语境与语域Context & Register
语域：mixed 常见场景：craft or pottery shaping、phonetics instruction、numerical estimation、route descriptions round 作动词时语域会随搭配变化：表示“使成圆形/变圆”或“把数字四舍五入”时通常属于中性；表示“绕过、拐过”时多用于叙述性语境，在口语化表达中也较常见。建议先掌握常见搭配，再根据具体场景选择语域。
发音与拼写Pronunciation & Spelling
以上各词与 round 押韵，均含 /aʊnd/。注意：不要仅凭拼写判断，-ound 也可能读其他音，例如 wound 指“伤口”时读 /wuːnd/，不押韵；只有作 wind 的过去式时才读 /waʊnd/，与 round 押韵。
