Lesson19 Sold out
'The play may begin at any moment,' I said.
'It may have begun already,' Susan answered.
I hurried to the ticket-office. 'May I have two tickets please ?' I asked.
'I'm sorry, we've sold out,' the girl said.
'What a pity!' Susan exclaimed.
Just then, a man hurried to the ticket-office.
'Can I return these two tickets?' he asked.
'Certainly,' the girl said.
I went back to the ticket-office at once.
'Could I have those two tickets please ?' I asked.
'Certainly, 'the girl said, 'but they are for next Wednesday's performance. Do you still want them?
'I might as well have them,' I said sadly.

知识笔记：
单词：1、 exclaim:呼喊，惊叫；
音标：/eə/ :wear，bear；
发音方法：学习该音的发音方法请先学习/e/和/ə/这两个单元音。2）首先先发前元音/e/，同时舌尖轻触下齿。3）然后很快滑向/ə/音，发音过程中双唇半开。注意：/eə/是个"集中双元音"，发音/e/时嘴角向两边拉，滑向/ə/音收小，口型由大变小。
练习感悟：逐句跟读了3遍，反复听原音，自己录音的时候语调还是和原音不同，不太掌握重音。
原音时长：74s
录音时长：73s
练习时长：45min
