Decision-making under Stress
A new review based on a research shows that acute stress affects the way the brain considers the advantages and disadvantages, causing it to focus on pleasure and ignore the possible negative (负面的) consequences of a decision.
The research suggests that stress may change the way people make choices in predictable ways.
“Stress affects how people learn,” says Professor Mara Mather. “People learn better about positive than negative outcomes under stress.”
For example, two recent studies looked at how people learned to connect images(影像) with either rewards or punishments. In one experiment, some of the participants were first stressed by having to give a speech and do difficult math problems in front of an audience; in the other, some were stressed by having to keep their hands in ice water. In both cases, the stressed participants remembered the rewarded material more accurately and the punished material less accurately than those who hadn’t gone through the stress.
This phenomenon is likely not surprising to anyone who has tried to resist eating cookies or smoking a cigarette while under stress –at those moments, only the pleasure associated with such activities comes to mind. But the findings further suggest that stress may bring about a double effect. Not only are rewarding experiences remembered better, but negative consequences are also easily recalled.
The research also found that stress appears to affect decision-making differently in men and women. While both men and women tend to focus on rewards and less on consequences under stress, their responses to risk turn out to be different.
Men who had been stressed by the cold-water task tended to take more risks in the experiment while women responded in the opposite way. In stressful situations in which risk-taking can pay off big, men may tend to do better, when caution weighs more, however, women will win.
This tendency to slow down and become more cautious when decisions are risky might also help explain why women are less likely to become addicted than men: they may more often avoid making the risky choices that eventually harden into addiction.We can learn from the passage that people under pressure tend to ______.
| A．keep rewards better in their memory |
| B．recall consequences more effortlessly |
| C．make risky decisions more frequently |
| D．learn a subject more effectively |
According to the research, stress affects people most probably in their ______.
| A．ways of making choices | B．preference for pleasure |
| C．tolerance of punishments | D．responses to suggestions |
The research has proved that in a stressful situation, ______.
| A．women find it easier to fall into certain habits |
| B．men have a greater tendency to slow down |
| C．women focus more on outcomes |
| D．men are more likely to take risks |
What will man be like in the future — in 5,000 or even 50,000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today, for man is slowly changing all the time.
Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is relatively a short period of time, so we may suppose that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain’s capacity(容量). As time goes on, however, we shall have to use our brains more and more, and finally we shall need our brains more and more, and finally we shall need larger ones! This is likely to bring a physical change too: the head, in particular the forehead, will grow larger.
Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over long period of time it is likely that man’s eyes will grow stronger.
On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life.
But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald.
Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and motions similar to our own.The passage mainly tells us that __________.
| A．Man’s life will be different in the future |
| B．Future man will look quite different from us |
| C．Man is growing taller and uglier as time passes |
| D．Man’s organs’ functions will change |
What serves as the evidence that man is changing?
| A．Man has got stronger eyes now than he ever had. |
| B．Man’s hair is getting thinner and thinner. |
| C．Man’s arms and legs have become lighter and weaker. |
| D．Man has been growing taller over the past 500 years. |
The change in man’s size of the forehead is probably because __________.
| A．he makes use of only 20% of the brain’s capacity |
| B．his brain has grown larger over the past centuries |
| C．he will use his brain more and more as time goes on |
| D．the other 80% of his brain will grow in due time |
Which of the following is TRUE about a human being in the future?
| A．He is hairless because hair is no longer useful. |
| B．He has smaller eyes and wears better glasses. |
| C．His fingers grow weaker because he doesn’t have to make use of them. |
| D．He thinks and feels in a different way. |
It is implied that __________.
| A．human beings will become less attractive in the future |
| B．body organs will become poorer if they are not used often |
| C．human beings hope for a change in the future life |
| D．future life is always predictable |
When doctors urge overweight kids to pick up more activities，reading probably isn’t what they have in mind. Yet a new study by fatness researchers at Duke University finds that the simple act of reading—depending on the choice of material—can cause weight loss in teenage girls.
The study’s experimental group included 31 fat girls aged 9 to 13，who took part in the Healthy Lifestyles Program at Duke Children’s Hospital. The girls read a novel called Lake Rescue，whose protagonist (主人公) is an overweight teenager who struggles with low selfesteem，feelings of loneliness and teasing because of her size. A group of 33 girls read a different book called Charlotte in Paris，which did not have an overweight character，and another group of 17 girls read neither book.
At the end of the sixmonth experiment，all the girls who read books had lost weight，but the girls who read Lake Rescue lost more. They lowered their body mass index (BMI) by 0.71，compared with 0.33 in the Charlotte group，an average 0.05 increase among the nonreaders.
The idea behind the study，says Dr Sarah Armstrong，director of Healthy Lifestyles，was to find a way to encourage the girls without adopting the restrictive and often authoritative voice of so many other nutrition and diet programs. Lake Rescue was the perfect instrument，says Armstrong；it presents a likable character to whom the girls could relate and whom they could learn from. As the book progresses，its protagonist learns to make healthier lifestyle choices and finds an adviser to help keep her on track. Armstrong says，“She learns that she can become healthier，and the ‘I can do it’ feeling resonates (产生共鸣) with the teenage girls.”What’s the main idea of the passage?
| A．There are different ways to help overweight kids lose weight. |
| B．Lifestyle is important for kids. |
| C．Lake Rescue is the perfect weightlosing instrument. |

