Today, roller skating is easy and fun．But a long time ago, it wasn’t easy at all. Before 1750, the idea of skating didn’t exist. That changed because of a man named Joseph Merlin. Merlin’s work was making musical instruments. In his spare time he liked to play the violin. Joseph Merlin was a man of ideas and dreams. People called him a dreamer.
One day Merlin received an invitation to attend a fancy dress ball. He was very pleased and a little excited. As the day of the party came near, Merlin began to think how to make a grand entrance at the party. He had an idea. He thought he would get a lot of attention if he could skate into the room.
　　Merlin tried different ways to make himself roll. Finally, he decided to put two wheels under each shoe. These were the first roller skates. Merlin was very proud of his invention and dreamed of arriving at the party on wheels while playing the violin.
　　On the night of the party Merlin rolled into the room playing his violin. Everyone was astonished to see him. There was just one problem. Merlin had no way to stop his roller skates. He rolled on and on. Suddenly, he ran into a huge mirror that was hanging on the wall. Down fell the mirror, breaking to pieces. Nobody forgot Merlin’s grand entrance for a long time!

Tuesday the twelfth was my birthday. I  16 a day of cake and presents  17__     it turned into a day of mystery(神秘). Someone sent a bottle with a letter and a treasure map   18 .

“The map says you have to turn when you see a large stone with a red circle,” said one of them.
“What do we do after the turn?” I asked   26 .

With only a click of the mouse, rumors can be forwarded between microblogs very quickly. As an example, recently, perceptive netizens discovered that some photos displayed on microblogs depicting Beijing’s June rainstorm had actually been fabricated.

Sina.com is one of the major internet portals(门户网站) in China with hundreds and thousands of users, and a majority of celebrities and renowned citizens have their microblog accounts on this portal. As recently as six months ago, the website decided to establish a specialized team to verify rumors and provide accurate information for its users. Tan Chao is in charge of the team.

“Before I took the job, I usually couldn’t identify what information was real and what was fake. But during the rumor verification process, we discovered that a lot of information was false, including fake photos, fake news stories and rumors that had been spread through microblogs.”

It‘s not just website portals which are taking on fact-checking responsibilities, but also a number of civic-minded netizens, who recently set up a Rumor Verification Federation on Sina.com’s microblog system to help netizens identify fake information online.

　　Dianzizheng is the team leader of the federation. He says they’ve publicized more than 150 pieces which refute rumors, which attracted more than 10 thousand visitors within two months.

　　“We live in an age of new media, so we can’t use the old methods to verify rumors. We can’t wait for the media to verify the facts with related administrative departments and then release a formal announcement. We can’t allow rumors to run rampant and then deal with it, we need to fight rumors while they’re spreading. I think that this is the best way to deal with rumors nowadays.”

　　Some experts say this demonstrates the advantages of the internet compared to other traditional media. The open platform allows information to be examined and clarified by netizens. But experts like Ding Wenguo, President of the Journalism and Communication College at the China University of Political Science and Law says this self-correction function of the internet is still quite limited.

　　“It’s still quite difficult to tell which information is true in such an open environment by just reading a number of different opinions on the same issue. This is something which we need to pay attention to. If society is deluged with too much false information, and it’s allowed to spread in such a fast manner, then people will be suspicious of all kinds of information including important information from authorities. It also exacerbates(恶化) problems relating to social communications and mutual-understanding, which in turn harms society as a whole.”

　　Experts suggest that the government should react more quickly in the internet age. Once a rumor begins to spread, administrative departments should make announcements as early as possible to dispel rumors before they lead to bad outcomes.

You maybe surprised to learn that one of the best steps you can take to protect your health is to step outside and spend some time in the grass, dirt and water．
Our ancestors enjoyed the healing power of nature，and now scientists are starting to catch up．According to research in recent years，just having a view of nature has been shown to improve hospital patients' recovery and reduce illness rates among office workers．Also，exposure(曝露) to wildlife，horseback riding，hiking，camping and farms can be helpful for a variety of health conditions in adults and children．
Much of this type of research is focusing on children，and in fact an entire movement has quickly developed to connect kids with the healing power of nature．
Obesity（肥胖）．Rates of childhood obesity have grown sharply in recent years，and this is partly because of reduced outdoor activity time．Increasing the time students spend learning about nature，both in and outside the classroom，would help solve this problem．Such lessons are often more attractive for students and often lead them to become more active outside．
Attention deficit hyperactivity disorder（ADHD）（注意力缺失症）．Exposure to ordinary natural settings in the course of common after­school and weekend activities may be effective in reducing attention deficit symptoms in children．Participation in green activities—such as nature walks—helped ADHD patients from a wide range of backgrounds to stay focused and complete tasks．
Stress．Access to nature，even houseplants，can help children cope with stress．
Depression and seasonal emotional disorder．Major depression requires medical treatment，but physical activity，especially outdoors，can help ease symptoms．For your average case of winter blues，experts suggest spending time outside every day and，if possible，taking the family to a sunny vacation spot in mid­winter．
Experts emphasize that you needn't go to wilderness preserves to enjoy nature's benefits—simply walking in a city park or growing in a rooftop garden can make a difference．

　　Decision-thinking is not unlike. It often matters not only what you think, but also what others think you think and what you think they think you think. The mental process（过程） is similar. Naturally, this card game has often been of considerable interest to people who are, by any standards, good thinkers.
　　The great mathematician John von Neumann was one of the founders of game theory. In particular, he showed that all games fall into two classes; there are what he called games of 'perfect information', games like chess where the players can't hide anything or play tricks; they don't win by chance, but by means of logic and skills. Then there are games of 'imperfect information', like poker, in which it is impossible to know in advance that one course of action is better than another.
　　One mistaken idea about business is that it can be treated as a game of perfect information. Quite the reverse, business and life itself are games which we must normally play with very imperfect information. Business decisions are often made with many unknown and unknowable factors（因素）, as best poker players. But few business people find it comfortable to admit that they are taking a chance, and many still prefer to believe that they are playing chess, not poker.

　　A．the process of reaching decisions
