其实周记就是每周一记，四年级也好，初中也好，高中也好，要求都是一样的。老师让大家写周记，就是每周把自己的所看到的、听到的、想到的、经历的东西记下来，形成的文字片断或一篇文章，一周写一则。
如果是一个片断，将事情写清就行了，当然，时间充裕，你可以将前因后果，你的想法补充完整，形成一篇文章。不论无论，周记没有什么特别的格式，跟我们平时说话写文章一样，要求就是条理清楚地说清一件事、一个想法。
周记的关键是要真，真事、真情、真想，不要虚构。用力表达你正经历的、正思考的.事，对提高你的写作能力是有帮助的。
周记的基本格式是写明日期(包括星期,年,月,日,气候),标题,主题内容,末尾写上署名.
日期的格式: 星期，年,月，日，天气

July 15,2007 Sunday Sunny
Today is Friday. It is my thirteenth birthday. I got up very early in the morning and put on my new clothes happily. My parents bought me the new clothes as my birthday presents. I went to school earlier than before. I invited many of my classmates to come to my birthday party in the evening.
Evening came at last. Many of my classmate came to my home. they bought me lots of beautiful presents. they all said,"Happy birthday to you!" We sang birthday songs my parents brought out a big birthday cake, saying, "We love you for ever. Happy birthday!"
At the end of the party, we ate the birthday cake and some other delicious food. How happy I was!
It was Sunday. Our teacher Mr Zhu led us to a park lly we go to the park to spend our holiday. But today we went there to take part in voluntary labour.
We got there at nine o’clock. Mr Zhu divided us into three groups and then we began working.
the students in Group One planted trees and watered flowers. the studentsin Group Two were busy collecting litter left by the tourist. they also cleaned the benches in the park. I was in Group Three. We went to the children’s playground and cleaned all the equipment there. We worked very hard.
