The north magnetic pole(磁極)is no longer a resident of Canada.It has drifted across the Canadian Arctic and is now angling toward Siberia.
Not to be confused with the geographic North Pole—the northern extremity of the Earth’s axis(地軸),the north magnetic pole(where the Earth’s magnetic field is directed downward)is moving due to natural changes in the Earth’s magnetic field,a process that originates about 3000 kilometers below our feet,in the outer core(核心)of the planet.But scientists are now noticing that the magnetic pole has picked up its pace.

Over the past century,the pole has been migrating at an average speed of about 10 kilometers per year,says Larry Newitt,head of Geomagnetic Laboratory at Natural Resources Canada in Ottawa.Since the 1970s,this speed has increased to about 50 kilometers per year.
Scientists are wondering why the speed is increasing,says Newitt.One hypothesis(假說(shuō))relates it to “magnetic jerks”,sudden shifts(變化)in the rate of change of the magnetic field.There have been three jerks in the past four decades,each one correlating to an increases in speed.
If the north magnetic pole continues at its current rate,it could reach Siberia by 2056.
“For most of recorded history,the pole has been a part of Canada,and now it’s not,”says Newitt.“It may be a blow to our collective psyche,but other than that,it doesn’t have a major effect on most people’s existence.”
73.Find in the passage a word closest in meaning to the underlined word “angling”.

When a storm is coming, most people leave the area as quickly ad possible and head for safety. But there are a few people who will get into their cars and go straight for the center of the storm. These people are willing to risk(冒…危險(xiǎn))being killed by floods or 100-kilometer-an-hour winds for the excitement of watching the storm close up.
“Storm chasing(追逐)” is becoming an increasingly popular hobby(喜好), especially in the Midwest of the United States, where there are frequent storms between March and July. A storm chaser begins the day by checking the Internet for the latest weather reports, and then drives up to 1,000 kilometers to where the storm will be and waits for it to develop.
Although anyone can do it , storm chasing is extremely dangerous. The power of a big storm can throw a cow into the air or destroy a whole house in seconds. Storm chasers are also often hurt in accidents caused by driving in a heavy rain. If you are a beginner, it is much safer to join a group for storm-chasing vacations during the storm season.
Even then, storm chasing is not all adventure and excitement . “Storm chasing is 95% driving,” says Daniel Lynch, who spends most of his summer storm-chasing.    “Sometimes you can sit around for hours waiting for something to happen, and all you get is blue sky and a few light showers.”
However, for storm chasers, it is all worth it. “When you get close to a storm, it is the most exciting sight you will ever see in your life,” says Jasper Morley. “Every storm is an example of the power of nature, It is the greatest show on Earth.”
56. For storm chasing, the first thing storm chasers do is to          .
A. head straight for the center of the storm  B. get into the car for safety
C. wait patiently for the storm to develop    D. collect information about a coming storm
57. Beginners of storm chasing are advised             .
A. not to drive in a heavy rain                           B. to do it in an organized way
C. not to get too close to a storm                 D. to spend more time on it in summer
58. By saying “it is all worth it” in the last paragraph, the author means that             .
A. storm chasing costs a lot of money          B. storm chasing is worth hours of waiting
C. efforts in storm chasing are well paid         D. a storm presents the greatest show on Earth
59. What can we learn from the text?
A.  Sometimes storm chasers get nothing but disappointment
B.  Many storm chasers get killed in the storms.
C. Storm chasing is becoming popular around the world.
D. Storm chasing is only fit for young people.

Shishmaref, an Eskimo village on an island off northwestern Alaska, is falling into the ocean. Giant storm waves have so hit the place—once well buffered by sea ice—that villagers voted in 2002 to leave their ancestral home for the mainland. They are being called one of the first refugees（難民）of global warming.  
“We tend to describe climate change in terms that are abstract—a one degree rise in temperature, an increase in greenhouse gases—but when waves wash away a village, that’s concrete and very emotional,” says Igor Krupnik, an expert at the National Museum of Natural History. “When they lose a piece of their land, they aren’t just losing a certain number of square miles. They are losing part of their history and their memory. They are losing childhood events and grandparents’ tales.”
Before temperatures began to rise in Shishmaref about 30 years ago, 20 to 30 miles of hard sea ice protected the village from powerful fall storms. But the natives say the ice doesn’t freeze as solidly or as soon as it used to and now stretches only six or seven miles, leaving the community of 600 people more exposed. Storms have swept houses into the ocean.
The villagers’ plan is to move to Tin Creek, a site on the Alaska mainland 12 miles away, and they have received $180 million from the government. Residents hope that in their new community they’ll be able to maintain their close ties, continue hunting animals, and keep fishing, much as their ancestors have done for centuries. “People are asking why the government should be spending so much money on so few people,” said a government official. “But people in Alaska are like everyone else. We want to help keep their culture alive.”
小題1:The underlined word “buffered” probably means “______”.  
A．protectedB．destroyedC．preventedD．damaged
小題2:From the passage what do we know about the sea ice around the village in the past?
A．It was very thin and easily broken.
B．It was very thick and smooth.
C．It frozen more solidly and sooner.
D．It frozen more slowly and solidly.
小題3:According to the passage, _____ caused the village to be in danger of disappearing.
A．water pollutionB．global warming
C．a(chǎn)ir pollutionD．human’s actions
小題4:What’s the villagers’ main purpose to rebuild the community?
A．To live more happilyB．To earn money
C．To avoid being washed awayD．To keep their culture alive

