Unusual incidents are being reported across the Arctic. Inuit(因纽特人)families going off on snowmobiles to prepare their summer hunting camps have found themselves cut off from home by a sea of mud .There are also reports of sea ice breaking up earlier than usual, carrying seals beyond the reach of hunters. Climate change may still be a rather abstract (抽象的) idea to most of us ,but in the Arctic it is already having great effects –if summertime ice continues to shrink at its present rate ,the Arctic Ocean could soon become almost ice-free in summer .The knock –on effects(连锁反应)are likely to include more warming, cloudier skies ,and higher sea levels .Scientists are increasingly eager to find out what’s going on in the Arctic.
For the Inuit the problem is urgent. They live in unsteady balance with one of the toughest environments on earth. Climate change, whatever its causes, is a direct danger to their way of life. Nobody knows the Arctic as well as the locals, which is why they are not content simply to stand back and let outsider experts tell them what’s happening. In Canada, where the Inuit people are trying hard to guard their hard-won autonomy in the country’s newest land, Nunavut, they believe their best hope of survival in this changing environment lies in combining their ancestral knowledge with the best of modern science. This is challenge in itself.
The Canadian Arctic is a vast , treeless polar desert that’s covered with snow for most of the year. Adventure into this area and you get some idea of the hardships facing anyone who calls this home. Farming is out of the question and nature offers few pickings. Humans first settled in the Arctic a mere 4,500 years ago, surviving by taking advantage of sea fish. The environment tested them to the limits: sometimes the settlers were successful, sometimes they failed and disappeared. But around a thousand years ago, one group appeared that was uniquely well adapted to deal with the Arctic environment. These Thule people moved in from Alaska, bringing dogs, iron tools and the like. They are the ancestors of today’s Inuit people.
1.Which of the following is not likely to be the effect of climate change?
A.Shorter and shorter summertime.
B.Ice-free summer around the Arctic.
C.Higher sea levels.
D.More cloudy skies.
2.The Inuit people believe the solution to the climate change problem is ________.
A.to change their way of life
B.to use their ancestral knowledge
C.to make the best of modem science
D.to use their ancestral knowledge and modern science
3.It can be concluded from the last paragraph that ________.
A.the first settlers in the Arctic survived by taking advantage of sea fish
B.it’s hard to farm in the Arctic due to the climate change
C.the ancestors of Inuit people stood out among the settlers
D.the Thule people from Alaska invented iron tools
4.Which of the following is the best title of this passage?
A.Climate change and the Inuit

The government of Norway is planning to build an unusual storage center on an island in the Arctic Ocean. The place would be large enough to hold about two million seeds. The goal is to present all crops known to scientists. The British magazine New Scientist published details of the plan last month. The structure will be designed to protect the world’s food supply against nuclear war, climate change and other possible threats. It will be built in a mountain on the Norwegian island of Spitsbergen. The mountain is less than one thousand kilometers from the North Pole, the northernmost position on earth.
An international group called the Global Crop Diversity Trust is working on the project. The director of the group, Cary Fowler, spoke to New Scientist. He said the project would let the world rebuild agriculture if, in his word, “the worst came to the worst”. Norway is expected to start work next year. The project is expected to cost three million dollars. Workers will drill(钻孔) deep in the side of a sandstone mountain. Temperatures in the area never rise above 0ºC. The seeds will be protected behind walls a meter thick and high-security door.
The magazine report says the collection will represent the products of ten thousand years of farming. Most of the seeds at first will e from collections at seed banks in Africa, Asia and Latin America. To last a long time, seeds need to be kept in very low temperatures. Workers will not be present all the time. But they plan to replace the air inside the storage space each winter. Winter temperatures on the island are about eighteen degrees below 0ºC. The cold weather would protect the seeds even if the air could not be replaced.
Mr. Fowler says the proposed structure will be the world’s safest gene bank. He says the plant seeds would only be used when all other seeds are gone for some reason. Norway first put forward the idea in the 1980s. But safety concerns delayed the plan. At that time, the Soviet Union was meeting in Rome of the Food and Agriculture Organization.
1.The project is meant to ______.
A.increase the world’s food output in the future
B.carry out some scientific experiments on plant genes
C.build an exhibition centre of the world’s plant seeds
D.protect crop seeds from dying out in case of possible disasters
2.Which of the following statements is TRUE according to the above passage?
A.The government of Norway will perform the project alone.
B.Seeds to be collected there were produced ten thousands years ago.
C.Spitsbergen is chosen because it is free of the nuclear war forever.
D.Temperature is a major consideration when choosing the storage place.
3.We can infer from the text that _______.
A.Norway had meant to build the storage centre about 20 years before.
B.The storage center will greatly promote world agriculture
C.People will get newly-developed seeds from the center every year.
D.There haven’t been any seed storage centres in the world before.
4.What is probably the best title of the passage?
A.The Best Place to Store Seeds
B.Noah’s Ark(诺亚方舟)of Plant Seeds in Plan
C.Concerns of World Food Supply
D.A New Way to Feed the World

