Sleep might be one answer to the problem. A new study has found that elementary school students who slept too little were more likely to gain pounds.
Past studies have shown a link between sleeping less and weighing more, but scientists have had a
tough time determining "which came first, the chicken or the egg," says Julie C. Lumeng of the University of Michigan.
To get a better idea of which causes which, Lumeng and colleagues interviewed the parents of 785
third graders from around the United States. The parents answered questions about how well their kids
slept that year. Three years later, the parents answered the same questions.
By sixth grade, 18 percent of kids involved in the study were obese (肥胖的) . The scientists found no relationship between weight and the students" race or gender (性别). It also didn"t matter how strict their
parents were, or whether they were boys or girls. Obesity struck all of these groups equally.Instead, sleep seemed to be the key factor. Over the 3 years of the study, the children averaged a healthy 9.5 hours of
sleep a night. Some kids, however, slept a lot more-- or less-- than others.
For the sixth graders, every hour of sleep above the 9.5-hour average was linked to a 20 percent lower risk of being obese. Sleep appeared doubly important for the third graders. Every extra hour of sleep they got was linked to a 40% drop in obesity by sixth grade.
"I expected we"d find that this sleep link with obesity was just a bunch of nonsense." says Lumeng, a
pediatrician (儿科医生). But their findings were convincing. No matter how her team looked at the link, "we couldn"t make it go away."
A.More and more kids put on weight.
B. 18% of the six graders were very fat.
C.9.5 hours of sleep a night is harmful.
D. Parents should be strict with their children.

A. the sixth graders need more sleep than the third graders
B. the third graders need more sleep than the sixth graders
C. boys and girls were quite different in sleeping hours
D. after three years" study, the children had healthy sleeping hours
3. What does the word "it" in the last line of the last paragraph refer to?
A. Julie C. Lumeng"s team.
B. The conclusion of the study.
C. The relation between less sleep and less weight.
D. The relation between more sleep and less weight.
4. What is the best title for the passage?

that causes AIDS. According to the report, this means every eight seconds somebody in the world is
infected with HIV, resulting in 11,000 people becoming newly infected every day.
The director of UNAIDS, Peter Piot, says most of the new infections, nearly two-thirds, are in
Sub-Saharan Africa. But, the biggest increases are in Eastern Europe and Central Asia, where infection
rates have risen by more than 50 percent since 2004. He says 2.9 million people died from AIDS-related
illnesses this year, the highest number ever.
UNAIDS senior epidemiologist(流行病学家), Karen Stanecki, says infections are rising in countries
where HIV prevention programs have not adapted to the changing nature of the epidemics(流行病).
Stanecki noted,"In Thailand, one of our past success stories, a large percentage of new HIV infections
are occurring in people considered to be low risk. One third of new infections are among married women."
It says data shows increased use of condoms has resulted in drops in HIV prevalence(流行) among
young people between 2000 and 2005 in a number of African countries, including Botswana, Kenya and
Zimbabwe. Nevertheless, the report notes young people between the ages of 15 and 24 account for 40
percent of new HIV infections. It finds the risk behavior, such as injecting drug use, homosexuals, is a
factor of concern in many regions of the world, especially in Asia, Eastern Europe and Latin America.
The report notes the emergence (出现) of injecting drug use as a factor of HIV in Kenya, Tanzania,
Nigeria and South Africa is a recent development in Sub-Saharan Africa.
B. 2.9 million.
C. 3.5 million.
D. 4 million.
B. Eastern Europe
C. Central Asia
D. both A and B
B. said angrily
C. fully noticed
D. uttered weakly
B. Two fifths of the new infections are among young people aged 15 to 24.
C. The risk behavior, such as injecting drug use and homosexuals, exists in many parts of the world.
D. Injecting drug use occurs in many African countries.
B. The AIDS epidemic continues to grow in the world.
C. The AIDS epidemic has been reduced in the world.
D. No one can tell when the AIDS epidemic will be completely controlled.
bark(树皮). The groove 2_________(deep) over the years. Though for whatever reason, it did not kill the
tree.
3_______ some years, the family took their bull away. They cut the chain, leaving the loop around
the tree and one link 4_________(hang) down.
Then one year, agricultural catastrophe stuck Michigan in 5______ form of Dutch elm disease. All
the elms lining the road leading to the farm became infected 6______ died. Everyone thought that the old
elm would be the next. The farm owner considered 7_______(go) the safe thing: pulling it out and
chopping it up into firewood before it died.
8__________(amazing), the tree did not die. Nobody could understand 9_______ it was still the
only elm standing in the country. It is said that 10_____ doesn`t kill you will make you become stronger.
Or, as a plant pathologist(病理学家) put it, “ Life breaks us all, but afterwards, many of us are strongest
at the broken palces.”
Americans think that travel is good for you. Some even think it can help solve one of the country’s
worst problems - crime (犯罪).
Crime worries a lot of people. Every year, the number of crimes goes up and up. And many criminals (罪犯) are young. Most of them - 85 percent are boys. They often come from sad homes, with only one
parent or no parents at all. There are problems with alcohol and drugs.
There are many young criminals in prison. But prison doesn’t change them - 60 to 70 percent will go
back to crime when they come out of prison.
One man, Bob Burton, thought of a new idea. In the old days, young men had to live a difficult life on
the road. They learned to be strong and brave, and to help their friends in time of danger. This helped them to grow into men. So Bob Burton started "Vision Quest".
He takes young criminals on a long, long journey with horses and wagons 3,000 miles through seven
states. They are on the road for more than a year. The young people on Vision Quest (boys and a few
girls) all have bad problems. Most of them have already spent time in prison. This is their last chance.
It’s hard work on the road. The day starts before the sun comes up. The boys and girls have to feed
the horses. Some of them have never loved anyone before. But they can love their horses. That love can
help them to have a new life.
Not all young people on Vision Quest will leave crime behind them. 30 or 40 percent will one day be in prison again. But that’s a lot better then 60 or 70 percent. Bob Burton is right. Travel can be good for youEven today, Americans still say, "Go west, young men".

