Article: Weighing too much can damage your health, and obesity is a growing problem for both kids and adults around the world. Sleep might be one answer to the problem. A new study has found that elementary school students who slept too little were more likely to gain pounds. Past studies have shown a link between sleeping less and weighing more, but scientists have had a tough time determining"which came first, the chicken or the egg,"says Julie C. Lumeng of the University of Michigan in Ann Arbor. In other words, it hasn't been clear whether kids who weigh too much have trouble sleeping, or whether sleeping less leads to weight gain. Both scenarios seemed equally possible. To get a better idea of which causes which, Lumeng and her colleagues interviewed the parents of 785 third graders from around the United States. The parents answered questions about how well their kids slept that year. Three years later, the parents answered the same questions. By sixth grade, 18 percent of kids involved in the study were obese. The scientists found no relationship between weight and the students' race or gender. It also didn't matter how strict their parents were, or whether they were boys or girls. Obesity struck all of these groups equally. Instead, sleep seemed to be the key factor. Over the 3 years of the study, the children averaged a healthy 9.5 hours of sleep a night. Some kids, however, slept a lot more -- or less -- than others. For the sixth graders, every hour of sleep above the 9.5-hour average was linked to a 20 percent lower risk of being obese. Sleep appeared doubly important for the third graders. Every extra hour of sleep they got was linked to a 40 percent drop in obesity. Question: What is the suitable title for the passage? Yes or no, is the answer "Sleeping less increases the risk of obesity"?
No

Article: Have you ever had travel problems because your airplane was late? It is a common problem and it is getting worse. Airport delays make people angry and cost the country billions in lost work time. The Federal Aviation Administration (FAA) is the government agency that oversees air travel. They studied the problem of airline delays. They found eleven major problems and suggested eleven ways to fix them. Some of the problems are caused because different regions of the country do things differently. The regions don't talk to each other enough. Some of them need new computers. Also, more planes are flying. A strong economy has more people using airplanes to get around. Airplanes are a form of mass transportation now, like trains and buses were in the past. More planes in the airport cause delays. The airport in San Francisco is a good example. It is growing fast. Many people go through San Francisco to get to other places around the world. Ron Wilson of the San Francisco International Airport says, "If you've got 18 flights that all want to take off at 8:00 am and you're on the 18thplane in line, you're going to be 40 minutes late." Weather is another main reason for delays. Weather causes about 70% of delays. Fog or freezing rain can cause delays. The first thing the FAA wants to do is take control away from the regions during heavy traffic times and bad weather. A national center would make decisions on things that affect the whole country. The FAA also wants to put more distance between planes in the sky when the weather is bad. This rule could cause even more delays. The FAA knows that their solutions will not solve the problems with airport delays. But, they hope to make things better. There are just too many planes, too few traffic controllers, and not enough new technology. Question: Which of the statements best gives the idea of the passage? Yes or no, is the answer "Airport delays are on the rise."?
No

Q: Article: About 35 percent of British adults sleep with teddy bears. Many more share a bed with a partner or spouse. Others still co - sleep, alongside children in a family bed. But lying with your iPad? A recent survey by marketing agency Rosette found that 68 percent of tablet owners use the device in the bedroom, more than in any other location. The living room took a close second place, at 63 percent, reports AdAge. com, and only 45 percent of respondents said they use their tablets on the go. But bringing devices into the bedroom is a bad idea, if quality rest is your goal. One of the most important factors of sleepiness is darkness, which signals to the brain that it's time to start speeding up production of the sleep - inducing hormone melatonin. But as the New York Times points out, in our modern world, we are exposed to light long after the sun sets. While any type of light can disturb your sleep, the blue wavelength light given off by cell phones, laptops, tablets and other gadgets is particularly troublesome. Research shows that this blue light causes alertness so decisively that it can actually be used to fight tiredness. According to the National Sleep Foundation, 95 percent of Americans use some device, whether it's a TV, laptop, cell phone or other products, within an hour of killing time. "Artificial light exposure between dusk and the time we go to bed at night push our sleeping sense to a later hour - making it more difficult to fall asleep," said Charles Czeisler, Ph. D. , M. D. , chief of the division of sleep medicine at Brigham and Women's Hospital in Boston. Instead, experts recommend turning off all devices an hour before bedtime and finding another method for relaxation, like reading a book, taking a warm bath or performing a series of calming yoga poses. It's also a good idea to exercise and lay off the caffeine several hours before bedtime. Question: According to a recent survey, most tablet owners use their iPad _ . Yes or no, is the answer "in the bedroom"?
A: No

Article: In modern society, receiving systematic college education seems a necessary way for success as a graduate from first-class university may always get more opportunities than others. However, if it is gold, it will shine one day. In this article, we will get to know three most successful people in U.S. who never finished their college education. Following experiences of these successful _ s may give you some inspiration. 1. Bill Gates Harvard's campus paper "Harvard Crimson" called Bill Gates "Harvard's most successful dropout," while the rest of the world preferred to name him "the world's richest man" for more than a decade. Now, even not on the top, he is still among the list of the world's wealthiest people.Gates entered Harvard in the fall of 1973. Two years later, he dropped out to found Microsoft with friend Paul Allen. And in 2007, he finally received an honorary doctorate from Harvard. 2. Steve Jobs The iPad, even Buzz Lightyear probably wouldn't have existed if Steve Jobs stayed in school. Because his family couldn't afford his college education, Jobs had to drop out of Reed College just after entering for 6 months. Then he found Apple, NeXT Computer and Pixar, which had made great influences on development of modern technique and culture. However, this wizard thought that his brief college education was not worthless. 3. Frank Lloyd Wright As the America's most celebrated architect, Wright spent more time on designing colleges rather than attending classes in them. Once spent one year in the University of Wisconsin-Madison, then he left for Chicago and started to learn from Louis Sullivan, the "father of modernism." Wright' s splendid resume included more than 500 works, most famous of which are Fallingwater and New York City's Solomon R. Guggenheim Museum. Question: What does the author want to tell us in this passage? Yes or no, is the answer "Even without college education, one can still achieve success with one's hard work."?
No
