题目：
MOSCOW — The Olympic flame in Vancouver had only been put out before President Dmitri A. Medvedev of Russia, angered over his country’s disappointing performance at the Winter Games, began calling for athletic officials’ heads.
“Those who are responsible for training for the Olympics must take responsibility,” Mr. Medvedev, who canceled his scheduled trip to the closing ceremony, said in Moscow on Monday. “They must have the courage to hand in their resignation(辞职报告). And if they do not have this determination, we will help them.”
Such language from the typically measured Mr. Medvedev strengthens the disappointment here with the nation’s athletics just four years before Russia hosts the next Winter Olympics in Sochi.
Russia is pumping billions of dollars into preparations for the 2014 Winter Games, which officials have considered as a symbol of Russia’s return to the top of the world stage.
Prime Minister Vladimir V. Putin said last week that Russia’s performance at the Olympics should be given “serious critical analysis.” “This critical analysis should be directed at improving the situation and creating the necessary conditions for the preparation and successful performance of our team in the Sochi Olympics in 2014,” he said. Russian athletes took home just three gold medals from Vancouver, compared with eight in the last Winter Games, in Turin, Italy.
Russia came in sixth place in the overall medal count with 15, just ahead of South Korea and trailing far behind its former cold war athletic rival, the United States, which led with 37.
For Russians used to seeing their athletes top international competitions, the last two weeks have been awful. Russian figure skaters fell, bobsledders turned over and, in a final embarrassment, the country’s much proud hockey team was smacked by Canada 7-3 and did not even make the medal round.
