一篇文章通常可分为三个部分，即开头、正文和结尾。这三个部分安排是否得体，直接影响到文章的质量。文章的开头一般来说应尽量做到开门见山，用简单明白的叙述引出文章的话题，使读者了解文章要谈论什么，一下于引起读者的兴趣。 作文常见的开头形式大致有以下几种： 1、开门见山，揭示主题 文章一开头就交待清楚文章的主题是什么。如How I Spnt My Vacation(我怎样度假)的开头是： I Spnt my last vacation happily. 下面是题为Honsty(谈诚实)一文中的开头： Honsty is on of th bst virtus.An honst man is always trustd and rspctd.On th contrary, on who tlls lis is rgardd as a liar,and is lookd upon by honst popl. 2、交代人物、事情、时间或环境开头 在文章的开头，先把人物、事件和环境交待清楚。例如A Trip to Jinshan (去金山旅游)的开头： Th day bfor ystrday my class wnt on a bus trip to Jinshan. Th bus rid thr took thr hours. Th long trip mad us vry tird, but th sight of th bautiful sa rfrshd us. 3、 回忆性的开头 用回忆的方法来开头。例如A Trip to th Taishan Mountain(泰山游)的开头是： I rmmbr my first trip to th Taishan Mountain as if it wr ystrday. 4、概括性的开头 即对要在文章中叙述的人或事先作一个概括性的介绍。如Th Happinss of Rading Books(读书的快乐)的开头： Popl oftn say that gold and silvr ar th most valuabl things in th world. But I say that to rad books is mor valuabl than anything ls, bcaus books giv us knowldg and knowldg givs us powr. 5、介绍环境式的开头 即开头利用自然景物或自然环境引出要介绍的事物。如An Accidnt(一场事故)的开头是: It was a rainy and windy morning. Th sky was gloomy, th tmpratur was low, and th strt was narly mpty. I was on my way back to school. Suddnly, a spding car cam round th cornr. 6、交待写作目的的开头。 在文章的一开头就交待写作目的，如通过文章要表扬谁，批评谁，或说明一个什么问题等。如Pollution Control(控制污染)的开头： In this articl I shall draw your attntion to th subjct of pollution control.
