WELLINGTON, September 19 (Xinhua) -- If your teenage son won't get out of bed in the morning, then take comfort from the fact that he might be sleeping his way to a healthier future, according to a new research from New Zealand.
Researchers in human nutrition at the University of Otago have found that teenage boys who sleep less have more body fat when compared to girls, for whom lack of sleep has no noticeable effect on their body fat ratios.
The study of 386 boys and 299 girls aged 15 to 18 found that average-sized 16-year-old boy weighing 69.5 kg and 176 cm tall, who slept for eight hours a day, had a waist size l.8 cm bigger and l.6 kg, or 9 percent, more body fat than the average-sized boy who slept 10 hours a day.
"The boys who slept eight hours a day would also have l.8 kg more lean (bone and muscle) mass compared to the boys who slept 10 hours, but that's only a 1.4-percent increase, compared to the 9- percent increase seen in body fat," said lead researcher from the Department of Human Nutrition, Dr. Paula Skidmore.
"Our results suggest that for older teenage boys, making sure that they get enough sleep may help to maintain a healthier body. It seems to be that, within reason, the more sleep the better for boys," Skidmore said in a statement Thursday.
"It was unexpected that we did not find the same result in girls, who may actually be more aware of their diet and more in tune with a healthier lifestyle."
The researchers ruled out the effects of food choice and number of screens, such as televisions, games and consoles, which the teenagers had in their bedrooms.

Another thing an astronaut has to learn about is eating in space．Food is weightless, just as men are．
Food for space has to be packed in special ways．Some of it goes into tubes that a man can squeeze into his mouth．Bite-sized cookies are packed in plastic．
There is a good reason for covering each bite．The plastic keeps pieces of food from traveling in the spaceship．On the earth very small pieces of food would simply fall to the floor．But gravity doesn’t pull them to the floor when they are out of the plastic in a spaceship．They move here and there and can get into a man’s eyes or into the spaceship’s instruments． If any of the instruments is blocked, the astronauts may have trouble getting safely home．
As astronauts travel on longer space trips, they must take time to sleep． An astronaut can fit himself to his seat with a kind of seat belt. Or, if he wants to, he can sleep in a sleeping bag which is fixed in place under his seat．But be careful he must put his hands under the belt when he goes to sleep．This is because he is really afraid that he might touch one of controls that isn’t supposed to be touched until later．
【小题1】Why would astronauts cover each bite of food in space？____
| A．Because small pieces of food would fall down to the floor． |
| B．Because weightless pieces of food might make trouble when they travel around． |
| C．Because they haven’t enough food for longer trips． |
| D．Because astronauts don’t want to waste food． |
| A．walk just as they do on the earth． |
| B．not eat anything because it’s dangerous． |
| C．control the spaceship when they are sleeping． |
| D．not litter small things or it will make trouble． |
| A．Because he thinks it is comfortable to sleep in that way in space． |
| B．Because he doesn’t want to touch any controls when he sleeps． |
| C．Because the instruments of the spaceship are easily broken． |
| D．Because he is afraid that the seat will move． |
| A．Eating and Sleeping in Space |
| B．How Astronauts Eat in Space |
| C．Food for Space |
| D．How Astronauts Sleep in Space |

There is no doubt that Apple is well aware of the increased competition in the market and could be in a hurry to put another product out there, said Ramon Llamas, senior research analyst at IDC Mobile Devices Technology and Trends. Given its history with product launches and business policy, though, Apple probably isn’t going to rush an iPhone release simply to put it on shelves, he said.
“If you’re Tim Cook (CEO of Apple), you’re thinking if you want to pay more attention to how to keep growing that bottom line and keep investors(投资人) happy, or continue with the same approach from Apple, which is do what we can do and manage products and releases in the best way they can work for us. Apple usually does things in their own time, and I’m having a hard time buying this May or June timeline.” Llamas told Mac News World.
While it’s probable that Apple is surely in a testing stage for its next smartphone, consumers likely have a standard wait for the finished product, said Colin Gibbs, analyst at GigaOm Pro.
“It typically takes a year or longer to create a state-of-the-art smartphone, so no one should be surprised Apple is in the testing stages with the next iPhone. And while it’s possible that Apple could launch the next iPhone this spring or summer, I’m not expecting to see it until a little later in the year,” he told Mac News World.
When it does launch, though, it could be in a variety of colors, said Gibbs. “Apple has already tested the waters with releasing colored products when it revamped (更新，翻新）its iPod line last fall, so it is understood that it would want the new change with its smartphone, as well”.
“I wouldn’t be surprised if the new iPhone becomes available in some new colors,’’ he said. “That could be done pretty cheaply, and it would give Apple a new marketing angle.”
【小题1】According to Ramon Llamas, Apple always ______.
| A．tries to please its investors |
| B．rushes to put new products to market |
| C．ignores the fierce market competition |
| D．does things as planned |
| A．the stage of its being tested |
| B．the rough time of its being released |
| C．the function to be improved |
| D．the wide variety of its color |
| A．Disapproving. | B．Indifferent (漠不关心的). | C．Doubtful. | D．Objective. |
| A．stories | B．comments | C．advertisements | D．debates |

