L14(1)：A noble gangster
There was a time when the owners of shops and businesses in Chicago that to pay large sums of money to gangsters in return for 'protection.' If the money was not paid promptly, the gangsters would quickly put a man out of business by destroying his shop. Obtaining 'protection money' is not a modern crime. As long ago as the fourteenth century, an Englishman, Sir John Hawkwood, made the remarkable discovery that people would rather pay large sums of money than have their life work destroyed by gangsters.

按新概念3的语速练下去，这练完了课本听力也提升不到哪里去啊，TED的演讲一句完整的话有一小半听不清。还是练一下精听吧，音标得再进行一次复习。
一句话，就是干。
