自然拼读全ppt课件

自然拼读课程,Phonics,1,Phonics自然发音法是一套用自然记忆 的方式，建立字母与发音的直觉音感。不 用借助音标，看着字母就可以直接读出该 词的发音，解决单词不会读，无法拼的问 题。 简单说：“自然拼读法”是教学生如何看词读音或是听音拼词的方法。,2,为什么要学习自然拼读法？,美国斯坦佛大学曾经以计算机分析字母与音位的对应关系，结果发现17,008个常用词中 84%的字母与其读音是完全对应的 13%的字母与其读音是不完全对应的 3%的字母与其读音的对应关系完全无法预测,3,自然拼读法可以帮助学生,见词能读 听词能写 不容易遗忘 提高阅读和写作能力,4,一、 同形不同音的字母及音标,b,/b/,book big bag box,/d/,d,desk doll dog dad,f,/f/,fine friend fly foot fan,h,/h/,hat he house hand,j,/ d /,jeep jam jacket jar,k,/k/,kite cake black thank,5,l,/l/,leg left ruler flag lamp,/l/,apple bowl tell old,m,/m/,am map my mouth,n,/n/,no know new hand,p,/ p /,map jeep pig pea,qu,/kw/,quite quilt quick,同形不同音的字母及音标,6,r,/r/,red radio brother racket,/t/,t,it sit not that table little,v,/v/,five vase very seven,w,/w/,we window watch want,x,/ ks /,box six fox,z,/z/,zip zoo,同形不同音的字母及音标,7,Vowel,8,二、开音节与闭音节,1）音节按读音可以分为开音节和闭音节,开音节又可以分为绝对开音节和相对开音节,A. 绝对开音节：是指一个元音音素后面没有辅音音素 而构成的音节,例如：we, hi, yo-yo, hi, no, be 等,B. 相对开音节：是指一个元音音素后面有一个辅音音素(除r)之外，最后是一个不发音的e字母构成的音节，,例如:take, make,9,闭音节：指元音字母后面有辅音字母(辅音字母r除外)构成的音节,闭音节,元音字母 a, e, i(y), o, u 在重读闭音节中分别读 / /e/ /i/ / /,如 hand, help,lip,gym,hot,club.,10,II.
