【问】 Excessive stress sometime causes the dice of a spinal vertebra to press on a nerve.(TOEFL，82.1)
 请就此托福题讲一讲sometime，sometimes与some time的区别。
 【答】 sometimes是一个表示时间频率的副词，意为“有时候”。其语法特点相当于always，of-ten。sometime可与过去时或将来时连用，表示“(在过去)某个时候”或“(在将来)某个时候”，指的是时间点。例如：
 1. I saw him sometime in May. (OSD)
 我在五月的某个时候曾见到过他。
 2. Our house was built sometime around 1905.(LDCE)
 我们的房子是在1905年某个时候建成的。
 3. I’ll buy a fur hat sometime. (CGEL)
 在将来某个时候我要买一顶毛皮帽子。
 4. Shall we start sometime later next week，say，Friday?
 我们是不是下周晚些时候动身，比如说周五怎么样?
 some time是个名词短语，是指“一些时间”、“一些时候”、“相当长的时间”，指的是时间段(a period of time)。some time有时也表示“某天”、“某个时候”：
 1. Let’s have dinner together some time next week. (PEU)
 让我们下周找个时间一起吃饭吧。
 2. I’ll be away for some time.
 我要离开一些时间。
 3. After some time，the bus stopped. (New Concept English，Book 2，L. 50)
 过了一些时候，公共汽车停了。

 5. I continued driving and after some time，the examiner tapped loudly. (New ConceptEnglish，Book 2，L.69)
 我继续开车，过了一些时候，主考官重重地敲车窗。
