例199 The brain finds it best to keep smell receptors available for unfamiliar and emergency signals such as the smell of smoke, which might indicate the danger of fire.
【結構分析】這句話是形式賓語it,真正的賓語是不定式to,主干是The brain finds it best to keep smell receptors available,后面加上介詞短語for unfamiliar and emergency signals,后面再加上介詞短語such as the smell of smoke,后面加上定語從句which might indicate the danger of fire。
【亮點回放】此句話的亮點在于形式賓語加上定語從句的超級組合,很有氣勢。
【核心詞匯】
the brain 大腦
smell receptors 味覺接收器
unfamiliar and emergency signals 不熟悉的緊急信號
danger of fire 火災的風險
【參考譯文】大腦發(fā)現(xiàn)最好讓味覺接受器可以用來識別陌生的緊急信號,比如煙的味道,這種味道意味著火災的風險。
