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 fortable 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 fishs blood and measured its freezing point.The fish were taken from sea water 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 to2.05.That small difference is enough for the fish to live at the freezing temperature of the icesalt mixture.The scientists next research job was clear：Find out what in the fishs 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 sea water 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(分子) held in special positions within each big protein molecule.Because of its sugar content，it is called a glycoprotein.So it has e to be called the antifreeze fish glycoprotein，or AFGP.【语篇解读】你了解 the Antarctic cod(南极鳕鱼)吗？它们为什么在那么低的温度下仍能生存？其秘密在哪里呢？科学家会告诉你。1What is the text mainly about?AThe terrible
