问题     If you are trying to do your bit for sustainability and save water by taking shorter showers, then a new report on sustainability reveals for the first time that there are more effective ways that our everyday choices can have a positive impact on the environment.
    For example, the glass of juice you have for breakfast might have used the same amount of water in its production as the amount you have just saved by cutting your shower from 10 to 5 minutes. The milk on your cereal might have used even more.
    Balancing Act, a world first that has been developed for the Australia economy by scientists from CSIRO(澳大利亚联邦科学与工业研究组织)and the University of Sydney, looks across 135 industry sectors of the Australian economy and quantifies the impacts and contributions across ten social, environmental, and financial indicators.
    Report co-author CSIRO scientist, Barney Foran, says that sustainability for Australia is a balancing act as we try to make decisions and trade-offs in the face of often-competing economic, social and environmental attributes.
    "We still need to eat and shower—and it is still worth taking shorter showers to save our stressed urban water supplies—but now consumers have a new tool to help us make more informed choices about different types of products based on a new sustainability rating," says Foran.
    Different to other studies because of its detailed observation of the full production chain, this report is able to show the full effects—both direct and indirect—of the production of an individual commodity or service, cappuccinos(卡布奇诺咖啡)or haircuts. It highlights sustainability challenges for different industries and points out areas in the production chain where a focused effort would make a significant difference.
    All effects are referenced back to a consumption dollar—roughly the dollar spent by a consumer in everyday life. It also shows that each consumption dollar is quite different—some dollars are positive and create employment, or suck in imports or generate government revenue. Other consumption dollars are less positive through their high use of water or production of greenhouse gas emissions.
    This relatively simple presentation of highly complex issues makes this a powerful tool for people who are interested in sustainability to move beyond decisions based on dollars and cents and enables them to make decisions based on a contribution to society, environment, and economy.
The new report on sustainability______.
选项 A、suggests that saving water by taking shorter showers is ineffective
B、provides more effective daily ways that can protect environment
C、indicates that drinking juice wastes more water than taking long shower
D、reveals that milk uses more water in its production than juice does
答案B
解析 事实细节题。本题考查新研究报告的意义。首段提到，一份有关可持续性的新报告第一次告诉我们，还有更有效的方式能使我们的生活习惯对环境产生积极的影响，故答案为B)。A)“说明靠缩短淋浴时间节水没什么作用”与原文意思不符，原文只是说有更有效的方法，但并未说靠缩短淋浴时间节水完全没用，故排除；C)“暗示喝果汁比长时间淋浴更浪费水”，原文只是将一杯果汁和5分钟的淋浴所消耗的水量进行对比，但没有说喝果汁就一定比长时间的淋浴更费水，而且该选项中的长时间是个模糊的概念，没用可比性，故排除；D)“表明在生产中牛奶消耗的水比果汁多”，原文使用的是might，不是肯定的语气，故排除。
