NOTES
The adolescent grows up to become the adult.The wordsadolescent  andadult  that refer to these two stages in the human life cycle ultimately come from forms of the same Latin word,adol¶scere,  meaning “to grow up.” The present participle ofadol¶scere, adol¶sc¶ns,  from whichadolescent  derives, means “growing up,” while the past participleadultus,  the source ofadult,  means “grown up.” Appropriately enough,adolescent,  first recorded in English in a work written perhaps in 1440, seems to have come into the language beforeadult,  first recorded in a work published in 1531.
    青少年成长为成年人。adolescent 及adult 这两个词都表示人类生命循环中的两个阶段，并且始终都来自于同一个拉丁词adolescere 的不同形式，意为“成长”。 现在分词形式的adolescere--adolescens 产生出adolesent ，表示“正在成长的”， 而其过去分词adultus 则为adult 的语源，意为“已经长大的”。 很恰当地是，adolescent 约于1440年首次用于英语作品中， 似乎比首次于1531年刊登在一作品中的adult 一词要早出现在英语语言中
