Surgeons in Spain have successfully carried out the world’s first organ transplant using new stem cell technology. Some people are calling it the greatest medical breakthrough so far this century.
But what are stem cells? As we know, most cells in our bodies are designed to serve specific purposes – for example, a liver cell develops to work in the liver and cannot become a heart cell. But stem cells are different. They are very young, and in the laboratory scientists can grow them into different types of cell.
Claudia Castillo needed a new windpipe after getting a serious disease. Scientists from the University of Bristol in the UK took a donor windpipe, or trachea, from someone who had recently died. They used strong chemicals to remove the donor’s cells, leaving a tissue scaffold(组织支架). This was refilled with cells from Ms Castillo’s windpipe, and stem cells from her bone. After four days the cells had grown sufficiently for the windpipe to be transplanted into Ms Castillo.
Currently, transplant patients have to take drugs for the rest of their lives to prevent their bodies rejecting the new organs. These drugs can have bad side-effects, and do not always prevent rejection. But by using Ms Castillo’s own cells, doctors were able to trick her body into thinking the new windpipe was her own organ. Five months on, Claudia Castillo is in perfect health.
This ground-breaking procedure could be used in other transplant operations in the future. Scientists also believe stem cells might be used to treat Parkinson's disease, Alzheimer's disease, heart disease, stroke, arthritis, diabetes, burns and so on.
However, stem cell research is extremely controversial. The most effective stem cells do not come from adults but from embryos created in laboratories and which are just a few days old. Many people have religious or ethical objections to growing embryos, even if they can be used to cure diseases.

A
Ammie Reddick from East Kilbride, Lanarkshire, was only 18 months old when she had the accident that has scarred her for life. While her mother was away for a moment, the inquisitive baby reached up to a hot kettle in the family kitchen and poured boiling water all over her tiny body.
An ambulance was called and rushed the baby to a nearby hospital. Twenty percent of Ammie's body had been burned and all of her burns were third-degree. The doctors could tell immediately that Ammie's best chance of survival was a specialized burns unit(科) some miles away at Glasgow Royal Infirmary. There, using tissue taken from unburned areas of Ammie's body, surgeons performed complex skin grafts（移植）to close her wounds and control her injuries, an operation that took about six hours. Over the next 16 years, Ammie had 12 more operations to repair her body.
When she started school at Maxwelton Primary at age four, other pupils made cruel comments or simply wouldn't play with her. “I was the only burned child in the street, the class and the school,”she recalls. “Some children refused to become friends because of that.”
Today, age 17, Ammie can only ever remember being a burned person with scars; pain is a permanent part of her body. She still has to have two further operations. Yet she is a confident, outgoing teenager who offers inspiration and hope to other young burns victims.
Ammie's parents Ruby, a funeral director and Gibby, a policeman, have been a great support. “They told me if people had a problem with my burns, the problem was theirs not mine,” says Ammie. “They taught me to cope with other people's reactions and constantly reminded me I was valued and loved." Ammie's positive philosophy（人生观） means she is now in demand with burns organizations, helping younger patients build their self-esteem to live with permanent scars.
“Now she is a member of the Scottish Burned Children's Club, which a charity set up last year.” says Donald Todd, chairman of the club and a senior burns nurse at Edinburgh's Royal Hospital for Sick Children, “Ammie provides so much encouragement for younger ones. She is upbeat and outgoing and a perfect role model for them.”
This month, Ammie will be joining the younger children at the Graffham Water Centre in Cambridgeshire for the charity's first summer camp . "I'll show them how to shrug off unkind stares from others," she says. Ammie loves wearing fashionable sleeveless tops and she plans to show the youngsters at summer camp that they can too. "I do not go to great lengths to hide my burns scars," she says. “I gave up wondering how other people would react years ago.”
