My friend Jennie Crossen gave her bone marrow (骨髓) to a 51-year-old woman with leukemia, a woman she has never met.

At the end of March, the Red Cross called back. Six different blood elements were tested; Jennie matched five completely and was about a 3/4 match of the sixth. So she was the best match.

In April, Jennie went for a complete physical exam by one of the doctors who would perform the surgery. The doctor had to make sure that it would be no threat to her. The doctor told her that the surgery would entail having two quarts of bone marrow extracted from her hip bones. Jennie would probably be released the same day the surgery took place and should expect to be sore for a couple of months.

"I didn't think it was that big a deal until I realized I was a match," Jennie said, "There wasn't a question in my head. It didn't seem like something that was going above and beyond."

Jennie was left with two very small scars on her lower back from the surgery and was given medication to help dull the pain. She still felt a great deal of pressure on her lower back. "Being only 21, I feel like I am not old enough to significantly impact someone's life," Jennie said, "It seems strange to me that I could possibly save this woman's life which was being cut short by cancer."

Three weeks after the surgery, Jennie received a call from the Red Cross representative who told her the transplant was successful. "I feel good, and I think it will actually work for her," she said, "So many people say they'd only donate if it was for a family member or close friend. This woman is someone's family and someone's friend. Obviously, no one she knows is a match, and the fact that you'd be able to help a perfect stranger is great."

The pillage (掠夺) and destruction of ancient shipwrecks and sunken archaeological sites by treasure hunters seeking gold and other valuables may be illegal under the terms of an international treaty under discussion by UNESCOs 188 Member States.

"Protecting our underwater heritage is extremely important and increasingly urgent as no site or shipwreck is now out of bounds for treasure hunters. New technologies have made deep-water wrecks easily accessible and these technologies are getting cheaper," warns Lyndel Prott.

According to estimates by commercial salvors (寻宝者), there are some three million undiscovered shipwrecks scattered across the worlds oceans. Even the figures for the known wrecks are impressive. The Northern Shipwrecks Database for example contains 65,000 ship loss records for North America alone from 1500 AD to the present. The Dictionary of Disasters at Sea by Charles Hocking (1969) lists 12,542 sailing ships and war vessels lost between 1824 and 1962.

Then there are sunken cities such as the trading town and pirate stronghold(海盗堡垒) of Port Royal in Jamaica, which disappeared beneath the waves after an earthquake in 1692. Or the remnants of ancient civilisations, such as the Lighthouse of Alexandria in Egypt, and the Neolithic villages being discovered under the Black Sea, which some believe could help explain Noah’s great flood.

These treasures of cultural heritage are under serious threat. Technology now allows extraordinary access to the ocean depths for deermined and well-financed treasure hunters. And the potential rewards are huge. In 1985, American salvor Mel Fisher discovered the wreck of the Seora de Atocha, a Spanish ship that sank off the Florida Keys in 1622 with her cargo of gold, silver and jewellery worth an estimated US $400 million.

An archaeologist can spend ten years or more studying a ship, conserving its objects and publishing its findings. We gain an enormous amount of information and knowledge from this work. With treasure hunters, all of this is lost. This is tragic, for humanity as a whole.

【1】Why is it important and urgent to protect our underwater heritage?

A. Underwater heritage is easily accessible to treasure hunters.

B. Underwater heritage is out of reach of archaeologists.

C. New technology makes protection of underwater heritage easier.

D. There is no law to protect underwater heritage.

【2】What is the third paragraph mainly about?

A. Shipwrecks discovered by commercial salvors.

B. The main cause of shipwrecks.

C. The history of sunken ships.

D. The figures of shipwrecks around the world.

【3】What happened to Port Royal in 1692?

A. It was washed away by flood.

B. It was beneath the waves after an earthquake.

C. It was discovered under the Black Sea.

D. It was rebuilt by Noah.

【4】Why is Mel Fisher mentioned in the fifth paragraph?

A. He risked his life in treasure hunting.

B. He was one of the most successful commercial salvors.

C. He made a great discovery of shipwrecks.

D. He had no trouble in finding a shipwreck.

阅读下列短文,从每题所给的四个选项 (A 、B 、C D )中,选出最佳选项。

Scientists at Harvard University have recycled a kidney(肾)-in a rat. The researchers removed a kidney from a dead rat. Later, the renewed kidney was put into a living rat. It wasn't perfect. It did, however, show signs of working like a kidney should.

"It's really beautiful work," Edward Ross, a kidney researcher at the University of Florida in Gainesville, told Science News. He didn't work on the new study.

