Geniuses amaze us, impress us and make us all a little jealous．How do they differ from the average person? Scientists are working hard to figure out that answer．Tune in to the National Geographic Channel to find out about the discoveries they’re making in the series My Brilliant Brain.

When Marc Yu was only two years old, he began to play the piano．After a year, he started learning pieces by Beethoven．Now he’s a world-famous concert pianist at age eight．He learns newer and more difficult pieces with ease and can identify any note he hears．He seems to be specially designed for music．In Born Genius, National Geographic looks at the science behind child prodigies (神童) to explain why some children seem to be born without limits.

Genius didn’t come naturally to Tommy McHugh．His came only after he nearly died from bleeding in his brain．After recovering, McHugh’s head was filled with new thoughts and pictures．So, he began to express them in the form of poetry and art．Now, he’s a seemingly unstoppable creative machine．Sufferers of autism and brain injury have shown that great mental ability can sometimes come from damage or disease．Accidental Genius explores this puzzling relationship.

Can normal people be trained to be geniuses? Susan Polger has shown no signs of extraordinary intelligence．Yet, during her childhood, she studied thousands of chess patterns and learned to recognize them immediately．As a result, she was able to beat skilled adult players by age 10 and can now play up to five games at the same time without even seeing the boards．Make Me a Genius examines what it takes to turn an ordinary brain into that of a genius.

If becoming a genius were easy, we’d all be one．Yet, there is much more to super intelligence than simply being born lucky．Learn more about amazing brains this month on National Geographic’s My Brilliant Brain.

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 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℃ 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 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(分子) held in special positions within each big protein molecules. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein, or AFGP.

49. 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 Antarctic.                   D. Protection of the Antarctic cod.

50. 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℃.

51. 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.

52. What does “glycol” in the underlined word “glycoprotein” in the last paragraph mean?

A. sugar                      B. ice                   C. blood                      D. molecule
