語境談話時忽然想到另一件事為了轉變話題常用By the way中文常譯為「順便一提」．其實這應該譯為「對了」．但By the way是句子間的連接詞組，沒辦法用在單句．

語境 『你回家的時候可以順便幫我買包煙嗎?』中的「順便」其實是含有「便捷」的意思．用英文說，就是conveniently, in it, without extra effort, incidentally．事實上的詞組用詞可以用in passing, at your convenience, take this opportunity甚至于不需要任

何詞組，而用從整個句子的語氣上得來〔見下面的例子〕！

例 ：I mention this point now in passing and shall refer to it again. 這一點目前先順便提一下，將來還會再提到．

例：I take this opportunity to report to you about a matter.順便向各位報告一件事．

例：On your way home, could you please get a pack of cigarettes for me, at your convenience? 『你回家的時候可以順便幫我買包煙嗎?』．

例：〔甚至不需要at your convenience，從語氣上就有「順便」的氛圍〕．I often look in at the bookstore on my way home from work.我下班回家，常到書店看看．

例：When you go to the library, please return this book for me.你去圖書館管的時候，把我這本書還了吧．〔本句中Whenfor me就有「順便」的氛圍〕．

例：Please take this study material with you to the class.你把這份講義拿到班上去．〔本句中Whenwith you就有「順便」的氛圍〕．

例：When you go shopping, please buy me a pair of small scissors^{2.你去購物的時候，替我買一把小剪刀．〔本句中只用When而不需要其它任何詞組，從語氣上來看，就有「順便」的氛圍〕．}

例：When my cousin came to Taipei on business, he stayed with me for two nights. 我表弟來臺北出差時，來我家住了兩晚．〔本句中只用When而不需要其它任何詞組，從語氣上來看，就有「順便」的氛圍〕．

例：When you go to Kingstone Bookstore, please ask when this month's issue^{3 of World Movie will be in.你去金石堂書店的時候，請問一下新的一期「世界電影」雜志什么時間到．}
