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 |
Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda(大熊猫) eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.

As computers become more popular in China, Chinese people are increasingly relying on computer keyboards to input Chinese characters. But if they use the computer too much, they may end up forgetting the exact strokes(笔画)of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more.
Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school. And computer dependence is more wide-spread among university students. Almost all their assignments and essays are typed on a computer.
All the students interviewed say they usually use a computer.
It's faster and easier to correct if using a computer. And that's why computers are being applied more and more often to modern education. But when people are taking stock in computers increasingly, problems appear.
“When I'm writing with a pen, I find I often can't remember how to write a character, though I feel I’m familiar with it.”
“I'm not in the mood to write when faced with a pen and paper.”
Many students don't feel this is something to worry about. Now that it's more convenient and efficient to write on a computer, why bother to handwrite?
Many educators think differently. Shi Liwei, the headmaster of a famous primary school in the capital said, “Chinese characters enjoy both practical and aesthetic (审美的) value. But those characters typed with computer keyboards only maintain their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer's emotion. Through one's handwriting, people can get to know one's thinking and personality. Beautiful writing will give people a better first impression of them.”
To encourage students to handwrite more, many primary schools in Beijing have made writing classes compulsory (必修的) and in universities, some professors are asking students to turn in their homework and essays written by hand.Which of the following can best serve as the title of the passage?
A.The Importance of Handwriting and Typing |

A famous teacher was speaking to the students at our school. He began his lesson by holding up a £100 bill. Then he said to the three hundred students, "Who would like to have this £100 bill?" The students began to put up their hands at once.
Then he said, "I am going to give this bill to one of you, but first, let me do this." He then made this bill into a ball. Then he said, "Who wants it?" Hands went into the air.
"Well," he said, "What if I do this?" and he dropped it on the floor and stepped on it. He picked up the dirty, crumpled bill and said, "Who still wants it?" Hands went back into the air.
"My friends," he said, "You've learned a valued lesson today. No matter what I did to the money, you still wanted it because it didn't go down in value. It was still worth £100.
Many times in our lives, we're dropped, crumpled, and stepped on by the chances we take and the things that happen to us. We feel as if we are worth nothing. But remember, no matter what has happened to you, you will never lose your value. You are always valuable to those who love you. Your value doesn't come from what you drop or whom you know,but WHO YOU ARE .

D.The value of money changes when it is made dirty. |
A new argument has been put forward as to whether penguins are disturbed by the presence of tourists in Antarctica.
Previous research by scientists from Keil University in Germany monitored Adelie penguins and noted that the birds’ heart rates increased dramatically at the sight of a human as far as 30 meters away. But new research using an artificial egg, which is equipped to measure heart rates, disputes this. Scientists from the Scott Polar Research Institute at Cambridge say that a slow moving human who does not approach the nest too closely, is not viewed as a threat by penguins.
The earlier findings have been used to partly explain the 20 per cent drop in populations of certain types of penguins near tourist sites. However, tour operators have continued to insist that their activities do not adversely affect wildlife in Antarctica, saying they encourage non-disruptive behavior in tourists, and that the decline in penguin numbers is caused by other factors.
Amanda Nimon of the Scott Polar Research Institute spent three southern hemisphere summers at Cuverville Island in Antarctica studying penguin behavior towards humans. “A nesting penguin will react very differently to a person rapidly and closely approaching the nest,” says Nimon. “First they exhibit large and prolonged heart rate changes and then they often flee the nest leaving it open for predators (掠夺者) to fly in and remove eggs or chicks.” The artificial egg, specially for the project, monitored both the parent who had been ‘disturbed’ when the egg was placed in the nest and the other parent as they both took it in turns to guard the nest.
However, Boris Culik, who monitored the Adelie penguins, believes that Nimon’s findings do not invalidate his own research. He points out that species behave differently ---- and Nimon’s work was with Gentoo penguins. Nimon and her colleagues believe that Culik’s research was methodologically flawed because the monitoring of penguins’ responses needed capturing and restraining the birds and fitting them with beart-rate transmitters. Therefore, argues Nimon, it would not be surprising if they became stressed on seeing a human subsequently. According to the passage, what overall message is presented?
A.No firm conclusions are drawn. |
B.Neither Culik’s nor Nimon’s findings are of much value. |
C.Penguin reduction is closed related to tourist behavior. |
D.Tourists are not responsible for the fall in penguin numbers. |
Which ONE argument of the following is stated in the passage?
A.Penguins are harder to research when they have young. |
B.Tour operators should encourage tourists to avoid Antarctica. |
C.Not all penguins behave in the same way. |
D.Penguins need better protection from tourists. |
What do you notice about the views presented in the passage?
A.They are groundless. | B.They are factual. |
C.They are descriptive. | D.They are conflicting. |
What does the underlined word (final line) probably mean?
A.Later on. | B.Calmly. | C.Separately. | D.In the same place. |
