Most people would agree that it would be wonderful if humans could regenerate (再生) limbs. Those who have lost their arms or legs would be complete again. The day is still far off when this might happen. But in the last 10 years, doctors have reported regeneration in smaller parts of the body, most often fingers.
Regeneration is not a newly-discovered process. For centuries, scientists have seen it work in some kinds of animals. Scientists now are looking for a way to turn on this exciting ability in more highly-developed animals, including humans. Their experiments show that nerves (神经), cell chemistry and the natural electric currents in the body all seem to have a part in this process.
The body of every animal contains general purpose cells that change into whatever kind of cells the body needs. These cells collect around the wound. They form a mass called a blastema (芽基). The cells of the blastema begin to change. Some became bone cells, some muscle cells, some skin cells. Slowly, a new part re-grows from the body outward. When completed, the new part is just like the old one.
More than 200 years ago, Italian scientist Luigi Spallanzani showed that younger animals have a greater ability to regenerate lost parts than older animals. So do animals lower on the ladder of evolutionary (进化的) development. The major differences seem to be that less-developed animals have more nerves in their tails and legs than humans do in their arms and legs.
Another helpful piece of information was discovered in the late 1800s. Scientists found that when a creature is injured, an electrical current flows around the wound. The strength of the current depends on how severe the wound is and on how much nerve tissue (组织) is present.

The largest earthquake （magnitude 里氏 9．5） of the 20th century happened on May 22,1960 off the coast of South Central Chile．
It generated（生成） one of the most destructive Pacific-wide tsunamis（海啸）．Near the generating area, both the earthquake and the tsunami were very much destructive, particularly in the coastal area from Concepcion to the south end of Isia Chiloe．The largest tsunami damage occurred at Isia Chiloe—the coastal area closest to the epicenter（震中）．Huge tsunami waves measuring as high as 25 meters arrived within 10 to 15 minutes after the earthquake, killing at least two hundred people, sinking all the boats, and flooding half a kilometer inland．
There was large damage and loss of life at Concepcion, Chile's top industrial city．Near the city of Valdivia, the earthquake and following aftershocks generated landslides which killed 18 people．At me port city of Valparaiso, a city of 200,000, many buildings collapsed．A total of 130,000 houses were destroyed —one in every three in the earthquake zone and nearly 2,000,000 people were left homeless．
Total damage losses, including to agriculture and to industry, were estimated to be over a half billion dollars ．The total number of death related with both the tsunami and the earthquake was never found accurately for the region Estimates of deaths reached between 490 to 5,7002 with no distinction（差别） as to how many deaths were caused by the earthquake and how many were caused by the tsunami．However, it is believed that most of the deaths in Chile were caused by the tsunami．
68．Where did the largest tsunami damage occurred?
A．Concepcion B．Isia Chiloe C．Valdivia D．Valparaiso
69．What can we learn about the tsunami waves generated by the earthquake?
A．The tsunami waves as high as 25 meters arrived immediately after the earthquake．
B．The tsunami waves killed 200 people and sank all boats．
C．The tsunami waves were very destructive．
D．The tsunami waves flooded half of the inland．
70．What is generally thought the main cause of deaths in Chiloe?
A．landslides B．the tsunami
C．aftershocksD．the magnitude 9．5 earthquake
71．What does the underlined word "collapsed" probably mean ?
A．was destroyedB．caught fire
C．was flooded D．sank
Susan Sontag（1933—2004） was one of the most noticeable figures in the world of literature. For more than 40 years she made it morally necessary to know everything—to read every book worth reading, to see every movie worth seeing. When she was still in her early 30s，publishing essays in such important magazines as Partisan Review，she appeared as the symbol of American culture life，trying hard to follow every new development in literature，film and art. With great effort and serious judgment，Sontag walked at the latest edges of world culture.
Seriousness was one of Sontag’s lifelong watchwords（格言），but at a time when the barriers between the well-educated and the poor-educated were obvious, she argued for a true openness to the pleasure of pop culture. In “Notes Camp”, the 1964 essay that first made her name，she explained what was then a little—known set of difficult understandings，through which she could not have been more famous.“Notes on Camp”，she wrote，represents “a victory of ‘form’ over ‘content’, ‘beauty’ over ‘morals’ ”.
By conviction（信念）she was a sensualist（感觉论者），but by nature she was a moralist（伦理学者），and in the works she published in the 1970s and 1980s，it was the latter side of her that came forward. In “Illness as Metaphor”—published in 1978，after she suffered cancer—she argued against the idea that cancer was somehow a special problem of repressed personalities（被压抑的性格），a concept that effectively blamed the victim for the disease. In fact，re-examining old positions was her lifelong habit.
In America，her story of a 19th century Polish actress who set up a perfect society in California，won the National Book Award in 2000. But it was as a tireless，all-purpose cultural view that she made her lasting fame.
“Sometimes,” she once said，“I feel that，in the end，all I am really defending…is the idea of seriousness，of true seriousness.”And in the end，she made us take it seriously too.

