听力原文： Finally there is one more element to business success that we havent talked about. I know what you think Im going to say, luck and youre partially right. Good entrepreneurs know how to make their own luck and that means being in the right place at the right time with the right product. Let me give you a little example, early in this century, if you’re a traveler by train and subway and you happen to get a little thirsty in the station, where would you go for some water? There were no big soda machine at every corner or even drinking fountains, yet there were thousands of thirsty travelers out there, well, what they did was drank water out of one little tin cup that was passed from one thirsty commuter to the next. Thats right, everybody drank out of the same cup, and you can bat it didn’t get washed after every user. Will, that was the right time for the right product and there was a man who had it. His name is H M and his product was the disposable paper cup. He came up with it just as the nation was becoming concerned about their health risks associated with the tin cups. Laws were passed outlying the things; reports were published showing just what sorts of germs can be passed around from sharing them. Mr. M road that way to become the best known producers of one of the most successful paper products of all time. He originally called his product health cups, but later changed the nature, so can anyone guess what that name might be?52．
