　　Beneath the ocean’s surface, an active world surrounds the globe．A lot of spotted fish swim through coral reefs．

　　But time is running out for these underwater treasures．Last month, at the National Oceanic and Atmospheric Ad－ministration's coral－reef meeting, researchers warned that 60% of the world's coral could die within the next 25 years．About 27% of the living underwater cities have already been lost．

　　Though some coral formations are similar to lifeless stone, coral is made up of tiny animals called coral polyps．They grow and divide to build coral colonies．their bones are left behind．New corals grow on top, forming reefs．The complex reef ecosystem covers less than 1％ of the ocean floor, yet supports about 25％ of all marine life．An ecosystem is a partnership between living things and their environment．

　　The destruction of coral reefs puts many species at risk of extinction．Some researchers say that at least 1 million species of plants and animals live in the world's reefs．On October 29, scientists said they had discovered new reef species in the waters off Hawaii．

　　Water that is warmer than normal can cause deadly coral bleaching(漂白)．Coral contains tiny algae(藻類)．They give coral its beautiful color．Coral uses the algae to create food and grow．At high temperatures, corals get stressed and release the algae．Without the algae, coral loses its color and starves．The weakened coral becomes more sensitive to sun－light and disease．Last year, warming in the Caribbean Sea bleached more than 90% of the coral on many reefs．

　　London has more than nine million visitors every year．They come and visit some of the most famous places in England：Big Ben, the Tower of London and the River Thames．

　　You can see some of the most interesting places in the city by getting on one of London's tour buses．It has an open roof and let you off at any places you want to visit．

　　The River Thames is London's main waterway．It has shaped the capital's landscape, history and geography．So one of the best ways of making sense of the city is to make a trip along the river．Much of the riverbank can now be walked along, particularly the south bank．

　　The clock tower of the Houses of Parliament, Big Ben, has become one of the main symbols of London．It rises up nearly 100 m to a golden point above the clock and a 13-ton bell．The sound of the bell, which you can hear at the beginning of many television and radio programs, has become well-known throughout the nation．No visit to London is complete without a look at the Tower of London, in the eastern part of the city．After Big Ben, the Tower may be London's most visited tourist spot．

　　Sightseeing in London is great, but it can get ________．So the best way to start the day is to fill up on an English breakfast．For starters, have an egg, bacon, sausages, tomatoes, mushrooms, black pudding and fired bread．Then finish off with toast and jam, and a large pot of tea．You can buy an English breakfast in nearly every hotel, and many restaurants and cafes．

　　An English pub is a good place to stop for lunch and a drink．You can get hot or cool food and try one of England's beers．Or you can sit outside one of the many roadside puns and cafes in London, and simply watch the busy world go by．

　　Many contemporary amateur athletes and swimmers would have broken world records if they had taken part in the first Olympic Games．Since then, records have fallen so much in track, field and swimming events as performance has greatly improved．If records fall, it is usually due to better equipment, training and diet; but recently improvements have begun to slow down．In Sydney, only three runners achieved Olympic bests with no world records．Some experts predict a ceiling for many events, such as 9.5 seconds for the 100 metres－Maurice Greene's current record is 9.79 seconds．

　　However, past predictions are nearly always wrong．All the levels of performance predicted in the 1930s had been reached by the 1970s．Ron Maughan, from Aberdeen University, believes that if more people around the world took part in organised sport, more records would have fallen．

　　One factor is the use of performance-enhancing drugs, or“doping”．Ben Johnson would still be the 100 metres world record holder if he had not been caught taking drugs．Other records remain doubtful, like Florence Griffith's 100 metres record back in 1998．Did she take drugs?If current Olympic champion, Marion Jones, took such drugs, she would probably have broken that world record more than once．

　　Unless we are careful,“gene-doping”will be the next big threat．

　　For medical purposes, scientists have already found ways to build muscle and increase strength through gene therapy．If gene therapy were used now, it would be almost impossible to find out．In the future, genetically-modified athletes might be able to run the 100 metres in 8 seconds or the marathon in under two hours．

　　However, if a generation of genetic monsters(轉(zhuǎn)基因怪物)were created, it would show that the whole point of sport has been lost．

　　It would be much better to forget the records and return to the original Olympic spirit－taking part is _______________．

1．What's the best title for the passage?(within 10 words)

2．Which sentence in the passage is the closest in meaning to the following one?
