Ought he to go to England with Tom?ought to do sth.应该做某事 = should do sth.should变疑问句放句首,ought也一样.陈述句：He ought to go to England with Tom.-> 疑问句：Ought he to go to England with Tom?...用反义疑问句也是在句末加，ought he或，oughtn’t he吗？用shouldn't / oughtn't +主语都可以情态动词的反义疑问句的用法是什么呢 哪些要加助动词 哪些直接用情态动词你这追问已超出范围，烦请另开一个问题，谢谢!
