have long believed that reducing carbon dioxide gas in the atmosphere is the best way to slow the warming of the Earth.But new research suggests that reducing other gases may be a more effective way to slow climate change.The study was presented by American space agency scientist James Hansen and a team of scientists at NASAs Goddard Institute for Space Studies.They say that carbon dioxide levels have remained about the same during the past twenty-five years.Yet they say the average temperature of the Earths surface has increased.The researchers found that the combination of other so-called greenhouse gases traps more heat in the atmosphere than once thought.Such gases include methane,chlorofluorocarbons and ozone gases.The new research suggests that limiting carbon dioxide and other gases is the best way to prevent the Earth from getting too warm.Carbon dioxide in the atmosphere traps heat and keeps it near the Earths surface.It is produced by burning fuels that contain carbon such as coal,oil and wood.Three years ago,one-hundred industrial nations signed an agreement designed to reduce carbon dioxide levels in the air by the year Two-Thousand-Twelve.However,many countries objected to the climate change treaty.They said efforts to meet the goals of the treaty would harm their industries.The NASA scientists say more efforts should be made to limit the other gases.They say other greenhouse gases appear to trap more heat in the atmosphere than carbon dioxide.And technologies already exist to control most other greenhouse gases.NASA scientists say reductions in methane,ozone and black carbon gases also would improve public health and agricultural productivity.And they say the cuts would help the worldclimate and improve the air.Representatives of industries most affected by restrictions on carbon dioxide welcomed the findings.But some scientists fear the study might be used to ease pressure on industrial nations that produce more carbon dioxide.Others say it might be used to pressure developing countries to do more to control the release of harmful gases.But most scientists agree that reductions are needed in all areas to prevent further global warming.逆向法巧学英语02.New EvidenceA new study says that lakes and rivers in North America,Asia and Europe are freezing later and melting earlier than they did many years ago.Some scientists say the findings provide more evidence that the Earth is getting warmer.The findings were reported by John Magnuson and a research team from the University of Wisconsin,in Madison.The researchers collected historical information from Eighteen-Forty-Six to Nineteen-Ninety-Five about twenty-six lakes and rivers.The lakes and rivers are in the United States,Canada,Russia,Japan,Finland and Switzerland.The researchers found that many lakes and rivers were freezing about nine days later and thawing about ten days sooner than they did one-hundred-fifty years ago.They say those changes would mean a rise in air temperatures around the world of almost two degrees Celsius every one-hundred-fifty years.Scientists say even small changes in the Earths temperature can have serious effects on the environment.Most scientists think the Earth is getting warmer and that people are causing the problem.They say people are burning more fuels that trap heat in the atmosphere,such as coal and oil.But some scientists say global warming is not real.They say it is part of the natural system unaffected by human action.The new results alone do not prove that the Earths temperature is rising or that people are causing it.But scientists say their findings support the idea that the Earth is getting warmer.The researchers collected information from historical records.They got the information from newspaper reports,fur traders records,ship navigation records and notes of religious events.They discovered the dates of ice formation and breakup on three continents since Eighteen-Forty-Six.Some of the information was recorded because rivers and lakes were important for trade or transportation.People also took note of freezing or thawing as a sign of the seasons.The researchers note that the changes in ice formation on the lakes and rivers appear to have begun before Eighteen-Forty-Six.But they say the changes were happening at a slower rate then.They say most warming during the past one-hundred-fifty years is probably the result of human activity.逆向法巧学英语03.Ozone Hole GrowsThe hole in the protective ozone layer over Antarctica has grown bigger this year than at any time since scientists began measuring it fifteen years ago.Ozone gas in the upper atmosphere blocks harmful ultraviolet radiation from the sun.Ozone helps protect people from the suns harmful ultraviolet rays.Too much of this radiation can cause skin cancer or damage the eyes.U-V radiation can also threaten agriculture and the environment.Scientists say they are concerned that low ozone levels in the upper atmosphere could threaten heavily populated areas around the world.In the Nineteen-Seventies,scientists expressed concern about man-made chemicals called chlorofluorocarbons.They said these C-F-Cs were destroying the protective ozone layer.C-F-Cs destroy ozone in the presence of sunlight.They were once widely used in aerosol sprays and in cooling equipment.But most countries agreed to stop producing C-F-Cs after a worldwide ban in the late Nineteen-Eighties.Over the years,scientists have observed a huge loss in ozone over Antarctica.Antarctica is the ice-covered continent that covers and surrounds the South Pole.The loss of ozone takes place during its extremely cold winter season from June until September.Scientists believe that sunlight causes chemical reactions in the cold air over Antarcitica that can destroy ozone.This creates a huge ozone hole.The hole gets smaller as temperatures begin to rise in November.The temperature over Antarctica affects the size of the hole each year.The National Oceanic and Atmospheric Administration said that the ozone hole increased to more than twenty-seven-million square kilometers for a few days last month.Scientists say this is the largest size ever recorded.It is an area about the size of North Amercia.Record low temperatures in the upper atmosphere are believed to the cause.For several years,the hole has extended over populated areas at the southern end of South America.This year,cities in Chile and Argentina were hit with dangerous levels of ultraviolet radiation.And experts say it is possible that the situation could affect areas in South Africa,Australia or New Zealand.