Some children want to challenge themselves by learning a language different from _____ their parents speak at home.

A．what

B．that

C．which

D．one

答案

A

解析

试题分析：考查宾语从句。本题中的what引导的是一个宾语从句what their parents speak at home作为介词from的宾语，what在句中作为动词speak的宾语。句意：一些孩子想要挑战自己去学一种与父母在家里所讲的不一样的语言。One不能引导宾语从句，that不能在宾语从句中做成分；which是指特定范围之内的某一个。故A正确。
点评：宾语从句属于名词性从句一种，名词性从句分为主语、宾语、表语、同位语从句四种，除宾语从句外，同位语从句和定语从句的区别是高考常考点。宾语从句中的连接词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，考生在解答此类题型时，可用排除法，造句法或者还原法，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。
