Washington — The largest ozone (臭氧)hole ever observed has opened up over Antarctica, according to the scientists of the US National Aeronautics and Space Administration (NASA). They believe it is a sign that ozone — destroying gases produced years ago are just now causing the largest quantities of ozone to disappear.

　　This year’s South Pole ozone hole spreads over about 28.5 million square kilometers, an area three times larger than the landmass of the United States.

　　Pictures of the hole have been offered by NASA. The hole appears as a giant blue mass, totally covering Antarctica and stretching to the southern tip of South America.

　　“The last time the ozone hole was close to this size was in 1998, when it spread over about 27.2 million square kilometers,” NASA said.

　　Paul Newman, who works with NASA’s Total Ozone Mapping Spectrometer (TOMS) instrument on a NASA satellite, said ozone watchers had expected a big hole this year, but not this big.

　　The Antarctica ozone hole, first observed in 1985, is caused by the depletion (損耗) of Earth protecting ozone by human-made chemicals such as chlorofluorocarbons, known as CFCs.

　　“Even though these chemicals were not allowed to use from the beginning of 1987, they remain in the atmosphere and will continue to do so for years,” Newman said.

　　“This year’s large hole may have been caused by a change in a swirling high-level air current over Antarctica, which circles the area and contains the zone hole,” Newman said.

56. The text is mainly about ____ .

　 A. the discovery of the largest ozone hole           B. the discovery of the Antarctica ozone hole

　 C. the history of the Antarctica ozone hole          D. the size of the largest ozone hole

57. The time 1985 was talked about in the text because it was when the Antarctica ozone hole ____ .

　 A. was watched by Newman   B. was first closed   C. disappeared   　 D. was first watched

58. There is a giant ozone hole over Antarctica because ____ over there.

　 A. human-made chemicals have protected ozone     B. ozone has protected the earth

　 C. human-made chemicals have destroyed ozone     D. human-made chemicals have increased ozone

US bees operation keeping groups have been attacked seriously by so called Colony Collapse Disorder (蜂群衰竭失調(diào))．Almost 1/2 of their worker bees have vanished during the past season．This disorder has also been reported in Israel, Europe and South America．Bees fly away from the hive and never return．Sometimes they are found dead; other times they are never found．Many crops and trees depend on pollination--- by bees to help them grow． 

A new report says a virus may be at least partly responsible for the disorder in honey bee colonies in the United States．This virus is called Israeli acute paralysis virus．It was first found in Israel in 2004．Lan Lipkin at Columbia University in New York and a team reported the new findings in Science Magazine．Doctor Lipkin says the virus may not be the only cause．He says it may work with other causes to produce the collapse disorder．

The team found the virus in colonies with the help of a map of honey bee genes that was published last year．They examined thirty colonies affected by the disorder．They found evidence of the virus in twenty-five of them, and in one healthy colony．The next step is further testing of healthy hives．

The researchers suggested that the United States may have imported the disorder in bees from Australia．They say the bees may carry the virus but not be affected．

The idea is that unlike many American bees, the ability of Australian bees to fight disease has not been hurt by the varroasis mite．This insect attacks honey bees, which could make the disorder more likely to affect a hive．Australian bee producers object to these suspicions．

And some researchers suspect that bee production in the United States is down mainly because of the weather．Honey bees gather nectar from flowers and trees．The sweet liquid gives them food and material to make honey．But cold weather this spring in the Midwest reduced the flow of nectar in many flowers．Many bees may have starved．Dry weather in areas of the country could also be playing apart．

Wayne Esaias is a NASA space agency scientist who keeps bees in his free time．He lives in central Maryland, where he has found that flowers are blooming a month earlier than they did in 1970, which may be partly responsible for the disorder. Wayne Esaias is organizing a group of beekeepers to document nectar flow around the country.

What is the author’s attitude toward the cause of this disorder?

    A. Doubtful B. Neutral  C. Supportive   D. Negative

The passage is mainly developed by             .

    A. presenting the effect and analyzing its causes

    B. making comparisons between two countries

    C. providing data and examples

    D. following the time order

How many possibilities may be involved in the bee disorder according to the passage?

    A. Three    B. Four C. Five D. Six

From the passage we can infer that            .

