(Keep) one's fingers crossed (for someone or something)
Cross one's fingers

事随人愿，心想事成

在英语会话时，你是不是常常看到西方人一边说：“Let's keep (our) fingers crossed“一边将中指和时食交叉，有时候用一支手有时候两支手一起做这个动作呢？

你知道是什么意思吗？

这其实是西方人一种祝好运的习俗和习惯，希望事情如人所愿的顺利，一切成功。

例句:

我希望你周六的比赛能赢。我祝你好运。

I hope you win the race Saturday. I'm keeping my fingers crossed for you.

让我们祈祷这个周末不要下雨

Let's keep our fingers crossed that it doesn't rain this weekend.

我要杀了那只吃人的老虎。祝我好运吧！

'm trying to kill that man-eater tiger. Keep your fingers crossed for me!
