Trying to make a big decision while you’re also preparing for a scary presentation? You might want to hold off on that. Feeling stressed changes how people weigh risk and reward. However, an article published in Current Directions in Psychological Science, a journal of the Association for Psychological Science, suggests stressed people pay more attention to the positive sides of a possible outcome.
It’s a bit surprising that stress makes people focus on the way things could go right, says Mara Mather of the University of Southern California. She co-wrote the review paper with Nichole R.Lighthall. “This is sort of not what people would think, ” Mather says. “Stress is usually associated with negative experiences, so you’d think, maybe I’m going to be more focused on the negative outcomes.”
But researchers have found that when people are under stress, they start paying more attention to positive information and discounting negative information. “Stress seems to help people learn from positive feedback and impairs(削弱)their learning from negative feedback, ” Mather says.
When people under stress are making a difficult decision, they may pay more attention to the good sides of the alternatives they’re considering and less to the problems. So someone who’s deciding whether to take a new job and is feeling stressed by the decision might focus on the increase in salary more than the longer commute(上下班往返).
The increased focus on the positives also helps explain why stress plays a role in addictions. People under stress have a harder time controlling their urges. “The compulsion to get that reward comes stronger and they’re less able to resist it,” Mather says. A person who’s under stress might think only about the good feelings they’ll get from a drug, while the downsides shrink into the distance.
Stress also increases the differences in how men and women think about risk. When men are under stress, they become even more willing to take risks; when women are stressed, they get more conservative(保守的). Previous research backs this up — men usually react to difficulties while trying to fight them or escape them; women try to find friends and improve their relationships.By saying “You might want to hold off on that” in the first paragraph, the writer suggests that .
A.you might want to delay making your big decision |
B.you should save the presentation for later |
C.you should avoid taking risks |
D.you might benefit from the stress |
From the article, we can conclude that stress .
A.often leads people to take more risks |
B.often leads people to make balanced decisions |
C.makes people think more of negative results |
D.makes people ignore the negative side of problems |
Which of the following is TRUE according to the article?
A.Stress is helpful in getting rid of addictions. |
B.People who are addicted to drugs are easily stressed. |
C.When women are stressed, they do not tend to take risks. |
D.When men are stressed, they are more likely to develop an addiction. |
What is the central theme of the article?
A.Stress can affect decision-making. |
B.Stress increases our desire to get rewards. |
C.We should think more about the upside of problems. |
D.There is a link between stress and negative experiences. |
Much of the water we use comes from snow. Melting snow provides water for rivers, electric power centers and agricultural crops. In the western United States, mountain snow provides up to 75% of all surface water supplies.
Snowfall helps to protect plants and some wild animals from cold, winter weather. Fresh snow is made largely of air trapped among the snow crystals. Because the air has trouble moving, the movement of heat is greatly reduced.
Snow also is known to influence the movement of sound waves. When there is fresh snow on the ground, the surface of the snow takes in, or absorbs, sound waves. However, snow can become hard and flat as it becomes older or if there have been strong winds. Then the snow's surface will help to send back sound waves. Under these conditions, sounds may seem clearer and travel farther.
Generally, the color of snow and ice appears white. This is because the light we see from the sun is white. Most natural materials take in some sunlight. This gives them their color. However, when light travels from air to snow, some light is sent back, or reflected. Snow crystals have many surfaces to reflect sunlight. Yet the snow does take in a little sunlight. It is this light that gives snow its white appearance.
Sometimes, snow or ice may appear to be blue. The blue light is the product of a long travel path through the snow or ice. In simple terms, think of snow or ice as a filter. A filter is designed to reject some substances, while permitting others to pass through. In the case of snow, all the light makes it through if the snow is only a centimeter thick. If it is a meter or more thick, however, blue light often can be seen.How many functions of snow are discussed in the passage?
A.One | B.Two | C.Three | D.Four |
Why does snowfall help to protect plants from cold?
A.Because snow crystals contain heat. |
B.Because snow crystals have air in them. |
C.Because snow crystals are easy to blow away. |

