How often do you change your hairstyle or ask for new dresses? You may be 31 to follow trends（潮流）in Western countries, but young people in the United States don’t care as much about
32 as you do.
A recent survey(调查) among high school 33 in China, Japan, South Korea and the US found that 34 teenagers care more about their appearance than young people in the US.
This survey was held in 156 high schools in the four countries. More than 7,000 teenagers were
35 about their views on life and the world. South Koreans, at 83 per cent, cared most about their looks. They were 36 by the Chinese and Japanese, while US students showed the least interest in fashion at only 33 per cent.
“The different results show 37 of cultural background（背景）,” said Sun Yunxiao from the China Youth and Children Research Centre. He explained that in the US there are many different 38 of beauty, so teens are more 39 to be confident about their appearance.
US teenagers’ high self-confidence is displayed（展示） in the 40 . About 85 per cent are happy with themselves. The percentage of self-confident Chinese students stands at only 30 per cent.
What’s 41 , US students showed more individuality（个性）, with 88 per cent 42 that “people should follow their own interests rather than 43 of others”. This is much 44 than South Korea’s 69 per cent, China’s 49 and Japan’s 48.
Japanese students, at 52 per cent, are most dissatisfied with modern society. Chinese and Koreans follow at second and 45 most dissatisfied.
“ 46 to the survey, Chinese students are happy and disciplined (有纪律的). They have a strong wish to make a difference. 47 Chinese students need to be more independent and learn how to relax,” said Sun.
The students have different 48 backgrounds. But home and places where friends gather are the favorite places all teens seek happiness.
Exams and worries about life after graduation cause much 49 among most of the teens
50 for the survey.

At the beginning of this century, medical scientists made an interesting discovery; we are built not just of flesh and blood but also of time. They were 36 to show that we all have “a body clock” 37 us, which controls the 38 and fall of our body energies, 39 us different from one day one to the next.
The 40 of “a body clock” should not be too 41 since the lives of most living things are controlled 42 the 24 hour night-and-day cycle. We feel 43 and fall asleep at night and become 44 and energetic during the day. If the 24 hour-cycle is 45 , most people experience unpleasant 46 . For example, people who are not 47 to working at night can find that 48 of sleep causes them to 49 badly at work.
50 the daily cycle of sleeping and 51 , we also have other cycles which 52 longer than one day. Most of us would 53 that we feel good on some days and not so good on 54 ; sometimes our ideas seem to flow and at other times, they 55 do not exist.

Of all living creatures on earth, insects are the most plentiful. Some 1 are very useful to man, for example, bees, 2 we get honey and wax, and silkworms, which 3 us with silk. Other varieties, 4 , are extremely harmful, and do a great 5 of damage, especially to crops. Locusts are perhaps the most dangerous of all, 6 they will eat almost any green 7 , and when millions of them 8 on cultivated land they soon leave it 9 . In some countries they are the farmers’ 10 enemy. Another nuisance is the common 11 , not only because it 12 us indoors and out-of-doors, but because it spreads diseases.
Scientists have given much time and 13 to the study of insects. It needs the most careful and 14 observation.

Cutting meat production and consumption by 30 percent would help to reduce carbon emissions(排放) and improve health in the most meat-loving nations, scientists said on Wednesday.
Using prediction models, British and Australian researchers 1 that improving efficiency, increasing carbon capture and 2 fossil fuel dependence in farming would not be enough to 3 emissions targets.
But combining these steps 4 a 30 percent reduction in livestock（家畜） 5 in major meat-producing nations and a similar 6 in meat-eating, would lead to "substantial population health benefits" and cut emissions, they said.
The study found that in Britain, a 30 percent 7 intake of animal-source saturated（饱和的） fat by adults would reduce the 8 of premature（过早的） deaths from heart disease by some 17 percent -- equivalent to 18,000 premature deaths reduced in one year.
In Sao Paulo, Brazil, it could mean as 9 as 1,000 premature deaths reduced in a year, they said.
10 the United Nations Food and Agricultural Organization, 18 percent of all greenhouse gas emissions are from meat production and experts say rising 11 for meat, particularly in countries with growing economies, could 12 livestock production up by 85 percent from 2000 levels 13 2030.
The scientists said global action was needed to maximize the benefits of cutting meat production and 14 , and that the environmental 15 "may apply only in those countries that currently have high production levels."
The study was 16 in The Lancet medical journal as part of a series in climate change and health 17 the Copenhagen global climate summit scheduled next month.
In a second study, British scientists found that increased walking and cycling, and 18 cars, would have a much greater impact on health 19 low-emission vehicles in rich and middle-income countries.
Andrew Haines, director of the London School of Hygiene and Tropical Medicine and head of the research series, said delegates at Copenhagen needed "to understand the potential 20 impacts of their plans."

