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.
1.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.
2.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.
3.Para 5 functions as .

4.Parents are supposed to when their kids are growing up.
A. continue their broken marriage B. allow children to decide when to sleep
C. limit teens’ using new technology D. force teens to have 10 hours’ sleep daily

Exercise seems to be good for the human brain，with many recent studies suggesting that regular exercise improves memory and thinking skills．But an interesting new study asks whether the apparent cognitive benefits from exercise are real or just a placebo effect — that is，if we think we will be “smarter” after exercise，do our brains respond accordingly？The answer has significant implications for any of us hoping to use exercise to keep our minds sharp throughout our lives．
While many studies suggest that exercise may have cognitive benefits，recently some scientists have begun to question whether the apparently beneficial effects of exercise on thinking might be a placebo effect．So researchers at Florida State University in Tallahassee and the University of Illinois at Urbana Champaign decided to focus on expectations，on what people anticipate that exercise will do for thinking．If people’s expectations jibe (吻合) closely with the actual benefits，then at least some of those improvements are probably a result of the placebo effect and not of exercise．
For the new study，which was published last month in PLOS One，the researchers recruited 171 people through an online survey system，they asked half of these volunteers to estimate by how much a stretching and toning regimens (拉伸运动) performed three times a week might improve various measures of thinking．The other volunteers were asked the same questions，but about a regular walking program．
In actual experiments，stretching and toning program generally have little if any impact on people’s cognitive skills．Walking，on the other hand，seems to substantially improve thinking ability．
But the survey respondents believed the opposite，estimating that the stretching and toning program would be more beneficial for the mind than walking．The estimates of benefits from walking were lower．
These data，while they do not involve any actual exercise，are good news for people who do exercise．“The results from our study suggest that the benefits of aerobic exercise are not a placebo effect,” said Cary Stothart，a graduate student in cognitive psychology at Florida State University，who led the study．
If expectations had been driving the improvements in cognition seen in studies after exercise，Mr．Stothart said，then people should have expected walking to be more beneficial for thinking than stretching．They didn’t，implying that the changes in the brain and thinking after exercise are physiologically genuine．
The findings are strong enough to suggest that exercise really does change the brain and may，in the process，improve thinking，Mr．Stothart said．That conclusion should encourage scientists to look even more closely into how，at a molecular level，exercise remodels the human brain，he said．It also should encourage the rest of us to move，since the benefits are，it seems，not imaginary，even if they are in our head．
1.Which of the following about the placebo effect is TRUE according to the passage？
A．It occurs during exercise．
B．It has cognitive benefits．
C．It is just a mental reaction．
D．It is a physiological response．
2.Why did the researchers at the two universities conduct the research？
A．To discover the placebo effect in the exercise．
B．To prove the previous studies have a big drawback．
C．To test whether exercise can really improve cognition．
D．To encourage more scientists to get involved in the research．
3.What can we know about the research Cary Stothart and his team carried out？
A．They employed 171 people to take part in the actual exercise．
B．The result of the research removed the recent doubt of some scientists．
C．The participants thought walking had a greater impact on thinking ability．
D．Their conclusion drives scientists to do research on the placebo effect．

高三英语单项填空简单题查看答案及解析
Personal money-management website Mint.com suggests recently that responsible parents should give their kids credit cards—possibly starting as young as middle school. The website says a credit card will help children master responsible spending habits and give parents the chance to teach them some valuable lessons.
It’s absolutely true that kids should learn about how a credit card works and how to use it responsibly. But the idea that they need a card of their own to practise this is questionable.
Yes, credit cards are a teaching tool, but it’s the time you spend educating them about money management that does the teaching, not the piece of plastic. Sit down with your child—here we are referring to teens and walk them through your credit card statements. Point out important things like the due date, late fee warning, and APR (年贷款利率).
If you have good credit, adding a child as an authorized user onto one of your credit cards also provides teachable moments. Allow kids to use the card to make specific purchases and require their participation in payment.
Since the card is still in your name, you can take them off it at any point and cut off their access if they're not able to handle the responsibility.
Another option is to set them up with an account at a local bank that offers free use of a debit card (借记卡). Unlike credit card, the debit card has no overdraft (透支) function.
Children can only use the card to pay for things and the money is taken directly from their bank account. If the account is empty, the worst that will happen is the card being declined at a cash register.
1.Why does Mint.com advise parents to give middle school kids credit cards?
A. To leave their kids financially independent.
B. To help their kids form good spending habits.
C. To teach their kids' how to save pocket money.
D. To strengthen the relationship with their kids.
2.The author considers a credit card as a teaching tool because ______.
A. it motivates teens to ask their parents for less financial support
B. it helps teenagers to know some basic knowledge of credit cards
C. it contains detailed financial information on the card surface
D. it offers parents the chance to teach kids to manage money
3.What is the purpose of adding kids as credit card authorized users?
A. To avoid extremely high overdraft fees.
B. To encourage them to share household expenses.
C. To teach them to be responsible credit card users.
D. To help them pay close attention to their bank account.
4.What is most likely to be discussed in the paragraph that follows?
A. Further information about the debit card.
B. The overdraft functions of a debit card.
C. More disadvantages of credit cards.
D. The kids' attitude towards a credit card.

Recently a study, led by Pedro Hallal of the Federal University, suggests that nearly a third of adults, 31%, are not getting enough exercise. That rates of exercise have declined is hardly a new discovery. Since the beginning of the industrial revolution, technology and economic growth have helped to create a world in which taking exercise is more and more an option rather than a necessity. But only recently have enough good data been collected from enough places to carry out the sort of analysis Dr Hallal and his colleagues have engaged in.
There are common themes in different places. Unsurprisingly, people in rich countries are less active than those in poor ones, and old people are less active than young ones. Less obviously, women tend to exercise less than men—34% are inactive, compared with 28% of men. But there are exceptions. The women of Croatia, Finland, Iraq and Luxembourg, for example, move more than their male countrymen.
Malta wins the race for most slothful country, with 72% of adults getting too little exercise, and Swaziland and Saudi Arabia are in close behind, with 69%. In Bangladesh, just 5% of adults fail to exercise enough. Surprisingly, six Americans in ten are active enough according to Dr Hallal’s study, compared with fewer than four in ten British.
These high rates of inactivity are worrying. Human beings seem to have evolved(进化) to benefit from exercise while deliberately avoiding it whenever they can. In a state of nature it would be impossible to live a life that did not provide enough of it. But that is no longer the case. Actually lack of enough activity these days has nearly the same effect on life span(寿命) as smoking.
1.We may learn from Paragraph 1 that_________.
A. the decline of exercise rates is newly discovered
B. the study suggests 31% of female adults get too little exercise
C. the good enough data has been collected from only one country
D. the industrial revolution has changed the way people live to some degree
2.According to the study, women of Luxembourg_________.
A. have little time to exercise
B. hate to get regular exercise
C. take more exercise to lose weight
D. exercise more than men in their country
3.The underlined word “slothful” in Paragraph 3 most probably means_________.
A. powerful B. rich C. lazy D. unpopular
4.What can be the best title for the text?
A. Worldwide Lack of Enough Exercise
B. New Health Discovery
C. Evolvement of Human Beings
D. Benefits of Taking Exercise
