2．Frogs，toads and salamanders usually make us think of green，slimy little monsters．These monsters actually belong to a very special class of animals called the amphibians．Amphibians can live both on land and in the water．They commonly inhabit ponds，rivers，marshes and other wetlands．
Today，amphibians are becoming extinct very quickly from all the six continents where they are found．More than 25countries are reporting sharp drops in the populations of amphibians．In some places，embryos （胚胎） are dying； in others，adults are missing．Why are they dying off？
Scientists blame human interference．Industrial waste and toxic gases given out by factories，manufacturing plants and cars are steadily poisoning the breeding grounds of amphibians．Chemicals such as sulphur dioxide rise high into the atmosphere and mix with rain．This makes the rain acidic and thus kills off delicate amphibian embryos．
More rare species of amphibians are already gone．Costa Rica's Golden toads have not been seen since 1989．The Australian Gastric Brooding frogs are extinct．Leopard frog numbers are dropping in the Rocky Mountains．Leopard frogs live in the wetland regions in these areas．The wetlands are being drained to make way for highways，industry and new housing．
Another threat to the amphibians is the increased ultraviolet radiation．Ultraviolet rays come from the sun and are extremely harmful to living things．They can cause skin cancer in humans．Luckily for us，ultraviolet rays are blocked by a thick layer of ozone above the earth's atmosphere．Ozone is a special kind of oxygen which absorbs ultraviolet radiation．Now，the ozone layer is being destroyed by chemicals called CFC's which are given off by factories．A hole in the ozone layer was discovered over Antarctica in the late 1980's．As a result，more ultraviolet rays are reaching the earth and more amphibians are dying．
Just as the emergence of new infectious diseases such as Bird Flu are a threat to human and animal populations across the world，amphibian species are also facing their most significant threat from a little understood disease．A chytrid fungus is understood to be of the major causes of frog death across the world．
（Note：Answer the questions or complete the statements in NO MORE THAN TWELVE WORDS）

You have probably heard of the Mozart effect，It's the idea that if children or even babies，listen to music composed by Mozart they will become more intelligent，A quick Internet search says plenty of products to assist you in the task．Whatever your age there are CDs and books to help you taste the power of Mozart's music，but when it comes to scientific evidence that it can make you more clever，the picture is more mixed．
The phrase"the Mozart effect"was made up in 1991，but it was a study described two years later in the journal Nature，The media and the public showed great interest in the idea that listening to classical music somehow improves the brain．It is one of those ideas that sound reasonable，Mo-zart was undoubtedly a genius himself，his music is complex and there is a hope that if we listen to enough of it，we'll become more intelligent．
The idea took off，with thousands of parents playing Mozart to their children，In 1998Zell Miller，the Governot of the state of Georgia in the US，even asked for money to be set aside in the state budget so that every newborn baby could be sent a CD of classical music，It was not just babies and children who were exposed to Mozart's music on purpose，Even an Italian farmer proudly explained that the cows were played Mozart three times a day to help them to produce better milk．
I'll leaver the debate about Mozart effect on cows to farmers，but what about the evidence that listening to Mozart makes people more intelligent？More research was carried out but and analysis of sixteen different studies confirmed that listening to music does lead to a temporary improvement in the ability to handle shapes mentally，but the benefits are shor-lived and it doesn't make us more intelligent．