Once in a blue moon there is one on New Year's Eve. Revelers ringing in 2010 will be treated to a so-called blue moon. According to popular definition, a blue moon is the second full moon in a month. But don't 1 it to be blue - the name has nothing to 2 the color of our closest celestial（天体） neighbor.
A full moon 3 on December 2. It will appear again on Thursday in time for the New Year's countdown.
"If you're in Times Square, you'll see the 4 moon right above you. It's going to be that brilliant," said Jack Horkheimer, director emeritus of the Miami Space Transit Planetarium and host of a weekly astronomy TV show.
The New Year's Eve blue moon will be 5 in the United States, Canada, Europe, South America and Africa. For partygoers in Australia and Asia, the full moon does not show up 6 New Year's Day, making January a blue moon month for them.
However, the Eastern Hemisphere can celebrate with a partial lunar eclipse（月蚀） on New Year's Eve when 7 of the moon enters the Earth's shadow. The 8 will not be visible in the Americas.
A full moon occurs 9 29.5 days, and most years have 12. 10 , an extra full moon in a month - a blue moon - occurs every 2.5 years. The 11 time there was a lunar double take was in May 2007. New Year's Eve blue moons are rarer, occurring every 19 years. The last time was in 1990; the next one won't 12 again until 2028.
Blue moons have no astronomical 13 , said Greg Laughlin, an astronomer at the University of California, Santa Cruz.
"`Blue moon' is just a 14 in the same sense as a `hunter's moon' or a `harvest moon,'" Laughlin said in an e-mail.
The popular definition of blue moon 15 after a writer for Sky & Telescope magazine in 1946 misunderstood the Maine Farmer's Calendar and marked a blue moon as the second full moon in a month. In fact, the calendar 16 a blue moon as the third full moon in a season with four full moons, not the usual three.
Though Sky & Telescope corrected the 17 decades later, the definition caught on. For purists（语言纯正癖者）, however, this New Year's Eve full moon doesn't even qualify as a 18 moon. It's just the first full moon of the winter season.
In a tongue-in-cheek essay 19 on the magazine's Web site this week, senior contributing editor Kelly Beatty wrote: "If skies are clear when I'm 20 celebrating, I'll take a peek（眯着眼睛看） at that brilliant orb（天体） as it rises over the Boston skyline to see if it's an icy shade of blue. Or maybe I'll just howl."

For some people, the sight of a mouse can be reason to scream. For other mice, the same sight can be reason to sing.
Mice will probably 21 sing their way to any concert, but researchers in the United States have found 22 that mice do, 23 , sing.
Scientists already knew that mice make ultrasonic(超声波) sounds—noises that are too high-pitched(高音的) for people to hear 24 special equipment.
To find out whether mice put such sounds together in song-like 25 , the researchers recorded the sounds of 1 mice. Using computer 26 , they were able to separate the sounds into specific types of syllables(音节), and found the mice produced about 10 syllables per second.
The results showed that nearly all of the mice repeated sequences(顺序) of syllables in different patterns. That’s enough to meet the definition of what scientists 27 song. But not all scientists are 28 _ that what the mice are doing is 29 singing. To prove it, the researchers must show that there’s learning involved. And, they need to __ 30 why the mice sing.

Throughout history man has had to accept the fact that all living things must die. But people now live longer than they 36 . Yet, all living things still show the 37 of aging, which will eventually 38 death.
Aging is not a disease, but as a person passes maturity (成熟期), the cells of the body and the 39 they form do not function as well as they 40 in childhood and teenage years. The body provides less 41 against disease and is more 42 to have accident.
A number of related causes may 43 aging. Some cells of the body have a fairly long life, but they are not 44 when they die. As a person ages, 45 of brain cells and muscle cells decreases. 46 body cells die and are replaced by new cells. In an aging person the 47 cells may not be as workable or as capable 48 growth as those of a young person.
Another 49 in aging may be changes within the cells 50 . Some of the protein chemicals in cells are known 51 with age and become less elastic (有弹性的). This is why the skin of old people wrinkles (皱纹) and 52 . This is also the reason why old people 53 in height. There may be other more important chemical changes in the cells. Some complex cell chemicals, such as DNA and RNA, store and 54 information that the cells need． Aging may affect this 55 and change the information-carrying molecules so that they do not transmit the information as well.
