Question

(2013·高考安徽卷，B)Using too much water or throwingrubbish 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 comes 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 1.5 tons 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)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.

1.Which of the following is most likely to lead to less groundwater?

A．Using river water.

B．Throwing batteries away.

C．Paving parking lots.

D．Throwing rubbish into lakes.

2.What can be inferred from the text?

A．All water shortages are due to human behavior.

B．It takes a lot of effort to meet our water needs.

C．There is much we can do to reduce family size.

D．The average family in America makes proper use of water.

3.The last paragraph is intended to________.

A．show us how to fix leaks at home

B．tell us how to run a dishwasher

C．prove what drinking glass is best for us

D．suggest what we do to save water at home

4.The text is mainly about________.

A．Why paving roads reduces our water

B．how much we depend on water to live

C．why droughts occur more in dry climates

D．how human activity affects our water supply

2.2】解析：選B。推理判斷題。根據(jù)第二段首句“Human activity is not responsible for all water shortages(短缺)．”可排除A項。根據(jù)第三段最后一句“This shows how much we depend on water to live.but there’s a lot we can do to lower the number.”可知D項不正確。本文強調(diào)的是減少用水量，而不是家庭的人數(shù)，故C項錯誤。根據(jù)全文的內(nèi)容可推知，水浪費、水污染和水需求不斷增長，解決水短缺問題需要付出大量的努力。故選B項。

3.3】解析：選D。寫作意圖題。最后一段首句“You can take steps to save water in your home.”為主題句，接下來從四個方面就steps進行了展開，即四個方法或措施。顯然，本段主要是討論我們在家里如何節(jié)約用水。故選D項。

4.4】解析：選D。主旨大意題。本文為議論文，文章開門見山直入主題：...clear ways that humans can put our water supply in danger，but we also affect our water supply in less obvious ways.討論的是人類對于水供應的顯性和隱性影響。第二段首句“Human activity is not responsible for all water shortages(短缺)．”似乎將話題轉(zhuǎn)入自然方面的原因，但接下來的“but in any case，good management can help to make sure there is enough water to meet our basic needs”又將話題轉(zhuǎn)回到人類自身方面——管理。第三段中的“Thinking about the way we use water every day can make a big difference，too.”以及第四段中的“You can take steps to save water in your home.”均指向的是人類行為對于水供應的影響。故選D項。
