英语翻译
求翻译,
Using too much water or throwing rubbish into our rivers are clear ways that humans can
Put our water supply in danger ,but we also affect our water supply in less obvious ways .
You may wonder how paving(铺砌) a road can lead to less useable fresh water .A major
Part of the water we use every day is groundwater .Groundwater does not come from lakes or rivers .It come from underground .The more roads and parking lots we pave ,the less water can
Flow into the ground to become groundwater .
Human activity is not responsible for all water shortages(短缺).Driver climates are of course more likely to have droughts(干旱) than areas with more rainfall ,but in any case,good management can help to make sure there is enough water to meet our basic needs .
Thinking about the way we use water every day can make a big difference ,too In the United States ,a family of four can use 1.5tons of water a day This shows how much we depend on water to live ,but there’s a lot we can do to lower the number .
You can take steps to save water in your home .To start with ,use the same glass for your drinking water all day .Wash it only once a day .Run your dishwasher (洗碗机)only when it is full .Help your parents fix any leaks in your home .You can even help to keep our water supply clean by recycling batteries instead of throwing them away .

过量用水,乱扔垃圾入河是人类破坏水供应的明显方式,而我们也会用些不太明显的方式影响水质.你可能会问,铺路怎么会导致可用的净水变少.其实我们每天所用的绝大部分水是地下水.地下水不是来源于湖泊或河流,而是来源于地表以下.我们修建的道路及停车场越多,那么能渗透地面成为地下水的水就越少.
不是所有的水资源短缺都是由人类活动导致的.干燥气候地区当然比降雨量多的地区更容易出现干旱,但是不管怎样,良好的管理可有助于确保持有足够的水资源以满足我们的基本需求.
光想一想我们每天用水的方式也能产生大作用.在美国,一个四口之家一天要用掉1.5吨水.这表明了我们生存得用掉多少水,然而我们可以做很多事来降低这个数字.
你可以在家里开始节约用水的步骤.首先,全天只用同一个杯子喝水,一天只洗一次.只在洗碗机满了的时候再打开它开始洗.帮助父母修好家里的任何漏水的地方.你甚至可以通过回收电池而不是把它们丢掉来帮助保持我们清洁的水供应系统.
基础意思就是这样..(话说洗碗机在美国普及了啊,真是长姿势了.)
再问： 还有一小段，能不能帮翻译了，谢谢，2012陕西卷，最后一段。http://zhidao.baidu.com/question/1302966324802980619.html?quesup2&oldq=1
