While drunken driving may be on the decline, traffic safety experts remain puzzled over how to deal with another alcohol?related danger: drunken pedestrains.

Pedestrians struck and killed by cars often are extremely drunk. In fact, they are intoxicated more frequently-and with higher blood?alcohol levels-than drunken drivers who are killed in accidents, various studies have shown. Forty percent of adult pedestrians involved in fatal crashes have a blood?alcohol level of at least 0.10-which by law in most states signifies intoxication-compared to only 25 percent of drivers in deadly accidents, according to recent federal data.

Some types of pedestrain accidents have been declining nationally, especially those involving children, but the number of adult pedestrians who are drunk when killed in traffic has remained relatively steady at 2500 a year. The total number of pedestrians killed annually in U.S. traffic accidents is at least 7000, or one of every seven highway accidents resulting in death.

“We’re dealing here, we think, with a very severe drinking problem that leads to a severe highway safety problem,” said Richard Blomberg, president of Dunlap and Associates Inc, in Norwalk, Coon.

Blomberg, whose consulting company found a very high rate of alcohol involvement in a controlled study of pedestrian accidents in New Orleans, was among several researchers who spoke on the topic at the annual meeting of the Research council’s Transportation Research Board(TRB) in Washington in January.

Pedestrian accidents have not received enough attention in the past, according to Kay Colpitts, who chairs the board’s committee on pedestrians. Few methods exist to monitor walking habits, she said, and researchers have been mystified about how to prevent disasters.

A recent announcement by scientists that they have successfully cloned the first human embryo 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 disease 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，his intention has never been to create copies of humans. Instead，he thinks research efforts 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 life.

While cloning human embryos is illegal in many countries，some scientists are already pushing ahead with research so as to deliver a cloned human baby. Severino Antinori，an Italian doctor，is one of the leaders in this kind 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 stern 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.

51. 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.

52. The reasons why people are anti-cloning include the following EXCEPT that_______.

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

B. cloning might create more disease in the animal world

C. cloning can’t help those who want to clone their dead children

D. cloning human embryos shows no respect for human life

53. Who is in favor of cloning human beings?

A. Ian Wilmut. B. Severino Antinori.
