一、填表格,记数字。
twenty-eight
thirty-nine
(1)ne—twelve, 无规律可言,应逐一记忆。(2)13~19的基数词都以—teen结尾。记住三个特殊写法的。 thirteen furteen fifteen sixteen seventeen eighteen nineteen(3)20~90中整几十的基数词都以-ty结尾。 twenty thirty frty fifty sixty seventy eighty ninety(4)“几十几”的表达式:整几十+连字符-+个位数 frty-ne 41 fifty-tw 52 sixty-three 63
数词分为 ,表示数量多少的数词叫做基数词,如ne, tw, three等。
英语数词不难记,找出规则就容易。 零至十二形各异,一个一个单独记。 后面加teen变十几,thirteen, fifteen看仔细。 eighteen只有一个t,两个音节念清晰。 表示“几十”要加-ty, twenty, thirty 是特例。表示数字“几十几”,连字符号别忘记。
(5)一百的表示方法为ne hundred或a hundred。 要表示“几百”,用具体数字加上hundred, 如five hundred(500),注意此时的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:ne hundred and tw(102)。
hundred, thusand(千)等的复数形式可表示不确定的数目。在这种情况下它们须用复数形式,且后面要加f。eg:hundreds f teachers 数百位老师 thusands f students数千位学生
We plant ________trees every year.(四川雅安)A.hundreds f B.hundred f C.five hundreds D.five hundred f
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。eg:ne banana 一根香蕉 five bys 五个男孩
Lk at the pictures t ask and answer in pairs:
A: Hw many …d yu need?B: I need …A: Hw much… d yu need?B: …
可数名词是指能以数目来计算,可以分成个体的人或东西;不可数名词是指不能以数目来计算,不可以分成个体的概念。
可数名词(Cuntable Nuns)
不可数名词(Uncuntable Nuns)
I wuld like an egg and sme fish.Wuld yu like sme eggs, Maria?I 'd like sme chicken.
可数名词和不可数名词:
可数名词有复数形式,当它的复数形式在句子中作主语时,句子的谓语也应用复数形式。可数名词前可用具体的数词来表示具体的数量。e.g. ne egg a pen tw eggs tw pens不可数名词一般没有复数形式,只有单数形式,它的前面不能用不定冠词a / an ,若要表示它的个体意义时,一般要与一个名词短语连用,相当于中文里的【数词+( 量词)+ 名词】,其中的量词意义依与具体的名词搭配而定。e.g. a pair f shes a cup f cffee a bttle f water
询问可数名词数量时,用Hw many + 可数名词复数形式。 如:Hw many apples d yu have? 你有多少个苹果? Hw many hamburgers d yu want? 你想要多少个汉堡?可数名词确定数量的表达:1. 数目+可数名词 如: an/ ne apple tw apples2. 数词+表示量的名词+f 如: a bx f apples tw bxes f apples. a kil f apples 3 kils f apples
用第2种 +f结构表示时:可数名词始终用复数形式,数词是单数时,表示量的名词用单数。数词是复数时,表示量的名词用复数。
Hw much 除了询问物品价格之外,还可以询问不可数名词数量,用Hw much + 不可数名词如:Hw much water wuld like? 你要多少水? Hw much rice d yu have fr dinner? 你晚餐吃了多少米饭?不可数名词确定数量的表达:数词+表示量的名词+f 如: a glass f milk tw glasses f milk. a kil f milk 3 kils f milk
不可数名词不能直接用数词来表示具体数量,只能用+f结构:数词是单数时,表示量的名词用单数。数词是复数时,表示量的名词用复数。不可数名词没有复数形式。
可数名词不确定数量表达法:用sme/any/many/a lt f / lts f/ hundreds f / few/ a few等放在可数名词 如: sme apples, many pictures, hundreds f teachers不可数名词不确定数量表达法:用sme/any/much/a lt f / lts f/ little/ a little 等放在不可数名词 如:sme water, much milk, lts f rice
名词不确定数量的表达法:
既可修饰可数名词也可修饰不可数名词的词有: sme/ any (一些), a lt f/ lts f (许多)
1.都可以加可数名词复数或不可数名词。eg. sme hamburgers sme milk2.sme多用于肯定句或希望得到对方肯定回答的一般疑问句中。eg. I need sme apples. Wuld yu like sme bread?3.Any多用于否定句或一般疑问句中。eg. I dn’t have any milk. D yu have any bananas?肯定句中的sme在改为否定句和一般疑问句时需要改成any,但希望得到对方肯定回答的一般疑问句除外。
