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.

The US government has started a website, Admongo, to help children think critically about the advertising aimed at them. It claims to provide visitors with an “aducation” through games and other entertainment.
A cartoon man dressed in old time pilot clothing greets visitors to Admongo. "Call me Haiz", he says upon arrival in a rocket ship that opens up with a crazy world inside it. Spacey dance music plays in the background as Haiz tells visitors that they need to learn about advertising.
Its inventors say eight to twelve years old is the age kids develop their critical thinking abilities. Kids that age are also a big market for advertisers.
The idea behind Admongo is to teach children three things: To identify the advertiser. To know what the advertiser is really saying. And to know what the advertisement is trying to get the child to do.
Children learn these things through a video game. They create their own game character. They can choose different skin colors, hair styles, eye and mouth shapes. Then they begin a trip through ad-land, where there are ads on buses and billboards. The players have to find all the marketing in the neighborhood before they can move on to the next level.
The Admongo game takes players inside a home, to the advertising studio and everywhere else ads can be found. It is a complete exploration of the world of marketing.
One such area is food marketing. The Federal Trade Commission (FTC) says it is a big business. The FTC estimates that food, drink and fast-food restaurants spent more than one and a half billion dollars on advertising to young people in 2009.
The FTC says children are important for three reasons. They buy products. They influence parents and caregivers to buy. And they are the future adult buyers of the products.
A recent study says most advertising aimed at children is for foods of the lowest nutritional value. First Lady Michelle Obama has said she would like to see advertisers marketing healthy foods for children.

Most children now chat daily either online or through their mobile phones. They are connecting to a huge number of other children all over the world. Some are shy “in real life” but are confident to communicate with others online; others find support from people of their own age on relationship issues, or problems at home.
Sometimes the online world, just like the real world, can introduce problems, such as arguments. Going online is great fun, but there are also a few people who use the Internet for offensive (冒犯性的) or illegal aims. Children must be made aware of both the good things and the dangers.
To keep children safe your management must cover the family computer. Just as you decide which TV pro-grams are suitable, you need to do the same for the websites and chat rooms your children visit. Remind your children that online friends are still strangers. Re-minding them of the risks will keep them alert (警惕).
Computer studies are part of schoolwork now, so it’s likely that your children may know more than you do. We get left behind when it comes to the latest gad-gets and the interactive areas of websites, like chat rooms and message boards, which are especially strange. The language of chat is strange to many parents, too. Chatters love to use abbreviations (缩写) such as: atb — all the best, bbfn — bye bye for now, cul8er — see you later, gr8 — great, Idk — I don’t know, imbl — it must be love, kit — keep in touch, paw — parents are watching, lol — laugh out loud, xlnt — excellent!

FRIDAY, Aug. 3 (Health Day News) -- Middle school students who are physically fit are likely to score higher on standardized tests measuring reading and math abilities, a new study has found. And, the average scores went up in connection with levels of fitness, the findings showed.
“The more physically fit kids were, the higher their scores,” said the study’s lead author, Trent Petrie, director of the Center for Sport Psychology at the University of North Texas in Denton. “Parents should encourage their kids to be physically active. There are some real cognitive (认知的) and academic benefits that come from physical fitness”, Petrie said.
Results of the study are scheduled to be presented Friday at the annual meeting of the American Psychological Association in Orlando, Fla. The study included more than 1,200 middle school students from five schools in a suburban area of Texas, with 561 boys and 650 girls. About 57 percent of the children were white, and nearly one-quarter were Mexican American. Nine percent were black and about 2 percent were of Asian descent.
The school district provided the researchers with information on the children’s race, age, grade level and whether they qualified for the free school lunch program, which was an indicator of the family’s socioeconomic status. The schools also provided scores to the tests, which were given between one and four months after the researchers had assessed the children’s levels of fitness. Fitness tests were administered during physical education classes to determine the youngsters’ heart and lung health (cardiorespiratory fitness), as well as their body mass index (BMI), an indicator of how much body fat a person has. The children also filled out questionnaires that helped the researchers determine factors such as self-esteem and social support.
After accounting for factors such as age, sex, family income and self-esteem, the researchers found that for both boys and girls, higher levels of heart and lung health predicted better scores on both the math and reading tests.
For boys, perceived (感观的) social support also seemed to increase their reading scores, the investigators found. In girls, while being physically fit predicted higher reading scores, so too did a higher BMI-- which indicates more body fat. “We were a little surprised by this finding,” Petrie said.
“It was not as strong an association as the one with physical fitness,” he added. The authors suspect it may have something to do with girls this age entering adolescence, which may be related to a higher BMI and slightly higher brain development. He said he plans to make great effort to look for this relationship again in larger studies to see if it was a chance finding, or if the association holds up.
“While we can’t say 100 percent that physical fitness causes better academic performance, we can say that there is a strong and predictive relationship between physical fitness and academic performance,” Petrie said.
“It’s hard to tease apart (梳理) the exact reason for this association,” said Becky Hashim, an attending clinical psychologist and assistant professor in the departments of psychiatry and pediatrics at the Children’s Hospital of Montefiore, in New York City.
“It may be that the children are getting more oxygen. When the heart and lungs are working at a higher capacity, it may allow the brain to work at peak performance. Children who are less fit may be sleepier during school,” she noted. “I personally feel that there’s probably a strong relationship between the confidence you get from being able to do something physical well and academic performance.”
Whatever the reason behind this association may be, “there’s certainly no harm in pushing physical fitness,” Hashim added. “Physical fitness may make you feel better, give you more confidence and improve your performance across the board,” she said.
Petrie agreed. “Physically fit kids are happier, have higher self-esteem and, tend to have better relationships, and now we’re beginning to see that there also seem to be benefits cognitively and academically. Our study sends a strong warning to policymakers to reconsider the service program of physical education classes for kids,” he said.
【小题1】How did the school district help the researchers carry out the study?

