One evening while reciting the day's lecture to myself, I made an importantdiscovery. In trying to make my presentation as smooth as possible, I used thetransitional words "Now that we have discussed the major reason for thesuccess of Pharaoh Hophra, let us look at the minor reasons." At thatmoment I sTOPped still, for at no time did the professor ever cut up thelecture into TOPics and subTOPics; however, the TOPics and subTOPics werethere, waiting to be discovered.With this secret in mind, I found that I could take better notes during thelecture, and after class I could very easily supply the missing parts.

The TOPics and subTOPics were there,waiting to be discovered.
参考译文：这类标题和副标题都在那里，正等待着被发现。
