(1)must表示“必须”或“应当”，其否定式为mustn't。
以must开头的一般疑问句的肯定回答为：Yes, 主语＋must;

▲
4. have to 的用法
(1) have to 的意思是“必须、不得不”, 往往强调由于客观原因而必须做某事。have (has) to 后面要用动词原形。当主语为第三人称单数时用 has to，当句子是过去时用 had to。如：
He has to work on Sunday. 他不得不在周日工作。
(2) have to 的否定句句型：主语 + don’t / didn’t / doesn’t / won’t + have to + 动词原形。如：

肯定答语：Yes, he / she / they can.
否定答语：No, he / she / they can’t. 或No, he / she is / they are not available.等。
