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(氮). If certain species should become extinct , Dr. Duane Kraemar, a professor in Texas A&M University 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.”

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

According to Professor Kraemer , the major problem in cloning pandas would be the lack of _______.

A. available panda eggs           B. host animals

C. qualified researchers           D. enough money

The best title for the passage may be ______.

A. China’s Success in Panda Cloning

B. The First Cloned Panda in the World

C. Exploring the Possibility to Clone Pandas

D. China---the Native Place of Pandas Forever

Annie had just begun school. Her parents were tired of the methods they were using to correct her behavior, including scolding (训斥), and taking away privileges (特权). Annie still needed to be scolded for her bad behavior, but her parents felt the good things she did needed to be recognized. So, they began to spend more time recognizing the improvements (改进) in Annie’s behavior and the good things she did every day rather than like before when they only noticed her bad behavior. Within a few weeks Annie began to change her attitude and her behavior improved.

Praise is one of the most powerful tools parents can use to teach their children good skills and help them grow. Praise works well when it is given and when you remember to use it frequently. It is important to praise all good behavior. Look for the good things your child does. Praise will have a lot of effects on your child. Use the 4 to 1 rule. For every bad behavior you notice, find four good behaviors or reasons to praise. It is a good way to remember to look for good behavior.

Remember to praise the things your child has already done well, or improvements in his behavior and new skills. Show your agreement by smiling and touching his shoulder or back. Be sure to say what your child did well in detail. Tell your child how good behavior helps and that it is liked by others.

What was the result of recognizing Annie’s good behavior?

A. She started to correct her bad behavior.

B. She was tired of her parents’ scolding.

C. She was not scolded for her bad behavior.
