经典文学不仅寓意深刻，而且其魅力历久弥新。(Not only，fade)

Not only do classic literary works have profound meanings, but also their charm never fades over time.

考查固定句型、倒装用法、名词短语和动词短语。根据句意以及句子的提示词可知，该句应为Not only ... but also ... 的固定句型，句子陈述一般性事实，时态为一般现在时，表示 “经典文学” 应为名词短语classic literary works；表示 “寓意深刻” 应为动词短语have profound meanings，not only位于句首，句子需要部分倒装，将助动词do提前；表示 “他们的魅力” 为名词短语their charm；表示 “历久弥新” 应为动词短语never fade over time，主语为单数，谓语动词fade用单数形式。故翻译为：“Not only do classic literary works have profound meanings, but also their charm never fades over time.”。
