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.

Article: Students often want to practice their English outside class. One of the best ways to practice your English is to speak to a foreigner. You may ask, "Is it okay to try to talk to foreigners I see in the street?" The answer is yes and no, but probably no! If you see a foreigner who looks lost, it is polite to ask him, "May I help you?" But, otherwise, you should probably let them get on with their business. Situations, however, do exist where it is quite all right to talk to foreigners. If a foreigner enters your school, classroom, office, shop or restaurant, for instance, feel free to ask him (for example): -- What is your name? -- Where do you come from? -- What do you think of Beijing? -- How long will you stay in Beijing? There are also situations where it's okay to talk to foreigners in public places. If you see a foreigner alone in a restaurant, bar or coffee shop, it may be appropriate to ask him or her: -- Is this seat free? -- Do you mind if I talk to you in English? You can probably help them if they are new in China and if they are alone, you may be able to make them feel more welcome. After a few such questions, you should know whether this person wants to talk to you or not. If they ask you similar questions, or if they give long, informative answers, you're in luck. If not, then give them their privacy. Talking to strangers is fun if you choose the right time and place.
