基本原则:前肯后否,前否后肯。
例:He is a teacher,isn't he?
He isn't a teacher, is he?
They can swim, can't they?
He doesn't like it ,does he?
助动词或be动词提前,动词变为原形,注意人称不同,助动词也不同
反义疑问句是在陈述句后依据句子的谓语形式构建一个简单的一般疑问句形式(需符合前肯后否的原则)。例如,He is your boss,isn't he?
be否定 加主语,如钱面有否定词,后面值接be加主语(原型)
还有,let
let‘s sth to sb
sth:(什么)事。
sb:( 谁 )人。
