在英语四级的备考强化阶段，掌握有效的举例论证技巧能够让你的文章更具说服力。其中，数据可视化的应用是一个非常实用的方法。
一、数据可视化的重要性
当我们想要表达观点时，单纯的文字描述有时候显得比较空洞。例如，在论述某种现象的普遍性或者趋势时，如果能结合数据并且以直观的方式进行呈现，就会让读者更容易理解和接受。就像我们要说明大学生使用手机的时间很长这个问题，如果只是说“很多大学生每天花大量时间在手机上”，这很难给人一个确切的概念。但要是我们说“根据调查，65%的大学生每天使用手机超过4个小时”，这样就把抽象的概念具体化了。这就是数据可视化的初步体现，把调查得到的数据转化为更直观的表达。
二、数据转化的具体方法
- 百分数与其他表述的转换
- 当遇到百分数时，可以转换为分数或者近似的比例表述。比如65%，我们可以说成nearly two - thirds（近三分之二）。这种转换能够让数据听起来更加自然流畅，同时也丰富了我们的表达方式。
- 再如40%，可以说成two - fifths或者近似表述为over a half（超过一半）。
- 具体数字与相对概念的结合
- 如果有数据表明某个城市的人口数量为500万，我们可以进一步说明这个数字相对于其他城市的规模，如“这个城市的人口数量为500万，是同级别城市人口平均数的1.5倍”。
