10.Store shelves are filling up with so-called"green"products promising to benefit the environment.A recent argument shows that it can be as difficult for buyers to confirm such statement as for producers to defend them.The argument concerns the GreenPlug Electricity Saver.The GreenPlug is supposed to prevent energy waste by electrical equipment whose constant-speed motors operate at less full load---as is especially true of older refrigerators.Research showed that such motors can be made to do the same work with less heat,noise,and power consumption just by lowering the voltage(电压)of the power supply.
John and Wyck Hay,started Green Technologies to apply that finding to home appliances.In
the USA,there are more than 140million refrigerators in use,accounting for an average of 16% of
the household electric bill.
Two years of research resulted in the GreenPlug.Connecting between wall socket and refrigerator,the equipment contains a minicomputer that gives a motor full power (120volts on average) for start-up,then reduces the power to 106volts.
Older refrigerators are the most overpowered and,thus,save the most energy with a GreenPlug.Refrigerators less than two years old are already energy-saving that a GreenPlug actually makes them waste electricity.
The higher the voltage,the larger the difference a GreenPlug makes.
Higher power costs shorten the payback time.The population-weighted national average is 10cents per kilowatt-hour.But some residents in Washington State pay 1.5cents.Some in Alaska pay 41.6cents.
Then come highly individual household differences like the number of children or refrigerator
-opening age.All in all,the GreenPlug should save the average consumer﹩20a year.
Although the GreenPlug lowered the voltage as it was designed to do,Consumer Reports,an influential magazine,questioned how quickly---if ever---electricity savings due to the plug would repay its cost.People would be better off buying a new,high-efficiency refrigerator,the magazine advised.
Consumer Reports also said that the GreenPlug didn't give a promised 25% savings worth﹩50a year.The savings on the oldest model was the best at 8.6%,worth﹩20a year.
Green Technologies ordered tests of the GreenPlug on up to 2,800refrigerators through next year.The company will not put that data in stores.Instead,potential buyers will call to learn how their model of refrigerator performed.
Meanwhile,there is little evidence of consumer dissatisfaction.Sales topped 45,000units last
month.The return rate is less than 0.2%.
67.The GreenPlug on store shelves are due mostly toA.
A.an increased concern about the environment
B.a demand for money-saving technology
C.the high cost of electrical power
D.the shortage of power supply
68.What do we know about the GreenPlug?C
A.It is especially designed for old refrigerators
B.It works well with all home appliances
C.It can't guarantee lower electric bills
D.It doesn't function with lower voltage
69.In the GreenPlug argument,the magazine Consumer ReportsC.
A.advocates for the GreenPlug
B.suggests Green Technologies never tell the truth
C.doubts the effect of the GreenPlug
D.informs the public of different opinions
70.We can infer from the passage that the authorC.
A.feels optimistic about the future of GreenPlug.
B.believes the GreenPlug has cheated customers.
C.holds an objective attitude to the issue.
D.encourages further investigation.
分析 本文主要讲述作者对绿色节能产品的客观态度.
解答 67.A 68.C 69.C 70.C
67 A 细节题.根据第一段第一句Store shelves are filling up with socalled"green"products promising to benefit the environment.货架上充满了所谓的承诺对环境有益的绿色产品.可知,GreenPlug出现在货架主要是由于人们对环境的关心.故选A. 68 C 推理判断题.根据倒数第四段People would be better off buying a new,highefficiency refrigerator,the magazine advised一份有影响的杂志《消费者报告》建议人们最好还是买个新的高效的冰箱,可推断出此设备并不能保证多大的节能效果.故选C. 69 C 细节题.根据倒数第四段 Consumer Reports,an influential magazine,questioned how quickly-if ever-electricity savings due to the plug would repay its cost.《消费者报告》质疑,如果真能节省电能,需要多久才能抵得上其成本.可知选C. 70 C 推理判断题.作者对绿色节能产品的态度为本题主要考查点.纵观全文,作者列举了著名杂志的观点,并没有表达出自己的想法,所以作者的态度是客观的,故选C.
点评 做阅读理解时要快速的浏览全文,把握文章主旨大意,带着问题回到原文,寻找细节或概括相应的答案,最后要理清作者写作思路.
