　　"900 million people already go hungry and 2 billion people are malnourished in spite of thefact that per capita food production continues to increase," they said. "With 70% of allavailable water being in agriculture, growing more food to feed an additional 2 billion peopleby 2050 will place greater pressure on available water and land. "

　　The report is being released at the start of the annual world water conference inStockholm, Sweden, where 2,500 politicians, UN bodies, non-governmental groups andresearchers from 120 countries meet to address global water supply problems.

　　Competition for water between food production and other uses will intensify pressure onessential resources, the scientists said. "The UN predicts that we must increase foodproduction by 70% by mid-century. This will place additional pressure on our 'alreadystressed water resources, at a time when we also need to allocate more water to satisfy globalenergy demand--　which is expected to rise 60% over the coming 30 years--and to generateelectricity for the 1.3 billion people currently without it," said the report.

　　Overeating, undernourishment and waste are all on the rise and increased food productionmay face future constraints from water scarcity.

　　"We will need a new recipe to feed the world in the future," said the report's editor, AndersJagerskog.

　　A separate report from the International Water Management Institute (IWMI) said the bestway for countries to protect millions of farmers from food insecurity in sub-Saharan Africa andsouth Asia was to help them invest in small pumps and simple technology, rather than todevelop expensive, large-scale irrigation projects.

　　"Farmem across the developing world are increasingly relying on and benefiting from small-scale,locally-relevant water solutions. These techniques could increase yields up to 300% andadd tens of billions of U. S. dollars to household revenues across sub-Saharan Africa and southAsia. " said Dr. Colin Chartres, the director general.

　　61.C)。由题干中的inferred和water scientists’warnin9定位到原文第二段....saying that the world’s population may have to switch almost completely to a vegetarian diet over the next 40 years to avoid atastrophic shortages.

　　详解：推理判断题。本题考查对水资源科学家警示的理解。定位段指出，一些水科学带头人发布了一个关于全球粮食供应的最高级警报，指出为了避免灾难性的粮食紧缺，在未来的四十年，世界人口的饮食可能不得不几乎全转换为素食，故答案为C)。A)“创纪录的干旱使得一半美国人挨饿”，文中第一段指出，这次干旱对大半个美国造成影响，故排除;B)“创纪录的旱灾抬高了美国的食物价格”，文中的is expected t0表示人们的预测而不是事实，故排除;D)“素食成为避免灾害性食物短缺的唯一选择”，文中说的这是一种选择，而不是唯一选择，故排除。

　　62.D)。由题干中的scientists和increase food supply定位到原文第三段第一句：Adopting a vegetarian diet is one option to increase the amount of water available to grow more food in an increasingly climate-unstable world，the scientists said.

　　详解： 事实细节题。本题考查科学家对于增加食物供应量的建议。定位句指出，科学家指出，素食的饮食习惯是在逐渐不稳定的气候条件下增加用来生产更多的食物的可用水资源总量的一种选择，故答案为D)。A)“出产更多富含蛋白质的动物食物”，该段第二句指出动物蛋白质食物要消耗大量的水资源，故不适宜，排除;B)“退牧还耕”，该段第三句指明世界三分之一的耕种土地用于种植喂养动物的食物，即使耕地多也不是多产食物给人们。故排除;C)“增进与自给自足国家间的贸易往来”，该段最后一句指出要让那些粮食有剩余和那些有短缺的国家加强贸易联系，故排除。

　　63.A)。由题干中的the water scientists’report定位到文中第四段第一句：“900 million people already go hungry and 2 billion people are malnourished in spite of the fact that per capita food 　　production continues to increase，”they said.

　　详解：事实细节题。本题考查对水资源科学家研究报告的理解。文中第四段第一句指出，科学家们说： “尽管人均粮食产量在持续增加，但仍有9亿人正在挨饿，20亿人营养不良，故答案为A)。B)“粮食供给量减使更多的人营养不良”，文中说的是人均粮食产量在持续增加，而非减少，故排除;C)“到2050年，70%的水将用来解决20亿人口的饮水问题”.文中指出是给额外的20亿人种植食物，故排除;D)“研究者们开始寻找解决水资源问题的办法”，水资源科学家研究报告中未提及这一点，故排除。

　　64.c)。由题干中的the problem of water supply和scientists believe定位到文中第六段第一句：Competition for water between food production and other uses will intensify pressure on essential esources，the scientists said.和第三句：…at a time when we also need to allocate more water to satisfy global energy demand…

　　详解：观点态度题。本题考查科学家对于水资源供给的态度。文中第六段第一句指出，报告中提到，“联合国预测，到本世纪中叶，我们必须增加70%的粮食产量。这会给本就紧张的水资源造成更大的压力”。第三句指出，“与此同时，我们需要分配更多的水资源来满足世界能源的需求”，故答案为c)。A)“更多的水资源应该分配给能源生产”，这是联合国报告中陈述的一个事实，而不是科学家们的观点，故排除;B)“到本世纪中叶，粮食产量必须增加到70%”，这个目标是联合国制定的而不是水资源科学家所为，故排除;D)“30年后电力资源使用人口将增加60%”，由该段最后一句可知，是增加60%的能源资源而不是使用人口，故排除。