It can be inferred that ______.
A.hard snow is better in protecting wild animals than fresh snow |
B.fresh snow is better in sending sound waves than hard snow |
C.fresh snow is better in taking in sound waves than hard snow |
D.hard snow provides less water than fresh snow |
The color of snow and ice appears white because snow crystals________.
A.send back none of the sunlight | B.send back all of the sunlight |
C.take in most of the sunlight | D.take in some of the sunlight |
Astronauts on shorter shuttle missions often work very long days. Tasks are scheduled so tightly that break times are often used to finish the day's work. This type of schedule is far too demanding for long missions on the International Space Station (ISS). ISS crewmembers usually live in space for at least a quarter of a year. They work five days on and two days off to mimic the normal way they do things on Earth as much as possible. Weekends give the crew valuable time to rest and do a few hours of housework. They can communicate with family and friends by email, internet phone and through private video conferences.
While astronauts cannot go to a baseball game or a movie in orbit, there are many familiar activities that they can still enjoy. Before a mission, the family and friends of each ISS crewmember put together a collection of family photos, messages, videos and reading material for the astronauts to look at when they will be floating 370 kilometers above the Earth. During their mission, the crew also receives care packages with CDs, books, magazines, photos and letters. And as from early 2010, the internet became available on the ISS, giving astronauts the chance to do some "web surfing" in their personal time. Besides relaxing with these more common entertainments, astronauts can simply enjoy the experience of living in space.
Many astronauts say that one of the most relaxing things to do in space is to look out the window and stare at the universe and the Earth. Both the shuttle and the ISS circle the planet several times each day, and every moment offers a new view of the Earth's vast land mass and oceans.What does the word "mimic" in Paragraph 1 probably mean?
A.copy | B.find | C.change | D.lose |
Which of the following best describes the families of the astronauts on the ISS?
A.They are impatient and annoyed. | B.They are worried and upset. |
C.They are caring and thoughtful. | D.They are excited and curious. |
In the final paragraph, the author shows that astronauts ________.
A.love to see the Earth from space | B.find living in space a bit boring and tiring |
C.regard space life as common | D.get more pleasure in space than on the Earth |
The passage mainly discusses how astronauts ________.
A.work for longer missions in space | B.spend their free time in space |
C.observe the Earth from space | D.connect with people on the Earth |
If you do not use your arms or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way.
When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong.
If a friend says that his arms and legs are weak, we know that it is his fault. But if he tells us that he has a poor memory, many of us think that his parents are to blame, and few of us know that it is just his own fault.
Have you ever found that some people can't read or write but they have better memories? This is because they cannot read or write and they have to remember things; they cannot write them down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised.
So if you want to have a good memory, learn from the people: practise remembering.If you do not use your arms or legs for some time, ______.
A.you can't use them any more |

It was a winter morning, just a couple of weeks before Christmas 2005. While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival, he parked his bike outside the back door as he usually does. After putting in 10 hours of labor, he returned to find his bike gone.
The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour weeks to support his young family. And the bike was also used to get groceries(食品杂货), saving us from having to walk along long distances from where we live.
I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before.
People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had a spreading effect in our lives because it strengthened our faith in humanity(人性) as a whole. And it has influenced us to be more mindful of ways we, too, can share with others. No matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting.Why was the bike so important to the couple?
A.They used it for work and daily life. |
B.It was their only possession(财产). |
C.It was a nice Kona 18 speed. |
D.The man‘s job was bike racing. |
We can infer from the passage that __________.
A.the couple worked 60 hours a week |
B.people were busy before Christmas |
C.the stranger brought over the bike |
D.life was hard for the young family |
How did people get to know the couple’s problem?
A.From a stranger. |
B.From a newspaper. |
C.From TV news |
D.From radio broadcasts. |
What do the couple learn from their experience?
A.Strangers are usually of little help. |
B.One should take care of their bike. |

The evidence for harmony(和谐) may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly-held image (形象)of unhappy teenagers locked in their room after endless family quarrels.
An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it had ever been in the past.“We were surprised by just how positive(肯定的) today’s young people seem to be about their families,” said one number of the research team.“They’re expected to be rebellious(叛逆的) and selfish but actually they have other things on their minds:they want a car and material goods,and they worry about whether school is serving them well. There’s more negotiation(商议) and discussion between parents and children,and children expect to take part in the family decision-making process. They don’t want to rock the boat(捣乱).”
So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends. “My parents are happy to discuss things with me and willing to listen to me,” says 17-year-old Daniel Lazall. “I always tell them when I‘m going out clubbing. As long as they know what I’m doing, they’re fine with me.” Susan Crome, who is now 21, agrees. “Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I’d done all my homework, could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”
Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage rebellion is not rooted in real facts. A researcher comments(评论),“Our surprise that teenagers say they get along well with their parents comes because of a brief period in our social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over. ”What is the popular images of the teenager today?
