写英语日记是提高英语能力的好方法，也是日常生活中的一项好习惯。以下是如何写一篇80词符合日常生活的英语日记的建议：

首先，选择一个适合自己的时间和地点开始写日记。可以选择在晚上写日记，记录一天中的所见所闻和感受，也可以选择在早上写日记，记录前一天的经历和计划。

其次，要尽可能详细地描述自己的经历和感受。可以用一些形容词和副词来描述自己的情绪和感觉。例如：happy（开心的）、sad（悲伤的）、excited（兴奋的）、nervous（紧张的）等。

最后，不要忘记检查自己的拼写和语法错误。可以在写完后再次仔细阅读一遍，或者请别人帮忙检查。

例如：

Dear diary,

Today was a great day! I went to the park with my friends and we played soccer. We had so much fun and I felt really happy. Later, we went to the mall and I bought a new dress. It's so pretty and I can't wait to wear it to the party this weekend. Overall, today was a fantastic day and I'm excited for what tomorrow will bring.

Love,

[Your name]
