老外教口音：如何说一口标准美式口音

bout this "r" sound coming from right at the back of the throat, back here. "Are there more birds?" Are there more birds?”同样，这是个很低沉的发音，你可能能感觉到这个“r”的发音发自于嗓子的后面，就在这后面。“Are there more birds?”Now our next sound is the vowel used in "cot", like where a baby sleeps, and "caught", when you catch hold of something."Cot" and "caught". They're different sounds in the British English accent, "cot" and "caught", but for most Americans, they're the same. "Cot" and "caught".我们下一个发音是“cot”里的元音，（cot）就是婴儿睡的摇床，还有“caught”里的元音，（caught）就是你抓住什么东西。“cot”和“caught”，它们在英式口音里是完全不同的发音，但是对美国人而言，它们是一样的。Have a listen to this: "He got caught by the long arm of the law." "He got caught by the long arm of the law." So that "got" and "caught" are the same, and "long" and "law" have the same sound in the middle.听听这个：“He got caught by the long arm of the law.”He got caught by the long arm of the law.所以“got”和“caught”，“long”和“law”中间的发音都是一样的。Finally, let's listen to the "t" and "d" sounds for Americans. We say them quite precisely, like this: "butter", "letter". But they're quite often flapped for Americans so that there's not much difference between the "t" and the "d". "Butter", "letter", "master". "Witty banter about the Star-Spangled banner."最后，让我们来听听美国人“t”和“d”的发音。我们（英式口音）发音相当精确，比如“butter”，“letter”。但是美国人通常很快带过这个音，所以“t”和“d”的发音没什么区别。“butter”，“letter”，“master”。Listen to this sentence: "Witty banter about the Star-Spangled banner." So there's no difference between "banter" and "banner", they're both "banner". And "the medal for bravery was made of metal." "The medal for bravery was made of metal." So that's "medal" and "metal" both become "medal".听听这句句子：“Witty banter about the Star-Spangled banner.”“Witty banter about the Star-Spangled banner.”所以“banter”和“banner”之间没什么不同，都是“banner”。同样，“the medal for bravery was made of metal.”“the medal for bravery was made of metal.”“medal”和“metal”都变成了“medal”。
