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.
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 |

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. |
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. |
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 |
I was born in New York, but I grew up in San Francisco. I began to live in London 25 years ago. If I am asked now where I want to live forever, I would say London. But I will always be American.
San Francisco, like London, has many parks. Every day my sisters and I were taken to play in the parks as children. I didn't go to school. I only had three hours of formal education when I was five. I was sent to school in the morning but came home at noon on the first day. I said I didn't enjoy it and hadn't learned anything. My parents thought that school was unsuitable for me. They agreed with me, so I never went back to school.
Then my mother taught me and my two sisters at home, in the way of an English lady who had good education. We learned languages and reading more than sciences and maths. Sometimes she taught us herself, but we also had other teachers. They asked us to take lessons every day. About once a week we walked to Golden Gate Park. While we were walking, my mother taught me to read music. One day I noticed a little toy train in the window of a shop and I remember now how I'd like to have it. I couldn't say "r" when I was small. My mother said if I could say an "r" well, I would have the toy train. I practiced and practiced. Then one morning I woke everybody up with my "r"s. I got the toy train. I usually get the things I want in life — but I work hard for them.The writer ___ .

President Obama,s plan last week to overhaul(改善)former president George W.Bush’s No Child left Behind program is an improvement on a good thin9.But it doesn’t go far enough.
Obama outlined a goal that by 2020,all grade school and high school students ale on a path toward college and career readiness.
However, what we need is a practical plan that not only requires all high school graduates to take at least two years of college but also makes it financially possible for them to do so. We’ve provided a free public education through the l2th grade.If we’re going to keep up—or catch up—with some other countries(1ike China)in preparing young people for careers,a 12-year education program no longer is enough.
About 3 million students across the USA will graduate from high school this spring. But only 2 million will go on to college, according to a survey by the National Center for Education Statistics(NCFES).For the more than l million who won’t go on,money is a major factor.If tuition(学费)were free,about half of them could make up other COSTS from family or part—time jobs.
Critics(批评家)of free college tuition will say we can’t afford it because of the federal deficit(联邦赤字)and other rising costs.Let’s see some government spending in detail:
In the last nearly 10 years.the wars in Iraq and Afghanistan have cost us $1 trillion(that’s $1,000 billion,or an average of$100 billion a year).Federal money spent on public elementary and secondary education in
the last year for which figures are available was$47 billion.If we end costly and unnecessary wars and nation—building efforts abroad,the federal government could provide more money on public education,for which state and local governments now carry most of the burden(负担).
According to President Obama’s plan,in 10 years,.
A.there will be no expensive and unnecessary Wars |
B.all grade and high school students can go to college |
C.the U.S.will catch up with China in career preparation |
D.students Call enjoy a l2-year public free education |
If tuition were not charged.
A.about 2.5 million students could afford college education |
B.about 2 million students could be provided chances of college education |
C.over l million students still could not afford college education |
D.about 3 million students could graduate from high school |
The author may agree that President Obama’s plan
A.has little to do with Gorge W.Bush’s program |
B.does not agree with the survey by NCFES |
C.does not contain practical measures to achieve its goal |
D.will lighten the burden of state and local governments |
It can be inferred from the passage that
A.the wars in Iraq and Afghanistan are expensive but necessary
B.the federal Can not provide more money on education
C,critics of free college tuition think little of the plan
D.President Obama’s plan might be hard to carry out
Things similar continuously happened in Haiti and Chile.Thousands of people were
buried in the earthquake and lost their fives.What if we could have warned them? People are always trying hard to find a way of preventing building collapsing(坍塌).Better materials and technology help,but are not a solution.Just like humans,a building has its own life circle from “birth” to “death”.If we know when a building is going to collapse,we can repair it in advance or get out before it falls.
