There is nothing (like the suggestion) (of a cancer risk) [to scare 1a parent], [especially one of the over-educated, eco-conscious type]. [So] you can imagine the reaction [when a recent USA Today investigation 2 (of air quality around the nation’s schools) singled out 3 those [in the smugly green village of Berkeley, Calif.],] [as being among the worst in the country]. The city’s public high school, as well as a number of daycare centers, preschools, elementary 4 and middle schools, fell in 5 the lowest 10%. Industrial 6 pollution [in our town] had [supposedly] turned students [into living science experiments] [breathing in a laboratory’s 7 worth of heavy metals] {like manganese 8, chromium 9 and nickel 10} [each day]. This [in a city] (that requires school cafeterias 11 to serve organic meals.) Great, I thought, organic 12 lunch, toxic 13 campus. 14
没有什么事情能像癌症风险一样让家长感到恐慌的了，尤其是对一些受到过多教育、对生态环境敏感的人来说。所以当《今日美国》在近期公布的一份全国范围内的学校周边空气质量调查中，把加州伯克利的绿色环保小镇列为全国最差时，你可以想象到那些自鸣得意的人的反应了。该市的公立高中以及为数众多的日间看护中心、学前教育机构、小学和中学都排在最差的10%之列。我们这座城市的工业污染大概把学生置于活体科学实验之中，学生们每天吸入锰、镉和镍等重金属，像在实验室一样。这发生在一个要求学校的餐厅提供有机食品的城市里。多棒啊，我想，有机午餐，有毒校园。

14. 后面两个词语表并列对比，并非完整的句子。而句首的great很明显是表讽刺揶揄，俗称说反话。
[Since December], [when the report came out,] the mayor, neighborhood activists and various parent-teacher associations 1 have engaged in a fierce 2 battle [over its validity 3]: [over the guilt of the steel-casting factory on the western edge of town, over union jobs versus 4children’s health and over what, ^if anything^, ought to be done]. [With all sides presenting their own experts] [armed with conflicting scientific studies], whom should parents believe? Is there [truly] a threat (here), we asked one another [as we dropped off 5 our kids,] and [if so,] how great is it? And how does it compare with the other, [seemingly 6 perpetual 7 health scares (we confront 8],) [like panic over lead in synthetic athletic fields]? [Rather than just another weird episode 9 in the town (that brought you protesting environmentalists],) this latest drama is a trial 10 [for how today’s parents perceive 11 risk, how we try to keep our kids safe] – ^whether it’s possible to keep them safe^ – [in what feels like an increasingly threatening world]. It raises the question (of what, ^in our time^, “safe” could [even] mean) 12.
自12月份报告出炉，市长、社区活跃分子和各种家长老师联合会都参与到一场关于报告的可信度的激烈斗争中：争论市西端炼钢厂的罪恶、争论公会工作和孩子的健康之间的矛盾，争论任何应该做的事。当各方都亮出握有彼此矛盾的科学依据的专家时，父母究竟应该相信谁？当我们开车到学校把孩子放下时，我们问彼此，这儿是不是真的存在危险？如果真有危险的话，有多大？和其他的、我们似乎要长期面对的健康担忧相比又如何？比如对合成材料制成的运动场中含铅的恐慌。最近的这个事件不仅仅是一件又带来环境主义者抗议的奇特事件，它验证了，在一个好像越来越让人感到威胁的世界里，家长如何看待危险，我们如何尽力维护孩子的健康——无论能否保证孩子们的健康。它带来了一个问题：在我们这个时代“安全”究竟意味着什么。

12. of所接部分为定语，修饰question，但值得留意的是，该定语中包含了一个句子，也就一并分析了出来。
“There’s no way (around the uncertainty),” says Kimberly Thompson, {president of Kid Risk}, {a nonprofit group} (that studies children’s health.) “That means your choices can matter, but it [also] means you aren’t going to know if they do.” A 2004 report (in the journal Pediatrics) explained that (nervous) parents have [more] to fear [from fire, car accidents and drowning] [than from toxic chemical exposure 1]. [To which] I say: ^Well^, obviously. But such concrete 2hazards are beside the point 3. It’s the dangers parents can’t – ^and may never^ – quantify that occur [all of sudden 4]. That’s why I’ve rid 5 my cupboard (of microwave food) (packed in bags) [coated with 6 a potential cancer-causing substance 7], but [although I’ve lived blocks [from a major fault line] [for more than 12 years],] I [still] haven’t bolted 8 our bookcases [to the living room wall].
“没有办法解决不确定的问题，”儿童风险主席Kimberly Thompson说，“这意味着，你的选择可能会起影响作用，但这也意味着你无法了解你的选择是否在起作用。” 2004年发表在学术期刊《儿科学》杂志上的一篇报告解释说，紧张的家长更应该担心的是火灾、车祸和溺水，而不是有毒化学物质。对此我认为：当然，是这样。但是这些具体的危险并非关键所在。关键是那些家长不能——可能永远也不能——确定会突然发生的危险。这正是为什么尽管12年来我一直生活在位于地质断层的街区里，我仍然没有把书柜固定在卧室墙上，却要把橱柜里用涂有潜在致癌物的袋子包装着的微波炉食品扔掉。
注：1. exposure n. 暴露，揭露；(to)受到。例：

【同】all at once。例：

她们吻你时，世界瞬间变得美妙。
本句it is that看似是强调句，但实际上不是，强调句型可以将it is that剔除而不影响句子结构与意思，而在这里，去掉之后句子显得不通顺，因为that在句子中做主语，而不是宾语从句的标识。
