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 .

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

 

The behaviour of a building’s users may be at least as important as its design when it comes to energy use, according to new research from the UK Energy Research Centre (UKERC). The UK promises to reduce its carbon emissions (排放)by 80 percent by 2050, part of which will be achieved by all new homes being zero-carbon by 2016. But this report shows that sustainable building design on its own — though extremely important- is not enough to achieve such reductions: the behaviour of the people using the building has to change too.

The study suggests that the ways that people use and live in their homes have been largely ignored by existing efforts to improve energy efficiency (效率),which instead focus on architectural and technological developments.

‘Technology is going to assist but it is not going to do everything,’explains Katy Janda, a UKERC senior researcher,‘consumption patterns of building users can defeat the most careful design. ’In other words,old habits die hard, even in the best-designed eco-home.

Another part of the problem is information. Households and bill-payers don’t have the knowledge they need to change their energy-use habits. Without specific information,it’s hard to estimate the costs and benefits of making different choices. Feedback (反馈) facilities, like smart meters and energy monitors,could help bridge this information gap by helping people see how changing their behaviour directly affects their energy use; some studies have shown that households can achieve up to 15 percent energy savings using smart meters.

Social science research has added a further dimension (方面),suggesting that individuals’behaviour in the home can be personal and cannot be predicted 一 whether people throw open their windows rather than turn down the thermostat (恒温器) , for example. Janda argues that education is the key. She calls for a focused programme to teach people about buildings and their own behaviour in them.
