Three Yale University professors agreed in a discussion that the automobile was what one of them called “Public Health Enemy No.1 in this century.” Besides polluting the air and overcrowding the cities, cars are involved in more than half the disastrous accidents, and they contribute to heart disease “because we won’t walk anywhere any more”, said Richard Weinaman, professor of medicine and public health.

Speaking of many of those man-made dangers of the automobile, Arthur W.Galson, professor of biology, said it was possible to make a kerosene-burning turbine car that would “lessen smog by very large factor”.But he expressed doubt whether Americans were willing to give up moving about the countryside at 90 miles per hour in a large vehicle.“Americans seem wedded to the motor car—— every family has to have at least two, and one has to be a convertible (敞篷车) with 300 horsepower,” Professor Galson continued.“Is this the way of life that we choose because we treasure these values?”

For Professor Sears, part of the blame lies with “a society that regards profit as a supreme value, under the illusion that anything that’s technically possible is, therefore, morally justified”.Professor Sears also called the country’s dependence on its modern automobiles “terrible economics” because of the large horse-power used simply “moving one individual to work”.But he admitted that Americans had painted themselves into a corner by allowing the national economy to become so dependent on the automobile industry.

“The solution,” Dr.Weeinerman said, “is not to find a less dangerous fuel but a different system of inner city transportation.Because of the increasing use of cars, public transportation has been allowed to wither (衰弱) and grow worse, so that if you can’t walk to where you want to go, you have to have a car in most cities,” he declared.This, in turn, Dr.Weinerman contended, is responsible for the “arteriosclerosis (动脉硬化)” of public roads, for the pollution of the inner city and for the middle-class movement to the suburbs.

With only about 1, 000 pandas left in the world, China is desperately trying to clone(克隆) the animal and save the endangered species.That’s a move similar to what Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”.w.w.w.k

Noah’s Ark is aimed at collecting eggs, embryos and DNA of endangered animals and storing them in liquid nitrogen.If certain species should become extinct, Dr.Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.

It is estimated that as many as 2, 000 species of mammals, birds and reptiles will become extinct in over 100 years.The panda, native only to China, is in danger of becoming extinct in the next 25 years.

This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit.They are now trying to implant the embryo into a host animal.

The entire procedure could take from three to five years to complete.

“The nuclear transfer(核子移植)of one species to another is not easy, and the lack of available (capable of being used)panda eggs could be a major problem,” Kraemer believes.“They will probably have to do several hundred transfers to result in one pregnancy (having a baby).It takes a long time and it’s difficult, but this could be groundbreaking science if it works.They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A & M, the first-ever attempt at cloning a dog.

“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark.We’re both trying to save animals that face extinction.I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do.It’s a research that is very much needed.”

1.The aim of “Noah’s Ark” project is to _______.

A.make efforts to clone the endangered pandas

B.save endangered animals from dying out

C.collect DNA of endangered animals to study

D.transfer the nuclear of one animal to another

2.According to Professor Kraemer, the major problem in cloning pandas would be the lack of    _______.

A.available panda eggs

B.host animals w.w

C.qualified researchers

D.enough money

3.The best title for the passage may be _______.

A.China’s Success in Pandas Cloning  

B.The First Cloned Panda in the World

C.Exploring the Possibility to Clone Pandas

D.China —the Native Place of Pandas Forever

4.From the passage we know that _______.

A.Kraemer and his team have succeeded in cloning a dog

B.scientists try to implant a panda’s egg into a rabbit

C.Kraemer will work with Chinese scientists in clone researches

D.about two thousand species will probably die out in a century
