写作专题

Designing a poster

写作指导
海报写作属于应用文写作。海报是一种宣传广告,其内容是提供活动

信息、介绍产品或说服别人等。
一、海报的写作格式和内容

海报一般由标题、正文和落款三部分组成。
1.标题

海报的标题写法较多,大体有以下几种形式:
(1)单独由文种名构成,即在第一行中间写上“海报”字样。

(2)直接由活动的内容承担题目,如“影讯”、“球讯”等。
(3)可以是一些描述性的文字,如“××风采”等。

2.正文 海报的正文要求写清楚以下内容: (1)活动的目的和意义。 (2)活动的主要项目、时间、地点等。 (3)参加的具体方法及一些必要的注意事项等。 3.落款 要求署上主办单位的名称及海报的发布日期。 以上的格式是就海报的整体而言的,在实际的使用中,有些内容可 以少写或省略。

二、海报写作的注意事项
1.海报一定要真实具体地写明活动的地点、时间及主要内容。文中可

以用些鼓励性的词语,但不可夸大事实。
2.海报的文字要求简洁明了,通俗易懂,篇幅要短小精悍。

3.海报的版式可以做些艺术性的处理,以吸引观众。

典例展示
假设最近你应学生会要求设计一幅关于环保的海报。请以下面所示图 片为海报宣传画,并根据图片写一段 150词左右的说明性文字。要点 如下: 1.简要描述图片的内容; 2.气候变化带来的灾难以及启示; 3.我们应该如何做?(至少写两条建议) 参考词汇:北极熊polar bear

写作步骤 一、谨慎审题,合理谋篇
海报是一种宣传广告,属于应用文体。要求语言简洁,通俗易懂。

海报应具有通知性和动员性,能够吸引读者。根据题目要求,文章
可分为三个部分:第一部分展示问题,第二部分陈述原因,第三部

分提出倡议和建议。
二、列出要点,初步成稿

根据需要确定时态。海报叙述的是新闻信息、动态等,应该以一般
现在时为主。

三、巧用连接,通顺全篇 Global Warming Prevention The past ten years has witnessed such great changes in our environment that various problems and disasters have appeared one by one.In a very creative manner,this cartoon presents a scene.A polar bear seats itself nervously on a small block of ice and tries to grasp something with all its efforts.The polar bear looks terrible since the ice is melting every second.

Owing to the rising global temperature,the icebergs are melting
at a shocking rate.It is reported that the sea level has risen 10 to 25 cm

over the past 100 years.The famous city of Venice is likely to
disappear.But this can be avoided if the rise in the sea level can be

stopped.
Therefore,a growing number of people have come to realize the

necessity of solving this issue.One major measure is to cut down
carbon emissions.However , we have to be united and make joint

efforts.And then our planet can be saved,so can we ourselves.
