Last Sunday, I showed Tom, the friend from the USA, around the city. This was the first time that Tom visited my hometown, and he found the trip excited.

Early in the morning, I took her to the park near my home. He was astonished to seeing so many people did exercise in the park. Then, we went to the museum. From the exhibitions, he learned a lot at the history of the city. After leaving the museum, we went downtown and found it was crowded with quite a lot of building. On our way to home, Tom said he was really amazed by that he found. But he hoped that he would have chances to come here again.
