每日一詞：彈幕

“彈幕”，原指向特定方向持續(xù)發(fā)射大量火炮(the continuous firing of a large number of guns in a particular direction，barrage)，現在用來比喻“觀眾的實時評論像子彈一樣在屏幕上穿梭(real-time comments from viewers flying across the screen like bullets)”，英文可以翻譯為“bullet-screen comments”或“bullet screen”。

例句：

一些視頻網站上的低俗彈幕十分不利青少年成長，需設立審查機制。

Vulgar bullet screen comments on some video websites is harmful to the development of teenagers and a review mechanism should be set up.
