本段采用了三个事例来说明主题句中的关键词组different forms of exercises，这三个例子分别由连接词for example, for another example 和 besides引出，最后由引导的结尾句总结全段内容。
举例法中常用的连接词有：for example (instance), one example is, besides, furthermore, moreover, in addition等。
3. 叙述法(narration)
叙述法发展段落主要是按照事物本身的时间或空间的排列顺序，通过对一些特有过渡连接词的使用，有层次分步骤地表达主题句的一种写作手段。用这种方法展开段落，作者能够清楚连贯地交待事物的本末，从而可以使读者可以清晰、完整地理解文章的含义，例如：
In the flat opposite, a woman heard the noise outside. When she looked out through the window, she discovered that her neighbor was threatened by someone. She immediately called the police station. In answer to the call, a patrol police car arrived at the scene of the crime quickly. Three policemen went inside the flat at once, and others guarded outside the building to prevent anyone from escaping.
这段是按照事物发展的先后顺序，叙述从发现案情、报警、到警察赶到、包围现场的过程。全文脉络清晰，叙述的层次感强，结构紧凑。
常用于叙述法中的过渡连接词有：first, an the beginning, to start with, after that, later, then, afterwards, in the end, finally等。
4． 对比法或比较法(comparison & contrast)
将同类的事物按照某种特定的规则进行比较分析是一种常用的思维方法。通过对比，更容易阐述所述对象之间的异同和优缺点，例如：
The heart of an electronic computer lies in its vacuum tubes, or transistors. Its electronic circuits work a thousand times faster than the nicer cells in the human brain. A problem that might take a human being a long time to solve can be solved by a computer in one minute.
在这段文字上， 作者为了突出电子计算机运行速度之快，首先将它与人脑进行了比较， "-- a thousand times faster than --" ;而后，又将这一概念具体到了 "a problem"上，通过对比使读者从 "-- a long time -- in one minute"上有更加直观的认识。
常用于对本法或比较法上的过渡连接词有：than, compared with等。
5． 分类法(classification)
在阐述某一概念的段落中，常用分类法。通过对概念中所包括的事物进行分门别类，分别加以叙述，使读者有更为清晰的认识，如：
