Question

【题目】（题文）I didn't understand_______. So I put up my hand to ask.

A. what my teacher says

B. what did my teacher say

C. what my teacher said

D. what does my teacher say

Answer 1

【答案】C

【解析】

句意：我不理解我的老师说的话，因此我要举手去问。这里考查宾语从句，宾语从句的语序应该是陈述语序，故排除选项BD；因为主句的谓语动词didn't understand是一般过去时，所以从句的谓语动词也应该用一般过去时。故排除A；故选C。
