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 Cognitive 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.

A. search B. understand C. handle D. foresee

2.What can be concluded from Jonathan Smallwood's words?

A. Absorbed in the mind wandering, your attention left no space for your goal.

Eat like a king in the morning, a prince at noon, and a peasant at night. This saying is all about the importance of breakfast. And now scientists can tell us just why it’s so important. According to a study carried out at Imperial College London, UK, skipping the first meal of the day not only means you eat more at lunch, but also that your brain wants to find more unhealthy foods.

The study suggests that there is a special part of our brain called the orbitofrontal cortex (眶额皮层), which plays an important part in making choices about what we eat. It is used for identifying the taste of food, especially when skipping breakfast. It is more likely to target high-calorie foods when you’re on an empty stomach.

Scientists did an experiment on this. Dr Tony Goldstone from Imperial College London, scanned (扫描) the brains of 21 men and women, around the age of 25. On the first day, these people skipped breakfast before the scans. On the second day, they had cereal (谷物), bread and jam as breakfast. After the scan on both days, they had their lunch.

When the volunteers had skipped breakfast, they ate around 20 percent more at lunch, compared with days when they had eaten breakfast. Their brain scans also showed the orbitofrontal cortex was especially responsive to high-calorie foods. “We believe that bit identifies the value of foods – how pleasant, how delicious something is,” Goldstone told The Guardian.

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

Any car accident is frightening, but an accident in which your vehicle is thrown into the water, with you trapped inside, is absolutely(绝对地) terrifying.

1. . However, most deaths result from fear, without a plan or understanding what is happening to the car in the water. By adopting a brace(支撑) position, acting decisively and getting out fast, you can save yourself from a sinking vehicle.

Brace yourself for impact (撞击力). As soon as you're aware that you're going off th e road and into a body of water, adopt a brace position. The impact could set off the airbag system in your vehicle, so you should place both hands on the steering wheel(方向盘) in the "ten and two" position.

Undo your seatbelt. 2. . Release the children, starting with the oldest first. Forget the cell phone call. Your car isn't going to wait for you to make the call.

3. . Leave the door alone at this stage and concentrate on the window. A car's electrical system should work for up to three minutes in water, so try the method of opening it electronically first. Many people don't think about the window as an escape choice either because of fear or misinformation about doors and sinking.

Break the window. If you aren't able to open the window, or it only opens halfway, you'll need to break it with an object or your foot. It may feel counter-intuitive (有悖常理的) to let water into the car. 4. .

Escape when the car has equalized. If it has reached the stage where the car has been filled with water and it has become balanced, you must move quickly and effectively to ensure your survival. 5. . While there is still air in the car, take slow, deep breaths and focus on what you're doing.

A. Open the window as soon as you hit the water.

B. This is the first thing to do, yet it often gets forgotten.

C. Surviving a sinking car is not as difficult as you think.

D. In short, if you know what to do in the water, you will be safe.

E. It takes 60 to 120 seconds for a car to be filled with water usually.

F. Such accidents are particularly dangerous to the risk of drowning(淹死).

G. But the sooner the window is open, the sooner you can escape directly through it.
