Memory Tip
联想：carapace 前半像 carry（背负），后半是 pace（步伐）；乌龟背着壳慢步走，背上的甲壳就是 carapace。
Context & Register
语域：formal 常见场景：zoology、biology、literary writing 通常用于生物学或动物学等专业语境，指龟、蟹等动物的坚硬甲壳；也可在文学或比喻性写作中指起保护作用的事物或屏障。总体上属于书面正式用词，日常口语中较少使用。
Grammar Note
可数名词，复数形式为carapaces
Pronunciation & Spelling
face、pace、place、space、brace、trace 都以 -ace 结尾，读作 /eɪs/，与 carapace 的词尾 /peɪs/ 发音一致；但 carapace 重音在首音节，所以这些单音节词并不与之严格押韵。注意 palace /ˈpælɪs/、surface /ˈsɜːrfɪs/ 等同以 -ace 结尾的词读作 /ɪs/ 或 /əs/，是形似而音不同的常见陷阱。
