Lesson25 Do the English speak English?

I arrived in London at last. The railway station was big, black and dark. I did not know the way to my hotel, so I asked a porter. I not only spoke English very carefully, but very clearly as well. The porter, however, could not understand me; I repeated my question several times and at last he understood. He answered me, but he spoke neither slowly nor clearly. 'I am a foreigner,' I said. Then he spoke slowly, but I could not understand him. My teacher never spoke English like that! The porter and I looked at each other and smiled. Then he said something and I understood it. 'You'll soon learn English!' he said. I wonder. In England, each man speaks a different language. The English understand each other, but I don't understand them! Do they speak English?

任务配置：L0+L1+L4

知识笔记：

1.朗读(L0): 提交录音的时长为1分23秒，原音正文部分1分23秒左右。

2. 音标(L1):question/ˈkwɛsʧən/  teacher  /ˈtiːʧə/  each /iːʧ/

ch  /ʧ/

1）双唇微张向前突出，略成圆形。

2）舌尖和舌端抬起贴住上齿龈后部，憋住气。

3）然后舌尖稍稍下降，气流从舌和齿龈间的狭缝中冲出，摩擦成音。

4）/t∫/是个清辅音，声带不震动。/tʃ/这个音和汉语拼音中的声母ch很相近，很多北方同学会用"吃"代替/tʃ/是不正确的，一些南方同学会把/tʃ/和汉语拼音中的声母q混淆，也是极不正确的，应注意区分它们的异同。

3. 今天是第二十五天: 学英语在发音时嘴要尽量张开，声音要以靠下为主。自己以前发音听起来比较浅的原因，主要是声音比较靠上，故听起来也比较飘。
