题目内容
13.A computer can only do ________ you have instructed it to do.( )A. | how | B. | after | C. | what | D. | when |
分析 计算机只能做你指示它做的事情.
解答 C 考查宾语从句.分析提干信息可知you have instructed it to do是动词do的宾语从句,宾语从句中to do没有宾语,连接词应该用what引导,what在从句中做do的宾语,所以答案选C.
点评 宾语从句属于名词性从句中的一种,也是学生们需要掌握的一种基本的英语句型,引导名词性从句的连接词选择是考试的重点,学会分析从句的句子成分是解决名词性从句的解题关键.
