如何写好调查报告近几年来,很多大城市都投放了共享单车(shared bikes)。由于方便停放,绿色环保,且能锻炼身体,它们作为代步工具很受大家欢迎。但是,也有人对此持质疑的态度。请根据以下调查的结果,写一则有关共享单车的调查报告。
一、审题定调1.确定体裁:本单元的写作任务是调查报告,内容是共享单车的使用情况。调查报告是针对某一现象、某一事件或某一问题进行深入细致地调查,对获得的材料进行认真分析研究,发现其本质特征和基本规律之后写成的书面报告。在英语书面表达训练中,我们经常会遇到这一类写作题,要求同学们根据调查结果,对某种现象进行分析、得出结论并谈谈自己的看法。2.确定人称:本文的主要人称为第三人称,兼用第一人称。3.确定时态:由于本文是调查报告,针对现在的事情,所以用一般现在时,但是调查已经完成,兼有过去时态。
二、谋篇布局调查报告通常包括以下三个方面:首先,弄清调查结果反映出的信息、问题或现象,对其做一些客观的介绍;其次,分析这些数据或事实反映出的问题,得出结论; 最后,通常在文章的最后一段阐述作者个人的看法和建议。
