托福長難句分析：動物繁殖后代

　　An animal that can remember the significance of that large, nasty-looking thing with the big teeth and sharp claws will survive longer and produce more offspring.

　　譯文：一種動物只有記住了長相丑惡(具有巨大牙齒和鋒利爪子)且身體龐大的重要性，才能生存長久并繁殖更多的后代。

　　句型分析：本句是復合句，句子的主干為An animal will survive longer and produce more offspring。

　　定語從句：主語animal后接關系代詞that引導的定語從句，關系代詞代替animal在從句中作主語。在從句里，謂語動詞 remember的賓語是the significance，它的后置定語為that large, nasty-looking thing with the big teeth and sharp claws;介詞短語with the big teeth and sharp claws補充說明thing的特點。
