“举例法”是较为常见的例证方法，它可以是由一个词、一个句子或者几个句子组成。譬如Modern homes often include the comforts of modern life, e.g. Air-conditioning and modern kitchens.
常用的举例方法有多例法和单例法。首先看多例法，写这个方面的前提是对于一个话题有很多话说。譬如讲农业科技的发展使得食物更加有营养。首先现代科技在种子培养的发展方面使得农作物产量更高，富含营养更丰富，而且市场上水果及农产品也更多样化了。其次，人们可以将农作物种在温室里，可以将植物种植在具有适宜营养物质的人造土壤里，而不需使用各种化学药品加速作物生长。同时，食品加工也更先进了，比如米的加工，一些工序可以快速去除其中的杂质，同时能有效地将关键营养物质保留。在写的时候注意用恰当的连词将例子连贯就好了。
另外一种便是单例法。一个较长的、完整的举例应该包括“三要素”——举例引导句、例子本身、例子的含义。其中，例子本身和例子的含义不能被省略。
譬如降到现在人们吃的食物更健康了因为每个人都更重视均衡饮食了。举一个熟知的人的例子。The food we have is more healthful than before because individuals attach greater importance to a balanced diet.摆明观点Take for example my grandmother who is 65 years old and enjoys her current late-life.引出例子To keep a good figure and a sound physical condition, she focuses on the daily nutrition taken from the food. At breakfast, she generallyhas soymilk, cereals, a boiled egg, and a small sum of noodlesto keep energetic in the morning. At noon, she will have some meat such as beef and chicken to gain necessary animal proteins. However, in the evening,she only has some piecesof boiled lettuce or broccoli to ease the burden of digestion. Plus,the greasy, salty and very spicy dishes would barely exist in her personalmenu. Actually, countless are people who have a similar dietary habit as my grandmother’s.例子本身的细节The example highly illustrates that the food with low calorie, fat and cholesterol is increasingly popular among the modern people.最后点题，说明例子的意义。
在运用例子时，例子的表达要注意具体性，加入更多充满画面感的细节描写，可以让所说的东西更“可信”。
