原句（分詞結構）

The scientist, having spent several decades in marine biology, published a groundbreaking paper on deep-sea ecosystems.

還原方式一：使用時間副詞子句（最清楚、最正式）

After the scientist had spent several decades in marine biology, he/she published a groundbreaking paper on deep-sea ecosystems.

  • 「having spent」＝ after + had spent

  • 明確表達「先後順序」

  • 非常適合學術寫作與文法理解

還原方式二：使用關係子句（較中性）

The scientist, who had spent several decades in marine biology, published a groundbreaking paper on deep-sea ecosystems.

  • 將分詞片語改為 非限定關係子句

  • 語意正確，但「先後時間關係」不如方式一明確

  • GRE 可接受，但精確度略低
