如果有人说 to bridge the gap, 意思就是把两个完全不同的事情联系起来，汉语里的意思是缩小差距。

例句

The government will never be able to bridge the gap between the rich and poor.

Grandparents can help to bridge the gap between generations by telling their grandchildren stories about their own childhood.

You'll need to study a lot harder over the summer to bridge the gap between school and university!

请注意

英语里的另一个短语是 cross a bridge when you come to it, 这个短语的意思是车到山前必有路。

The roof of the house may need to be replaced if we have a bad winter, but I'll cross that bridge when I come to it.
