托福寫作中有一種題目是要求考生來敘述自己觀點的，這種議論型托福作文題目很考察考生對于自己想法的解釋，有時候必要性的要配合一些權威型數據來幫助說明。那么下面的托福寫作經驗就介紹一下如何合理運用數據當作例證。
　　使用權威數據來證明我們的觀點，很多同學會有疑問，覺得自己沒有閱讀過很多的數據類文獻，覺得自己的數據太不真實，所以不敢往上寫。首先，給大家打消這個疑慮，這個權威數據真的需要我們自己去讀學術類的期刊嗎，不需要。我們只需要學會合理編寫數據，就可以了。同學們會問了，編的數據可靠嗎，考官會去驗證你數據的真實性嗎? 這個大家不要擔心，ETS的考官不會輕易懷疑大家所寫的數據，因為參加托?？荚嚨娜巳海形覀冞@樣的科研小白，也有各個學科的大牛，所以只要你編寫的數據合理，ETS是不敢妄下判斷否定你的托福寫作中論據的真實性的。
　　重點來到了，怎么去編寫數據例證呢?
　　托福寫作經驗介紹：首先我們要有模板，
　　模板一：
　　A 年份 survey/ report, conducted by 組織/機構/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 組織/機構， shows that …
　　其次，我們要積累編寫數據例證時常用的機構/組織的名稱：
　　環保局Environmental protection agency
　　衛生廳 department of public health
　　教育部Ministry of Education
　　人力資源部Human resource Department
　　交通局 Traffic department
　　數據類題目適用于哪類題目?最適用的題型是今昔對比類題目， 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：
　　托福作文題目大意： 20年后，人們會有更多休閑時間。
　　人們休閑時間越來越多可以通過調查人們在1995和2005工作時長的減少反映出來。
　　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 .
　　題目大意： 現在更難以去判斷一項工作是否成功。
　　通過一項問卷調查來說明現在人們打破了以前鐵飯碗的觀念，開始從事其他類別的工作，從而證明人們對于成功工作的定義變得多樣化。
　　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.
　　通過古今對比體面工作中女性比例的上升，來證明女性接受教育比以前要容易了。
　　總之，我們要想熟練的運用數據類論據，首先，記住固定的表達方式，其次，要總結常用的機構名稱，最后，要知道數據類論據適合古今對比類文章。
