My vacation was very interesting. I did my homework on first day. I played table tennis on second day. I watched TV on the third day. I went shopping on the fourth day. But I liked my going shopping best.

　　On Sunday, I went to a shopping center with my mother. The shopping center wasnt far from my home. It took us about ten minutes to get there on foot. The shopping center was very big. There were all kinds of things. Every day a lot of people go there to buy things. It opens at eight in the morning and closes at nine at night. Now, I was helping my mother buying things. I had a shopping list in my hand. We were looking for things on the shopping list. After staying in the shopping center for about two hours, we got all the things and walked home.

　　What did you do when you were on vacation?
