基数词变序数词的教学设计
教学目标:
让学生掌握如何将基数词变成序数词
教学重点及难点
让学生掌握如何将基数词变成序数词,理解并记忆口决。
教学过程: 一.片头:
内容:Hello,welcome to English world!本节微课重点讲解基数词变序数词
引出数词,数词分为基数词和序数词。基数词就是表示数目多少的数词,举例子。序数词就是表示顺序的数词,举例子。并说明本微课的主要教学内容:即,从几个方面来总结序数词的变化规律:一至十二几十几,和整十。
二:正文讲解
1.首先展示:
four----fourth
six----sixth
seven----seventh
启发引导学生发现这四个序数词的变化规律,就是在基数词后面直接加上th,也是大部分序数词的变化规律。
2.继续展示 : 1
one-----first
two-----second
three----third 引导学生观察后发现这三个序数词变化没有规律,所以要单独记忆。即:
一二三
单独记。3.继续观察:
eight----eighth
nine----ninth
用鼠标引导学生发现这两个序数词的变化:八要去掉基数词八中的字母t而九是去掉基数词中的e然后加上th的。
即:八去t,九去 e。4.引导学生再看一至十二中剩下的五和十二。
five----fifth
twelve—twelfth 对比后,引导学生指出序数词fifth和 twelfth是把基数词中的字母ve替换成f再加th的。即: ve要用 f 替。学习整十数词的变化规律。
twenty----twentieth
forty----fortieth
ninety----ninetieth 整十的序数词变化就是把基数词中的字母ty变成了tie再加上th的。即:ty变成tie。最后展示几十几的序数词变化形式:
twenty-one----twenty-first
thirty-six----thirty-sixth 97
ninety-seven----ninety-seventh 这三个序数词的变化规律是:若是遇到几十几,只变个位就可以。
三:总结巩固 基数词变序数词变化小规律总结成为口诀:
基变序 有规律,词尾加上th 一二三单独记,结尾带有tdd 八减t 九去e,ve要f替,th紧跟要牢记 若ty作词尾ty变成 tie,th千万别忘记 若是碰到几十几 ,只变个位就可以。四:练习
最后,做两个小练习,也能巩固学习一至十二的序数词的变化。
自我教学反思:本节微课任务明确,指向性强,学生的语法思维由抽象到形象,运用演绎归纳掌握了知识点,达成了知识目标。但是一节微课不可能学习所有和序数词有关的内容,很难做到面面俱到,所以我只是挑取了基数词是如何变化成为序数词的一小方面的问题,只是想在最短的时间里让学生掌握序数词的变化规律,这只是一个尝试,还有很多地方需要思考。由于长时间带班主任,我的声带有问题,自认为我录制时声音沙哑或许会给学生负面的学习动机。语言不够优美,没有抑扬顿挫,如果指出序数词前面经常和定冠词the连用的知识会更好。在今后的教学作中不求最好只求更好!
第二篇:英语基数词变序数词规律
英语基数词变序数词规律
英语中基数词变序数词一直是中考的重点,也是学生认为比较难掌握的知识点。在近几年的教学中,我不断摸索并借鉴其他教师总结了一首顺口溜帮助学生记忆基数词变序数词规律。实践证明,该方法是行之有效的,现整理出来和大家一起分享,如有不当之处,敬请批评指正。
基数词变成序数词,加上th 莫迟疑; 八去t,九去e, y结尾变ie;five,twelve 两兄弟,常用f替ve;若是遇到几十几,只变个位就可以; 只有三个特殊记,一二三尾t,d,d.释义:
基数词变成序数词,加上th 莫迟疑
基数词变序数词,一个大的原则就是在基数词词尾加上th,可以说绝大多数序数词都是以th 结尾的。如:six-sixth,ten-tenth.八去t,九去e, y结尾变ie;八(eight)变序数词第八时,需要把词尾字母 t去掉,然后再加th;九(nine)变序数词第九时,需要把词尾字母 e 去掉,然后再加th;英语中二十以上的整十都是以ty结尾的,对于这些基数词变序数词时需要把词尾的字母y 变成 ie,然后再加 th.如:twenty-twentieth.five,twelve 两兄弟,常用f替ve;five,twelve两个单词变序数词时,需要把词尾的字母 ve 换成f, 然后再加th.若是遇到几十几,只变个位就可以;
英语中表示几十几的基数词变序数词时,该单词的十位不用变,只需要把个位变成相应的序数词即可.如:twenty-four变成twenty-fourth.只有三个特殊记,一二三尾t,d,d.英语基数词变序数词中,只有三个需要特殊记忆,分别是第一(first),第二(second),第三(third).

基数词及序数词重要用法
1.基数词的用法
基数词用于表示事物的数量,在表示基数词时,要特别注意hundred, thousand, million, billion等几个词的用法:若其前用了基数词,则不论其面是否有of,都必须用单数形式(此时若带of则通常表示特定范围中的一部分);若泛指数百、数千、数百万等,则用 hundreds of, thousands of, millions of 等这样的结构。如:
Two hundred of the students are needed to plant trees this morning.今天中午需要200个学生去植树。
Hundreds of people attended the famous director’s farewell concert.好几百人出席了这位著名指挥家的告别音乐会。Thousands upon thousands of English words come from foreign tongues.成千上万英语单词来自外来语。2.基数词的复数用法
逢整“十”的基数词的复数形式可用于表示某人的大约年岁和世纪中的年代。如: The war broke out in the nineties.这次战争爆发于90年代。
Karl Mark began to learn the Russian language in his fiftieth.马克思五十多岁开始学俄语。3.序数词的用法
序数词用于表示事物的顺序,一般由与之相应的基数词加th构成(但有特殊形式需特别记忆);序数词主要用作定语,前面一般要加定冠词(或物主代词)。如:
Their second son is a doctor.他们的二儿子是个博士。
The hundredth cave that George has discovered in his lifetime is near the Alps.乔治一生中找到的
