大写或小写都有可能，其原则是：如果省略号后面的词在不省略的情况是大写，则省略后它仍为大写；如果省略号后面的词在不省略的情况是小写，则省略后它仍为小写。如：

(1) Have you got a whatchamacallit? You know... a screwdriver? 你有一把……叫什么来着的？你知道的…螺丝刀？  

(2) There are Indian, Chinese, Mexican, Thai restaurants... and then some! 有印度、中国、墨西哥、泰国餐馆……，而且还有很多其他国家的餐馆!

(3) The senator called the new highways proposal “...a fraud and a boondoggle that the taxpayer should not tolerate”. 参议员称新的道路建设计划是“……毫无意义的骗钱工程，纳税人不应该容忍”。

(4) Once upon a time there were three little pigs. One day... Then... Soon after that... After dark.. 从前有3只小猪。有一天……后来……那以后不久……天黑以后，……

(5) Firstly, we need to increase profits. Secondly,... Thirdly,... And lastly, we need to cut down administrative expenses. 首先，我们需要增加利润。第二，……第三，……最后，我们需要削减行政开支。 

(6) Smith passes to Devaney, Devaney to Bames, Barnes to Lueas—and Harris intercepts... Harris to Simms, nice ball—and Simms shoots! 史密斯把球传给德瓦尼，德瓦尼传给巴恩斯，巴恩斯又给卢卡斯——哈里斯把球断下来……哈里斯传给西姆斯。好球——西姆斯射门!

▲如果省略号后面的是一个句子，且省略号所省略的成分和结构不是很清楚，则省略号后面的句子用大写或小写均可以。如：

(1) Let me see... where did I put my wallet? 让我想想…我把钱包放在哪儿了呢？

(2) Let me see... Where did I put my wallet? 让我想想…我把钱包放在哪儿了呢？
