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(鋪砌) 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 (洗碗機(jī))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 .

試題分析:

水資源是有限的，不可再生的資源。除了干旱的氣候造成水資源短缺外，人類(lèi)的活動(dòng)在很大程度上也在減少和浪費(fèi)著地下水。在本文中作者分析了幾種使水資源減少的情況，而且提出了幾種在家中節(jié)約用水的方法。

1.細(xì)節(jié)理解題。文章第二段介紹了鋪砌的道路是如何影響地下水的，根據(jù)The more roads and parking lots we pave ,the less water can flow into the ground to become groundwater .可知選A。

2.推理判斷題。文章提到水資源的危機(jī)和干旱問(wèn)題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們節(jié)約用水，由此判斷要想滿足人們用水的需求，需要人們很大的努力，選C。

3.主旨大意題。文章末段首先提出You can take steps to save water in your home，然后從幾個(gè)方面介紹了如何節(jié)水，故本段中心是介紹我們?cè)诩依锶绾巫龅焦?jié)約用水，答案選D。

4.主旨大意題。作者在文章開(kāi)頭介紹過(guò)量用水和往河里亂扔垃圾會(huì)危及到地球水資源，然后又提到but we also affect our water supply in less obvious ways .在下文中從生活中的幾個(gè)方面進(jìn)行介紹，由此判斷文章中心內(nèi)容是關(guān)于人類(lèi)活動(dòng)對(duì)于水資源的影響，選D。
