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
