Reading and writing are often closely related.  By reading a good example of writing, the reader can benefit themselves from an experienced writer's effective writing, and, in turn, improve their writing skills.  In addition, understanding the style of writing will also help the reader to take in information from the article, as well as to enhance their comprehension of the article.  Thus, in this unit, we will first focus on the style of comparison writing and learn topic-related vocabulary words and expressions.

In this unit, we will study the notion of collocation through activities to help you enhance both your speaking and writing.
