句子内容分析
请问曹老师，句子：
He was sure there were lots of people called potter who had a son called Harry. Come to think of it, he wasn't even sure his nephew was called Harry. … There was no point in worrying his wife, …
问题：
1. He was sure (that)+从句、I'm glad (that)+从句等，这类主系表结构中的形容词后加的从句，具体是哪类从句？按现代语法是补足语从句吗？
2. come to think of it具体做什么句子成分，也算评注类状语（表对自己说的话的注释）吗？且为什么come用的是动词原型，此处come不是非谓语动词吗？
3. there was no point in worrying his wife.这句：
（1）in介词短语是做定语，还是状语，感觉是都可以，应该还是自己的逻辑分析不到位？
（2）句中的no是限定词吗，如何理解no+名词的这种用法？

1 表语形容词后接that从句，这个that从句究竟是什么从句，有不同的解释。传统语法中有认为that从句是状语从句，有认为that从句是形容词的宾语从句。现代语法认为that从句是表语形容词的补足语。我目前按照现代语法的观点分析。that从句是解释形容词的，使形容词的语义完整。
2 come to think of it 为固定习语，作评注性状语，表示说话人突然意识到或者想起后面的句子的内容。Come 的逻辑主语为说话人。
the freedictionary: come to think of it
A set phrase used when one has had a sudden realization.
Yeah, come to think of it, Dave was at the party, too.
I know a faster route we can take, come to think of it.
3 in doing sth 分析为point的定语为宜，做某事的意义。no+名词中，no为中位限定词。no = not any （any 为中位限定词）。no+名词，为名词否定句。I don't speak any English. I speak no English. 名词否定句的否定意味更为强烈一些。
