Unit 9Can you come to my party?第三课时(Grammar Focus3c)单元同步语法精讲精练在七年级下册第一单元我们已经学了情态动词can的相关用法，本单元主要学习情态动词can引导的一般疑问句及其回答。can引导的一般疑问句需将can放在主语之前。can表示“做某事的能力”，意为“能；会”，对以它开头的一般疑问句作肯定回答用“Yes，主语can.”，作否定回答用“No，主语cant.”。eg：Can you sing in English？你会用英语唱歌吗？Yes，I can./No，I cant.是的，我会。/不，我不会。can与第二人称连用，常用于熟人之间表示邀请或请求，即Can you.?接受请求或邀请时，常用Sure，Id love to./OK，that sounds great./Certainly./Of course等回答。拒绝邀请，一般不直接说No，而应说(Im)Sorry，I cant.以示礼貌，然后说明理由；也可用Id love/like to，but.委婉地说明不能接受的原因并表示歉意。【注意】发出邀请或请求时，也常用could使语气更委婉、客气。【拓展】can还可以表示推测，常用于否定句。eg：That man cant be Mr. Liu because he is in London now.那个男人不可能是刘先生，因为他现在在伦敦。 一、单项选择。1David，_ you please sweep the floor and take out the trash?OK，Mom.Acould BmayCshould Dmust2Its surprising that Mr. Mas little daughter _ speak English so well.Amust Bcan Cmustnt Dcant3_ you come to my party on Sunday?Sorry，Im not available.I _ study for the math test.(易错题)ACan；must BMust；canCNeed；may DMay；canABA4Look！Here comes your moms car.It _ be hers.She sold her car yesterday.Amust Bcant Cneednt Dmight5Can you come to my party on Wednesday?Sorry，I _I have a piano lesson.Acant Bcouldnt Cmustnt DneedntBA二、根据汉语意思完成下列句子。6这周末你能和我去看电影吗？好的，我很乐意。_ _ _ _ the movies with me this weekend?Sure，_ _ _7你能和我一起去购物吗？我恐怕不行。我感冒了。_ _ go shopping with me?_ _ _I have the flu.Can/Could you go toId love/like toCan/Could youIm afraid not本课时其他知识点精讲精练 invite动词，意为“邀请”，常用于以下结构中：invite sb. sw.邀请某人去某地invite sb. to do sth.邀请某人做某事accept动词，意为“接受”，强调主观上愿意接受，动作者本身是主动的。【拓展】receive动词，意为“收到”，强调客观收到，没有本身是否愿意接受的意思。eg：I received his gift，but I wouldnt like to accept it.我收到了他的礼物，但是我不想接受它。refuse动词，意为“拒绝”，与accept互为反义词。refuse to do sth.拒绝做某事refuse sb. sth.拒绝某人某物refuse sb./sth.拒绝某人/某物1Sometimes，I want to _ (拒绝) to do so much work，but usually I just _ (接受) it.2Kittys teacher Mrs.Xiao invited me _ (join) their school trip to the World Park.3I refuse _ (discuss) this question.refuseacceptto jointo discuss
