初一英语音标教学案(修改).doc

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 au i 3.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 joke 2) these he we me3) bike fine kite nice 4) 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 face game lake late safe racebe he me we theseshe evebike fine kite rice timehide sizewife go so no home nosehope joke noteusemusiccutecomputerpupilUK USA UN7.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) he bed ( ) 2) she egg( )Ii: 1) bikesit ( ) 2) kite this( ) Oo:1) go not ( )2) Helloclock( )Uu:1) usecup ( ) 2)studentbus ( )8.归纳 ：1）.元音字母在重读开音节的读音a_ e_ i_ o_ u_2）.重读开音节的定义_【达标检测】一、找出划线部分发音不同的选项。（ ）1.