Red wolves used to be a common sight across the southeastern United States.But today,there are just 50 left in the wild.
The red wolf is one of the most endangered wild canine species(犬科动物)in the world.In the past five years, the species' population in the wild has dropped by half.The US Fish and Wildlife Service had been working for decades to reintroduce the species into the wild,but the organization recently put the program on hold.
According to Cindy Dohner,the southeast regional director for the Fish and Wildlife Service,the agency is focusing on "our commitment to get the science right and rebuild trust with our neighbors in those communities as we address problems regarding the recovery of the red wolf."But the animal-rights group Defenders of Wildlife said on its website that the decision made by the Fish and Wildlife Service "falls well short of what is needed to continue red wolf recovery."
The red wolf was declared an endangered species in 1967.By 1980,it had been hunted to extinction(灭绝)in the wild.Some hunters thought the red wolves were coyotes(土狼), so most people killed them because they believed wolves were dangerous and would attack people.This wrong belief has made it difficult to restore the species, because people are afraid to have red wolves reintroduced near human communities.
Experts say that one way to fight these fears is simply to teach people about red wolves.In reality,they are shy animals that they don't get close to humans and hunt mostly at night.According to the Fish and Mildlife Service, captive breeding centers in the US are home to about 200 red wolves.But without continued efforts from the government and private groups,red wolves will continue to suffer.
1.The underlined phrase "put...on hold" in Paragraph 2 probably means “ ”.
A. paused B. promoted
C. overlooked D. accomplished
2.What does Defenders of Wildlife think of the Fish and Wildlife Service's decision?
A. Practical. B. Annoying.
C. Satisfactory. D. Disappointing.
3.The trouble in reintroducing red wolves near human communities lies in____.
A. humans' over-hunting
B. fears in human beings
C. shortage of food in the wild
D. lack of governmental support
4.What can we know about red wolves from the text?
A. They don't hunt in the daytime at all.
B. Their total population in the world is only 50.
C. They keep away from humans due to shyness.
D. They are dangerous because they attack people.

Many skilled young people are being forced into part-time and unskilled work, the report says. It warns of a "crisis" with more than six million people so disillusioned they have given up looking for work. The ILO(International Labor Organization)wants governments to make job creation a priority. It wants more training schemes, and also tax breaks for employers.
"The youth unemployment crisis can be beaten but only if job creation for young people becomes a key priority in policymaking and private sector investment picks up significantly," said Jose Manuel Salazar-Xirinachs, executive director of the ILO's employment sector.
Since 2007, the number of young people without jobs has risen by four million - up from less than 12%, the Global Employment Trends for Youth Report says. Almost 13% of people aged between 15 and 24 - or almost 75 million - have no work, although this is slightly down on its peak in 2009.
In the European Union, one in five young people are looking for work, the report claims. Some 27.9% of youths were unemployed in North Africa last year —a rise of five percentage points on 2010. In the Middle East, the figure stood at 26.5% in the report's regional breakdown. Even in East Asia, perhaps the most economically active region, the unemployment rate was 2.8 times higher for young people than for adults, the report said.
But, the ILO report reveals, the true picture of youth unemployment is even more pessimistic. Many young people are extending their time in higher education because they cannot find jobs. Others are taking part-time unskilled work because they cannot find work in the fields they trained for.
The ILO says that more than six million young people worldwide have given up looking for work and are becomingly increasingly detached from society. By not using their skills they are losing them, the report says, and if there is no improvement in the jobs market soon, they may be not only unemployed, but unemployable.
The ILO suggests offering tax breaks to businesses hiring young people and offering more programmes to help kick-start careers.
1.Which of the following is true according to Jose Manuel Salazar-Xirinachs?
A. Since 2007, the number of young people out of job has risen to 4 million.
B. Nearly 13% of the young people have no work.
C. Job creation should be made a key priority in policymaking.
D. The youth unemployment rate can never go down.
2.The various figures in paragraph 3 and 4 were used to show_______.
A. The employment situation is serious only in the European Union
B. The global youth employment situation is depressing
C. East Asia enjoys a high youth employment rate
D. Compared with the situation in 2009, the youth employment in 2007 is slightly better
3.According to ILO, the following are caused by high youth unemployment rate except_______.
A. The government calls on young people to take up whatever job is available
B. Many young people are making their time in higher education longer
C. Some young people are taking part-time unskilled work
D. Many young people have given up looking for work
4.The ILO offered many solutions to the crisis of youth unemployment, including_______.
a. making job creations a priority b. more training schemes
c. encouraging public investment d. tax breaks for employers
e. offering more entrepreneurship programmes to help start careers
A. a b c e B. b c d e C. a c d e D. a b d e
