18、单词可以有一个、两个三个或更多的音节。就像我们刚看到的单词 driveway 有两个音节,句子 Drive him away 有四个音节。同时，音节又是英语发音节奏的最基本的单位。何谓“重读音节”？如果一个英语单词中拥有两个或两个以上的音节，其中一个音节会比其周围的音节要响亮些。重读音节通常在词典中有所标注。例如，单词 driveway 的第一个音节就是重读音节，而它的第二个音节就是非重读音节。英语中的重读音节在发音过程中往往要比非重读音节要长一些，响亮一些，同时音调也稍高一些。例如，“banana”一词有三个音节。第一个音节是非重音，所以发音所需时间比较短。第二个音节是重读，所以元音/:/发

19、的比较长，清晰响亮。第三个音节同样属非重音，所以发音所需时间也很短。可见，重读音节与非重读音节分别有以下特征：重读音节:声音响亮 延续时间较长 音调较高非重读音节:1.延续时间较短 2.元音发音弱化英语话语节奏英语话语节奏：学会发好每一个英语音素，是学好英语语音的基础，正确的发音在语言交流中非常重要。然而，语音的组合方式对于听者的理解也起着至关重要的作用。英语的话语节奏就是其中之一。何谓“英语话语节奏”？节奏在我们的日常生活中无所不在：滴答转动的钟表声，砰砰不停的心脏跳动，游泳的划水节拍，优美诗句和音乐的韵律，这些都是节奏的体现。话语节奏与前面我们所提到的日常生活中显而易见的节奏不同之处在于：

20、语言中的话语节奏不是那么明显与绝对。语言中的节奏特征是由一连串音节的长短来体现的。有一些语言的话语特点是：每一个音节的音长呈大致相同的趋势，这种音节彼此距离大致相等的现象被称为“以音节定时”节奏。汉语的话语节奏就有这样的倾向。例如，当我说：“面包加牛奶”，这里含 5 个音节，所需的时间暂且定为 5 个时段。如果我要说：“一片面包加一杯牛奶”，这里含 9 个音节，所需的时间就是 9 个时段。英语的话语节奏则显不同的趋势。例如，在“bread and milk”短语中，音节数是三个，其中“bread”与“milk”是重读音节。在“some bread and somemilk”这一短语中，音节数是

21、 5 个，其中重读的也是“bread”与“milk”。虽然这两个短语的音节数不同，但是在话语中，它们所需的时间却是大致相同的，因为它们有一个共同点：重读音节数相同。这种重读音节彼此距离相等的现象就是“以重音定时”节奏。掌握这一英语话语的节奏规律。对于提高我们英语口语的-第 5 页流利程度和自然程度以及英语听力理解快速解码的能力至关重要。正因为如此，我们将重音与节奏的学习放在中心与突出的位置，从第一单元的概念介绍开始，贯穿整个语音课程学习的始终。-第 6 页Unit 2Purpose:The students will learnthe stop consonants in English.Ob

44、；/t/和/d/的发音部位是舌尖和齿龈；/k/和/发音时，则是用舌后部触软腭形成阻塞而爆破生音。其中/p/，/t/和/k/是清辅音，因为发这三个音时声带无需-第 10 页振动。相反的，/b/，/d/和/在发音时，声带振动，是浊辅音。/p/和和/b/当你发/p/和/b/两音时，双唇合拢而形成阻塞，然后让气流冲决阻碍，爆破生音。这两个音可出现在词首、词中和词尾三个部位，/p/和/b/在不同的语音环境中有不同的变体：/p/的音位变体/p/在词首且在重读音节中时，是送气音如 poke；当处于词尾时，可能失去爆破，如 top tea；在/s/后形成辅音连缀时，/p/在发音时不送气，如 spot；当两个/

45、p/相邻时，无需产生两次爆破，而只是延长发音的时间，如 stop Pete；当/p/后紧跟着的是鼻音时，此时爆破不在口腔，而在鼻腔，就是我们通常说的“鼻腔爆破”，如 Stop him；/b/的音位变体：当处于词尾时，不完全爆破，如 rob the man；当两个b相邻时，无需产生爆破，只是延长发音时间，如 rob Bob；/b/在鼻音前时，爆破不在口腔，而在鼻腔，如 rob him；/t/和和/d/t/和/d/是齿龈爆破音.发这两个音时，用舌尖抵齿龈成阻，让气流爆发而出。/t/的音位变体/t/在词首且在重读音节中时，是送气音如 tape；当处于词尾时，可能失去爆破，如 sit still；在/

