Question

______ nearly all behavior is learned behavior is a basic assumption ______ has been put forward by the social scientists.

A．What, that

B．That, what

C．What, what

D．That, that

Answer 1

D

试题分析：考查名词从句的引导词。第一空that引导的是一个主语从句,that在句中不充当任何成分，只起连接作用。第二空that引导同位语从句，对名词a basic assumption进行补充说明。That同样在句中不充当任何成分，只起连接的作用。故D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。
