A however B whatever C whichever D whenever 6、I like I like ____ in the autumn when the weather is clear and bright. A this B that C it D on 1、解析：C 此题考查宾语从句中关联词的运用。根据语境，宾语从句中to do 后面缺少宾语，而A、B、D选项中的关联词均为副词，不能作宾语，所以应选what。这句话的意思是”计算机只能做你指示它做的事情“。 * * 1、连接代词和连接副词在句中不是疑问词，因而从句中要用陈述语序。 2、连接代词和连接副词在句中充当句子成分；连接词whether，if，as if在从句中不充当句子成分，只起连接作用；连接词that在从句中不充当句子成分，且无含义，常可省略。 3、whether和if的区别：（1）whether和if在引导宾语从句时一般可以通用。（2）后面直接跟or not时，只能用whether。（3）在介词之后引导宾语从句时，只用whether。（4）用if会引起歧义时，用whether：Please let me know if you want to come.请通知我你是否想来/如果你想来请通知我。Please let me know whether you want to come.请通知我你是否能来。（5）其他几种只用whether的情况：引导表语从句、同位语从句和让步状语从句时；引导主语从句置于句首时；后接动词不定式时。 4、what，which，who，when，where，how等与whatever，whichever，whoever，whenever，wherever，however等引导名词性从句的区别：后者引导的名词不含有疑问意义，而前者引导的名词性从句都含有疑问意义。 5、whatever，whichever，whoever，whenever，wherever，however等与no matter what，no matter which，no matter who，no matter when，no matter where，no matter how的区别：前者既可以引导名语性从句，也可以引导让步状语从句，而“no matter + 疑问词”只能引导让步状语从句。 二、主语从句 1、由what，whatever，whoever等引导的主语从句，必须置于谓语动词之前，不能用it作形式主语。 2、由that引导的主语从句，that不充当句子成分，其引导的主语从句，通常用it作形式主语。 三、宾语从句 3、由which，when，where，whether等引导的主语从句，可置于谓语动词前，也可用it作形式主语。特例：如果主句是疑问句，就只能用it作形式主语。如：Hasn’t it been decided yet when and where we’ll hold the sports meeting
