contaminate 是一个动词,主要含义是使某物变得不纯净、不洁净或有害,通常指通过引入有害或不受欢迎的物质。其核心在于污染、玷污或损害原本纯净或安全的状态。
以下是详细解释:
核心含义:引入杂质或污染物
工业废水contaminated the river, making the water unsafe for drinking. (工业废水污染了河流,使水无法安全饮用。)

:用某物污染某物。 (e.g., The lake wascontaminated with sewage. 湖水被污水污染了。)be/become/get contaminated
:被污染。 (e.g., The drinking waterbecame contaminated. 饮用水被污染了。)与近义词的细微区别:
contaminate
在“污染”义上常互换,但 pollute
更常指大规模的环境污染(如空气污染、河流污染),有时带有“道德败坏”的强烈贬义。Contaminate
更侧重于纯净物被有害杂质侵入的结果,常用于具体物质(如食物、水源、样本)或生物性污染(如细菌感染)。Contaminate
程度可轻可重。Contaminate
指被病原体污染(如伤口、表面),但不一定导致感染。 例句:
Contaminate
的核心是通过引入有害或不需要的物质,破坏纯净、安全或良好的状态,既可指物理上的污染(如水、食物),也可指抽象意义上的玷污(如声誉)。它在描述具体物质被有害杂质(尤其是生物或化学污染物)侵入时最为常用。
