第一课时SectionA(1a~1c)1.情态动词can的用法小结:(1)表示能力,意为“能,会”,其过去式为could。(2)表示“请求许可”。在这一用法中,can与could都表示现在,但could比can语气更加委婉。一般用在疑问句中,句型为Canyou…?肯定回答为:Yes/Sure/Certainly,I'dloveto。否定回答常为:I'msorry/Sorry,Ican't。(3)表示可能性,常用于否定句中。eg:Thiscan'tbetrue.这不可能是真的。2.【辨析】haveto与musthaveto表示客观需要,有人称、数和时态的变化;其否定形式为don'thaveto“不必”。must表示说话人的主观看法,认为有必要或义务去做某事,没有时态和人称的变化;其否定形式为mustn't“禁止”。3.onSaturdayafternoon意为“在星期六的下午”。泛指在一天的早上、中午或下午用in,而在具体的某一天的早上、中午或下午用on。4.prepare动词,意为“使做好准备;把……准备好。”常用搭配:prepareforsth.为某事做准备5.havetheflu患流行感冒6.gotothedoctor看病一、根据句意及汉语提示写单词完成句子。1.Manystudentsarebusy______________(做准备)fortheEnglishparty.2.Wehavealotof________(考试)everyyear.3.Ididn'tgotoschoolbecauseIhadthe________(流感).4.YesterdayKangkang________(遇见)hisfriendMei.5.Idon'tfeelwelltodayandIhavetogotothe________(医生).preparingexamsflumetdoctor二、单项选择。6.—Canyoucometomyparty?—________.A.Sure,I'dlovetoB.Ican'tgothereC.No,Iwon'tgoD.Yes,Iwill7.—Canyouhelpmewithmymath?—________,Ican't.I'mtoobusy.A.CertainlyB.NotC.SorryD.Sure8.Bobcan'tcomeouttoplaybecausehe________helpDadinthegarden.A.canB.can'tC.hastoD.mustACC9.—________youshowmeyournewcoat?—Sure.Hereyouare.A.MayB.MustC.CanD.Are10.Heoftenplaysbasketball________theafternoon,butheruns________Mondayafternoon.A.on,onB.in,inC.on,inD.in,onCD三、按要求完成句子。11.Ihavetohelpmyparents.(改为否定句)I_____________________helpmyparents.12.Iampreparingformy_English_exam.(对画线部分提问)________you___________________?13.Hemeetshisfriendson_Sunday_morning.(对画线部分提问)________________he________hisfriends?14.Canyoucometomyparty?(用havetheflu作答)_______________________________________________________________...
