Catch yourself daydreaming while washing the dishes again? If this happens often you probably have a pretty capable working memory and a sharper brain, new research suggests.
This mind wandering, it seems, actually gives your working memory a workout. Working memory is the mental work space that allows the brain to juggle multiple thoughts at the same time. The more working memory a person has, the more daydreaming they can do without forgetting the task at hand.
Researchers studied groups of people from the University of Wisconsin－Madison community, ranging in age from 18 to 65. The volunteers were asked to perform simple tasks, like pressing a button every time they took a breath or clicking in response to a letter popping up on a computer screen; these tasks were so easy that their minds were likely to wander, the researchers figured.
The researchers checked in periodically, asking the participants if their minds were on task or wandering. When the task was over, they measured each participant's working memory capacity by having them remember letters while doing math questions. Though all participants performed well on the task, the researchers noticed that the individuals who indicated their minds had wandered more than others also scored higher on the working memory test.
“What this study seems to suggest is that, when circumstances for the task aren't very difficult, people who have additional working memory resources allocate them to think about things other than what they're doing，” said Jonathan Smallwood, a study researcher of the Max Planck Institute for Human Cognitve and Brain Science.
When our minds run out of working memory, these off－topic thoughts can take the main stage without us consciously meaning them to; for instance, arriving at home with no memory of the actual trip, or suddenly realizing that they've turned several pages in a book without understanding any of the words.
“It's almost like your attention was so absorbed in the mind wandering that there wasn't any left over to remember your goal to read，” study researcher Daniel Levinson, said in a statement.
People with overall higher working memory were better able to stay focused when the task at hand required it. Those who had low working memory often had their thoughts drift away from the task, and did less well at it.
The findings add to past research suggesting these mind drifts can be positive moments. For instance, daydreaming has often been associated with creativity—researchers think that our most creative and inventive moments come when daydreaming. It's likely that the most intelligent among us also have high levels of working memory, Levinson noted.The word “juggle” in the second paragraph can be replaced by “________”．
| A．handle | B．search | C．understand | D．distribute |

| B．On the working memory test, people with wandering minds will get high score. |
| C．Absorbed in the mind wandering, your attention left no space for your goal. |

Can you imagine learning by playing games. To be sure, only children experienced some things differently from those with sisters and brothers. Many feel more pressure to succeed. They also tend to look only to their parents as role models in the absence of brothers and sisters.
In India, 10-year-old Saviraj Sankpal founded a support group for the tiny minority of only children. Among other things, the group does volunteer work to counter (or be against) the myth that they are not responsible. "People think we're treated too kindly and ruined," says Sankpal, a computer engineering student. "But I'd like to remind them how lonely it can get."
Most only children, however, say they wish for sisters or brothers only when it comes to caring for aging, unhealthy parents. Britain's David Emerson, coauthor of the book The Only Child, says that such a person bears terrible burden in having to make all the decisions alone. Emerson knows from experience: After his father died, he chose to move his elderly mother from their family home, where she was vulnerable to (or easy to be attacked by) house breakers, to a new one with more security." The move was quite hard on her, and she might feel that I pushed her into it," he says,". After all, I am left with that responsibility."
In the future, more and more only children will likely face similar choices. With working mothers increasing, many families are finding they simply don't have the time, money or energy to have more than one child. As only children become common, perhaps the world will realize that the Charge made against them is unjust.It can be inferred from the passage that the author's attitude towards only children is _______.

Researchers in the psychology department at the University of California at Los Angeles (UCLA) have discovered a major difference in the way men and women respond to stress. This difference may explain why men are more likely to suffer from stress-related disorders.
Until now, psychological research has maintained that both men and women have the same "fight-or-flight" reaction to stress. In other words, individuals either react with aggressive behavior, such as verbal or physical conflict ("fight"), or they react by withdrawing from the stressful situation ("flight"). However, the UCLA research team found that men and women have quite different biological and behavioral responses to stress. While men often react to stress in the fight-or-flight response, women often have another kind of reaction which could be called "tend and befriend." That is, they often react to stressful conditions by protecting and nurturing their young ("tend"), and by looking for social contact and support from others - especially other females ('befriend").
Scientists have long known that in the fight-or- flight reaction to stress, an important role is played by certain hormones(激素) released by the body. The UCLA research team suggests that the female tend-or-befriend response is also based on a hormone. This hormone, called oxytocin, has been studied in the context of childbirth, but now it is being studied for its role in the response of both men and women to stress. The principal investigator, Dr. Shelley E. Taylor, explained that "animals and people with high levels of oxytocin are calmer, more relaxed, more social, and less anxious." While men also secrete(分泌）oxytocin, its effects are reduced by male hormones.
In terms of everyday behavior, the UCLA study found that women are far more likely than men to seek social contact when they are feeling stressed. They may phone relatives or friends, or ask directions if they are lost.
The study also showed how fathers and mothers responded differently when they came home to their family after a stressful day at work. The typical father wanted to be left alone to enjoy some peace and quiet. For a typical mother, coping with a bad day at work meant focusing her attention on her children and their needs.
The differences in responding to stress may explain the fact that women have lower frequency of stress-related disorders such as high blood pressure or aggressive behavior. The tend-and-befriend regulatory(调节的) system may protect women against stress, and this may explain why women on average live longer than men.The UCLA study shows that in response to stress, men are more likely than women to _____ .
| A．turn to friends for help | B．solve a conflict calmly |
| C．find an escape from reality | D．seek comfort from children |

Phil White has just returned from an 18,000-mile, around-the-world bicycle trip. White had two reasons for making this epic journey. First of all, he wanted to use the trip to raise money for charity, which he did. He raised £70,000 for the British charity, Oxfam. White's second reason for making the trip was to break the world record and become the fastest person to cycle around the world. He is still waiting to find out if he has broken the record or not.
White set off from Trafalgar Square, in London, on 19th June 2004 and was back 299 days later. He spent more than l,300 hours in the saddle（车座）and destroyed four sets of tyres and three bike chains. He had the adventure of his life crossing Europe, the Middle East, India, Asia, Australia, New Zealand and the Americas. Amazingly, he did all of this with absolutely no support team. No jeep carrying food, water and medicine. No doctor. Nothing! Just a bike and a very, very long road.
The journey was lonely and desperate at times. He also had to fight his way across deserts, through jungles and over mountains. He cycled through heavy rains and temperatures of up to 45 degrees, all to help people in need. There were other dangers along the road. In Iran, he was chased by armed robbers and was lucky to escape with his life and the little money he had. The worst thing that happened to him was having to cycle into a headwind on a road that crosses the south of Australia. For 1,000 kilometres he battled against the wind that was constantly pushing him. This part of the trip was slow, hard work and depressing, but he made it in the end. Now Mr. White is back and intends to write a book about his adventures.
When Phil White returned from his trip, he________.
| A．broke the world record | B．collected money for Oxfam |
| C．destroyed several bikes | D．travelled about 1,300 hours |
What does the word "epic" in Paragraph l most probably mean _____.
| A．Very slow but exciting. | B．Very long and difficult. |
| C．Very smooth but tiring. | D．Very lonely and depressing. |

| B．experienced the extremes of heat and cold |
| C．managed to ride against the wind in Australia |
