1 Lesson 1 A private conversation 私人谈话 2 ---------------------------------------- 3 Last week I went to the theatre. 4 I had a very good seat. 5 The play was very interesting. 6 I did not enjoy it. 7 A young man and a young woman were sitting behind me. 8 They were talking loudly. 9 I got very angry. 10 I could not hear the actors. 11 I turned round.I looked at the man and the woman angrily. 12 They did not pay any attention. 13 In the end, I could not bear it. 14 I turned round again. 15 'I can't hear a word!' I said angrily. 16 It’s none of your business,' the young man said rudely. 17 'This is a private conversation!'.
