The spread of Westem eating habits around the world is bad for human nealth and the environment.These findings come from a new report in the journal Nature.
David Tillman, a professor of ecology at the University of Minnesota, America, examined information from 100 countries to identify what people ate and how diet affected health. He noted a movement beginning in the 1960s. He found that as nations mdustriaHzed(工业化),population increased and earnings rose, more people began to adopt what has been called the Western diet.
The Western diet is high in sugar, fat, oil and meat. By eating these foods, people began to get fatter and sicker. David Tillman says overweight people are at greater risk for non-infectious diseases like diabetes (糖尿病）and heart disease.
Unfortunately, when people become industrialized, if they adopt this Western diet, they are going to have these health problems, especially in developing countries in Asia, China is an example where the number of diabetes cases has been jumping from less than one percent to 10 percent of the population as they began to industrialize over a 20，year period, And that is happening all across the world, in Mexico in Nigeria and so on.
And, a diet bad for human beings, is also bad for the environment As the world's population grows, more forests and tropical (热带的）areas will become farmland for crops or grasslands for cattle. We are likely to have more greenhouse gas in the future from agriculture than that coming out of all froms of transportation right now.
Mr．Tillman calls the link between diet，the environment and human health，"a dilemma"，a problem offering a difficult choice. He says one possibte setttemenf is leaving the behind.

Some of the best museums across China are putting their exhibitions online in VR format for free. While stuck at home due to the novel coronavirus outbreak, why not take a detailed online tour at museums that you would not otherwise have time for?
The Palace Museum
The Palace Museum is known as the Forbidden City. Although the museum is now closed due to the current epidemic prevention, it's possible for visitors to take a virtual tour of parts of the museum without actually setting foot on the majestic grounds.
Visitors can browse all the buildings of the Palace Museums. More than 400,000 imperial artifacts have been digitized online, which can definitely help you gain knowledge and immerse yourself in a cultural atmosphere.

Shanghai Museum
Shanghai Museum is a large and famous museum, which collects over 120,000 precious artistic relics from more than 5,000 years ago to the Qing Dynasty. The marvelous bronze, ceramics, paintings and calligraphies offer a visual feast for the eyes, and also provide a good chance for people to learn the profound Chinese history and culture.
If you are into ancient Chinese arts and crafts, then the online Shanghai Museum is definitely worth your time.

Mogao Caves
The Mogao Caves, also known as Thousand Buddha Grottoes, is a UNESCO World Heritage Site located near Dunhuang in northwest China's Gansu Province.
Now visitors can directly browse dozens of classic caves and appreciate the murals(壁画) by cave rooms through the “Digital Dunhuang”, the website of the Mogao Caves. The development of “Digital Dunhuang” not only shocks visitors in a visual sense but also “moves” the Mogan Grottoes outside.

Suppose you were promised $1,440 each day that comes to $525,600 a year. That could never be reduced or changed in your whole life. Sounds great, doesn’t it? Actually, we all do get 1,440 a day—but in minutes, not dollars. 1. It’s possible to get more money, but you can’t make more time.
Many of the management practices that help people make good use of their money can also be applied to your “time currency”. But the question is, are you a good manager of your time? 2.
Find out where your time is going now. Write down everything you do in a day. Include work, study, cooking and meals, cleaning and household maintenance, sleep, family time and mindless activities such as watching TV and getting lost in social media.
3. Ten minutes of planning can save you an hour of time and helps stretch the time you have, and you’ll see pockets of time you can use for things you want to do. “Once people have a clear picture, they actually do have a lot more time than they realize.” Clark, the founder of the Purposeful Planner says.
You can also set limits. Use kitchen timers, phone reminders, apps or other timing devices to stay focused and work more productively, suggests Janine Adams, certified professional organizer of Peace of Mind Organizing.
4. When you have missions to run, instead of making three separate trips on three different days to buy groceries, office supplies or home store products, integrate them—visit all three stores in one trip. It’s more efficient to finish “little one-off” tasks together rather than deal with one at a time throughout the day.
At the end of the day, week, month and year, take a look at how well you’ve managed your time. You’ll see where you could do better and where you’ve completed what you set out to do. Booren compares this progress check to reviewing your annual “financial statement”.
5.Do that over and over and “it forms habit and becomes natural.” Booren says.
A.Try these simple steps to take control of your clock and calendar.
B.Time is one of the most precious and limited resources for people.
C.Grouping small tasks into one job proves to be helpful in daily practice.
D.The most important tasks are not always the same as the most pressing tasks.
E.Focus on what you’re doing and avoid having to repeat the same process twice.
F.Invest a few minutes at the beginning of each day or week to plan and organize.
G.Take time each day to reflect on your achievements and set goals for tomorrow.
The recent world chess championship saw Magnus Carlsen defend his title against Fabiano Caruana. But it was not a contest between the two strongest chess players on the planet, only the strongest humans. Soon after Garry Kasparov, the former world chess champion, lost his re-match against IBM’s Deep Blue in 1997, the short window of human-machine chess competition was shut forever. Unlike humans, machines keep getting faster, and today a smartphone chess app can be stronger than Deep Blue.
In the late 19th century, Alfred Binet hoped that understanding why certain people stood out at chess would unlock secrets of human thought. Sixty years later, Alan Turing wondered whether this sort of ability represents an essential difference between the potentialities of the machine and the mind. Much as airplanes don’t flap their wings like birds, machines don’t generate chess moves like humans do. Early programs that attempted it were weak.
But now things are different. Based on a common game-playing algorithm(算法), AlphaZero incorporates deep learning and other AI techniques to play against itself to generate its own chess knowledge. AlphaZerostarts out knowing only the rules of chess, with no inserted human strategies(策略). In just a few hours, it plays more games against itself than have been recorded in human chess history. It teaches itself the best way to play, reevaluating such fundamental concepts as the relative values of the pieces.It quickly becomes strong enough to defeat the best chess-players in the world, winning 28, drawing 72, and losing none in a victory over Stockfish, one of the strongest chess engines.
The conventional wisdom is that machines would approach perfection with endlessstrategies, usually leading to drawn games. But AlphaZero prefers positions that look risky and aggressive, and it programs itself, which allows it to outclass the world’s top traditional program despite calculating far fewer positions per second. It’s the example of the cliché, “work smarter, not harder.”
AlphaZero shows us that machines can be the experts, not merely expert tools. It’s not going to put chess coaches out of business just yet. But the knowledge it generates is information we can all learn from. AlphaZero is surpassing us in a profound and useful way.
Machine learning systems aren’t perfect, even at a closed system like chess. There will be cases where an AI will fail to detect exceptions to their rules. Therefore, we must work together, to combine our strengths. Instead of being angry against them, it’s better if we’re all on the same side.
