What is the single most effective way to reduce greenhouse﹣gas emissions？ Go vegetarian？ Replant the Amazon？ Cycle to work？ None of the above． The answer is： make air﹣conditioners radically better． On one calculation，　 replacing　 refrigerants（制冷剂）　 that　 damage　 the　 atmosphere　 would　 reduce　 total　 greenhouse gases by the equivalent of 90bn tons of CO2 by 2050． Making the units more energy﹣efficient could double that．

Air﹣conditioning is one of the world's great overlooked industries． Automobiles and air﹣conditioners were invented at roughly the same time， and both have had a huge impact on where people live and work．

Unlike cars， though， air﹣conditioners have drawn little criticism for their social impact， emissions or energy efficiency． Most hot countries do not have rules to govern their energy use．

Yet air﹣conditioning has done quite a lot of things to benefit humankind． It has transformed productivity in the tropics and helped turn southern China into the workshop of the world． In Europe，its spread has pushed down heat﹣related deaths ten times less than what it was in 2003， when around 70，000 people， most of them elderly， died in a heatwave． For children， air﹣conditioned classrooms and dormitories are associated with better grades at school．

Environmentalists who call air﹣conditioning "a luxury we cannot afford" have half a point， however．

What is the single most effective way to reduce greenhouse-gas emissions? Go vegetarian? Replant the Amazon? Cycle to work? None of the above. The answer is: make air-conditioners radically better. On one calculation, replacing refrigerants(制冷剂) that damage the atmosphere would reduce total greenhouse gases by the equivalent of 90bn tonnes of CO2 by 2050. Making the units more energy-efficient could double that.

Air-conditioning is one of the world’s great overlooked industries. Automobiles and air-conditioners were invented at roughly the same time, and both have had a huge impact on where people live and work. Unlike cars, though, air-conditioners have drawn little criticism for their social impact, emissions or energy efficiency. Most hot countries do not have rules to govern their energy use.

Yet air-conditioning has done quite a lot things to benefit humankind. It has transformed productivity in the tropics and helped turn southern China into the workshop of the world. In Europe, its spread has pushed down heat-related deaths ten times less than what it was in 2003, when 70,000 people, most of them elderly, died in a heatwave. For children, air-conditioned classrooms and dormitories are associated with better grades at school.

Environmentalists who call air-conditioning “a luxury we cannot afford” have half a point, however. In the next ten years, as many air-conditioners will be installed around the world as were put in between 1902 (when air-conditioning was invented) and 2005. Until energy can be produced without carbon emissions, these extra machines will warm the world. At the moment, therefore, air-conditioners create a vicious cycle. The more the earth warms, the more people need them. But the more there are, the warmer the world will be.

Cutting the impact of cooling requires three things (beyond turning up the thermostat(温度调节器) to make rooms less Arctic). First, air-conditioners must become much more efficient.

But cooling as an overall system needs to be improved if air-conditioning is to fulfil its promise to make people healthier, wealthier and wiser, without too high an environmental cost. Providing indoor sanctuaries of air-conditioned comfort need not come at the expense of an overheating world.

高三英语单项填空中等难度题查看答案及解析

The U.S. government’s push to decrease the nation’s output of greenhouse gases by increasing the fuel efficiency of the cars Americans drive is arousing again an emotional argument Does driving a small, fuel-efficient car make you more likely to die on the road?

Engineers and statistical analysts can point to data that suggest more-efficient cars don’t necessarily put motorists at greater overall risk. But most of us care less about the “overall” risk than we do about ourselves. Driving a big Chevrolet Tahoe SUV makes many of us believe we are safer than we would be in a smaller car — even if statistical measures across a large population of vehicles and all kinds of car accidents suggest the advantage of safety isn’t quite as wide as SUV owners believe.

The Obama government has put the fuel-efficiency and safety question back on the front burner by calling for new-vehicle fuel economy to rise to an average of 35 miles per gallon （加仑） by 2020 from about 25 mpg today. That goal could move higher if the government decides to adopt California’s requirement to cut vehicle greenhouse-gas giving off, which would result in stricter mileage standards.

Those moves, and the effects of last summer’s gas-price shock, are driving auto makers to offer cars such as the Toyota Yaris, Honda Fit and Daimler AG’s Smart For Two — which get the kind of mileage today that law says should be the average in a decade. Beyond that, auto makers will launch a wide range of new compact （紧凑的） vehicles, and decrease production of large, body-on-frame SUVs.

That’s leading to new concerns about “green safety”, a term for managing the balance between reducing vehicle size for efficiency and adding safety and protection features that tend to make vehicles heavier and less efficient. Undoubtedly, further work has to be done before Americans make the choice.

1.The U.S. government requires to improve the fuel efficiency in order to ________.

A．push Americans to drive smaller cars

B．reduce the output of greenhouse gases

C．drive auto makers to produce fewer SUVs

D．cause Americans to make an argument

2.According to Paragraph 2, engineers and analysts’ idea ________.

A．fails to relieve people of their worry about safety

B．persuades people to purchase smaller cars instead of SUVs

C．is based on research and therefore persuasive enough

D．makes people think of their safety as well as others’

3.About the Obama government’s new moves, the auto makers are ________ and average　 Americans are ________.

A．uncertain; positive　　　　 B．doubtful; uncertain

C．supportive; positive　　 D．positive; uncertain

4.The best title for the text should be ________.

A．New Law Reduces Greenhouse Gases Output

B．Can Small Cars Overcome Accident Fears?

C．New Compact Cars Gets Popular in the U.S.

D．Do We Have to Follow the Government?
