范文赏析
The green city, the healthy life
As citizens of the city, it’s our duty to help build a green city so that we can live a healthy life. How can we make our city greener
First of all, we can reduce air pollution by riding bicycles. Also, it’s better for us to put rubbish into the rubbish bin. In this way, we can keep our city clean. And we’d better plant more trees to protect the natural environment.
As for me, I’ll try my best to make our city cleaner and more beautiful. Firstly, I can save water by taking shorter showers. Secondly, I can save energy by turning off the lights when I leave the room. In a word, everyone can do something to make a difference.
名师点评
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 so that从句引导出目的。② 倡议的具体内容和要求, 用 first of all, also, and 这几个词并列叙述出来。③ 最后用 firstly, secondly 写出倡议者的决心。in a word 后总结如果按倡议做了, 会有什么结果。
添彩点: ①“it’s our duty to”结构对主题有画龙点睛的作用; so 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 for me 和 in a word 起到了递进的作用。
本节课主要复习所学词汇; 并总结巩固构词法。
