第一篇:序数词教案
成人高考英语
第七章 数词的基本用法:序数词 教学设计
安远中等职业学校 杜譞
教学内容:序数词
教学目标:能听、说、认读序数词。
教学重点:掌握序数词的构成及其基本用法。
教学难点:基数词转化为序数词,分数的构成,日期的表达。
教学方法:对比法、归纳演绎、TPR
教学准备:图片、单词卡、课件
教学过程:
Step 1.Preparation 1.Greetings: Say hello.2.Sing a song.3.Review the numbers。让学生把课件上的单词用英语读出来。(这个环节既复习了上一课内容基数词,又为序数词的新授做铺垫。)
4.Ask and answer“How old „„? I’m „„”“How many „„? ”“How much „„”(学生根据实际情况回答)(目的复习基数词在实际情境中的运用的。)最后教师拿出图问: Where is the living room? It’s on the first floor.Step 2.Presentation
1.单词导呈
(1)教学单词 first.利用图片直接介绍This is a living room.It’s on the first floor.老师指着图片介绍,学生跟读单词,老师同时板书单词。
(2)运用“Where is the living room? 引出It’s on the first/second floor.”利用相同方法教授单词second和third。(在学习这几个单词时,可以采用TPR的方法,增加趣味)
(3)出示序数词概念:表示数目顺序的词,我们称为序数词。(明确序数词概念)
(4)运用单词图片简单复习刚学的新词。
(5)课件出示基数词,并逐个出示20以内的序数词(通过游戏PK的方式巩固序数词单词)
(6)教授整十和几十几的序数词。(老师要让学生明白序数词和基数词的不同,并通过观察归纳出基数词变序数词的方法。)2.归纳出基数词变序数词的口诀。
基变序,有规律。
1,2,3,特殊记,词尾字母t,d,d;(first,second,third)8减t,9去e,f来把ve替;
(eighth,ninth)
(fifth,twelfth)单词ty作结尾,ty变成tie;(twentieth)
若是碰到几十几,只变个位就可以。(thirty-first,sixty-fourth)(口诀有助于学生对序数词构成方法的记忆)
合作学习。
The students read the words in groups.3.序数词的简写形式:是由阿拉伯数字之后加上单词最后两个字母组成,读音不变。
4.序数词的基本用法:
(1).用来表示事物的顺序:the second lesson
(2).表示年代世纪:the seventies of the 20th century或 the seventies of the twentieth century
(3).表示日期:1949年10月1日:October the first,nineteen forty-nnine(注意日期的缩写表达及读音)
(4).分数的表示:分子用基数词,分母用序数词,分子大于1时,分母用序数词复数。
one-fifth Step 3.Practice
课件出示题目,学生完成相应练习。(通过答题,进一步巩固序数词的在实际中的基本用法。)
Step 4.Prolongation
1.再次通过星期问答“What day is it? It’s Thursday.”导出星期四是感恩节,教育学生要心怀感恩之心。
Step 5.Homework
1.熟读序数词单词。
2.掌握序数词的变化规律。
3.抄写序数词,p67表格里的所有序数词,每个单词抄一次。
4.复习序数词的基本用法
第二篇:初一英语数词、序数词教案
(一)基数词 在英语中表示数目的词称为基数词。1.基数词的构成(1)1-20 one,two,three,four,five,six,seven,eight,nine,ten,eleven,twelve,thirteen,fourteen,fifteen, sixteen,seventeen,eighteen,nineteen,twenty(2)21-99 先说“几十”,再说“几”,中间加连字符。
23→twenty-three,34→thirty-four,45→forty—five,56→fifty-six,67→sixty-seven,78→seventy-eight,89→eighty-nine,91→ninety-one(3)101—999先说“几百”,再加and,再加末两位数或末位数; 586→five hundred and eighty-six,803→eight hundred and three
(4)l,000以上,先从右往左数,每三位数加一个“,”,第一个“,”前为thousand.第二个“,”前为 million,第三个“,”前为billion(美式)或thousand ,million(英式),然后一节一节地表示。1,001→one thousand and one
9,785→nine thousand, seven hundred and eighty-five 18,423→eighteen thousand,four hundred and twenty-three 6,260,309→six million two hundred and sixty thousand three hundred and nine
