去 spice something up 的意思就是放更多香料在食物或饮料里使其更有滋味。另外你也可以 spice up 一段讲话、一个表演或活动：在这里就不是放调料了，而是在其中加入更有趣味，引人入胜的内容。

例句

This salad was a bit boring so I spiced it up with some chilli sauce.

Martin's speech was really dull. He should have spiced it up with some jokes!

请注意

如果某人被形容为 as salt and pepper, 就是说他原来深色的头发已经开始掺杂白发了。

例句

Mark used to have lovely black hair but now he's salt and pepper. But you know what, I like it!
