what did you say just now? i asked

问题描述:

what did you say just now? i asked
A.how can I open the door.
B.if you watch TV last night.
C.when did the program start.
D.you had finsh you homework
为什么选B,A C D哪里错了?
选B,这段对话什么意思?

ACD语序错误:宾语从句应使用陈述句语序——主语在前、谓语动词在后
B if引导宾从意为是否——昨晚你是否看电视了
但此题B选项存在时态错误,谓语动词应改为过去式.
