     They made diverse points about the Internet that I had never thought about before£®For example£¬some experts think that the outcome of spending too much time on the Internet is the difficulty in forming social bonds£®They were also quite explicit about the fact how serious Internet users spend more time with their Internet friends than with their real-life friends from school and work£®This is an unfortunate aspect of the Internet that alarms us£®£¨·´¶Ô¹Ûµã£©

19£®We once had a poster competition in our fifth grade art class£®
"You could win prizes£¬''our teacher told US as she wrote the poster information on the blackboard£®She passed out sheets of construction paper while continuing£¬"The first prize is ten dollars£®You just have to make sure that the words on the blackboard appear somewhere on your poster£®"
We studied the board critically£®Some of US looked with one eye and held up certain colors against the blackboard£¬rocking the sheets to the fight or left while we conjured up our designs£®Others twisted their hair around their fingers or chewed their erasers while deep in thought£®We had plans for that ten-dollar grand prize£¬each and every one of US£®I'm going to spend mine on candies£¬one hopeful would announce£¬while another practiced looking serious£¬wise and rich£®

13£®GUATEMALA CITY £¨Reuters£©-A fish that lives in mangrove swamps£¨ºìÊ÷ÕÓÔó£©across the Americas can live out of water for months at a time£¬similar to how animals adapted£¨ÊÊÓ¦£©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£¨Ô²Ä¾£©£¬said Scott Taylor£¬a researcher at the Brevard Endangered Lands Program in Florida£®

     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£®
