Discourse

A discourse organizer is what motivates the author to write about the text. It will depend upon the hierarchy of the ideas or pieces of information presented by the author.
For some authors, the discourse organizer constitutes the point of departure to search for the author`s implicit intention.

Control argument/theme

To construct a theme, you need to use some strategies argument as:

• Identify the communicative function of the text 
• Infer the discourse organizer
• Decide the general specific argument of the whole text from the specific argumenr of the whole text from the specific arguments of every paragraph.

Specific arguments/strategies

• Argument: It has to do with the author`s intention in a paragraph, it is reason and it is beyond what is merely and explicitly said.
• Strategies:
• Elimination: It is a technique to get a specific argument in a paragraph. By applying this technique, you can omit unnecessary and irrelevant information to get to the essence of a text.
• Substituion: It is a technique that allows you to to paraphrase and reformulate a specific argument suggested in every paragraph. This technique as well as the elimination one is also used when getting the overall argument or central theme.
• Key words: It is a technique used to concentrate on the most important information in a text, given through the form of content words or linguistic words that convey meaning. By adopting this technique, you necessarily obtain the specific argument and it also contribuites to get central theme or argument of the whole text
