在International Journal of Polymer Science上投了一篇文章，今天给了回复，其中有个修改意见：
In addition, I found that references [1-9] and [15-21] have been concentrated in the introduction section. As you know, all references
that are included in a manuscript are supposed to contribute to the scholarly content of the article, and every single reference has to be
properly referred to within the text.
Please rephrase the citation of these references within the text, and update the references list accordingly.