| C．different reading materials play different roles in losing weight |
| D．people will become fat if they don’t read |

The expression “keeping up with the Joneses” was first used in 1913 by a young American Arthur Momand. He told this story about himself: he began earning $125 a week at the age of 23. That was a lot of money in those days. Young Momand was very proud of his riches. He got married and moved with his wife to Long Island, outside New York City.
But just moving there was not enough. For when Momand and his wife saw that their neighbors belonged to a country club they too joined a club. And when he saw that rich people were expected to ride horses, Momand went horseback riding every day. Momand and his wife also hired a servant and gave grand parties for their new neighbors.
It was like a race, but one could never finish this race because one was always trying to keep up. Momand and his wife could not do that.
The race ended for them when they could no longer pay for their new way of life. They moved back to an inexpensive New York City apartment.
Momand later said that his experience had been a cruel awakening for him. However, he was able to see the funny side of it. He looked around him and noticed that many people do things just to keep up with their neighbors.
He decided that this would make good stories for many papers across the country. He called it “Keeping up with the Joneses”, because “Jones” is a very common American name. “Keeping up with the Joneses” came to mean keeping up with the people around you. Momand’s stories appeared in different newspapers for over 28 years.
People never seem to tire of keeping up with the Joneses. That is one reason why they read the “right” books, go to the “right” universities and eat in the “right” restaurants. But no matter what one does, Mr. Jones always seems to be ahead.The writer of this passage means to tell us ___________.

Philip was a nine-year-old boy in a Sunday school class of 8-year-old girls and boys. Sometimes the third graders didn’t welcome Philip into their group and usually tricked him. This was not because he was older, but because he was “different”. You see, Philip suffered from a condition called Downs’s Syndrome. This made him “different”, with its facial characteristics, slow responses and mental problems.
One Sunday after Easter, the Sunday school teacher gathered some plastic eggs that pulled apart in the middle. The teacher gave one to each child. On that beautiful spring day, the children were to go out and discover for themselves some symbol of “new life” and place it inside the plastic eggs.
After the children returned to the classroom, the teacher opened their eggs one by one, asking each child to explain that symbol of “new life”. The first opened egg contained a flower. Everyone cheered. In another was a butterfly…. When the teacher opened the last egg, it was empty. “That’s stupid,” said someone. The teacher felt a pull at his shirt. It was Philip. Looking up, Philip said, “It’s mine. I did it. It’s empty. I have new life, because the tomb is empty.” Not a sound was heard in class at all. From that day on, Philip became a real part of the group. They welcomed him, and whatever made him different was never mentioned again.

In the competition of Olympic weightlifting，the athletes try to lift the maximum (最大的) weight they can. There are special conditions they have to meet in order to compete：body weight，height and strength.
The Olympic weightlifting mainly tests the limit of explosive strength (爆发力)．There are not many lifters who really like Olympic weightlifting and the explanation is very simple：they are short of explosive strength.
The weights used for Olympic weightlifting are added in kilograms. The order by which the athletes enter the competition is not general，but it is set depending on the event. Usually the athlete with the lowest weight begins. If he/she is not successful，he/she can try later. There is a maximum of three lifts allowed for every competition.
For many years Olympic weightlifting was only for men. However，now women also take part in Olympic weightlifting. It was at the beginning of the 21st century that women’s competitions entered an organized professional environment. For women，Olympic weightlifting is more difficult because of their different body structure. However，strength training techniques (技术) are widely and successfully used by women，too.
Lots of the athletes who’ve ended up in Olympic weightlifting competitions have started with strength training only to improve their muscle condition and their body power. However，the demarcation line (界线) is not still very clear between power training and Olympic weightlifting. This is how so many lifters have got into Olympic weightlifting competition，even if their purpose was different at the beginning.In the competition of Olympic weightlifting，athletes need to be all of the following EXCEPT________.
| A．the right age | B．the right height |
| C．the right weight | D．the right strength |
