Question

Can you tell me why____yesterday. a.you didnt

a.you didnt come b.didn't you come，到底选哪个？帮我分析一下

Answer 1

【问题答案】选a，但是，答案书写有错误，应该是“a. you didn't come”
【问题分析】Can you tell me why you didn't come yesterday?是一个宾语从句。宾语从句里面用“陈述句语序”。

Answer 2

you didn't come 陈述句语序

didn't you come 疑问句语序

这道题应该填入you didn't come，即：

Can you tell me why you didn't come yesterday. 你能告诉我你昨天为什么没来吗。

由tell sb sth 告诉某人某事 (tell带双宾语)可知：

why引导一个宾语从句，宾语从句用陈述句语序即可。所以填you didn't come。
