2. 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。
3. 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。
4. period与定冠词the连用,意思是“现代,当代”。

1. 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）；
2. 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）；

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。
