do you think 所带宾语从句的疑问词为何放到主句前

这里的do you think是插入语,还有类似的do you suppose,you know,I suppose,do you believe等.陈述句中,插入语可放在句中、句尾；特殊问句中放在句中,结构为：疑问词+插入语+陈述语序.
而且：
1）Do you think...你认为.的用法：
Do you think 后面不可加 who 这样的问句,只能是加陈述语句,像 Do you think Linda can get this done?Do you think Paul can afford a car?
2）要问 who 得这样用,
Who do you think can get this done?Who do you think can afford a car?do you suppose, do you expect,do youimagine, do you consider,do you believe这些结构的用法是否同do you think 这样用作插入语呢？也就是说后面句子的疑问词是否也都需要放在这些插入语之前呢？谢谢。是啊，这些都一样。。。一般考think和suppose居多。。。但是suppose还有一个其他用法，就是suppose含义会有变化，suppose会出现在虚拟语气中。。。查下suppose的用法，一定要认真区分含义不同时的用法。
