she used to spend all her pocket money on food.（改为一般疑问句）
问题描述：
she used to spend all her pocket money on food.（改为一般疑问句）
答案是used she to spend all her pocket money on food?
难道used也可以做疑问句引导词吗?我一直以为只有w开头和how能做疑问句引导词..
答
used to 的特殊用法里面是可以这么用的,但是不是很书面的用法
eg：在疑问句、否定句或强调句中,可以有两种形式：
Used you to go to work by bike?
Did you use to go to work by bike?你过去常骑车上班
