Polar bears depend on ice to hunt (猎取)for food in the Arctic Ocean. They climb up on the ice to look for seals and other animals. But scientists say sea ice is decreasing (减少)because of climate change. They say rising temperatures have reduced the area in which polar bears can hunt.
Recently, a number of studies found that future reductions of sea ice could result in a loss of many polar bears within fifty years. The studies found a direct link between sea ice in the Arctic Ocean and the health of polar bears. The scientists say the animals will disappear from the north coasts of Alaska and Russia in the next fifty years. The only polar bears to survive will be in Canada's far north and the west coast of Greenland.
The scientists found that almost two thirds of the world's nineteen polar bear populations will disappear from the earth by the middle of this century. The studies showed that three more groups of polar bears will disappear within seventy-five years.
Scientists say polar bears still can be saved. But they say the world must begin taking steps to reduce climate change to do this. The center for Biological Diversity says governments around the world need to reduce the release (释放)of pollution like C02 gas.
Scientists say one step toward this goal would be to include polar bears on America's list of endangered species. Then the government would be able to make sure that industrial activities do not threaten their survival. The United States Fish and Wildlife Service is expected to examine the new findings when it considers whether polar bears should be included on the Endangered Species List.

Thanksgiving time came and all the relatives were gathered around the long table, or seated behind TV trays．The television was on and some folks were watching it while visiting with one another．Something on television got their attention and one of the adults said, "Listen at it!" Someone else replied．"Well, if that don't beat all．"
Simple phrases were spoken by folks whose language was simple and brief．They had several idioms that were just as colorful; Phrases and words that brightened the room and warmed the conversation．In school we were taught to speak differently．The way our relatives spoke was discouraged．Sometimes our parents would say things we weren't taught in school．They'd often correct themselves, as if getting rid of a mistake．Of course we learned some of their phrases and used them．They were comfortable words to pronounce, familiar．
Our father's side of the family was from Arkansas and Oklahoma and they spoke with the accents native to their birth states．Their voices musical and often high , it was easy to pick up that effect in our own speech and at school my brother and I were often teased for the way we spoke．Our mother's side of the family came from Illinois and they had a tendency to talk fast．They had an accent, too, and my brother and I added that to our own speech, confusing the kids at school all the more．Our father's side of the family loved to laugh and have a good time．Our mother's side of the family was more serious about how they took life in; their joys more silently experienced and enjoyed．It was a rich picture of culture and it gave my brother and me a colorful view in life．
Thanksgiving holiday was always an easy comfortable going day．It was the first real holiday of the season when everyone came together in one place, and a good time was spent happily together by all．

Each year, prizes are presented to adults who accomplish great things in art, writing, science, and economics．So why not give awards to kids?
Harry Leibowitz asked himself that question in 1996．As an answer, he and his wife, Kay, created the World of Children organization and began handing out awards to kids and adults whose work has helped kids all over the world．The awards World of Children presents are nicknamed the "Children's Nobel Prize．" On Thursday, World of Children honored six adults and two kids at its 11th Annual Changemakers for Children awards ceremony held at the UNICEF House at United Nations Plaza in New York City．
Talia Leman, from Iowa, was awarded a Founder's Youth Award for Leadership．She is only 13 years old, but she has accomplished a lot．In 2005, she founded "RandomKid．" Since then, the nonprofit organization has raised more than $10 million to help kids in 48 states in the U．S．and in 19 other countries develop funding solutions to real-world problems．One place helped by RandomKid was a school built in Cambodia to enable 300 kids to go to school．The organization has also helped fix a school for 200 kids in Slidell, Louisiana, and provided interactive play centers that serve more than 500 kids in hospitals in Iowa．In faraway places like Africa, RandomKid has provided money for the purchase of water pumps．
Talia never thought that the organization she founded would be as successful as it has become．"I did a project called TLC, which meant Trick or Treat for the Levy Catastrophe, where kids would trick-or-treat for coins along with getting candy," she told me．"My goal was to raise $1 million．That seemed really high, but when you reach a goal, you always wind up reaching higher--and we actually raised $10 million．" The money RandomKid raised provided help to the victims of hurricanes Katrina and Rita．

