词义讲解

词源解说

adj.(形容词)

alert作形容词的基本意思是“警惕的,警觉的,注意的”,指特别留神以应付可能发生的事,尤指危险的事; 引申也可指“机灵的,敏捷的”,指思维敏捷,理解快,可用来形容人,也可用来形容物。

alert常用作表语,后接介词in或to,偶尔也可用作定语。

v.(动词)

alert的基本意思是指让某人对可能发生的危险或潜在的危险保持警觉或准备好迎击敌人,可译作“(向)…发出警告,使处于戒备状态”。

alert是及物动词,提醒、警觉或戒备的内容常由介词to引出,提醒作为准备的内容则由介词for引出。

alert也接双宾语,其直接宾语多为that引导的从句。alert还可接以动词不定式充当补足语的复合宾语。

n.(名词)

on alert,on the alert

这两个短语形似义近，其区别是：

on alert是针对危险情况的，意思是“防备着”；on the alert是针对事态发展的，意思是“随时准备着”。

☆ 17世纪进入英语，直接源自法语的alerte，意为vigilant；*初源自意大语的allerta，意为到高处。
