The Arctic Ice is Thawing
Father Christmas may have to move his"workshop"from the North Pole because global warming is thawing the ice beneath his feet and his reindeers' feet as well.His"workshop"is in dire straits. The"platform"for the"workshop"is melting,said Stefan Norris of the World Wildlife Fund Environmental Group's Arctic Program.
An eight-nation report by 250 scientists published recently predicted the Arctic Ocean could be ice-free in summer by 2100 because of a build-up of heat-trapping gases in the atmosphere,mainly from burning fossil fuels in cars or factories.The North Pole is getting more and more inhabitable to Father Christmas._______(46)Young people learn that,Father Christmas'"workshop"produces millions of gifts delivered by him on a flying,reindeer-drawn sleigh.Hollywood movies like The Polar Express tried to make viewers believe that Father Christmas lives at the North Pole._______(47)
The"Fortress of Solitude"is near the North Pole that could be under threat in a warmer world.
Ian Boldt,spokesman of the Danish Ministry of Science,suggested ways to rescue Father Christmas. _______(48)Another alternative,he argued,would be building some electrical facilities to ensure the ice stays on the North Pole for him."This should be a subject for the United Nations."he said. "Danmark could build windmills to provide Father Christmas with power."Denmark says Father Christmas's real home is Greenland,which will help,Denmark thinks,to strengthen its position in claiming the sovereignty over the Pole._______(49)
"Doesn't he already speak Danish?"Boldt said frostily when asked if Father Christmas would be forced to learn Danish if Denmark won international recognition of its claim to the Pole.Last month's Arctic report said the region is warming twice as fast as the rest of the globe,partly because dark ground or water,once uncovered,soaks up more heat than ice or snow. Finland has been most favored by Father Christmas and it has about 500,000 tourists a year to visit its Christmas center in Rovaniemi in Lapland._______(50)
__________（50）
A:However,Nordic nations all reject it by claiming that their countries are his home.
B:Therefore the North Pole is the most attractive place in the world.
C:If Denmark's claim were accepted internationally,it would have the legal right to search for oil and gas at the North Pole.
D:One of them would be building a giant floating ice rink for the workshop if the Pole thaws.
E:Maybe Father Christmas has already moved to Rovaniemi.
F:He may have to move from the North Pole within one children's lifetimes.

Hurricane
1 A hurricane（飓风）is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral（螺旋）around a relative calm center know as the“eye”.The“eye” is generally 20 to 30 miles wide,and the storm may ex- tend outward 400 miles. As a hurricane nears land,it can bring heavy rains,high winds,and storms（风暴潮）.The storm surges and heavy rains can lead to flooding.
2 Hurricanes are given a different label,depending on where they occur. If they begin over the North Atlantic Ocean,the Caribbean Sea,the Gulf of Mexico,or the Northeast Pa-cific Ocean,they are called hurricanes.Similar storms that occur in the Northwest Pacific Ocean west of the International Date Line are called typhoon. Near Australia and in the India Ocean, they are referred to as tropical cyclones（龙卷风）.
3 When a hurricane hits land,it can do great damage through its fierce winds,heavy rains , inland（内陆的）flooding, and huge waves crashing onto the shore. During a hurri-cane,homes,businesses,and public buildings may be damaged or destroyed;road and bridges can be washed away. A powerful hurricane can kill more people and destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives and not be able to get to a safe harbour if they do not receive adequate warning.
4 If a hurricane is coming in your area,the most important thing is to stay calm and find shelter immediately. Go to your safe room. If you do not have one,stay indoors during the hurricane and go to a safer place near the center of your home. Cover yourself with a blanket and be sure to keep away from windows and glass doors,because if the glass breaks it's real-ly dangerous. Do not be fooled if there is a lull（暂停）；it could be the eye of the storm-winds will pick up again.
A powerful hurricane may become the most destructive________.
A: inland flooding
B: natural disaster
C: early warning
D: windows and glass doors
E: a constant speed
F: different labels

Cancer Drug Trials Often Halted Early
An increasing number of clinical trials for new cancer treatments are being halted before the risks and benefits have been fully evaluated,say Italian researchers,who warn that this growing trend could put patients at risk of harm from new therapies rushed into use.
The researchers looked at 25 randomized,controlled clinical trials that were stopped ear-ly because the treatments had started to show benefit to patients.
“When we analyzed 25 trials over a 10-year period between 1997 and 2007,we found a consistent increase in prematurely stopped trials一more than 50 percent were stopped within the last three years,”study co-author Giovanni Apolone said at a news conference Tuesday.
Of 14 trials halted early and published between 2005 and 2007,the researchers found that 11(79 percent)of them were used to support drug approval applications submitted to the European Medicines Agency and the U.S.Food and Drug Administration.
“This suggests a strong commercial component in stopping trials prematurely.In fact, this strategy could guarantee quicker access to the market for companies.On the other hand, a quicker clinical drug development may lead to an ‘immature’benefit/risk balance of new drugs,”Apolone said.
He and his colleagues“are aware that trials stopped early because they are showing ben-efit may result in identification of promising new treatments for patients.However,findings obtained following this strategy should be considered to be preliminary results that require subsequent confirmation.”
It can take several years for the long-term benefits or harmful side effects of a new treat-ment to become apparent, Apolone noted, but the average duration（持续时间）of the 25 studies he and his colleagues analyzed was 30 months,with a range from 12 to 64 months.
They also found that at the time five of the studies were stopped,they'd enrolled less than 40 percent of the total number of patients planned for final analysis.
“Clinical trials need to stop early for superior benefit whenever there's proof beyond rea- sonable doubt that the new treatment really is superior.That would be an ethical obligation,” Stuart Pocock,a professor of medical statistics at the London School of Hygiene and Tropi-cal Medicine in the United Kingdom,said at the news conference.“However,too many trials are stopped early claiming efficacy（功效）without strong evidence being available.”
Stuart Pocock believed that in no case should clinical trials stop early.