The United States government wants to know what the public thinks about its findings on the safety of cloned animals．
The Food and Drug Administration says meat and milk from clones of adult cattle, pigs and goats are safe to eat．An FDA official called them “as safe to eat as the food we eat every day．” And when those clones reproduce sexually, the agency says, their offspring(后代)are safe to eat as well．But research on cloned sheep is limited．So the FDA proposes that sheep clones not be used for human food．
The United States this year could become the first country to agree to the sale of foods from cloned animals．First, however, the public will have ninety days to comment on three suggested documents．On December 28th the FDA released a long report, called a draft risk assessment, along with two policy documents．
The agency says it must receive comments by April second．The FDA seemed ready to act several years ago, but a committee called for more research．
For now, the government will continue to ask producers to honor a request that they not sell foods from cloned animals．
Clones are still rare．They cost a lot and are difficult to produce．
The FDA says most food from cloning is expected to come not from clones themselves, but from their sexually reproduced offspring．It says clones are expected to be used mostly as breeding animals to spread good qualities．
Public opinion studies show most Americans do not like the idea of food from cloned animals．But this research also shows the public knows little about cloning．
Cloning differs from genetic engineering．A cell taken from a so-called donor animal is grown into an embryo(胚胎) in the laboratory．Next, the embryo is placed into the uterus(子宫) of a female animal．If the process is successful, the pregnancy reaches full term and a genetic copy of the donor animal is born．
60．What’s the main purpose of the passage?

Tamiflu does not kill but prevents H1N1 from further proliferation (繁衍) till the virus limits itself in about 1-2 weeks (its natural cycle)．H1N1, like other Influenza A viruses, only infects the upper respiratory tract and proliferates (only) there．The only way of entry are the nostrils(鼻孔) and mouth/ throat．In a global epidemic of this nature, it's almost impossible not coming into contact with H1N1．
Contact with H1N1 is not so much of a problem as proliferation is．
While you are still healthy and not showing any symptoms of H1N1 infection, in order to prevent proliferation, some very simple steps can be practiced:
1．Frequent hand-washing．
2．"Hands-off-the-face" approach．Resist all temptations to touch any part of face (unless you want to eat or bathe)．
3．Gargle(漱口) twice a day with warm salt water (use Listerine if you don't trust salt)．H1N1 takes 2-3 days after initial infection in the throat/ nasal cavity to proliferate and show characteristic symptoms．Simple gargling prevents proliferation．In a way, gargling with salt water has the same effect on a healthy individual that Tamiflu has on an infected one．Don't underestimate this simple, inexpensive and powerful preventative method．
4．Similar to 3 above, clean your nostrilsat least once every day with warm salt water，Which is very effective in bringing down viral population．
5．Strengthen your natural immunity with foods that are rich in Vitamin C ．If you have to supplement with Vitamin C tablets, make sure that it also has Zinc to boost absorption．
6．Drink as much of warm liquids as you can．Drinking warm liquids has the same effect as gargling, but in the reverse direction．They wash off proliferating viruses from the throat into the stomach where they cannot survive, proliferate or do any harm．
7．All these are simple ways to prevent, within means of most households, and certainly much less painful than to wait in long queues outside public hospitals．
57．What part of a person’s body do H1N1flu viruses mainly infect?

The words of Gandhi, Einstein and other great thinkers are to be quoted in service announcements on London’s Underground．
Transport for London has asked Turner Prize-winning artist Jeremy Deller to edit a list of mottos to be used by tube drivers．Gandhi’s “there is more to life than increasing its speed” and the artist Cezanne’s “we live in a rain-bow of chaos” are among the quotes．Deller hopes they will make passengers’ journeys a bit more thought-provoking(发人深省的)．
Deller’s original plan was to abolish all public announcements for a day．“It makes me feel annoyed,” he said．“It’s like some psychological warfare(战争 ) on the passengers．”
But his idea was refused by the manager of Transport for London, who instead agreed to the plan of replacing some announcements with something more human and attractive．
Sally Shaw, who is running the scheme for Transport for London, says it is part of an attempt to improve day-to-day interaction and rely less on automated announcements．
“I think everyone has their own little philosophy on their journeys．And if we can get more of that out in the air, that would be great,” she said．
Susy Wells, one of the drivers to test the idea out on the London Underground, is also enthusiastic about it．
She said, “I like to make my own announcements and it’s nice to get passengers to think as well．”
What’s more, some quotes are helpful to the drivers．They help the passengers become more understanding about the drivers’ work．
The quotes such as Thomas Fuller’s “a stumble(绊脚) may prevent a fall” are popular for helping explain why a little inconvenience was sometimes necessary to keep the system safe．
53．The underlined phrase “tube drivers” probably means______．
A．taxi drivers B．subway drivers C．truck drivers D．bus drivers
54．Why did Deller want to abolish all public announcements on the underground?
A．Because they cause a war among passengers．
B．Because the public announcements make Deller tired．
C．Because the public announcements are dull．
D．All public announcements are not suitable for the passengers．
55．The reason why the sayings are to be quoted on London’s Underground is ______．
A．that everyone has their own life motto
B．that sayings are believed to be more human and attractive
C．that sayings can help develop spiritual civilization in London
D．that saying can make drivers think more
