问答题

[听力原文] LawsBefore laws were written, there was no sure way of knowing what was permitted and what was forbid- den. One judge might apply one set of rules to a case while another judge might apply completely different rules to a similar case. It all depended on the personal judgment of one person. Today we follow the custom of recording our laws. Rules passed by our lawmakers are printed and avail- able for everyone to see. Unless laws are publicly available, we do not regard them as binding. Each of us is subject to many different sets of laws. Some laws say what is permitted, such as how fast you may drive. Other laws say what is required, such as paying a federal income tax. Still other laws say what is prohibited, such as smoking in elevators. In the United States, federal laws apply to everyone and state laws apply to activities within each state. [听音关键] 本文介绍了法律的形成及法律的功用，关键词有：Before laws were written...personal judgment；Today...laws；different sets of laws... Some...permitted... Other...required... Still other... prohibited： US... federal laws... state laws。[听写难点] ①动词的过去分词形式，如要双写辅音加-ed的词在文中有多个：written，permitted，forbidden；②难词，如：completely完全地，available可利用的，binding有约束力的，prohibited禁止，elevators电梯。[画龙点睛] 听第一遍时要善于抓住文中表示结构层次的词来进行理解。第二、三遍书写时可以利用一些符号或数字来代替，如permitted可以写成√，forbidden可以写成×，one写成1。第四遍时进行查漏补缺。最后两分钟修改的时候补充完整简写和符号等。
