Working out can help teenagers boost their grades, a new study suggests. Adolescents who routinely engaged in moderate to vigorous（剧烈的）exercise showed long-term improvements in their academic performance, the British Journal of Sports Medicine study reported.
“Our study suggests that the effect of physical activity may be quite large,” John Reilly, a professor at the University of Strathclyde said. The researchers looked at a sample of about 5000 children who were involved in a long-term study that tracks children born in the UK between 1991 and 1992. When children reached 11 years old, their daily physical activity levels were measured using an accelerometer（加速器）for three to seven days. The device, similar to a pedometer（计步器）tracking the number of steps taken, recorded the average time children exercised, which was 29 minutes a day for boys and 18 for girls.
“The actual levels of daily physical activity at age 11 were quite low,” Mr. Reilly noted. The children had their academic performance tested at ages 11 and 13 with compulsory national tests for students, and also at 15 or 16 with the General Certificate of Secondary Education (GCSE) exam. The tests assessed the children’s abilities in English, math and science subjects. The results showed that the more children participated in moderate to vigorous physical activity, the higher their test scores were at age 11 in all three subjects. For girls, science scores were most strongly linked to exercise.
When children were tested again at age 13, their academic scores were still linked to how much they had exercised when they were 11 years old. By the time the youngsters took the GCSE exam, each 17-minute-per‑day increase in physical activity for the boys was linked to an improvement in their scores. Every additional 12-minute increase a day in exercise for the girls was also linked to an increased score, especially in the science category.
The researchers have called for more studies to look at the possible academic benefits that could be derived if students exercised the recommended 60 minutes or more a day.
1.What’s the study about?
A.The influence of exercise on students’ scores.
B.The secrets of students’ ranking high in class.
C.The causes of students’ participating in sports.
D.The ways of improving students’ physical conditions.

D.To record the number of calories students consume.
3.What do the study’s results show?

How can you help kids cope with(应对) stress? Proper rest and good nutrition can boost coping skills, as can good parenting. Make time for your kids each day. Whether they need to talk or just be in the same room with you, make yourself available.
Even as kids get older, quality time is important. It’s really hard for some people to come home after work, get down on the floor, and play with their kids or just talk to them about their day--especially if they've had a stressful day themselves. But expressing interest in your kids shows that they’re important to you.
Help your children cope with stress by talking about what may be causing it. Together, you can come up with a few solutions. For example, they should cut back on after-school activities, spending more time talking with parents or teachers, developing an exercise plan or keeping a journal.
You can also help by predicting stressful situations and preparing kids for them. For example, let a child know ahead of time ( but not too far ahead of time) that a doctor’s appointment is coming up and talk about what will happen there. Keep in mind, though, that younger kids probably won't need too much advance preparation. Too much information can cause more stress.
Remember that some level of stress is normal; let kids know that it’s okay to feel angry, scared, lonely, or anxious and that other people share those feelings.
When kids can’t or won’t discuss these issues, try talking about your own concerns. This shows that you’re willing to handle tough topics and are available to talk with them when they’re ready. If a child shows symptoms that concern you and is unwilling to talk, consult a counselor or other mental health experts.
Most parents have the skills to deal with their kids’ stress. The time to seek professional attention is when any change in behavior persists, when stress is causing serious anxiety on when the behavior is causing significant problems in functioning at school or at home.
1.What is the purpose of the text?
A. To share the author' s ideas on proper parenting.
B. To persuade parents to spend more time with kids.
C. To advise parents how to help kids deal with stress.
D. To seek different ways to help solve kids' problems.
2.What makes it difficult for parents to spare kids quality time?
A. Kids growing so fast.
B. Parents being tired out.
C. Kids losing interest in parents.
D. There being too much homework.
3.You are advised not to talk too much about a stressful situation in advance because .
A. it does no good to your kids
B. it doesn’t work in practice
C. your kids may lose interest
D. your kids don’t want to listen
4.What can we learn from Paragraph 5 ?
A. Normal people share the same feelings.
B. It is normal for kids to have some stress.
C. Kids should get rid of negative feelings.
D. Everybody feels angry, scared, lonely or anxious.

Parents who help their children with homework may actually be bringing down their school grades. Other forms of prenatal involvement, including volunteering at school and observing a child's class, also fail to help, according to the most recent study on the topic.
The findings challenge a key principle of modern parenting(养育子女) where schools except them to act as partners in their children's education. Previous generations concentrated on getting children to school on time, fed, dressed and ready to learn.
Kaith Robinson, the author of the study, said, "I really don't know if the public is ready for this but there are some ways parents can be involved in their kids' education that leads to declines in their academic performance. One of the things that was consistently negative was parents' help with homework." Robinson suggested that may be because parents themselves struggle to understand the task." They may either not remember the material their kids are studying now, or in some cases never learnt it themselves, but they're still offering advice."
Robinson assessed parental involvement performance and found one of the most damaging things a parent could do was to punish their children for poor marks. In general, about 20% of parental involvement was positive, about 45% negative and the rest statistically insignificant.
Common sense suggests it was a good thing for parents to get involved because "children with good academic success do have involved parents ", admitted Robinson. But he argued that this did not prove parental involvement was the root cause of that success." A big surprise was that Asian-American parents whose kids are doing so well in school hardly involved. They took a more reasonable approach, conveying to their children how success at school could improve their lives."
1.The underlined expression "parental involvement " in Paragraph 1 probably means .
A. parents' expectation on children's health
B. parents' participation in children's education
C. parents' control over children's life
D. parents' plan for children's future
2.What is the major finding of Robinson's study ?
A. Modern parents raise children in a more scientific way.
B. Punishing kids for bad marks is mentally damaging.
C. Parental involvement is not so beneficial as expected.
D. Parents are not able to help with children’s homework.
3.The example of Asian-American parents implies that parents should .
A. help children realize the importance of schooling
B. set a specific life goal for their children
C. spend more time improving their own lives
D. take a more active part in school management

Most American teenagers can’t wait
to get rid of their “mental mouth” nickname(绰号). They count down the days they can finally take their braces （牙箍）off. However, trendy teenagers in Indonesia, Malaysia and Thailand can’t wait to get them on, even if they don’t need them.Braces are the latest teenage fashion trend in Southeast Asia. Having a mouthful of metal has become so popular with Asian teens that there have been reports of man
y teens wearing fake （假冒的）braces. Many Asian beauty shops are now offering to put in cheap fake braces. There are even cheaper do-it-yourself braces such as “ Hello Kitty,” Mickey Mouse” or others for a price of around $100.Braces are considered a sign of wealth in Southeast Asia. A real set of braces in Bangkok, the capital city of Thailand, for example, will cost around $ 1,200, which is a large amount for the country with a GDP（国内生产总值）of $345 billion ( a billion is 1,000 million), compared to the US which had a GDP of $1,506 Trillion ( a Trillion is 1,000 billion) last year.
While Asian teens may think that their colorful fake braces are cool, experts say that these trendy fashion braces can cause illness and can even lead to death. According to the New York Daily News, fake fashion braces have already been linked to the deaths of two teens in Thailand.A 17-year-old in the northeast city of Khon Kaen died from heart failure caused by a thyroid infection （甲状腺感染）from a pair of fake fashion braces. Police also linked the death of another 14-year-old girl in Chonburi to a pair of fashion braces she had brought from an illegal shop.
Although the government is giving warnings about fake braces, the trend has been going strong for at least four years. What’s worse, the trend for fake braces shows no sign of slowing down.

A.Comfortable B. interesting
C. useless D. ugly
