解析

【分析】
本题考查“used to do sth(过去常常做某事)”结构的句式转换,需掌握该结构的核心规则:变一般疑问句、否定句、特殊疑问句时,借助助动词did,后接动词原形use;反义疑问句遵循“前肯后否”原则,主语需用代词替代。具体解题思路:1. 改一般疑问句用Did开头,后接use;2. 改否定句用didn't加use;3. 反义疑问句前肯后否,主语用she,故填对应否定结构;4. 对动作提问用What加did;5. 对频率提问用How often加did和use。
【解析】
1. 原句为used to结构的肯定句,变一般疑问句需将助动词did置于句首,used还原为原形use,故填Did; use。
2. 变否定句时,借助助动词did的否定形式didn't,后接动词原形use,故填didn't use。
3. 反义疑问句遵循“前肯后否”规则,前半句主语the little girl用代词she替代,后半句用否定结构,故填didn't she。
4. 画线部分是动作内容,需用疑问词What提问,原句为过去式,借助助动词did,故填What did。
5. 画线部分是频率,需用疑问词How often提问,原句为过去式,借助助动词did,后接动词原形use,故填How often did; use。
【答案】
1. Did; use 2. didn't use 3. didn't she 4. What did 5. How often did; use
