some time,sometime,some times和 sometimes是常用的几个词,它们形似而含义不同.请记住下面口诀：
分开是“一段”,相连为“某时”.
分开s是“倍、次”,相连s是“有时”.
读读下面四句话,便会运用这四个词.
例如：
（1）I’ll stay here for some time．我将在这儿呆一段时间.
（2）Kate will be back sometime in February．凯特将在2月某个时候回来.
（3）Our school is some times larger than theirs．我们学校比他们学校大几倍.
（4）Joan goes to school on foot,but sometimes by bike．琼步行上学,但有时也骑自行车去
