One day a poor man was cutting a big piece of wood near a river. Suddenly his old axe(斧头) fell into the water. He felt very sad because he lost his only axe. Then all at once a beautiful fairy(仙女) came out and asked the man what was the matter.

“I have lost my axe.” he said. “It fell into the water when I was cutting the wood.” The fairy showed him a gold axe and asked, “Is this yours?” “No.” said the man.

The fairy then showed him a silver axe and asked again. “Is this yours?” “No.” again answered the man. Then she showed him the old axe.

“Yes, this is mine.” called out the happy man. “I know that well enough.” Said the fairy, “I only want to see if you can tell me the truth, and now I’ll give you the gold axe and the silver axe besides your own one.”

小题1:The man with his old axe fell into the river.

小题2:The fairy came out and asked what was wrong with him.

小题3:The sad man only wanted the gold and silver axes.

小题4:The fairy found his lost axe for the man.

小题5: From the story, we know that an honest man may get more.

     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."
