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.

举一反三
Keeping that in mind, I"d just like to consider conditions elsewhere in the known universe. You really only need to look at our own solar system or the Earth at certain periods in its own history to appreciate that most places are much worse and much less suitable for life than our mild, watery globe.
So far, space scientists have discovered about seventy planets outside the solar. But it appears that if you wish to have a planet suitable for life, you just have to be very lucky, and the more advanced the life is, the luckier you"ll have to be. I"m by no means a space observer, but I can recognize some particularly fortunate breaks we"ve had on the Earth. For example:
We are, to a degree, at the right distance from the perfect type of star, the one that is big enough to radiate a huge amount of energy, but not so big as to bum itself out quickly. Had our sun been ten times as huge, it would have burnt out completely after only ten million years, instead of ten billion and surely we would not exist. Too near, everything on the Earth would have boiled and withered away; any further, everything would have frozen over.
The universe is a surprising place, and our existence within it is a wonder. If a long and unimaginably complex sequence of events dating back 4.6 billion years or so hadn"t happened in a particular manner at a particular time --if, to take just one example, the dinosaurs hadn"t been wiped out by a meteor(流星)--we might still be a few centimeters long, with whisker(胡须) and a tail, and you"ll be reading this in a cave somewhere.
小题1:What"s the best title for this passage?
| A．No Life Exists out of the Earth |
| B．Seventy Planets Discovered |
| C．A Place Full of Wonders |
| D．Perfect Conditions for Life |
| A．The Earth is the only planet that can receive energy from the sun. |
| B．The sun is at the right distance from us and in proper size. |
| C．The distance between the planets was neither too long nor too near. |
| D．The dinosaurs were no longer a threat to the Earth. |
| A．Exploded. | B．Expanded. | C．Floated away. | D．Dried and died. |
| A．A history book. | B．A magazine. | C．A science fiction. | D．A famous novel. |
Despite organized anti-bottled-water campaigns across the country and a noisy debate about bottled water’s environmental impact, Americans are buying more bottled water than ever.
Why do so many people seem to think they should have any input on what other American’s choose to buy or do?
If they want to buy bottled water, let them.
If they want to eat fast food, let them.
If they want to smoke pot, let them.
— Barackalypse
People just get tired of paying for others’ bad behavior. If many people eat excessive fast food, you pay higher insurance premiums. If many people frequently buy bottled water, your trash bills go up and landfills fill up quickly.
It’s about personal responsibility, which really should be a cornerstone of libertarianism.
— Bdbr
So? This is the price you pay to live in a free society. You want to control the life of another just so you can save a few bucks? What would you say when someone do the same to you?
— Norman619
Defend selfish pricks all you like; I’m just glad there are still people who still believe personal responsibility is a good and decent thing. We make your life cheaper and less bothersome.
— Yoyo
What a waste of money! It’s fine when you’re on the road and you need a cold drink, but people who buy cases of bottled water for home are completely crazy.
— Agmlauncher
I wish we all can find a way to improve things and benefit from this. The environment needs a lot of help but businesses will always work on what people would need and demand. Is this part of the balance? Hope we can find better ways.
— Skipweis

They can not only give you a lot of information about American culture, but also offer some useful daily expressions. Watching them will help you enlarge your vocabulary and teach you correct language usage in different situations. Best of all, situation comedies are a fun way to learn.
The Apprentice
The American reality (现实) TV show is hosted by the famous businessman Donald Trump. It’s based on the idea of the final job interview for the final job. The show picks 16 people to compete for a job with Trump’s business. Those who fail their weekly tasks have to meet with Trump. They have to explain why they should not be fired (解雇).
The Apprentice is useful for English students who want to learn how to make up a persuasive (令人信服的) argument. For example, rather than say “I think I did a good job”, one may also learn to throw off the possibility of uncertainty by saying, “I did a good job.”
Desperate Housewives (DH)
Desperate Housewives is set in an invented American town, Wisteria Lane. It follows a group of middle-aged women as they go through their daily family lives. But in fact, those women live a life of lies, secrets, criminal (犯罪的) acts, and mystery.
This program is good at expressing the funny life of American neighbors. And, it’s the perfect comedy series for foreign learners wanting to see how to hold a relaxed daily conversation.
Another reason for watching DH is to learn some expressions American families use that are not in your English language textbooks. For example, the mothers often use words such as “sport” and “you guys” to speak about their kids.
小题1:According to the passage, The Apprentice and DH are introduced because _____.
| A．they are now the most popular programs |
| B．they are helpful in English learning |
| C．they are advertised for English beginners |
| D．they are enjoyed by most young people |
| A．communicate with native speakers |
| B．know about American culture |
| C．pick up English daily expressions |
| D．learn more English words |
| A．common | B．difficult | C．enjoyable | D．possible |
| A．tells a story of school life | B．is about real life |
| C．has 15 actors | D．is about some businessmen |
| A．The story happens in a village of America. |
| B．The housewives join in the same job interview. |
| C．The women in the American town lead a life full of sadness. |
| D．It does well in describing an interesting neighborhood in America. |
Since June 2008 China has forbidden the production, sale and usage of plastic bags thinner than 0.025 millimeter (毫米), and retailers (零售商) are not allowed to provide free plastic bags to their customers, no matter how thick they are.
