Hi Hongbo,
I’m so glad to read about the changes talking place in your city.It’s really good news that you can travel by subway in Xi’an,though there’s only one line there.Here in London we have twelve lines.By the way,we don’t use the word “subway” here.It’s American English.We call it “the Underground”,instead.
The London Underground is very famous.It’s famous for several reasons.First of all,part of the underground railway today is the oldest in the world,which opened in 1863.Secondly,the London Underground is also the first line to have electric trains,in 1890.Thirdly but not the last,the London Underground is the second largest metro system in the world,after the Shanghai Metro.There are 270 stations in the Underground and it has 402 kilometres of tracks(轨道).What’s more,the city of London itself helps make the transportation system famous!I’ve got a few photos to help you bui
