If you sat there for some time you might eventually solve it, but scientists say that daydreaming might be a much better way to tackle difficult tasks. In fact, daydreaming has long been misunderstood. It's considered to be a bad thing and often associated with laziness. "We're harsh on ourselves if we catch ourselves mind wandering," says Professor Kalina Christoff from the University of British Columbia in Canada. But the truth is that some of the most important scientific discoveries came about because scientists allowed their minds to wander. For example, Albert Einstein began his theory of relativity when he daydreamed about riding a beam of sunlight to the edge of the universe. And now, research has shown that normal people can also improve their problems solving ability in the same way, reported The Telegraph. In a study, 145 people aged between 19 and 32 were asked to list as many unusual uses as possible for everyday objects. Some of them were given a 12-minute break while the others were not allowed any break from the task. People on the break did not simply relax--some of them were told to carry out a tiring memory task while others did an easier task. Scientists found that people who did the easier task were daydreaming a lot. They thought about personal issues in the past or in the future because their mind was at ease. After the break, all participants were asked to return once again to the task of listing unusual uses for everyday objects. It was found that daydreamers improved their performance by 40 percent, while all the other people, including those who didn't have a break and who did tiring tasks during the break, performed the same as before. "People think that when the mind wanders away, it just gets turned off--but we show the opposite," explained Christoff."A more playful attitude might allow you to call in more resources ." So when you are struggling to solve complicated problems, it might be better off if you switch to a... Question: . What did the scientists discover in the experiment? Options: A: People's minds turned off as they daydreamed. B: The group that were given hard memory tasks performed best. C: People who had a break showed improvement in the task. D: Daydreaming could improve people's problem-solving abilities.

One Saturday in 2014, Ms Woo held a paper cutting show at a shopping center near Washington. She got much fun and peace doing it. She hoped more people would enjoy it. Ms Woo began to study the art of paper cutting as a 14-year-old girl in her hometown in China. She said all the students at school had to learn paper cutting. But she had a deep love for it. So her teacher spent more time teaching her after class. Later, she won the second prize in a national painting and art competition. Ms Woo went to America after she finished collage in 2008. Soon after that, she took part in an activity to promote Chinese paper cutting. And then she was invited to show the art in many important activities."It is important to promote this art to Americans or anyone who is interested in it.Maybe it will make this art more popular."Woo said. From the art of paper cutting, people can know about Chinese cultural values, history and stories of people's life.
