GUATEMALA CITY (Reuters) – A fish that lives in mangrove swamps(紅樹(shù)沼澤)across the Americas can live out of water for months at a time, similar to how animals adapted(適應(yīng))to land millions of years ago, a new study shows.
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(圓木),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(過(guò)渡)from water onto land,” Wright said.  
小題1:The Mangrove Rivulus is a type of fish that _______. 
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
小題2:Who will write up a report on Mangrove Rivulus?

小題3:According to the text, lungfish can________
A.breathe through its skin
B.move freely on dry land
C.remain alive out of water

小題4:What can we say about the discovery of Mangrove Rivulus?
A.It was made quite by accident

C.It was supported by an American magazine
D.It was helped by Patricia Wright

In the United States, train transportation is unpopular compared with cars and airplanes. Most people like traveling by car or by air. Officials of the United States Department of Transportation made a study in 2001. The study is about how many miles Americans traveled by different means of transportation. They only studied trips longer than 50 miles. The study showed that fifty-six percent of all miles were traveled in personal vehicle. Forty-one percent were traveled in an airplane. Two percent were traveled in a bus. And less than one percent of miles were traveled in a train. Amtrak is the national provider of train transportation in the United States. In the past ten years, the number of its passengers has increased by eighteen percent. Although the number of passengers has increased, it is still very small now. In countries such as France, Germany, or Japan, more people use trains. There are several reasons why many people ________________________.
Firstly, Americans love to drive their own cars. On highways, cars can travel as fast as trains. These highways connect all major cities in America.Secondly, many travelers like to be independent. When they use their own cars they can decide when to travel. Thirdly, many buses travel between major cities. Bus travel is less costly than train travel. In a huge country like the United States, cities are far away from each other. In some cases, travel from one city to another by train may take more than a day. Airplanes can carry passengers over long distances much faster. People who do not want to spend long time traveling by train decide to fly. For these people saving time is the most important thing.

The interview had been going on for about 20 minutes and everything seems to be going well.Then, suddenly, the interviewer asks an unexpected question, "Which is more important, law or love?"
Job applicants in the west increasingly find themselves asked strange questions like this.And the signs are that this is beginning to happen in China.
Employers want people skilled, enthusiastic and devoted.So these are the qualities that any reasonably intelligent job applicants will try to show no matter what his or her actual feelings are.In response, employers are increasingly using questions which try and show the applicant’s true personality.
The question in the first paragraph comes from a test called Kiersey Personality Sorter.It is an attempt to discover how people solve problems, rather than what they know.This is often called aptitude (能力) testing.
According to Mark Baldwin of Alliance many job applicants in China are finding this type of questions difficult. When a Chinese person fills out an aptitude test he or she will think there is a right answer and they may fail because they try to guess what the examiner wants to see.

Russia and the United States have completed the largest spy exchange since the Cold War.On Friday, at an airport in Vienna, Austria, an American plane and a Russian plane landed, parked side by side and exchanged occupants
The United States freed ten admitted Russian agents.The men and women were arrested in late June and pleaded(承認(rèn)) guilty on Thursday.
In exchange, Russia freed four Russians serving prison sentences on charges of spying for the West.The men include Igor Sutyagin, an armed researcher who always denied the charges.Some considered him a political prisoner.
The United States deported(驅(qū)逐) nine Russian and an American citizen born in Peru.Some raised children while living quiet lives as married couples.
Russia’s Foreign Ministry praised the exchange, saying, “The action improved Russian-U.S.relations.”
The group was accused of trying to gain information on American nuclear weapons, foreign policy and politics for the SVR — Russia’s foreign intelligence service.
The ten were only charged with plotting(陰謀) to act as undeclared foreign agents.They were not charged with the more serious crime of spying, so the extent(程度) of their success as spies is not clear.
One of the Russians, Anna Chapman, drew attention with her looks and stories of her New York party life.Hr lawyer, Robert Baum, said she had not passed secret information to Russia or received any payment.He also said, “She was accused of communicating with a Russian official through a laptop to laptop communication, without the government specifying the nature of the communication.”