    A. American bees are more likely to defend themselves against hurt from other insects than Australian ones

    B. A collection of plants production in the U.S may be influenced by the bee disorder

    C. Israeli acute paralysis virus should be responsible for the disorder

    D. The solution to the disorder will be found eventually

In a surprising discovery about where higher life can survive, scientists have found a shrimp -like creature and a jellyfish swimming beneath an Antarctic ice sheet.
About 180 meters below the ice where no light can get through, scientists had figured nothing much more than a few microbes (微生物) could exist.
That’s why a NASA team was surprised when they lowered a video camera to get the first long look at the underbelly of an ice sheet in Antarctica. A curious shrimp-like creature came swimming by and then parked itself on the camera’s cable. Scientists also pulled up a tentacle (觸須) they believe came from a jellyfish.
“We were operating on the presumption that nothing’s there.” said NASA ice scientist Robert Bindschadler. “It was a shrimp you’d enjoy having on your plate.”
“We were just gaga (狂熱的) over it,” he said when talking about the 7.5cm long, orange creature starring in their two-minute video. Technically, it’s not a shrimp. It’s a Lyssianasid amphipod, which is distantly related to the shrimp.
The video is likely to inspire experts to rethink what they know about life in harsh environments. And it has scientists thinking that if shrimp-like creatures can live below 180 meters of Antarctic ice in freezing dark water, what about other cold places? What about Europa, a frozen moon of Jupiter?
Cynan Ellis – Evans, a scientist of the British Antarctic Survey called the finding fascinating. He said it was possible the creatures swam in from far away and don’t live there permanently.
But Kim, who is a co-author of the study, doubts it. “The site in West Antarctica is at least 19 km from open seas. Bindschadler drilled a 20 cm-wide hole and was looking at a tiny amount of water. That means it’s unlikely that two creatures swam from great distances and were captured randomly in that small area,” she said.
“Yet scientists were puzzled at what the food source would be for these creatures. While some microbes can make their own food out of chemicals in the ocean, complex life like the shrimp can’t,” Kim said.
“So how do they survive? That’s the key question.” Kim said.
“It’s pretty amazing when you find a huge puzzle like that on a planet where we thought we know everything.” Kim said.
【小題1】. Scientists had believed that harsh environments could only have been populated by ______ .

A．jellyfishB．mammals C．microbesD．shrimp-like creatures
【小題2】According to Kim, the shrimp-like creature _________ .
A．swam great distances to AntarcticB．has always lived in the area
C．gradually evolved from shrimpsD．has nothing in common with shrimps
【小題3】The finding is significant in that __________.
A．it marks NASA’S first Antarctic biological study
B．it proves there is marine life in the Antarctic
C．it could inspire further study of life in harsh environments
D．it shows that Lyssianasid amphipod is closely related to shrimps
【小題4】. The last three paragraphs suggest that __________.
A．researchers will look at the places the creatures came from
B．ice scientists will drill deeper to find more creatures
C．scientists know very little about the planet they live on
D．further research will be done about what the creatures live on

The announcements by the NASA，in the form of several Web site postings and a video posted on YouTube，were in response to worries that the world will end on Dec．21，2012．

The doomsday(末日) rumour reached a high point with the release of the new movie “2012”，directed by Roland Emmerich．In the movie，Yellowstone blows up, showering the continent with black ash．Tidal waves wash over the Himalayas，where the governments of the planet have secretly built a ship which a select 400，000 people can ride out the storm．There are hundreds of hooks devoted to 2012，and millions of Web sites，depending on what combination of“2012”and“doomsday”you type into Google．All of it，astronomers say, is nonsense．“Most of what's claimed for 2012 relies on wishful thinking and ignorance of astronomy．”Ed Krupp， an expert on ancient astronomy，wrote in an article in the November issue of Sky＆Telescope．

“I get angry at the way people are being influenced and frightened to make money,” Morrison said．“There is no right to frighten children to make a buck．”suggested David Morrison，an astronomer at the NASA Ames Research Center in Moffett Field，Calif．He said he had been getting about 20 letters and e—mail messages a day from people as far away as India scared out of their wits．Morrison said he did not blame the movie for all this，as much as many other supporters of the Mayan prediction．But then，he said，“my doctorate is in astronomy，not psychology．”

In an e—mail exchange, Krupp said：“We are always uncertain about the future，and we always consume representations of it．We are always attracted by the romance of the ancient past．”A NASA spokesman，Dwayne Brown，said the agency did not comment on movies，leaving that to movie critics．But when it comes to science, Brown said, “we felt it was careful to provide a resource．”

If you want to worry，most scientists say，you should think about global climate change or nuclear war．But if ancient prophecies(預(yù)言)get you going，here are some things Morrison and the others think you should know．

64．Which of the following statements is TRUE according to the passage?

A．Dr．Morrison blamed the Movie“2011”for the panic it aroused in the public around the world．

B．People who watched the movie were seared and firmly believed that the end of the world was coming．

C．In terms of science it was better to provide evidence and theory at the same time．

D．Dr．Morrison thought it was not right to make money by frightening people．

65．It can be inferred from the text that         ．

A．a(chǎn)stronomers think that doomsday is likely to happen in the near future

B．the reason why the NASA posted web site postings was to make people interested in astronomy

C．scientists think we shouldn't worry about doomsday but show concern about environment protection

D．most astronomers agree that the world is not ending—at least anytime soon

66．Which of the following would be the best title?

A．A New Movie“2012”             B．Is Doomsday Coming?

C．End-of-the-World Stories          D．Astronomers Comment on Movies

67．What would the author probably discuss in the paragraph that follows?

A．Evidence that the Mayans thought something special would happen in 2012．

B．What will really happen in 2012．

C．The reason why there is no need to worry about doomsday．

D．Ancient stories about the end of the world．
