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℃ 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 molecule. Because of its sugar content. It is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein, or AFGP.

Honeybees
Honeybees can do three kinds of jobs.
It is one of the most unusual insects in the world. Bees are special be
cause they divide up their honeybee work. Each bee has a certain job to do.
The busiest bee is the worker. Workers build the nest, called a hive. Inside the hive, workers make a honeycomb from wax(蜂蜡). They store honey there for food. Workers are always cleaning and fixing the hive. They even stand at the opening and fan their wings to cool the hive. Worker bees will attack anything—even people—to keep their hive safe.
Another kind of bee is the drone(雄蜂). Drones are male bees, and their job is to fly 
with the queen bee and mate with her. After the queen mates, the worker bees drive the drones away. The drones then starve to death.
The third kind of bee is the queen. Each hive needs only one queen, and her job is laying eggs. She can lay as many as 2, 000 eggs a day. The bee’s nest is called a _______.
| A．hive | B．honeycomb | C．drone | D．wax |
Which jobs do workers do?
| A．They lay 2, 000 eggs each day and build a nest. |

A famous doctor once received a little child who was badly ill. Thanks to his skill and care, his young patient got well and was soon able to get up and run about again.
The child’s mother was very much obliged to the doctor, and she called on him to thank him for what he had done for her child. “Doctor,” she said, “you have saved my little son. I don’t know how to thank you enough. I feel that money alone cannot repay you, so I have made 
this little purse with my own hands, as a sign of my gratitude. I hope you will accept it.” The doctor stood up and said coldly, “Madam, a little present like that is very nice between friends, but a doctor needs to be paid properly for what he has done.” The lady was so surprised and hurt so much that she could not reply for a moment. Then she said quietly, “Perhaps you will tell me how much your fee is?”“Fifty pounds”, he answered.
The lady opened the little purse and took out four fifty-pound bank notes. She handed one of them to the doctor, and put the other three back into the purse. She put the purse into her handbag and, saying good bye to the doctor, went out of the room.The doctor refused the lady’s purse because he thought ______.

Theodor Seuss Geisel was born in Springfield, Massachusetts in 1904. He was famous because of the books he wrote for children. They combine funny words, pictures, and social opinion.
Dr Seuss wrote his first book for children in 1937. It is called And to Think I Saw It on Mulberry Street. A number of publishers refused to publish it. They said it was too different. A friend finally published(出版) it. Soon other successful books followed. Over the years, he wrote more than forty children’s books. They were fun to read. Yet his books sometimes dealt with serious subjects.
By the middle 1940s, Dr Seuss had become one of the best-loved and most successful writers of children’s books. He had a strong desire to help children. In 1954, Life magazine published a report about school children who could not read. The report said many children’s books weren’t interesting. Dr Seuss decided to write books that were interesting and easy to read.
In 1957, Dr Seuss wrote The Cat in the Hat. He used less than 225 words to write the book. This was about the number of words a six-year-old should be able to read.
The story is about a cat who tries to entertain two children on a rainy day while their mother is away from home. The cat is not like normal cats. It talks. The book was an immediate success.

The hole in the Earth's ozone layer (臭氧层) has until now protected Antarctica from the worst effects of global warming. But scientists have warned that as the hole closes up in the next few decades, temperatures on the continent could rise by around 3oC on average, with melting ice contributing to a global sea level increase of up to 1.4 metres.
In the past decades the western Antarctic has seen rapid ice loss as the world has warmed, but the other parts of the continent have, paradoxically, been cooling, resulting in a 10% increase in ice in the seas around the region. This is because the hole in the ozone layer has increased cold winds in Antarctica, making much of the continent surface colder than usual.
But now that the gasses that cause the ozone hole have been banned, scientists expect the hole to repair itself within the next 50 to 60 years. By then the cooling effect will have faded out and the Antarctic will face the full impact of global warming. This means an increase in average air temperatures of around 3OC and a reduction in sea ice by around a third.
The biggest threat to the continent comes from warming seas. Robert Johnson, a scientist who monitors Antarctica ice sheets, said, "The ice sheets in Antarctica are hundreds of metres thick. But once warm ocean waters start flowing underneath, the ice will begin thinning and could break up very quickly. "Thinning ice sheets cause ice to break away from the continent and to melt even faster. Escaping ice from western Antarctica has already resulted in a 10% rise in global sea level in recent decades.
Johnson believes that international action to reduce global warming is required immediately or it may be too late. "Everything is connected - Antarctica may be a long way away but it is an important part of the Earth's system," said Johnson. "It contains 90% of the world's ice, 70% of the world's fresh water and that is enough, if it melts completely, to raise sea levels by 63 metres."
Even in a worse-case situation scientists don't expect the ice to entirely disappear, but predict that, because of the melting ice sheets, average sea level rise will be around 1.4 metres higher by the end of the century.The underlined word "paradoxically" (in Paragraph 2) most probably means "__".
| A．rapidly | B．approximately | C．contradictorily | D．apparently |