A small town in southwest Britain is banning(禁止) plastic bags in an attempt to help the environment and cut waste—a step that environmentalists believe is a first for Europe.
Shopkeepers in Modbury population 1500,agreed to stop handing out disposable plastic bags to customers on Saturday.They said paper sacks and cloth carrier bags would be offered instead.
Last month,San Franciso became the first U.S. city to ban plastic grocery bags.Internationally,laws to discourage the use of plastic bags have been passed in parts of South Africa and Ireland,where governments either tax shoppers who use them or fine companies that hand them out.Bangladesh already bans them,and so do at least 30 remote Alaskan villages.
Modbury,about 225 miles southwest of London,has also declared a bag amnesty(寬限期),allowing local people to hand in plastic bags that have piled up at home.They will be sent for traveling.
The Modbury ban was the idea of Rebecca Hosking,who saw the effect of bags on marine life while working in the Pacific as a wildlife camerawoman.She said response(反應(yīng)) in the town so far had been “really positive”.
“Modbury is quite an old-fashioned town and a lot of people have wicker baskets to go out shopping anyway,”Hosking told Sky News Television.
The Worldwatch Institute,an environmental research agency,states that 100 billion plastic bags are thrown away each year in the United States alone.More than 500 billion are used yearly around the world.
小題1:What was Rebecca Hosking?
A．A lawyer.B．An environmentalist.
C．A sailor.D．A photographer.

A．most of the people in Modbury continue to use plastic bags
B．fewer and fewer plastic bags will be used in the world
C．San Francisco is the first city to ban plastic bags in the world
D．most countries in the world have passed laws to ban plastic bags

下面是幾則寓言小故事：
小題1:An ant went to the bank of a river to quench its thirst, and being carried away by the rush of the stream, was on the point of drowning. A dove sitting on a tree overhanging the water plucked a leaf and let it fall into the stream close to her. The ant climbed onto it and floated in safety to the bank. Shortly afterwards a birdcatcher came and stood under the tree, aiming at the dove. The ant, perceiving his design, stung him in the foot. In pain the birdcatcher shouted, and the noise made the dove take wing.
小題2:Two men were travelling together, when a bear suddenly met them on their path. One of them climbed up quickly into a tree and hid himself in the branches. The other, seeing that he must be attacked, fell flat on the ground, and when the bear came up and felt him with his snout, and smelt him all over, he held his breath, and pretended to be dead as much as he could. The bear soon left him, for he will not touch a dead body. When he disappeared, the other traveller descended from the tree, and asked his friend what it was the bear had whispered in his ear. “He gave me this advice,” his companion replied. “Never travel with a friend who deserts you at the approach of danger.”
小題3:A prince had some monkeys trained to dance. Being naturally good at learning, they showed themselves excellent pupils, and in their rich clothes and masks, they danced as well as any of the courtiers. Their performance was often repeated with great applause, till on one occasion a courtier, bent on mischief, took from his pocket a handful of nuts and threw them upon the stage. The monkeys at the sight of the nuts forgot their dancing and became (as indeed they were) monkeys instead of actors. Pulling off their masks and tearing their robes, they fought with one another for the nuts. The dancing spectacle thus came to an end in the laughter and ridicule of the audience.
小題4:A cock was once strutting up and down the farmyard among the hens when suddenly he noticed something shining in the straw. "Ho! ho!" said he, "that’s for me," and soon rooted it out from beneath the straw. It turned out to be a pearl that by some chance had been lost in the yard. “You may be a treasure,” signed the cock, “to man, but for me I would rather have a single barley-corn.”
小題5:An old man on the point of death summoned his sons around him to give them some parting advice. He ordered his servants to bring in a bunch of sticks, and said to his eldest son: "Break it." The son tried hard, but with all his efforts was unable to break the bundle. The other sons also tried, but none of them was successful. “Untie it,” said the father, “and each of you take a stick.” When they had done so, he called out to them: “Now, break,” and each stick was easily broken.

