数据图表类作文
　本单元我们阅读关于数据在我们生活中起重要作用的文章，写作范文介绍世界人口，数据作文不仅是英语写作的一种形式，更是 训练学生们“处理信息、分析问题” 的综合能力。它以 “数据” 为桥梁，连接语言学习与逻辑思维的需求，帮助学习者在精准表达中构建理性思考的习惯。这类作文要注意以下事项：
一、文章开篇要点明图表主题、对象、时间及方式，快速引出数据内容。
二、文章中间段时数据描述与分析（核心部分）。分点呈现数据，对比差异，
突出主要趋势或现象。
三、文章结尾观点总结与延伸。基于数据发表看法，提出建议、原因或影响，
升华主题。
二、写作注意事项
（1）时态与语态：
调查背景用过去时；
数据描述可用一般现在时（客观结果）；
观点分析用一般现在时。
（2）数据表达多样化：
避免重复使用 “percent”，如：“40%” 可表述为 “nearly half” “four out of ten” “approximately 40 per cent”。
（3）逻辑连贯：
用连接词区分数据层次（如 Firstly... Secondly... Finally...）；
对比数据时用 “while /by comparison”
（4）避免主观臆断。
（5）语言简洁准确。

Doing housework
　Last week, our class made a survey on doing housework among ourselves. Here are the results.
According to the survey, 40 per cent of our classmates often do some washing such as washing clothes, dishes and vegetables. There are 35 per cent students cleaning the house. They sweep the floor and clean the window. 12 per cent students do some shopping for their families. And about 8 per cent of them do the cooking. However, there're 5 per cent students hardly doing any housework.
I think as a member of the family, it's our responsibility to do housework. We should learn to do some simple housework. Also, it's helpful for us to learn some living skills from it.
