The Mangrove Rivulus, a type of small killifish, lives in small pools of water in a certain type of empty nut or even old beer cans in the mangrove swamps of Belize, the United States and Brazil. When their living place dries up, they live on the land in logs(圆木), said Scott Taylor, a researcher at the Brevard Endangered Lands Program in Florida .
The fish, whose scientific name is Rivulus marmoratus, can grow as large as three inches. They group together in logs and breathe air through their skin until they can find water again.
The new scientific discovery came after a trip to Belize.
“We kicked over a log and the fish just came crowding out,” Taylor told Reuters in neighboring Guatemala by telephone. He said he will make his study on the fish known to the public in an American magazine early next year.
In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.
Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at a time, while lungfish found in Australia, Africa and South America can live out of water, but only in an inactive state. But no other known fish can be out of water as long as the Mangrove Rivulus and remain active, according to Patricia Wright, a biologist at Canada’s University of Guelph.
Further studies of the fish may tell how animals changed over time.
“These animals live in conditions similar to those that existed millions of years ago, when animals began making the transition(过渡)form water onto land, ” Wright said.

Get a reward for every bug you bring to live in new science museum exhibit.
In a city with trillions of American cockroaches(蟑螂), the Houston Museum of Natural Science has agreed to pay a quarter per bug-up to 1,000-as it seeks to populate a new insect exhibit alongside its Cockrell Butterfly Center.
Nancy Greig, the museum’s director insists the public payday for roaches isn’t just a marketing ploy(炒作).
“Absolutely, this wasn’t devised as a joke,” Greig said. “We needed more roaches for the exhibit, so I sent this message out to everyone in the museum asking people to bring them in. Well, someone decided to tell the press, and all hell has broken loose.”
“But we really do need cockroaches.”
“One might be forgiven for never considering how to catch a live cockroach. But it’s simple enough to fool them,” Greig said, “and even easier to catch them.” American cockroaches are the most common kind in Texas, measuring up to 2 inches long and invading homes.
Despite their less-than-attractive reputation, cockroaches actually aren’t that dirty. Greig even went so far as to call them “fastidious” saying they don’t enjoy rooting(用嘴拱食) in waste. They’re only dirty if, say, they used a sewer(下水道)line to gain access into a home.
The roaches collected by the museum will become part of a display in a new exhibit that showcases insects such as cockroaches, dung beetles and termites.
There’s more to like about roaches, too. They don’t bite, and they don’t carry diseases like a mosquito, so they’re generally safe to handle.
56.For what does the museum pay for cockroaches?
A.For a marketing ploy. B. It’s devised to make fun.
C.People really need them. D. For a new exhibit.
57.The underlined word “fastidious” probably means extremely ________.
A.clean B.dirty C.unpleasant D.fast
58.What do we know about American roaches?
A.It’s not easy for people in Houston to collect roaches.
B.They all measure 2 inches and are often found in homes
C.They don’t bite and they are free of disease.
D.We have reasons to like them.
59.Which of the following can serve as the best title for the passage?
A.The Houston Museum of Natural Science
B.A new exhibit
C.Quarters for cockroaches
D.A cockroach is lovely
1.A.By B.At C.In D.On
2.A.music B.song C.melody D.style
3.A.discovered B.acted C.invented D.designed

Governments and health officials around the world continued to take steps Tuesday against the outbreak of swine flu that has killed scores of people in Mexico and spread to the U.S., Europe and possibly Asia.
By early Tuesday, the swine flu outbreak in Mexico had caused in 152 deaths and more than 1,600 illnesses. So far, at least 113 cases have been proved worldwide, including 64 in the United States; six in Canada; 11 in New Zealand and two each in Spain the United Kingdom and Israel. None has yet resulted in death.
The World Health Organization on Monday raised its alert level from three to four on its six-level scale. The move means the U.N. agency has determined that the virus can transmit from human to human.
"In this age of global travel, where people move around in airplanes so quickly, there is no region to which this virus could not spread," said Fukuda, assistant director-general of the WHO.
Governments around the world struggled to prevent further outbreak. Some, like China and Russia, banned pork imports from the United States and Mexico. U.S. President Barack Obama said the outbreak was a cause for concern, not for alarm. The government urged travelers to avoid non-essential travel to Mexico.
The latest WHO report listed only seven proved swine flu deaths in Mexico but it was not clear why there was the discrepency.
Mexico City has closed all schools until at least May 6 to help curb(control) the spread of swine flu and ordered 35,00 public venues to close or serve only takeaway meals. In addition, bars, clubs, movie theaters, pool halls, gyms, sport centers and convention halls have been told to close until May 5. Armed police officers are also guarding hospitals in Mexico City while roads and schools in the city of 20 million people are deserted. Officials also have talked about shutting down the bus and subway systems.
57.How many people were found catching swine flu in Spain?
A. 2. B. 11. C. 6. D. 64.
58.When learning the outbreak of swine flu, the WHO was ____.
A. calm B. nervous C. shocked D. careful
59. Fukuda’s words suggest that _____.
A. he likes travel by air
B. global travel hasn’t been affected
C.this virus can spread quickly because of global travel
D. planes must be forbidden to take to prevent swine flu
60.The last paragraph mainly tells us _____.
A. Mexico has taken measures to control swine flu
B. Mexico City is too dangerous to live in
C. the normal life in Mexico has been changed
D. people in Mexico are badly in need of help
