记忆技巧Memory Tip
additive 开头是 add(加),记住“添加上去的”就是 additive;食品添加剂 add 进食物里,也读作 /ˈædətɪv/。
语境与语域Context & Register
语域:formal 常见场景:mathematics、chemistry、engineering additive 作形容词时通常用于正式或学术场合,多出现在数学、化学、工程等专业术语搭配中,表示“添加的、附加的、加成的”;在日常口语中较少使用,说 additional 或 added 可能更自然。
发音与拼写Pronunciation & Spelling
这些词与 additive 拼写相近,都含有 -itive/-ative 后缀,但都不能与 additive /ˈædətɪv/ 完全押韵:additive 的重读部分为 /æd/,而 positive、negative、relative、sensitive、competitive 的重读元音分别为 /ɒ/、/ɛ/、/ɛ/、/ɛ/、/ɛ/,definitive 的重读在第二音节 /ˈfɪn/。它们共享的是不重读的 /ətɪv/ 或 /ɪtɪv/ 结尾,而不是完全相同的韵。注意 negative 和 relative 拼写是 -ative,读音也是 /ətɪv/。
