摘要:
该初中英语课件聚焦元音字母a,e,i,o,u在重读开音节和闭音节中的发音规则,通过复习元音字母与音节概念导入,用“敞开/关闭的房间”比喻及拍手感受音节,搭建从元音字母到音节划分再到发音规则的学习支架,帮助学生理解开闭音节特征及元音发音差异。
其亮点在于融合视频观看、chant朗读、图片观察等多元活动,通过“门栓”等生活化比喻和cake(开音节)与cat(闭音节)对比练习,培养语言能力中的发音辨析和思维品质中的分析比较。自我检测题与分层练习提升学习能力,学生能直观掌握规则,教师可借助结构化资料高效教学。

Review & Say
Do you remember how many vowels (元音字母) there are? What are they?
Last time we learned how vowels sound in stressed open syllables (重读开音节). Do you still remember?
音节:是读音的最小单位。由音素构成。即元音的声音或元音和辅音声音的结合。
可以把音节比作“一个小发音单位”,说话时的发音也会分成一个个“小声音块”,每个“小声音块”就是一个音节。
比如妈妈(mā ma)有两个音节,苹果(píng guǒ)”也有两个音节;
英语里“bird(鸟)”是一个音节,“teacher(老师)”是两个音节(tea-cher)。“cat(猫)”就是一个音节,“apple(苹果)”是两个音节(ap-ple)。
简单说,一个音节就是我们读单词时,嘴巴用力一次发出的声音,可以通过拍手来感受:读一个音节拍一下手,拍几下就是几个音节。
开音节:就像“敞开大门的房间”,元音字母(a、e、i、o、u)没有被关上,能“舒展地”发自己本来的长音。
1.“元音字母在结尾”,比如“he(他)”,最后是元音e,没有辅音“把门”,e就发自己字母本身的音/iː/;还有“go(去)”,结尾是o,发字母本身的音/əʊ/,hi /aɪ/。
2.“元音字母+辅音字母+e”,比如“cake(蛋糕)”,e在最后不发音,前面的a就像“门没关严”,发自己本来的音/eɪ/;“like(喜欢)”里的i,也发字母本身的音/aɪ/。
开音节里的元音,读起来和字母本身的发音差不多,比较长、比较舒展.

五个元音字母的发音规则(一):
元音字母在重读开音节中的发音
在开音节中,元音字母发 ________ 的音。
字母本身
Today we will learn how vowels sound in stressed closed syllables (重读闭音节). Do you know what closed syllables (闭音节) are?
Lead in
Let’s know
以辅音字母(r和字母组合除外)结尾且中间只有一个元音字母的音节叫作闭音节。
英语重读闭音节就是重读音节为闭音节的音节。
closed syllables (闭音节)
闭音节:就像“被关上的小房间”,元音字母(a、e、i、o、u)
被关在里面啦。
一个音节里,元音字母后面跟着辅音字母(比如t、d、s、n这些,像“门栓”),把元音“锁”在中间,这时元音只能发短短的音,这就是闭音节。
“bag(书包)”:b是辅音,a是元音,g是“门栓”,a被关着,发短音/æ/(读得又短又快)。
bed(床)”:b和d是“门栓”,把e关在中间,e发短音/e/。
“hot(热的)”:h和t锁住了o,o发短音/ɒ/。
总结:闭音节=辅音字母+元音字母+辅音字母或者元音字母+辅音字母结尾,元音发短音,就像被“关起来”所以声音短, 对比开音节的“敞开门”(元音发长音)
简单说:
cat sit run put it
重读闭音节中元音字母不是发它本身的字母音,而是发短元音。

/æ/的发音:发音时舌尖抵住下齿根部,舌前端抬高,舌位比/e/发音位置更低,两唇延展平伸,口型扁平,开口中大。
例词:cat /kæt/、map /mæp/
元音字母a在重读闭音节中的发音:/æ/
/e/的发音:发音时舌尖抵住下齿根部,舌前端稍抬,舌位比/ɪ/发音位偏低,唇形中开,口型比/ɪ/较大。
例词:bed /bed/、pet /pet/
元音字母e在重读闭音节中的发音:/e/
/ɪ/的发音:发音时舌尖抵住下齿根部,舌前端抬高,舌两端抵住上齿,口型扁平。
例词:pig /pɪɡ/、sing /sɪŋ/
元音字母i在重读闭音节中的发音:/ɪ/
/ɒ/的发音:发音时口部张大,舌体降低并往后缩,嘴型微圆。
例词:hot /hɒt/、dog /dɒɡ/
元音字母o在重读闭音节中的发音:/ɒ/
/ʌ/的发音:发音时舌尖和舌两端快速触碰下齿,舌后端靠前部分稍抬,嘴型稍扁,开口中大,与/æ/嘴型相似。
例词:cup /kʌp/、duck /dʌk/
元音字母u在重读闭音节中的发音:/ʌ/
