首先,各位朋友在写作前应该了解英文短文的四大种载体(four kinds of writing)： 记叙文.描写文.说明文和议论文。 简单地说, narration 是讲述一个故事；description 是描写某人、某物；exposition 侧重于解释、说明某事物、某现象、某情况等；argumentation 的目的在于使人们信服自己的立场、观点。 例如：以下一组作文题，意味着可以分别写成四种载体的文章： 1. How I Got a Gift from My Parents 2. The Best Gift I Ever Got 3. How to Use the DC- a Gift from My Parents 4. Topic142. A gift (such as a camera, a soccer ball, or an animal) can contribute to a child’s development. What gift would you give to help a child develop? Why? Use reasons and specific examples to support your choice. 第一个可用记叙文来写。第二个可写成描写性文章。第三个当然用说明文最适宜。第四个也就是我从185篇里抽出的一道作文题，个人认为写为议论文形式较好。 综观很多TWE题目后，我们可以发现TWE毫无疑问适合以 exposition 或 argumentation 这两种载体操作。这里我就从个人角度适当分析一下。 一. 载体的穿插使用 每篇文章都必然归属于某一种载体，但同一篇文章中并不排斥其他载体的表达方式，只是有主次之分。 比如，记叙文在叙述一个故事的过程中，常常不可避免地穿插些描写；议论文也可有叙述、描写；说明文更离不开适当的描写甚至议论的配合。 以下我以TWE练笔中的一篇范文举例。 TWE练笔专贴◎第十期Topic15.Neighbors are the people who live near us. In your opinion, what are the qualities of a good neighbor? Use specific details and examples in your answer. 作者: llneaco Living in the neighborhood, we cannot avoid rubbing shoulders with people of all ages and all walks of life everyday. therefore, though not imperative, it is anyway preferable to have an inhabitant with agreeable qualities residing nearby. In terms of the qualities of a good neighbor, as I have observed, could be in the rough concluded as “law-consciousness”, “respectfulness” and “readiness to help”. 开头表明了作者的立场：we cannot avoid rubbing shoulders with people of all ages and all walks of life everyday. therefore, though not imperative, it is anyway preferable to have an inhabitant with agreeable qualities residing nearby. 随后说明了具体的三个方面：In terms of the qualities of a good neighbor, as I have observed, could be in the rough concluded as “law-consciousness”, “respectfulness” and “readiness to help”. 而后面的3个段落，围绕the qualities of a good neighbor这一中心，开展说明。 In the first place, a good neighbor should undoubtedly be well conscious about the law because no one is willing to get caught up in problems from someone else’s illegal activities. Even though I might not have committed any crime, I could still be involved since the one who committed it lives around the corner from my house. Still worse, I might feel quite insecure about my personal safety and property living in the vicinity with such a lawless person, which is like putting the cat near the goldfish bowl. In short, having a sound knowledge of law is the very prerequisite of being a good neighbor. “Respectfulness” is another trait of a nice neighbor. By “respectfulness” I indicate not only . 更多信息请关注100Test外语站点。