Researchers found that people become happier and experience less worry after they reach the age of fifty. In fact, they say by the age of eighty-five, people are happier with their life than they were when they were eighteen years old.
The findings came from a survey of more than three hundred forty thousand adults in the United States. The Gallup Organization questioned them by telephone in two thousand eight. At that time, the people were between the ages of eighteen and eighty-five.
The researchers asked questions about emotions like happiness, sadness and worry. They also asked about mental or emotional stress.
Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of twenty-two and twenty-five.
The findings showed that stress levels dropped sharply after people reached their fifties.
Happiness was highest among the youngest adults and those in their early seventies. The people least likely to report feeling negative emotions were those in their seventies and eighties.
The findings appeared in the Proceedings of the National Academy of Sciences.
Researchers say they do not know why happiness increases as people get older. One theory is that, as people grow older, they grow more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.
Professor Stone says the emotional patterns could be linked to changes in how people see the world, or maybe even changes in brain chemistry.
The researchers also considered possible influences like having young children, being unemployed or being single. But they found that influences like these did not affect the levels of happiness and well-being related to age.
The study also showed that men and women have similar emotional patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men.
【小题1】What is the best title of the passage?
| A．The older a person is, the happier he grows. |
| B．The more lighthearted a person is, the happier he is. |
| C．The older a person is, the more clever he grows. |
| D．The older a person is, the more stressed he feels. |
| A．only when people get older, will they feel happier |
| B．older people usually have no worries in their life |
| C．older people are more likely to be thankful in life |
| D．stress levels among the youngest are the highest of all |
| A．When people get older, they can’t remember bad experiences. |
| B．When people get older, they have no young children to care about. |
| C．When people get older, they don’t care about their feelings. |
| D．When people get older, they learn to adjust their feelings. |
| A．Advice to the young people on how to keep happy. |
| B．Why women at all ages are more sad, stressed and worried. |
| C．Advice to the old people on how to live longer. |
| D．Why people will grow happier with their ages. |

Today is National Bike-to-Work Day. And on New York City’s jammed streets, people are cycling on hundreds of miles of new bike lanes. But New York’s widespread efforts to make streets safer for bikes have also left some locals complaining about the loss of parking spots and lanes for cars.
When the weather is good, Aaron Naparstek likes to pedal（用踏板踩）his two young kids to school on a special Dutch-made bicycle. Naparstek supports the new lane.
Aaron: The bike lane on Prospect Park West is really introducing a lot of new people to the idea that it’s possible to use a bike in New York City for transportation or to travel around. This is what 21st century New York City looks like.
Prospect Park West is still a one-way road, but where it used to have three lanes of car traffic, now it has two, plus a protected bike lane. Supporters say that makes the road safer for everyone, including pedestrians, by slowing down cars and taking bikes off the sidewalk. But some longtime residents disagree. Lois Carswell is president of a group called Seniors for Safety. She says the two-way bike lane is dangerous to older residents who are used to one-way traffic.
Lois: We wanted a lane — the right kind of lane that would keep everybody safe, that would keep the bikers safe. But we want it to be done the right way. And it has not been done the right way.
Craig Palmer builds bars and restaurants in Manhattan. I was interviewing him for a different story when he brought up the bike lanes all on his own.
Craig: I think the biggest problem is that Bloomberg put all these bike lanes in. You took what used to be a full street and you’re shrinking it.
Then there are the Hasidic Jews in Williamsburg, Brooklyn, who forced the city to remove a bike lane through their neighborhood. But polls show that the majority of New Yorkers support bike lanes by a margin of 56% to 39%. Bicycle advocate Caroline Samponaro of Transportation Alternatives calls that a mandate.
Caroline: If this was an election, we would have already had our victory. The public has spoken and they keep speaking. And I think, more importantly, the public is starting to vote with their pedals.
【小题1】What does Aaron mean by saying “This is what 21st century New York City looks like.”?
| A．There are hundreds of miles of new bike lanes in 21 st century New York City. |
| B．Drivers slow down their cars and bikes are taken off the sidewalk in New York. |
| C．Bikes are used as a means of transport in 21 st century New York City. |
| D．It’s possible to make the streets safe for pedestrians in New York. |
| A．Drivers lose parking spots and lanes for cars. |
| B．The two-way bike lane is dangerous to older residents. |
| C．We took what used to be a full street so the road is broader than before. |
| D．The removal of one bike lane through a neighbourhood in Brooklyn was not supported by the majority of New Yorkers. |
| A．the authority | B．the public | C．the supporters | D．the government |
| A．Ride on National Bike-to-Work Day |
| B．A New Bike Lane Appears in New York |
| C．A Bike Lane Divides New Yorkers |
| D．Who Wins an Election |

