somtime,some time,sometimes,some times的用法,区别麻烦讲解下它们各自是什么意思,用在什么时态的句子中,有什么区别.麻烦顺便举几个例句,方便区别.

sometime为副词，意思为将来某个时候；过去某个时候。例句（1）We'll take our holiday sometime in August, I think.可以用过去时，或者将来时
我想我们大概会在八月放假。
（2）Our house was built sometime around 1973.我们的房子建于1973年左右。
some time 为词组，意思为在未来的某时,经过若干时间。例句：I will need some time to think over your offer.我需要一些时间来考虑你的提议。这个没有特别限制时态，你可以根据语境来判断。
sometimes为副词，意思为有时, 间或，不时。例句：I think of him sometimes.一般用现在时。
some times词组，意思为几次，好几次，数次，若干次。例句：Jack's serve was very good and some times it was confusing to her opponent. 杰克的球发的很好，多次将对手迷惑住了。可以用过去式。

Sometime是个时间副词，意思是“在某时期”。这个字通常 和“日期”或“时间”连用，出现在句子后半部， 用来固定本来不肯定的时间或日期。例如：
① The accident happened sometime last month
② Let us discuss the matter sometime next week.
Sometimes是个频率副词，意思和 “occasionally”，或“from time to time”甚接近，就是“有时候”或“偶尔”之意。 “Sometimes”和“sometime”不但意思不同， 所处的位置也不一样。
“Sometimes”可以在下列三处出现：
⒈句首，如：Sometimes, I didn't feel like working.
⒉接系动词“be”之后，如：The new manager was sometimes very hot-tempered.
⒊动词前，如：They sometimes stayed up until 2 o'clock.
从这三个例子看，“sometime”和“sometimes”不但意思不同 ， 所处的位置也大相径庭。
就用途来说， “sometime”的用途广些。除了表示“在某时期 ”这意思之外，它也含有“任何时候”的意义，如：* Come over and see me sometime. 这里的“sometime”，可以用“anytime”代替，即： Come over and see me anytime.
此外，“sometime”可以当形容词用，意思是“以前的”，如：
* Dr Chen, a sometime lecturer of chemistry, is now a big company director.
这里的“sometime”不妨以另外一个形容词“former”或前缀“ ex-”来取代：
*Dr Chen, a former lecturer of chemistry, is now a big company director.
* Dr Chen, an ex-lecturer of chemistry, is now a big company director.
**另外，“sometime”和“some time"的意思不同。“Sometime”是“在某时期”；“some time” 是“一段时间”，如：
*All of us have studied English for some time.
* Betty has been grumbling for some time.
* Please give me some time to think over your proposal.
由于 sometimes, sometime和 some time 各有不同的意思，在同句里出现可以和平共处、相安无事：
* Sometimes, I spent some time reading a sometime English lecturer's novel written sometime in 1996.
