音标辅音课件-5(共73张PPT)

❖ 4. 爆破音+舌侧音
❖ 如：little, at last hard life 等中得斜体部分也属不完全失去爆破。也要注意：这时舌尖紧贴上齿龈，同 样不可离开（一离开就必然会加进一个/ə/音），让气流从舌两侧冲出。细细体会，反复练习
/s/后面爆破辅音得送气问题
❖ 1. 英语中/s/音后面、元音前面得爆破清辅音（如/k/、/p/、/t/等）在实际发音中要明显减少送气，听 来就像与它对应得浊辅音，但实际上发该音时声带并无明显振动。它之所以由送气音变为不送气音，主 要是因为它前面得/s/音已经送气很强。如：
摩擦辅音/θ/和/ ð /
❖ 发音要领 ❖ 舌尖轻触上齿，并须略微露出齿外，气流由舌齿间泄出，摩擦成音 ❖ /θ/是清辅音，送气强，声带不振动 ❖ / ð /是浊辅音，送气弱，声带振动

摩擦辅音/s/和/z/
❖ 发音要领 ❖ 舌端贴近上齿龈（不要贴住），气流从舌端齿龈之间泄出，摩擦成音。 ❖ 注意舌位应比汉语中得“s”（斯）音略靠后，发出得音听起来不如汉语得“斯”音那样清脆。 ❖ 上下牙齿及其接近 ❖ /s/是清辅音，送气强，声带不振动 ❖ /z/是浊辅音，送气弱，声带振动

摩擦辅音/f/和/v/

❖ Sky 注音为/skai/,但听起来则像/sgai/一样 ❖ Stone 注音为/stəun/,但听起来如/sdəun/ ❖ Strong 注音为/strɔ:ŋ/,但听起来如/sdrɔ:ŋ/
爆破辅音/t/和/d/
❖ 发音要领 ❖ 舌尖紧贴上齿龈，但不接触上齿，形成阻碍，然后突然离开，让气流冲出口腔。 ❖ /t/是清辅音，送气，声带不振动。 ❖ /d/是浊辅音，不送气，声带振动。
❖ 注意：失去爆破绝不等于前一个爆破音不存在了，读得时候可以不管它了。在读后一个辅音之前，先要 老老实实得用相关得发音器官摆好前一个爆破音得发音姿势，做发音准备，稍稍停顿后再直接发下面得 爆破音。
❖ 失去爆破分以下几种情况 ❖ 1. 爆破音+爆破音 ❖ 如:a flat tire, cup-board, blackboard, Red Cross等中得斜体部分一律失去爆破。这叫做完全失去爆破。 ❖ 2. 爆破音+摩擦音或破擦音 ❖ 如: a sad story, a nonstop flight, recite the poem, a good chance, odd jobs等中得斜体部分只有轻微得爆
❖ Tong twister ❖ Good, better, best, ❖ Never let it rest, ❖ Until good is better, ❖ And better best.
爆破辅音/k/和/g/
❖ 发音要领 ❖ 舌后部上台紧贴上颚，形成阻碍，然后突然离开，让气流冲出口腔 ❖ /k/是清辅音，送气，声带不振动 ❖ /g/是浊辅音，不送气，声带振动
❖ Grab a bite ❖ Pride and prejudice
❖ Probably. ❖ The big building is two blocks away
失去爆破
❖ 当一个爆破音后面紧接着另一个爆破音或摩擦音、或破擦音、或鼻音、或舌侧音时，前一个爆破音不发 生爆破或不完全发生爆破，这种现象就叫做失去爆破。

摩擦辅音/ʃ/和/ʒ/
❖ 发音要领 ❖ 舌前端靠近上齿龈后部，舌两侧向上颚卷起，舌中间形成一条狭长得通道，气流通过时摩擦成音。 ❖ 双唇向前突出，略成圆形。 ❖ /ʃ/是清辅音，发音时要送气，声带不振动 ❖ /ʒ/是浊辅音，发音时只有微弱气流泄出，摩擦在舌端，但不要卷舌，声带振动
破。这叫做不完全失去爆破。
❖ 3. 爆破音+鼻辅音
❖ 如：garden, good morning, lightning, good night等中得斜体部分也只发生不完全爆破。注意：许 多人不会发这个音，他们实际上还是把“garden”读作/’gardən/而不是/’gardn/，也就是说，他们 在最后两个音之间加进了一个/ə/音。发后一个音节/dn/得音时，舌尖紧贴上齿龈，不要离开（一离开就 会有爆破，而且从/d/到/n/舌位不需变化），让气流通过鼻腔冲出。细细体会，反复练习。
双唇爆破辅音/p/和/b/
❖ 发音要领 ❖ 双唇紧闭，然后突然分开，让气流冲出口腔 ❖ /p/是清辅音，送气，声带不振动 ❖ /b/是浊辅音，不送气，声带振动Fra bibliotek❖ /p/
