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 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.

49. 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

Passage Two

The other day I heard an American say to a Chinese student of English "You speak very good English." But the student answered, "No, no. My English is very poor." The foreigner was quite surprised at the answer. Thinking he had not made himself understood or the student had not heard him clearly, he said, "Yes indeed, you speak English very well." But the Chinese student still kept saying "No". In the end the foreigner gave up and was at a loss what to say. What's wrong with the student's answer? It is because he did not accept a compliment(赞美的话)as the English people do. He should have said "Thank you" instead of "No". He actually understood what the American had said. But he thought he should be modest. If he said "Thank you", that would mean he was too proud. According to the western culture, if someone says the dishes you have cooked are very delicious, you should say "Thank you". If someone says to a Woman "You look so beautiful with the new clothes on", she should be very happy and answer "Thank you". In our country we think being modest is a virtue and showing off a bad thing. But in the west, if you are modest and say "No, I'm afraid I can't do it well", then the others will take it for granted that you really cannot do it. If you often say "No", you will certainly be looked down upon by others. When asking for a job, if one says something like "Let me have a try on the job" instead of "Yes, I can certainly do it," he or she will never expect to get it. So in the west one should always be confident. Without self-confidence, he cannot go anywhere. Confidence is of great importance to one in a country where competition is quite keen.

40. Why was the American surprised at the Chinese student's answer?

A. Because he wondered whether the student could really speak good English.

B. Because he could hardly hear what the student had said.

C. Because he wouldn't like others to say "No".

D. Because the way to accept a compliment in China is not the same as that in the western countries.
