Question

I didn’t understand ________ so I raised my hand to ask.

A. what my teacher says

B. what does my teacher say

C. what my teacher said

D. what did my teacher say

Answer

C

【解析】

试题分析：句意：我不理解老师说的话，所以我举手提问。宾语从句的结构：主语+谓语+连接词+从句。从句在句中作宾语。从句要用陈述句的语序。如果主句是一般现在时，从句根据需要选择时态，如果主句是过去时态，从句要用相应的过去时态。但是从句是客观真理，一般用一般现在时态。所以答案选C。

考点：考查宾语从句用法。
