Michael Phelps and his U.S. teammates crowned the greatest single Olympic performance Sunday morning with a win in the 4x100 - meter

medley relay.

     The victory gave Phelps his eighth gold

medal of the Beijing Olympics, the most golds

ever won by an athlete at one Games. With gold

No. 8, Phelps earned a singular place in the

Olympic record books.

      "There is no comparison in the swimming world for what Michael has done," said Gregg Troy, coach of U.S. swimmer Ryan Lochte, who finished third to Phelps in two races here in Beijing but also won gold alongside him in the 4x200 - meter freestyle relay. It' s hard to find comparisons even in the sports world overall. Phelps is solidly in the company of seemingly invincible superstars such as Michael Jordan and Tiger Woods.

"I think years and years down the road we' 11 realize more and more how amazing he is and how special he really is. " U. S. teammate Natalie Coughlin said. The 23 - year - old from Baltimore capped a brilliant meet at the Water Cube. He set a world record in every event aside from the 100 butterfly which he narrowly won on Saturday, completing a program of 17 races in nine days.

      Phelps has won 14'Olympic gold medals and 16 total medals. He holds the record for most medals won by a man, surpassing Soviet gymnast Nikolai Andrianov, who won 15 from 1972 -1980, Soviet female gymnast Larysa Latynina holds the record with l8.

      At the 2004 Athens Games, Phelps won six gold medals and two bronze. He has already said he'll swim in the 2012 London Games. Phelps' victories in Beijing include: 200 meter freestyle, 200 and 400 individual medleys, 100 and 200 butterfly, 4x200 free relay, 4x100 medley relay, and 4x100 free relay.

 

56. Which of the following would be the best title for the text?  

     A. Phelps wins 4x100 -meter medley relay

     B. Phelps writes Games gold history

     C. Phelps plans to attend 2012 London Games

     D. Phelps finishes his competitions

57. Why are Michael Jordan and Tiger Woods mentioned in the 3rd paragraph?  

     A. To emphasize Phelps' unique position in swimming.

     B. To indicate Phelps' great efforts to his championship.

      C. To attract the world's attention to the young Phelps.

      D. To memorize the two heroes' contributions to the world.

58. The world records Phelps has set do not include ____  

      A. 200 - meter freestyle                      B. 200 individual medleys

      C. 200 - meter butterfly                      D. 100 - meter butterfly

59. Which of the following is true of Phelps?  

      A. Phelps has won 18 Olympic gold medals till now.

      B. Phelps has got the most gold medals in Beijing Olympic.

      C. Phelps defeated Nikolai Andrianov in Beijing.

      D. Phelps won 8 gold medals at the Athens Games.

60. It can be inferred from the text that____  

      A Phelps is a swimming genius by nature

      ~. Phelps succeeded in Athens at the age of 18

      C. Phelps has won the most golds all by himself

 "The world's oceans are slowly getting more acidic,”say scientists. The researchers from California report that the change is taking place in response to higher levels of carbon dioxide in the atmosphere.

    The lowering of the waters’pH value is not great at the moment but could cause a serious threat to current ocean life if it continues, they warn. Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.

Increasing use of oil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater. Once in the water, it reacts to form carbonic acid. Scientists believe that the oceans have already become slightly more acidic over the last century.

    These researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change．"This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira. "And we predict the amount of future acidity will exceed（超過）anything we have seen over the last several hundred million years, let alone perhaps after rare disastrous events such as asteroid（小行星) impacts．”

    However, it is not absolutely clear what that means for ocean life．Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean life forms may be more sensitive to pH changes．Coral reefs and other organisms whose shells contain calcium carbonate（小行星) may be particularly affected if the water's acidity levels keep going up, the team predict. They could find it much more difficult to build these structures in water with a lower pH.

    In recent years some people have suggested storing carbon dioxide from power stations in the deep ocean as a way of dealing with global warming．But Dr Caldeira said that such a strategy should now be re-considered. "Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing-because in releasing CO2 into the atmosphere we warm the planet, and when CO2, is absorbed by the ocean, it reduces the amount of greenhouse warming.”

According to Dr Caldeira,__________ .

   A. ocean absorption of carbon dioxide is a good thing

   B. more oil fuels will be used in the near future

   C. scientists may predict climate changes with computer models

   D. the future situation of the amount of acidity is extremely serious

f the water's acidity level keeps rising,_________ .

   A. ocean life whose structures contain calcium carbonate may be affected

   B. the waters’pH value will become higher and higher

   C. organisms living near the surface are more sensitive to pH changes

   D. some disastrous events will occur more often than before

Most experts once believed storing carbon dioxide in the ocean would reduce________ .

   A. the CO2 absorbed by the ocean             B. the amount of greenhouse warming

   C. the acidity of the ocean                   D. the gradual release of CO2

The purpose of this passage is to_________ .

   A. show people the findings of a research team   B. inform people of how acid the ocean is now

   C. introduce Dr Caldeira and his team's research  D. warn people of the higher level of CO2
