　　In her early days as an emergency room physician, Doctor Joanna Mayer treated a child who had suffered a second degree burn. After the child had been treated and was being prepared for discharge, Doctor Mayer talked to the parents about how they should care for the child at home. Also listening to her were a half a dozen other family members. A few hours later, when she came to say goodbye, the family asked her to settle an argument they’d been having over exactly what advice she had given. “As I talked to them, I was amazed.” she said, “All of them had heard the simple instructions I have given just a few hours before, but they have three or four different versions. The most basic details were unclear and confusing. I was surprised, because these were intelligent people.” This episode gave Doctor Mayer her first clue to something every doctor learns sooner or later---- most people just don’t listen very well.

　　Nowadays, she says she repeats her instructions, and even conducts a reality check with some patients. She asks them to tell her what they think they are supposed to do. She also provides take-home sheets which are computer printouts tailored to the patients’ situation. Doc. Mayer’s listeners are not unusual. When new or difficult material is presented, almost all listeners are faced with a challenge because human speech lacks the stability and permanence of the printed word. Oral communication is fast-moving and impermanent.

　　29. What did the child’s family members argue about in the hospital?

　　30. What does Doc. Mayer do to insure her patients understand her instructions?

　　31. What does the speaker say about human speech?

　　乔安娜•玛雅是一名急诊室医生。早年，她曾医治了一名二度烧伤的孩子。这个孩子接受完治疗准备出院时，玛雅医生告诉孩子父母在家如何照顾孩子，在场的还有六位家庭其他成员。几小时后，当她来与孩子再见的时候，孩子一家请她解决争论，他们一直争论她的医嘱到底是什么。“因为我已经告诉过他们，所以我很惊讶。”她说，“他们所有的人都在短短几小时前听到了我给出的简单的医嘱，但是他们有三、四个不同的版本。最基本的细节都不清楚且很困惑。我很吃惊，因为这些是聪明人。”这一段插曲给了玛雅医生第一个线索，而这迟早每个医生都会懂得，即大多数人听的不准确。

　　如今，玛雅说她反复重复医嘱，甚至对一些病人进行现场核查。她要他们告诉她他们应该做的事。她还根据病人的情况提供可带回家的打印文本。玛雅医生的听众都是正常人。当面对新资料或难度较大的资料时，几乎所有的听众都会面临挑战，因为人类口语缺乏书面文字的稳定性和永久性。口头交流速度快但持续时间短。

　　29. 孩子的家庭成员在医院里争论的是什么?

　　30. 为确保病人明白她的医嘱，玛雅医生做了什么?
