Dolphins and sharks are showing up in surprisingly shallow water just off the Florida coast. Mullets, crabs,
rays and small fish gather by the thousands off an Alabama pier. Birds covered in oil are crawling deep into
marshes (沼泽), never to be seen again.
Marine scientists studying the effects of the BP disaster (英国石油公司漏油事件) are seeing some strange
phenomena. Fish and other wildlife seem to be fleeing the oil out in the Gulf and clustering in cleaner waters
along the coast in a trend that some researchers see as a potentially troubling sign. The animals" presence close
to shore means their usual habitat is badly polluted, and the crowding could result in mass die-offs as fish run
out of oxygen. Also, the animals could easily be captured by their enemies.
The nearly two-month-old spill (漏油) has created an environmental disaster in US history as tens of millions
of gallons have flown into the Gulf of Mexico ecosystem. Scientists are seeing some unusual things as they try
to understand the effects on thousands of species of marine life.
For nearly four hours Monday, a three-person crew with Greenpeace cruised past delicate islands and
mangrove-dotted inlets in Barataria Bay off southern Louisiana. They saw dolphins by the dozen frolicking (嬉
戏) in the oily sheen (光泽) and oil-tinged pelicans feeding their young. But they spotted no dead animals.
"I think part of the reason why we"re not seeing more yet is that the impacts of this crisis are really just
beginning," Greenpeace marine biologist John Hocevar said.
The counting of dead wildlife in the Gulf is more than an academic exercise; the deaths will help determine
how much BP pays in damages.

The move is aimed at controlling the number of deaths from smoking-related diseases, running at a million
a year.
But the rules have been criticized, because they do not include punishments for those who choose to ignore
them.
Many business owners hate rules that force them to ban smoking on their premises (经营场所) because
many customers do not like the rules and complain.
The rules do not allow smoking in places like restaurants, hotels, railway stations or theatres, but not at the
office.
Employers have a duty to warn staff off the dangers of smoking but do not have to forbid them from
lighting up at their desks.
Shanghai introduced similar rules a year ago, but people do not seem to take much notice of them. Often
you find people smoking at the next table while you are eating your meal or having a drink in a bar. The
problem is that the rules do not include punishments for businesses or individuals who ignore them.
It appears that many Chinese people are unaware of the dangers of smoking. Research suggests that only
one in four knows the harm cigarettes of second-hand smoke can cause.
Officials say they have to try to persuade people not to smoke to reduce the numbers dying from
smoking-related diseases.
At the same time the government makes a lot of money from the sales of cigarettes by the state-owned firm
that makes and sells all tobacco products throughout the country.
B. 44%
C. 33%
D. 55%
B. are curious about
C. don"t know
D. don"t care
B. Because they do not include punishments for those who choose to ignore the rules.
C. Because the rules are ignored by all the people who smoke.
D. Because nobody takes notice of the rules.
B. take more effective measures
C. do punish those who ignore the rules
D. let people know more about the dangers of smoking
●Stop getting junk mail. Billions of junk mail can be sent every year. Half of it is never opened Get-your
name off mailing lists. If 100,000 people stopped getting junk mail today, it would save 150,000 trees a year
●Stop reading newspapers. All over the world, millions of newspapers are thrown away every day,44
million newspapers in the USA alone-that"s half amillion trees a week. Either recycle your newspapers or read
the news online.
●Buy clothes made from organic materials. Conventional cotton farming seriously pollutes the environment, most of which uses chemical pesticides (农药) and fertilizers. Organic is better!
●Switch to solar energy. In one day, the sun will provide enough energy to power the planet. Why aren"t
we using it?
●If you have to drive, share the ride. Most cars in the USA have only one occupant. Also, 25 percent of car
rides are less than 1.5 kilometres. Get out and walk!
●Unplug your PC, TV and VCR. Simply turning them off isn"t enough Sets left on standby are still using 25
percent of their power.
●Hold on to your balloons. Helium-filled balloons which fly away usually end up in a lake or river, where
they can choke aquatic (水生的)creatures. Save your balloons and use them again. Or better still, don"t use
them at all.
●Feed the birds. Wild birds need food, especially in winter when other sources can be scarce. The greater
the range of foodstuffs you put out for them, the more types of birds you will attract.
●Plant a garden at your school. Learn the connection between the land and the table. Plant vegetables to eat,
flowers to admire and trees to improve the air.
B. To suggest some ways how to make full use of solar energy.
C. To advise protecting environment and saving energy.
D. To advise on how to recycle waste and save energy.
B. ready to be turned off
C. ready to be repaired
D. ready to be put away
B. Don"t accept junk mail.
B. Read your newspaper online.
D. Read only one newspaper
not clear, researchers say, whether television itself is the reason, but it is possible that things like snacking in
front of the TV or seeing ads for junk food influence young people"s diets.
[2] The study included nearly 1,400 high school students. It showed that those who watched TV for five
hours or more every day had less healthy diets than other students five years later. As a group, they ate fewer
fruits and vegetables, but ate more fast food, snack products and fried foods.
[3]"We"re not able to tell why," lead researcher Dr. Daheia J. Barr-Anderson said."But we have some
speculations(推测)." People who spend a lot of time in front of the TV, especially teenagers, may have more
snack. It may influence their long-term diet quality. It"s also possible that TV ads for fast food, sweets and
snacks make teenagers eat more of those foods. TV time might also replace exercise time for some kids.
[4] The researchers found a clear relationship between TV time during high school and diet quality of the
young. The heaviest TV viewers five years later, and those who"d watched fewer than two hours every day
had the most fruits and vegetables.
[5] According to Barr-Anderson, the findings support experts" advice that children should watch no more
than two hours of television every day."Parents should cut the TV time." Barr-Anderson said. She advised that
parents set a good example by eating right, being physically active and controlling their own TV time.

noticed in 1858 by William Farr, who wrote that widows (寡妇) and widowers (鳏夫) were at a much higher
risk of dying than the married people. Studies since then suggest that marriage could add as much as seven
years to a man"s life and two to a woman"s. The effect can be seen in all causes of death, whether illness,
accident or self-harm.
Even if the chances are all against you, marriage can more than compensate (补偿) you. Linda Waite of the
University of Chicago has found that a married older man with heart disease can expect to live nearly four years
longer than an unmarried man with a healthy heart. Similarly, a married man who smokes more than a pack a
day is likely to live as long as a divorced man who doesn"t smoke. There"s a flip side, however, as partners are
more likely to become ill or die in the couple of years following their husband or wife"s death, and caring for
your husband or wife with mental disorder can leave you with some of the same severe problems. Even so, the
chances favour marriage. In a 30-year study of more than 10,000 people, Nicholas Christakis of Harvard
Medical School describes how all kinds of social networks have similar effects.
So how does it work? The effects are complicated, affected by socio-economic factors, health-service
provision, emotional support and other more physiological mechanisms (生理机制). For example, social contact can promote development of the brain and immune (免疫) system, leading to better health and less chance of
depression later in life. People in supportive relationships may handle stress better. Then there are the
psychological benefits of a supportive partner.
A life partner, children and good friends are all recommended if you aim to live to 100. The overall social
network is still being mapped out, but Christakis says:"People are inter-connected, so their health is
inter-connected."
