被动句改特殊疑问句,对划线部分提问.挺急的.
如题,Students should be taught how to manage their own lives by their parents.
划线部分their parents,求填空____ ____ ____students ____ ____how to manage their own lives?

正确答案为：
By who should be taught为什么开头是by……？难道不是who吗TT~TT，后面能明白但前面不明白……因为原句是被动语态，students should be taught........by.....
画线又是 their parents, 说明提问的是 by who 所以开头是 by
