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.
1.The subject discussed in this text is _________.

It is important to protect yourself from harmful rays. But if you think a high-factor sunscreen keeps you safe from harmful rays, you may be wrong. Research in this week’s Nature shows that while factor 50 reduces the number of melanomas（黑瘤）and delays their occurrence, it can’t prevent them. Melanomas are the most aggressive skin cancers. You have a higher risk if you have red or blond hair, fair skin, blue or green eyes, or sunburn easily, or if a close relative has had one. Melanomas are more common if you have periodic intense exposure to the sun. Other skin cancers are increasingly likely with long-term exposure.
There is continuing debate as to how effective sunscreen is in reducing melanomas – the evidence is weaker than it is for preventing other types of skin cancer. A 2011 Australian study of 1,621 people found that people randomly selected to apply sunscreen daily had half the rate of melanomas of people who used cream as needed. A second study, comparing 1,167 people with melanomas to 1.101 who didn’t have the cancer, found that using sunscreen routinely, alongside other protection such as hats, long sleeves or staying in the shade, did give some protection. This study said other forms of sun protection – no sunscreen – seemed most beneficial. The study relied on people remembering what they had done over each decade of their lives, so it’s not entirely reliable. But it seems reasonable to think sunscreen gives people a false sense of security in the sun.
Many people also don’t use sunscreen properly applying insufficient amounts, failing to reapply after a couple of hours and staying in the sun too long. It is sunburn that is most worrying – recent research shows five episodes of sunburn in the teenage years increases the risk of all skin cancers.
The good news is that a combination of sunscreen and covering up can reduce melanoma rates, as shown by Australian figures from their slip-slop-slap campaign. So if there is a heat wave this summer, it would be best for us, too, to slip on a shirt, use sunscreen and slap on a hat.
1.What’s people’s common expectation of high-factor sunscreen?
A. It will protect them from sunburn.
B. It will keep their skin smooth ad fair.
C. It will work for people of any skin color.
D. It will delay the occurrence of skin cancer.
2.What can we learn from the second paragraph?
A. Sunscreen can prevent all kinds of skin cancers.
B. The studies are based on direct observation of the subjects.
C. The studies may help people select the most effective sunscreen.
D. Daily application of sunscreen helps reduce the incidence of melanomas.
3.What does the author suggest in order to reduce melanoma rates?
A. Staying in the shade whenever possible.
B. Using covering up instead of sunscreen.
C. Using both covering up and sunscreen.
D. Applying the right amount of sunscreen.
4.What is the best title for the text?
A. No Way to Stop Harmful Rays!
B. Does Sunscreen Prevent Skin Cancer?
C. Did You Use Sunscreen In the Right Way?
D. Skin Cancer-The Biggest Threat to Human Beings!

It is said that if you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise — and as a result, we are growing old unnecessarily soon.
Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the process of aging could be slowed down. With a team of colleagues at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages and varying occupations. Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side parts of the brain, which controls functions like eating and breathing, does not contract with age, and one can continue living without intellectual on economical faculties. Contraction of front and side parts — as cells die off — was observed in some subjects in their thirties, but it was still not evident in some sixty-and seventy-year-olds. Matsuzawa concluded from his tests that there is a simple way to the contraction normally connected with age — using the head.
The findings show in general terms that contraction of the brain begins sooner in people in the country than in the town. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking (萎缩) brains as the farm worker, bus driver and shop assistant.
Matsuzawa's findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. “The best way to maintain, good blood circulation is through using the brain.” he says. “Think hard and engage in conversation. Don’t rely on pocket calculators.”
1.The team of doctors wanted to find out ______.
A. the size of certain people's brains
B. how to make people live longer
C. which people are most intelligent
D. why certain people are aging sooner than others.
2.On what are their research findings based?
A. The study of brain volumes of different people.
B. The study of brain volumes of old people.
C. The latest development of computer technology.
D. A survey of farmers in northern old people.
3.The doctors’ tests show that _______.
A. our brains shrink as we grow older
B. the front section of the brain does not shrink
C. sixty-year-olds have better brains than thirty-year-olds
D. some people's brains have contracted more than other people's
4.According to the passage, which people seem to age more slowly than the others?
A. Lawyers. B. Farmers.
C. Clerks. D. Shop assistants.
