He might/may be at home. might 表示推测时，不表示时态， 只是可能性比may小。 have to 和 must My brother was very ill, so I had to call the doctor in the middle of the night. He said that they must work hard. He had to look after his sister yesterday. ① “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， 即主观的必要。 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。 ③ 在否定结构中: don’t have to 表示 “不必”，mustn’t 表示“禁止”。 You don’t have to tell him about it.　 You mustn’t tell him about it. 用情态动词can/could, can’t, may, must, mustn’t, don’t have to填空。 1、 — _______ you come and play with us now?   — I’m afraid I _______.
