内容正文:

Unit 1 This is me! Pronunciation 1 ★学习目标 掌握元音字母a, e, i, o, u在开音节中的发音规则及对应音标(/eɪ/, /iː/, /aɪ/, /əʊ/, /juː/),能准确朗读相关单词和句子。 通过观察例词归纳开音节拼读规律,培养分析、推理及总结语音规则的能力。 运用发音规则自主拼读生词,借助语音知识辅助单词记忆与拼写,提升自主探究能力。 体会英语语音的韵律美,在猜谜等互动活动中增强用英语介绍人物与交流的意识。 ★教学重难点 识记并准确发出五个元音字母在开音节中的读音;区分开音节两种形式(绝对开音节与相对开音节)。 将发音规则迁移运用到新词认读中;准确辨析易混淆的元音发音(如/uː/与/juː/的区别)。 Warming up They are Vowels Look at these letters. What are they? 5 Look at the picture. What are they doing or holding? Can you read these words aloud? Do the vowel letters in these words sound the same as their letter names? Why? Reading Read the following words. Pay attention to the sounds of the letters a, e, i, o and u. name face game age late be he me we these fine hi write time kite old home no nose close computer cute music student use /eɪ/ /i:/ /aɪ/ /əʊ/ /ju:/ Observe the words in the table and find out their spelling rules. name face game age late be he me we these fine hi write time kite open home no nose close computer cute music student use 9 Open syllables be, he, hi, no, mu/sic … name, these, fine, home, cute … name face game age late be he me we these fine hi write time kite open home no nose close computer cute music student use 10 The sounds of the vowel letters in open syllables are the same as the sounds of the letters themselves. Aa—/eI/—name Ee—/iː/—be Ii—/aI/—write Oo—/əʊ/—home Uu—/juː/—cute 11 Try to use the rules to read the words. Pay attention to the sounds of the vowels. game, plane, face, grape, late, … /eI/ Chinese, Japanese, … /iː/ tiger, nice, time, ride, … /aI/ rose, go, close, note, … /əʊ/ university, duty, huge, … /juː/ 12 Why do we need to learn the sounds of the vowels in open syllables? 1. It helps us read some new words correctly. 2. It helps us spell some new words easily. 3. It helps us remember some new words over a long time. 13 Read the words below. Then put them in the correct sound groups. grade make she these like white hello those music use /eɪ/ /aɪ/ /əʊ/ /ju:/ /i:/ grade she hello like make music those use white these 14 Look at the groups of words. Try to read the new words according to the sound of the word in the centre in each group. a /eɪ/ i /aɪ/ o /əʊ/ 15 1. We have the same hobbies. 2. My classmates are all very nice. 3. Sandy likes listening to piano music. 4. Simon and Amy go to school by bike. 5. These students go home by bus. /i:/ /eɪ/ /eɪ/ /aɪ/ /aɪ/ /əʊ/ /ju:/ /aɪ/ /eɪ/ /əʊ/ /aɪ/ /i:/ /ju:/ /əʊ/ /əʊ/ Read the following sentences. Pay attention to the sounds of the letters in bold. 16 Pronunciation 17 /eɪ/ 发音类型: 双元音(由 /e/ 滑向 /ɪ/) 口型变化: 起始时嘴巴自然张开,舌尖抵下齿,舌前部稍抬起;然后下颌逐渐上移,嘴角向两侧微拉,口型从半开滑向微闭。 关键要领: 这是一个滑动音,不能发成单一的“诶”。要有明显的从 /e/ 到 /ɪ/ 的过渡感,前长后短,前重后轻。 常见误区: 避免发成汉语拼音的“ei”或单元音 /e/,尾音 /ɪ/ 不可省略。 /iː/ 发音类型: 长元音 口型状态: 嘴唇向两侧用力拉开,呈扁平状(像微笑),上下齿之间仅留微小缝隙。舌尖抵住下齿背,舌前部尽量抬高靠近硬腭。 关键要领: 肌肉保持紧张,声音拉长且稳定,气流通道窄而均匀。 对比提示: 与短元音 /ɪ/ 相比,/iː/ 嘴角拉得更开、舌位更高、肌肉更紧、发音更长。 /aɪ/ 发音类型: 双元音(由 /a/ 滑向 /ɪ/) 口型变化: 起始时嘴巴大张,舌尖轻触下齿,舌身放平偏低;然后下颌迅速上提,嘴角向两侧收拢,滑向 /ɪ/ 的位置。 关键要领: 开口度是五个音中最大的。滑动过程要流畅饱满,起点 /a/ 要充分打开,终点 /ɪ/ 要清晰到位。 常见误区: 不要发成汉语“爱”,起始音应是口腔完全打开的 /a/,而非靠后的 /ɑ/。 /əʊ/ 发音类型: 双元音(由 /ə/ 滑向 /ʊ/) 口型变化: 起始时嘴巴微张,唇形自然中性,舌位居中放松;然后双唇逐渐收圆并向前突出,舌后部抬起,滑向 /ʊ/。 关键要领: 这是唯一一个唇形由扁变圆的双元音。起始的 /ə/ 非常短促放松,重心落在滑动过程和尾音的圆唇上。 注意: 英式发音为 /əʊ/,美式发音记作 /oʊ/,起始口型稍圆一些,但滑动趋势一致。 /juː/ 发音类型: 辅音+长元音组合(/j/ + /uː/) 口型变化: 先发半元音 /j/(舌前部抬向硬腭,类似汉语“衣”的起始动作),随即双唇迅速收圆前突,舌后部抬高,发出长元音 /uː/。 关键要领: /j/ 只是一个极短的过渡,核心是后面的 /uː/。双唇要明显前突成小圆形,肌肉紧张,声音拉长。 重要区分: 在字母 u 的开音节中,有时发 /uː/(如 blue, true),有时发 /juː/(如 cute, use)。本课重点练习的是带 /j/ 头的 /juː/,注意不要丢失前面的 /j/ 音。 Exercise 28 单词归类题 将下列单词按发音归类填入对应音标下方: grade, she, hello, like, make, music, those, use, white, these /eɪ/ /iː/ /aɪ/ /əʊ/ /juː/ grade, make she, these like, white hello, those music, use 选出下列每组单词中画线部分发音不同于其他单词的选项。 ( )1. A. number B. pupil C. use D. computer ( )2. A. face B. game C. name D. apple ( )3. A. she B. we C. desk D. these ( )4. A. no B. from C. nose D. those ( )5. A. tennis B. nice C. wife D. like A D C B A Summary 核心规则:元音字母 a, e, i, o, u 在开音节(绝对/相对)中,发音与字母本音相同(/eɪ/, /iː/, /aɪ/, /əʊ/, /juː/)。 实践应用:运用开音节发音规律,实现见词能读、听音能写,提升单词拼读与记忆效率。 学习价值:掌握语音规则是自主朗读生词、准确拼写和长期记忆单词的关键基础。 32 Homework Homework Review: Memorize the sounds of vowels (a, e, i, o, u) in open syllables and read the word list aloud.
