把 hard(硬)和名词后缀 -ness 连在一起,就是“硬度”;想象钻石在莫氏硬度表上划玻璃。
语域:formal 常见场景:材料科学、矿物学、物理测试、工程技术 表示物理性质“硬度”时,通常用于材料科学、矿物学等正式或技术性语境;日常口语中较少单独使用,比较常见于硬度测试、摩氏硬度等书面表达。
这些词都以 -ness 结尾,后缀发音为 /nəs/,但都不与 hardness /ˈhɑrdnəs/ 完全押韵,因为 hardness 的重读元音 /ɑr/ 后还有 /d/ 音,形成 /-rd nəs/。注意 harness /ˈhɑrnəs/ 拼写与 hardness 很像,但缺少 /d/ 音,读音不同。darkness /ˈdɑrknəs/ 和 sharpness /ˈʃɑrpnəs/ 虽然也有 /ɑr/,但后面分别接 /k/ 和 /p/,不押韵;witness /ˈwɪtnəs/ 和 kindness /ˈkaɪndnəs/ 的元音也各不相同。
