contaminate 是一個動詞,主要含義是使某物變得不純淨、不潔淨或有害,通常指通過引入有害或不受歡迎的物質。其核心在于污染、玷污或損害原本純淨或安全的狀态。
以下是詳細解釋:
核心含義:引入雜質或污染物

在“污染”義上常互換,但 pollute
更常指大規模的環境污染(如空氣污染、河流污染),有時帶有“道德敗壞”的強烈貶義。Contaminate
更側重于純淨物被有害雜質侵入的結果,常用于具體物質(如食物、水源、樣本)或生物性污染(如細菌感染)。Contaminate
程度可輕可重。Contaminate
指被病原體污染(如傷口、表面),但不一定導緻感染。 例句:
Contaminate
的核心是通過引入有害或不需要的物質,破壞純淨、安全或良好的狀态,既可指物理上的污染(如水、食物),也可指抽象意義上的玷污(如聲譽)。它在描述具體物質被有害雜質(尤其是生物或化學污染物)侵入時最為常用。