Looking for a new weight loss plan? Try living on top of a mountain. Mountain air contains less oxygen than air at lower altitudes, so breathing it causes the heart to beat faster and the body to burn more energy. A handful of studies have found that athletes training at high altitudes tend to lose weight. Doctor Florian Lippl of the University Hospital Of Ludwig-Maximilians-university Munich wondered how the mountain air would affect overweight individuals if they weren’t doing any more physical activity than usual.
Lippl and his colleagues invited 20 overweight men to an environmental research station about 300 meters below the summit of Zugspitze, a mountain around 2,970 meters near the Austrian border. They were allowed to eat as much as they liked. The men also gave blood so that researchers could test for hormones linked to appetite and fatness. At the end of the week, the men, whose mean weight starting out was 105kg, had lost on average about l.5kg. The men’s blood pressure also dropped, which the researchers believed was due to weight lost.
Exactly what caused the weight loss is uncertain. Loss of appetite is common at higher altitudes, and indeed the men ate significantly less than usual—about 700 calories fewer per day. Lippl also notes that because their consumption was being recorded, they may have been more self-conscious about what they ate. Regardless, eating less accounts for just l kg of the l.5 kg lost, says Lippl. He thinks the increased metabolic (新陈代谢的) rate, which was measured, also contributed to weight loss but cannot separate the different effects with the given data.
Appetite loss at high altitudes could certainly be key, notes Damian Bailey, a physiologist at the University of Glamorgan, UK, who recently lost 11 kg during a 3-month expedition to the Andes in Chile.   
Unfortunately, for the average person there is no treatment that can resemble living at high altitude, says Lippl. The only alternative is hypobaric chamber, which exposes subjects to low oxygen and isn’t practical as a treatment. He says, half- jokingly, “If fat people plan their holidays, they might not go to the sea, but maybe to the mountain.”

The best way of learning a language is using it. The best way of learning English is talking in English as much as possible. Sometimes you’ll get your words mixed up(混合)and people will not understand you. Sometimes people will say things too quickly and you can’t understand them. But if you keep your sense of humor(幽默感),you can always have a good laugh at the mistakes you make. Don’t be unhappy if people seem to be laughing at your mistakes. It’s better for people to laugh at your mistakes than to be angry with you, because they don’t understand what you are saying. The most important thing for learning Englsih is：“Don’t be afraid of making mistakes because everyone makes mistakes.”
【小题1】The writer thinks that the best way for you to learn a language is_______.

A. Be brave in your requests
B. You get what you tolerate
C. Don’t feel guilty of your requests
D. Don’t think others are mind readers
E. Don’t make a “no” mean more than it does
F. Be specific about what you want and when you want it
Be Bold: Ask for What You Really Want!
Have you ever been in a situation that is causing you to feel annoyed, frustrated, or unappreciated? We all experience them, but often we don’t have the courage to change them or ask for what we really want. Complaining about your problems never solves them. Only when you get clear about what you want, and are willing to ask for it, will you experience not only a lot less stress in your life, but greater success in your relationship, career and life. Here are five tips to help you on your way.
【小题1】________________
We often think our bosses, colleagues and even our friends can understand our thought even without being told. So when they don’t act as we’d like, we feel hurt and upset. For any relationship to develop, both parties have to communicate their needs. Whether it’s how you’d like your colleague to communicate with you about a work project, or how you’d like your boss to assess your work, it’s necessary to convey what you want.
【小题2】________________
When asking for what you really want, you will seldom, if ever, be given more than what you have the courage to ask for. So don’t weaken your requests to avoid being turned down. Think about what your ideal outcome would be and then confidently, courageously, ask for it. While you may not always get as much as you asked for, you will get more than you would have otherwise.
【小题3】________________
In the workplace, the biggest reason for unmet expectations is a lack of understanding of exactly what is expected. A request that holds water needs to make clear not just what you want, but also the time limit within which you want it. That is, both a clear “what” and “when”. For example, “Could you please get the monthly sales report to me by midday Friday?
【小题4】________________
Whether it’s asking your friend to show up on time, or asking your colleague to stop making jokes in your presence, every day, through what you say and do, you teach others how to treat you. Letting others know what you will （and will not）put up with and what you expect from them, is important to your wellbeing and success—at home and work.
【小题5】________________
In reality you won’t always get what you ask for. Your boss won’t always give you the pay raise you’d like and your parents may not agree to mind your three kids every second weekend. When people say no, you can take it really personally and decide never to speak to them again—or you can accept it graciously and move on. At least now you know where you stand and can plan accordingly.
Asking for less than you really want—from yourself, from others and from life—doesn’t serve anyone. Remember that fortune favors the bold. So make bigger, better, bolder requests, and ask for what you really want. Who knows…you might just get it!

