2.句子成分分析:本句是一个复合句。句子的主干是:it did so。it是句子的主语,did是谓语动词,so是宾语。while引导伴随状语while holding its nose at the ethics of his conduct,主干为(it was)holding its nose...his conduct。which引导宾语从句,其先行词为conduct,举例说明违背了道德标准的具体行为which included accepting gifts such as a Rolex watch and a Ferrari automobile from a company seeking access to government。seeking access to government为a company的后置定语。while引导状语从句时,如果主句和从句的主语一致,且从句谓语又含有be,则从句中有时可省略主语和be,while后可以直接跟现在分词、过去分词、名词、形容词或介词短语。
