As the proverb goes, man struggles upwards阅读理解答案
阅读理解As the proverb goes, man struggles upwards; water flows downwards. Water runs downhill from mountaintops to streams, to rivers and 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”.
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 a 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 310 liters of water—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.
25. The proverb in Paragraph One is used to_________.
A. inspire readers to struggle upward B. tell a law of nature
C. introduce the topic of the passage D. summarize the main idea of the passage
26. In which countries does most part of virtual water come from outside .
A. The United Kingdom and China B. America and Israel
C. The Netherlands and Kuwait D. The Netherlands and America
27. What can be a suitable title for the passage
A. Benefits of Virtual Water B. Hidden Uses of Water
C. Crops and Virtual Water D. Water’s Worldwide Travels
28. Where does the passage probably come from
A .A science news report. B. A newspaper advertisement.
C. A book review. D. A science fiction story.
答案解析：
C CDA