B．she was more a sensualist than a moralist
C．she believed repressed personalities mainly led to illness
D．she would like to re-examine old positions

请阅读下列短文，从每题所给的四个选项（A、B、C、D）中，选出最佳答案，并在答题卡上将该选项的标号涂黑。
After my husband died suddenly from a heart attack，my world crashed around me. My six children were all under 10，and I was burdened with the responsibilities of earning a living，and caring for the children. I was fortunate to find a wonderful housekeeper to care for the children during the week，but from Friday nights to Monday mornings，the children and I were alone.
One Friday evening I came home from work to find a big pretty German Shepherd（牧羊犬）on our doorstep. This dog seemed to intend to enter the house. The children liked “German” immediately and begged me to let him in. I agreed to let him sleep in the basement. That night I slept peacefully for the first time in many weeks.
The following morning we made phone calls and checked lost-and-found ads for German’s owner，but with no results.
On Sunday I had planned to take the children on a picnic. Since I thought it best to leave German behind in case his owner came by，we drove off without him. When we stopped to get gas，we were amazed to see German racing to the gas station after us. No way was he going to be left behind.
Monday morning I let him out for a run. He didn’t come back and we were all disappointed. We were convinced that we would never see him again. We were wrong. The next Friday evening，German was back on our doorstep. Again he stayed until Monday morning，when our housekeeper arrived.
This pattern repeated itself every weekend for almost 10 months. We grew more and more fond of German. We took comfort in his strong，warm presence，and we felt safe with him near us. As German became part of the family，he considered it his duty to check every bedroom to be sure each child was cozy in bed.
Each week，between German’s visits，I grew a little stronger，a little braver and more able to handle; every weekend we were no longer alone and enjoyed his company. Then one Monday morning we patted him on the head and let him out for what turned out to be the last time. We never saw German again.

Will you get a good job？ What will you do？ Many new graduates feel lost when they consider the endless list of career choices. They’ve invested a lot of money for their diploma（文凭）and now an important question stares them in the fact.
I’ve seen so many now graduates who do not know how to use the degree they have just earned. An example was Dave，who loved sports and had played baseball throughout his college years. He had his heart set on working for Nike. But he had never made clear in his own mind what kind of job he could do for Nike，so nothing ever happened. Another example was Allison，who was a history major. She wanted to work as an event planner，but unfortunately，no one hired her. Why？ No experience.
Failing to do some solid career exploration first，to get a clear idea of the types of jobs you can do，is a big error that many college students make. After our suggestion，Dave and Allison both found their jobs. To ensure a brighter future，follow these effective strategies：
—Make educated career choices. Identify the job you want. Conduct research. Ask parents to advise you on actual job duties. Consider what your natural talents are，and look for positions where you can use them.
—Don’t rely on the Internet. Networking is an effective tool—be sure it’s a job—hunting strategy you use. New studies from the Department of Labor state that only 4％ of job-seekers found their job on the Internet. The fact is that 63％ of all jobs are filled by contacts.
Employers are making quick decisions. Most people lose the job in the first minute of the interview. It’s deadly to let the employers focus quickly on how well you can perform the job.
—Practice your interviewing skills. Be ready for the tough questions by first writing out good answers to possible questions and having a role-playing interview with your friend.
60．What does the author seem to be most probable？
A．A job-hunter. B．A magazine editor.
C．A website owner. D．A job-seeking adviser.
61．In order to be well prepared for the interview, you’d better ____________.
A．surf the Internet for contacts
B．get along well with your workmates
C．practice the interview for several times
D．take care of your dress
62．According to the text it is suggested that Dave should ____________.
A．let others know what he can do for them
B．study further to get a higher degree
C．give up his interest in playing basketball
D．take part-time jobs first
63．For Allison, she should ____________.
A．find a job in another field
B．find some work to gain work experience
C．not tell the employer her major
D．offer more personal information
Dear Economist,
My newly-wedded wife and I are deeply in love. There is, however, one issue that threatens the happiness of our marriage. I absolutely insist on shopping at Walmart. My wife, meanwhile, would rather avoid Walmart at all costs.
I have recently tried to convince her that not only does Walmart offer the lowest prices known to man, but that the chain is also a force for good―lower prices mean better standards of living for all consumers, increased global trade means a tighter-knit(紧密团结的) international community, and efficient operations translate into higher productivity growth for the economy. My wife complains about poor labour policies, the “fact” that Walmart squeezes suppliers, and that it puts local shops out of business.
Who is right? Will our marriage survive?
Brian Gee
Dear Brian,
I have to agree with you about Walmart. Jason Furman, then an economist at New York University, now an adviser to President Obama, famously argued in 2005 that Walmart was unwittingly (不知不觉地) a progressive success story. The chain’s prices don’t much affect me (I prefer Whole Foods) but Furman estimated that they benefited low-and-middle-income Americans to the sum of around $250 billion a year.
Walmart does not pay much, so it may depress wages. Then again, it may increase wages by offering jobs to the otherwise-unemployed. Either way, the benefits of low prices to Walmart shoppers far outweigh any seemingly reasonable costs to Walmart employees. And while it is true that Walmart employees tend to be poor, the same is true of Walmart shoppers.
Armed with this information you can face your wife with confidence. You are sure to win the conversation. The divorce is likely to be more argued.
