Ten years ago, with only about 1, 000 pandas left in the world, China was desperately trying to clone(克隆)the animal and save the endangered species(物种). That was a move similar to what Texas A & M University researchers had been undertaking for the past five years in a project called “Noah’s Ark”(诺亚方舟).
Noah’s Ark was 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, said there would be enough of the basic building blocks to reintroduce the species in the future.
It was estimated that as many as 2, 000 species of mammals, birds reptiles would become extinct in over 100 years. The panda, native only to China, was 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 were then trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
“The nucleus 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 believed. “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, ”added Kraemer, who was 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. ”
At present, the project has worked. The number of the pandas has increased to more than 1, 500.

The island of Port Cros is in the south of France. I first visited it about ten years ago with my wife. I had read that it was a magical place and it seemed fascinating (迷人的), but I couldn’t believe that it was true. In fact, it was much more magical than the tourist brochures (指南) had said.
The island is mountainous and covered in trees. The water around the island is transparent like glass. When I first visited it, there was mist rising from the trees. The little harbor looked mysterious and remote: tall palm trees, a few shops and restaurants, no cars, motorcycles or bikes.
It is not by chance that the island has kept its natural beauty. Once, it was privately owned and the owners always wanted to keep it in its natural state. In 1963, Port Cros became a national park. The park directors made some rules to protect the island. They didn’t allow any new building projects. There is only one hotel and no camping is allowed. Visitors can’t use mountain bikes or smoke on the island. Sailing boats that visit the island mustn’t damage the bottom of the sea or pollute the water around it.
When we arrived, we started walking to the beach of Port-Man, which was the furthest beach from the port. It took us two hours and when we arrived, the beach was deserted. It seemed that we were the only people on the island. Time seemed to stop. It was so beautiful that we stayed there all day. I visited there again last summer. Nothing had changed. The island still looked magical and mysterious, still with few tourists. It must be wonderful to stay the night on the island, I thought. After all the visitors have gone, the island must be so quiet—a real paradise (天堂)!
1.The author got to know Port Cros at first due to _____.
A. some tourist brochures
B. his wife’s introduction
C. his first visit there
D. some TV programs
2.How has the natural beauty of the island been kept according to the text?
A. Foreign visitors are not allowed to visit it.
B. Nothing has been built in the park there.
C. Only bikes can be used on the island.
D. Sailing boats mustn’t pollute the water.
3.When the author first visited Port Cros, _____.
A. it was very sunny
B. there were few visitors there
C. it took them a whole day to walk to Port-Man
D. the island was deserted and he stayed there for a whole night

About 30 years ago, I left Cuba for the United States with my son. After getting settled finally in Brunswick, New Jersey, I enrolled(注册) my son in kindergarten. Several weeks later, my son’s teacher asked me to meet him at his office.
In the teacher’s office, and exchange of greetings was followed by his questions: “ Is your son mentally retarded(弱智的)? Does he suffer from any kind of mental disability?”
Was he talking about my wonderful Scola? No, no, it can’t be. What a helpless, lonely moment! I told him that Scola was a quiet, sweet little boy, instead. I asked him why he was asking me all these questions.
My son could not follow the teacher’s directions, he told me, and thus, Scola was disrupting
the class. Didn’t he know my son did not speak English yet? He was angry: “ Why hasn’t your son been taught to speak English? Don’t you speak English at home?”
No, I didn’t speak English at home, I replied. I was sure my son would learn English in a couple of months, and I didn’t want him to forget his native language. Well, wrong answer!
What kind of person would not speak in English to her son at home and at all times? “ Are you one of those people who come to this country to save dollars and sent them back to their country, never wanting to be a part of this society?”
Needless to say, I tried to tell him I was not one of “ those people.” Then he told me the meeting was over, and I left.
As I had expected, my son learned to speak English fluently before the school year was over. He went on to graduate from college and got a job, earning close to six figures. He travels widely and leads a well-adjusted, contented life. And he has benefited from being bilingual(双语的)。
Speaking more than one language allows people to communicate with others; it teaches people about other cultures and other places- something very basic and obviously lacking in the “educator” I met in New Jersey.
1.The teacher asked the author to his office________.
A. to work out a study plan for Scola B. to get Scola enrolled in kindergaten
C. to discuss Scola’s in-class performance D. to find a language partner for Scola
2.The author’s attitude towards being bilingual may best be described as __________.
A. positive B. critical C. casual D. passive
3.This text is likely to be selected from a book of __________.
A. geography B. medicine C. history D. education
