宾补还是状语的判断

请教老师们：

He will have the car at his disposal for the whole month. 

如何剖析好呢？ 

我觉得: have此处为使役动词，at his disposal为宾补，只不过省略了be。而一个同学觉得：at his disposal为状语哪个更好呢？先谢谢老师们帮忙！

这里，have 仍然是一个 “使役动词”。意为：“使某物处于某种状况; 或某种状况” , 可以接副词、形容词、介词短语充当补足语的复合宾语。

作为 “使役动词” have 的使用方法，除去宾补是 “不定式、目前分词、过去分词” 以外，还有上述使用方法。若是副词、形容词、介词短语充当宾补的话，就不可以不再加 be 动词了，这不是省略的问题。道理就是：由于 be 动词本身就表示状况，副词、形容词、介词短语做宾补已经表示状况，这个 be 就不再需要。

关于副词（一般为地址副词）、形容词、介词短语作宾补，举例说明：

Will you have him in? （副词）

I will have some friends over for bridge tomorrow. （副词）

I won’t have David home at present. （副词）

I expect Amy will have the tea ready right now. （形容词）

The long trip had them extremely tired. （形容词）

He had done business with Germans; he had them to his house. （介词短语）

They had this army under his control. （介词短语）

网友的句子，He will have the car at his disposal for the whole month.跟最后两句相同。
