13、chance to push further the frontiers of knowledge. I urge many of you, who read these line, to do the same.

47、ve“ - as in “Tip me your wallet or your life.“ Opponents of tipping will probably prefer this explanation, since it suggests the practice was originally a form of theft. A less reputable, but nonetheless charming, explanation is that in Renaissance (文艺复兴时期 ) coffee-houses, boxes were set near the do
48、or, into which customers could drop gratuities (赏钱 ). These boxes, according to the story, bore the legend “To Insure Promptitude (迅速 ),“ which was ultimately shortened to TIP.

By the turn of the century, we had made the custom our own, and the stereot
