1、数词 教学内容 你知道下面的数字分别是阿拉伯数字中的几吗? I, II, XII, V, VI, VII, IX, III, IV, X, VIII, XI 你知道1-10在中文中对应的繁体字怎么写吗? 批注:芝麻开门部分可以先从学生不太熟悉的罗马数字开始,教案中给出的数字已经打乱顺序,防止学生按照顺序往下数,下面给出了中文的一到十,询问孩子学习了这么长时间的语文后是否会写中文的数字,然后导出本节课的主题:数词。 初一英语数词详解 一、基本分类 1)基数词 表示数目多少的数词叫基数词,如 one, five, ten,
2、thirty, sixty-five 等。 2)序数词 表示顺序先后的数词叫序数词,如 first, sixth, tenth, twenty-first 等。 三、用法详解 1、基数词的构成 1) 1-20表达英语中有相对应的单词,两位数的表达方法为整数加个位数组成,如twenty-one;三位数如one hundred and twenty-one, 百位和十位之间加and,后面两位数要加连字符,四位以上只有在百位和十位之间加and,如1134 one thousand, one hundred and thirty-four。 英语中没有万,千万,亿
3、等单位,如果需要表示万的话用thousand计算,例如1,4283 fourteen thousand two hundred and eighty-three;如果需要表示千万和亿的话用million计算,如2,1824,5200 two hundred and eighteen million two hundred and forty-five thousand and two hundred。 2)用作基数词单位的 hundred, thousand, million, billion 不带复数词尾-s,但若用于表示数百、数千、数百万这样的泛指,则用复数。如: A
4、bout two thousand people died in the earthquake. 大约有两千人在地震中丧生。 Thousands of people go to the seaside every year. 每年成千上万的人到海滨去。 典型例题 ( ) Two _________(hundred) of students took part in the sports meeting last week. 解析:正确答案为hundred. 前面出现具体数字,后面只能用hundred,但是后面出现了of, 很多学生会误写成hundreds,
5、 但是这边的of 表示的范围,这句话的意思是:上周学生中的两百个人参加了运动会。 3)表示整十的基数词用复数形式可以表示人的大约岁数或年代。如: He is in his early twenties. 他才二十出头。 This took place in the 1930s. 这事发生在20世纪30年代。 数词和名词,形容词连用时有连字符和没有连字符在句中的位置是有区别的,例如five-year-old和five years old. 有连字符的在句中做定语,修饰后面的名词;无连字符的在句中做表语,放在系动词后面。 The five-year-old boy can
6、 dress himself.那个5岁的孩子自己能穿衣服了。 My son is a five-year-old boy.我的儿子是一个五岁的男孩。 2、序数词的构成 1)许多序数词是由相应的基数词后加词尾-th构成的,如four / fourth,sixteen / sixteenth; twentieth, thirtieth, fortieth 等表示整十的序数词,由相应的基数词将词尾y改为ie,再加-th 构成。 几个常考的不规则变化序数词需注意:ninth,twelfth,fortieth,ninetieth等。 2)非整十的多位数,将个位数
7、变成序数词即可:twenty-first(第21),thirty-sixth(第36),ninety-ninth(第99),three hundred and sixty-fifth(第365)等。 3)序数词前通常要用定冠词,但当序数词前有形容词性物主代词时,通常省略其前的定冠词。如: Today is my father’s fortieth birthday. 有时序数词前不用定冠词,而用不定冠词,表示次第在原有基础上的增加。如: We’ll have to do it a second time. 我们得再做一次。 3、数词的用法 1) 时刻的表示
8、小时,分钟,秒钟都用基数词表示,例如:five o'clock, seven thirty, two to eight等。 2)年,月,日的表示:年份用基数词,日用序数词。例如:in 1999,五月八号 写作 May the eighth 表示在几世纪这个概念时,用序数词。例如:在21世纪 写作 in the twenty-first century. 3)在分数的表达,分子须用基数词,分母用序数词。分子如是1以上的基数词,分母须用复数形式。 如1/3写作a/one third,3/4写作three fourths。 4)编号的表示:基数词放到名词的后面,前面的名词要
9、大写;序数词放在名词的前面,要加定冠词。例如:Lesson 1,the first lesson. 批注:本部分可以依照从基数词到序数词的顺序,给孩子讲解数字的表达方法,基数词变序数词的方法和特殊的书写,数词部分一些知识点比较零散,老师在讲完知识点后要注意以简洁的语言给孩子系统总结。 (建议5-10分钟) I. 数词填空 1. Even a child knows September is the ______ month of a year.(nine) 2. Three ______________ (hundred)of the students are dancing

ABCAD ABAAA BA score:____________ 批注:这个部分还是以学生练习为主,学生在做完之后,老师进行批改,然后如果学生错误较多的话老师还是需要在讲解过程中回顾知识点,如果学生错误很少,老师可以挑几道题让孩子自己讲解,看看孩子是不是真正掌握了。 (建议2-5分钟) 放电影回顾式学习法 批注:第一步采用放电影学习法,让学生自己回忆在本模块学到了哪些知识点;老师注意引导孩子对该部分语法知识形成系统认知。第二步是错题再次回顾总结,在“斩妖除魔”环节,学生做了几道题目,需要再次让学生总结出现错误的原因及下次如何避免.
