? Francis Bacon once said：Studies serve for delight，for ornament，and for ability. So，if you expect to be a knowing，talented and professional man，you should fall in love with studying and indulge in it. Reading maketh ａ full man conference ａ ready man，and writing an exact man. Bacon also said that. And therefore，if ａ man writes more，his memory could be improved；if he talks more，he could have ａ quick wit；and if he reads more，he could much seem to know that he doth not.
