do you have anything to drink中的to drink为什么是定语而不是宾语补足语

do you have anything to drink中的to drink为什么是定语而不是宾语补足语 如何区分宾语补足语和宾语的后置定语 比如说 i have some work to do to do 为什么是work I'm thirsty!Do we have anything to drink? Do you have anything for the baby to drink?非谓语动词主表被 What anything else do you want to drink? 把have,anything,drink,to,you,got组成句子 不定式做定语DO you want something to drink. would you like anything else to drink? Would you like anything to drink Do you like to have cold ___(drink)? 如何区分宾语补足语和宾语的后置定语 比如说 i have some work to do .,不确定答案者勿扰 drink啊可数Do you like to have cold< 这道题目中是填drink还是drinks?