Kidneys are bean-shaped and act like guards in the body. They clean the blood by removing waste and extra water. Every day, an adult's kidneys filter (过滤) enough blood to fill a bathtub half full. Along the way, they produce eight cups of urine (尿) from that waste and water. When a person's kidneys fail, all of that waste stays in the body. Such patients can quickly become very sick and die, unless they are regularly connected to a machine that filters their blood.

At any given time, about 100,000 people in the United States are waiting for a replacement kidney. But healthy donated kidneys are difficult to get. Either a living person must donate one, or a kidney must be removed from someone who just died and earlier had agreed to the donation. In either case, people receiving new kidneys face the r isk that their bodies will reject the donated ones.

But there may be another option. Researchers use knowledge of living things to grow or improve tissue that can aid human health. Harald Ott's team at Harvard started with a "used" kidney.

Scientists added kidney cells from rats and blood vessel cells from people to the matrix(母体). These cells attached themselves and began to multiply. Before long, they formed new kidney tissue.

The scientists placed this renewed kidney into another rat. There it produced a small amount of urine. This experiment shows that the lab-grown kidney can do at least some of the work performed by a healthy kidney.

The results are a promising first step toward helping people with serious kidney problems. "This is still very early, but they've come a long way," Ross said.

【1】What can we infer from Paragraph l?

A. Biology is a new and helpful science.

B. It's hard to put the rebuilt kidney into the rat.

C. Kidneys are very important to our life.

D. A used kidney may be recycled for new life.

【2】What does Paragraph 3 mainly talk about?

A. The relationship between kidneys and health.

B. The difficulty of curing serious kidney diseases.

C. The function and importance of kidneys.

D. The methods of curing kidneys diseases.

【3】 For what purpose does the author use the figure 100,000 in Paragraph 4?

A. To stress used kidneys are hard to get.

B. To show the great need for healthy kidneys.

C. To explain many American people get kidney diseases.

D. To call on people to donate kidneys.

【4】Which of the following is true according to the text?

A. The scientists are satisfied with the result of te experiment.

B. Ross is a kidney expert who is involved in the experiment.

C. The function of the renewed kidney is the same as a healthy kidney.

D. The renewed kidney produced a great deal of urine.

阅读下列短文,从每题所给的四个选项 (A 、B 、C D )中,选出最佳选项。

A recent announcement by scientists that they have successfully cloned the first human embryo(胚胎) has caused much debate and has shocked many people around the world. On the one hand, some scientists point out that if you clone an embryo, you can produce valuable tissues(组织) and organs that could be used to save human lives. On the other hand, many people, including some scientists, disagree and fear that if mankind interferes with (干涉) nature in this way, they may be on their way to producing a real-life Frankenstein's monster.

Cloning is producing an exact copy of a plant or an animal using its cells. The first mammal to be cloned successfully from an adult cell was Dolly—the sheep. She was born in 1996 and died in early 2003, at a much younger age than normal. When she was born, many people were angry because they thought cloning would create more diseases in the animal world. However, in general the scientists were praised for their wonderful scientific breakthrough.

The Scottish scientist who created Dolly, Ian Wilmut, is shocked that some scientists are now considering cloning human beings. Although he researches cloning, he has never thought of creating copies of humans. Instead, he thinks the scientists should concentrate on creating new tissues and organs that could eventually be used to cure diseases like cancer. However, some people consider that cloning human embryos with the intention of destroying them shows no respect for human lives.

While cloning human embryos is illegal in many countries, some scientists are already pushing ahead with the research so as to deliver a cloned human baby. Severino Antinori, an Italian doctor, is one of the leaders in this field of research. He has declared that he wants to be the first to clone a human being.

In China, scientists have focused their efforts on cloning animals, as well as stem cells to be used in medical research. China has succeeded in producing clones of cows and goats, and continues to research ways in which cloning can benefit mankind.

【1】Which of the following statements about cloning is TRUE according to the passage?

A. Cloning technology can only be applied to animals.

B. A cloned animal can live longer than a normal one.

C. People all over the world are happy about the birth of Dolly.

D. Cloning can produce valuable tissues and organs to cure human diseases.

【2】The reasons why some people disagree with cloning include the following EXCEPT that .

A. cloning may produce a real-life Frankenstein's monster

B. cloning might create more diseases in the animal world

C. cloning human embryos shows no respect for human lives

D. cloning can't help those who want to clone their dead children

【3】Who is in favor of cloning human beings?

A. Ian Wilmut.

B. Severino Antinori.

C. The author.

D. The Chinese scientists.
