6、xty六十seventy七十eighty八十ninety九十这类基数词共有八个。都是十位的整数,均以后缀-ty结尾。其中sixty、seventy、eighty、ninety基本上是在相应的基数词后面加上后缀-ty。但要注意eighty的拼法,eight本身有t字母,因此只加-y。拓展4、第四类:这一类和很简单,可以看成是一种合成词。其结构方式是:用十位整数加上个位整数,其间用连字符号“-”连接,表示“几十几”。这类基数词的变化都是规则的。如:twenty-one二十一forty-six四十六seventy-eight七十八ninety-five九十五拓展Listenagain.Circlet

15、rts,too?You:Yes,ourshortsareonly16dollars.Boy:OK.Illtaketheshoesandtheshorts.1.基数词的表达1)one到twelve,拼写和读音无规律可言,只能逐一记忆。2)thirteen到nineteen,表示“十几”,在个位数后加后缀-teen,其中要注意thirteen,fifteen和eighteen的拼写。3)twenty到ninety,表示“几十”,以ty结尾,但需注意twenty,thirty,forty,fifty,eighty的拼写。4)2129直到9199,表示“几十几”,用整十位数加个位表示,中间用连字符“-
16、”把十位和个位连接起来。5)onehundred意为“一百”,也可说ahundred,hundred可加具体数字,如ninehundred(900)。2.基数词的用法:基数词只能修饰可数名词,要注意数词和名词在数上要保持一致。如:onestudent一名学生twoboys两名男孩twentyapples二十个苹果thirty-threeeggs三十三个鸡蛋3.Comeandbuyyourclothesatourgreatsale!buy用作动词,意为“买”,常用短语为:buysb.sth./buysth.forsb.意为“给某人买某物”。e.g.Letsbuymomanewsweater.(=
17、Letsbuyanewsweaterformom.)我们给妈妈买件新毛衣吧。clothes指身上穿的各种服装,包括上衣,内衣,裤子等,是衣服的总称。它不能直接与数词连用,但可以与some,many,these或those等连用。e.g.Look!Someclothesareonsaleoverthere.看!那边的衣服大减价了。sale是动词sell的名词形式,常用短语:onsale,意为“出售;廉价出售”,其同义短语为atagreatsale。e.g.Thesweatersinthestoreareonsaletoday.今天这家商店的毛衣大减价了。4.all与定冠词、指示代词、形容词性物主
18、代词等限定词连用时,all应放于这些词之前。如:allthestudents所有这些学生allherclothes她所有的衣服allthoserooms所有那些房间5.Wesellallourclothesatverygoodprices.atverygoodprices意为“以合理的价格(出售)”。price用作名词,意为“价格”。e.g.Whatsthepriceofthebook?这本书多少钱?Theyhavesweatersinallcolors,atthepriceof15each.他们有各种颜色的毛衣,每件售价是15美元。6.Forgirls,wehaveskirtsinpurpl
19、eforonly20.1)forgirls中的for是“对于而言”;foronly20中的for是“交换”的意思。2)该句中的in后接颜色的词,表示“穿颜色的”。e.g.Thegirlinredismysister.那个穿红衣服的女孩是我妹妹。一、填表格,记数字。101115tenthirteentwelve201830sixteennineteen262839twenty-onethirty-fiveeleven13fifteen12twenty16eighteen19thirtytwenty-six21twenty-eight35thirty-nineExercises二、做数学题,学英语
