語和漢語兩個部分，英語的是故事，漢語介紹了一些相關的背景知識。大家可以在練習SAT寫作題目中相關話題的時候，對此加以適當的應用。
