Question

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 came 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). Drier 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 .

试题分析:

水资源是有限的，不可再生的资源。除了干旱的气候造成水资源短缺外，人类的活动在很大程度上也在减少和浪费着地下水。在本文中作者分析了几种使水资源减少的情况，而且提出了几种在家中节约用水的方法。

1.细节理解题。文章第二段介绍了铺砌的道路是如何影响地下水的，根据The more roads and parking lots we pave ,the less water can flow into the ground to become groundwater .可知选A。

2.推理判断题。文章提到水资源的危机和干旱问题Using too much water ……are clear ways that humans can put our water supply in danger,和 Drier climates are of course more likely to have droughts而且在文中也提倡人们节约用水，由此判断要想满足人们用水的需求，需要人们很大的努力，选C。

3.主旨大意题。文章末段首先提出You can take steps to save water in your home，然后从几个方面介绍了如何节水，故本段中心是介绍我们在家里如何做到节约用水，答案选D。

4.主旨大意题。作者在文章开头介绍过量用水和往河里乱扔垃圾会危及到地球水资源，然后又提到but we also affect our water supply in less obvious ways .在下文中从生活中的几个方面进行介绍，由此判断文章中心内容是关于人类活动对于水资源的影响，选D。
