OALD4: book that lists and explains the words of a language, or gives translations of them into one or more other languages, and is usu arranged in alphabetical order
OALD7/8/9: a book that gives a list of the words of a language in alphabetical order and explains what they mean, or gives a word for them in a foreign language
看出区别了吧, OALD4 说的 dictionary is usually arraged in alphabetical order ,OALD7/8/9 都没有说 usually 。词典,可不都是按字母顺序排列的噢,这条释义,OALD4 更精确。
老词典更实诚,看封底,说的是 57100 words and phrases, over 4000 NEW to this edition,再看看第 8 版,“184500 单词、短语和释义”,也不能说人家吹牛,词头也就五六万,释义数可能有十几万。。。。。
