A Happy Day Yesterday was a happy day for me. In the morning, I woke up early and saw the sun shining outside. Then, I had a delicious breakfast with my family. After that, we went for a walk in the park and played some games together. In the afternoon, I went to my friend's birthday party and had a lot of fun there. We played games, sang songs, and ate yummy cake. In the evening, I watched my favorite movie with my family and had some popcorn. I went to bed feeling happy and satisfied. It was a wonderful day! 上面是一篇简短的英语作文,描述了一个开心的一天。通过描述具体的活动和感受,让读者感受到作者的快乐和满足,同时也能够提高英语写作的能力。