逆向法巧学英语04.Giant JellyfishLarge numbers of huge Australian jellyfish have been found in the waters of the Gulf of Mexico near the southern United States.Scientists want to know more about them and what long-term effects their presence may have.A jellyfish is an unusual sea creature.It is not a fish.It does not have a backbone.It has a soft body shaped like a bell.And it has long string-like structures called tentacles.There are more than two-hundred different kinds of jellyfish in all of the worlds oceans.The come in all shapes and sizes.Jellyfish are often a problem for people swimming at the beach because some of them can sting.Some jellyfish stings can be very painful.But most jellyfish are harmless to humans.Tens of thousands of spotted Australian jellyfish have washed up on beaches off the southern coasts of Alabama,Florida,Louisiana and Mississippi.Observers say they can easily be seen from the air.Scientists say the jellyfish have grown two times their normal size.They are more than one-half meter across and weigh,at least eleven kilograms.The huge creatures are causing problems for people living near coastal waters of the Gulf of Mexico.Swimmers are avoiding the beaches.And the jellyfish are getting caught in fishing nets and in boat engines.Scientists say the jellyfish may have a serious effect on the environmental system in the Gulf of Mexico.Scientists fear the jellyfish are eating the eggs and young creatures of the areas fish,shrimp and crabs.They say this may harm the valuable fishing industry in the area.Spotted jellyfish are native to Australia.They have been moving to the Caribbean Sea for twenty years.But this is the first time they have been seen so far north.They invaded the Gulf of Mexico in early June.Experts believe the jellyfish were caught in unusual waves that moved them north to the Gulf of Mexico.Scientists in Mississippi and Alabama are doing research to find out more about the invaders and how much they eat.They hope that increased rainfall or cold weather will kill or control the jellyfish.Scientists do not know if the jellyfish will survive the winter.If they do,their effect on the environment of the Gulf of Mexico could be an even bigger problem next year.逆向法巧学英语05.2000 SummerBOB DOUGHTY:And this is Bob Doughty with the VOA Special English program,EXPLORATIONS.The Summer Olympic Games begin this week in the city of Sydney,Australia.Today we tell about the Olympics and some of the American Olympic athletes.STEVE EMBER:The worlds most famous sports event is the Olympic Games.Five-million people are expected to attend the Summer Olympic Games this year in Sydeny,Australia.They include leaders and officials from many countries.About fifteen-thousand reporters are there.More than three-thousand-million people are expected to watch the games on television.More than ten-thousand athletes from two-hundred countries will compete in twenty-eight different sports in the Summer Games.They will be trying to win medals-gold for first,silver for second and bronze for third-in about three-hundred events.New additions to the Summer Olympics this year include synchronized diving,womens weight lifting,trampoline,womens pole vault and the triathlon.BOB DOUGHTY:The name of the modern Olympic Games comes from games held in ancient times.The games are said to have started in the ancient Greek city of Olympia,about two-thousand-seven-hundred years ago.The first thirteen Olympic Games were foot races during festivals held to honor the Greek god,Zeus.Winners were honored with a crown of olive leaves placed around their heads.Greece continued to hold the Games every four years for the next one-thousand years.Then the Games stopped.The ancient Romans banned the Olympic Games when they ruled Greece.They destroyed Olympic temples and sports fields.STEVE EMBER:The first modern Olympic Games were held in Athens,Greece in Eighteen-Ninety-Six.French diplomat Baron Pierre de Coubertin proposed a world celebration of sports like the ancient games of Greece.He believed the international event would provide a way for athletes of all nations to become friends.The official symbol of the Olympics shows five rings.Baron de Coubertin designed the symbol in Nineteen-Thirteen.The five rings represent the linking through sports of five parts of the world:Europe,Asia,Africa,Australia and the Americas.The colors of the rings are blue,yellow,black,green and red.The flag of every nation competing in the games has at least one of these colors.Under the rings is the Olympics saying in Latin:citius,altius,fortius.The words mean in English-swifter,higher,stronger.BOB DOUGHTY:The Olympic flame links the old and new games.In ancient Olympia,a fire burned in honor of the god Zeus during the sports competition.Now,runners carry a flame from Olympia to every new Olympics.This years fire was lit in Olympia,Greece on May tenth.Each person ran with it for one kilometer and then passed it to another runner.Before