56. Ammie was taken to Glasgow Royal Infirmary because ____________ .
A. it was the nearest hospital away from her home
B. it was a hospital specializing in childhood disease
C. only there can skin grafts be performed
D. it has more advanced and specialized techniques to cure burns
57. How many operations will Ammie have to receive altogether?
A. 12 B. 13 C. 14 D. 15
58. The underlined phrase “shrug off” in the last paragraph is closest in meaning to ______ .
A. perform B. ignore C. accept D. tolerate
59. Which of the following best describes Ammie’s?
A. Strong-minded, optimistic and helpful
B. Shy, pessimistic and discouraged
C. Fashionable, sensitive and easygoing
D. Careful, confident and intelligent

（Reuters）--- A Michigan man credited his dog with saving his life by chewing off his diseased big toe as he lay passed out in a drunken stupor(昏迷)
Jerry Douthett, 48, who woke up on a Saturday night in late July in his Rockford, Michigan home to find his Jack Russell Terrier, Kiko, had gnawed off his right big toe.
“The dog always lies with me on the bed”, said Douthett. “That night, I woke up and looked down at my foot, and it was wet. When I looked, it was blood and there was the dog looking at me with a blood moustache.”
Douthett’s wife, Rosee, rushed him to a hospital where doctors found he was suffering from Type 2 diabetes. His toe was badly infected and surgeons amputated(截)the remainder of the toe.
Douthett’s wife, a registered nurse, had been urging him for weeks to have his infected toe examined by a doctor.
On the night Kiko ate his toe, Douthett said he had been out with his wife and drank about six or seven beers and a pair of giant margaritas—big enough to put goldfish in.
“I was self-medicating at this point,” he said. “The moral of the story is that the dog saved my life, because otherwise I would never have gone to see a doctor.”
The couple said they were amazed that Kiko appeared to know Douthett had an infection that needed treatment.
“He kind of chewed off the infected part and stopped at the good bone,” said Rosee. “We joked that we shouldn’t have had to pay the co-pay because he did half the job by chewing off half of the toe.”
【小题1】What does the underlined phrase “gnawed off” probably mean?
| A．bit away | B．cared for | C．sucked on | D．smelt out |
| A．Douthett’s wife was a doctor | B．Douthett’s wife felt something about his disease |
| C．Douthett never got that drunk | D．Douthett had seen a doctor for his disease |
| A．is in top physical condition | B．was trained at an early age |
| C．nearly cost Douthett his life | D．saved his master’s life |
| A．It is hard for the couple to explain the dog’s behaviour |
| B．Jerry Douthett went to see a doctor because of Kiko’s chewing his big toe.. |
| C．The couple shouldn’t have to pay the co-pay because Kiko did half the job. |
| D．Kiko didn’t hurt the good bone of its master. |

For medical students, real experience begins not in a classroom but at a teaching hospital. These doctors in training are guided. But sometimes accidents happen and the students get injured.
For example, they might stick themselves with a needle while treating patients. Such needle sticks are common. But a recent study found that medical students often fail to report them. Failing to report an injury like this can be dangerous if a patient, or a medical worker, has an infectious disease.
Researchers at Johns Hopkins University in Baltimore, Maryland, did the study, which involved a survey answered by almost 700 surgeons in training in the United States.
Almost 60% said they had suffered needle stick injuries when they were in medical school. Many said they were stuck more than once. Yet nearly half of those whose most recent incident happened in school did not report it to a health office. If they had, they would have been tested to see if they needed treatment to prevent an infection like HIV or hepatitis.
Most known cases of HIV or hepatitis are reported, but other possible infections often are not. Martin Makary, the lead author of the study, says medical students who are stuck put themselves and others in danger from infectious diseases.
Doctor Makary said, "A needle that goes through the skin needs to be as sharp as possible.” Doctors in training may have to do hundreds of stitches (缝线) in some cases to close the skin after an operation.
