GUATEMALA CITY（Reuters）---- A fish that lives in mangrove swamps（红树沼泽）across the Americas can live out of water for months at a time, similar to how animals adapted（适应）to land millions of years ago, a new study shows.
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.

Having a husband means an extra seven hours of housework each week for women, according to a new study. For men, getting married saves an hour of housework a week. “It’s a well-known pattern,” said lead researcher Frank Stafford at University of Michigan’s Institute for Social Research. “Men usually work more outside the home, while women take on more of the housework.”
He points out that differences among households (家庭) exist. But in general, marriage means more housework for women and less for men. “And the situation gets worse for women when they have children.” Stafford said.
Overall, times are changing in the American home. In 1976, women busied themselves with 26 weekly hours of sweeping-and-dusting work, compared with 17 hours in 2005. Men are taking on more housework, more than doubling their housework hours from six in 1976 to 13 in 2005.
Single women in their 20s and 30s did the least housework, about 12 weekly hours, while married women in their 60s and 70s did the most – about 21 hours a week.
Men showed a somewhat different pattern, with older men picking up the broom more often than younger men. Single men worked the hardest around the house, more than that of all other age groups of married men.
Having children increases housework even further. With more than three, for example, wives took on more of the extra work, clocking about 28 hours a week compared with husbands’10 hours.

C. About 13 D. About 6
3.What kind of man is doing most housework according to the text?
A. An unmarried man. B. An older married man.
C. A younger married man. D. A married man with children.
4.What can we conclude from Stafford’s research?
A. Marriage gives men more freedom.
B. Marriage has effects on job choices.
C. Housework sharing changes over time.
D. Having children means doubled housework.