the flame reached Sydney,it was carried by more than thirteen-thousand people.The flame was flown from Athens,Greece,to the island of Guam in the South Pacific.It then was carried by individuals who traveled by foot,boat or vehicle through the Pacific islands to Australia.This Olympic flame has traveled farther than any other.This Friday,September fifteenth,a runner will use the flame to open the twenty-seventh Summer Olympic Games.The Olympic flame will burn during the Games.It will be put out during closing ceremonies.STEVE EMBER:Some of the athletes taking part in the Summer Olympics have trained for these events since they were children.One is American swimming champion Lenny Krayzelburg.Lenny Krayzelburg was born in the former Soviet Republic,Ukraine.He started swimming when he was five years old.A coach told Lennys father that he could be a great athlete.The coach said Lenny was burn to swim the backstroke.The Krayzelburg family left Ukraine and arrived in the United States when Lenny was thirteen.They settled in Los Angeles,California.Lenny continued to swim in competitions.In Nineteen-Ninety-Four,Lenny Krayzelburgs swimming skill won him financial support to attend the University of Southern California.In Nineteen-Ninety-Eight,he became the first swimmer in twelve years to win all the backstroke races at the World Swimming Championships.Last August,he broke the American record in the two-hundred meter backstroke for the fifth time.Later in the month,he broke the world records for the two-hundred meter and one-hundred meter backstroke.Swimming experts say Lenny Krayzelburg should win both the one-hundred and two-hundred meter backstroke races at the Summer Olympics this year.Lenny Krayzelburg says he will be unhappy if he does not win three gold medals in Sydney.BOB DOUGHTY:Three members of the same American family will compete in Sydney.Hazel Clark,Jearl Miller-Clark and Joetta Clark-Diggs are all members of the track and field team.Hazel and Joetta are sisters.Jearl is married to their brother,J.J.Clark.He is the coach for all three women.It is unusual for members of the same family to compete in the Olympics.But it has been done.Jackie Joyner-Kersee and her brothers wife Florence Griffith Joyner both competed in past Olympics.But they did not compete in the same event.The Clarks do.They all compete in the eight-hundred meter womens foot race.Hazel Clark is the youngest in the Clark family of runners.She was the fastest in the Olympic trials.Her brothers wife,Jearl Miles-Clark,was second.Jearl has already won medals in two earlier Olympic Games.Joetta Clark-Diggs finished third.She is the oldest,at thirty-seven.That was the first time three family members finished first,second and third in the same United States Olympic trials race.And this will be the first time three Americans competing in one Olympic race are from one family.Many people will be watching the eight-hundred meter race to see if the three members of the Clark family can win all three medals.STEVE EMBER:Another international sports event will take place in Sydney following the Summer Olympics.The Paralympic Games will be held from October eighteenth to the twenty-ninth.All the athletes who compete in the Paralympics have a physical disability.About four-thousand disabled athletes will compete this year.One American athlete who will compete in the Summer Olympics is already a Paralympics champion.Her name is Maral Runyan.She won the one-hundred,two-hundred and four-hundred meter races and the long jump at the Nineteen-Ninety-Two Paralympics.She also won the Pentathlon competition in Nineteen-Ninety-Six.This year,she will become the first legally blind athlete in the Summer Olympic Games.Marla Runyan suffers from an incurable eye problem called Stargardts Disease.It destroys part of the retina of the eye,and blocks the center of vision.Marla Runyan has been legally blind since she was nine years old.She has been taking part in track events since she was in high school.Marla Runyan will compete in the womens fifteen-hundred meter foot race at the Sydney Games.She says her goal was not to be the first legally blind Onlympian.She just wanted to take part in the Olympics.But her story has helped other disabled people find the strength to try to reach their goals.And Marla Runyan says that makes her feel very good.BOB DOUGHTY:The Two-Thousand Summer Olympic Games will end October first,after sixteen days of competition.The next Summer Games will be held four years from now,in Athens,Greece.The Summer Olympic and the Winter Olympic Games used to be held in the same year,every four years.Now,however,they are separated.The next Winter Games are less than two years away.The western American city of Salt Lake City,Utah is busy preparing for the Winter Olympics of Two-Thousand-Two.逆向法巧学英语06.Olympics Drug UseSTEVE EMBER:This is Steve Ember with the VOA special English program in the NEWS.Over the next two weeks,ten-thousand athletes from two-hundred countries will compete in the Summer Games in Sydney,Australia.They will try to live by the Olympic saying,faster,higher,stronger.But in the world of sports,experts say too many athletes use performance-improving drugs to reach these goals.The International Olympic Committee says drug use risks the health of athletes and violates the rules of sport.If an athlete fails a drug test before an event,he or she is banned from the competition.Athletes who fail a test after winning an event lose their medals.This year,the I-O-C says it is testing more Olympic athletes more often than ever.Some experts say this is still not enough.They say it is still too easy for athletes to use drugs and pass the tests.The International Olympic Committee bans six kinds of substances and
