为响应我市全面创建国家卫生城市的号召, 某校开展了以“绿色城市, 健康生活”为主题的英语征文活动。请你以“The green city, the healthy life”为题, 根据表格中的文字提示, 简要描述并适当发表自己的观点, 写一篇90 词左右的英语短文。
1. 倡议首先要点题, 写出原因是什么。2. 确定短文的时态。前面叙述用一般现在时, 后面将要发生的结果可用一般将来时。在写作时要紧扣短文写作的要点, 分清主次, 找到短文的中心, 根据中心内容展开倡议。
“三步三要素法”写倡议书三步: ①倡议对象　②正文　③倡议者三要素: ①倡议的目的②倡议的内容③倡议者的决心和希望
本文用“三步三要素法”写作。特别要按照以下三要素的思路进行写作。要素 1: 先写发出此倡议的根据、原因或目的。只有交代清楚倡议活动的目的、意义, 人们才能理解, 才能采取行动来响应。
要素 2: 倡议的具体内容和要求, 可分条列出, 以求清晰明了。要素 3: 最后写出倡议者的决心和希望, 也可写出如果按倡议做了, 会有什么结果。

本文用“三步三要素法”进行写作, 按三步写作: 倡议对象—正文—倡议者。三要素: ①先写发出此倡议的目的是建立绿色城市, 以便我们能够过健康的生活。用 s that从句引导出目的。② 倡议的具体内容和要求, 用 first f all, als, and 这几个词并列叙述出来。③ 最后用 firstly, secndly 写出倡议者的决心。in a wrd 后总结如果按倡议做了, 会有什么结果。
添彩点: ①“it’s ur duty t”结构对主题有画龙点睛的作用; s that 引导目的状语从句突出了环保的重要性。②巧妙运用了 in this way, as fr me 和 in a wrd 起到了递进的作用。
