With only about 1,000 pandas left in the world, China is desperately trying to clone the animal and save these in a dangerous situation. 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 these 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 probably 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 of one species to another is not easy, and the lack of available 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. The cooperation between us 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

A. The long time lasting cloning research could be successful.
B. The eggs transfers immediately result in having a baby.
C. The lack of nuclear transfer could be a major problem to have new pandas.
D. If species should die out, basic building blocks would heal them.
3. The best title for the passage may be__________.
A. China's Success in Pandas Cloning
B. Helping Ways to Avoid Extinction
C. Exploring the Possibility to Clone Pandas

D. Kraemer will work with Chinese scientists in clone researches

It is well-known that the panda lives _____there is plenty of bamboo.

A．in the place B．the place where C．in which D．where

Two friends visited the zoo together. The zoo was very large and it was 36 to go everywhere. They had to decide where and which animal to visit as their time was 37 . So both of them agreed not to 38 after choosing a 39 at every fork (岔路口).

A road sign at the first fork 40 one way to the lion quarters and the other to the tiger hill. They decided on the 41 after a 42 discussion because lions were “the king of the grassland”. The second showed a division (路口) going separately to the panda and peacock. They 43 panda as it was the nation’s treasure and went its way. Thus they made choices all along the way and each choice meant 44 what they could regret. But they had to make it 45 , for it brooked (容忍) no delay. If they hesitated they would miss 46 . Only 47 decision could offer more chances for sightseeing and 48 possible regret.

Life is 49 like this—choices often occur that one has to make, for example, between two 50 jobs, two fascinating wooers (追求者). To get one you 51 give up the other—you can get half of it. If you 52 weighing the pros and cons(权衡利弊) and calculating gains and losses, you will most likely 53 empty-handedness. Don’t be sad about it. 54 you have got half of the desirable things in life—something that is 55 to get.
