Paws prints were seen in a number of places and puma fur was found 【clinging to bushes】

Howener,he had at last been allowed 【to sen a fax 】in whinc he informed the editor that he had been arrested while counting the 1084 steps leading to the fifteen-foot wall which surrounded the president's palace.
括号里的是主补.
那是怎么看出来的?什么是主补?
主补是出现在主谓宾结构还是出现在主系表结构?

Answer 1

宾补时对宾语的补充说明,主补那就是对主语的补充说明.当原句中宾语作主语后（句子要变成被动语态）,原来的宾补就成了主补了.
没有补语句子的主干成分（主谓宾）齐全,但无法完整表述意思.
主补应该是出现在主谓宾结构中,确切的说应该是被动句中.主系表结构不会有主补.
