Lesson 6 Percy Buttons 珀西·巴顿斯
I have just moved to a house in Bridge
Street. Yesterday a beggar knocked at my door. He asked me for a meal and a
glass of beer. In return for this, the beggar stood on his head and sang songs.
I gave him a meal. He ate the food and drank the beer. Then he put a piece of
cheese in his pocket and went away. Later a neighbor told me about him.
Everybody knows him. His name is Percy Buttons. He calls at every house in the
street once a month and always asks for a meal and a glass of beer.

知识笔记：
今日练习： [aʊ]
百度查得：
软腭：口腔上壁的后部，又叫后颚。
/aʊ/在下面单词中的发音：
mouse/maʊs/n. 鼠标
cloud/klaʊd/n. 云
town/taʊn/n. 城镇
south/saʊθ/n. 南方
pound/paʊnd/n. 英镑
drought/draʊt/n. 干旱
发音方法
1）学习该音发音方法请先学习/ɑː/和/ʊ/这两个单元音。
2）嘴巴放松张大，嘴唇向两侧分开。舌身放平，舌尖轻抵下齿，发/ɑː/。
3）然后嘴巴收圆合拢。舌尖离开下齿，舌身后缩，舌后部身软颚抬起，发音慢慢滑向[ʊ]。
注意：/aʊ/是个"开合双元音"，发音时口形由大变为小。音量由强到弱，由长到短，由清晰到含糊。
练习感悟：
今天在练习中特别注意了house的发音。但是不是很自然，发音之前会犹豫，老是想着找发音位置，还没有形成习惯，还需要大量练习。
