在听、说、读、写四种基本技能中，“写”对英语学习者来说可能是最困难的。要提高“写”的技能只能通过写，有人说 “Learn to write by writing”就是这个意思。
写英文日记也有一定格式，这主要指日记的开头。日记开头总是先写日期、星期和气候情况，通常从正文上一行的顶格处写起。日期的顺序可以是“日、月、（年）”，也可以是“月、日（年）”；星期可以写在日期之前，也可以写在日期之后，还可以干脆不写；天气情况（如fine, cloudy, windy, rainy等）可以紧接在日期之后写，也可以写在第一行的最右端，还可以干脆不写。

We worked in three groups. "Faster, faster! We mustn't fall behind the others!" That was the thought in everybody's mind.
Evening came before we realized it. We put down our sickles and looked at each other. Our clothes were wet with sweat, buy every face wore a smile.
We harvested thirty mu altogether. That was not bad for the first day. Tomorrow we shall certainly do better—much better.
Last November I was fourteen. Papa gave me this diary then for a birthday present.
“What shall I write in it?” I asked him. It's a beautiful diary, but the pages are rather large.
Papa smiled and kissed me. “Write the story of Mademoiselle Desiree Clary1,” he said. Then a worried look came into his face. Since our great revolution2, he has often had that look.
A few days after my birthday, Papa suddenly died. So I haven't been wri?鄄ting my diary; I've been too sad. But I'm starting it tonight because I'm too worried to sleep. The police arrested my brother Etienne today. Tomorrow I must go to the Town Hall with his wife, Suzanne. We must try to save him. If we fail, perhaps he'll be guillotined3. It's a terrible thought...
