Sports shoes that out whether their owner has enough exercise to warrant time in front of the television have been devised in the UK.

The shoes―named Square Eyes―contain an electronic pressure sensor and a tiny computer chip to record how many steps the wearer has taken in a day. A wireless transmitter passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves, based on the day’s efforts.

The design was inspired by a desire to fight against the rapidly ballooning waistlines among British teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at Brunel University to London, UK. “We looked at current issues and childhood overweight really stood out,” she says. “And I wanted to tackle that with my design.”

Once a child has used up their daily allowance gained through exercise, the television automatically switches off. And further time in front of the TV can only be earned through more steps.

Swan calculated how exercise should translate to television time using the recommended daily amounts of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television. So, every 100 steps recorded by the Square Eyes shoes equals precisely one minute of TV time.

Existing pedometers (计步器) normally clip onto a belt or slip into a pocket and keep count of steps by measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. “It is possible, but it would be a lot of effort,” she says. “That was one of my main design considerations.”

71.According to Swan, the purpose of her design project is to ________.

A.keep a record of the steps of the wearer

B.deal with overweight among teenagers

C.enable children to resist the temptation of TV

A.The exact number of steps to be taken.

B.The precise number of hours spent on TV.

C.The proper amount of daily exercise and TV time.

D.The way of changing steps into TV watching time.

74.Compared with other similar products, the new design ________.

A.makes it difficult for lazy teenagers to cheat

B.counts the wearer’s steps through shaking

C.records the sudden movement of the wearer

D.sends teenagers’ health data to the receiver

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.

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

2.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

3.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.

4.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.
