94.Although she had signed a pledge of abstinence while being an adolescent, Frances Willard was 35 years old before she chose to become a temperance activist. (B) while in adolescence (D) as being in adolescence (E) as an adolescent
我只提供一种看法,作为参考。 我认为,while作为连词引导句子,当然你可以认为省略的she was,但是,这无法改变一个事实,那就是:这还是一个句子(连词+介词结构),而as结构则是一个介词短语,比句子要简洁,所以E更好。而且,我认为,while的省略结构其实不够严谨,会引起歧义,比如while her brother was in adolescence可以作为一种解释,那么就改变了句义,所以,这种表达应该不是标准书面语表达,而仅仅是一种口语表达。 再次申明,我只是提供一种参考,尤其是关于书面语和口语表达的那种看法,因为我不能完全肯定。
