n.名词
period, age, generation这三个词的共同意思是“时期”。其区别是： period是这组词中最一般的常用术语,用于任何时限,时间可长可短; age意为“时代,寿命”,常用来表示以一个中心人物或显著特征而闻名的时期; generation意为“代、世代”,用于上辈出世与下辈出世之间的时段,对人类来说这段时间有时可算作20年或25年,也可用于下辈本身。例如: The period in which people learnt to make tools of iron is called the Iron Age.人类学会用铁制造工具的时代,我们称为“铁器时代”。 My generation behaves differently from my father's and grandfather's.我这一代人和我父辈及祖辈表现不同。age，epoch，era，period，times这些名词均含“时期、时代”之意。 age常指具有显著特征或以某杰出人物命名的历史时代或时期。 epoch正式用词，侧重指以某重大事件或巨大变化为起点的新的历史时期。 era书面语用词，指历史上的纪元、年代，可与epoch和age互换，侧重时期的延续性和整个历程。 period最普通用词，概念广泛，时间长短不限，既可指任何一个历史时期，又可指个人或自然界的一个发展阶段。 times侧重某一特定时期。 英语的“句号”叫period或 fullstop.Period来逢希腊语的periodus，意思是“周期”，“循环”，period至今仍保留着这层意思。到了16世纪末，这个词则用来指任何动作的完成时刻，继而指一个句子的完结，或一句话后的停顿时间，最后才变成一个圆点，标志一个句子的结束。

n.名词
period的基本意思是“一段时间”,是可数名词,复数形式为periods。 period可作“时期,时代”解,指某个历史阶段或时期; 也可作“课时,学时”解; 还可作“月经期”解。 在美式英语中period的意思是“句号,句点”,相当于英式英语的a full stop。 period与定冠词the连用,意思是“现代,当代”。 period表示一段时间时，一般不指一点时间。如果从全部过程的角度来看，每一个period也可算是一“点”，常与介词at连用。 例：at any period of the year在这一年的任何一个时段； 表示朝代时，用dynasty或period，如Qing Dynasty/Period清朝。表示某个皇帝的朝代时，用reign或period来表示，如the Qian Long Reign/Period乾隆朝； 英美人还常把period解释为“句号”，不过在美国更普遍。
