Far from the land of Antarctica，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 slowed.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 ℃ 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 ℃.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 things 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 anti-freeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein.It has many small sugar molecules(分子)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 anti-freeze 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 ℃.
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 ℃.
3．What does the underlined word“it”in Paragraph 5 refer to?
A．A type of ice-salt mixture.
B．A newly found protein.
4．What does“glyco-”in the underlined word“glycoprotein”in the last paragraph mean?
解析：选A。词义猜测题。根据“Because of its sugar content，it is called a glycoprotei n．”这句话可以推断出前缀“glyco-”应该和sugar有关。
