试题分析：考查主语从句的定语从句。本题第一空是what引导的主语从句what is surprising to us,what在句中做主语。第二空是一个定语从句，whom指代Tom作为介词for的宾语。句意：让我们惊讶的是Tom能够讲流利的英语就好像是他的母语一样。，对他来说英语曾经很乏味。故A正确。
点评：任何一个从句的考查都主要考查的是连接词，定语从句的考查主要就是考查关系词的辨析，关系代词that, which, whose, whom, as， who在句中做主语，宾语，表语或者定语；where, why, how在句中做状语。要分析句子成分，看缺少什么成分，就选用相应的关系词。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。
