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 (动态) 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. What is the passage mainly about?
| 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. |
According to Maume’s analysis, who will probably have a poor night’s sleep?
| A．Teens who feel like talking with their parents. |
| B．Teens who have friends sharing their dreams. |
| C．Teens who feel contented about themselves. |
| D．Teens who lack a sense of security at school. |

Will it matter if you don't take your breakfast? Recently a test was given in the United States. Those tested included people of different ages, from 12 to 83. During the experiment, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast. The results show that if a person eats a proper breakfast, he or she will work with better effect than if he or she has no breakfast. This fact appears to be especially true if a person works with his brains. If a student eats fruit, eggs, bread and milk before going to school, he will learn more quickly and listen with more attention to class.
Opposite to what many people believe, if you don't eat breakfast, you will not lose weight. This is because people become so hungry at noon that they eat too much for lunch, and end up gaining weight instead of losing. You will probably lose more weight if you reduce your other meals.During the test, those who were tested were given ________.

In most parts of the world, many students help their schools make less pollution. They join “environment clubs”. In an environment club, people work together to make our environment clean.
Here are some things students often do.
No-garbage (垃圾) lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will choose the classes that make the least garbage and report them to the whole school.
No-car day. On a no-car day, nobody comes to school in a car. Not the students and not the teachers! Cars give pollution to our air, so remember: work jump, bike and run. Use your legs! It’s lots of fun..
Turn off the water! Did you know that some toilets can waste twenty to forty cubic(立方) meters of water an hour? In a year, that would fill a small river!

The nation's largest group of pediatricians(小儿科医生) on Monday urged its members to “firmly oppose boxing for any child or adolescent.”
In a statement, the American Academy of Pediatrics (AAP) said thousands of boys and girls take part in the sport in North America, despite risks of serious brain and facial injuries. The group’s position was approved by some experts.
“There is very little one can do in order to increase the chance of having a healthy brain when you get old,” said Dr. Hans Forstl, who has studied boxing injuries.
“ One of the best things you can do is avoid boxing.” He said.
According to the new statement, published in the journal Pediatrics, information from Canada shows a rise in boxing injuries over the past decade.
Pat Russo, a retired police officer who runs a boxing gym in Brooklyn, New York, said injuries are rare in amateur boxing. After 26 years and training thousands of kids, he has seen just one split lip among his students.
“ If the gym is run properly, injuries are at an absolute minimum,” Russo said. “Football is ten times more dangerous. While tennis or football might also help kids gain confidence, boxing holds a special attraction for children in poor neighborhoods, because it allows them to act tough while in trouble.”
Dr. Robert Cantu, a surgeon (外科医生) at Emerson Hospital in Concord, Massachusetts, said AAP’s attitude makes sense for upper-class and middle-class kids.
“ Clearly boxing is safer today than it was 20 or 30 years ago, but it is still a very risky activity,” he said.
“For kids in poor areas, however, the situation is different,” said Cantu. “ The most dangerous thing for the majority of people in boxing is just where they live. They are far safer in the ring (拳击场), even taking blows to the head, than they are out in the neighborhood.”The statement released by AAP was ___________.
| A．approved by Pat Russo |
| B．focused on professional boxing |
| C．based on Dr. Hans Forstl’s research |
| D．strongly against boxing for children |
What is Dr. Hans Forstl’s attitude towards boxing for children?
| A．Unconcerned | B．Supportive |

Pat Russo believes that boxing injuries are____________.
| A．still on the rise today |
| B．not a serious problem in his gym |
| C．not common in poor neighborhood |
| D．more dangerous than football injuries |
In the text, Dr. Robert Cantu expressed his concern about __________.
| A．brain injuries occurring in boxing matches |
| B．the development of boxing among children |
| C．the attitude of upper-class kids toward boxing |
| D．children’s security in poor neighborhood |
What is the text mainly about?
