英語作文日期寫在信紙的右上角。在信封的左上角寫「寄信人」的名字和住址。
英文書信的格式及信封的寫法：
1、信紙的右上角寫上日期，如September8，也常用簡寫Sep.8；非正式的信件，年代常省略；正式的'書信則不只會寫上年代，還會把發信者的住址寫在日期的上方。
2、接下來在信紙的左方寫收信人的稱呼語，通常用Dear開始，再接著寫名字(一般都用firstname)，如DearSusan(親愛的蘇珊)；至於名字的後面則通常打上逗號或留白。
3、稱呼語寫完後，通常會先空一行才開始寫信的本文。
4、本文結束後，再寫上結尾語，如Seeyou(再見)、(With)Bestwishes(祝你平安)、Yoursalways(永遠是你的摯愛)、Yoursever(永遠愛你的)、Yourfriend(你的友人)、Trulyyours(摯友)、Sincerelyyours或Yourssincerely或Sincerely(最誠摯的友人)、Love(愛人，避免用在兩個男士間的信件)…等。

英語寫信時要注意英文地址的寫法與中文完全不同，地址的名稱按從小到大的順序寫。在一般的社交信中，信內收信人的地址通常省略，但是在公務信函中不能。將收信人的姓名、地址等寫在信頭日期下方的左角上，要求與對信頭的要求一樣，不必再寫日期。每段書信第一行的第一個字母稍微向右縮排些，通常以五個字母為宜，每段第二行從左面頂格寫起。
1、The Mid-Autumn festival, every family reunion together, in favor of thebalcony and enjoy the moon while eating moon cakes, even my family is no exception.
2、My family and I together in the balcony on moon. Just dump the moon rising from under a piece of pure, and the moon bright fluorescent, slowly,slowly turned white. Quiet moonlight sprinkled on the ground, the whole world is on the quilt with a layer of silver light, the town was hanging over the thin silver yarn. Through the clouds, the moon will glowsprinkled on the road, as if the road is paved with silver. It will also be the moonlight reflected in the water, evening the wind blows, the river is sparkling.
3、The moon like a shy little girl, in a short while hiding in the clouds, and the cute little head out from the cloud, the earth became dreamy silver. Looking at the moon, and can not help but reminds me of the story of chang e, people is in honor of the goddess of the moon to August 15 as the Mid-Autumn festival reunion hoping people. Also reminds me of a well-known celebrated the stillness of the night: bright moonlight before bed, doubt is frost on the ground. Look at the bright moon, bowed their heads and remembering home. This poem represents the poet li homesick feelings. From time to time make me think of the garrison the frontier soldiers in the Mid-Autumn festival this day cannot be reunited withhis family.
