Is that you, John?
Yes, speaking. Tell Mary we'll be late for dinner this evening. I'm afraid I don't understand. Hasn't Mary told you? She invited Charlotte and me to dinner this evening. I said I would be at your house at six o'clock, but the boss want me to do some extra work. I'll have to stay at the office. I don't know when I'll finish. Oh, and by the way, my wife wants to know if Mary needs any help. I don't know what you're talking about. That is John Smith, isn't it? Yes, I'm John Smith. You are John Smith,the engineer,aren't you? That's right. You work for the Overseas Engineering Company, don't you? No, I don't. I'm John Smith the telephone engineer, and I'm repairing your telephone line.

是你吗，约翰？
是我，请讲。 你告诉玛丽，今晚吃饭将晚到一会儿。 恐怕我还不明白您的意思。 玛丽没有告诉你吗？ 她邀请我和夏洛特今晚去吃饭。 我说过我6点到你家，但老板要我加班。 我不得不留在办公室， 不知道什么时候才能结束。 喔，顺便问一问，我妻子想知道玛丽是否需要帮忙。 我不知道您在说些什么。 你是约翰.史密斯，对吗？ 是的，我是约翰.史密斯。 你是工程师约翰.史密斯，对吗？对。 你在海外工程公司上班，是吗？ 不，不是。 我是电话工程师约翰.史密斯，我正在修理您的电话线。
