Question

The Green Microgym in Portland，Oregon has all the usual stuff you'd expect-sweaty people，loud music，smooth exercise equipment-but it has some extras as well. Everywhere you look，there are power wires. And these aren't the typical kind that let you surf the Web while you ride a spin cycle-although. you can do that too．The gym uses special exercise equipment that captures（捕獲）the energy you create while riding, converts（轉換）it into electricity and channels it into the power outlets（插座）．
The idea of using exercise equipment to produce electricity is not new. A gym in Hong Kong has been doing this since 2007. But clean (and healthy）energy is just now starting to catch on in U. S. gyms·"We have seen a significant increase in interest in the past six months，which is a good sign that fitness centers are ready to spend money on green technologies，” says Mike Curnyn，co-founder of the Green Revolution，a Connecticut-based firm that wires bikes into a central battery that can store energy.
The Green Microgym，first opened in 2008，has more than 200 members and is doing so well that owner Adam Boesel opened another one five miles from the original．Although membership costs about the same as ordinary gyms，customers can earn gift certificates from local businesses for watts produced while exercising．An average workout creates 37. 5 watt hours，which is enough to power a phone for a week．
Boesel uses spin bikes made by Resource Fitness，a Seattle company he co-owns，that captures energy produced from the flywheel. Wires send the converted AC current（交流電流）into any standard wall outlet-for this reason，the product line's name is Plug Out-and the energy created is used before the building draws power from the grid（電網）．Unlike the Green Revolution equipment，Plug Out machines cannot store extra energy. A third company，the Florida-based ReRev，is adding converters to a specific brand of spin bikes. But since the converters add＄1，000 to the price of the equipment，the ReRev and Green Revolution machines are at a disadvantage．
Resource Fitness，by contrast，sells its equipment for the same＄1，200 price as non- electricity-producing machines，removing the question of how long it will be until the energy savings pay for the cost of the unit．The company can afford to do this because its designs don’t call for the extra wiring needed for battery packs and large converters．It is also trying to price competitively with standard equipment so more gyms-and gym goers-will make the switch．

試題分析：
【文章大意】本文是一篇說明文。文章主要介紹了Resource Fitness公司生產的人力轉化成電能的健身產品。
小題1:A考查細節(jié)理解。根據文章中的Although membership costs about the same as ordinary gyms，customers can earn gift certificates from local businesses for watts produced while exercising.和Boesel uses spin bikes made by Resource Fitness，a Seattle company he co-owns，that captures energy produced from the flywheel.可知，健身者在鍛煉的過程中，通過輪子的旋轉產生能量。即是把人力轉化成了電能。故選A。
小題2:D考查細節(jié)理解。根據文章中的Unlike the Green Revolution equipment，Plug Out machines cannot store extra energy.可知，Resource Fitness公司生產的旋轉自行車不能儲電是它不同于Green Revolution公司產品的地方。故選D。
小題3:B考查推理判斷。根據文章最后兩段Resource Fitness，by contrast，sells its equipment for the same＄1，200 price as non-electricity-producing machines，removing the question of how long it will be until the energy
savings pay for the cost of the unit．可知，這比其他產品的價格要高200多美元。故選B。
小題4:B考查猜測詞義。根據文章的最后一句話It is also trying to price competitively with standard equipment so more gyms-and gym Boers-will make the switch.可知，Resource Fitness正在設法和標準設備競爭價錢，所以越來越多的健身者選擇綠色環(huán)保健身設備。故選B。
