He asked whether he could take the book out of the reading-room. 4）表示对现在动作或状态的猜测，主要用于否定句和疑问句中或感叹句中: He can’t (couldn’t) be over sixty.他不可能超过六十岁。 5）could表示比can更委婉客气的提出问题或陈述看法，指的是现在时间。 Can (Could) you lend me a hand? 帮我一把好吗？ 2. may (might) 1）表允许，询问或说明一件事可不可以做，might指过去时间；但在疑问句中might也可指现在时间，语气比may更委婉。 May (Might) I ask for a photo of 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，肯定回答是一般可仍用may,或Yes, please. / Certainly./Sure./Of course. ； 否定回答根据说话人的语气由强到弱分别选用: must not(mustn’t)（禁止）/ had better not（最好别）/ may not（不行） 2) may表可能,但所表示的可能性不如can所表示的那样肯定。might可以指过去时间，也可以指现在时间，但语气更加不肯定。 He may be at home. 他可能在家。 They might be having a meeting, but I’m not sure.他们有可能在开会，不过我不肯定。 3. must（have to表示客观需要） 1）表示“必须”（主观看法）时，用于肯定句或疑问句；用于否定句时表示“禁止”。 We must do everything step by step. 我们一切都必须循序渐进地做。 You must get home before 9:00. 2）表示揣测。意为“想必、准是、一定”等，只用于肯定句。 He must be ill.
