THE ENGLISH

Hello, Everybody.I am a fourteen-year-old girl. I am a Chinese and I love English very much! My dream is going to London to learn more about the culture about of England. However, I find it difficult to understand the British speaking English. They speak neither slowly nor clearly. Although sometimes they slow down the speed of speech, but I still could not understand them. My English teacher never spoke English like that! I think that the English understand each other, but I do not understand them! Do they speak English?
大家好，我是一个十四岁的女孩。我是一个中国人，我非常喜欢英语！我的梦想是去伦敦学习更多有关英国文化。但是我发现听懂英国人讲英语是非常困难的。他们讲的既不慢，也不清楚。尽管有时他们放慢了速度讲话，但我仍然听不懂。我的英语老师从来不会这样讲英语！我想，英国人之间互相听得懂，但是我却不懂他们的话。他们说的是英语吗？

[Good work.  It is strange, but many non-English speaking people tell me that they can understand Americans better than the British, even though the English language originated in Britain.  One man said as a joke that the Americans and British are two peoples separated by a common language.

You could say "Although sometimes they slow down..., I still could not..." or "Sometimes they slow down..., but I still could not..."  Both are correct, but you cannot use 'although' and 'but' together.]
