每天跑步7分钟可延长3年寿命
Here’s a question: If you could extend your life 3 years, just by running 7 minutes a day - would you do it?
现在问大家一个问题：如果你每天只需跑7分钟就可以延长3年的寿命，你是否会这样做？
Hey guys, Tara here for Dnews - and I’ll admit it: I’m not a runner. I tried to run a half-marathon back in 2008, but then I injured my knee and it all went to hell. So imagine my surprise, when a new study pops up this week in the Journal of the American College of Cardiology - that says you don’t have to go the distance, to reap the benefits of running. Turns out, all it takes - is 7 minutes a day!
大家好，Tara为您播报D新闻——我必须承认，我不喜欢跑步。2008年，我曾经尝试参加马拉松比赛，只跑了一半，但是后来膝盖受伤，就不了了之。所以，你就能理解当我听到这个消息的时候会感到多么惊讶了：美国心脏病学会杂志一项新研究称，要从跑步中获益，你不需要跑得太远。事实证明，每天只需要跑7分钟就可以了。
The article shares the results of a 15-year-long cohort study of over 55,000 adults, to see whether running could reduce someone’s risk of death from anything - not just heart disease.
这篇研究分享的是对超过5.5万名成年人进行了长达15年的研究得出的结果，查看跑步是否可以降低任何疾病造成的死亡风险——不仅仅是心脏病。
Now because it is a cohort study, it can’t technically conclude that running is what causes the reduced risk of death - but the correlation is there, and it paints a pretty clear picture. People who run, even in modest amounts, of 51 minutes a week - were found to have a 45% reduction in the risk of cardiovascular-related death, and a 30% overall reduction in any type of death, compared to non-runners. This means that, on average, running can increase someone’s life expectancy by about three years.
现在，因为这是群组研究，从学术上将不能得出结论跑步是否死亡风险降低的原因——但是两者之间确实有关联，这项研究描绘出了非常清晰的图画。即使跑步量很小的人，每周51分钟，心血管疾病导致的死亡风险也可以降低45%，任何类似的死亡风险可以降低30%。这意味着，平均来说，跑步让人的寿命增加3年。
Now 51 minutes a week, or about 7 minutes a day - isn’t exactly a tall order. But the study also took other factors into account - like distance, and speed - and found that even they don’t make much of a difference at all. Even a light jog can significantly reduce one’s mortality risk. Although they did find that persistent runners - people who do it regularly - had the best outcomes,with an average 50% reduction in cardiovascular-related deaths, and 29% reduction in overall mortality.
每周51分钟，或者每天7分钟，并不是多么难以达到的目标。但是这项研究还将其他因素考虑在内——比如距离和速度——他们发现，这些因素并不是多么重要。即使慢跑也可以显著降低死亡率。然而他们确实发现持续跑步者——经常跑步的人获得的效果最好，心血管相关疾病导致的死亡率可以降低50%，总体死亡率降低29%。
Pretty impressive. Although it is worth noting that while certain things were adjusted for - like age, smoking, alcohol consumption,and family history of heart disease - diet was not adjusted for, which can have a pretty big influence on someone’s health status.
这是令人印象非常深刻的数字。值得注意的是，必须根据一些因素进行调整，比如年龄，吸烟，喝酒和家庭心脏病史，然而并没有将饮食因素考虑在内——这对一个人的健康状况有着非常显著的影响。
Researchers also note that while it is a big study, most of the people who participated were white, middle-to-upper class adults. So it’s not totally clear how their results apply to other populations.
研究人员还指出，尽管这是一项非常大型的研究，然而参加研究的人大部分是白人，中产阶级或上流社会成年人。所以研究结果是否适用其他阶层不是那么明确。
In any case, it’s still promising to know that even the most minimal amount of exercise can have positive effects on your health. And hopefully, that’ll encourage some of us - myself included - to not be so intimidated by the thought of working out. I’m sure all of us out there would agree that 7 minutes a day - is something we can all make time for.
