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(物种). 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”.

Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen 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 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.”

4. B。判断题。此题属考查考生的国际军事外交常识。其中四个选项文章中均没有提及到，但比较四个选项可以发现C选项较合情理(潜核艇内部设备属于国家机密，不允许别国的人入内，以免泄密)。

3. C。判断题。根据第 2 段倒数第 2 句话 But Russian insisted that only Russians work inside the submarine Kursk 可得出答案。

2. D。细节题。根据第 1 段倒数第 2 句话 …Northern Fleet Commander Admiral Vyachesav Popov ordered rescue ships into the area 可知答案。

1. B。细节题。根据第 2 段第 2 句话 Up till now, it’s believed that an explosion in the torpedo compartment in the nose of the Kursk was the likely cause 可知答案。

5. The underlined words “make contact with” in the first paragraph refers to the idea that the submarine Kursk can't_______.

A. get in touch after much effort with the naval command

B. send up the nuclear weapons in the training exercises

C. get the naval officers to return to the Northern Fleet

D. get in touch after much effort with Russian government

【答案与解释】 2000年8月12日，俄罗斯的一艘潜水艇连同120余名官兵沉入Barents海100多米的水底，在请求了挪威的援助下营救工作随即开始，事故原因众说不一，时至十月二十五日才真相大白。

4. Why did Russia insist that only Russian divers can work inside the submarine Kursk?

A. Because the Barents Sea is very icy and the weather is too cold.

B. Because Russia feared that the top secrets inside the Kursk will be let out.

C. Because Russian divers are much more skilled than those from Norway.

D. Because Russian government wants to bring the cost down to the lowest degree.