Strategy 1: Bring your own cup to Starbucks
You"ll get a 10 cent discount, and it"s one less paper cup to end up in a landfill. While you"re there, pick
up some free bags of spent coffee grounds to use as "green" fertilizer in your garden.
The payoff: 2
Strategy 2: Turn off your computer
When in standby mode, your PC is still using energy. 3
The payoff: Turning off a monitor for 40 hours a week may only save $5 a month, but it reduces CO?
by 750 pounds.
Strategy 3: Reuse plastic bags
Instead of throwing away 100 billion plastic bags a year, try and get a second, third, or tenth use out of
them. Better yet, next time you shop, try a reusable bag.
The payoff: 4 The amount of oil it would take to make just 14 plastic bags would run your car for one
mile.
Strategy 4: Use recycled paper in the bathroom
Most of the toilet paper we use is made from trees found in forests previously untouched by humans.
The payoff: If every household replaced one roll of toilet paper with a recycled one, 424000 trees
would still be standing. Look for eco paper towels too.
Strategy 5: Buy energy-efficient appliances(电器)
Replace the old fridge with an Energy Star appliance and you"ll use 15 percent less energy. 5 .
The payoff: If we all used one Energy Star appliance at home, it would be like planting 1.7 million acres of new trees.

Then you are probably quiet, shy, and you would rather follow than lead. You tend to be pessimist. At
least, this is what psychologists tell us, and they should know, because they have been seriously studying
the meaning of colour preference, as well as the effect that colours have on human beings. 2 . If you
happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could
see clearly.
3 . A yellow room makes most people feel more cheerful and more relaxed than a dark green one;
and a red dress brings warmth and cheer to the saddest winter day. 4 . A black bridge over the
Thames River, near London, used to be the scene of more suicides(自***) than any other bridge in
the area - until it was repainted green. The number of suicide attempts immediately fell sharply.
Perhaps it would have fallen even more if the bridge had been done in pink or baby blue.
5 . It is an established fact that factory workers work better, harder, and have fewer accidents
when their machines are painted orange rather than black or grey.
