sometimes，sometime，some times和some time这四个词相似度很高，极易混淆。通常词性决定用法，下面我通过词性和具体实例来区分它们。
He is sometimes late for school.
Tom sometimes plays soccer in the park.
Sometimes Tom plays soccer in the park.
二、sometime是个时间副词。我们可以把它和不定代词someone联系起来记忆，someone意为“某个人”，那么sometime就是“某时”的意思，多用于将来时。例如:We will plant some trees here sometime.
Bob wants to visit Paris sometime next summer.
三、time是名词，如果它作为可数名词，即“次数、倍数”。some times当中的time加了s，说明此处它就是可数名词，那么some times就是“几次”的意思，表示动作频率。例如:She took my phone by mistake some times.
Grace has been to England some times.
四、time还可以作为不可数名词，即“时间”。some time当中的time没有加s，说明此处它就是不可数名词，那么some time就是 “一段时间”的意思，表示动作的持续时间。例如:The heavy snow has lasted for some time.
Tony stayed in the train station for some time.
在区分单词用法时，我们首先要从词性入手，看它属于哪个词类，然后再到具体的例句中分析它的作用，一切就会变得简单起来。
最后，我想告诉大家，我对Baby喜欢到没有抵抗之免疫力，所以，别劝我以后发文不用她的美图啦！
