Far from the land of Antarctica (南极洲), a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer. Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point. The fish were taken from seawater that had a temperature of -1.88°C and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05°C. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein (蛋白质) never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein, or AFGP.
1. What is the text mainly about?
A. The terrible conditions in the Antarctic. B. A special fish living in freezing waters.
C. The ice shelf around Antarctica. D. Protection of the Antarctic cod.
2.Why can the Antarctic cod live at the freezing temperature?
A. The seawater has a temperature of -1.88°C. B. it loves to live in the ice-salt mixture
C. A special protein keeps it from freezing.
D. Its blood has a temperature lower than -2.05°C.
3.What does the underlined word “it” in Paragraph 5 refer to?
A. A type of ice-salt mixture. B. A newly found protein.
C. Fish blood. D. Sugar molecule.
4.What does “glyco-” in the underlined word “glycoprotein” in the last paragraph mean?
A. sugar B. ice C. blood D. molecule
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(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 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 Pandas Cloning B. The First Cloned Panda in the World
C. Exploring the Possibility to Clone Pandas D. China —the Native Place of Pandas Forever
4.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
