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.
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
2.Who will write up a report on Mangrove Rivulus?
A. Patricia Wright B. Researchers in Guatemala
C. Scientists from Belize D. Scott Taylor
3.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
4.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

The ruins of a Maya city have been discovered in Guatemala with the help of the remote sensing technique LiDAR. This lost city envelops sites like Tikal, Holmul, and Witzna, but shows that these famous areas are a small part of this lost urban network.
Hidden under the jungles of the Maya Biosphere Reserve site, more than 60,000 human-made features — homes, canals, highways, and more — have been identified in aerial (从飞机上的)images collected by some international researchers headed by the PAGUNAM Foundation, a Maya cultural and natural heritage organization. Those have experts rethinking the outlines and complexity of the Maya Empire.
These ancient peoples obviously created these imaginative cultures based on their known relics (遗迹), but the new research has suggested that the size of this lost society is far beyond what experts imagined. The findings will be explored in a one-hour documentary called “Lost Treasures of the Maya Snake Kings”, to be broadcast on the National Geographic Channel.
This breakthrough was possible thanks to LiDAR sensors, which can survey lands in 3D by bouncing pulses off the ground from unmanned air vehicles and others. LiDAR is exceptionally useful for detecting archeological(考古的)sites, as it gets through jungles and other features that hold up exploration on the ground. The technique has made many discoveries become a reality in recent years. For instance, major finds at Angkor, Cambodia and Caracol, Belize can explain what it did. The final goal is to survey Guatemala’s lowlands with it.
“There are entire cities we didn't know about now showing up in the survey data,” Francisco Estrada-Belli, one of the lead archeologists on the project, said in Nat Geo's coming documentary. “There are 20,000 square kilometres more to be explored and there are going to be hundreds of cities about the mysterious people who built this urban network there that we don’t know about, and we will push back the frontiers with the technology,” he added.
1.What does the underlined word "Those" in paragraph 2 refer to?
A.Jungles. B.Human-made features.
C.Researchers. D.Aerial images.
2.What does the author want to convey in paragraph 4?
A.The working principle of LiDAR sensors.
B.The process of researching Maya civilization.
C.Great importance of Guatemalans lowlands.
D.LiDAR’s contribution to discovering the relics.
3.Which words can best describe the lost Maya city?
A.Small and hidden. B.Famous and high-tech.
C.Vast and complex. D.Fully-explored and imaginative.
4.What will the archeologists do next?
A.Continue to explore the unknown. B.Upgrade the LiDAR technology.
C.Study the documentary carefully. D.Build a massive urban network,
