As you're busy with your studies, the weeks during the Spring Festival can be a time when training and healthy eating plans go out of the window. But you can continue running and avoid weight gain during the holiday season. {#blank#}1{#/blank#}

Pick a race

    Having a race on your calendar is a motivation to keep running during the holiday. {#blank#}2{#/blank#} Check our active.com or Running in the city for events near you.

Don't skip breakfast

    If you're going to a holiday party in the evening, don't make the mistake of skipping breakfast. You may think you're saving calories for later. {#blank#}3{#/blank#}

Bring your own healthy dishes

    Chances are that most of the dishes at holiday gatherings are going be high in taste and calories. Bring your own healthy appetizers to the party. The host will appreciate it, and you know where will be at least one wise choice on the buffet table.

    If you are heading to an evening event, eat regular meals and snacks every few hours until party time. You won't arrive at the party ready to attack appetizers. Make sure you include fiber at each meal because it keeps you full longer.

Plan your runs

    It's easy to say that you'll keep running regularly during the holiday season, but sticking to it requires a strategy. Schedule your runs like appointments, so you make them the first thing during a busy week. {#blank#}5{#/blank#}

    Ireland has had a very difficult history. The problems started in the 16th century when English ruler tried to conquer(征服) Ireland. For hundreds of years, the Irish people fought against the English. Finally, in 1921, the British government was forced to give independence to the south of Ireland. The result in that today there are two “Irelands”. Northern Ireland, in the north, is part of the United Kingdom. The Republic of Ireland, in the south is an independent country.

    In the 1840s the main crop, was affected by disease and about 750,000 people died of hunger. This, and a shortage(短缺) of work, forced many people to leave Ireland and live in the USA, the UK, Australia and Canada. As a result of these problems, the population fell from 8.2 million in 1841 to 6.6 million in 1851.

    For many years, the majority of Irish people earned their living as farmers. Today, many people will work on the land but more and more people are moving to the cities to work in factories and offices. Life in the cities is very different from life in the countryside, where things move at a quieter and slower pace.

    The Irish are famous for being warm-hearted and friendly. Oscar Wilde, a famous Irish writer, once said that the Irish were “the greatest talkers since the Creeks”. Since independence, Ireland has revived(复兴) its own culture of music, language, literature and singing. Different areas have different styles of old Irish songs which are sung without instruments. Other kinds of Irish music use many different instruments such as the violin, whistles, etc.

    AlphaGo is a computer program that plays the board game Go.

    In March, 2016, the pride of humankind was crushed (粉碎) by a computer. Google's AlphaGo defeated the South Korean grandmaster (围棋大师) Lee Sedol four games to one, as the world looked on with shock and awe (敬畏). Artificial intelligence (AI, 人工智能) had suddenly reached a new and unexpected height.

    But as smart as AlphaGo is, it's no longer the best Go “player” in the world. Google's artificial intelligence group, DeepMind, has created the next generation of its Go-playing program, called AlphaGo Zero. The new AI program is unique in the way it learned to play Go. Instead of learning from thousands of human matches, as its predecessor (前任) did, AlphaGo Zero mastered Go in just two days without any human knowledge of the game and defeated AlphaGo by day three, reported The Guardian. It then went on to defeat AlphaGo 100 games to zero.

    To learn how to play Go, AlphaGo Zero played millions of matches against itself using only the basic rules of the game to rapidly create its own knowledge of it. Like the previous version, it used “reinforcement (增强) learning to become its own teacher,” according to DeepMind's website.

    “It's more powerful than previous approaches,” David Silver, AlphaGo's lead researcher, told The Guardian, “because by not using human data, or human expertise in any fashion, we've removed the constraints (约束) of human knowledge and it is able to create knowledge itself.”

    AlphaGo Zero's approach to self-learning is a significant advancement in AI that could be applied to help solve some of the world's biggest problems, according to a recent research report published in the journal Nature. For example, DeepMind co-founder Demis Hassabis argues that AlphaGo Zero could probably find cures for a number of serious diseases within weeks, according to The Telegraph. Indeed, the AI is now being used to study protein folding, which is connected to diseases such as Parkinson's and Alzheimer's.

    So now that AI has exceeded (超过) the bounds of human knowledge, perhaps the question is not about what AI can learn from humans, but what humans can learn from AI. We can only wait and see.

    In our twenties, we find it funny when we can't remember our neighbor's cat's name or a handsome actor who starred in a famous movie. In our thirties, we jokingly call it "brain freeze". In our forties, we laugh it off as a" senior moment" and follow up with one of these old age jokes. But the reality is that there comes a point when being forgetful stops being funny and starts to seem a bit dreadful. You think, "Am I losing it？"Or worse, "Is this a sign of Alzheimer's disease（老年痴呆症）？"

    Well, don't worry. The fact that you recognize your own forgetfulness may be a very good sign, at least in terms of the possibility of your developing Alzheimer's disease（AD）. The researchers in a new study show that it's not forgetfulness but not being aware that we're forgetful that we should fear.

    The researchers began with the assumption that one common feature of Alzheimer's dis-ease is a damaged awareness of illness. And they wanted to prove their theory that the lack of awareness can be used to predict whether someone with" mild cognitive（认知的）damage" will progress to full-on AD. For the study, "mild cognitive damage" was defined as someone whose mental state was considered healthy but who had either complained of memory loss or had suffered objective memory loss.

    The researchers used existing data for 1, 062 people between the ages of 55 and 90 that had been recorded over a 12-year period. The data included brain scans, which the researchers used to look for visual signs of reduced glucose uptake（葡萄糖吸收）.It is an objective marker of the sort of reduced brain function that goes along with AD.As expected, glucose uptake was reduced in those with AD. What the researchers also discovered was that glucose uptake was reduced in those with mild cognitive damage who also showed evidence of reduced illness awareness. Finally, the researchers found that those who had reduced illness awareness were more likely to develop AD than those without.

Anyone who has never been to China Braille Library will draw to mind various images of the place.They would wonder how the library works all the way.In fact, the library offers readers a pleasant space with several broad reading rooms on the third floor,and has 18,269 kinds of books, including 3,523 kinds of braille books, 809 kinds of braille journals, 419 kinds of books written in both braille and visible language, and 142 kinds of children's ordinary books.

The library is open to the 17 million visually impaired people in China. This library has an arrangement with China Post, under which it has manufactured a special kind of mailing bag with cards where the address of the library is printed on one side.The borrowers can make phone calls, or send WeChat messages or emails to the librarian, listing the books they are seeking. The librarian then fishes out these books, puts them into the mailing bag, fills in the address of the borrower on the other side of the card and waits for a postman to pick up the bag.Whenever the borrower finishes reading, he or she needs to put the books back into the bag, turn the address card around and put it into a postbox for the books to return to the library.

In the age of multimedia, books have taken various forms. That applies to the world of the visually impaired, too.CBL offers its readers a smart listening device that looks like an old-fashioned cellphone. Guided by a recorded voice, a user has to just press a few buttons to gain access to 20 terabytes of audiobooks stored on the CBL website.The smart listening device is part of a Digital Reading Project for the Blind launched by China Disabled Persons' Federation in 2017.

As part of the program, the government purchased 200,000 such devices and distributed them to the over 400 Braille libraries and barrier-free reading rooms nationwide for lending to the visually impaired. Now, 80 percent of them are still in use, which means more than 160,000 visually impaired people are benefiting from it.
