what's the meaning 后接句子如何造句

问题描述:

what's the meaning 后接句子如何造句
我知道what's the meaning of 的说法,但这个后面是接名词,如果要接句子,怎么说?例如:当你头痛的时候意味着什么?将What does it meat when you have a headache?改写成What's the meaning.的句式.怎么改?

what's the meaning of 后接名词,不能接句子
直接说成what's the meaning of headache?
或者加从句:what's the meaning of it when you have a headache?
