提供徐广联的一个语法观点，供您参考：

徐广联教授认为，“插入语有时以一般疑问句的形式置于句尾，用问号。”例如：

1 Ask no more questions, do you hear?

2 Computer hacking has become a serious social problem, don't you think?

他的观点可以作为一种理解思路。

赵俊英的插入语部分，也有类似例句：

You don't mind my smoking, I suppose?

此外，对supplement（补充语）的术语解释，似乎也可找到蛛丝马迹。

A term used in CamGEL for parenthetical strings that are not integrated in clause structure, including what are called non-restrictive relative clauses in other frameworks, as well as certain adjuncts and disjuncts.

仅供参考。
