2．The 21st century coal technology is a major environmental success story that enables society to balanceimportant energy and economic and environmental goals when it achieves the final goal of making coal power emissions-free（ 零排放）．
The numbers tell an amazing story：In the United States，coal-fueled electricity has nearly been three times in step with a doubling of GDP since 1970．During the period，coal's efficiency greatly improved，with key emissions rates per megawatt（兆瓦特） hour decreasing by 89 percent．
The next generation of advanced coal technologies continues to build on this progress．The Prairie State Energy Campus in American's Heartland is a prime example．Prairie State provides electricity for 2.5 million families and is the largest new coal-fueled power plant brought on line，starting up in 2012．It's also among the cleanest coal plants in America． Prairie State has invested 1 billion in control technologies，resulting in emissions rates that are about two-thirds the average of the existing U．S．coal fleet．Even carbon dioxide emissions rates are as much as 25 percent lower thanks to plant efficiencies．A single large plant like Prairie State has the equal environmental benefit of taking one million cars off the road．
Prairie State is a clean source of energy，and it's also an engine for economic strength．Over the next 30 years，Prairie State will contribute more than 22 billion to the local economy．
A study by Management Information Services concludes that by replacing older U．S．coal plants with supercritical （超臨界的） technology，the United States will realize about 1，200 billion increase in economic output，create 6 million jobs，add 500 billion in personal income and an additional 200 billion in tax revenues（稅收）．
The addition of each advanced supercritical plant can help build energy security and provide stable，affordable electricity in the United States and around the world．The future of the technology is bright：569，000 megawatts of supercritical coal plants are in operation or under construction worldwide．In the United States，about half of all new coal-fueled power plants use high-efficiency，low-emissions technologies and this number continues to grow．
32．The major goal of the 21st century coal technology is toA．
A．make coal power emissions-free
B．create as many jobs as possible．
C．promote the economic growth in the U．S．
D．provide more electricity for people．
33．The underlined part in paragraph 3 probably meansC．
A．coming onto the market
B．taking into effect
C．going into operation
D．being under construction．
34．Which of the following is TRUE according to the passage？B
A．Prairie State is the largest power plant in the U．S．
B．More power plants will use supercritical technology in the U．S．
C．Supercritical technology requires financial support from the government．
D．carbon dioxide emissions rates in the U．S．are higher than those in the past．
35．The passage mainly tell readers that the 21st century coal technologyC．
A．originates form the USA．
B．leads to great economic benefits．
C．is an environmental success story．
D．has a bright future of development．
分析 這是一篇說明文，主要介紹了煤炭技術的改進是一個主要的保護環(huán)境的成功故事．
解答 32．A 細節(jié)題．根據文章內容，The 21st century coal technology is a major environmental success story that enables society to balanceimportant energy and economic and environmental goals when it achieves the final goal of making coal power emissions-free（ 零排放）．二十一世紀煤炭技術的最終目的在于使得污染零排放，結合選項，故選A
33．C 詞義猜測題．根據文章內容，The Prairie State Energy Campus in American's Heartland is a prime example．Prairie State provides electricity for 2.5 million families and is the largest new coal-fueled power plant brought on line，starting up in 2012．可知，于2012年啟動的Prairie State 為250萬個家庭提供電力，是現階段運行中的最大的新燃煤發(fā)電廠．結合選項，故選C
34．B 細節(jié)題．根據文章內容，The addition of each advanced supercritical plant can help build energy security and provide stable，affordable electricity in the United States and around the world．由此可知，美國和世界各國都將新建這種工廠，結合選項，故選B
35．C 主旨題．根據文章內容，主要介紹了煤炭技術的改進是一個主要的保護環(huán)境的成功故事．結合選項，故需選C
