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 a Texas A& M University researcher has 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, 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 over the next 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 cert ainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the lead ers 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.”

  　With the help of Gloria, his wife, Tom Peterson worked for many years to build a solid business selling television sets, stereo systems, and home appliances. Tom developed an excellent1with their full satisfaction guarantee and friendly service. He was proud ofhis high percentage of repeat2.

About five years ago, Tom was3 by the owners of a competing company,Stereo Super Stores. They wanted him to 4 them out. The price wasvery attractive. Everything looked good. Before making his final5Tom asked Gloria what she thought about the purchase. She told him that 6the numbers looked good it didn't feel 7 to her. However, Tom was soself－confidentand so convinced that this was a rare 8 ， he went ahead and made the 9.Within months he discovered that he had made a big 10. He had paidtoo much for a 11company. He tried as hard as he could to make itwork out, but he couldn't turn things 12. He was forced intobankruptcy (破产).He was about to lose everything, including his 13 business.

Tom was embarrassed, but he is a survivor. He looked at his situation. He decidedto 14 admit his mistake and, rather than getting stuck in lawsuits (诉讼), he would focus his 15onsaving and rebuilding his original business. He saw also that he had made amistake by not listening to his 16 ， and that he needed to learn from this 17. He dealt with the crisisin a way that delighted people, who in turn 18 respect for him. Oldcustomers poured into his store. He and Gloria 19 to changes inretailing (零售)and have built an even better business than before.

In the business world, it is natural to gain and lose, of20Peterson'sexperience is an example. Only those who regard their mistakes as gifts andlearn from them attract endless profits.
