Passage Two
篇章结构
本篇讲述医生发现用纸记录下的东西比口语交流的信息更加准确和稳定。问题源自一位医生在对一个孩子的家庭口述交待了出院后的注意事项之后，发现这些亲属们竟然记不清到底医生讲了些什么，于是医生决定在以后交待注意事项的时候要把这些内容全印成纸质的东西，因为纸质的东西比口语更可靠。

难句解析
1. Also listening to her were a half a dozen other family members.
【解析】此句为倒装句，强调listening to her，主语为a half a dozen other family members。正常语序为：A half a dozen other family members were also listening to her.
2. All of them had heard the simple instructions I have given just a few hours before, but they have three or four different versions.
【解析】本句两分句由连词but连接，had heard为过去完成时，表示在家人问玛雅医生之前就发生了此动作。I have given just a few hours before做定语修饰the simple instructions，省略连接词that。
试题详解

C) Who should take care of the child at home. C) 谁在家照顾孩子。
D) When the child would completely recover. D) 什么时候这个孩子能完全恢复。
【听音指导】浏览四个选项，应注意到都为wh-开头的疑问词，且提到了医生和孩子，take care of 以及recover，可初步推测此题涉及的场景为医院，病人为孩子。
【正确项分析】问题为孩子的家人因为什么而争论，原文为the family asked her to settle an argument they’d been having over exactly what advice she had given，意为亲属们就医生到底讲过什么建议争论不休，问医生如何解决。选项B中的instructions与原文的advice同义，选项B正确。
30. A) She encourages them to ask questions when in doubt. A) 她鼓励他们拿不准时就提问题。

C) She has them act out what they are to do at home. C) 她让他们把将在家里做的事情表演出来。
D) She asks them to repeat what are supposed to do. D) 她让他们复述要做的事。
【听音指导】由第一题的选项可很有把握地推测she指代的是Doctor Myer，而与医生相对的多半为病人。注意关键词ask question，write down，act out和repeat。
【正确项分析】玛雅医生如何确定病人完全明白了自己的建议呢?原文为She asks them to tell her what they think they are supposed to do，原文的 tell her与选项D中的关键词repeat一致，选项D为正确答案，
