剑桥雅思6 G类TestA Section3阅读答案解析The water crisis

第28题答案：ix

对应原文：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数量多年来呈现上涨趋势。后面的内容都在具体描述上涨幅度的数字，选项中与此符合的只有ix，由此确定其为正确答案。

第29题答案：vi

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

答案解析：B段可以明显分为两部分，前半段描述农业对淡水资源的需求，后半段描述工业对淡水资源的需求。vi选项中sectors对应agriculture和industry，thirsty对应水资源的需求，由此确定其为正确答案。

第30题答案：iv

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

答案解析：C段开头提到，在一些富裕国家，通过提升价格，使用现代科技和进行回收，水资源的消耗速度变慢了。随后又用美国、日本和德国的例子来说明这一点。即一些国家所采取的成功措施，由此确定iv为正确答案。

第31题答案：ii

对应原文：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段主要讲的是，通过经济手段，即提升用水价格来逆转目前的趋势。ii选项economic pricing对应charges，由此确定其为正确答案。

第32题答案：vii

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

答案解析：E段开头提到，减少用水量的一种简单方法是防止漏水。vii选项中reducing对应prevent和cut，waste对应leaks，由此确定其为正确答案。

第33题答案：viii

对应原文：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显，但第二句明确提到，对生态系统的干预会对当地降水模式和地表径流产生重大的影响，即自然资源之间是相互依赖的，由此确定viii为正确答案。

第34题答案：iii

对应原文：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.

答案解析：G段的大部分都在对未来进行推测，但促使我们选ii的最重要原因还是最后一句中的prospect一词。

第35题答案：prosperous

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

答案解析：根据industrilaized countries定位到A段的第二句，题干中问的是人们变得怎么样，空前词become在文章中原词出现，increasingly对应more，由此确定prosperous为正确答案。

第36题答案：population

对应原文：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.

答案解析：顺着上一题往下，空前词bigger对应larger，global对应total，根据修饰关系，确定population为正确答案。

第37题答案：(modern)technology

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

答案解析：根据rich countries定位到C段的第一句，由并列关系确定modern technology为正确答案。

第38题答案：leaks

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

答案解析：因为上文中已经提到了价格措施，因此看到other ways之后我们直接转向E段。这一段主要针对漏水问题，很容易确定答案为leaks。

第39题答案：management

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

答案解析：longer term measure提示我们关注F段，根据environmental的修饰关系，确定managment为正确答案。

第40题答案：water deficit

对应原文：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.

答案解析：根据many countries与各个国家的对应定位到G段的倒数第二句，空前词worsen与adding to对应，由此确定答案为water deficit。
