For someone who is such a successful investor, Warren Buffett comes off as a pretty ordinary guy. He was born on August 30, 1930. ______1______ He used to go door-to-door and sell soda water. When his family moved to Washington, Buffett became a paperboy for The Washington Post. Buffett ran his five paper routes and even added magazines to round out his product offerings. While still in school, he was making $175 a month, a full-time wage for many men.
______2______ He spent $1,200 on 40 acres of farmland in Nebraska. He and a friend also made $50 a week by placing pinball machines in barber shops. They called their venture (企业) Wilson Coin Operated Machine Co. Already a successful small-time businessman, Buffett wasn’t interested in going to college but ended up at the University of Pennsylvania—his father encouraged him to go. ______3______ But he was turned down in what had to be one of the worst admission decisions in Harvard history. The outcome affected Buffett’s life, for he ended up attending Columbia Business School, where he studied under Professor Benjamin Graham, the father of securities analysis who provided the foundation (基础) for Buffett’s investment strategy. From the beginning, Buffett made his fortune from investing. He started with all the money he had made from selling soda water, delivering papers, and operating pinball machines. Between 1950 and 1956, he grew his $9,800 to $14,000. ______4______ And then he gradually drew in other investors through word of mouth and very attractive terms. ______5______ He doesn’t collect houses or cars or works of art, and he disdains (鄙视) companies that waste money on expensive cars, private dining rooms, and high-priced real villa. He is a creature of habit—same house, same office, same city, same soda water.
A. Then Buffett applied to Harvard Business School.
B. Buffett is more likely to be found in a four-star restaurant.
C. When he was 14, Buffett still kept great interest in investment.
D. Even as a young child, Buffett was serious about making money.
E. Buffett’s investment strategy mirrors his lifestyle and overall philosophy.
F. From there, he organized investment partnerships with his family and friends.
G. One thing is for sure about Buffett: he is happy doing what he is doing.
2置于句首，可能是个主题句。整个第二段讲述的是年轻时的Buffett以及Buffett和朋友们一起创业开公司的情况，所以C选项When he was 14, Buffett still kept great interest in investment.;