750,000,000,000→seven hundred and fifty, billion(美式)seven hundred and fifty thousand million(英式)
4.基数词的用法:
1.表年代。年份通常分成两部分说。例如:
1626 年sixteen twenty-six
2000 年twenty hundred/two thousand 1902年 nineteen o(或者and)two/nineteen hundred and two
2003→two thousand and three 2.表时间
①整点5:00 five/five o'clock ②半小时以内(包括半小时)
eleven thirty(钟点+分钟)
half past eleven(分钟+past+钟点)
eight twenty
twenty past eight ③超过半小时(到下一个钟点)
one fifty-eight(钟点+分钟)
two to two(分钟+to+下一个钟点)
注意:半小时以内的表达用介词past,表达“几点过几分”之意;超过半小时要用介词 to,表示“到下一个钟点还有几分”(即“几点差几分”)之意。
④一刻(15分钟)常用a quarter表示。如:a quarter to seven六点四十五分(七点差一刻)
a.m.表上午,p.m.表下午。例如:7:20a.m.早7点20分。
3.表电话、车牌等号码
碰到号码应把数字分开一个个说。“o”读成[u],英国人常把相同的两个数如22,读作 double two。例如:045-4166386o four five-four one double six three eight six
4.表长、宽、高、深,货币等计量
①货币的读写。
7.35seven dollars thirty-five cents七美元三十五美分
£3.75three pounds seventy-five pence三英镑七十五便士
¥5.24 five yuan twenty-four fen五元二角四分
a five-pound note一张五英镑的钞票
注意:dollar,pound,cent有复数变化,而人民币的yuan,fen无此变化。
②年龄、长、宽等计量的表达法。
He is sixteen(years old),and he's one and a half metres tall.
5.表编号,即在特定的一些用法中表顺序。
Lesson 9=Lesson Nine =The Ninth Lesson第九课(注意大小写变化)
Page 51=Page Fifty-one第五十一页
Room 203=Room two o three 203房间
the No.17 bus =the number seventeen bus第十七路公共汽车
6.数的计算(初中仅见加法表达)
“How much/What is two and four?”“Two and four is six.” 7.温度及比赛分数的读写
①温度The temperature will be 2—9.(2—9读写作two to nine)
②比赛分数
At the end of the first half we were winning 2:1.(2:1读写作two to one)
8.数字的具体表达与约略表达
①具体表达ten
(十)→ten books(十本书)→ten of the books(其中的十本书)
②约略表达tens(若干个“十”)→tens of the books(数十本书)。依此类推:
hundreds(若干个“百”)→hundreds of...(数以百计的……,成百上千的……)
thousands(若干个“千”)→thousands of...(数以千计的……,成千上万的……)。例如:
There are over seven hundred students on the ground.操场上有七百多名学生。
There are(several)hundreds of students on the ground.操场上有几百名学生。
应注意hundreds of...等前可用some,several,many,tens of...等词语修饰。
9.基数词的其它表达
①表“一次、两次”英语用once和twice。“三次”用three times,依此类推。
②注意下列表达
in one's teens在十几岁时;in one's twenties在二十多岁时;in the nineties在九十年代;one or two hours一两个小时;two hours and a half =two and a half hours两个半小时
10.小数的表示方法:
小数的表示法和汉语中小数表示法一样,小数点后的数字是“ 见几读几”,点用point 表示。
27.832 twenty-seven point eight three two 3)百分数 40%----forty percent 0.3%----(zero)point three percent 11.表示年代或岁数时,用逢十的基数词的复数形式 in the 1960s 二十世纪六十年代 in his fifties 在他五十多岁的时候
in his early twenties 在他二十岁出头的时候 表示十几岁时要用in one’s teens
