have got to 和have to 在意思上基本相同,表示 不得不, 后面都是加动词原形
但在句式变化上是不同的
have got to 在变疑问和否定时,是在have上发生变化的,
have to 在变疑问和否定时,需要用助动词do
如 He has got to buy the food by himself
变否定:He hasn't got to buy the food by himself
变疑问: Has he got to buy the food by himself?
He has to buy the food by himself.
变否定: He doesn't have to buy the food by himself.
变疑问: Does he have to buy the food by himself.本回答被提问者和网友采纳
