　　ProfessorNow when I mention the terms “boom and bust”, what is that going to mind?

　　StudentThe dotcom crash of the ‘90s.

　　ProfessorOk. The boom in the late 1990s when all those new Internet companiessprung up and then sold for huge amounts of money.Then the bust around2000…2001 when many of those same Internet companies went out ofbusiness.Of course, booms aren’t always followed by busts. We’ve certainly seen timeswhen local economies expanded rapidly for a while and then went back to anormal pace of growth. But, there’s a type of rapid expansion, what might becalled the hysterical or irrational boom that pretty much always leads to a bust.See, people often create and intensify a boom when they get carried away bysome new industry that seems like it will make them lots of money fast. If you think that by the 90s, people would have learned from the past. If they did,well, look at tulips.

　　在讲座的开头部分，教师举例讲解了经济发展周期的一普遍现象-繁荣与萧条，语速较快，难度等级高。学生一开始就直接懵了，因为教授的讲座内容一开始就说了这节课的主题：“ Now when I mention the terms “boom and bust”,”而学生不知道boom和bust是什么意思。无形中注意力就会集中于在脑海里搜索什么事boom and bust。
