如何写海报
海报是向大众发布某种消息的布告。
海报的形式多为招聘广告、活动宣传和人物介绍。
英文海报的内容常为球讯、影讯、商业报道、展览会、报告会、专题讲座等。
一般的英语海报由标题、正文和落款组成。
1.标题
海报中往往把内容作为大字标题。
如:
FootballMatch,FilmNews,GoodNews,NewYear'sEveEntertainment或者注明Poster等字样。
2.正文部分
正文部分要写清楚具体内容。
活动内容、地点以及参加规定、主持或举办单位等。
语言多用十分简略的形式,开门见山地说明主题、活动内容。
活动时间和活动地点另起一行。
最后提出活动要求和注意事项。
3.落款
出海报的单位署名通常放在右下角;日期位于署名的下一行,既可以写在右下角,也可以写在左下角。
另外:
海报写作的注意事项还有:
(1)时态:
用一般将来时和一般现在时。
(2)语言:
海报文字要求简洁明了,篇幅要短小精悍。
文中可以用些鼓动性的词语,但不可夸大其词。
(3)要求:
海报一定要具体真实地写明活动的时间、地点、主要内容及参加规定。
