I can't nderstand _ A what does Christmas mean B what Christmas does man C what mean

问题描述:

I can't nderstand _ A what does Christmas mean B what Christmas does man C what mean
C what mean Christmas does D what Christmas means

原题更正为:I can't understand __ .
选:D.what Christmas means
因为宾从中要用陈述句语序.
ABC的语序均为疑问句语序,故不正确.
