Water runs downhill from mountaintops to streams to rivers to oceans. But downhill isn’t the only way that water moves .A new study measures how water travels from country to country for human consumption. This flow isn’t the type we usually think about .These scientists looked at the water used to grow and make the products which get shipped from nation to nation as imports or exports. They call this a flow of“virtual water（虚拟水）”.
We typically think about water as the liquid that flows from a tap. However,92％of the water used by people goes into growing crops，according to water researcher Arjen Hoekstra. He recently studied the hidden travels of virtual water used in products made from things like crops and meats .These products are shipped around the world.
For example．consider a sugary soft drink. Hoekstra estimated that to produce one half-liter of the drink requires between 170 and 310litersofthewater—about 95％—is used to grow and process the ingredients(原料).Another 4％goes into the packaging and labeling. In Hoekstra’s calculation, when one country produces a half-liter of soda and sells it abroad，it exports as much virtual water as would fill a large refrigerator．
According to Hoekstra’s new report，dry countries like Israel and Kuwait，both in the Middle East, get the majority of their virtual water from other countries，through imported products. More surprisingly, some wetter countries，like the Netherlands and the United Kingdom, also get the majority of their virtual water from other places. That means that most of the water used to grow or produce the products and food consumed in those countries came from other countries.
In the United States most of the virtual water used comes from American sources .In China even less of the water associated with its products
【小题1】What is the best title for the passage?A．Crops and Virtual WaterB．Import and Export of WaterC．Benefits of Virtual WaterD．Water’s worldwide travels【小题2】The first paragraph is intended to talk about .A．how water flowsB．what virtual water isC．where virtual water exists D．why water is imported and exported【小题3】The example of a sugary soft drink in Paragraph 3 is given to show .A．how drinks are madeB．how virtual water is usedC．how virtual water is exportedD．how drinks are shipped【小题4】In which countries does most part of virtual water come from outside?A．lsrael and AmericaB．America and the NetherlandsC．China and the United KingdomD．Kuwait and the Netherlands【小题5】The passage is most probably a .A．science news reportB．book reviewC．newspaper advertisement D．science fiction storyD

(答案→)D 解析：文章大意：文章主要讲解水是怎么在全世界范围旅行的。【小题1】主旨大意题。根据全文可知，本文是一篇科普类阅读，主要介绍水是怎么在全世界范围旅行的。故D正确。【小题2】推理判断题。根据文章第一段最后一句They call this a flow of“virtual water（虚拟水）可知此段讲解什么是虚拟水。故B正确。【小题3】推理判断题。根据文章第三段，我们可以了解到作者给出实例来解释虚拟水是如何使用的。故B正确。【小题4】细节理解题。根据文章倒数第二段According to Hoekstra’s new report，dry countries like Israel and Kuwait，both in the Middle East, get the majority of their virtual water from other countries，through imported products. More surprisingly, some wetter countries，like the Netherlands and the United Kingdom, also get the majority of their virtual water from other places.可以得出答案。故D正确。【小题5】推理判断题。根据全文可知，本文是一篇科普类阅读。故可以推测出文章可能选自于科学新闻报道。故A正确。
