復雜的定語從句的拆分和理解 例5

例5　To those who are unaware that animal research was needed to produce these treatments, as well as new treatments and vaccines, animal research seems wasteful at best and cruel at worst.

【結構分析】開頭是個介詞短語to those，后面是定語從句，定語從句的主語是who，動詞是are unaware，后面是賓語從句that animal research was needed to produce these treatments, as well as new treatments and vaccines，句子真正的主干是animal research seems wasteful at best and cruel at worst。

【亮點回放】此句話的亮點在于對于那些不了解動物實驗的人進行解釋，這個句型是To those who are unaware that..., sth seems...比如To those who are unaware that English learning is so important, teachers seem to play a crucial role in explaining it。

【核心詞匯】

unaware　不知道

animal research　動物研究

produce these treatments　進行這些治療

vaccines　疫苗

wasteful at best and cruel at worst　說得最好聽是浪費，說得最難聽是殘忍

【參考譯文】對于那些不知道做這些醫(yī)療、研究新的治療方法和疫苗就需要進行動物研究的人來說，動物研究說的最好聽是浪費，說得最難聽是殘忍。
