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.

For a while, my neighborhood was taken over by an army of joggers (慢跑者). They were there all the time: early morning, noon, and evening. There were little old ladies in gray sweats, young couples in Adidas shoes, middle-aged men with red faces. "Come on!" My friend Alex encouraged me to join him as he jogged by my house every evening. "You'll feel great."
Well, I had nothing against feeling great and if Alex could jog every day, anyone could. So I took up jogging seriously and gave it a good two months of my life, and not a day more. Based on my experience, jogging is the most overvalued form of exercise around, and judging from the number of the people who left our neighborhood jogging army. I'm not alone in my opinion.
First of all, jogging is very hard on the body. Your legs and feet have a real pounding (追击) ruining down a road for two or three miles. I developed foot, leg, and back problems. Then I read about a nationally famous jogger who died of a heart attack while jogging, and I had something else to worry about. Jogging doesn't kill hundreds of people, but if you have any physical weaknesses, jogging will surely bring them out, as they did with me.
Secondly, I got no enjoyment out of jogging. Putting one foot in front of the other for forty-five minutes isn't my idea of fun. Jogging is also a lonely pastime. Some joggers say, "I love being out there with just my thoughts" Well, my thoughts began to bore me, and most of them were on how much my legs hurt.
And how could I enjoy something that brought me pain? And that wasn't just the first week: it was practically every day for two months. I never got past the pain level, and pain isn't fun. What a cruel way to do it! So many other exercises, including walking, lead to almost the same results painlessly, so why jog?
I don't jog any more, and I don't think I ever will. I'm walking two miles three times a week at a fast pace, and that feels good. I bicycle to work when the weather is good. I'm getting exercise, and I'm enjoying it at the same time. I could never say the same for jogging, and I've found a lot of better ways to stay in shape.
【小题1】From the first paragraph, we learn that in the writer's neighborhood _____.
| A．people jogged only during the daytime |
| B．jogging became very popular |
| C．Alex organized an army of joggers |
| D．jogging provided a chance to get together |

When you think of the tremendous technological progress we have made, it’s amazing how little we have developed in other respects. We may speak contemptuously of the poor old Romans because they relished the orgies of slaughter that went on in their arenas. We may despise them because they mistook these goings on for entertainment. We may forgive them condescendingly because they lived 2000 years ago and obviously knew no better. But are our feelings of superiority really justified? Are we any less blood-thirsty? Why do boxing matches, for instance, attract such universal interest? Don’t the spectators who attend them hope they will see some violence? Human beings remains as bloodthirsty as ever they were. The only difference between ourselves and the Romans is that while they were honest enough to admit that they enjoyed watching hungey lions tearing people apart and eating them alive, we find all sorts of sophisticated arguments to defend sports which should have been banned long age; sports which are quite as barbarous as, say, public hangings or bearbaiting.
It really is incredible that in this day and age we should still allow hunting or bull-fighting, that we should be prepared to sit back and watch two men batter each other to pulp in a boxing ring, that we should be relatively unmoved by the sight of one or a number of racing cars crashing and bursting into flames. Let us not deceive ourselves. Any talk of ‘the sporting spirit’ is sheer hypocrisy. People take part in violent sports because of the high rewards they bring. Spectators are willing to pay vast sums of money to see violence. A world heavyweight championship match, for instance, is front page news. Millions of people are disappointed if a big fight is over in two rounds instead of fifteen. They feel disappointment because they have been deprived of the exquisite pleasure of witnessing prolonged torture and violence.
Why should we ban violent sports if people enjoy them so much? You may well ask. The answer is simple: they are uncivilized. For centuries man has been trying to improve himself spiritually and emotionally – admittedly with little success. But at least we no longer tolerate the sight madmen cooped up in cages, or public floggings of any of the countless other barbaric practices which were common in the past. Prisons are no longer the grim forbidding places they used to be. Social welfare systems are in operation in many parts of the world. Big efforts are being made to distribute wealth fairly. These changes have come about not because human beings have suddenly and unaccountably improved, but because positive steps were taken to change the law. The law is the biggest instrument of social change that we have and it may exert great civilizing influence. If we banned dangerous and violent sports, we would be moving one step further to improving mankind. We would recognize that violence is degrading and unworthy of human beings.
【小题1】It can be inferred from the passage that the author’s opinion of nowadays’ human beings is
| A．not very high. | B．high. |
| C．contemptuous. | D．critical. |
| A．vicious and dangerous sports should be banned by law. |
| B．people are willing to pay vast sums money to see violence. |
| C．to compare two different attitudes towards dangerous sports. |
| D．people are bloodthirsty in sports. |
| A．To compare the old Romans with today’s people. |
| B．to give an example. |
| C．to show human beings in the past know nothing better. |
| D．to indicate human beings are used to bloodthirsty. |
| A．Three. | B．Five. |
| C．Six. | D．Seven. |
| A．that, by banning the violent sports, we human beings can improve our selves. |
| B．that, by banning the dangerous sports, we can improve the law. |
| C．that we must take positive steps to improve social welfare system. |
| D．to show law is the main instrument of social change. |

