在雅思考试中，大作文的写作取得高分的标准之一就是有理有据，所谓有理有据就是道理讲的清楚，例子用的合适。下面就让我们跟随张涛老师，一起探讨一下举证的方法和技巧。
一、摆事实
摆事实是指在行文当中描述一些自己或者熟知的亲友的经历。这样做的主要目的是用一些细节向考官展示我们对语言的驾驭能力，同时，通过真人真事引起考官的共鸣。例如：
First, ads disturb our life. Surely, we all have the experience that an insert of the information about a product often interrupts our pleasure of watching an exciting film on T.V, which makes us so annoyed that sometimes we have the impulse to call the T.V station to make a complaint.
What’s more annoying is that you have spent money on a newspaper, but you’ll find that most of the space in the newspaper is occupied by all kinds of disgusting ads about a medicine of dealing with sexual diseases, which has totally violated your previous desire of getting the news about what is happening.
二、列数字
实际上，大家看原汁原味的英文文章会发现很多作者会列举一些调查和研究成果来证明自己的观点，因为这样比较符合欧美国家人的习惯，在可信度上和摆事实具有异曲同工之妙。比如：
Ad is an effect way to develop economy. As is calculated by the Statistic Bureau of China, 80% of the products in China are promoted and marketed by ads, which has brought almost 20 billion incomes as the tax to the country.
Meanwhile, with the prosperity of ads industry, more job vacancies are created and more revenue is added to the GDP of China.
三、做引用
引用这个词，我们并不陌生，因为我们中国学生最擅长的就是引经据典，但是事实上，雅思考试当中，我们一般不引用名人名言，除非我们引用的是一个领域里面最顶尖的权威，是众所周知的人，比如孔子、亚里士多德、柏拉图等人的名言；或者经过证实了的，为大多数人认为是公理的名言，以及见诸于报纸和电视上的报道等，例如：
In recent time, more and more cases have been reported in newspaper and TV programs about the surprisingly increasing rate of children’s crimes. The situation has become so serious that it has aroused great concern of the whole community。
