【本讲教育信息】一、教学内容必修3 Unit 2 Modal verbs (2) 情态动词（2）ought to / ought not to /have to / don‘t have to / mustn‘t /need/needn‘t / 情态动词+ have done二、知识精讲（一）ought to／ought not toought to意为“应该，应当”，是情态动词，没有人称和时态的变化，与should同义，语气较强。
例：You ought to obey your parents.你应该听父母的话。
You oughtn‘t／ought not to blame him.你不应该责备他。
