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 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(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 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) from water onto land,” Wright said.
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

Who will write up a report on Mangrove Rivulus?

A.Patricia Wright B.Scott Taylor
C.Scientists from Belize D.Researchers in Guatemala

According to the text, lungfish can____________.

A.breathe through its skin
B.move freely on dry land
C.remain alive out of water
D.be as active on land as in water

What can we say about the discovery of Mangrove Rivulus?

A.It was made quite by accident
B.It was based on a lab test of sea life
C.It was supported by an American magazine
D.It was helped by Patricia Wright

There are many American expressions about insects--- like bees, for example. Bees are known as very hard workers. They appear to be busy, moving around their homes, or hives (蜂窝). So you might say you were as busy as a bee if you spent your weekend cleaning your house. In fact, you might say your house was a beehive of activity if your whole family was helping you clean. You also might say you made a beeline for something if you went there right away. When we go to see a movie, my friend always makes a beeline for the place where they sell popcorn (爆米花) .
Here is an expression about bees that is not used much any more, but we like it anyway. We think it was first used in the 1920s. If something was the best of its kind, you might say it was the bee’s knees. Now, we admit that we do not know how this expression developed. In fact, we do not even know if bees have knees!
If your friend cannot stop talking about something because she thinks it is important, you might say she has a bee in her bonnet (女帽). If someone asks you a personal question, you might say “that is none of your beeswax”. This means none of your business.
Speaking of personal questions, there is an expression when their children ask, “Where do babies come from?” Parents who discuss sex and reproduction (生殖) say this is talking about the birds and bees.
Butterflies are beautiful insects, but you would not want to have butterflies in your stomach. That means to be nervous about having to do something, like speaking in front of a crowd. You would also not want to have ants in your trousers. That is, to be unable to sit still.

A. It is none of your beeswax B. You have a bee in your bonnet
C. It is the bee’s knees D. You are talking about the birds and bees

The young people who talk of the village as being “dead” are talking nothing but nonsense, as in their hearts they must surely know.
No, the village is not dead. There is more life in it now than there ever was. But it seems that “village life” is dead. Gone for ever. It began to decline about a hundred years ago. When many girls left home to go into service in town many miles away, and men also left home in increasing numbers in search of work, and home was where work was. There are still a number of people alive today who can remember what “village life” meant in the early years of the present century. It meant knowing and being known by everybody else in the village. It meant finding your entertainment in the village of within walking distance of it. It meant housewives tied to the home all day and every day. It meant going to bed early to save lamp oil and coal.
Then came the First World War and the Second World War. After each war, new ideas, new attitudes, new trades and occupations were revealed(展现)to villagers. The long-established order of society was no longer taken for granted. Electricity and the motorcar were steadily operating to make “village life” and “town life” almost alike. Now with the highly developed science and technology and high-level social welfare(福利)for all, there is no point whatever in talking any longer about “village life.” It is just life, and a better life.
Finally, if we have any doubts about the future, or about the many changes which we have seen in our lives, we have only to look in at the school playground any mid-morning; or see the children as they walk homeward in little groups. 0bviously these children are better fed, better clothed, better educated, healthier, prettier and happier than any generation of children that ever before walked the village street.
1.By saying that village is not dead, but “village life” is dead, the writer suggests that_______ .
A.those young people who talk of the village as being “dead” are wrong
B.the two statements are against each other
C.“village life” today is rather uninteresting

2.As is suggested in paragraph 2, villages in the past______________.
A.lived a simpler life than villagers today
B.knew fewer people than villagers today
C.found it difficult to enjoy themselves
D.like to wash themselves with cold water
3.The expression “…there is no point whatever in talking about…” in paragraph 3 means that______________.
A.there is no end to the talking about …
B.it is harmful to talk about …
C.it is not meaningless to talk about …
D.there is no reason for talking about …
4.What does the writer think of the “village life today”?
A.Dead. B.Worse C.Better. D.Unclear.

A new enemy is threatening Japanese traditions: leisure(闲暇). As part of its attempt to increase imports, the government is trying to get people to work less and spend more. The workers are disgusted.
The figures support the western prejudice(偏见) that the Japanese are all work and no play. Trying to force workers away from their desks and machines, the government said last April that the country should cut down from its 2,100 hours average work year to 1,899 hours and a five-day week by 1992. Beginning in February, banks and stock markets will be closed on Saturdays, staff of civil service will be forced out of their offices two Saturdays a month. The government hopes that others will follow that practice.
But some persuasion will be needed. Small companies are very angry about it and they fear competitors may not cut hours. The unions are no happier: they have even advertised in newspapers arguing their case against the foreign pressure that is forcing leisure upon them. They say that shorter hours are a disguised(隐性的) pay cut. The industrialists, who have no objection to the government’s plans, admit that shorter hours will help them cut costs. Younger Japanese who are supposed to be acting against their hard-working parents, show no sign of wanting time off, either. But unlike older workers, they do spend money in their spare time. Not content with watching television, they dance, dress up, sit in cafes, go to pop concerts and generally drive the leisure-industry boom. Now that they know how to consume, maybe the West can teach them to relax and enjoy themselves, too.
1.The purpose of getting the Japanese to have more spare time is that ______________.
A.the government wants to show more concern for the health of the people
B.the government needs to get more goods from abroad
C.the Japanese have been working too hard
D.the Japanese hope to change the western prejudice
2.The group of people who welcome the shorter-hour system in Japan is______________.
A.the small companies B.the industrialists
C.the unions D.the younger generation
3.The unions think that______________.
A.the shorter hours they work, the higher pay the can get
B.the more they work, the less leisure they can enjoy
C.the shorter hours they work, the less pay they can have
D.the greater pressure the government is forcing on them, the less happy they can be
4.The best title for this passage can be ______________
A.Oh no! Not Saturday Again! B.Leisure: the Greatest Threat!
C.Enjoy While You are Young! D.Less Work and More Play!
