Article: Have you ever been stuck for hours on a hard math problem? 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: . It was believed that daydreaming _ . Yes or no, is the answer "was a waste of time when the mind was shut off"?

Article: Having returned from her round trip, the angry woman stood outside the ticket office of the station. "The railway should pay me backPS12, so you owe me the money," she said to Harry Jenks, the young man who was working at the office. "You sold me a ticket for May 22nd, but there was no ship from Jersey that night. So my daughter and I had to stay in a hotel. It cost me PS12." Harry was worried. He remembered selling the woman a return ticket. "Come into the office, Madam," he said politely, "I'll just check the Jersey timetable for May 22nd." The woman and her little girl followed him inside. She was quite right, as Harry soon discovered. There was no sailing on May 22nd. How could he have made such a careless mistake? He shouldn't have sold her a ticket for that day. Wondering what to do, he smiled at the child. "You look sun burnt," he said to her, "Did you have a nice holiday in Jersey?" "Yes," she answered, shyly, "The beach was lovely. And I can swim, too!" "That's fine," said Harry. "My little girl can't swim a bit yet. Of course, she's only three..." "I'm four," the child said proudly, "I'll be four and a half." Harry turned to the mother. "I remember your ticket, Madam," he said, "But you didn't get one for your daughter, did you?" "Er, well..."woman looked at the child, "I mean... she hasn't started school yet. She's only four." "A four-year-old child must have a ticket, Madam. A child's return ticket to Jersey costs...let me see...PS13.50. So if the railway pays your hotel, you will owePS1.50. The law is the law, but since the fault was mine..." Question: According to the passage, we know that Harry was _ . Yes or no, is the answer "smart"?

Article: Many places in the world need more fresh water. Every country is trying to find ways to turn salt water into fresh. Why aren't there many factories like the Symi factory? In some places the sun is not hot enough. Or it does not shine every day. In such places other ways of heating sea water can be used. These ways cost more money, but they work faster than the sun. By boiling sea water with high heat a lot of fresh water can be made quickly. But heating is not the only way to get fresh water from salt water. Other ways are tried. One way is freezing. The fresh part of salt water freezes first. To get fresh water, the bits of ice are taken out. Which way is the best? The one that gives the most water for the least money.

That is why people in many dry places talk about Symi. Question: From the passage we know that fresh water _ . Yes or no, is the answer "is needed in every country"?
