大家都知道，food是食物的意思，thought是思想的意思。food for thought连在一起，就是指“引人深思的事情”。刚才我们说到的，什么买票上月球啊，这些事情可能发生，也可能是空想，但是不管怎样都会引起大家的思考。

例句：

I heard something interesting at a seminar. If you don't like long meetings, ask everyone to stay standing. Now I don't know if employees at my company would try that idea, but it's certainly food for thought.
我在一次研讨会上听到了一种很有意思的说法，说如果你不喜欢开长会，就让所有人都站着。我不知道我们公司的人是否愿意尝试这种做法，但这确实很有意思。

Consider this: getting lost in a daydream can help you deal with difficult situations in your life. It can not only relieve stress, but stimulate solutions. Hopefully, this gives you some food for thought.
想想看，白日做梦能帮助你面对生活中遇到的困境，不仅能够帮助你释放压力，有时还能刺激你找到出路。希望这么说能引起你的思考。
