按理说用前面用的是逗号，而且前面已经有主句了，这里的said应该用saying才对的啊？这里如何理解这个句子结构？
看下面示例：
Tom said that John was an honest man. 间接引语作宾语从句，Tom said这个引述分句作主句。
John was an honest man, Tom said. 间接引语作了主句，Tom said 这个引述分句作为插入语。这种结构称为自由间接引语。
你的这个句子中，逗号后为引述分句作插入语, 逗号前为自由间接引语作主句。整个句子为自由间接引语结构。
另外，过去式为主动意义，及物动词的过去分词为被动意义。你的句子中said显然是主动意义，排除过去分词。