无论如何，即使最少量的运动也可以对你的健康产生非常积极的影响。这也鼓励包括我在内的一些人不要过多地考虑锻炼的结果。我确信所有人都赞同，每天7分钟的时间我们肯定都能抽的出来。

Winds finally blow away thick smog
北方大风吹走雾霾
Residents in many parts of Northern and eastern China finally caught a breath of fresh air on Wednesday, after almost a week of heavy smog in these pollution-prone parts of the country. And the air quality here in the Chinese capital got so bad, that authorities issued an orange alert, putting in place emergency measures to cope with the smog. Now to give you a better picture of just how severe the air pollution was. These are satellite images snapped by US space agency NASA on November the 30th. You can see a "smog belt" extending from the Chinese capital all the way to the province of Shaanxi. This round of smog began late last week and was at its worst at the beginning of this week.
A celebratory mood on Weibo on Wednesday after overnight winds blew back fresh air for many millions of residents in Northern China.
The Chinese capital looked a far cry from just the day before when you couldn't separate day from night, and the city's many landmarks were barely visible.
"This smog makes it hard to see, it's really easy for accidents to happen. Today I didn't drive but as soon as I came out my throat felt uncomfortable, so I'm wearing a mask."
"In the past the air was so clear, you could see the clouds, so clear, but nowadays when can you see a clear sky or white clouds? Never. The air is truly horrible."
Residents coped however they could. Many wore masks, a few avoided the outdoors completely while some vented on the internet.
This set of pictures, or rather doodles have gone viral since. Beijing's landmark architecture fading beneath the shroud, brought back with artistic license.
And one netizen even took the time and effort to document how the Chinese capital went from filthy to clean in less than 5 hours.
But jokes aside, the public is also demanding answers.
"It's the result of a combination of local pollution, transferred pollution and unfavourable weather conditions. The pollution was caused by coal burning and industrial emissions while the atmospheric condition made it impossible for the pollution to dissipate," Professor Wang Zifa with Chinese Academy of Sciences said.
Many are also pointing the finger at the city's response measures, or, the lack of. An orange alert was issued by the Beijing government. Some factories were shut down, construction halted and schools paused outdoor activities.
"We believe that the orange alert is in line with the Heavy Air Pollution Contingency Plan . But the problem is that we saw heavy pollution for more than three consecutive days, without a red alert issued in advance accordingly. So we believe this contingency plan is in fact inadequate," Dong Liansai, climate & energy campaigner of Greenpeace, said.
For now, residents in the pollution prone regions of China are enjoying a reprieve. But there is one question hanging on the minds of the public, when will fresh air again be the norm and not a luxury.

As part of the effort to reduce carbon emissions, the Chinese government is now encouraging the appearance of more new energy vehicles on the roads. Our reporter Meng Qingsheng visited a major electric cars manufacturer in Beijing, and talked with one of their top engineers on the outlook for the industry.
Driving the low-carbon way. China has decided to put five million new energy vehicles on the roads by 2020. That will take up nearly one-third of the country’s total amount of cars.
Established in 2009, Beijing Electric Vehicle Company is taking the lead to fulfil this mission. It has brought to the market five pure electric car models.
This model of new energy cars has seen rising demand since it entered the market last year. It features hi-tech interior design, smog filtering system, and of course, a long-enduring battery that can go the distance.
The battery that EV200 employs can sustain a distance of 260 kilometers, equivalent to a round trip from the capital to neighboring Tianjin city.
The manufacturer aims to achieve an annual production of 200-thousand cars by 2020, ten times higher than the current capacity.
This requires more charging facilities to be built nationwide.
"We did go through hardships in the beginning. The lack of charging facilities affected our businesses. Our company set up a special team to expand the facility services. We provide free charging facilities for individual customers, while cooperating with other companies to build more public services," Hu Wei, chief engineer with Beijing Electric Vehicle Company, said.
The company is now going further by introducing a self-developed alternating- and direct-current converter.
This technology allows the car’s battery to support other vehicles, as well as home appliances.
It’s part of the V-to-G system that returns electricity to the grid.
"The electric cars are connected with the grid. Therefore, it's important to have electric load management. A vehicle uses its excess battery capacity to provide power to the electric grid in response to peak load demands. These vehicles can then be recharged during off-peak hours," Hu said.
The fleet of new energy vehicles in China is the second largest in the world after the United States.
China has rolled out a set of measures to further promote the industry’s development.
This move not only contributes to global efforts to fight climate change, but also helps spreads a low-carbon lifestyle in the world's most populated country.
