Mdal verbs: can and cannt, may and may nt, must and must nt
Mdal verbs can be used t talk abut ability, permissin, bligatin, etc.Daisy is telling her brther Benny abut her science lessn. Read their dialgue and pay attentin t the wrds in bld.
Benny: Hw was yur schl day, Daisy?Daisy: It was great. We learnt abut electricity in ur science class.Benny: Can yu tell me what yu knw abut electricity?Daisy: We can't see it pwering everyday things but we can see it when there is a lightning strm.Benny: Right. Mum tld me we mustn't g utdrs during a strm. It’s dangerus.Daisy: Yes, that's right. Hwever, yu can prduce electricity safely by rubbing a ruler against yur sweater. Lk at me!Benny: Ww. That’s fun! May I try?Daisy: Yes, f curse. But yu must give it back t me because it's my favurite ruler!
After mdal verbs such as can, may and must, we use the base frm f a verb. We use can and cannt (can’t) t say we are able r unable t d smething. We use may and may nt t ask fr, give and refuse permissin. In less frmal situatins, sme peple like t use can and cannt (can’t)fr the same purpse. We use must and must nt (mustn’t ) t tell peple what t d r what nt t d.
• 在 can、may、must 等 情态动词之后，动词用原形。• 用 can 和 cannt ( can't) 表示能或不能做某事。• 用 may 和 may nt 来 请求、给予或拒绝许 可。在不太正式的情 况下， 也可以用can和 cannt ( can't)来表示 同样的目的。•用 must 和 must nt (mustn't)来告诉人们 该做什么或禁止做什 么。
can ① be able t “能”，表示能力 I can/am able t sing an English sng.我可以唱一首英语歌曲。②表示许可或请求对方允许，意为“可以” Can I use yur dictinary? 我可以用你的字典吗？③ 过去式：culd 我十年前就能做到那样. I culd d that 10 years ag.④否定式： cannt = can’t
⑤culd 是can 的过去式，但表示请求许可时，culd 和can 不表示时态的区别，只是culd 的语气更加委婉，用culd 提出的请求要用can来回答。
Peter can speak English.否定→ Peter can’t/cannt speak English.一般疑问句→Can Peter speak English? (一般疑问句，提前情态动词)特殊疑问句→What can Peter speak?
may ①表示允许may 表示许可或请求对方允许，意为“可以”，相当于can。两者的区别在于：表示请求许可时，may更能表示礼貌或敬意。 — May I watch TV nw, grandma? — N, yu may nt.
②否定式： may nt意为“不可以”。③may构成的一般疑问句及其回答形式如下： — May I — (肯定回答) Yes, yu may / can.— (否定回答) N, yu may nt / can’t /mustn’t. (注：mustn’t 的语气最强，表示禁止)
情态动词must的用法
must ①表示规定、命令、强制，意为“必须；一定”。如：Yu must d yur hmewrk first. 你必须先做作业。 Yu mustn’t smke here. 你不许在这里吸烟。②must 的否定式为must nt / mustn’t，意为“禁止；不准”③must 构成的一般疑问句及其回答形式如下：— Must I — (肯定回答) Yes, yu must.— (否定回答) N, yu needn’t.
