Far from the land of Antarctica(南极洲), a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.
Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.
The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein(蛋白质) never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules(分子) held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein, or AFGP.

GU Zhaodi, 60, had taken water for granted for years. In fact, no one in the beautiful lake city of Wuxi, Jiangsu Province had bothered to spare a thought on water.
But all that changed dramatically overnight last month when taps in the city ran dry. Due to a blue-green algae(藻类)  outbreak in Taihu Lake, China’s third largest freshwater lake and the source of drinking water for 4 million Wuxi residents(居民),water from the city’s taps became dark and smelly.
“I can’t believe there is no water for drinking, let alone cooking and washing,”said Gu.
The lake was blanketed with the algae, giving off a strong smell of rotting meat. A stone thrown into it took a long time to sink. Experts said that algae usually boom because of hot water and rich chemicals like phosphor(磷)in the water.
“High temperature and a lack of rain in the past few months helped the growth of algae,”said Zhang Lijun, an official from the State Environment Protection Administration. “However, pollution from human activity should be most blamed for the disaster.”
Taihu Lake is surrounded by many small factories, whichsprang up in the 1980s.Inthe 1990s,many foreign-funded(外资的) companies joined in. The industries prospered(繁荣),Wuxi has grown into one of the wealthiest cities in East China.
But that came at the price of pollution. The lake was treated like a waste dump(垃圾堆),with factories emptying industrial waste and untreated sewage(污水)into it.
Although, after the government's effort, life in the city has gone back to normal, the one-week crisis(危机)rang a bell for the government and local people.“It's time to rebuild the beauty of nature, or our lives will be at risk,”said Gu.
“A safe environment comes first. Economic growth will be nothing without fresh water to drink and clean air to breathe.” said China Daily.

The deadly earthquake and tsunami (海啸) that struck Japan on March 11 damaged two nuclear power stations. Officials are now working to prevent dangerous radiation from poisoning the air in the area surrounding the Fukushima Daiichi plant. The Japanese government has ordered people living within 12 and a half miles of the plant to evacuate, and asked those living 12 and a half to 20 miles away to stay indoors.
Nuclear power plants create energy using a chemical reaction that produces large amounts of heat. Reactors(反应堆)in Japan have many long, thin rods, called fuel rods(棒), which must be kept cool.
If the reactor’s fuel rods aren’t cooled, the reaction can burn out of control. That’s what happened at the two Japanese plants after the quake caused a power failure and the cooling systems malfunctioned(发生故障). This overheating could cause radiation to escape and sicken many people.
Japan’s 54 nuclear reactors are built to withstand the many small or moderate earthquakes the country faces each year. But Friday’s earthquake was one of the most severe earthquakes ever recorded.
People exposed to unsafe levels of radiation have a higher than normal risk of getting cancer. The Japanese government has been distributing potassium iodide(碘化钾)pills to people in the surrounding areas to protect those who may have come in contact with radiation from the power plant. The pills flood the body with healthy potassium iodide. The potassium iodide works to crowd out “bad” iodine in the body that may have been poisoned by radiation.
On Tuesday morning, 750 workers left the Fukushima Daiichi plant. However, 50 workers stayed behind to use sweater to cool the fuel rods. These dedicated employees are risking their own lives to save many others.
On Thursday, officials used helicopters, fire trucks, and water cannons to spray water on the reactors to cool the fuel rods. But it’s not clear whether these efforts were successful. Officials are now working on a power line to restore electricity to the plant. They hope this will help restart the plant’s cooling system and stop the fuel rods from leaking radiation.
【小题1】The underlined word “evacuate” in Paragraph 1 probably means            .

A.helpB.restC.stopD.leave
【小题2】What can we learn from the text?
A.The local people are scared and ready to run away.
B.The earthquake led to many deaths and caused damage to roads.
C.The Japanese government has found a kind of pill that can treat cancer.
D.The two stations were damaged because their cooling systems didn’t work.
【小题3】In the last paragraph, the author mainly states            .
A.lack of help
B.international aids
C.the government’s efforts
D.the result of the disaster
【小题4】This text is most probably taken from            .

The pound new Library of Birmingham(LoB)will be the most visible sign of the way the city is accepting the digitalization(数字化)of everyday life.

Set to open in 2013, the £188m LoB is already beginning to tale shape next to the Birmingham Repertory Theatre, with which it will share some equipment.[来源:Z。xx。k.Com]

As digital media(媒介)is important to its idea. the project is already providing chances for some of the many small new local companies working at the new technologies.

Brian Gambles, the LoB project director, says it is about giving people the right tools for learning,“The aim is to mix the physical with the digital. Providing 24-hour services which can be used through many different ways. It is important to enable us to reach more people, more effectively.”

The digital library will, he says, be as important as the physical one, allowing the distant use of the services, making sure that it is never closed to the public.

Even before the LoB is complete, the public has been able to go online to visit the Virtual(虚拟的)LoB, designed by Baden, the Birmingham virtual worlds specialists. Not only have the public been able to learn about LoB, but the virtual one has also enabled those working on the LoB to understand the building and how it will work before it even opens.

Two other small Birmingham-based digital companies are working on the LoB projects. Substrat, a digital design company, is developing what it calls “enlarge reality” project. It is about the use of an exciting smart phone, an important part of the LoB which is in the early stages of development is an online library of figures of the city being built by a digital content company in Cahoots, in which users will be encouraged to add to and comment on the material.

    Gambles says: “Technology will enable us to make the library’s content and services open to citizens as sever before.”
