初一英语音标教学案.

1、龙冈初中初一英语音标教学案英语共有 48 个音素，其中元音音素20 个，辅音音素 28 个。英语辅音和元音在语言中的作用相当于汉语中的生母和韵母。记录英语音素的符号叫做音标。音标放在两条斜线（/），以免和字母混淆。第一课时教学目标： 1.学会 20 个元音音素的读和写2.了解什么叫重读开音节。3.学习五个元音字母在重读开音节中的读音。4.熟练掌握重读开音节的拼读规则。学习过程：1.学习单元音/i:/,/I/,/e/,/?/?:/,/?/,/?/u:/,/? /,/?:/,/? /,/:/教法： a.教师朗读并板书b.教师领学生齐读c.学生个别读写 .2.学习双元音/ai ei i? ?u u?

2、 au ? ? i3.根据读音写音素： _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _.4.单词按音节来划分,分为单音节词,双音节词和多音节词.单音节词中,常常分为重读开音节和重读闭音节.重读开音节： 1.结尾的三个字母 ,是一个元音字母 +一个辅音字母 +一个不发音的 e构成 .2.直接以元音字母结尾5.认识重读开音节： 1） cake face game joke2) these he we me3) bike fine kite nice4) home nose no go 5) cute use music pupil(让学生齐读这些单词，体会其中元音字母的读音，并总结

3、重读开音节的构成）6 根据读音规则，朗读下列单词，注意划线部分的发音。cake facegamelake latesaferace beheme wethese she eve bikefinekiterice time hidesize wife gosonohome nose hopejokenote use music cute computer pupil UK USAUN7.下列划线部分字母的发音相同吗？ (Y/N)Aa: 1) name bag () 2)grade thank () Ee: 1) hebed ()2) she egg ()Ii:1) bike sit ()2) k
