第一段可用事实开始，用有人发音好，有人发音差的现象引出问题：为什么会这样?第二段分析原因。可用列举法，分别指出母语的影响、学习者的态度、是否常与说母语的人接触以及学习者本身的条件等都会对发音产生影响；第三段指出改进措施，虽然母语的影响和学习者本身的条件不好改变，但其它两方面却可以改变，结束全篇。
[范文]
Some students are very good at learning English pronunciation. They speak the language beautifully. Other students, however, find it difficult to learn accurate English pronunciation. What, then makes the difference? There are, in my opinion, four reasons that account for the difference. First, and perhaps the most significant, was the mother tongue. The closer the student＇s own language is to English to start, the greater the chance of achievement. Secondly, the Learner＇s attitude to pronunciation makes the difference. Students who believe in the importance of pronunciation tend to make more progress. Thirdly, contacting with native speakers of the language has strong positive effects on pronunciation. Fourthly, and possibly the least important, was the student＇s own natural ability. Agoodear and the ability to imitate help, but are far less significant than the other three factors. We can＇t change the first factor–the mother tongue–but we can control the second and the third. Therefore we can have considerable influence over our own progress with pronunciation.
