【英语问题】So involved with their computers do the children becom

这是一个倒装结构,强调so 引导的从句,所以助动词前移：So involved with their computers do the children become,原句是：The children become so involved with their computers that leaders at summer computer camps often have to force them to break for sports and games.
再问： 原题要在become the children和do the children become里面选一个，become the children语法上没有错误是吗？
