US bees operation keeping groups have been attacked seriously by so called Colony （群体）Collapse Disorder．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 varroa 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.

Juanito Estrella has been a housekeeping manager on the US-based large passenger ship Carnival Spirit for 18 months and feels he has found the suitable position in his career(职业).He has always wanted to travel. “I guess I am a really restless spirit. I like traveling, so when the chance came, I jumped at it,” he says.

The chance came in the form of a newspaper advertisement for work on cruise ships（游船）.At the time Estrella was the housekeeping manager at a Melbourne hotel. He applied and, after two interviews, a medical check and police clearance, the job was his.

Estrella is responsible(负责的)for the cleanliness of the ship, making sure that 160 crew work properly. “I enjoy it because there is no other work-you wake up each day in a different place and a different culture. It’s exciting when you go to the next country and you don’t understand the language,” he says.
Estrella likes being busy and getting to know people from all over the world. The 1,000 crew come from 94 countries, and Estrella has learnt Spanish and a little Croatian.

But there is a downside. “You cannot get really drunk...because you have safety responsibilities to yourself and others,” he says. “You don’t really think about home. You start to think about home only when you get closer to your vacation and wonder what you’ll be doing.”

Life on the ship is anything but cruising. Estrella and his fellows work at least 10 hours a day, seven days a week. He warns the job is not for everybody. “You have to love being busy and be prepared to work every day-and to give up drinking too much alcohol.” In his spare time, if the ship sails into a port, Estrella explores it, otherwise he works out in the crew’s gym, goes on the internet or calls home.

A. He is very fond of traveling.

B. He doesn’t drink wine now.

C. He cannot speak a foreign language.

D. He used to be a housekeeping manager.

B. The work on the ship is not suitable for a married person.

C. Estrella can find no other job except the one on the ship.

D. The people on the ship are from 94 countries.
