如果原句里用的是联系动词,即常见的be,那么变一般疑问句就把be提到句首 如：He is a student.----Is he a student? 如果原句里用的是实义动词（有实际意义的动词）如：like,study,learn,go,make,buy,catch,finish...,那么变一般疑问句就在句首加do 或does(如果是一般现在时态） 如：He likes to skate.----Does he like( 此时变成原形）to skate? I go to school by bus.---Do you go to school by bus? 希望我真诚的回答能让你满意!
