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？
A. Because many hot countries haven't put the energy﹣controlling rules into force．
B. Because it has caused the same impact on people's life and work as automobiles have．
C. Because it has brought great economic， physical， and educational benefits to humans．
D. Because it doesn't get the due criticism for its environmental impact as automobiles do．
2.What can we learn from Paragraph 4？
A. The price of air﹣conditioning will go up due to the large demand for it．

D. Governments partially agree that air﹣conditioning is a luxury we cannot afford．
3.With regard to the measures to cut the impact of cooling， which of the following statements is TRUE？
A. Manufacturers should only stop using hydrofluorocarbons．
B. People should avoid turning up the air﹣conditioners to have cool rooms on hot days．
C. People should adopt more environmentally﹣friendly materials when designing buildings．
D. Governments should give a green light to the agreement on eliminating the pollutants．
4.The author writes this passage to ．
A. arouse people's attention to the global warming
B. appeal for the global joint efforts to combat global warming
C. give credit to air﹣conditioning for its great contributions to humans
D. offer a new perspective on how to reduce greenhouse gases emissions
Public distrust of scientists stems in part from the blurring of boundaries between science and technology, between discovery and manufacture. Most governments, perhaps all governments, justify public expenditure on scientific research in terms of the economic benefits the scientific enterprise has brought in the past and will bring in the future. Politicians remind their voters of the splendid machines “our scientists” have invented, the new drugs to relieve old disorders, and the new surgical equipment and techniques by which previously unmanageable conditions may now be treated and lives saved. At the same time, the politicians demand of scientists that they tailor their research to “economics needs”, and that they award a higher priority to research proposals that are “near the market” and can be translated into the greatest return on investment in the shortest time. Dependent, as they are, on politicians for much of their funding, scientists have little choice but to comply. Like the rest of us, they are members of a society that rates the creation of wealth as the greatest possible good. Many have reservations, but keep them to themselves in what they perceive as a climate hostile to the pursuit of understanding for its own sake and the idea of an inquiring, creative spirit.
In such circumstances no one should be too hard on people who are suspicious of conflicts of interest. When we learn that the distinguished professor assuring us of the safety of a particular product holds a consultancy with the company making it, we cannot be blamed for wondering whether his fee might conceivably cloud his professional judgment. Even if the professor holds no consultancy with any firm, some people may still distrust him because of his association with those who do, or at least wonder about the source of some of his research funding.
This attitude can have damaging effects. It questions the integrity of individuals working in a profession that prizes intellectual honesty as the supreme virtue, and plays into the hands of those who would like to discredit scientists by representing them as corruptible. This makes it easier to dismiss all scientific pronouncements, but especially those made by the scientists who present themselves as “experts”. The scientist most likely to understand the safety of a nuclear reactor, for example, is a nuclear engineer, and a nuclear engineer is most likely to be employed by the nuclear industry. If a nuclear engineer declares that a reactor is unsafe, we believe him, because clearly it is not to his advantage to lie about it. If he tells us it is safe, on the other hand, we distrust him, because he may well be protecting the employer who pays his salary.

Firstly, I have to express my thanks to you for your reminding, although I don’t agree with your view which students should spend more time on their lessons instead of read novels．Indeed, reading novels takes up some of the time that should spent on lessons, but it’ll make us know what hard life is．Besides, by reading novels we can gain what we can’t learn from our textbook．Of course, reading novels has it’s shortcomings．Novels that have wrong ideas will make us to do something wrong．Maybe, in your eyes, the disadvantages of reading novels outweighs the advantages．And in my opinion, reading novels is just as another pair of eyes, which broadens my horizons．

Do oil and water never mix together? Let’s do an experiment and find it out.
Here 1. what you need. You need a small soft drink bottle, some water, food coloring and two table-spoons of cooking oil.
Now I’ll tell you 2. to do. First, add a few 3. (drop) of food coloring to the water. Then, put about two tablespoons of the colored water along with the two tablespoons of cooking oil 4. the small soft drink bottle. After 5. (do) that, cover the bottle tight and shake it as hard as you can. Finally, put the bottle back down and have a look. It may have seemed as though the liquids were mixing together 6. the oil will float back to the top.
What’s happening? While water often mixes with other liquids, oil and water do not. Water molecules are 7. (strong) attracted to each other. This is 8. same for oil. They are more attracted to 9. (they) own molecules so they just don’t mix. The oil floats above the water because it is 10. (light) than water.
