在另一个场合，我在纽约市的地铁里成功购买下载了一本书，那是在仅仅短暂停靠两站的升降平台上完成的。
On another occasion, I managed to buy and download a book on a New York City subway train, during a brief two-stop stretch on an elevated platform.
我想我可能也犯了一些小错误。我应该说，我刚添加了另一个不同的下载站点，请你再试试。
I think I have some grammere mistake too, i should say: I have added a different download link at different web site, u can go try.
