Pay attention to the stresses, weak forms and rhythms. We’re 'Going 'Green We're going to 'take 'care of the 'earth. We can go 'green at 'home or 'school. Re'ducing: 'Turn off the 'water when we’re 'brushing our 'teeth. 'Pull out 'plugs when they’re 'not in 'use. And 'don’t for'get to 'pick up 'trash. Re'using: If we can 'use the stuff a'gain, 'don’t 'throw it out. We can re'use 'bottles, 'bags, and con'tainers. Do'nate 'old 'toys and 'clothes, so someone else can 'use them. Re'cycling: 'Just re'using some 'things is not en'ough. Re'cycle them to make 'new 'things, like 'paper, 'cans, 'metals and 'plastic. 一、弱读式规则 (Weak form Rules) ‌‌·弱读是功能词（如介词、冠词、助动词等）在非重读时的简化发音，其核心在于 ‌元音弱化为 /ə/‌ 或 ‌辅音省略‌，使句子更流畅。‌ ‌·功能词弱读‌：冠词、介词、代词等常弱化（如 “‌a‌ cup ‌of‌ tea” 中 “a”和 “of”弱读为 /ə/ 和 /əv/）。 规律‌： ‌·弱读多出现在 ‌非强调位置‌（如句子中间）； ‌·句首/句末或强调时需用强读（如 “‌Of‌ course!” /ɒv/）。 The rules of weak form and rhythm ‌单词‌ ‌强读形式‌ ‌弱读形式‌ ‌示例‌ ‌to‌ /tuː/ ‌/tə/‌ “go to sleep”→ /ɡəʊ tə sliːp/ ‌for‌ /fɔːr/ ‌/fər/‌ “tea for two” → /tiː fə tuː/ ‌a/an‌ /eɪ/ /æn/ ‌/ə/ /ən/‌ “an apple” → /ən ˈæpl/ ‌of‌ /ɒv/ ‌/əv/‌ “cup of tea” → /kʌp əv tiː/ ‌and‌ /ænd/ ‌/ənd/ 或 /ən/‌ “bread and butter” → /bred ən ˈbʌtə/ ‌can‌ /kæn/ ‌/kən/‌ “I can go” → /aɪ kən ɡəʊ/ ‌he/his‌ /hiː/ /hɪz/ ‌/iː/ /ɪz/‌ (省略 /h/) “Tell him” → /tel ɪm/ 常见弱读形式‌ Weak form and Rhythm 二、节奏规则 (Rhythm Rules) 英语是重音计时语言（stress-timed）‌：重读音节之间的时间间隔趋近等长，非重读音节需压缩发音以匹配节奏。 ·重音等距性‌ 无论非重读音节数量多少，相邻重音间隔时长相似： “‌Walk‌.”（1音节） ≈ “‌I‌ can ‌walk‌.”（3音节） ≈ “‌It‌ is ‌pos‌sible to ‌walk‌.”（7音节） 重读音节（黑体）间的时间差基本一致。 ‌·非重读音节加速压缩‌ 重音之间音节越多，发音越快且弱化越明显： “The ‌book‌ is ‌on‌ the ‌desk‌.” → 非重读部分（the, is, the）需快速连读：/ðə bʊk ɪz ɒn ðə desk/ ·节奏单位（音步）‌ 每个节奏单位以 ‌重读音节开头‌，后续非重读音节依附于该重音： “◯ ‌Teach‌ ◯ the ◯ ‌chil‌dren ◯ ‌how‌ ◯ to ◯ ‌read‌.” （◯ 表示非重读音节依附于后方重音） 核心特征‌ 弱读与节奏的相互作用‌ ‌现象‌ ‌示例‌ ‌发音效果‌ ‌弱读+连读‌ “It ‌is‌ a ‌book‌.” /ɪt_ɪ_zə bʊk/（连读：t-i-zə） ‌重音间距控制‌ “‌Tell‌ me the ‌sto‌ry.” 重音 ‌Tell‌ 与 ‌sto‌ 间隔固定，弱读词（me, the）压缩发音 ‌弱读维持节奏‌ “I ‌want‌ to ‌go‌.” /aɪ wɒn(t)ə ɡəʊ/（to弱化为 /tə/，缩短时长） ⚠️ ‌常见错误‌：· 过度强调功能词（如 “I ‌AM‌ a student”），破坏节奏自然性；· 忽略弱读导致音节时长失衡（如逐字慢读 “I want to go home”）。 We learn: 1. 借助听、说活动，正确描述环境保护the three Rs(reduce,reuse and recycle) 的方法； 2. 运用所学语言知识分享自己对环境污染的看法和建议； 3. 利用连读、重读、弱化和节奏来正确朗读对话和文章。 We can: 1. 运用所学语言知识分享交流自己对环境污染的看法和建议; 2. 利用连读、重读、弱化和节奏来正确朗读对话和文章。 Summary Need to do Choose to do use the important phrases and sentences to talk about how to be a greener person in your daily life; master the rules of pronunciation fluently.
