難易度分析
3 / 5
本題考查連綴動詞後的補語結構以及詞性修飾的搭配準則。由於選項中包含了相同詞根的不同詞性（名詞、形容詞、副詞），考生必須精確區分各詞類在句中的文法功能，才能在相似的選項中做出正確判斷。
正確答案：③mutually beneficial
③ mutually beneficial:mutually（副詞）正確修飾 beneficial（形容詞），符合 proved + 形容詞 的句型結構，表示「證明是互惠有益的」。
錯誤選項解析
- ① mutual benefit:mutual benefit 為名詞片語，而 proved 在此處作連綴動詞使用，後方應接形容詞作為主詞補語，不可接名詞片語。
- ② mutual beneficial:mutual 是形容詞，不可直接修飾另一個形容詞 beneficial。修飾形容詞必須使用副詞，此為常見的文法混淆點。
- ④ mutually beneficially:mutually beneficially 為兩個副詞疊用，但 proved 作為連綴動詞後方需要形容詞作補語，而非副詞。
Learning Tip
"本題核心考點為連綴動詞 proved 的補語結構及副詞修飾形容詞的文法規則。貿易函電中常見 prove mutually beneficial（證明雙方互惠）的固定搭配，需牢記 mutual（形容詞）→ mutually（副詞） 的詞性轉換。常考陷阱在於混淆 benefit（名詞）、beneficial（形容詞） 與 beneficially（副詞） 的用法。"
