Before 1900,many theories existed as to the cause of yellow fever(黄热病).Some doctors were sure the disease was air-born; others felt that it was spread from person to person. Dr. Carlos Finlay, a well-known Cuban doctor of that time, had long held the theory that it was caused by the bite of mosquitoes(蚊子).But neither the pubic nor the doctors then accepted his idea.

Despite this, Walter Reed, an American doctor sent to study yellow fever in Cuba, went to talk with Finlay. Reed, after reading a lot on the subject, had begun to think that Dr. Finlay might be right. Then Reed and his comrades set to work at once. Outside Havana, they set up a laboratory and began experiments to test the theory. The experiments were successful. Now we know: A period of about two weeks must pass before a mosquito, after feeding on a sick person, could infect another person. The sick person had to have yellow fever a certain number of days before the mosquito biting him was able to carry the disease.

Before Nicolas Sarkozy became French president, he was asked if he thought about presidency when he looked in the mirror while shaving. “Not just when I’ m shaving,” he answered.

When Francois Hollande, now president-elect (总统当选人) of France, was asked the same question, he replied: “Do I see myself as president? No, I am a presidential candidate. A candidate must not think himself president; he must give hope that he becomes president.”  

Hollande has promised to be a “normal president” – something Sarkozy certainly was not. Sarkozy celebrated his election in 2007 at a world-class Parisian restaurant. He took holidays on the yachts (游艇) of wealthy businesspeople. Hollande, by contrast, was still going around Paris on his three-wheeled motorbike at the start of this year. One member of his party said he looked “more like a pizza delivery man” than the next president.

“That is the key to Hollande’s success because the election is turning into a sort of referendum (公民投票) for or against Nicolas Sarkozy,” Eric Dupin, a journalist and political observer told Global Post. “Francois Hollande is the one who appears not only as his main opponent politically, but also as his complete opposite psychologically.”

When he was the Socialist party leader, Hollande was nicknamed “the marshmallow (软糖)” because he hated fights. Sarkozy, by contrast, is known to be loud and aggressive.

When faced with Sarkozy’s verbal attacks during the election, Hollande stayed calm. This sometimes annoyed even his own supporters. “I wish he would just let go and savage (用暴力对付) Sarko,” one Hollande voter said to the Guardian.

But Hollande still knows how to fight. Stéphane Le Foll, a Socialist MEP who has been one of Hollande’s closest advisors for 17 years and is co-directing his campaign, said Hollande had quietly planned his presidential bid for 10 years. “I think we all underestimated this guy,” Alain Minc, one of Sarkozy’s closest friends and advisers, told Reuters.

Hollande was born in 1954 into a middle-class family. He lived through the 1968 protests that nearly overthrew the French government. “They shocked him, but also politicized him, he said in a recent interview, making him understand that change was possible,” reported the New York Times. When Hollande was 15, he told friends he expected to become president.

“I didn’t come to the first rank either by chance or by obsession (执迷),” Hollande said in an interview with Reuters. “I got there because I put myself in this situation, and because I deserved it.”

A. Sarkozy is more confident than Hollande

B. Hollande is more modest than Sarkozy

C. Hollande is less ambitious than Sarkozy

D. Sarkozy is more humorous than Hollande

69. What is the key to Hollande’s success in the presidential election according to Eric Dupin?

A. His dislike of fights.

B. His careful plan for the presidential bid.

C. How different he is from Sarkozy.

D. The gentle way in which he ran his campaign.

70. What did Hollande think he owed his success to, according to the article?

A. His good luck.                          B. His devotion and efforts.

C. His obsession with politics.        D. His personality and experience.

71. What is the purpose of the article?
