Decision-thinking is not unlike poker—it often matters not only what you think, but also what others think you think 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, 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), 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.The subject discussed in this text is _________.

When Armida Armato’s daughter, Alexia, came home from school one day last year keen to go on a school trip to Ecuador, she wasn’t too sure how to feel. She was happy that her daughter could experience something she never did as a teen but was fearful of letting her travel to such a remote part of the world.
Alexia was 16 at the time, a student at Westwood High School. The school sponsored a humanitarian trip for 26 students and two teachers to spend 18 days living in a mountain village to build a one-room school. Even though Armato trusted her daughter, the other students and the teachers, she was worried about the side effects from the travel vaccines, possible accidents, and medical care.
Now that Alexia was home, Armato said she saw her daughter’s new maturity, greater confidence and independence. “This is the best thing I ever did,” Alexia said. “The experience was so eye-opening and life-changing. You’re with people who are not as lucky as you are. They live in very poor conditions but they’re so happy and outgoing. You say, ‘My God. I’m taking everything for granted back home.’”
She said they built a one-room school from scratch with no mechanical cement mixers. They used their hands, shovels and basic tools. She and another student lived with a local family in a small village about eight hours outside the capital, Quito. Despite the initial strangeness and knowing only basic Spanish, she said they grew very close and felt like a family.
Every year, groups of students at Montreal High School like Alexia pack their bags and fly off with classmates and teachers to developing countries where they volunteer for a variety of projects.
“Armato’s worries are very common among parents,” says Bill Nevin, a teacher at St. George’s High School. He organizes a humanitarian rip to India to the Sheela Bal Bhavan orphanage and says the three biggest fears families have are health, security and contact.When hearing the news that her daughter would go on a school trip to Ecuador, Armato was _______.
| A.proud and happy | B.supportive but concerned |
| C.fearful and nervous | D.excited but puzzled |
The underlined phrase “from scratch” in Paragraph 4 probably means “______”.

| C.ending up in failure | D.starting from the beginning |
What would be the best title for the text?
| A.Volunteering helps students grow and develop. |
| B.School trips make parents worried about their children. |
| C.Ecuador is the most attractive travel destination in the world. |
| D.Brave Alexia dreams to work in Ecuador one day. |
There are many commonly held beliefs about eye glasses and eyesight that are not proven facts. For instance, some people believe that wearing glasses too soon weakens the eyes. But there is no evidence to show that the structure of eyes is changed by wearing glasses at a young age. Wearing the wrong glasses, however, can prove harmful. Studies show that for adults there is no danger, but children can develop loss of vision if they have glasses inappropriate for their eyes.
We have all heard some of the common myths about how eyesight gets bad. Most people believe that reading in dim light causes poor eyesight, but that is untrue. Too little light makes the eyes work harder, so they do get tired and strained. Eyestrain also results from reading a lot, reading in bed, and watching too much television. However, although eyestrain may cause some pain or headaches, it does not permanently damage eyesight.
Another myth about eyes is that they can be replaced, or transferred from one person to another. They are close to one million nerve fibers(纤维) that connect the eyeball to the brain, so it is impossible to attach them all in a new person. Only certain parts of the eye can be replaced. But if we keep clearing up the myths and learning more about the eyes, some day a full transplant may be possible.If a child wears appropriate glasses, __________________________.
| A.he will lose sight |
| B.the structure of his eyes will be changed |
| C.it is harmful |
| D.the structure of his eyes will keep the same as before |
If an adult wears inappropriate glasses, __________________.
A. it will make no difference to his eyes
B he will suffer a lot from the loss of vision
C. his eyes will be weakened
D. the structure of his eyes will be changedWith the technology we now have, doctors _______________.
| A.still can’t do eye transplant even certain parts of the eye |
| B.can transplant the whole eye in a new person |
| C.can transfer certain parts of the eye in a new person |
| D.know almost nothing about eyes |
The author of the passage tends to _________________.
| A.explain wearing glasses is no harm to children |
| B.correct people’s wrong beliefs about eyes |
| C.explain the importance of protecting our eyes |
| D.imagine what doctors can do with the eye in the future |
Needa solid excuse to dust off your running shoes? Joggers have been found to live an average of six years longer than those who don't jog.
However, you’ll have to run for at least one hour a week for benefit, according to a new study in Denmark.
Researchers found that jogging was associated with a 44 per cent reduction in the relative risk of death for those over 35 years compared with deaths among those who did not run.
The same benefit applied to both men and women.
The 44 per cent reduction translates to an ‘age-adjusted survival benefit’ of 6.2 years in men and 5.6 years in women, according to Dr. Peter Schnohr, chief cardiologist from the Copenhagen City Heart study.
Furthermore, the jogger’s lives are not only longer but happier too as those who ran reported an overall sense of well-being, said Schnohr.
The results of our research allow us to definitively answer the question of whether jogging is good for your health,' Schnohr said in a statement.
'We can say with certainty that regular jogging increases longevity. The good news is that you don't actually need to do that much to reap the benefits,' he continued.
The study also found that the optimum benefit of jogging was for those who jogged at a slow-to-average pace for between an hour and two and a half hours spread over two or three weekly sessions.
Researchers then compared deaths among the joggers among the non-joggers in the main study pool of almost 20,000.
Over 35 years, 122 joggers died compared with 10,158 non-joggers.
All the participants involved with the Copenhagen City Heart Studyhad their cholesterol, blood pressure, blood glucose, and BMI, measured and they were questioned about smoking, alcohol consumption, education, and income.In order to do good to health, the joggers should run ______.
| A.for at least one hour daily |
| B.for at least one hour weekly |
| C.for at least one hour monthly |
| D.for at least one hour yearly |
Why do joggers live more happily?
| A.Because they taste part sense of happiness. |
| B.Because they taste overall sense of hardship. |
| C.Because they taste whole sense of happiness. |
| D.Because they taste part sense of success. |
Which of the following is true according to the article?
| A.Regular jogging decreases longevity. |
| B.The more jogging you do the longer you live. |
| C.The less jogging you do the longer you live. |
| D.Regular jogging makes people live longer. |
It can be inferred that the study of jogging benefit is ______.
| A.complete and reliable |
| B.partial and unbelievable |
| C.incomplete but reasonable |
| D.reasonable but undependable |
BBC Sports program Sunday.
We are currently planning our Volunteer Program, which will ensure volunteers are trained and ready to go for 2012.Up to 70,000 volunteers will be needed to help put on the London 2012 Olympic and Paralympic Games. Our program will aim to encourage a wide range of people to join in. We will provide the training to make sure our volunteers' skills are of the highest standard. London 2012 is an opportunity to inspire everyone to develop their interests and volunteer—in sport and also more widely within their community.
Applications will open in the late 2011.We'll recruit(招募) volunteers from across the UK—from a range of communities and backgrounds. Our recruitment process will be open and fair. Our goal is to select applicants who meet our standards and who will bring passion, enthusiasm and energy to the Games. Previous volunteering experience is not necessary. We'll give each successful applicant a specific role, allowing them to contribute meaningfully to the Games. There will be two kinds of Games volunteer—specialist and generalist.
Specialist volunteers will have specific existing skills or qualifications that are needed for them to complete the role, for example, sport or medical training.
Generalist volunteers will not need any special skills or qualifications and will receive full training. They might be given roles in areas such as event services, uniform distribution (分发) and village operations. All volunteers will be expected to attend training events that will give them the knowledge they need to carry out their role.
