Tony,你能给我们讲讲你的故事吗？ could表示有礼貌的请求,语气委婉,常用于非熟人之间或晚辈对长辈,下级对上级的场合。 e.g. Could you tell us if it snows in winter in Australia? Sure. 请告诉我们, 澳大利亚冬天下雪吗?当然可以。 提出委婉的请求在回答中不可用could。 - Could I have the television on?- Yes, you can. / No, you cant.2. 在否定、疑问句中表示推测或怀疑。He couldnt be a bad man. 他不大可能是坏人。may和might表示允许或请求;表示没有把握的推测;may 放在句首,表示祝愿。May God bless you!He might be at home.注意: might 表示推测时,不表示时态。只是可能性比may小。have to和must1) 两词都是 “必须”的意思, have to 表示客观的需要, must 表示说话人主观上的看法, 既主观上的必要。 My brother was very ill, so I had to call the doctor in the middle of the night. 我弟弟病得很厉害,我只得半夜里 把医生请来。(客观上需要做这件 事)He said that they must work hard. 他说他们必须努力工作。(主观上 要做这件事)2) have to有人称、数、时态的变化,而must只有一种形式。但must 可用于间接引语中表示过去的必要或义务。He had to look after his sister yesterday.3) 在否定结构中:dont have to 表示 “不必”, mustnt 表示“禁止”。You dont have to tell him about it. 你不一定要把此事告诉他。You mustnt tell him about it. 你一定不要把这件事告诉他。用情态动词can, cant, may, must, mustnt , neednt, could 填空。 1. - _ you come and play with us now? - Im afraid I _.
