. –What’s the temperature today?

--It’s 5 ℃ below _____. It is _____ cold.

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.
【小题1】 What is the text mainly about?

B
If you enjoyed the spring-like sunshine over the weekend and thought the weather has finally turned a corner, you’re sadly mistaken.
Chilly (寒冷的) days and grey clouds are forecast for the week—making it far too early to pack away the winter woollies.
Temperatures will struggle to rise above zero at night and fail to make double figures during the day.
People enjoy the spring sunshine in Sefton Park, Aigburth, Liverpool. Forecasters have predicted a return to chilly weather this week.
Met Office forecaster Charlie said, “It was a nice, dry, bright weekend in many parts and Monday is going to be a similar affair for many.”
“Temperatures will be between 5℃and 8℃, which is below average for the start of spring.”
The sun will disappear from the south of the country after today, with dry but cloudy conditions forecast for tomorrow and Wednesday. 
Wednesday will be warmest of the three, with temperatures peaking at 9℃. But this is still two degrees below the March average for the district.
Overnight, temperatures will drop sharply, with lows of minus 3℃for the next three nights.
“It will generally stay on the cold side of average,” said Mr. Powell.
The March misery comes at the end of the coldest winter for more than 30 years.
Temperatures in December, January and February struggled to stay above zero, with the UK’s average 1.5℃, making it the deepest freeze since 1978—79.
It claimed there was just a one-in-seven chance of a cold December to February.
The agency also sadly predicted a “barbecue summer”, saying it was “quite optimistic” that it would be warmer and drier than average.
Following the two mistakes, the Met Office has dropped its long-range seasonal forecasts and will instead publish a monthly prediction for Britain, updated once a week.
In its defense, it says that while short-term forecasts are extremely accurate, Britain’s size and geographical position makes long-term predictions much more challenging.
It also points out that it gave warning of any heavy falls of snow this winter.
60. According to the passage, the weather on Tuesday in the south might be _______.
A. dry but cloudy  B. sunny but chilly  C. sunny and warm  D. cloudy and chilly
61. Which of the following statements is true according to the passage?
A. British people can put away their winter clothes now.
B. The Met Office has shortened its forecast range.
C. The weather forecast becomes more and more accurate.
D. The agency was quite confident of long-term predictions.
62. Which of the following would be the best title for the passage?
A. The big chill isn’t over yet                         B. A warm spring finally arrives
C. A heavy snow is on the way                 D. The Met Office drops forecasts
63. From the passage, we can conclude ________.
A. the weather report is more and more important
B. British people become worried about bad weather
C. Britain has just experienced a very freezing winter
D. The Met Office can always predict any heavy snow falls accurately
