今天是星期天，我和我的宠物小狗去公园散步了。我的小狗叫“小黑”，它是一只黑色的小狗，非常可爱。

我们走在公园里，小黑一边走一边摇着尾巴，好像在跟我说话。它看到一只小鸟飞过来，就追着小鸟跑，但是小鸟飞得太快了，小黑追不上。

我们走到了湖边，小黑看到了一只正在游泳的鸭子，就兴奋地跑过去。但是它太兴奋了，一不小心掉进了湖里。我赶紧跑过去，把小黑捞了起来，它的毛都湿透了。

我抱着小黑，走到了湖边的长椅上，等它的毛干了。小黑蜷缩在我的怀里，好像在感谢我。我轻轻地抚摸着它的头，心里感到非常温暖。

过了一会儿，小黑的毛干了，我们就继续散步。小黑好像更亲近我了，总是跟在我身边，不肯离开。我感到非常开心，因为我知道，小黑是我的好朋友。

今天的散步很愉快，我和小黑一起度过了一个美好的下午。我希望，我们能一直这样，永远做好朋友。

Today is Sunday, and my pet dog and I went for a walk in the park. My dog's name is "Xiao Hei", and it is a cute little black dog.

As we walked in the park, Xiao Hei wagged its tail as if it was talking to me. When it saw a little bird flying by, it chased after it, but the bird flew too fast and Xiao Hei couldn't catch up.

We walked to the lake, and Xiao Hei saw a duck swimming, so it ran over excitedly. But it was too excited and accidentally fell into the lake. I quickly ran over and pulled Xiao Hei out of the water. Its fur was all wet.

I held Xiao Hei and walked to the bench by the lake to wait for its fur to dry. Xiao Hei curled up in my arms, as if thanking me. I gently stroked its head and felt warm inside.

After a while, Xiao Hei's fur dried, and we continued our walk. Xiao Hei seemed to be closer to me and always stayed by my side. I felt very happy because I knew that Xiao Hei was my good friend.
