Languagepoints1.Howmucharethesesocks?这双袜子多少钱？1)howmuch意为“多少”,常用于询问价格。如果询问的是可数名词单数或不可数名词的价格,后面的be动词形式用is；如果询问的是可数名词复数的价格,be动词形式用are。 如：Howmuchisthatpen?那枝钢笔多少钱？Howmuchisthebroccoli?花椰菜多少钱？Howmucharethesetomatoes?这些西红柿多少钱？ 【相关链接】howmuch也通常用来表示询问数量,后接不可数名词。如:Howmuchwateristhereinthebottle?瓶子里有多少水？Howmuchsaladisthereinthebowl?碗里有多少沙拉？ Howmuchmilkisthereintheglass?杯子里有多少牛奶？因为water和milk是不可数名词,所以动词be用单数形式is.如修饰可数名词问数量,则用Howmany.eg:Howmanyapplesarethereinthebag?袋子里有多少苹果？ 2)socks,shoes,shorts,trousers这类物品常常成对出现,所以它们做主语时,和它们搭配的谓语动词用复数形式。如：ArethosetrousersJim’s?那是吉姆的裤子吗？Theshortsare58dollars.这个短裤58美元。 【相关链接】如果这类词前面有“...pair(s)of(……条/双)”修饰,谓语动词就要根据pair的单复数形式发生相应的变化。如：Thepairoftrousersis98yuan.这条裤子98元。Twopairsofblueshoesare200dollars.两双蓝鞋200美元。 2.—CanIhelpyou?您想买什么吗？—Yes,please.Ineedasweaterforschool.是的。我想买一件毛衣。(P38)CanIhelpyou?是服务用语,在不同的场合意义不同。请看：1)—CanIhelpyou?您想吃点什么吗?(在餐馆)—Yes,please.Iwantahamburger.是的。我要个汉堡包。 2)—CanIhelpyou?想借什么书呢？(在图书馆)—Yes,please.IneedanEnglishdictionary.是的,我想借一本英语词典。3)—CanIhelpyou?您想买什么吗?(在商场)—Yes.Iwanttobuyabag.是的,我想买个包。 【相关链接】句子WhatcanIdoforyou?和CanIhelpyou?同义,有时可以互换。No,thanks,Justhavealook.ANSWERS:Yes,please.Ineed/want… Ⅰ.按要求写出各词的适当形式。1.short(反义词)2.black(反义词)3.this(复数)4.shoe(复数)5.small(反义词)longwhitetheseshoesbigExercises 6.dollars(单数)7.have(第三人称单数)8.those(单数)9.doesnot(缩写)10.isn’t(复数)dollarhasthatdoesn’taren’t 1.--WhatcanIdoforyou?--______________.A.Yes,youcangiveaskirttomeB.IwantaskirtC.No,IcandoitmyselfD.IcandowhatIwant2.--Howmuch______theskirt?--______thirtyYuan．A.is;It'sB.are;They'reC.is;They'reD.are;It'sⅡ.单项选择。BA 3.Theyellowshorts______15yuan.A.isonsaleB.areonsaleC.areonsellforD.areonsalefor4.Thishatis_____.A.10yuan'sB.10dollarC.10dollarsD.dollar10解析:onsale意为“有售，上市，廉价出售”。dollar是美国、加拿大、墨西哥和某些国家的货币单位,相当于我国汉语当中货币单位Yuan,但是我们汉语中货币单位没有复数形式。CD ()5.Ithinkyourtrousers_____verynice．A.beB.isC.amD.are解析:在英语中,袜子、裤子都用复数形式来表示,答案为D。若要表示一双袜子、一条裤子可以用词组apairof。如：apairofsocks一双袜子，apairoftrousers一条裤子。D Ⅲ.根据提示完成句子。1.--Thankyou．--You'rewelcome.(改为同义句)--Thankyou．--That's_________．2.Theredsweaterisonly30dollars.(对划线部分提问)___________istheredsweater?allrightHowmuch 3.Iwantapairofshoes.(划线提问)________youwant?4.Helikesyellow.(划线提问)_______________helike?5.Thoseblackbagsare30yuan.(划线提问)_______________thoseblackbags?6.Icanhelpyou.(一般疑问句)____youhelp_____?WhatdoWhatcolordoesHowmuchareCanme A:1._____________CKclothesstore.CanIhelpyou?B:Yes,please.Iwantashirtformyson.A:2._______________________?B:Blue.A:3.______________________?B:Letmehavealook.4.______________.Doyouhaveasmallone?WhatcolordoeshelikeWhataboutthisoneOh!It’stoobigWelcometoⅣ.完成对话 A:Yes.______________________.B:Howmuchisit?A:It’s60yuan.B:Oh,no,it’stoodear.Canitbealittlecheaper？A:OK,Comeon,Whatabout55yuan?B:OK.______________________.Thanks.A:______________________________.I’lltakeitHereyouareYou’rewelcome 1.Reviewthenewwords;socksT-shirtshortssweaterbaghattrousersshoes2.Recite(背诵)thesentencesinGrammarFocus.3.Practicethecolorsandprice.Homework ThankYou!
