We already know the fastest, least expensive way to slow climate change: Use less energy. With a little effort, and not much m oney, most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets. Not long ago, my wife, PJ, and I tried a new diet—not to lose a little wei ght but to answer an annoying question about climate change. Scientists have reported recently that the world is heating up even faster than predicted only a few years ago, and that the consequences could be severe if we don’t keep reducing emissions(排放) of carbon dioxide(CO2) and other greenhouse gases that are trapping heat in our atmosphere.We decided to try an experiment. For one month we recorded our personal emissions of CO2. W e wanted to see how much we could cut back, so we went on a strict die t. The average US household(家庭) produces about 150 pounds of CO2 a day by doing common-place things like turning on air-conditioning or driving cars. That’s more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses. But how much should we try to reduce?For an answer, I checked with Tim Flannery, author of The Weather Makers: How Man Is Changing the Climate and What It Means for Life on Earth. In his book, he had challenged readers to make deep cuts in personal emissions to keep the world from reaching extremely important tipping points, such as the melting(融化) of the ice sheets in Greenland or West Antarctica. “To stay below that point, we need to reduce CO2 emissions by 80 percent, “ he said.Good advice, I thought. I’d opened our bedroom windows to let in the wind. We’d gotten so used to keeping our air-conditioning going around the clock. I’d almost forgotten the windows even opened. We should not let this happen again. It’s time for us to change our habits if necessary.1. Why did the author and his wife try a new diet?A. To take special kinds of food.B. To respond to climate change.C. To lose weight.D. To improve their health.2. The underlin ed words “tipping points” most probably refer to “”.A. freezing pointsB. burning pointsC. melting pointsD. boiling points3. It can be inferred from the passage that .A. it is necessary to keep the air-conditioning on all the timeB. it seems possible for every household to cut emissions of CO2C. the average US household produces about 3, 000 pounds of CO2 a monthD. the average European household produces about 1, 000 pounds of CO2 a month4. Which of the following would be the best title for this passage?A. Saving Energy Starts at HomeB. Changing Our Habits Begins at WorkC. Changing Climate Sounds ReasonableD. Reducing Emissions of CO2 Proves Difficult【参考答案】1-4 BCBA较难题目特训：节能环保类阅读下列四篇短文，从每小题后所给的A,B,C或D四个选项中，选出最佳选项。

The need to feed a growing population is putting much pressure on the world’s supply of water. With 97% of the world’s w ater too salty to be drunk or used in agriculture, the worldwide supply of water needs careful management, especially in agriculture. Although the idea of a water shortage (短缺) seems strange to someone fortunate enough to live in a high rainfall country, many of the world’s agricultural industries experience constant water shortages.Although dams can be built to store water for agricultural use in dry areas and dry seasons, the costs of water redistribution (重新分配) are very high. Not only is there the cost of the engineering itself, but there is also an environmental cost to be considered. Where valleys (山谷) are flooded to create dams, houses are lost and wildlife homes destroyed. Besides, water may flow easily through pipes to fields, but it cannot be transported from one side of the world to the other. Each country must therefore rely on the management of its own water to supply its farming requirements.This is particularly troubling for countries with agricultural industries in areas dependent on irrigation (灌溉). In Texas, farmers’ overuse of irrgation water has resulted in a 25% reduction of the water stores. In the Central Valley area of southwestern USA, a huge water engineering project provided water for farming in dry valleys, but much of the water use has been poorly managed.Saudi Arabia’s attempts to grow wheat in desert areas have seen the pumping o f huge quantities of irrigation water from underground reserves. Because there is no rainfall in these areas, such reserves can only decrease, and it is believed that fifty years of pumping will see them run dry.1. From the first two paragraphs we learn that .A. much of the world’s water is available for useB. people in high ra infall countries feel luckyC. the costs of water redistribution should be consideredD. water can be easily carried through pipes across the world2. Which of the following is true?A. The water stores in Texas have been reduced by 75%.B. Most industries in the world suffer from water shortages.C. The underground water in Saudi Arabia might run out in 50 years.D. Good management of water use resulted from the project in the Central Valley.3. What is most likely to be discussed in the paragraph that follows?A. Steps to improving water use management.B. Ways to reduce the costs of building dams.C. Measures to deal with worldwide water shortages.D. Approaches to handling the pressure on water supply.4. The text is mainly about .A. water supply and increasing populationB. water use management and agricultureC. water redistribution and wildlife protectionD. water shortages and environmental protection【参考答案】1-4 CCAB较难题目特训：节能环保类阅读下列四篇短文，从每小题后所给的A,B,C或D四个选项中，选出最佳选项。
