When doctors urge overweight kids to pick up more activities,reading probably isn't what they
have in mind．Yet a new study by fatness researchers at Duke University finds that the simple act
of reading-depending on the choice of material-can cause weight loss in teenage girls．
The study's experimental group included 31 fat girls aged 9 to 13,who took part in the Healthy
Lifestyles Program at Duke Children's Hospital．The girls read a novel called Lake Rescue,whose
protagonist (主人公) is an overweight teenager who struggles with low selfesteem,feelings of loneliness
and teasing because of her size．A group of 33 girls read a different book called Charlotte in Paris,
which did not have an overweight character,and another group of 17 girls read neither book．
At the end of the sixmonth experiment,all the girls who read books had lost weight,but the girls who
read Lake Rescue lost more．They lowered their bo
dy mass index (BMI) by 0.71,compared with
0.33 in the Charlotte group,an average 0.05 increase among the nonreaders．
The idea behind the study,says Dr Sarah Armstrong,director of Healthy Lifestyles,was to find a
way to encourage the girls without adopting the restrictive and often authoritative voice of so many
other nutrition and diet programs．Lake Rescue was the perfect instrument,says Armstrong；it
presentsa likable character to whom the girls could relate and whom they could learn from．As the
book progresses,its protagonist learns to make healthier lifestyle choices and finds an advisor to help
keep her on track．
Armstrong says,"She learns that she can become healthier,and the 'I can do it'
feeling resonates (产生共鸣) with the teenage girls．"

Should ecigarettes (electronic cigarettes) be a new choice for the smokers trying to get rid
of the habit? Reactions from Americans are mixed．More than half of the people questioned in
a survey think ecigarettes should be controlled by the US Food and Drug Administration,but 47
percent believe the ecigarettes should be available to the smokers who want to quit．
"In the hunt for a safer cigarette,ecigarettes are becoming a popular choice among those either
trying to quit or looking to replace standard tobacco smoke with an alternative that manufacturers
claim to be safer," Zogby International,which conducted the survey,said in a statement．
About half of the 4,611 adults who took part in the survey had heard about ecigarettes,which
are batterypowered,or rechargeable cigarettes that vaporize a liquid nicotine solution．They do not
produce smoke but a water vapor without smell．Sold mostly on the Internet,ecigarettes were first
made in China．
Last year the World Health Organization (WHO) warned against using ecigarettes,saying there
was no evidence to prove they were safe or helped smokers break the habit．The WHO said people
who smoke ecigarettes breathe in a fine fog of nicotine into the lungs．
Nearly a third of people questioned in the survey think that ecigarettes should be allowed in places
where smok
ing is forbidden,because they don't produce smoke,but 46 percent disagree．Men who
were aware of the availability of ecigarettes were more likely than women to say they should be a choice
available to sm
okers who want to quit．Young people,aged 18－29,and singles were the groups most
open to trying ecigarettes．Smoking is the single largest cause of preventable death worldwide,according
to the WHO．

| Sometimes people call each other "scared-cat",but have you ever thought about this expression? When a cat is frightened,its heart starts beating faster,its muscles get tense,and there are changes in the chemicals in its blood- stream. Although the cat doesn't 1 this,its body is getting ready for action. If the danger continues,this animal will do one of the two things .It will 2 itself,or it will run away as fast as it can. 3 ,when people are excited,angry,scared,or aroused by other emotions,our bodies also go through many 4 changes. Our hearts beat faster,and our muscles get tense. All of these changes make us more alert and ready to react. We,too,get ready to defend ourselves 5 run. Human beings, 6 ,have a problem that animals never face. If we give way to our feelings and let them 7 ,we can get into trouble.

Both warm-blooded and cold-blooded desert animals have ways to escape the desert heat.
Warm- blooded desert animals, such as rats and mice, rest during the day, often staying in cool
underground burrows. At night they search for food. Animals that are out during the day, such as
cold-blooded lizards and snakes, are active only for short periods. As their body temperature rises,
these reptiles(爬行动物) move into the shade in order to cool down. In the early evening, when
the sun grows weaker, the reptiles become more active and begin their search for food again.
Getting enough water to survive is a major problem for all desert animals. Some desert animals,
like desert birds, manage to find water holes. Other desert animals, such as the kangaroo rat and the
related jerboa, get water only from the food that they eat. Because these animals eat mainly dry seeds,
they must survive on a tiny amount of water.
Most deserts have only a small number of frogs and toads because these animals must be near
water to survive. Yet even these creatures have adapted(适应) to desert conditions. When small
amounts of water collect in temporary streams, the desert-living frogs and toads become active.
After a rainfall, they lay their eggs. The eggs grow into tadpoles in a few days and into adults in just
four weeks. When the puddles(水坑) dry up, the adult frogs or toads dig into the ground. Their metabolism(新陈代谢) slows, and they stay beneath the ground until the next rain, which may be as good as
a year away. Until then, their bodily activities continue at a reduced rate.
The camel - often called the ship of the desert - is one of the most successful desert animals. Camels
can go for long periods without water, but eventually they must drink. When water becomes available
to them after a long drought, they may drink 95 liters of water or more. When water is not available,
what helps camels survive the desert heat is the fat stored in their humps(驼峰). A camel's hump contains
about 12 kilograms of fat. Fat is rich in hydrogen. As the fat is digested, hydrogen from the fat combines
with oxygen in the air that the camel breathes. The result is H2O, or water. Each kilogram of fat that a
camel digests produces about a liter of water.

Money is the root of all evil- and new study claims there may be some truth behind the saying. Scientists at the University of California, Berkeley, US, 1 on February 27 that rich people are more likely to do 2 things, such as lie or cheat, than poorer people. The scientists did a series of eight experiments. They 3 their findings online in the Proceedings of the National Academy of Sciences (PNAS). They carried out the first two experiments from the sidewalk near Berkeley. They noted that drivers of newer and more expensive cars were more likely to cut off other cars and pedestrians at crosswalks. Nearly 45 percent of people driving expensive cars 4 a pedestrian compared with only 30 percent of people driving more 5 cars. In another experiment, a group of college students was asked if they would do unethical(不道 德的) things in various everyday situations and 6 included taking printer paper from work and not telling a salesperson when he or she gave back more 7 . Students from higher-class families were more likely to act dishonestly. According to the scientists, rich people often think money can get them out of trouble. This makes them less afraid to take risks. It also means they care less about other people's feelings. Finally, it 8 makes them greedier . "Higher wealth status seems to make you want even more, and that increased want leads you to bend the rules or break the rules to serve your self-interest," said Paul Piff, lead scientist of the study. Piff pointed out that the findings don't mean that all rich people are untrustworthy or all poor peoplehonest. He said the experiments were to show how people living in different social situations express their 9 and values in different ways. |