Most children, even the youngest of children, are delighted to be around cats and dogs. But these pets carry plenty of germs and allergens（过敏原）, prompting researchers to ask: Are cats and dogs really safe for children？
A study finds that, contrary to many parents’ fears, owning cats or dogs does not increase a child’s risk of developing allergies, and in fact, may actually protect them. The study’s lead author, Dr. Dennic Ownby of the Medical College of Georgia, says that even he was “very surprised” by the results. Ownby and colleagues followed more than 470 children from birth to age 6 or 7, comparing those exposed to cats and dogs during their first year of life to those who were not.
By using skin-prick tests for detecting common allergies, the researchers found that, contrary to what many doctors had been taught for years, children who had lived with a pet were not at greater risk.
Even more remarkable, children who had two or more dogs or cats had an even greater reduction, up to 77 percent, in risk of allergies. Researchers suggest this protective effect may be the result of early exposure to lots of bacteria that are carried by dogs and cats. Exposing young children to these bacteria helps "exercise" their immune systems early in life so that they're better able to resist allergic diseases later.
There's something very important in that first year of life when the immune(免疫) system is developing that we can retrain it away from an allergic response, said Dr. William Davis.
And while researchers are not encouraging parents to buy dogs or cats just to reduce a child’s allergy risk, they say if a family already has one or more animals, there's no need to get rid of them.
【小题1】Why do the researchers feel “very surprised” by the results of the study?
| A．Because the results are contrary to their expectation． |
| B．Because so many children are playing with cats and dogs． |
| C．Because parents are so much worried about their children． |
| D．Because children with animals may develop allergies easily． |
| A．will lose the chance to develop immune system |
| B．will reduce the harm from bacteria |
| C．may suffer allergic diseases more often |
| D．can keep doctors away |
| A．the early life | B．an allergic disease |
| C．something important | D．immune system |
| A．How to protect your kids from allergies |
| B．Bacteria do good to your kids |
| C．Your pets may be helping your kids |
| D．Advantages of owning pets |

People born in winter are more likely to suffer mental health disorders, according to a recent study carried out by researchers at Vanderbilt University in Tennessee.
Researchers raised baby mice from birth to weaning (断奶) in either “summer” light cycles of 16 hours of light and 8 hours of dark or “winter” cycles of 8 hours of light and 16 hours of dark. A third group experienced 12 hours of light and 12 hours of dark a day.
Then half the winter mice stayed in a winter cycle, while half switched to a summer schedule. The summer mice were similarly split. The mice raised in equal periods of light and dark were split into three groups, one of which stayed on the 12hour schedule, one of which joined the winter group, and one of which joined the summer group.
After 28 days, it turns out the summerborn mice behaved the same whether they stayed on the summer cycle or switched to winter. But among the winterborn mice, those stayed in winter kept their previous schedule, while those that switched to summer stayed active for an extra hour and a half, which indicates that mice born and weaned in a winter light cycle showed dramatic disruptions in their biological clocks.
The finding is the first of its kind in mammals, and it could explain why people born in winter are at higher risk for mental health disorders including bipolar depression, schizophrenia and seasonal affective disorder.
“We know that the biological clock regulates mood in humans，”said study researcher McMahon. “If the mechanism (机制) similar to the one that we found in mice operates in humans, then it could not only have an effect on a number of behavioral disorders, but also have a more general effect on personality.”
【小题1】How many groups of mice are there finally in all in the experiment?
| A．Four. | B．Five. | C．Six. | D．Seven. |
| A．The biological clock regulates mood in humans. |
| B．People born in winter are at higher risk for physical health disorders. |
| C．Being born in winter has a negative effect on people's mental health. |
| D．The length of light will influence the behavior of the mice. |
| A．ended | B．torn | C．hit | D．divided |
| A．A jobhunter. | B．A student in the university. |
| C．A newlymarried couple. | D．An experienced dentist. |

