some times;sometimes;some time；sometime各是什么意思,怎么区分

sometimes 意为“有时”.
如：He sometimes writes to me.他有时给我写信.
sometime意为“某个时候”,可用于将来或过去来.
如：Come to see us sometime.什么时候来看看我们.
I’ll speak to him about it sometime.我什么时候将和他谈谈这事.
注：这样用的 sometime 也可写成 some time (即分开写).
如：

some time 有两个用法：用作副词词组,意为“任何时候”或“某个时候”(= sometime)；用作名词词组,意为“一段时间”(不能写成 sometime).如：
It takes quite some time.它要花相当多时间.
Please phone me some time/sometime next week.下个星期什么时候给我打个电话吧.

some times 意为“几次”
