Context & Register
语域：formal 常见场景：biology/zoology、seafood industry、academic writing bivalve 是较正式的专业用语，多用于生物学、海洋学或渔业等书面/专业语境；日常口语中更常直接说 clam（蛤蜊）、mussel（贻贝）、oyster（牡蛎）等具体贝类名称。
Pronunciation & Spelling
bivalve 读作 /ˈbaɪvælv/，重音在第一音节。词尾 -valve 在 valve、univalve 中相同，但这两个词的重音元音不同，所以不和 bivalve 押韵。前缀 bi- 在 bicycle、biology 中同样读 /baɪ/。alive、arrive 以 /aɪv/ 结尾，与 bivalve 开头的 /baɪ/ 有相似之处，但结尾不是 /vælv/。注意 valve 中的 a 读 /æ/，不要读成 /eɪ/。
