The retired workers were invited to the company,          surprise,changes had been so great over the years.

A．whose

B．who

C．to whom

D．to whose

答案

D

解析

考查介词加关系代词引导的定语从句。让某人惊讶的是，用to one’s surprise结构，排除A,B；先行词是workers，在定语从句        surprise,changes had been so great over the years.中作名词surprise的定语，要用whose修饰，所以选D。
