第28題答案：ix

對應原文：A段：Per capita water usage has been on an upward trend for many years.

答案解析：A段第一句就提到人均用數(shù)量多年來呈現(xiàn)上漲趨勢。后面的內容都在具體描述上漲幅度的數(shù)字，選項中與此符合的只有ix，由此確定其為正確答案。

第29題答案：vi

對應原文：B段：Agriculture consumes about 70%of the world’s fresh water…After agriculture,industry is the second biggest user of water

第30題答案：iv

對應原文：C段：In rich countries,water consumption has gradually been slowed down by price increases and the use of modern technology and recycling.

第31題答案：ii

對應原文：D段：Many experts believe that the best way to counter this trend is to impose water charges based on the real cost of supplies.

答案解析：D段主要講的是，通過經濟手段，即提升用水價格來逆轉目前的趨勢。ii選項economic pricing對應charges，由此確定其為正確答案。

第32題答案：vii

對應原文：E段：One way to cut back on water consumption is simply to prevent leaks.

答案解析：E段開頭提到，減少用水量的一種簡單方法是防止漏水。vii選項中reducing對應prevent和cut，waste對應leaks，由此確定其為正確答案。

第33題答案：viii

對應原文：F段：Interference with the ecosystem can have a severe effect on both local rainfall patterns and water run-off.

答案解析：F段第一句的提示不是很明顯，但第二句明確提到，對生態(tài)系統(tǒng)的干預會對當?shù)亟邓Ｊ胶偷乇韽搅鳟a生重大的影響，即自然資源之間是相互依賴的，由此確定viii為正確答案。

第34題答案：iii

對應原文：G段：In broad terms,it is thought that rainfall zones will shift northwards,adding to the water deficit in Africa,the Middle East and the Mediterranean–a grim prospect indeed.

第35題答案：prosperous

對應原文：A段：As countries industrialize and their citizens become more prosperous,their individual water usage increases rapidly.

答案解析：根據(jù)industrilaized countries定位到A段的第二句，題干中問的是人們變得怎么樣，空前詞become在文章中原詞出現(xiàn)，increasingly對應more，由此確定prosperous為正確答案。

第36題答案：population

對應原文：A段：In the 21st century,the world’s limited supply of renewable fresh water is having to meet demands of both larger total population and increased per capita consumption.

對應原文：E段：One way to cut back on water consumption is simply to prevent leaks.

答案解析：因為上文中已經提到了價格措施，因此看到other ways之后我們直接轉向E段。這一段主要針對漏水問題，很容易確定答案為leaks。

第39題答案：management

對應原文：F段：Another way of conserving water resources involves better management of the environment generally.

答案解析：longer term measure提示我們關注F段，根據(jù)environmental的修飾關系，確定managment為正確答案。

第40題答案：water deficit

對應原文：G段：In broad terms,it is thought that rainfall zones will shift northwards,adding to the water deficit in Africa,the Middle East and the Mediterranean–a grim prospect indeed.
