正文有缩进式和齐头式两种。每段书信第一行的第一个字母稍微向右缩进些，通常以五个字母为宜，每段第二行从左面顶格写起，这就是缩进式。
但美国人写信各段落往往不用缩进式，用齐头式，即每一行都从左面顶格写起。商务信件大都采用齐头式的写法。

Beloved father and mother:
How do you do!
If you are the water, then I am the small fish in the water; if you are the blue sky, I am the little bird flying in the sky; if you are the sea, I am the coral reef in the sea.
It is very early to tell you what I have said in my heart. I have never had a chance to tell you about it in the middle of the exam.
When I was born, you were afraid of money and sent me to the countrys aunts house. An aunt to me very well, when I get married daughter, I live very happily. At the age of nine, you sent me to the home of the great man in the city, where I had been suffering for three years because they did not see me as a man. Three years later, back to you, I think I will be very happy and happy, but you...
Because Im not growing up with you, you dont trust me, you know how I want your understanding and trust!
Remember that year, one night, you know that I called the countrys aunt, you gave me a meal, looked at the body of blood, I couldnt help crying, but you are screwing my ears, my heart is very painful, more painful. And let me kneel on the floor brick for two or three hours. You too did not understand me, they bear bitter hardships to bring me up, shouldnt I call them?
You know, how I hope to get your understanding!
On that day, the teacher asked to pay the book for twenty yuan. When I speak to you, your great response, Dad shouted to me: \"tomorrow let your teacher to write a check up, is not really to pay!\" your mother is saying: \"I ask tomorrow!\" you know, you hurt her pure heart ah! The second day, the teacher call you, after confirming you dont apologize to me, but that day for money!
You know how I want to get your trust!
Its the wind! You blow a little faster and wake up your mom and dads brain! Let them wake up!
Small fish also need freedom, birds need to understand, and coral reefs need trust, isnt it?
Mom and Dad, just ask the wind to tell you what I think!
This
Salute!
Your daughter: X

一件难忘的事作文用书信格式400字【八】
亲爱的妈妈：
“世上只有妈妈好，有妈的孩子像块宝……”每当听到这首歌的时候，我都会想到您那熟悉的身影。您把许多的爱都给了我，然而您却自己过着平凡的生活，并没有得到一丝的爱。
记的我九岁的时候，我从外面打棒球回来，我就感觉像到了太阳一样热似的，热的受不了。就洗起了冷水澡，我刚洗完，您就回来了，说道：“哎呀，今天我们小虎真不简单，自己动手洗澡了。”洗完后不到十几分钟，我便咳嗽了起来。您问道：“小虎，你是不是用洗了凉水澡啊？”我回答说：“是呀妈妈，怎么了。”您急忙给我穿了大衣，背起我就往医院跑。我曾多次向您说到：“让我下来，让我下来，我要自己走。”可您什么话也不说，直奔医院。
汗水湿透了您的衣服，可您却不觉的累，我在您的背上轻声哭泣。到了医院才得知我感冒严重了，医生给我开了药，打了针，叮嘱我不管多热，都不能用冷水洗澡，更不能喝凉开水，休息几天就好了。回到家后，您在我旁边为我端药、端饭，就连晚上您也不睡觉，在我旁边守着我，直到我病好。
像您这样点点滴滴的爱，说也说不尽。在这里 对您的爱只能凝结成一句话：妈，您辛苦了！我爱您！
祝您身体健康万事如意！
您的女儿：xxx
20xx年xx月xx日