You can’t hide a natural disaster from children, so how do we prepare them for it? First of all, you should explain to them that acts of nature aren’t necessarily disasters but can become one. These may include floods, hurricanes, tornadoes, winter storms, wild fires, and earthquakes. The way to prepare children for these disasters is to educate them about what each type is and then make it fun by making them “Disaster Masters” or whatever title you can think of.
Making them a Disaster Master won’t be easy. They must know what’s in a disaster emergency kit(工具箱) and why it’s included. You can get your friends involved, too. If your friends have children, they may want to be involved in your emergency preparations. Make it a group project. This is the opportunity for everyone to become familiar with the equipment.
We have to be aware of our conduct and the way we react to stress. The children will be easily influenced by your attitude and demeanor. The calmness, steady manner, and good humor of your spouse (配偶) and you will go a long way toward the easing or the reduction of stress.
Explain to them what they’re likely to encounter or see and describe how people may react. Disasters can come and go very quickly and generally don’t last long. If you must stay away from home, try to get into a routine quickly and encourage them to make new friends. Let them know they can look to their parents and other adults if they become scared or confused. And it’s important to let them know it’s OK to cry during a disaster.
It’s sometimes helpful to let the children draw pictures of what they’ve experienced. Encourage them to write what they learned and what could have been done better. Save the story. Make it part of a documented family history!
【小题1】This passage was written mainly to tell us about ______.

Have you ever noticed someone "talking" to them-selves? What did you think? The word "crazy" probably came to your mind. Wait a minute, though. Maybe they’re doing something meaningful.
Speaking practice can be effective in many different forms when people learn English or another foreign language. Imitating the speech of others is proven to be highly effective in developing a native speaker’s level of fluency in a language. Actually you’ve already proven that to your-self.
How? That’s how you learned your first language! Whether it was English, Spanish, French or some other language, you "imitated" your mother, father, other family members, friends, teachers and whoever else was around making "talking" noises at you as you formed your first communicative language skills.
So don’t think those who are talking to themselves are "crazy". At least don’t do so until you’ve tried it for your-self, in English or in your new foreign language.
As you go through your day, in English or your new foreign language, tell yourself what you’re doing at the moment and what you’re going to do during the day.
"Which of these shirts, ties, etc. should I wear today? Not this one, I wore it just last week. Maybe this one, but I don’t like this color with the pants. Let’s try another one," you might say as you are getting dressed.
If you live alone, you can talk aloud whenever you want without disturbing others. If you don’t live alone, however, then first explain to your family or roommates what you’ll be doing, to avoid a quiet phone call to the local psychiatrist (精神病学家).
【小题1】The author wrote the passage mainly to _______.

An inventor seeks to create a new product that serves a specific need and fulfills a role that other products do not. Sometimes an inventor comes up with a wholly new idea, but more often inventions are simply improvements on an older design. With a little imagination and creativity (创造力), an old idea can suddenly become something new.
However, creating a new invention means much more than having a brilliant idea. A good designer follows the design process: identifying the challenge, researching and brainstorming ideas(集思广益), designing a solution, testing and evaluating the ideas, and finally building the product. Designers also use science, math, technology, and engineering to design a tool that satisfies the need they identified.
Anyone can be an inventor —even kids! For example, Chester Greenwood was just fifteen years old when he invented a product that changed his life. In fact, his idea was so good that his invention supported him for the rest of his life. You may not know his name, but you probably know his invention —earmuffs (保暖耳罩)!
The inspiration for his earmuff design came to Chester when he was ice-skating. His ears were cold, and he decided to find a way to keep them warm. With the help of his grandmother, he made a new product to protect his ears and at the age of eighteen, Chester patented his earmuff design.
Many other famous inventors started young as well. Margaret Knight —the inventor of the flat-bottomed brown paper bag —is said to have created a safety device for textile looms(织布机) when she was just twelve years old. Another example is Thomas Edison, one of the greatest inventors in history, who applied for his first patent when he was just twenty-one years old. Over the course of his life, Thomas Edison patented a total of 1,093 inventions!
【小题1】In most cases, an invention ________ according to the first paragraph.
