You mustn't speak loudly here. = Don't speak loudly here.（这里mustn't 解释为不许、禁止的意思）

★特殊疑问句：

What can you do?

①must表示必须，是主观上觉得应该做，have to是不得不，是由于客观条件逼迫才做

②must只能用在表示现在和将来的句子里，而have to do可以用在任何时态3．must, may, might表示猜测：

①must do 表示对现在事实的猜测

③must have been doing表示对过去正在进行的事实的猜测

may/might do, may/might have done表示没有任何事实依据的猜测，might的可能性更小。can’t/couldn’t表示不可能
