.I saw her with them,at least,I thought it was her.句子中them是做主语的补足语?

问题描述:

.I saw her with them,at least,I thought it was her.句子中them是做主语的补足语?
百度百科里这么说:
1.I saw her with them,at least,I thought it was her.我看到她和他们在一起,至少,至少我认为是她.(her做宾语,with做介词宾语,them做主语补语)
them是做主语补语的么?

her做宾语,with是介词,them是介词的宾语,不是主语补语.with them合起来是一个介词短语介词短语with them是做补语么?恩,是做补语,不过不是主语补语,是her的补语,也就是宾语补足语
