We visited the Liberty Bell when we were in Philly.

我们在费城时参观了自由钟。

The bell has since become a symbol of freedom and can be admired in the Liberty Bell Center.

这座巨钟从此便成为自由的象征，现在您可以在自由之钟中心欣赏这一历史文物。

My office happens to be on Independence Square and now and then I have occasion to direct a tourist to the Liberty Bell or fill him in on a little of the history of Philadelphia.

我的办公室正好在独立广场，因此我偶尔会为去独立钟的游客带路，一路上给他讲一些费城的历史。
