You could start a fire. 在林子里走时勿吸烟，那样可能会引起火灾。 3）表示允许。 Can I have a look at your new pen? 我可以看一看你的新钢笔吗？ He asked whether he could take the book out of the reading-room. 他问他可不可以把书带出阅览室。 4）表惊异、怀疑、不相信等态度。主要用于否定句、疑问句或感叹句中。 Where can (could) they have gone to? 他们会去哪儿了呢？ He can’t (couldn’t) be over sixty. 他不可能超过六十岁。 How can you be so careless? 你怎么这么粗心？ 5）比较委婉客气地提出问题或陈述看法。 Can (Could) you lend me a hand? 帮我一把好吗？ I’m afraid we couldn’t give you an answer today. 恐怕我们今天不能给你答复。2. may (might) 1）表允许，might可以指过去时间，也可指现在时间，语气更委婉。 You may take whatever you like. 你喜欢什么就拿什么。 He told me that I might smoke in the room. 他告诉我可以在房间里抽烟。 May (Might) I ask for photo your baby? 我可以要一张你宝宝的照片吗？ 在回答以may引起的问句时，多避免用这个词，而用其它方式，如Yes, please. / Certainly.
情态动词must用法详解
情态动词must用法详解 (1) 表示“必须” 此时可用于肯定句、否定句或疑问句，用于否定句时，mustn’t的意思是“一定不要”“不能”，而不表示“不必”。如： Water must be pure if it is to be drunk. 水如供饮用必须净化。 Must I finish the work tonight? 我必须今晚完成这项工作吗? Adverbs mustn’t be put between the verb and the object. 副词不能放在动词和宾语之间。 must主要表示现在或将来，但在间接引语中也可表过去(=had to)。如： She asked her boss if she must (had to) work overtime. 她请示上司她是否要加班。 对于must开头的一般疑问句，若作否定回答，可以用needn’t，不能用mustn’t。如：“Must I clean all the rooms?” “No, you needn’t.” “这些房间我都得清扫吗?”“不必。” (2) 表示推测 意为“准是”“一定是”，通常只用于肯定句。若用于否定句或疑问句，则用can 代之。如： That can’t be the only way. There must be other ways of solving the problem. 那不可能是解决问题的唯一办法，肯定有另外的办法。 Jane’s light is on. She must be at home. She can’t be out. 简的房间里开着灯。她一定在家，不会出去的。 若要谈论过去或完成的情况，必须用“must+have+过去分词”。如： You must have mistaken my intention. 你一定是误会了我的意图。 She must have been very young when she got married. 她结婚时一定很年轻。 He must have come this way; here are his footprints. 他一定是走这条路来的，这里还有他的脚印呢。 They must have finished their homework, for they are playing happily on the playground. 他们一定是写完作业了，他们在操场上玩得多开心呢。 (3) 表示“偏偏” 有时must可表示某事发生得不早不迟，就在某个当紧的时候，多指某些不受欢迎的事情的发生。如： The car must break down just we were starting our holidays. 我们刚刚开始休假，汽车偏偏坏了。 Must you worry her with questions, just when she is busy cooking dinner? 她正忙着做饭你干吗偏偏问她问题? Just when I was busy, the neighbor must come and chatter. 正当我忙碌的时候，邻居偏偏过来聊天。 有时还可指主观上的偏执或固执，常可译为“偏”“偏要”。如： After I gave her my advice，she must go and do the opposite. 在我给她出主意之后她偏要反着干。 Must you make so much noise? 你就非得弄出这么大的声音吗？ (4) must 与have to 的区别 两者都表示“必须”，但must 侧重于说话者的主观看法，认为有必要或有义务去做某事；have to 则重于客观需要，含有“不得不”“被迫”之意。如： Everyone must keep the law. 人人都要守法。 The last train has gone. We’ll have to walk home. 最后一班车已经开了，我们得走回家了。
