Bowhead whales (弓头鲸) can live 200 years or longer. How they do it is no longer among the secrets of the deep. Scientists have mapped the genetic code of this long-lived whale species. The international effort found unusual features in the Arctic whale’s genes. Those features likely protect the species against cancer and other problems related to old age.
“We hope to learn what is the secret for living longer, healthier lives,” says João Pedro de Magalhães. He is a gerontologist (a scientist who studies old age) at the University of Liverpool in England. He also is co-author of the study that appeared January 6 in Cell Reports. His team hopes, he says, that its new findings might one day be used “to improve human health and preserve human life.”
No other mammal is known to live as long as the bowhead. Scientists have shown that some of these whales have lived well beyond 100—including one that survived to 211. For perspective, if he were still alive, Abraham Lincoln would be turning just 206 this year. De Magalhães’ team wanted to understand how the bowhead can live so long. To study this, the experts analyzed the animal’s complete set of genetic instructions, called its genome (基因组). Those instructions are coded in the animal’s DNA. The team also compared the whale’s genome to those of people, mice and cows.
The scientists discovered differences, including mutations (突变), in the whale’s genes. Those changes are linked to cancer, aging and cell growth. The results suggest that the whales are better than humans at repairing their DNA. That’s important because damaged or flawed DNA can lead to diseases, including some cancers.
Bowheads also are better at keeping abnormally dividing cells in check. Together, the changes appear to allow bowhead whales to live longer without developing age-related diseases such as cancer, says de Magalhães.
1.What do we learn about bowhead whales?
A.Their average life is 100. B.They are the longest-lived animals.
C.They don’t have aging problems. D.They live in the Arctic Ocean.
2.Why did scientists map the genetic code of bowhead whales?
A.To discover the secret of long life.
B.To find out a cure for cancer.
C.To prevent age-related diseases.
D.To lengthen human life.
3.Why does the author mention Abraham Lincoln?
A.To remind us of the time he lived.
B.To show the long life of the bowhead.
C.To compare him with the bowhead.
D.To express people’s respect for him.
4.What allows the bowhead to live a longer and healthier life?
A.Good DNA repair system. B.Gene mutation.
C.Cell division. D.Perfect living environment.

阅读下面短文，根据小题的具体要求，简要回答问题。
The north magnetic pole(磁极)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(地轴),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(假说)relates it to “magnetic jerks”,sudden shifts(变化)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.”
1.Find in the passage a word closest in meaning to the underlined word “angling”.

2.What could happen to the north magnetic pole by the middle of the 21st century?(回答词数不超过8个)

The World Health Organization says that the disease polio is no longer widespread in India. In 2009，half of the world’s cases of polio were there. But In 2011, there was only one new case of polio in the country.
Polio is caused by a virus. It spreads very quickly from one person to another. Victims often lose the use of their arms and legs. In the most serious cases, polio can kill a person.
Twenty-five years ago, polio affected about 200, 000 children in India each year. The United Nations children’s organization, UNICEF, sent teams. of health workers into local villages. Team members told families in their neighborhood about the importance of giving liquid medicine to children to protect them against polio.
But it was not easy at first. A member said, “They used to think that our children will not be able to have children when they grow up if they get the drop. They used to think like this. But now they don’t. Now they allow their kids to get the drops.” Now things have changed. Asma Khatun is a mother in the town of Ghaziabad in the northern state of Utter Pradesh. She said, “Whenever anyone comes, we get the children vaccinated(接种疫苗). Even if nobody came to our house, we would send our children to a clinic to get vaccinated.
A local Muslim leader says the vaccination campaign has been successful because it is supported by religious leaders. He said, “The polio vaccination campaign has been successful here because our Muslim scholars are with us.
With their support, we are able to make people understand that giving children the vaccine is beneficial and crucial.”
The Indian government has now launched a new campaign to vaccinate 170 million children under the age of five. The campaign will target newborn babies, migrants and people living in poor, crowded areas where the disease spreads more quickly.
1.What is the writer’s purpose in writing the passage?
A. To tell the world how to fight against polio.
B. To tell us good news about fighting against polio in India.
C. To prove that with good methods polio can be prevented.
D. To explain why people in India are no longer afraid of polio.
2.We learn that when parents in India were first advised to get their children vaccinated, they .
A. didn’t believe it could prevent polio
B. became relaxed and believed it would work
C. were afraid it would do harm to their children
D. were afraid it would make their children die
3.What is Muslim leaders’ attitude towards getting children vaccinated now?
A. Supportive.
B. Negative.
C. Uncaring.
D. Worried.
4.We know from the last paragraph that the new campaign .
A. was started by the World Health Organization
B. is successful mainly because of Muslim scholars
C. aims at 170 million children under the age of five
D. mainly targets people living in poor and crowded areas
