在外研初中英语初三下册有如此的一个句子：Where do you think is the best place to keep food safe from bears? 根据混合疑问句的特征，where不作主语，所将来面应该用陈述句语序Where do you think the best place to keep food safe from bears is? 是教程的句子出错了吗？
有老师说这里的do you think是插入语，若是插入语那样麦克米伦词典上的Who do you think you are?为何用的又是陈述句语序？求大神指点。
在 Where do you think 后面应该用陈述句语序。比如： Where do you think we should eat ? 你觉得大家该到哪里吃饭？（摘自《韦氏高阶英汉双解词典》p.2184）
do you think 不可以作为插入语。所以，“Where do you think is the best place to keep food safe from bears?”应该改为：
Where do you think the best place to keep food safe from bears is?
