影子（shadow）总跟在人身后，故动词意为“跟踪、尾随”；影子遮光，又引申出“遮蔽、使变暗”。记住“影子”这两个动作即可。
语境与语域Context & Register
语域：mixed 常见场景：侦探/调查、文学/书面描写、职场见习 shadow作动词时，语体会因义项而不同：表示“暗中跟踪/监视”时多为中性，侦探、新闻或日常对话中都常用；表示“遮蔽、使变暗”时偏书面或文学；表示“跟随见习”时则较正式，常见于职场或教育语境。使用时应根据具体义项判断，不宜一概而论。
语法说明Grammar Note
及物动词，通常后接宾语。
发音与拼写Pronunciation & Spelling
这些词都不与 shadow（/ˈʃædoʊ/）完全押韵：它们虽然拼写都以 -ow 结尾，但重读元音不同。window、follow、yellow、shallow、meadow 的 -ow 都读 /oʊ/，与 shadow 的末尾音一致；而 now 的 -ow 读 /aʊ/，是典型的拼写误导词。不要因为拼写把 shadow 读成 /ʃaʊ/。
