EG:ought to not 还是ought not to 这种问题是否有规律

这样说吧,把这个当成是动词不定式,动词不定式的否定形式是在to前面直接加not,记住即可
应该是ought not to没有to not的用法，只有把not 放到前面。你记住就好了 ought to的用法 1）ought to ＋动词原形 （1）表示义务、责任或劝告，可译为“应该”。 You ought to（＝should）obey your parents．你应该听你父母的话。We ought to（＝should）love others as ourselves．我们应该爱人如己。（2）表示“推测”，指根据道理或事实所推理出来的结论，可译为“照道理讲应该”。He ought to（＝should）be able to speak English after studying it so long．他在学习这么久之后，照道理讲应该会说英语。If he started at nine，he ought to（＝should）be here by four．既然他是九点钟动身的，最迟到四点钟就应该到达这里。2）ought to ＋不定式的进行时，肯定句中表示主语没有做他该做的事；否定句中表示主语正在做他不该做的事。He ought to be studying for his exam．He shouldn't be spending all his time on the beach．他应该正在为他的考试作准备。他不应该把时间都消磨在海滩上。I ought not to（＝shouldn't）telling you this．It's supposed to bea secret．我不应该告诉你。这应该是个秘密。3）ought to ＋不定式的完成时，肯定句中表示主语过去该做而未做的事，否定句中表示主语过去做了不该做的事情。You ought to（＝should）have been more careful（but you were not careful enough）．你应该更小心的。You oughtn't to（＝shouldn't）have crossed the road when the lights were red．红灯亮的时候，你就不应该穿越马路。否定形式为 ought not to没有to not的用法，只有把not 放到前面。你记住就好了 ought to的用法 1）ought to ＋动词原形 （1）表示义务、责任或劝告，可译为“应该”。 You ought to（＝should）obey your parents．你应该听你父母的话。We ought to（＝should）love others as ourselves．我们应该爱人如己。（2）表示“推测”，指根据道理或事实所推理出来的结论，可译为“照道理讲应该”。He ought to（＝should）be able to speak English after studying it so long．他在学习这么久之后，照道理讲应该会说英语。If he started at nine，he ought to（＝should）be here by four．既然他是九点钟动身的，最迟到四点钟就应该到达这里。2）ought to ＋不定式的进行时，肯定句中表示主语没有做他该做的事；否定句中表示主语正在做他不该做的事。He ought to be studying for his exam．He shouldn't be spending all his time on the beach．他应该正在为他的考试作准备。他不应该把时间都消磨在海滩上。I ought not to（＝shouldn't）telling you this．It's supposed to bea secret．我不应该告诉你。这应该是个秘密。3）ought to ＋不定式的完成时，肯定句中表示主语过去该做而未做的事，否定句中表示主语过去做了不该做的事情。You ought to（＝should）have been more careful（but you were not careful enough）．你应该更小心的。You oughtn't to（＝shouldn't）have crossed the road when the lights were red．红灯亮的时候，你就不应该穿越马路。否定形式为 ought not to没有to not的用法，只有把not 放到前面。你记住就好了 ought to的用法 1）ought to ＋动词原形 （1）表示义务、责任或劝告，可译为“应该”。 You ought to（＝should）obey your parents．你应该听你父母的话。We ought to（＝should）love others as ourselves．我们应该爱人如己。（2）表示“推测”，指根据道理或事实所推理出来的结论，可译为“照道理讲应该”。He ought to（＝should）be able to speak English after studying it so long．他在学习这么久之后，照道理讲应该会说英语。If he started at nine，he ought to（＝should）be here by four．既然他是九点钟动身的，最迟到四点钟就应该到达这里。2）ought to ＋不定式的进行时，肯定句中表示主语没有做他该做的事；否定句中表示主语正在做他不该做的事。He ought to be studying for his exam．He shouldn't be spending all his time on the beach．他应该正在为他的考试作准备。他不应该把时间都消磨在海滩上。I ought not to（＝shouldn't）telling you this．It's supposed to bea secret．我不应该告诉你。这应该是个秘密。3）ought to ＋不定式的完成时，肯定句中表示主语过去该做而未做的事，否定句中表示主语过去做了不该做的事情。You ought to（＝should）have been more careful（but you were not careful enough）．你应该更小心的。You oughtn't to（＝shouldn't）have crossed the road when the lights were red．红灯亮的时候，你就不应该穿越马路。否定形式为 ought not to
