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!
如she
is
a
student
这样主语后面是be动词的陈述句,改为一般疑问句就只用把be动词提前,改为is
she
a
student?如果是she
has
a
bag这样主语后面不是be动词的句子,改成一般疑问句就在主语前面加上do或does.如does
she
have
a
bag?
不懂的可以追问。
