Q: Article: A recent study suggests that teens' relationship with parents, friends and teachers may have a lot to do with why they don't get a good night's sleep. David Maume, a sociologist and sleep researcher, analyzed federal health data, which interviewed 974 teenagers when they were 12, and then again at 15. He found that family dynamics   have much to do with how well kids sleep. Teens, who had warm relations with their parents and felt like they could talk to them or their parents were supportive of them, tended to sleep better. However, families that were going through a divorce or a remarriage tended to affect teens' sleep. And problems at school also affected teens' sleep. Feeling safe at school and having good relations with teachers tended to promote better sleep. As did good relationships with friends. Kids who took part in sports or other positive social activities or shared similar academic goals with their friends were also more likely to get a good night's sleep. These add up to what makes lots of sense: a general feeling of well-being helps teens sleep. If we're happy and contented, we're much more likely to sleep better than if we're sad and anxious. Now, of course, teens can hardly resist being drawn to their computers and social networking. Maume also found that when parents were strict not only about bedtime, but also about limiting technology, kids slept better. It's a finding that seems obvious, but parents really do matter when it comes to health habits of their teenagers. Clearly, teenagers aren't getting 9 to 10 hours a night, which puts them at risk for all the consequences of lack of sleep, including poor academic performance, colds and stress. 
 Question: What is the passage mainly about? 
 Options: (A) Teens' sleep is linked to their relationship with people around them. (B) Lack of adequate sleep puts teens at risk of many bad consequences. (C) Modern technology has something to do with teens' sleep problems. (D) It is necessary for teens to join in sports and positive social activities.

Q: Article: NBA commissioner David Stern was in Orlando on Thursday night, getting ready for Sunday's All-Star Game. Of course, all he could talk about was the only player anyone wants to talk about these days: New York Knicks guard Jeremy Lin. Hours before Lin took the court against the Heat, a few hundred miles South down I-95 in Miami, Stern told reporters that Lin's instant popularity hasn't ever been matched in sports history, not even by Sunday's biggest names, LeBron James or Kobe Bryant. The Associated Press had the details. "I haven't done a calculation, but it's fair to say that no player has created the interest and the craze in this short period of time, in any sport, that I'm aware of like Jeremy Lin has," Stern said Thursday. Lin, an undrafted guard from Harvard, has become the NBA's biggest story since coming off the Knicks' bench earlier this month to lead them to nine wins in 11 games heading into their matchup with Miami on Thursday night. With Lin's popularity in Asia as the league's first American-born player of Chinese or Taiwanese descent, and with the religious community because of his strong Christian faith, Stern says he's "never quite seen anything like" the attention on Lin. "It's fascinating," Stern said after the All-Star Jam Session opening ceremonies. The top five videos on NBA.com since Feb. 4, when Lin joined the circulation, are all Lin or Knicks related. Lin went from 190,000 followers on Sina, China's version of Twitter, on Feb. 2 to more than 1 million as of Feb. 16. Indeed, Lin's popularity is so _ that the NBA made a late list switch to ensure his participation in the Rising Stars Challenge on All-Star Saturday, a game that includes the NBA's best rookies and sophomores. Lin is in such high demand that all of the game's other participants will meet with the media following a team practice on Friday while Lin will have his own, separate press conference later in the night. This is Jeremy's world, folks. We're all just living in it. Even David Stern and the rest of the league's All-Stars, at least for the moment. 
 Question: The following statements about Jeremy Lin's instant popularity are true EXCEPT that   _  . 
 Options: (A) Jeremy Lin led New York Knicks to win all the recent games this month (B) David Stern said Lin was the only instant popular player in NBA's history (C) Lin has become the NBA's greatest story though he was an undrafted guard (D) no player has created the interest and the enthusiasm in such a short period of time

Q: Article: I must have been about fourteen then, and I put away the incident from my mind with the easy carelessness of  youth. But the words, Carl Walter spoke that day, came back to me years later, and ever since have been of great value to me. Carl Walter was my piano teacher. During one of my lessons he asked how much practicing I was doing. I said three or four hours a day. "Do you practice , an hour at a time?" "I try to." "Well, don't," he exclaimed. "When you grow up, time won't come in long stretches.    Practice in minutes, whenever you can find them five or ten before school, after lunch, between household tasks. Spread the practice through the day, and piano-playing will become a part of your life." When I was teaching at Columbia, I wanted to write, but class periods, theme-reading, and committee meetings filled my days and evenings. For two years I got practically nothing down on paper, and my excuse was that I had no time. Then I remembered what Carl Walter had said. During the next week I conducted an experiment. Whenever I had five minutes unoccupied, I sat down and wrote a hundred words or so. To my astonishment, at the end of the week I had a rather large manuscript ready for revision, later on I wrote novels by the same piecemeal method. Though my teaching schedule had become heavier than ever, in every day there were idle moments which could be caught and put to use. I even took up piano--playing again, finding that the small intervals of the day provided sufficient time for both writing and piano practice. There is an important trick in this time--using formula: you must get into your work quickly. If you have but five minutes for writing, you can't afford to waste four chewing your pencil. You must make your mental preparations beforehand, and concentrate on your task almost instantly when the time comes. Fortunately, rapid concentration is easier than most of us realize. I admit I have never learnt how to let go easily at the end of the five or ten minutes. But life can be counted on to supply interruptions. Carl Walter has had a tremendous influence on my life. To him I owe the discovery that even very short periods of time add up to all useful hours I need, if I plunge in without delay. 
 Question: Which of the following statements is true? 
 Options: (A) The writer didn't completely take the teacher's words to heart at first. (B) Carl Walter has had a great influence on the writer's life since he became a student. (C) The writer owes great thanks to his teacher for teaching him to work in long stretches. (D) Rapid concentration is actually more difficult than most people imagine.
