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. 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-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.

Controlling the Ebola virus outbreak at the source in West Africa is the most effective way to decrease international risk of transmission, according to a research paper.
If the epidemic(时疫) persists and grows, it's likely there will be more cases(病例) of the deadly virus exported to other countries, including Canada, via air travel, said Dr. Kamran Khan, a physician and researcher at St. Michael's Hospital.
Dr. Khan, who examines global airline travel patterns to predict the spread of diseases, said that every month, three Ebola-infected travellers are likely to leave West Africa, which is experiencing a widespread outbreak of the virus -- and this number would only increase as the epidemic grows.
Dr. Khan and his co-authors said it is essential that other countries, their public health agencies and hospitals should be prepared. The risk of international spread would be further _____ if this epidemic were to take hold in other countries, especially those with weak public health systems.
"The international community must be mindful and be ready to support the early detection and control of cases." Dr. Khan said.
Dr. Khan noted that of the almost 500,000 travellers who flew on commercial flights out of Guinea, Liberia or Sierra Leone in 2013, more than half were headed to destinations in five countries: Ghana (17.5 per cent, Senegal (14.4 per cent), the United Kingdom (8.7 per cent, France (7.1 per cent) and Gambia (6.8 per cent). More than 60 per cent of travellers from those countries in 2014 are expected to have final destinations in low- or lower-middle income countries.
"Given that these countries have limited medical and public health resources, they may have difficulty quickly identifying and effectively responding to imported Ebola cases”, said Dr Khan.
1.How does Dr. Khan predict the spread of diseases?
A.By doing experiments
B.By examining global airline travel patterns
C. By setting up a model
D. By collecting the data of the cases
2.We can fill in the blank in Paragraph 4 with _____.
A. decreased B. increased
C. avoided D. predicted
3.In low income countries, ______.
A. it is easy to identify imported Ebola cases
B. people have rich medical resources
C. imported Ebola cases may not be effectively responded to
D. travelers are not allowed to go to some places

Are you sometimes stressed? Singing is a simple and effective way to reduce stress. It is beneficial mainly in the following three aspects.
Physical Benefits
1. This is especially recommended for the elders and those who have some form of disability in their voice. However, it is important to find a capable instructor to employ good singing techniques so as not to further damage vocal cords (声带) or lungs.
Singing also helps to improve your posture (姿势). Most people think that singing begins and ends with their mouth. 2. Singing practice will get you used to the proper body position of standing and help you form the good habit of standing straight.
Emotional Benefits
Singing helps in reducing your depression and lowering your stress level. When you sing, your body releases chemicals that make you feel happy, easing the tension and helping you to relax. 3.
Social Benefits
The social benefits of singing are huge. 4. So people who suffer from stage fright are advised to sing in front of family and friends before a live performance.
Singing is also very good for improving your communication skills. It is said that singing to babies helps to prepare their brains for language and may lessen the risk of language problems later in life. 5. The time spent in group singing, whether in a choir or at karaoke, creates a deep and lasting bond of friendship.
A. Try to regain your memory by singing.

Group exercise is one of the most effective ways to improve physical fitness and sustain(保持) a healthy lifestyle. Group exercise is challenging, yet fun and empowering! Of course everyone knows that exercise is good for the body. However, studies have shown that when exercise is performed in groups, it's not only great for improving physical health but for psychological health. It's an opportunity to be social, release endorphins（内啡肽）, and improve your strength. Additionally, group exercise creates a community feel and the shared common goal motivates participants to work hard. The instrumental support of taking on a fitness journey with others proves more effective than going to the gym alone.
Another beneficial aspect of group exercise is the informational support participants receive from the instructor. Many people fear the gym because they feel lost and don't want to embarrass themselves. If you feel you can relate, then group training is an even better option for you. It's a great opportunity to learn more about fitness through the clear instruction and supervision (监管) of a fitness instructor. If you're tired of wandering around the gym wasting time and becoming bored, you can attend an upbeat group fitness class that'll keep your workout on track. Don't let fitness frighten you!
If you're serious about wanting to live a healthy lifestyle, it's extremely important to surround yourself with people who'll provide you with the proper emotional support. I wouldn't scold anyone for deciding to party on weekends and in turn I wouldn't expect anyone to give offence to me for focusing on my health. Surround yourself with people who uplift, encourage and understand you! Make fitness even more fun by trying something new or any group fitness class, with a friend. Plan to go for a jog together. Then try a fun healthy restaurant or fresh juice bar! Fitness can be both fun and social!
Surrounding yourself with people who'll provide you with respect support can be very beneficial while working towards reaching health and fitness goals. First, decide to do it for yourself and work towards staying positive. Then make sure the people you surround yourself with are supportive. Don't let negativity ruin your motivation.
