情态动词本义（may+might+must）知识点总结-2022届新高考英语语法微专题培优复习

2022届新高考英语语法微专题培优复习 英语语法：情态动词本义（may might must）知识点总结 may / might  语气最弱，强调不确定的情况或较弱的可能性 / 表示许可 must  语气最强，态度非常坚决、情况非常确定、语气非常绝对 For the engine to work, the green button must be in the "on" position. 强调绝对的必要性。绿色按钮必须在on的位置上。 If you must bring children with you, plan ahead and bring something for them to play with. 强调绝对的必要性。如果你非要带孩子来。注意句中通过must体现的语气“非要……”。如果换成will描述意愿，在这里就无法体现“必要”的语气了。 - The traffic is heavy now, so Mike might come late. - Let's wait ten more minutes. 描述也许有可能发生的情况。迈克也许会迟到。may和might两个形式在描述可能性的时候可以视作同义词，只是might的语气更弱一些。 Lifting off at sunrise, the hot air balloon goes wherever the wind may blow. 描述不确定的状况。无论风吹向何处。风的方向是不确定的。 - Why are those people gathering in the middle of the street? - I don't know.

I've got an appointment with Miss Smith in the Personnel Department. - Ah, good morning. You must be Mrs. Peters. 描述非常确定自信的判断。你一定是彼得夫人。注意第一个人提到自己有预约，所以语气很确定。 - I don't really like James.
