An object complement is a noun, a pronoun, or an adjective that follows a direct object to rename it or state what it has become. 所以宾补本来就是定语,比如you make me happy. 但并非所以定语都是宾补。必须 to rename it or state what it has become.
I have sth to do 意思是I have sth that I should do 所以to do 是定语 如果是 have her call me 意思是 tell her to call me 不定式to call me 做补语 定语在句型分析时,不是句子的必要成分,比如第一句是主谓宾 补语是必要成分,第二句是主谓宾宾补
