练习材料：Lesson 15​ Good news

The secretary told me that Mr. Harmsworth would see me. I felt very nervous when I went into his office. He did not look up from his desk when I entered. After I had sat down, he said that business was very bad. He told me that the firm could not afford to pay such large salaries. Twenty people had already left. I knew that my turn had come. 'Mr. Harmsworth,' I said in a weak voice. 'Don't interrupt,' he said. Then he smiled and told me I would receive an extra thousand pounds a year!

任务配置：L0+L4

知识笔记: “did not look” “had sat down” “could not”发生辅辅轻音化音变， “Don’t interrupt”同时发生辅元连音音变和辅辅轻音化音变， “said in a”发生辅元连音音变。

练习感悟：嘴皮子快要磨破了，如果要做到语速和语调听起来像课本录音一样，需要注意力高度集中。
