average（adj. 平均的; 普通的）词源演变：来自 古法语 avarie（12世纪），指“船只的损坏或损失”。进一步源自 阿拉伯语 ʿawārīya（عَوَارِيَّة），意为“损坏的货物”（中世纪地中海贸易术语）。在商业保险中，avarie 指“共同海损”（损失由船主和货主共同分担），由此引申出“按比例分摊”的概念。16世纪英语中，average 开始表示“算术平均数”，强调“均衡分配”的数学概念。造句：1. His IQ is abve average.2. I was just an average srt f student.
Kilmetre（千米/公里）kilmetre = kil-(千) + metre（米）类似构词法的单位centimetre（厘米，centi- = 百分之一）,缩写“cm”kilgram（千克），缩写“kg” 拼写差异（英式 vs. 美式）英式英语：kilmetre美式英语：kilmeter
Spare（空闲的）1. 词源发展Spare 来自古英语 "spær"2. 语义演变古英语时期（5-11世纪）："Spær" 形容“数量稀少”或“使用节制”，如 spær land（闲置的土地）。中古英语时期（12-15世纪）：发展出动词含义 "sparen"（节省、保留），如 t spare mney（省钱）。现代英语：形容词指“备用的”（a spare tire）或“空闲的”（spare time）。3. 词义关联逻辑若资源（时间、物品）被节省（spared），则自然成为闲置的（spare）状态。例：Save/spare mney → 结果是有 spare cash（闲钱）。例句：D yu have any spare pens? I paint in my spare time.
