宾语与宾补之间存在逻辑上的主谓关系。即宾语和宾补是描述和被描述的关系。所以宾语改为主格，宾补之前加上一个适当形式的be, 或将宾补的非限定形式改为限定形式就可以改写成一个句子。

例如：

He made me mad. —— I was mad.

I want him to come. —— He is to come/will come.

I call him brother —— He is (a) brother.

I saw him come in. —— He came in.

I caught him stealing. —— He was stealing.

网友以上三个词例中，宾语和其后的三个介词短语之间并不存在这种逻辑主谓关系。宾语和介词短语也无法通过+be改写成一个句子。所以以上介词短语都是动词的状语，而不是宾补。网友对宾补的认识是错误的，已经不止一次误将状语视作宾补，应该引起重视了。
