some time，sometime，sometimes

Some time作为名词片语，是指一定的时限而言，表示相当长的一段时间（a long time）；作副词片语时，意为“随便何时”。例：

我已好久没有看见梁先生，我十分想念他。

Sometime作为副词，意思是“在某一时候”、“日后”、“昔时”，指不定的时间而言，既可指将来亦可指过去的不确定时间（any time in

the future or in the past）。例：

I will tell you sometime or other．

我将来会告诉你的。

He gave us a detailed report sometime ago．

他曾给我们一个详细的报告。

Sometime亦可用作形容词，放在名词之前作定语。例如：

He was a sometime university professor．

他曾经是大学的教授。

从例句可见，这里的sometime相当于onetime或former之意。

Sometimes的意思是“有时”、“不时”（at times；now and then）。例：

The weather is cold and changeable．Now it rains，now it snows，sometimes it hails．

气候冷而多变，时而下雨，时而下雪，有时还下冰雹。
