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。

n.(名词)正常上课的日子有六节课。

误 There are six lesson period in a normal school day.

正 There are six lesson periods in a normal school day.

析 period作“学时、课时”解时有复数形式。

在那些动乱年代里,我们在农场呆了很久。

误 During those years of turmoil, we stayed on a farm for a long period of time.

正 During those years of turmoil, we stayed on a farm for a long time.

析 误句中的period of是多余的,应删去。
