To understand the use of the adjective clauses
To identify a text organization of classification

3. 1. Definitions and Exemplifications
The purpose of a paragraph of definition is to define, explain, or clarify the meaning of something. Because of the nature of definition, it may involve analysis, comparison and contrast.
A paragraph of definition provides the meaning or an example of a term or concept. Paragraphs of definition often begin with a single-sentence dictionary definition as a topic sentence and then go on to provide further explanation or examples.

7. Sample Paragraph
In capitals such as Brasilia, monumental modern structures determine the appearance of the city. Such buildings, however, are not the only structures created by architects. They also create buildings that are used by all of us in our everyday lives. Houses, stores, shopping malls, schools, and factories, for example, are usually built according to an architect’s instructions.

8. Grammar points: Adjective Clauses
A clause is a group of words containing a subject and a verb.
An independent clause is a complete sentence. It contains the main subject and verb of a sentence.
A dependent clause is not a complete sentence. It must be connected to an independent clause.
An adjective clause is a dependent clause, which modifies a noun. It describes, identifies, or gives further information about a noun. (It is also called a relative clause)‏

9. The pattern of Adjective Clauses
1. Using Subject Pronouns: WHO, WHICH, THAT
2. Using Object Pronouns: WHOM, WHICH, THAT
3. Using WHOSE (possession)‏
4. Using WHERE
5. Using WHEN
6. Using EXPRESSIONS of QUANTITY

10. Sample paragraph
Parasitology may be defined as the branch of biology, which deals with the nature of parasitism and its effects on both the parasite and the host. Broadly defined, a parasite is an organism, which lives for all or part of its life on or in another organism from which it derives some benefits, such as food, shelter or protection.

11. 3. Classifications
Classification means the grouping of items to show relationship between them. Items that are classified together have something in common; that is something must apply to all the items in that group or category. Therefore, paragraphs that divide people, places, or things into categories are called paragraph of classification.

12. signal words used in classification:
X consists of ……..
to classify
to sub-classify
to categorize
to sub-categorize
fall into
X may be classified according to ………

may be sub-divided into ……..