Doctor Makary said, “I support using blunt tip needles which are considered safer. This needle is still sharp enough to go through body tissue, but it does have a blunt tip, so that if it accidentally goes into my finger, it's much less likely to hurt me."
How common are needle sticks among health care workers? An estimated 600,000 to 800,000 of these and similar injuries are reported each year in the United States. But Doctor Makary says the real number may be much higher.
The study advises doctors to protect their hands by wearing two sets of gloves. It also urges hospitals to establish a special telephone number for medical workers and students to call if they are injured. The idea is for hospitals to send a clear message that there is no reason not to report this kind of accident.
1.It is dangerous for medical students not to report needle stick injuries because _________.
A. they don’t know how to treat themselves.
B. they may meet more needle sticks
C. it may cause some diseases
D. it may make patients sad.
2.If they report needle stick injuries, medical students will __________.
A. receive treatment B. be forbidden to use sharp needles
C. spend more time on training D. receive tests
3.The underlined word “blunt” in Paragraph 7 is the closest in meaning to “__________”.
A. not sharp B. not safe C. not long D. not thick
4.What do we know from the passage?
A. Doctors who don’t report needle stick injuries will be punished.
B. Needle sticks among health care workers will reduce sharply in the future.
C. Most needle stick injuries happen in the United States.
D. Two suggestions are given to protect medical workers and students.
5.Where can this passage most probably be found?
A. In an entertainment magazine B. In a science magazine
C. In a storybook D. In science fiction

There is a saying in French—“Si vieillesse pouvait, si jeunesse savait”—which means roughly “if age had the ability, if youth had the knowledge.” I was reminded of this saying the other day when I saw an interview with a distinguished Asian neurosurgeon(神经外科医生), now retired, about the impact of computer technology on modern surgery.
He was referring to the difficulty people of his age had in using the new techniques, but also to the fact that younger surgeons, who are more comfortable with the technology, lack some of the wisdom of experience.
It struck me that this problem is not just confined(局限于) to specialized fields such as medicine, but is widespread in modern life. There are many areas where the rapid growth of technology has widened the generation gap.
Young people are at ease with modern technology and propose all sorts of ways for using and developing it. But they often lack the experience needed to see further into the future to the possible dangers that a particular development may cause.
Older people see all sorts of difficulties and dangers, but are sometimes ignored, or even accused of being against progress, if they point out potential problems. Equally, they may see potential uses, but not have the technical skills to put them into practice themselves or the trust in the younger generation to do so.
Enthusiasm and inexperience come into conflict with caution and arrogance, usually with unsatisfactory results for both sides.
What is needed is the development of a partnership, based on mutual respect, which can deliver real progress by combining enthusiasm and caution in a constructive way, rather than in conflict with each other. The old need to give the younger generation the time, the resources and, above all, the authority to develop new ideas and use their skills. In exchange, the young need to turn more actively to the older generation to seek their advice and exploit their greater experience of the world in foreseeing and overcoming potential problems.
1.The passage is mainly about ________.
A．the impact of computer technology on modern surgery
B．an interview with a distinguished Asian neurosurgeon
C．new generation gap between the old and the young
D．a conflict between knowledge and experience
2.The French saying in the first paragraph is used to ________.
A．introduce the topic
B．show the difference between French and English
C．make readers confused
D．prove the writer’s wisdom
3.What did the retired neurosurgeon probably mention in his interview?
A．Old people’s enthusiasm in obtaining new technology.
B．Old people’s difficulty in using computers.
C．Young surgeons’ bad manners in working.
D．Young surgeons’ difficulty in getting experience.
4.In the writer’s view, what advantage do the older generation have?
A．They are happy with modern technology.
B．They are easy to learn new techniques.
C．They can foresee the future of the young generation.
D．They are rich in work experience.
5.What conclusion can be drawn from the last paragraph?
A．The young and the old should respect and learn from each other.
B．The young should teach the old modern technology.
C．The old should maintain their authority in every field.
D．The young and the old should work independently.