Many Chinese consumers like Jiang have learned to refuse plastic bags whenever possible in their shopping. "A plastic bag may only cost a few jiao, but it"s more about how bad they are for the environment," Jiang said.
The plastic ban is for the most part well carried out in big cities, and has been obviously effective in reducing white waste. On the first anniversary of the plastic ban Global Village of Beijing, an NGO environmental organization, shows that during the year of the ban the consumption of plastic bags fell by about 40 billion pieces in chain supermarkets alone, saving more than 1.2 million tons of petrol.
However, enforcement (实施) shows rather less muscle in smaller cities, towns and countryside. In a remote town like Lichuan, the awareness of environmental protection is not as strong as that in big cities. Street vendors (街头小贩) worry that they are likely to lose customers if they charge them for plastic bags. Seeing no significance in the issue, local government often turn a blind eye to banned bag trade in the market.
There are still those who don"t have an interest in living green. Cui Lin, another Beijinger, often forgets to bring a cloth bag when shopping, and has to buy plastic bags. "Anyway I think plastic bags are neater and cleaner, and I don"t mind paying a couple more jiao," he shrugged.
Mrs Yu, a vegetable vendor in Lichuan County, Jiangxi Province, recalled that before plastic bags became popular in the early 1990s, Chinese people always carried a bamboo basket when they visited the market. "Plastic bags are more convenient," she comments, and her view might be that of the tens of millions of people in the nation who still cling to plastic bags, paid or free. This is suggested by her trade where piles of plastic bags are still passed out every day.
小题1: In Paragraph 1, the writer uses Jiang Nan"s case to __________.
| A．introduce a topic | B．tell a story |
| C．describe a person | D．offer an argument |
| A．She bought them at a low price. |
| B．She borrowed them from her relatives. |
| C．She got them for free. |
| D．She made them herself. |
| A．Cloth bags are difficult to get and heavy to carry. |
| B．People"s awareness of environmental protection is not strong enough. |
| C．People don"t mind paying a couple more jiao for plastic bags. |
| D．Street vendors worry that they are likely to lose customers if they charge them. |
| A．stop using | B．continue to use | C．stay close to | D．hold tightly |
| A．To reduce white waste is urgent. |
| B．The plastic bag ban has achieved great success. |
| C．There is still a long way to go for the plastic bag ban. |
| D．People"s awareness of environmental protection should be stressed. |
Peter Butler from London’s Royal Free Hospital called for a debate on the ethics of such an operation made possible by new drugs which stop the body’s immune (免疫）system rejecting a transplanted face. “It is not ‘can you do it?’ but ‘should we do it?’” he told the BBC. “The technical part is not complex, but I don’t think that’s going to be the very great difficulty. The ethical and moral debate is obviously going to have to take place before the first facial transplantation.”
The British Association of Plastic Surgeons will discuss the microsurgical procedure (微型外科技术), which could give new skin, bone, nose, chin, lips and ears from deceased donors to patients disfigured（毁容的）by accidents, burns or cancer. But surgeons could have trouble finding enough willing donors. Butler said his survey of doctors, nurses and members of the public showed most would accept a face transplant but few were willing to donate their own after dying.
Despite a number of ethical concerns, Christine Piff, who founded the charity Let’s Face It after suffering a rare facial cancer 25 years ago, welcomed the possibility of face transplants. She rejected the idea that the procedure would mean people would end up living with a dead person’s face. “There are so many people without faces, I have half a face… but we are all so much more than just a face… you don’t take on their personality. You are still you,” she told reporters. “If we can donate other organs of the body then why not the face. I can’t see anything wrong with it.”
小题1:The underlined word “deceased” in the third paragraph probably means _________.
| A．living | B．dead | C．diseased | D．dying |
| A．who are dishonorable and shameless |
| B．who disagree with the full face transplant |
| C．who are seriously injured by an accident |
| D．who are disfigured by accidents, burns and cancer |
| A．Drugs are available to stop the body’s immune system rejecting a transplanted face. |
| B．There are some people who are willing to donate their faces after dying. |
| C．Most people accept the idea of face transplants. |
| D．It’s morally practical, though technically complex. |
| A．Christine Piff has been the first lucky patient to receive a face transplant. |
| B．Surgeons have difficulty finding enough willing donors. |
| C．The main difficulty with the operation lies in the matter of ethics and morality. |
| D．Nobody other than Christine Piff is quite in favor of the donation of organs. |
| A．First Facial Transplantation |
| B．Debate on the Ethics of Transplant |
| C．Face Transplant No Longer Science Fantasy |
| D．Let’s Face It |
