1. It's a self-examination that has, at various times, involved issues of responsibility, creative freedom and the corporate bottom line.
【译文】这只是在不同时期涉及责任、创作自由和公司底线问题的自我反省。
【析句】这是一个有定语从句的复杂句。主干为It is a self-examination，that后面引导的是限定性定语从句，修饰selfexamination，定语从句的宾语是一个of词组，跟着三个并列的名词短语，用来修饰和限定issues。at various times是插入语，作句子的状语。
【讲词】bottom line意为“底价；底线”。My bottom line is $3000.（我的底价是三千元。）The government's bottom line with regard to the trade issue has not changed.（政府关于贸易争端的底线并没有发生变化。） corporate意为“公司的；社团的；法人的；共同的”。They made a corporate effort to finish the job.（他们通过集体的共同努力完成这项工作。）corporate responsibility（共同责任或法人责任）。
2. In 1992, when Time Warner was under fire for releasing Ice-T's violent rap song Cop Killer, Levin described rap as lawful expression of street culture, which deserves an outlet.
【译文】 1992年时代华纳公司因出品Ice-T乐队狂暴的说唱歌曲《警察杀手》后备受谴责时，莱文说说唱音乐只是街头文化的合法表达方式，它应该有自己的宣泄途径。
【析句】 这是一个主从复合句，从句（when Time Warner was under fire for releasing Ice-T's violent rap song Cop Killer）表示时间；非限制性定语从句which deserves an outlet修饰street culture。
【讲词】 under fire意为“受到攻击；遭到抨击”。The minister came under fire when the accident happened.（在事故发生后，那位部长遭到了抨击。） I was under fire when the board reviewed my proposal.（在董事会讨论我的提案时，我遭到了批评。）
