1.do you think的确是插入语,而且此类插入语是放在疑问词之后,且其后的句子必须改用陈述句语序,而不是倒装语序（疑问句语序）,原因是因为do you think这种插入语已经倒装了.
如：Where do they live?他们住在哪里?
Where do you think they live?你认为他们住在哪里?
2.此句除了插入语do you think之外,剩下成分是强调句型的特殊疑问句（以what引导）.
强调句原句是：What is it that makes english version of the musical norye dame de paris different from the previous ones?
what提前至句首后,再加上插入语do you think,后面就改用陈述句序为：it is (what) that makes english version of the musical norye dame de paris different from the previous ones.
3.it is...that...是强调句型的结构要求,剩下结构为：
What makes english version of the musical norye dame de paris different from the previous ones?
句中,what是主语,makes是谓语,english version of the musical norye dame de paris是宾语,其后的短语different from the previous ones为宾语补足语.
其中含有一个“使役动词make + 宾语 + 宾语补足语”结构.
该句话强调的就是句子的主语what.
