We feel much honored to have you come to visit our country这句

结构分析如下：
We feel much honored to have you come to visit our country.
主语 系动词 表语 不定式短语当副词用修饰形容词honored做状语
意思是：能让你来参观我们的国家（而荣幸）
是解释表语“因什么而荣幸”的
在不定式短语 to have you come to visit our country中：
you是动词have的宾语；come是动词原形作宾语补足语；
to visit our country不定式短语作副词用,作come的目的状语.