A．Not everything you see is what it appears to be.
B．One man’s pleasure may be another’s pain. / One man’s meat is another’s poison,

How Room Designs Affect Our Work and Feelings
Architects have long had the feeling that the places we live in can affect our thoughts, feelings and behaviors. But now scientists are giving this feeling an empirical（經(jīng)驗(yàn)的，實(shí)證的） basis. They are discovering how to design spaces that promote creativity, keep people focused and lead to relaxation.
Researches show that aspects of the physical environment can influence creativity. In 2007, Joan Meyers-Levy at the University of Minnesota, reported that the height of a room's ceiling affects how people think. Her research indicates that higher ceilings encourage people to think more freely, which may lead them to make more abstract connections. Low ceilings, on the other hand, may inspire a more detailed outlook.
In additions to ceiling height, the view afforded by a building may influence an occupant's ability to concentrate. Nancy Wells and her colleagues at Cornell University found in their study that kids who experienced the greatest increase in greenness as a result of a family move made the most gains on a standard test of attention.
Using nature to improve focus of attention ought to pay off  academically, and it seems to, according to a study led by C. Kenneth Tanner, head of the School Design & Planning Laboratory at the University of Georgia. Tanner and his team found that students in classrooms with unblocked views of at least 50 feet outside the window had higher scores on tests of vocabulary, language arts and maths than did students whose classrooms primarily overlooked roads and parking lots.
Recent study on room lighting design suggests than dim（暗淡的） light helps people to loosen up. If that is true generally, keeping the light low during dinner or at parties could increase relaxation. Researchers of Harvard Medical School also discovered that furniture with rounded edges could help visitors relax.
So far scientists have focused mainly on public buildings. "We have a very limited number of studies, so we're almost looking at the problem through a straw（吸管）," architect David Allison says. "How do you take answers to very specific questions and make broad, generalized use of them? That's what we're all struggling with."
小題1:What does Joan Meyers-Levy focus on in her research?
A．Light.B．Ceilings.C．Windows.D．Furniture.
小題2:The passage tells us that ______.
A．the shape of furniture may affect people's feelings
B．lower ceilings may help improve students' creativity
C．children in a dim classroom may improve their grades
D．students in rooms with unblocked views may feel relaxed
小題3:The underlined sentence in the last paragraph probably means that ______.
A．the problem is not approached step by step
B．the researches so far have faults in themselves
C．the problem is too difficult for researchers to detect
D．research in this area is not enough to make generalized patterns
小題4:Which of the following shows the organization of the passage?
CP: Central Point    P: Point   SP: Sub-point（次要點(diǎn)）   C: Conclusion

Life on land probably began about 430 million years ago, though it has existed in the water for perhaps as much as 3,000 million years. When we think of the first thing on land, we probably think of strange animals coming out of the oceans, but in fact no animals could have been living if plants had not been on land first. Plants had to be on land before animals arrived. They supplied the first land animals with the surrounding and food necessity, since they, the plants, are the only form of life that is able to get and store energy.
　　The first plants to exist out of the water were probably certain kinds of algae（海藻）which were followed by other plants that grew close to the ground and needed water in which to reproduce. Once the move to land had been made, however, evolution（進(jìn)化）took place quickly. By the end of 100 million years, plants had developed their roots（根）,and some had got tree -like forms since height was very important in gaining sunlight. About 300 million years ago, much of the world was covered with forests of huge trees. In most ways they were like modern trees. They had roots, leaves, wood, but mostly they had not developed seeds.
　小題1:The main idea of the first paragraph is ________.
A．life on land probably began 430 years ago
B．the first animal on land came from oceans
C．there wouldn't be animals without plants
D．plants are the only form of life that is able to get and store energy
　小題2:Which of the following statements is true according to the passage?
A．Algae has existed for more than 430 million years.
B．It is impossible that algae might be the earliest plant on land.
C．Plants get food from animals in the oceans.
D．Evolution began after animals appeared on land.
　小題3:Plants with roots appeared about ________ million years ago.
A．430B．300C．330D．100
　小題4:According to the passage, ________ appeared earlier than ________.
A．a(chǎn)pples; orangesB．oranges; apples
C．oranges; rosesD．a(chǎn)lgae; wheat
