① The accident happened sometime last month
② Let us discuss the matter sometime next week.
Sometimes是個頻率副詞，意思和 “occasionally”，或“from time to time”甚接近，就是“有時候”或“偶爾”之意。 “Sometimes”和“sometime”不但意思不同， 所處的位置也不壹樣。
“Sometimes”可以在下列三處出現：
⒈句首，如：Sometimes, I didn't feel like working.
⒉接系動詞“be”之後，如：The new manager was sometimes very hot-tempered.
⒊動詞前，如：They sometimes stayed up until 2 o'clock.
從這三個例子看，“sometime”和“sometimes”不但意思不同 ， 所處的位置也大相徑庭。
就用途來說， “sometime”的用途廣些。除了表示“在某時期 ”這意思之外，它也含有“任何時候”的意義，如：* Come over and see me sometime. 這裏的“sometime”，可以用“anytime”代替，即： Come over and see me anytime.
此外，“sometime”可以當形容詞用，意思是“以前的”，如：
* Dr Chen, a sometime lecturer of chemistry, is now a big company director.
這裏的“sometime”不妨以另外壹個形容詞“former”或前綴“ ex-”來取代：
*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“在某時期”；“some time” 是“壹段時間”，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.
由於 sometimes, sometime和 some time 各有不同的意思，在同句裏出現可以和平***處、相安無事：
* Sometimes, I spent some time reading a sometime English lecturer's novel written sometime in 1996.
