Read the following article and select the best answer. 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.

Read the following article and select the best answer. Article: When you're a parent to a young child, you spend a lot of time talking about feelings: about having to share, about being disappointed because you may not have a cookie instead of broccoli , about the great injustice of a parent pressing the elevator button before the child has a chance to. And in a parenting culture that's increasingly concerned with centering children's needs above all else, mothers and fathers have become skillful at talking about their kids' feelings while masking their own. But new research suggests that parents who hide their negative emotions are doing their children, and themselves harm. A study published this month says that when parents put on a faux-happy face for their kids, they do damage to their own sense of wellbeing and authenticity. "For the average parent the findings suggest when they attempt to hide their negative emotion expression and overexpress their positive emotions with their children, it actually comes at a cost: doing so may lead parents to feel worse themselves," researcher Dr Emily Impett, says. It makes sense that parents often fall back on amping up the positivity for the sake of their children--there are a lot of things in the world we want to protect our kids from. But children are often smarter than we expect and are quite in tune with what the people closest to them--their parents--are feeling. There was a time about a year or so ago, for example, when I received some bad news over the phone; I was home with my four-year-old and so I did my best to put on a brave face. She knew immediately something was wrong though, and was confused. When I finally let a few tears out and explained that Mom heard something sad about a friend, she was, of course, just fine. My daughter patted my shoulder, gave me a hug, and went back to playing. She felt better that she was able to help me, and the moment made a lot more sense to her emotionally than a smiling mom holding back sobs. I was glad that I could feel sad momentarily and not have to work hard to hide... Question: The author mentioned the example of her daughter to illustrate _ . - children are not so clever as parents think - children can often understand parents' true feelings - it's meaningful for parents to always look positive - it's necessary to expose children to harmful things
(Answer)
children can often understand parents' true feelings

Read the following article and select the best answer. Article: Charles Dickens was one of the most beloved storytellers in the English language. His novels made him famous in his own time, and continue as classics in ours. Dickens began his literary career with almost no formal education. He was born in Landport, on Feb. 7, 1812, the second of eight children. When he was 12, his father was sent to debtor's prison. Dickens was forced to quit school and work in a London blacking factory. He would rework that terrible experience into his fiction for the rest of his life. "He was a social reformer," says actor Simon Callow, author of a new biography called Charles Dickens and the Great Theatre of the World. "He knew what poverty was. He knew what it was to be rejected, to be cast aside, to live in squalor ." And so Dickens wrote with great sympathy for the suffering of innocent and vulnerable children - characters like David Copperfield, Little Dorrit and the orphan, Oliver Twist: With his slice of bread in his hand, and his little brown parish cap on his head, Oliver was now led away from the wretched home, where one kind word or look never lighted the gloom of his infant days. Yet he burst into an agony of childish grief as the cottage gate closed after him. Wretched as were the little companions in,misery he was now leaving behind him, they were the only friends he had ever had. His first book Sketches by Boz came out in 1836. With the appearance of Oliver Twist in London periodicals in 1837, the 25-year-old Dickens became the most popular writer in England. But his first love was theater, and he considered becoming an actor. "When he was actually writing, he became his characters," says Peter Ackroyd, author of Dickens: Public Life and Private Passion. "He would get up from his desk, go over to the mirror and mouth the words - do the expressions, grimaces , whatever, and then laugh, chuckle to himself, then go back to his desk and write it down." Dickens created 989 named characters, which increased his popularity....
