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和D)中,选出最佳选项。

Nearly a quarter century after a German boy threw a message in a bottle off a ship in the Baltic Sea, he's received an answer.

A 13yearold Russian, Daniil Korotkikh, was walking with his parents on a beach when he saw something lying in the sand.

“I saw that bottle and it looked interesting, Korotkikh told The Associated Press on Tuesday.“It looked like a German beer bottle and there was a message inside.”

It said, “My name is Frank, and I'm five years old. My dad and I are travelling on a ship to Denmark. If you find this letter, please write back to me, and I will write back to you.” The letter, dated 1987, included an address in the town of Coesfeld.

The boy in the letter, Frank Uesbeck, is now 29. His parents still live at the letter's address.

The Russian boy and the German man met each other earlier this month through an Internet video link. The Russian boy said he did not believe that the bottle actually spent 24 years in the sea. He believed it had been hidden under the sand where he found it for a long time.

Uesbeck was especially happy that he was able to have a positive effect on a life of a young person far away from Germany. “It's really a wonderful story, he said.“And who knows? Perhaps one day we will actually be able to arrange a meeting in person.”

C.Frank Uesbeck and Daniil Korotkikh have met each other in person.

D.Daniil Korotkikh and Frank Uesbeck have got in touch with each other.

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.
