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 build
a clear picture of the Underground in my city. They are together with this mail.
In your email, you also said workers were building more lines. I'm sure your city is developing fast.
Maybe you can send me a few photos of your city today. I really want to see the changes taking place
there. I'm happy for you to live there in an ancient city with such a new look!
So much for now. I'll write soon again. Best wishes!

洪波你好！
得知你所在城市的变化很开心，虽然西安才只有一条线路，但你可以乘坐地铁出行真是个好消息，在伦敦我们有12条地铁线了。顺便提一下，“subway”这个词是美国人称呼地铁的，我们称之为"the underground"。
伦敦地铁非常出名，有几个理由，第一，部分地纤哪旦铁线在1863年开通，是世界上最古老的地铁线。第二，伦敦地铁是在1890年首次使用电力机车的地铁。第三，目前伦敦地铁是继上海地铁后第二大的地铁网络系统，这里有270个站台和402公里的隧道，而且，伦敦市本身就让交通系统很出名！我有几张照片可以缓返让你更清楚的认识我们城市的地铁。我附在邮件里给你。
在邮毁扰件里你说工人们已经在建设更多的线路，我相信你们的城市一定发展迅速。也请你发几张你们现在城市的照片给我，我真的想看看发生了的改变。很高兴你住在一个有着如此美丽容貌的古老的城市！就说这么多了，很快我再写给你，祝好！
