Learner notes
Memory Tip
联想记忆：broad（宽广）+ cast（抛撒），把声音或画面抛撒到宽广的范围——广播。
Context & Register
语域：neutral 常见场景：新闻与媒体、科技与通信、日常交流 通常用于媒体传播（如广播、电视、网络直播），也可用于正式通知或日常比喻；语气中性，正式和非正式场合都比较常见。
Pronunciation & Spelling
All listed words share the final sound sequence /æst/; -cast words add /k/ before it. Cast, forecast, and podcast are exact spelling-and-sound matches: they end in -cast and are pronounced /kæst/, just like the final syllable of broadcast /ˈbɹɑdkæst/. Last, fast, and past also share the /æst/ ending but use the spelling -ast. Be careful with lookalikes like breakfast /ˈbrɛkfəst/: although it starts with br- and ends with -st, its final syllable is /fəst/ with a schwa, so it does not match.

该词属于 Oxford 核心词汇，值得优先掌握常见搭配和句型。
