Grounded on the first chapter, new and original in content, the second and the third chapters, employing the theories in phonetics, writing, rhetoric, semantics and aesthetics, further discusses the rhetorical and the semantic functions of the comma in English and Chinese: rhetorically speaking, the comma can be used to clarify, to expound, to substitute, to emphasize, to contrast, to complement, or to vivify; semantically speaking, the comma itself can carry information to indicate certain meaning, or the presence and absence of the comma can cause semantic changes. The fourth chapter applies what has been discussed in the previous chapters to English-Chinese translation.

在此基础上，本文第二、三章标新立异，运用语音语调原理、写作、修辞、美学、语义学等方面的知识，通过详实的文献实例，全面地论述了英汉语逗号的修辞和语义功能：从修辞功能的角度看，逗号可以用以进行澄清、解释、替代、强调、对比、补充，或是取得生动和幽默的效果，等等；从语义功能的角度看，逗号本身可以作为信息载体，暗含特定的意思，在更多的情况下，它本身不含意义，但它的使用与否会引起整个句子意思的变化。
