日記的正文是日記的主要部分，寫在星期和日期的正下方，可以頂格寫，也可以內縮3至5個字母的空間。由於記載的內容通常已經發生，謂語動詞多用一般過去時。但也可根據具體情況，用其它時態。如：記敘天氣、描寫景色，爲了描寫生動，可以使用現在時，以表現當時的情景。再如文後發表感想或評論可用現在時態或將來時態。記日記力求簡單明瞭，有連貫性。若有文字提示，則應重視提示，把握要點。在句式上儘量使用簡單句，以防繁雜，造成語法、句型錯誤。
一、英文日記格式
英文日記通常由書端和正文兩個部分組成。日記常以第一人稱記下當天生活中的所見、所聞、所做或所想的事情。中、英文的日記三格式大致一樣。英語日記的書端是專門寫日記的日期、星期和天氣的。左上角是日期(年、月、日)、星期。右上角寫上當天的天氣情況，如：Sunny, Fine, Rainy, Windy, Snowy, Cloudy等。
1.日期表達有多種形式。年、月、日都寫時，通常以月、日、年爲順序，月份可以縮寫，日和年用逗號隔開。例如： December 18, 2003 或者 Dec. 18, 2003
A) September 1, 2004或September 1st, 2004也可省略寫成Sept. 1, 2004或Sept. 1st, 2004;B)the 1st of September in 2004(月份不可以縮寫)
B)只有月、日
September 1或September 1st(月份可以縮寫)
C)只有年、月
September 2004或the September of 2004(月份不可以縮寫)
以上的1或1st都應讀作the first。
2.星期也可以省略不寫，可將其放在日期前或後，星期和日期之間不用標點，但要空一格，星期也可縮寫。如：
Saturday, October 22nd, 2004;October 22nd, 2004 Saturday
3.天氣情況必不可少。天氣一般用一個形容詞如 :Sunny, Fine, Rainy, Snowy 等表示。寫在日期之後，用逗號隔開，位於日記的右上角。如：
Saturday, March 4, 2004, Windy;1st January, 2004, Fine
1. 注意日期、星期和天氣的書寫位置。
日期和星期要寫在正文的左上角，其順序多是“星期 + 月、日、年”，也有把星期放在後面的，如“ 2003 年 11 月 22 日，星期一”可寫爲“ Monday November 22， 2003 或 November 22， 2003 Monday ”。
日記的第一行，要寫明年、月、日與星期，然後要寫明當天的氣候狀況，如果是遊記，還要寫明地點。
這一部分中天氣狀況比較難寫。下面是一些常用的描寫天氣的英語詞語：
晴 clear 陰 overcast 多雲 cloudy 小雨 light rain
大雨 heavy rain 毛毛雨 drizzle 陣雨 shower
東風 east wind 南風 south wind 西風 west wind
北風 north wind 西南風 southwester 東南風 southeaster
東北風 northeaster 西北風 northwester
氣溫 temperature
炎熱 scorching heat 寒冷 icy cold 下雪 snow

I am free now as I am spending my winter holiday.
Although we have some homework, we can finish them in several days. And the rest time we can make good use of. My god! We have been very tired after hard studying. In winter holidays, I want to have full sleep and eat good food in order to replenish myself. Last but not the least, I will have a good rest.
I have rested for a week. I began to feel bored. So I went out with my friends. They are my best friends in the middle school. We didn’t go to someplace special. We just saw the other. We had lunch together. While we were having lunch, we were still talking about the new school and new friends. Yes! A year later, we have grown riper. And we learned much more things and got new life. We haven’t enough time to play, to waste and to lose the way. We only have two years. Two years to go, we will get the real life which belongs to us.
2015英語日記格式範文二：
英文日記和漢語日記一樣，是用來記敘一天中所發生的有意義的事情或對將來的打算等。日記可分爲記事、議論、描寫及抒情等。
記事型是用英語記述當天自己生活學習中發生的事情。
議論型是對生活中的`某一事情或情況現象談自己的看法，發表議論。
描寫型或抒情型，則是對某人物事物的特徵做細緻的描述，或針對某事物抒發自己的感情。1.格式：一般是在左上角記上當天日期，星期，時間的排列法與書信一致，星期寫在日期之後;右上角寫上當天的天氣情況，表示天氣情況的詞一般是形容詞，如：fine (晴朗的)，cold (寒冷的)，snowy(下雪)，sunny(陽光充足的)，rainy(下雨的)，cloudy(陰天的)等。日記的小標題寫在下一行，也可省略不寫。
2.時態：寫日記的時間一般是在下午、晚上，有時也可以在第二天補寫。因此，日記中所記述的事情通常發生在過去，常用一般過去時;但當記述天氣、描寫景色或展望未來時，可以用一般現在時或一般將來時。寫法大致和寫漢語日記相同，都是在正文之前有日期、星期幾及當天的天氣情況。注意內容表達要清楚連貫、準確。
