雅思阅读之说明文

　　Expository writing is a type of writing, the purpose of which is to inform, explain, describe, or define the author's subject to the reader. Expository text is meant to deposit information and is the most frequently used type of writing by students in colleges and universities. A well-written exposition remains focused on its topic and lists events in chronological order. Examples of this type of writing are cooking instructions, driving directions and instructions on performing a task. Key words such as first, after, next, then and last usually signal sequential writing. Second-person pronouns may be used in such writing, if needed; for example, in a how-to essay a writer may choose to personalize the instructions with "you." However, the use of first-person pronouns should be avoided. Expository essays will not reveal the opinion of the writer.

　　Exposition is a type of oral or written discourse that is used to explain, describe, give information or inform. The creator of an expository text can not assume that the reader or listener has prior knowledge or prior understanding of the topic that is being discussed. One important point to keep in mind for the author is to try to use words that clearly show what they are talking about rather than blatantly telling the reader what is being discussed. Since clarity requires strong organization, one of the most important mechanisms that can be used to improve our skills in exposition is to provide directions to improve the organization of the text.

　　Many schools, businesses and colleges use these to test their students/employees.
