C

试题分析：考查主语从句。本题的what引导的是一个主语从句，what在句中做主语。句意：猪肉的价格没有像预料的那样被控制，在过去的几个月里猪肉的价格出人意料第上涨了百分之15.故C正确。It不能引导主语从句，that在主语从句不充当任何成分。Which是指特定范围之内的某一个。故C正确。
点评：名词性从句的考查集中在引导词的选择上，连接词that, whether, if在句中不充当任何成分，只起连接作用；连接代词who(ever), which(ever), whom(ever),whose(ever),what(ever)在句中做主语，宾语，表语和定语；连接副词when, why, where, how，在句中做状语。应从上下句的句法关系着手分析，切不可‘望句形生答案’总的来说，考生在解答此类型时，可用排除法或造句法，造句法就是仿造原句的语法功能仿造出一个易懂易理解的句子，帮助判断。
