Believe it or not, I was once a babysitter for a day.

　　That was a day in July. I went to see my grandma. My aunt was busy working while my grandma had to cook. So I decided to look after my cousin.

　　My little cousin was only 3 years old and she was very cute. In the morning I fed her some food. In the afternoon I told her some stories and then we played together.

　　In the evening when I got home, I felt tired but I was happy.

　　不管你信不信，我曾当了一天的保姆。

　　那是七月的一天。我去看望奶奶。我姑姑忙于工作而奶奶得做饭。所以我决定照看我的小表妹。

　　我的小表妹年仅3岁，很可爱。早上我喂她吃东西，下午我给她就爱你个故事，之后我们一起玩。

　　晚上当我回家时感到很累，但是我非常高兴。
