自认是英语高手的进来~！

1.直宾是something, to eat是不定式做后置定语,修饰something ，所以也可以说是something to eat。
2.间宾是one of the...show sth to sb=show sb sth,这样你就能很清楚的看出直宾和间宾了，本句可转化为I showed one of the immigration officers my passport

直宾就是放在谓语后面那个词, to eat是不定式,语法上叫宾补,作用相当于个定语.

my passport 是直接宾语,one of the immigration officers是间接

In fact,这东西没什么用..

1.直宾是something, to eat是后置定语（主语+系动词+宾语+不定式后置定语）
2.中间宾是one of the...(我觉得应该靠换位来判断：I showed one of the immigration officers my passport )

1.（1）直接宾语是something;(2)to eat是something的补语。
2.间接宾语是one of the immigration officers.

我是高手！
