我没有带任何多余的备份。

And I didn't bring any spare copies.

Again, I don't have data to back this up, but just common sense suggests to me that the common case is if I'm on the subway platform I want to get on that train and maybe I want to get back and where are those two buttons, right?

此外，我没有数据来备份这个，但是常识告诉我，常见的情况是,如果我站在地铁站台上，我想乘上地铁,可能我还想回来,那么哪里能找到这两个按钮，对不？
