高中英语改错怎么改？
I just came back from Britain in last week. I was luckily enough to be one of the students visit the UK from Feb.16 to 28. We paid a visit to many places, like London, Oxford or the Lake District. I learned much about British culture and history in London, where was my favorite. I also liked Oxford, in which I see many old buildings. The Lake District was beautiful, but it was pity that it rained heavily when they were there. The most excited thing for me in Britain was that I made a lot of friend there.
