     I went to Ottawa last December. It was my first time to Canada. Because I couldn't go to many places in

Ottawa in two days, I learnt a little about the beautiful city. This summer, I went to the city again. A friend

once told me Ottawa was the most beautiful in May. But I arrived in late June. Like I did, travelers from

different countries enjoy having their holidays there. I lived in a small but nice hotel. There were a lot of stores

and restaurants near it.

     People in Ottawa are very friendly. One day, I got lost after I went out of a bank. It was hard for me,

because my English was poor. Then I saw two boys passing by. I asked them for help. They told me the way

to my hotel. Finally, one of them went back with me. He spoke French well! Two weeks later, I left Ottawa.

     I love Ottawa. I hope to visit it again some day.
