CGUATEMALA 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 nutsB. prefers living in dry placesC. is the longest living fish on earthD. can stay alive for two months out of water
According to the text, lungfish can________A. breathe through its skinB. move freely on dry landC. remain alive out of waterD. be as active on land as in water

Part IV Cloze (20 points) Directions: There are ten blanks in the following passages. And there are five choices marked A), B), C), D) and E). Match each blank with the right choice. Passage One Fire can help people in many ways. Fire can heat water, (41) () your house, give light and cook food. But fire can burn things too. Nobody knows (42) () people began to use fire. One story from Australia tells about a man a very long time ago. He went up to the sun by a rope and brought fire down. Today people know how to (43) () a fire with matches. Children sometimes like to play with them. But matches can be very dangerous. Fire kills people every year. So you must be careful about matches. You should also learn to (44) () fires. Fires need oxygen. Without oxygen they die. There is oxygen in the air. Cover a fire with water, sand, or in an emergency, with your coat or a blanket. This keeps the air (45) () a fire and kills it. Be careful with fire, and it will help you. Be careless with fire, and it might hurt you.(1). A.make B.warm C.how D.put out E.from(2). A.make B.warm C.how D.put out E.from(3).
