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 person speaks a different language. The English understand each other, but I don't understand them! Do they speak English?

知识笔记：
porter
美 /'potər/
a person whose job is to be in charge of the entrance to a hotel, large building, college, etc. 门卫；门房
the night porter 夜班门卫
音标专练：[l]
发音要点：
舌尖紧贴上齿龈；
舌前部抬起靠近硬腭；
发音时气流从舌的两侧泄出；声带振动。
[l]是英语中唯一一个舌边音，也就是说发音时气流通道中央阻塞，在阻塞处的两边留下通道让气流自由通过的音。
[l]这个音可以根据它所出现的位置不同发出两种不太完全一样的音：
在元音前发light [l]，在下一个音即将发出时舌头离开上齿龈，迅速下落；
在元音后发dark [l]，类似ou。
练习感悟：l的前置发音没得问题，后置发音直到最近才有所领悟-舌身后缩。看瑞秋视频对练习l很有帮助。
