单词分析：这些连词均可表示“当……时”引出时间从句。
when所引导的从句，其谓语动词既可是持续动词，也可是短暂动词；谓语动词动作发生的时间可以与主句谓语动词的动作是同时，或之前、之后。
while句中的谓语动词应为持续动词，不用短暂动词，谓语动作发生的时间通常与主句谓语动词动作发生时间是同时。
as侧重指从句与主句的动作同时进行，谓语动词可以是持续性的，可以是短暂性动词。

英语词源

when

when: [OE] When was formed from the ancient interrogative base *qwo- (source also of English what, who, etc) and a nasal suffix which also appears in then. From the same ancestor, but with an additional dental suffix, came Latin quando ‘when’, source of English quandary.
=> quandary

when (adv.)

Old English hwænne, hwenne, hwonne, from Proto-Germanic *hwan- (cognates: Old Saxon hwan, Old Frisian hwenne, Middle Dutch wan, Old High German hwanne, German wann "when," wenn "if, whenever"), from pronominal stem *hwa-, from PIE interrogative base *kwo- (see who). Equivalent to Latin quom, cum. As a conjunction in late Old English. Say when "tell me when to stop pouring you this drink" is from 1889.
