　　公输盘为楚造云梯之械，成，将以攻宋。子墨子闻之，起于鲁，行十日十夜而至于郢，见公输盘。

　　公输盘曰：“夫子何命焉为？”

　　子墨子曰：“北方有侮臣者，愿借子杀之。”

　　公输盘不曰。

　　子墨子曰：“请献十金。”

　　公输盘曰：“吾义固不杀人。

　　子墨子起，再拜，曰：“请说之。吾从北方闻子为梯，将以攻宋。宋何罪之有？荆国有余于地而不足于民，杀所不足而争所有余，不可谓智。宋无罪而攻之，不可谓仁。知而不争，不可谓忠。争而不得，不可谓强。义不杀少而杀众，不可谓知类。”

　　……

　　子墨子曰：“荆之地，宋之地，方五百里，此犹文轩之与敝舆也。荆有云梦，犀兕糜鹿满之，江汉之鱼，鳖鼋鼍为天下富，宋，所谓无雉兔鲋鱼者也，此犹梁肉之与糠糟也。荆有长松文梓楩楠豫章，宋无长木，此犹锦绣之与短祸也。臣以王吏之攻宋也，为与此同类。”

With only about 1 000 pandas left in the world, China is desperately trying to clone the animal and save the endangered 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’.

Noah’s Ark is aimed at collecting eggs, embryos, 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 2000 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 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.

"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. \

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 of species will probably die out in a century
