With only about 1,000 pandas left in the...

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.”

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

2.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

3.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

Find which Direction Is South

Do you have a good sense of direction?If not,please take with you a compass. But if you forget to take a compass , you can still find your way.

It's never a good idea to imagine that the family member who was entrusted(委托〕with the job of map reading actually knows where the family is. You can tell by the "slightly confused look on their face that nothing on the ground seems to match the map. Never mind. The sun is shining and it’s still morning. If you don't know the exact time,you can still find out where south is,but you'll need to be patient.

①Find a straight stick and put it in the ground in a place where you can mark its shadow.

②Try to position the stick as vertically(垂直)as you can. You can check this by making a simple plumb line(铅锤线)with a piece of string(绳子) and weigh. You haven't got any string? Ok, use a thread from your clothes with a button tied at the end to act as a weight.

③Mark the end of the shadow cast by the stick.

④Wait approximately half an hour and mark the end of the shadow again.

⑤Keep doing this until you have made several marks.

⑥The mark nearest the stick will represent the shortest shadow, which is cast at midday, when the sun is highest in the sky and pointing to the exact south.

⑦Pick a point in the distance along the line between the shortest shadow and the stick.

⑧That point is south of where you are.

⑨Now you can turn the map, like you did before, and find which way you should be traveling.

1.To find the direction, we ought to be patient probably because ________.

A. it is not easy to find a proper stick

B. it is not easy to position the stick

C. it takes hours to make the marks

D. it takes about half an hour to make the marks

It`s not easy being a teenager (13—19岁的青少年)----- nor is it easy being the parent of a teenager. You can make your child feel angry , hurt, or misunderstood by what you say without realizing it yourself . It is important to give your child the space he needs to grow while gently letting him know that you’ll still be there for him when he needs you.

   Expect a lot from your child ,just not everything . Expect for health and safety problems , such as drug use or careless driving, consider everything else open to discussion . If your child is unwilling to discuss something , don’t insist he tell you what’s on his mind . The more you insist , the more likely that he 'll clam up   . Instead, let him attempt to solve(解决)things by himself. At the same time, remind him that you’re always there for him should he seek advice or help. Show respect for your teenager’s privacy(隐私).Never read his mail or listen in on personal conversations.

   Teach your teenager that the family phone is for the whole family . If your child talks on the family’s telephone for too long., tell him he can talk for 15 minutes ,but then he must stay off the phone for at least an equal period of time. This not only frees up the line so that other family members can make and receive calls , but teaches your teenager moderation(节制) .Or if you are open to the idea, allow your teenager his own phone that he pays for with his own pocket money or a part—time job.
