【词汇突破】
appropriate 恰当的,合适的
liability 责任(duty, obligation, commitment 的同义替换词)
【主干识别】It isn't clear that+主语从句(it 为形式主语)。
【其他成分】while warnings are often appropriate and necessary and many are required by state or federal regulations 为让步状语从句; the dangers of drug interactions, for example 为插入语; that they actually protect the manufacturers and sellers from liability 为主语从句; if a customer is injured 为条件状语从句。
【微观解析】在 while 引导的让步状语从句中,并列分句可还原为 while warnings are often...and many warnings are required...
【难点揭秘】各种从句交织在一起会导致主干模糊,其中也包括插入语的出现。
【译文赏析】尽管警告常常是适当而且必需的—一比如对于药物相互作用的危险提出警告——许多警告也是按照州或联邦政府规定的要求给出的,然而(我们)并不清楚,当顾客受到伤害时,这些警告其实是在帮助生产者和销售者免责。
