Children, too young to comprehend wherefore this woman should be shut out from the sphere of human charities, would creep nigh enough to behold her plying her needle at the cottage-window, or standing in the doorway, or labouring in her little garden, or coming forth along the pathway that led townward; and, discerning the scarlet letter on her breast, would scamper off with a strange, contagious fear.

年纪尚幼、不理解这个女人为什麼会被人类的仁慈拒之门外的孩子们，会蹑手蹑脚地走近前来，窥视她在茅屋窗边飞针走线，窥视她位立门前，窥视她在小花园中耕作，窥视她踏上通往镇子的小径：待到看清她胸

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。
