be 动词一般疑问句的变化规则
秘诀：一提二改三问号 一调：即把句中的be提到主语前；
二改：改换主语称谓，即将句中的主 语I my mine we our ours等第一人称分别 改为相应的第二人称you your yours等；
三问号：句末的句号改为问号
1、大多数动词在词尾直接加s， 如read → reads look→ looks jump ---jumps play→ plays 2、以辅音字母加y结尾的动词，要先将y变为i，再 加es 如：fly →flies carry →carries study →studies 3以“s, x, ch, sh”结尾的，在词尾加“es”发音为 [iz] 如：teach－teaches ; watch－watches 4、以“o”结尾的动词，加“es”，读[z] 如: go－goes do－does 5.不规则变化： have----has