Now, scientists at the University of Illinois have developed a material that turns red before it breaks.The invention could be used in things like climbing ropes,or bridge supports.The secret behind the color-changing material is a type of molecule(分子).A molecule is a group of atoms held together by chemical bonds(化学键).Imagine you and your friends standing in a circle,holding hands.Each person stands for one atom,your hands represent the bonds,and the entire circle represents a molecule.If one person lets go of his or her hands,the molecule changes color.The research team put the molecule into a soft material.When the researchers stretched(拉长) the material:it turned bright red a few seconds before it broke into two pieces.
When they repeatedly stretched and relaxed the material,without breaking it,it only turned a little red.
The major problem is,light can get rid of the red color.When the team shone a bright light on the molecule,the broken bond was fixed,and the color disappeared.If bright fight keeps the red color from appearing,the material’s warning system will be useless.Scientists still have a lot of work to do before the color-changing molecule can be used outside the lab. The passage mainly about
A.a way of preventing building from breaking down |
B.a series of earthquakes in Haiti and Chile |
C.a way of warning before buildings collapse |
D.a newly-discovered structure of a molecule |
According to the passage,we can conclude that
A.there are problems to solve before putting the new material to use |
B.scientists have found the life circle of buildings from “birth” to “death” |
C.bright fight makes the red color visible to human eyes |
D.the new material is unlikely to be used in building bridges |
The color-changing molecule can
A.make building materials much stronger |
B.help building materials get stretched if necessary |
C.prevent the earthquake from killing people |
D.remind people to leave buildings before they fall |
The warning system is based on the fact that
A.red color won’t show up when it meets bright fight |
B.a material with a certain type of molecule Can turn red when stretched etched |
C.a building has its own life circle of “birth” to “death” |
D.the broken bond will fix itself when a molecule meets bright fight |
BEIJING — The rescue operations at a coal mine accident have ended with 105 miners dead.The State Council has organized an investigation team to probe (调查) into what caused the disaster in the city of Linfen, North China’s Shanxi Province.Preliminary investigations show the illegal mining of an unauthorized seam, and the number of miners who had been sent down the shaft far exceeded its capacity.
This mine was found to have long disregarded the rules to steal state coal, and did not have a list of miners employed to check the number of miners missing after the accident.
How did such a coal mine get all the necessary licenses for production? How did it pass the three safety inspections the local government organized last month?
In response to this disaster, the Shanxi governor promised to set up hotlines for people to report illegal coal mines and rewards as high as 100,000 yuan for tip-offs.
We appreciate the action this governor has taken to solving the coal mining problems, and we believe that the reporting scheme will help to stop the existence of illegal coal mines.
But at the same time we have reason to question how governments at various levels supervise these mines.
The sad fact that such a mine with serious safety problems could pass three consecutive local government safety inspections in a month is enough to tell us how ineffective the safety inspections were.
What if these inspections were just a formality? What if the inspectors were bribed by the mine owners to turn a blind eye to the safety dangers? We can well imagine what would happen if reports about mine problems were handled by such officials.
So a thorough probe must find out who are responsible for the death of so many miners.A real safety inspection and management system must be established to guarantee that safety dangers will be removed.What is NOT one of the causes of this coal mine accident?
A.The workers didn’t operate properly. |
B.The mine didn’t obey the rules to mine for coal. |
C.A lot more miners than allowed were working under the mine. |
D.The safety inspections were ineffective. |
According to the writer, who should be further investigated?
A.Mine owners and miners. |
B.Miners’ families and mine staff. |
C.Government officials and safety inspectors. |
D.The Shanxi governor and miners. |
What can we infer from the passage?
A.More than 105 miners died in the disaster. |
B.Some other coal mines like this one exist in Shanxi province. |
C.Safety inspectors just turned a blind eye to hidden dangers. |
D.The three inspections were only a formality. |
What does the underlined word “tip-offs” probably mean in Paragraph 4?
A.Some warnings. |
B.Some money for one’s service. |
C.Some secret information. |
D.Some pieces of advice. |
