为什么要用Do you know what's wrong with him?的语序,却要用Do you know what the answer is?的语序

你的是宾语从句.宾语从句用陈述句语序
1）Do you know what's wrong with him?
这个句子：换个说法Something is wrong with him【陈述句语序】
is 在wrong 前边哦 同例句,陈述句语序
2）Do you know what the answer is
这个句子的陈述句是：The answer is that 【陈述句,is 在主语answer后边】
不用管is在哪里,要清楚是陈述句语序是不是只有what's wrong with him？的what 后用is，其他情况就不这样了？疑问句语序就是一般一般问句在一般情况下，有be 的都在主语之前 如： she is doing homework [陈述句语序] Is she doing homework 【疑问句语序，注意is的位置】 What is she doing？【疑问句语序】但是注意： I know what she is doing 【在宾语从句中便陈述句语序哦】是不是只有在宾语从句中从句的what's wrong with him？的what 后用is，其他情况就不这样了