46、s/后形成辅音连缀时，/t/在发音时不送气，如 stop；当处于/之前时，呈齿音化发音，如 eighth；当/t/后紧跟着的是鼻音时，此时爆破不在口腔，而在鼻腔，就是我们通常说的“鼻腔爆破”，如 button；当处于两个元音之间时，/t/听起来近似闪音，如 letter；当/t/位于成音节/n/或/l/前时，便成了声门爆破音，如 little；当两个/t/相邻时，无需产生两次爆破，而只是延长发音的时间，如 let Tim;当处于辅音组合/tr/中时，发音兼具爆破与摩擦的特征，如 train；/d/的音位变体：当处于齿间音（如/）之前时，呈齿音化发音，如 width；当处于词尾时，不完全爆破，如

47、 Dad said so.当与/l/组合时，成为舌侧爆破音，如 padlook；/d/在鼻音前时，爆破不在口腔，而在鼻腔，如 breadn butter;当两个/b/相邻时，无需产生爆破，只是延长发音时间，如 sad Dave当处于辅音组合/dr/之中时，发音兼具爆破和摩擦的特征，如 drain。/k/和和/发/k/和/两音时，用舌根顶住软腭堵住气流的出路，然后舌根猛地离开软腭使气流爆发而出。/k/是清辅音，/是浊辅音。-第 11 页/k/的音位变体/k/位于词首，且在重读音节中时，是送气音，如 keep；当处于词尾时，可能失去爆破，如 take three；在/s/后形成辅音连缀时，/k/在

48、发音时不送气，如 sky当两个/k/相邻时，无需产生两次爆破，而只是延长发音的时间，如 take Kim;当/k/后紧跟着的是鼻音时，此时爆破不在口腔，而在鼻腔，就是我们通常说的“鼻腔爆破”，如 beacon;当与/l/音组合时，成为舌侧爆破音，如 clock；后跟前元音时，/k/的发音部位前移，如 keen；位于成音节/n/时，便成了声门爆破，如 bacon；位于圆唇音之前时，发音时亦呈圆唇，如 quarter./的音位变体当处于词尾时，不完全爆破，如 lag behind;当两个/相邻时，无需产生爆破，只是延长发音时间，如 big grapes当与/l/组合时，与成为舌侧爆破音，如 gla

49、d；/在鼻音前时，爆破不在口腔，而在鼻腔，如 pig and goat;后跟前元音时，发音部位前移，如 geese;位于圆唇音之前时，发音时亦呈圆唇，如 goose.发音难点解析发音难点解析中国学生在学习英语爆破音时要注意的问题主要有以下两点：一、爆破音的学习，就发音部位来说，并不难掌握：英语的爆破音与汉语的声母（b，p，d，t，k，g）极为相近。所不同之处主要体现在发音方法上。总的说来，英语的三对爆破音的区别特征是清辅音和浊辅音；而区别汉语三对声母的特征则是送气音与非送气音。当英语的爆破音位于词首时，清辅音的送气比汉语的对应音更为有力；浊辅音一般只有轻微的声带振动。当英语的爆破音位于词尾时，

50、爆破可能非常地轻微，此时，帮助辨别清浊辅音的一个重要特征就是位于爆破音前的元音的长度。例如，在相似的语音环境中，need 中的/i:/通常比 neat中的/i:/稍长一些。另外，当浊辅音位于两个元音之间时，声带振动则是必须的。二、在学习中要注意的另一个问题是这三对爆破音的音位变体。这些音位变体的主要形式我们已经接触过。例如，什么时侯爆破音会失去爆破：take them；鼻腔爆破音应怎么发：garden；旁流爆破音应怎么发：people；在辅音连缀中，当/p t k/出现在/s/之后，“送气”会减弱，如 speak,sky,star。掌握了以上发音方法，我们就能正确地发好英语的爆破音了。-第 1
