Article: WELLINGTON, September 19 (Xinhua) -- If your teenage son won't get out of bed in the morning, then take comfort from the fact that he might be sleeping his way to a healthier future, according to a new research from New Zealand. Researchers in human nutrition at the University of Otago have found that teenage boys who sleep less have more body fat when compared to girls, for whom lack of sleep has no noticeable effect on their body fat ratios. The study of 386 boys and 299 girls aged 15 to 18 found that average-sized 16-year-old boy weighing 69.5 kg and 176 cm tall, who slept for eight hours a day, had a waist size l.8 cm bigger and l.6 kg, or 9 percent, more body fat than the average-sized boy who slept 10 hours a day. "The boys who slept eight hours a day would also have l.8 kg more lean (bone and muscle) mass compared to the boys who slept 10 hours, but that's only a 1.4-percent increase, compared to the 9- percent increase seen in body fat," said lead researcher from the Department of Human Nutrition, Dr. Paula Skidmore. "Our results suggest that for older teenage boys, making sure that they get enough sleep may help to maintain a healthier body. It seems to be that, within reason, the more sleep the better for boys," Skidmore said in a statement Thursday. "It was unexpected that we did not find the same result in girls, who may actually be more aware of their diet and more in tune with a healthier lifestyle." The researchers ruled out the effects of food choice and number of screens, such as televisions, games and consoles, which the teenagers had in their bedrooms. Question: Who would be the most pleased to hear the news? Yes or no, is the answer "Boys."?
No

Article: Some people are lucky enough to be born with a good sense of direction and even if they have only visited a place once, they will be able to find it again years later. I am one of those unfortunate people who have poor sense of direction and I may have visited a place time after time but I still get lost on my way there. When I was young I was so shy that I never dared ask complete strangers the way and so I used to wander round in circles and hope that by some chance I would get to the spot I was heading for. I am no longer too shy to ask people for direction, but I often receive replies that puzzle me. Often people do not like to admit that they didn't know their hometown and will insist on telling you the way, even if they do not know it; others, who are anxious to prove that they know their hometown very well, will give you a long list of directions which you can not possibly hope to remember, and still others do not seem to be able to tell between their left and their right and you find in the end that you are going in the opposite direction to that in which you should be going. If anyone ever asks me the way to somewhere, I always tell them I am a stranger to the town in order to avoid giving them wrong direction but even this can have embarrassing results. Once I was on my way to work when I was stopped by a man who asked me if I would direct him the way to the Sunlight Building. I gave my usual reply, but I had not walked on a few steps when I realized that he had asked for directions to my office building. However, at this point, I decide it was too late to turn back and search for him out of the crowd behind me as I was going to meet with someone at the office and I did not want to keep him waiting. Imagine my embarrassment when my secretary showed in the very man who had asked for directions of my office and his astonishment when he recognized me as the person he had asked. Question: How did the visitor feel when he was showed into the very room? Yes or no, is the answer "He felt astonished."?
No

Article: An Australian man has beaten 75 other contestants from around the world to win a race up the stairs of the world's tallest building, Taipei 101. Paul Crake,30, ran up 91 floors containing 2,046 steps in 10 minutes, 29 seconds. Mr. Crake, who has won a similar race up the Empire State Building five times, won $5,920 in prize money. The women's race was won by Austrian Andrea Mayr, who finished in 12 minutes,38 seconds and also won a $5,920 prize. Austrian Rudolf Reitheiger, who beat Mr. Crake in this year's Empire State Building Race, came second in the men's competition. Mr. Crake and Ms. Mayr missed out on the offer of $30,000 for completing the grueling race in under 10 or 12 minutes respectively. A further 1,001 people took part in a so-called "self-challenging" race up the skyscraper. Taipei 101 is 508 meters tall and was finished in 2003, although Chinese developers have said Shanghai's World Financial Center will be taller when completed in 2007. "Tower-running" races take place up the tallest buildings and structures across the world. The Sears Tower in Chicago, the CN Tower in Toronto and the Azrieli Tower in Tel Aviv have all held recent events. Runners also race up the longest staircase in the world-the service staircase for the Niesenbahn railway near Spiez, Switzerland, which has 11,674 steps. At event for the long--distance stairway runners also takes place in Radebeul, Germany, where competitors run up 397 stairs 100 times to equal the height of Mt everest. Question: What's main idea of this passage? Yes or no, is the answer "Races up the stairs of the tallest buildings and structures across the world"?
No

Article: There are robots all around us,Some do very complicated jobs like flying airplanes and driving subway trains. And some do a simple job. When an automatic washing machine is switched on, water pours in. The machine waits until the water is hot before washing the clothes. It does this by "feedback". Information about what is happening is "feedback"into the robot to tell it what to do next. Our eyes,ears and other senses are our feedback. They tell us what is going on around us. So robots are like people in two ways:They work and they have feedback. There are robots all around, making our lives easier. Some of them, like the pocket calculator, can work much more quickly than human beings can. And they rarely make mistakes. In some ways robots are better than people. They work quickly, but do not make mistakes. They do not get bored doing the same job over andover again. And they never get tired. Robots are very useful in factories. They can be taught to do many different jobs. First their electronic brains must be shown how the job is done. A person moves the robot's"arm"and"hand"through each part of the job. The robot's brain remembers each move. When the robot is put to work on its own, its brain controls the rods, wheels and motors which move its arm. When the robot is needed for a new job, its electronic memory is"wiped clean."Then it is taught how to do its new task. If the robot's hand stops working, or if something gets in the way, it cannot do the next part of the job. So it stops and signals for help, then a human engineer repairs it. The most"intelligent"robots can move and see. Their eyes are cameras. Their metal fingers can feel shapes and even find out how hot and cold objects are. These robots have computer brains, linked to their eyes and fingers, which control their actions. Question: Since people like what robots do, what do you think this means for the future? Yes or no, is the answer "More and better robots will be built."?
No
