B．The First Cloned Panda in the World
C．Exploring the Possibility to Clone Pandas
D．China—the Native Place of Pandas Forever
A.
With only about 1 000 pandas left in the world, China is desperately trying to clone the animal and save the enered species. That’s a move similar to what a Texas A ＆ M University researchers have been undertaking for the past five years in a project called "Noah’s Ark’.
B.
Noah’s Ark is aimed at collecting eggs, embryos, semen and DNA of enered 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.
C.
It is estimated that as many as 2000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in er of becoming extinct in the next 25 years.
D.
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.
E.
The entire procedure could take from three to five years to complete.
F.
"The nuclear transfer of one species to another is not easy, and the lack of available(capable of being used) panda eggs could he 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.
G.
"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. \

【单选题】What is true about the application of Professor Morgan’s research(). A. It can be used to prolong everyone’s life. B. It can help find cures for terminal illnesses. C. It can cure cancer and Aids. D. ...
A.
W: It’s well-known science fiction plot to freeze a body and bring it back to life years later.
B.
However, this may no longer be so far from the truth. Joining us from our Cardiff studio is Professor Andrew Morgan, who’s been doing some research into this subject. Professor Morgan.
C.
M: Yes, well, I’ve been looking into the ability of certain animals to freeze themselves for a certain amount of time, and then to come back to life when the circumstances around them change. And, what I’ve been working on over the past two years is the particular process that enables them to do this.
D.
W: What have you actually discovered
E.
M: I think it’s a particular chemical in the animals’ bodies which begins to work under certain circumstances. And I’m now experimenting with this chemical to see if I can get other animals that wouldn’t normally be able to freeze themselves to be able to do this.
F.
W: Have you had any success
G.
M: I have so far. It’s been going very well. And I’m reasonably confident that perhaps within ten years from now I’ll be able to freeze human beings for as long or as short a time as I would like to, and then bring them back to life again in exactly the same state that they were in before they were frozen…just as you can do with animals.
H.
W: And what’s the main application of your research
I.
M: I think the main application of this for human beings would be for people with terminal illnesses, such as certain types of cancer, AIDS. We could freeze them, find a cure for the illness and then bring them back to life again and administer the cure.
J.
W: I see. Well, this obviously is going to create great debate I would think as to the rights and wrongs of whether we should be actually doing this.
