Last week, I take part in the Cultural Exchange Week but enjoyed myself in England. I visited the city museum and several place of interest, which made me have better understanding of the English society, culture and history.
What's more, I was luckily enough to meet my pen friend Tom there. I stayed at his home. And I'll never forget the days when we spent together. When I left England, he offered to me a dictionary as a gift. It's of great help for me to learning English. I will make full use of them and learn English well.
I hope Tom will come to China when it's convenience for him!