Fear may be felt in the heart as well as in the head, according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.
Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting (收缩) and pumping blood around their bodies, compared with the point when the heartbeat is relaxed. Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful event, depending on which point it is at in its regular cycle of contraction and relaxation.
Sarah Garfinkel at the Brighton and Sussex Medical School said: "Our study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart."
The study tested 20 healthy volunteers on their reactions（反应）to fear as they were shown pictures of fearful faces. Dr Garfinkel said, "The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed. Thus our hearts can also affect what we see and what we don't see - and guide whether we see fear."
To further understand this relationship, the scientists also used a brain scanner (扫描仪) to show how the brain influences the way the heart changes a person's feeling of fear.
"We have found an important mechanism by which the heart and brain ‘speak’ to each other to change our feelings and reduce fear," Dr Garfinkel said.
"We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced, we may be able to develop more successful treatments for anxiety disorders, and also for those who may be suffering from serious stress disorder."
【小题1】What is the finding of the study?
| A．One's heart affects how he feels fear. |
| B．Fear is a result of one's relaxed heartbeat. |
| C．Fear has something to do with one's health. |
| D．One’s fast heartbeats are likely to cause fear. |
| A．volunteers' heartbeats when they saw terrible pictures |
| B．the time volunteers saw fearful pictures and their health conditions |
| C．volunteers' reactions to horrible pictures and data from their brain scans |
| D．different pictures shown to volunteers and their heart-brain communication |
| A．Order. | B．System. | C．Machine. | D．Treatment. |
| A．treating anxiety and stress better |
| B．explaining the cycle of fear and anxiety |
| C．finding the key to the heart-brain communication |
| D．understanding different fears in our hearts and heads |

Sooner or later, many families will face the situation of moving. The experience can be very bad for kids, who may not be a part of the decision to move and may not understand it. You can take steps to make the entire process (过程) easier for everyone.
Many kids like to stay in familiar places. So as you consider a move, weigh the benefits (好处) of that change against the comfort that neighborhood, school, and social life give your kids. If your family has recently dealt with a big life change, such as death, you may want to put off a move to give your children time to accept the fact.
The decision to move may be out of your hands, perhaps because of a new job or money problems. Even if you’re not happy about the move, try to keep a positive (积极的)attitude to it. During the move, a parent’s attitude can greatly influence kids.
No matter what the results are, the most important way to prepare kids to move is to talk about it. Try to give your children as much information about the move as possible. You can ask kids to join in the planning such as house-hunting or the search for a new school. This can make the change feel less like it’s being forced on them. If you’re moving across town, try to take your children to visit the new house and the new neighborhood.
A move can have many problems, but good things also come from this kind of change. Your family might grow closer and you may learn more about each other by going through it together.
【小题1】According to the text, a move can be a bad experience for kids because ______.
| A．they may feel they’re forced to do so |
| B．they often feel lonely in a new school |
| C．they are ignored by their busy parents |
| D．they are tired of the moving process |
| A．Allowing them to choose a school by themselves. |
| B．Trying not to show them the bad parts of a move. |
| C．Offering them as much information as possible. |
| D．Promising to choose a new house with them. |
| A．what we should do before a move |
| B．how to prepare children for a move |

“Get your hands off me, I have been stolen,” the laptop, a portable（便携式的）computer, shouted. That is a new solution to laptop computer theft: a program that lets owners give their property a voice when it has been taken.
The program allows users to display alerts（警报）on the missing computer’s screen and even to set a spoken message. Tracking software for stolen laptops has been on the market for some time, but this is thought to be the first that allows owners to give the thief a piece of their mind.
Owners must report their laptop missing by visiting to a website, which sends a message to the model: a red and yellow “lost or stolen” sign appears on its screen when it is started. Under the latest version(版本) of the software, users can also send a spoken message.
The message can be set to reappear every 30 seconds, no matter how many times the thief closes it. “One customer sent a message saying, ‘You are being tracked. I am right at your door’,” said Carrie Hafeman, chief executive (主管) of the company which produces the program, Retriever.
In the latest version, people can add a spoken message. For example, the laptop’s speakers will say: “Help, this laptop is reported lost or stolen. If you are not my owner, please report me now.”
The Retriever software package(软件包), which costs $29.95 (￡21) but has a free trial period, has the functions of many security software programs. Owners can remotely switch to an alternative password if they fear that the thief has also got hold of the access details.
If a thief accesses the internet with the stolen laptop, Retriever will collect information on the internet service provider in use, so that the police can be alerted to its location.
Thousands of laptops are stolen every year from homes and offices, but with the use of laptops increasing, the number stolen while their owners are out and about has been rising sharply.
Other security software allows users to erase（删除）data remotely or lock down the computer.
【小题1】The expression “to give the thief a piece of their mind” can be understood as “_______”.
| A．to give the thief an alert mind |
| B．to express the owners’ anger to the thief |
| C．to remind the thief of his conscience |
| D．to make the thief give up his mind |
| A．record the stealing process |
| B．help recognize the lost laptop |
| C．lock down the computer remotely |
| D．send a spoken message |
| A．change some access details for switching on the laptop |
| B．turn on the laptop by using the original password |
| C．operate the laptop by means of an alternative password |
| D．erase the information kept in the stolen laptop |
| A．With no Retriever, thousands of laptops are stolen every year. |
| B．A new software provides a means to reduce laptop theft. |
| C．Retriever has helped to find thieves and lost computers. |
| D．A new program offers a communication platform with the thief. |
