不同的essay，文章长度、风格、内容有不同，但是一般不外乎包括如下元素：
- 文章标题(Title：gives a hint about the essay’s topic)
- 导入语 (Introductory paragraph：introduces the essay’s topic and contains the thesis statement)
- 中心句 (Thesis statement：contains the essay’s topic and its controlling idea)
- 主体段落 (Body paragraphs：each has a topic sentence and contains details that support the thesis statement)
- 总结语(Concluding paragraph：brings the essay to a satisfactory close)
一篇essay合格、理想的结构布局如下所示，经典五段式。主题句通常分解为三个子主题;相应地，主体段落分为三个段落，每个段落集中阐述一个子主题。
