Question

请问句子48中（3）里面的that后面为什么加逗号？

Answer 1

that he had no power of reasoning 是一个定语从句，因为中间插入了一个让步状语-while he was a good observer-所以前后用逗号隔开。

追问

您好，while引导的那个从句是让步状语从句。

追答

哦，抱歉。

已改正。

Answer 2

...因为that he had no power of reasoning,中间插入了while he was a good observer,让步状语从句 ，所以加一个逗号 在 that后。以便把两个连接词that/while区别开，以免混淆理解。

Answer 3

因为中间有个插入的让步状语从句，while he was a good observer。用逗号隔开后，连接词that与从句 he has no power of reasoning的关系就非常清晰。
