Today, I went to the park with my parents. I saw monkey, giraffe and so on. When we took a break in the lake, I saw a lot of goldfish in the lake. People threw food into the water, then suddenly all the fish came and ate the food. It was a crowd of fish, and I was shocked, but then they went away quickly. 
今天，我和爸爸妈妈去公园了。我看到了猴子，长颈鹿等。我们在湖边休息的时候，我看到湖里有很多金鱼。人们把食物扔到水里，突然所有的鱼都来抢食物。很大一群鱼，我震惊了，不过很快它们就散开了。
