假如你叫李华，你的美国笔友John在来信中谈到低碳生活这个话题。最近几个月你校倡导学生过低碳生活、过节约生活、做有责任感的公民，引导学生从出行、购物、用水、家电和餐具使用等方面反省自己的生活方式。请你用英文给John回信。回信要点如下：
1.你对低碳生活的理解；
2.你校开展的活动；
3.你最近生活方式的改变(至少选取三个方面)
注意：1.词数120左右；
2.参考词汇：低碳生活low carbon life(style)
3.信的开头和结尾已为你写好(不计入总词数)

解析：本文是一篇材料作文，题干虽然所提供的内容比较多，但是实际给出的要点却比较少，其开放程度同样较大。不过考生对此话题非常熟悉，写起来有话可说。题干内容多，给考生带来处理要点的难度，因此写好本篇书面表达的关键是：选择要点，挖掘要点和正确表达。题干所提供的内容比较多，在表达时无需面面俱到，这就要根据题干选择我们表达时必须的要点：围绕“对低碳生活的理解、学校开展的活动、最近生活方式的改变”等三个方面结合“做有责任的公民，过低碳生活”去挖掘要点。本篇书面表达的基本时态为现在时(一般现在时和现在完成时)。偶尔会用到一般过去时，如：提及学校组织的活动时就要用到。但是接着讲“最近生活方式的改变”时，就要用现在范畴的时态了。
【亮点说明】范文长句多，充分展示了作者驾驭句子的能力。复合句固然长，但是简单句也显得不那么简单，也比较长。比如“For example, instead of asking my parents to drive me to school, I take a bus to and from school.”就达20个字。全文共8句(不包括所给的部分)，涉及简单句3个，复合句5个，开头句和最后依据非常吸引人的眼球。开头句中用了“with”复合结构“With the environment problem ing into attention”，还用了非常靓丽的复合句 “it is extremely important that we take action to protect our planet”.最后一句更是错综复杂：总体说，这是一个复合句，由主句“The TV and the puter are important entertainment for my family, but we sometimes read instead”加“which”引导的非限制性定语从句“which, I think, may help relieve the shortage of electricity”；主句中包含了并列句“but we sometimes read instead”；该句中还用了一个插入语“I think”对整个长句起到了缓冲的作用。短语“make a difference，In response to，range from transportation to water saving”等的使用也彰显了作者扎实的语言基本功。
