And that's largely because those symbols don't just mark a particular event or moment.

这在很大程度上是因为这些符号不仅仅是标记一个特定的事件或时刻。

According to Time, the cover of its 14 December issue marks only the fifth time the publication has used a red " X" , a symbol it reserves for " some of the worst foes humanity has faced in the magazine's history" .

据《时代》杂志报道， 该刊 12 月 14 日的封面标志着该刊第五次使用红色“X”，这是它为“该杂志历史上人类所面临的一些最恶劣的敌人” 保留的符号。
