口诀可以总结为：一代二移三倒四抄。
具体来说，就是用正确的疑问词代替划线部分，将疑问词移至句首，颠倒主谓语（但对主语或其定语提问时除外，如some改成any，I改成you，my改成your），然后照抄句子剩余部分。特殊疑问词的确定要根据划线内容而定。在小学阶段常出现的有以下几种：划线部分是“事或物”，特殊疑问词用what。例如：This is a book. ---What is this?划线部分是“人”，特殊疑问词用who。例如：He is my brother. ---Who is he?划线部分是“地点”，特殊疑问词用where。例如：I was born in Beijing. ---Where were you born?划线部分是“时间”，特殊疑问词可以用what time或when。例如：It's 7:30 in the morning. ---What time is it in the morning?划线部分是“年龄”，特殊疑问词用how old。例如：I am 12 years old. ---How old are you?划线部分是“职业”，特殊疑问词用what。例如：My father is a teacher. ---What is your father's job?划线部分是“颜色”，特殊疑问词用what colour。例如：My favorite color is blue. ---What color do you like best?划线部分是“数量”，特殊疑问词可以用how many或how much。例如：I have three apples. ---How many apples do you have?划线部分是“多少钱”，特殊疑问词用how much。例如：This apple costs 10 yuan. ---How much does this apple cost?划线部分是“形容词性物主代词或名词性物主代词”，特殊疑问词用whose。例如：This is my book. ---Whose book is this?
