这时，他心里正在想："《学士手册》确是一本荒谬的书，一定是出自一伙稀有蠢材的手笔，才会在谈到人类思想代表作时去对拉辛的三个悲剧作分析，而莫里哀的喜剧反而只分析一个。"

First, in Chapter 3, a two-dimensional interacting birth-death process is established and by means of two-dimensional moment generating function, the equivalence in mean between our model and the classic prey-predator model are proved.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
