Last weekend we had a birthday for our classmate Zhang Xiaohui. She is younger than me, but I am shorter than her. And she looks stronger. Of course she is heavier than me. We went to a shop to buy a present for Xiaohui. What did we buy? We bought a doll for her. Because she told me " I haven't got a lovely doll." When she got our present she looked excited. She was very happy. We went to the zoo. We saw elephants. We wanted to row a boat in Jingming park, but it was later, we had to went home. We had a good time on that day.
