托福写作中，常见的写作手法有学生最熟悉的举例，即用一个具体的事例来论证想要表述的观点；除此之外，还有说理也是一种常见的写作手法，即用一些具体明确逻辑关系和语言来论证想要论述的观点。这两个写作手法的优势是具体详尽，且很有画面感，但是缺陷在于无法像数据一样明确得指出论点的要害，所以数据例证的写法在托福写作中已经成为了必不可少的论证方法。接下来我们来对其的具体写法作详细的论述。
模板一：
A 年份 survey/ report, conducted by 组织/机构/xxx university, (after polling xxx 人群 aged x and x) proved that xx% a, xx% b, xx% c.
模板二：
According to 年份 surveys, conducted by 组织/机构， shows that …
其次，我们要积累编写数据例证时常用的机构/组织的名称：
环保局Environmental protection agency
卫生厅 department of public health
教育部Ministry of Education
人力资源部Human resource Department
交通局 Traffic department
数据类题目适用于哪类题目?最适用的题型是今昔对比类题目，如下：
Twenty years from now on, people will have more leisure time than they do now.
Secondly, the working time of people has become much shorter, thus resulting in people's preference for more leisure time. According to 1995 and 2005 surveys conducted by Human Resources Department, people worked 8 hours every day in 2005 while people in 1995 worked almost 9 hours each day. The shortened work time is caused by the wide use fo machines.
分析：
题目大意： 20年后，人们会有更多休闲时间。
人们休闲时间越来越多可以通过调查人们在1995和2005工作时长的减少反映出来。
It was easier to identify what jobs or careers were secure and successful in the past than it is now.
Additionally, a questionnaire about choosing an ideal job conducted by Career Service Center in China has surveyed two groups of people with the first at the age of 50 and above and the second aged from 20 to 30. 58.4%. According to the above survey, 32.5% of the first group respectively choose the option of civil servants and teachers. On the contrary, 72.4% of the second group circled the third option of other occupations such as singers, freelance writers and so on. The difference in the two groups of figures lies in the transition of people's attitude of choosing a job .
题目大意：现在更难以去判断一项工作是否成功。
通过一项问卷调查来说明现在人们打破了以前铁饭碗的观念，开始从事其他类别的工作，从而证明人们对于成功工作的定义变得多样化。
Nowadays it is easier to get educated than in the past.
A 2012-report conducted by Beijing Human Resources Department: the female percentage in the occupations such as professors, doctors, layers. Engineers grew by 80.3% compared to the days 50 years ago.
