Unit7GrammarandWriting目标导航目标导航Grammar基数词Writing谈论物品的价格及写广告知识精讲知识精讲单元语法专讲：一、howmuch引导的疑问句知识点01howmuch询问价格用法howmuch常用于询问某物的价格，其结构为“Howmuch+be动词＋主语？”。当主语是可数名词单数或不可数名词时，be动词用is,答语为：“It's...”；当主语是可数名词复数或不仅仅是一种东西时，be动词用are,答语为：“They're...”上述两种情况都可直接回答钱数。－Howmuchisthesalad?沙拉多少钱？－It'sfiveyuan./Fiveyuan.五元。－Howmucharetheapples?这些苹果多少钱？－They'reeightyuan./Eightyuan.八元。【即学即练1】－istheschoolbag?－60yuan.A.HowoftenB.HowoldC.Howmuch解析：由答语可知是询问书包的价格，应用howmuch提问。知识点02询问价钱的同义句用法询问商品价格时，还可以用“What'sthepriceof..?”句型，意为“。·····的价格是多少？”；无论被询问的物品是不可数名词还是可数名词的单数或复数，be动词都用is,不能用are.其答语为：“It's...（价格是）······”这是由price决定的，用心哦！－What'sthepriceofthebook?这本书的价格是多少？－It'sfiveyuan.5元。－What'sthepriceoftheseeggs?这些鸡蛋多少钱？－It'stenyuan.10元。知识点03【高频】辨析howmuch与howmanyhowmuch后接不可数名词,对不可数名词数量提问。单独使用，后不接名词提问物品价格。howmany后接可数名词复数,对可数名词数量提问。Howmuchmeatdoyouwant?你想要多少肉？－Howmucharethepencils?这些铅笔多少钱？－Theyarefortyyuan.它们40元。Howmanypearsdoyouwant?你想要多少梨？－Howmanypeoplearethereinyourfamily?你家有几口人？－Therearefive(people).有五口人。Howmuch用法1.“多少”，用来询问事物的数量，后接不可数名词。Howmuchbreadisthereonthetable?桌子上有多少面包？2.“多少钱”，可单独使用，用来询问某物的价格。Howmuchisyournewputer?你的新电脑多少钱？【即学即练2】－DisneylandparksarethereinChina?－Two.A.HowmanyB.HowoftenC.HowsoonD.Howlong解析：根据答语“Two.”可知是询问可数名词的数量，应当用howmany提问。单元语法专讲：二、基数词知识点04定义表示事物数量多少的数词叫作基数词，如one,two,three等。知识点05基数词的拼写（1)onetwelve,无规律可言，应当逐一记忆。（2)thirteennineteen,表示“十几”，在个位数后加后缀－teen,读作／ti:n/,但要注意下面几个词的拼写：thirteen(13),fifteen(15),eighteen(18).（3)twenty到ninety,表示“几十”，以－ty结尾，但需注意下面几个词的拼写：twenty(20),thirty(30),forty(40),fifty(50),eighty(80).（4)“几十几”的表达方法：用整十数加个位数表示，中间用连字符“－”把整十数和个位数连接起来。如：twentyfive(25),sixtyeight(68).（5）一百的表达方式为onehundred或ahundred.要表示“几百”，用具体数字加上hundred,如fivehundred(500),意此时的hundred是单数形式。表示“几百几”时，要在百位数和十位数（或个位数）之间加and.如：onehundredandtwo(102).数词记忆规则歌诀：基数词词不难记，找出规律很容易：一至十二形各异，加上－teen为十几，thirteen.fifteen看仔细eighteen只有一个t;twenty却是很奇怪，forty本身也不乖，eighty一起搞例外，跟着也把规则坏；十位后面是个位，表示数字“几十几”，表示“几百几十几”，and常把百、十系。勤学妙记加练习，hundred就是你的好成绩。知识点06基数词的用法1.用法表示数量，置于名词之前。Shehastwobrothers.她有两个弟弟。表示编号，置于名词之后。TheyareinClassFive.他们在五班。表示号码。Hisphonenumberis3375683.他的号码是3375683.表示时间。It's10:00now.现在是10点。表示年龄。Mysisteris8yearsold.我妹妹8岁了。用于计算。Twoandfourissix.2加4等于6.2.基数词只能修饰可数名词，要注意基数词和名词在数上要保持一致。onebanana一根香蕉fiveboys五个男孩3【难点】hundred,thousand,million等与具体数字连用时，用单数形式，且后不接介词of;当其前面没有具体数字时，要用复数形式，且后面要加of.－s和字母f相伴出没！threehundredteachers三百位老师hundredsofstudents数百名学生【即学即练3】TodayisJack'sbirthday.Heisyearsoldnow.A.fourteenthB.fourteenC.thefourteenthD.thefourteen解析：句意为“今天是杰克的生日。他现在14岁了”。表示年龄用基数词，而且前面不加定冠词。【即学即练4】Wherewereyouborn,Michael?－Iwasborninasmallvillagewithonlythreepeople.A.hundredB.hundredsC.hundredsof答案A【即学即练5】Therearestudentsinourschool.A.hundredsB.hundredsofC.hundredof解析：hundred前面没有具体数字时，要用复数形式，且后面要加of.答案B能力拓展能力拓展考法01单元话题书面表达：谈论物品的价格及写广告【典例1】单元话题毛毛服装店开张了，请你根据提示写一篇60词左右的广告。要求：①广告简单易懂，同时突出商品的亮点。②灵活运用所学过的单词、短语及句子。③写清所售商品及其价格。审题指导（把握中心，得方向分）1.要使用祈使句，如：eandbuy...2.注意价格表达中介词at和for的正确运用。如：Wehave..atverygoodprices./Wehave..onlyfor../Wesell..onlyfor...写作方法（学会方法，巧得高分）“首尾呼应法”写广告词一、开头：点出店名二、正文：商品及其价格三、结尾：宣传号召写作模板（学会套路，得出彩分）开头点出店名eto...now!/etobuy...now!正文商品及其价格Wehave+商品名（hats,bags,skirts...)+for+价格。。。结尾宣传号召eto...now!/etobuy...now!经典词句（妙用句式，得出彩分）单词store,hat,bag,socks,Tshirt,shorts,shoes,trousers,skirt,sweater,price,color短语ataverygoodprice,bagsforsports,eandsee,havealookat...,differentcolors,apairof句子eandbuy...at...Store!/Wehave...for.../Forboys,youcanbuy.../Forgirls,wehave...范文赏析（书写工整，得印象分）Maomao'sClothesStoreeandbuyyourclothesatMaomao'sClothesStore!Doyoulikehats?Wehaveblackandbluehatsfor¥12.Wehavesweatersataverygoodpriceonly¥60!Doyouneedbagsforsports?Wehavegreatbagsforonly¥45.Forboys,youcanbuysocksforonly¥8.Forgirls,wehaveskirtsforonly¥18!etoMaomao'sClothesStorenow!名师点评本文运用了“首尾呼应法”写广告词。第一：篇首用号召性句型点明了服装店名称；第二：接下来介绍店里所售商品及其价格；用疑问句引出所售商品（第二段），亲切而自然，句式灵活；句子运用准确，如Wehave..for../Forboys...Forgirls,..;短语运用恰当，如ataverygoodprice,bagsforsports等，让人印象深刻，语言丰富多彩，行文流畅自然。第三：尾句又发出号召，与首句呼应，再次点题。分层提分分层提分题组A基础过关练一、单项选择1．_________doesthecatweigh?A．Howmany B．Howmuch C．Howheavy D．What2．—________isyourphonenumber?
