新概念三冊32課的課文: A radio message from the mainland had been received by the ship's captain instructing him to give up the search..這里的instructing 是作狀語還是主補?

是主補A radio message （which/that instructed）instructing him to give up the search from the mainland had been received by the ship's captain.

我認為instructing him to give up the search 是分隔性定語，修飾主語a radio message,用來說明主語的內容，而不是主語補足語或狀語

熱心網友

我認為是主補，顯然instructing...是a radio message的內容.

A radio message from the mainland had been received by the ship's captain instructing him to give up the search..這里的instructing 是作狀語還是主補?理解成定語或同位語才對：變化原句成：A radio message （which/that instructed）instructing him to give up the searchfrom the mainland had been received by the ship's captain ..

修飾動詞的才是狀語，這里instructing him to give up the search是補充說明主語A radio message 的，因此是主補。

補語。是radio message的內容嘛。
