我最喜欢的一天是12月21日，因为那一天是我的生日。
On my birthday, I will have a birthday party at home. I’m going to invite my best friends to join in my party. And the highlight of the party will be the birthday cake. Before the party, I’m go to order one which must be big and delicious. Then, at the party, I will make a wish after lighting the birthday candle. In the meantime, my parents and friends will sing a birthday song for me. At last, we’ll enjoy the party.
在我生日的时候，我会在家里举行生日聚会。我将邀请我最好的朋友参加我的派对。派对的亮点是生日蛋糕。在聚会之前，我要点一份必须又大又好吃的。然后，在晚会上，我点燃生日蜡烛后许个愿。同时，我的父母和朋友将为我唱一首生日歌。最后，我们会玩得很开心。派对结束后，我和朋友们将在后院玩得很开心。我会和他们分享我最喜欢的玩具。
After the party, my friends and I are going to have fun in the backyard. I’ll share my favorite toys with them.
，所以，我最喜欢的一天是我的生日！
So, my favorite day is my birthday!

在我生日那天，我总是在家里开生日派对。我总是邀请我最好的朋友参加我的聚会。因为大家最开心的时候是吃蛋糕，所以我总是在聚会前去面包店点一个又大又好吃的蛋糕。在晚会上，我点燃生日蜡烛后会许个愿。同时，我的父母和朋友将为我唱一首生日歌。最后，我们会玩得很开心。派对结束后，我和朋友们总是在后院玩得很开心。我会和他们分享我最喜欢的玩具。
On my birthday, I always have a birthday party at home. I always invite my best friends to my party. As the happiest time for everyone is eating the cake, I always go to the baker’s to order a big and delicious cake before the party. At the party, I will make a wish after lighting the birthday candle. In the meantime, my parents and friends will sing a birthday song for me. At last, we’ll enjoy the party.
