问题     Throughout the past century humanity did everything in its power to control nature. We dammed earth’s rivers, chopped down the forests and exhausted the soils. Burning up fuels, we pumped a great deal of greenhouse gases into the air, altering the chemistry of the atmosphere and warming the planet in just a few decades. And as our population began in the year 2000 above the 6 billion mark, still spreading across the continents, dozens of animal and plant species were dying out every day, including the first primate(灵长类)to disappear in more than 100 years.
    As the start of the 21st century there were unmistakable signs that nature was beginning to take its revenge. Melting ice in both poles of the earth suggested that the climate was changing rapidly. Weather was even more changeable than usual, giving some places too little rain and others too much. Fires raced across the dried American West last summer, and recent storms spread damages from Britain to China. No specific event could be directly blamed on global warming. Floods and drought will be more frequent and severe. Other sad signs from an overburdened planet include falling grain and fish harvests and fierce competition for scarce water supplies.
    But there were also, in the year 2000, signs of great awareness. Connected by the Internet, hundreds of millions of people gathered for the 30th anniversary of Earth Day. Governments from Washington to Lima took steps to protect the large wild areas from development. Progress was made toward using more renewable energy from the wind and the sun, and new cars that used both gasoline and electricity spotted(显示)fuel-economy statistics.
    The goal for the new century is "sustainable development" . Is that possible? It depends on how well we understand that humanity is part of nature, not lord and master.
Which of the following is true according to the passage?
选项 A、America suffered a lot from fires last summer.
B、The American government tried to stop development.
C、Humanity built many dams in the past century.
D、Dozens of animals and plants will no longer exist in more than 100 years.
答案C
解析 推理判断题。本题可采用排除法得到答案。文章第二段第四句话中“Fires raced across the driedAmerican West…”的American West是“美国西部”的意思，A选项属于偷换概念，应排除：第三段第三句“Governments from Washington…development．”意为“要采取措施保护大型野生区域远离发展的影响”，但并不是停止发展，应排除；D项时态错误，文章第一段最后一句用的是过去时态，说明已经濒临灭绝而不是将要。故选C。