When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.
People who are near-sighted can only see things that are very close to their eyes. Everything else seems unclear. Many people who do a lot of work, such as writing, reading and sewing become near-sighted.
Then people who are far-sighted endure just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses, too.
Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism（散光）. This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts（白内障）. Long ago these people often became blind. Now however, it is possible to operate on the cataracts and remove then.
Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle（角度）. To prove this to yourself, look at an object out of one eye; then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.
【小题1】We should take good care of our eyes .
| A．only when we can see well |
| B．only when we cannot see perfectly |
| C．only when we are near-sighted or far-sighted |
| D．even if we can see well or perfectly |
| A．near-sighted | B．far-sighted | C．astigmatic | D．suffering from cataracts |
| A．experience | B．imagine | C．suffer from | D．recover from |
| A．seeing at night | B．seeing objects far away |
| C．looking over a wide area | D．judging distances |
| A．one eye bigger than the other |
| B．eyes that are not exactly the right shape |
| C．a difficulty that can be corrected by an operation |

Having one of those days or weeks when everything seems to annoy you? Even if you do nothing about it, your bad mood(心情) will probably go away after some time. But with a little effort, you can forget it much faster—often within a day or two.
Walk it off
Exercise is the most popular bad mood buster. A person who's in a bad mood has low energy and high tension. Taking a fast ten-minute walk, or doing some quick exercises can do wonders towards changing the bad mood.
Tune it out
Listening to your favorite music for a while can also make tension go away quickly, because music starts connection with past positive experiences we've had.
Give yourself a paper talk
Stop and listen to what's on your mind. Bad moods are often started by too many negative thoughts. Write them all down on paper, the pessimistic(悲观的) messages you've been giving yourself, and then give optimistic answers. (“I still don't have a job.” vs “I have two interviews next week.”)
Reduce your stress
Relaxation techniques are wonderful moodlifters. These include deep breathing, stretching and visualizing(想像), all of which sound complicated(复杂的) but aren't. One easy way to visualize: close your eyes and picture a favorite place, such as the beach. Another simple way to distress is to make a todo list. One reason for being in a bad mood is feeling you have no options. By taking control over certain areas, you realize you're not helpless. You can make changes in your mood and life.
Avoid things that won't improve your mood
TV may not help much: you need to increase your energy level and stimulate(刺激) your mind—something that the TV show “Neighbors” won't do. And before you reach for that piece of cake and coffee, think about how mood and food are linked. Sugar and caffeine contribute to depressed moods. The better choice? Research shows that carbohydrates, such as potatoes and pasta(面食), produce calming effects in people who have a desire for them.
【小题1】Which of the following may help us stop a bad mood?
| A．Doing nothing about it |
| B．Exercising and enjoying music. |
| C．Writing down negative thoughts |
| D．Talking about it with neighbors. |
| A．It helps remove bad mood. |
| B．It brings us a new technique. |
| C．It is not complicated to do so. |
| D．It is an area to be easily controlled. |
| A．shows what happens around you | B．does not energize you |
| C．reminds you of eating and drinking | D．produces a calming effect |
| A．Energy Level and Stress | B．How to Beat a Bad Mood |
| C．Bad Mood and Our Life | D．How to Control Your Feeling |

If you were on the street in Mexico today you might think you were in an operating room, surrounded by doctors. You could see many concerned people with masks (口罩) trying their best to stop the swine flu (猪流感). And the masks aren’t only being used in Mexico. A friend of mine traveling from New York City to Florida was given a mask and a pair of gloves just after he reached the airport. And another friend went to get a haircut only to be faced with a hairdresser wearing a mask!
But do the masks really work? Is covering your nose and mouth the key to stopping the swine flu? To find out the truth, ABC’s reporter Sharyn Alfonsi talked with germ (细菌) expert Dr. Elaine Larsen. It turns out that when you sneeze (打喷嚏) the air coming out of your mouth at a speed of one hundred miles per hour carries germs which can travel anywhere around you and make people around you infected (被感染).
However, whether you become infected actually depends on the weather. As Sharyn reported, when you sneeze, the germs leave your body in small drops of water coming out of your mouth. If the weather is wet, the wet air will make the small drops bigger and heavier and they drop down towards our feet. If this happens, we won’t become infected. But if the air is dry, those small drops can float higher up, making it possible for them to touch someone else’s nose, mouth or their mask.
Larsen says the masks can stop the germs well but after a few hours, they start to get wet, holding a lot of germs they come across and causing you to breathe them in. The masks do work, but the key to stopping the germs is changing your masks often.
【小题1】According to Para.1, in Mexico you can see that ____.
| A．the patients are treated in the open air |
| B．some doctors work in the street |
| C．people speak little to each other in the street |
| D．many people wear masks in the street |
| A．breathing | B．Speaking | C．touching others | D．sneezing |
| A．sick people will be infected |
| B．germs can spread very far |
| C．germs spread very quickly |
| D．few people will be infected |
| A．the mask will be old and worn out |
| B．you’ll love the feeling of wearing it |
| C．germs will be kept away from you |
| D．it will be easy for you to be infected |
| A．Keeping the masks dry. | B．Changing the masks often. |
| C．Choosing very thick masks. | D．Wearing big masks. |