Early Ideas about the Universe
1 Early man got his ideas about the universe by looking at the stars as you do.He
observed carefully,and learned many things about the sun,the moon,and the stars.
2 Suppose you were asked to collect evidence about the sun as early man did.You might
go out morning after morning and see it come up in the east.Even on cloudy mornings,you
would observe that the darkness goes away and the world becomes light.You might not see
the sun but would be sure it is there,because you notice that the earth warms up.As you
continued,the sun climbs higher in the sky each day during part of the year. It stays in the
sky longer. The earth gets warmer. Things begin to grow. It is spring and then summer.
3 After a while the sun stays in the sky for shorter and shorter periods.Many plants begin
to die.Leaves fall.Winter comes.Year after year this is repeated and you cannot tell
exactly why it happens.But you realize that the sun seems to make the difference.
Primitive（原始的）man felt that since the sun was so powerful it must be a god. It may
seem silly to us now to worship（崇拜）a sun-god, but primitive man was right about the
importance of the sun to life on earth.
4 You have been told that the world is round.But suppose no one had ever taught you
that the world was like a huge ball.Would you have ever thought of it yourself?You cannot
see the curve（曲线）of the earth at once. You would have no idea of how big it was.
That's why early man believed that the earth was small and flat.Such ideas appeared from
the evidence they had.
5 If you watch the stars night after night,you will see them rise and set.As you look at
the sky,it is not difficult to imagine that you are in the center of a vast collection of twinkling
（闪烁）lights. Some early astronomers（天文学家）believed the sky was a crystal shell or
series of crystal shells,one inside the other. They believed this because that is what the
night sky looked like.For many centuries,men believed that the earth was the center of
the universe and that the sun,the moon,and the stars circled around it.
Early man thought the earth was the center of the universe because_________.
A:he did not observe the sun carefully enough
B:he could not see its curve
C:the sun,the moon and the stars seemed to move around it
D:the earth circles around the sun

Motion Sickness
Living in space looks like lots of fun.You can do certain things in space(like floating
around,or pushing huge objects)that you cannot do on earth.But being in space can do
things to you,too.If you stay too long in a gravity-free environment,your bones could
become weak,and a small spaceship just might annoy you after a while,because space
travel could make you seasick!
On July 4, 1982,after seven days orbiting the earth,astronauts Thomas K. Mattingly
and Henry W. Hartsfield returned home.Although not all of the experiments on board
worked properly,the flight basically seemed to be a success except for one"little"thing:
early in the flight,astronaut Hartsfield became"seasick".
Thomas Mattingly,who is also a jet pilot and is highly resistant to motion sickness on
earth,did much better.Mattingly sailed through space with a steady stomach.But no one
knows why Hartsfield felt uneasy and Mattingly did not.
So far it seems there is no reliable way to predict who will become motion sick in
outer space and who will not.In all,at least four astronauts have suffered from space
motion sickness. Russian and American scientists are working together to try to
understand and solve the motion sickness.Space program officials worry that if so
many highly-trained pilots get sick in space,what will happen when civilians start flying
in the shuttle?
Motion sickness is a disagreeable feeling that comes from the pitching,rolling,
swaying,or just the moving of the object you are riding in or on.Symptoms of motion
sickness include:dizziness,headache,a sinking feeling in the stomach,and vomiting
（呕吐）.
Why does motion make some people ill?
Doctors believe that motion sickness is caused by a disturbance in the inner ear.Our
ears do more than give us hearing.A part of the ears gives us a sense of balance and helps
make us aware of whether we are right side up or upside down.
If you know that you get carsick or seasick,what can you do?
Speak to your doctor. There are certain medicines available that can help stop that
uneasy feeling.But many of them can also make you sleepy.Usually they work best taken
before you begin feeling ill.
Some people also recommend water,ice cubes,mints,or plain toast.But these
remedies do not always work for everyone.
Perhaps,since motion sickness is such a big problem in outer space,researchers
may soon find a way to cure the astronauts一and those of us who stay on earth.
At the end of the flight,Hartsfield became"seasick".

As many as 20% of all children in the United States suffer from some form of the learning disorder called dyslexia.
Experts on dyslexia say that the problem is not a disease.They say that persons with dyslexia use information in a different way.One of the world's great thinkers and scientists,Albert Einstein was dyslexic.Einstein said that he never thought in words the way that most people do.He said that he thought in pictures instead.The American inventor Thomas Edison was also dyslexic.Dyslexia first was recognized in Europe and the United States more than 80 years ago.Many years passed before doctors discovered that persons with the disorder were not mentally slow or disabled.The doctors found that the brains of persons with dyslexia are different.In most people,the left side of the brain一 the part that controls language is larger than the right side.In persons with dyslexia,the right side of the brain is bigger. Doctors are not sure what causes this difference.However,research has shown that dyslexia is more common in males than in females,and it is found more often in persons who are left handed.No one knows the cause of dyslexia,but some scientists believe that it may result from chemical changes in a baby's body long before it is born.They are trying to find ways to teach persons with dyslexia.
