Can game not availablemust godoctorfriends Can go moviesfree might have to 用can打听第三方是否能参加聚会，表示一种可能性。用can发出邀请接受邀请拒绝邀请说明理由Observe 情态动词 can用法1. can 表示能力，表示“能，会”。 eg. She can play the piano.2. can 表示许可，表示“可以”。相当于may（比may更口语化）；此外，could的语气更为委婉。 eg. May I come in? Could you help me?can表示邀请时常用一般疑问句句式，结构为:Can+ 主语+ 动词原形+ 其他？ can表示邀请的用法How do we accept or refuse an invitation?(1) 常见表示接受邀请的回答：① Sure, I’d love to. ② Yes, I’d love to.③ Sure. That sounds great.can表示邀请时，其回答分为两类。一类是表示接受邀请，另一类是表示拒绝邀请。(2) 常见表示拒绝邀请的回答：① Sorry. I’m not available.② I’m sorry. I’m not free this weekend. I have to ...③ I’d love to, but I’m afraid I can’t. I have to...拓展--其他情态动词1. must/have to的用法(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; 其否定回答为：No, 主语＋ needn't.eg. --Must I finish my schoolwork today? 我今天必须完成我的功课吗？ --No, you needn’t. 不，你不需要。(2)have to也表示“必须，不得不”。一般情况下，must表示说话人的主观看法，而have to 表示客观需要。(3) 注意： must还可以表示推测 ，“一定” eg. It must be delicious. 它一定很好吃▲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：You don’t have to walk so fast. 你不必走那么快。▲4. have to 的用法(3) have to 的疑问句句型：Do / Does / Did / Will + 主语 + have to + 动词原形。如：— Did he have to ask the question? —他非要问那个问题吗？— Yes, he did. —是的。— No, he didn’t (have to). —不。▲5. must 与 have to【拓展】表示同意邀请的回答还可用：Yes, I’d love/like to. Sure, it sounds great. Certainly, I’d love/like to. Sure, I’d love/like to. Thanks for your invitation. Thanks for asking me. 如果拒绝邀请，答语可用：I’m sorry. I’m not free/available. Thanks for your invitation. I might have to/must...Sorry, I’m afraid not. I might have to/must...Sorry, I can’t. I might have to/must...I’d love to, but I have to… No, I can’t. I’m going to ... Thank you for asking me. But .... I am afraid not, I... 【拓展】其他提出邀请的句型：Could/ Will you…?Would you like to ...?How/ What about ...?Why not ...?Let’s ...I hope you ...can表示“做某事的可能性”，意为“可以”(可用来询问打听第三方能否参加某项活动)。对这种情况下can引起的问句仍由can或can’t作肯定或否定回答。如课本中的句子Can he go to the party?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。can表示可能性—Can Alice go to the movies with us tonight?—Yes, she can. / No, she’s not available. She has to look after her sister. e.g. —Can he come here before nine tomorrow morning? —No, he can’t. He has to go to the music club first. They might have to meet their friends.might在此表示推测和可能性。它的可能性比may小。情态动词might用法e.g. She might not want to come with us. 她可能不想和我们一起走。How long might the travel take?这次旅行需要多长时间？Dad might know how to start that machine. 爸爸也许知道如何发动那台机器。2. may/might的用法(1)may也可表示邀请， 注意其否定回答为“No, 主语＋ mustn't/ can’t”。—May I go now? ——我现在可以走了吗？—No, you mustn't. ——不，你不能走。(2)may表示说话人的猜测， 认为某一事情可能发生，其否定结构为may not, 其过去式为might not。eg. The newspaper says that it might rain．(3)might表可能，其语气比may更委婉，更加不确定。His parents might come today. 他父母今天可能会来。一、单项选择1. Dirty air and water are harmful. They kill plants, and even people.
