The Magrove 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 Guatgemala 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 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)from water onto land,” Wright said.

A.likes eating nuts |
B.prefers living in dry places |
C.is the longest living fish on earth |
D.can stay alive for two months out of water |

C.remain alive out of water |
D.be as active on land as in water |
A.It was made quite by accident |

D.It was helped by Patricia Wright |

The seven are Peking University, Beihang University, Beijing Normal University, Nankai University, Fudan University, Xiamen University and Hong Kong University.
Students who want to gain entrance to any of the seven universities will only have to sit one independent exam, according to the joint announcement.
"This will help lighten the students" load, otherwise they must take several exams for different universities," said the announcement.
Passing the exam could result in more than one interview chance, giving the students more opportunities to choose their favorite universities.
China"s college entrance exam system is undergoing reform as universities aim to select students based on independent criteria rather than just using the results of the national exam.
In 2003, Peking University and another 21 universities were allowed to pilot (试用) the reform by using their own criteria to independently select five percent of their students.
Now nearly 80 universities across the country have the right to select talented students based on their own exams.
Education experts regard universities selecting students according to independent examinations as conducive (有助的) to better understanding where the students" talents lie.
Although this may be the case, it has also created problems as students may sit many different exams as they often apply for a number of universities.
To relieve students from such pressures, the national education outline (2010--2020) released in July this year encourages high-level universities to group together to use the same exams.
小题1:If students want to be admitted to the seven prestigious universities , they can ______。
A.only pass the interview. |
B.only take the national exam. |
C.only take the independent exam. |
D.either take the national exam or the take the independent exam. |
A.It can reduce students" load to take several exams. |
B.The universities will have the same standard to test students. |
C.There will be less trouble marking students" test papers. |
D.It can avoid fierce competition among these universities. |
A.take the national exam. |
B.have one or more interview chances. |
C.be admitted to one of the universities. |
D.he trained to be adapted to universities life and studies. |
A.Students needn"t take the national exam. |
B.Students" education cost can be lowered. |
C.Students abilities and talents can be better found. |
D.It can encourage middle schools to recommend more qualified students. |
Only 13 percent of more than 2,400 people questioned in the telephone survey ranked being wealthy as most important to them, while 67 percent ranked free time as their top priority (优先考虑的事), higher than having a successful career, getting married, and having children. "Everyone wants free time to do the things they want to do, young, middle-aged or old," said Richard Morin, of the Pew Social ~ Demographic Trends Project, which conducted the survey. "So our desire to play unites us."
The survey also showed that people who were educated in university valued career success over wealth, so did middle-aged people. Not surprisingly, those who didn"t have money, ranked wealth very highly. This included minorities, first generation Americans and less educated people. The survey also revealed that a disproportionate (不成比例的) number of people under the age of 30 and retired people in the group made $ 20,000 or less a year. But the emphasis on wealth lessens with age, with younger people putting value on it but hardly any seniors. "It just diminishes (减弱) with time as the reality sets in that you would never be rich," Morin said. "But also, as for old people the reality sets in that you don"t have to be rich to lead a very comfortable and fulfilling life. "
While wealth was not at the top of people"s list of priorities, 43 percent still said it was somewhat important.
小题1:The survey showed that the majority of American people ranked ______ as the most important.
A.wealth | B.a successful career | C.marriage | D.free time |
A.Young people | B.First generation Americans |

A.Wealth is as important to the old as health. |
B.One needs to put money away for his retired life. |
C.One doesn"t have to be rich to live a satisfying life. |
D.One would never get rich until he retires. |
Santa Fe was founded in 1609 by the Spanish (西班牙人)on an old Indian village.In 1680 the Indians seized the place but only held it for twelve years before the Spanish retook it.
