Dear Xiao Hua,
I have just come back from a trip to the United States. I had a very good time there.
I first went to New York. It is really a very big city. I saw quite many skyscrapers there. But the Twin Towers of the World Trade Center are no more to he seen. Two days later I went to Los Angeles. I visited Hollywood on the day I got there. After that 1 spent a whole day in Disneyland. It is really a wonderful place you shouldn' t miss.I also went to Reno, Nevada.
There is a beautiful lake named Dahu.The scenery there is attractive!
I hope you will take a trip to the United States some day.
Love ，
Xiao Ming
