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 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. Paving parking lots.

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. suggest what we do to save water at home

D. prove what drinking glass is best for us

4.The text is mainly about ________.

A. why paving roads reduces our water

B. how human activity affects our water supply

【解析】

試題分析: 這是一篇關(guān)于用水問題的議論文。告訴我們，盡管大量用水和污染水源使人類用水處于危險境地，但是人類一些小型的活動也對用水問題有著巨大的影響。短文詳細描寫了生活中容易造成浪費的一些用水問題，并提出了相應(yīng)的建議。

1.B C細節(jié)理解題，根據(jù)The more roads and parking lots we pave , the less water can ｆlow into the ground to become groundwater. 可知導(dǎo)致地下水減少的是鋪設(shè)停車場，選B

2.A細節(jié)理解題。根據(jù)第一段good management can help to make sure there is enough water to meet our basic needs及下文描述，可知要滿足我們的用水需求需要很大的努力, 故選A。

3.C細節(jié)理解題。根據(jù)You can take steps to save water in your home. 及本段描述，可知本段主要是針對如何節(jié)水提出建議，選C

4.B主旨大意題。這篇短文主要描述了人類活動與水資源的關(guān)系，告訴我們?nèi)绾蝸砉?jié)約用水。故選B，人類活動如何影響我們的用水供應(yīng)
