【单选题】The passage states that ______.


A．many Americans have switched from hydrocarbon-based fuels to wood because the price of the latter has risen
B．some wood-burning stoves cost up to one hundred times more than others
C．catalytic combustors increase the amount of pollution caused by wood burning stoves
D．agitators are cheaper addition to wood-burning stoves than catalytic combustors


网考网参考答案：B
网考网解析：
A项表示与事实正好相反，C项应是decrease，而不是increase；D项文中并未说明agitators的价格，所以无法比较。而文中第二段括号内的文字(the prices range from $ 50 kits to $5，000 top-of-the-line models)表明炉子价格之差相差100倍，所以B项是正确的。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
