I think that their behaving poorly can be explained by the following reasons.这句话有语法错误吗？

Question

如题所述

Answer 1

你好！

I think that their behaving poorly can be explained by the following reasons。

我个人觉得有点小问题，这儿的poorly用的不合适。

它不能搁在主语和情态助动词中间。

虽说这儿的behaving是动名词，但作为从句的主语，基本是名词性质，所以用形容词poor更恰当。

建议更改如下。

I think that their poor behaving can be explained by the following reasons。
