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．
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． The most energy﹣efficient models on the market today consume only about one﹣third as much electricity as average ones．
Minimum energy﹣performance standards need to be raised，or introduced in countries that lack them altogether， to push the average unit's performance closer to the standard of the best．
Next，manufactures should stop using damaging refrigerants．One category of these，hydrofluorocarbons， is over 1，000 times worse than carbon dioxide when it comes to trapping heat in the atmosphere． An international deal to phase out these pollutants， called the Kigali amendment， will come into force in 2019． Foot﹣draggers should approve and implement it；America is one country that has not done so．
Last， more could be done to design offices， malls and even cities so they do not need as many air﹣ conditioners in the first place． More buildings should be built with overhanging roofs or balconies for shade，or with natural air﹣circulation． Simply painting roofs white can help keep temperatures down．
Better machines are necessary． But cooling as an overall system needs to be improved if air﹣conditioners is to fulfill its promise to make people healthier，wealthier and wiser， without too high an environmental cost． Providing indoor shelters of air﹣conditioned comfort need not come at the expense of an overheating world．
1.Why does the author think air﹣conditioning is an overlooked industry？

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. The most energy-efficient models on the market today consume only about one-third as much electricity as average ones. Minimum energy-performance standards need to be raised, or introduced in countries that lack them altogether, to push the average unit’s performance closer to the standard of the best.
Next, manufacturers should stop using damaging refrigerants. One category of these, hydrofluorocarbons, is over 1,000 times worse than carbon dioxide when it comes to trapping heat in the atmosphere.

Better machines are necessary. 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.

Tiny microbes(微生物) are at the heart of a new agricultural technique to manage harmful greenhouse gas. Scientists have discovered how microbes can be used to turn carbon dioxide into soil-enriching limestone(石灰石), with the help of a type of tree that grows in tropical areas, such as West Africa.
Researchers have found that when the Iroko tree is grown in dry, acidic soil and treated with a combination of natural fungi(霉菌) and other bacteria, not only does the tree grow well, it also produces the mineral limestone in the soil around its root.
The Iroko tree makes a mineral by combining Ca from the earth with CO2 from the atmosphere. The bacteria then create the conditions under which this mineral turns into limestone. The discovery offers a new way to lock carbon into the soil, keeping it out of the atmosphere. In addition to storing carbon in the trees’ leaves and in the form of limestone, the mineral in the soil makes it more suitable for agriculture.
The discovery could lead to reforestation(重新造林) projects in tropical countries, and help reduce carbon dioxide in the atmosphere in the developing world. It has already been used in West Africa and is being tested in Bolivia, Haiti and India.
The findings were made in a three-year project involving researchers from the Universities of Edinburgh, Granada, Lausanne and Delft University of Technology. The project examined several microbiological methods of locking CO2 as limestone, and the Iroko-bacteria way showed best results. Work was funded by the European Commission under the Future&Emerging Technologies(FET) scheme.
Dr Bryne Ngwenya of the University of Edinburgh’s School of GeoSciences, who led the research, said:“By taking advantage of this natural limestone-producing process, we have a low-tech, safe, readily employed and easily operating way to lock carbon out of the atmosphere, while improving farming conditions in tropical countries.”

B. CO2 can be broken down by natural fungi and bacteria.
C. The more greenhouse gas is, the more active tiny microbes become.
D. Tiny microbes get along well with the Iroko tree in special soil.
3.What does the underlined word “it” in paragraph 3 probably refer to?
A. Carbon dioxide.
B. Carbon.
C. Soil.
D. Limestone.
4.According to the passage, what can we infer?
A. The action of the tiny microbes can increase the oxygen in the earth.
B. Researchers have done the experiment on trees in Africa for three years.
C. Researchers tend to use natural power to solve their problem.
D. West Africa is one of the most polluted areas all over the world.
5.According to the passage, the Iroko-bacteria method .
