答案：C

题目分析：句意：它不像她许诺我们的一顿美餐。这里是定语从句，先行词是dinner，因为有such修饰先行词所以用as，它在从句中状语。故选C。

点评：本题难度适中。

即学即练：He has lots of friends, only a few of  ______ invited to his wedding.

A. whom       B. them       C. which       D. who

解析：B。考查定语从句和其他结构的区别。only a few of them invited to his wedding是独立主格结构，此结构不是完整句子，因此不能选其他引导词。
