1． 体裁：说明文，议论文  最近几年的四六级作文的体裁以说明文和议论文为主。说明文如：How to Succeed in a Job Interview （2000，12，四级）, How I Finance My College Education（2000，1 四级）, Practice Makes Perfect， Haste Makes Waste（97，1 六级）议论文如：Don't Hesitate to Say "NO"（99，1 四级和六级）, Can Money Buy Happiness（95，1 四级）, Is a Test of Spoken English Necessary？（2000，6 四级） Reading Selectively or Extensively? (99，6六级)，Do "Lucky Numbers" Really Bring Good Luck? (98,6 四级和六级)2．段落类型：比较/对比，列举，程序等 说明和议论文章所采用的文章扩展模式一般以比较/对照，举例、列举、因果、程序等者居多。如：Don't Hesitate to Say "NO", Reading Selectively or Extensively等很多四六级写作中都涉及到两种观点的对比，整体的段落类型为对照型。Practice Makes Perfect, Harmfulness of Fake Commodities等可采用因果行的段落结构模式，也可以采用举例说明的结构模式。Advantages of a Job Interview则应采用列举的段落扩展模式。3． 出题方式：提纲式写作，中文提纲，一般为三句或两句。如：99年1月份考题Directions: For this part, you are allowed thirty minutes to write a composition on the topic: Don't Hesitate to Say "NO". You should write at least 100 words and you should base your composition on the outline (given in Chinese) below.1. 别人请求帮助时，在什么情况下我们会说“不"。2. 为什么有些人在该说"不"的时候不说"不"。3. 该说"不"时不说"不"的坏处。再如：98年一月分考题Directions: For this part, you are allowed thirty minutes to write a composition on the topic: Harmfulness of Fake Commodities.
