C解析试题分析：考查名词性从句的连接词。第一空what he wants to say是一个主语从句，what引导起这个主语从句，并在句中作为say的宾语；第二空是有how引导的表语从句how great an effort he has made to help her out. 其中的How修饰great.句意：他想说的是，他花了多大的努力才帮助她摆脱了困境。故C正确。考点：考查名词性从句的连接词点评：what引导名词性从句，在句中做主语，宾语，表语；这些连接代词在句中通常做主语，宾语，表语；连接副词when, where, why, how在句中做状语。连接词whether, if/that在句中不充当任何成分。
