Thematic Development Patterns of Thematic Development

Following the example of multiple theme Nevertheless, the alternative Was not simple textual Topical theme rheme

d. Interpersonal Theme

Interpersonal theme occurred before the topical theme. They may be Modal Adjuncts, vocatives, finite or Wh-elementsmood marking Gerot and Wignel, 1994 Below are examples : John,, we Want to meet you vocative Topical theme rheme

D. Thematic Development

The flow of information in a sentence from Theme to Rheme is crucial in achieving communicative effectiveness in a message. The exchange of information between Successive Rheme and Rheme pairings in a text is called Thematic Progression Eggins, 1994:303. Thematic progression contributes to the cohesive development of a text, that is to say, in cohesive text the distribution of given and new information needs to follow certain patterns. There are several main types of thematic development, which depends on different text types. For example, in a narrative-type text we often repeat Theme of one clause into Theme of subsequent clauses. For example: Theme Rheme A good teacher need show great passion to the teaching He or she should be intellectually and morally honest. He or she should have a genuine capacity to understand students However the Thematic development of an academic text is different. Fries 1983 made the point that the Thematic progression of an academic text needs to have high incidence of cross-referencial links from the Rheme of one clause to the Theme of the next clause, as the academic texts present complex arguments in which each successive ideas is an expansion of an idea in the previous sentence.

E. Patterns of Thematic Development

The development of Theme and Rheme gives significant contribution to make texts cohesive. Furthermore, Eggins1994:302 explains that Theme makes the cohesion and coherence of a text has to do with how Thematic elements separated each other. Eggins1994:303-305 also explains three main patterns of Thematic development. They are as follow: 1. Theme re-iteration: one basic way to keep to a text focused i.e. cohesive is simply to re-iterate an element. As we saw at lexical cohesion, repetition is an effective means of creating cohesion. A text in which the Theme never varied would not only be boring to read or listen to, but would indicate a text which is going nowhere. Thematic shifting can be achieved either “accidentally”, with the new Theme coming from outside the text, or cohesively, in which case we can describe it as Thematic progression. This pattern is diagramed as follow : Clause 1 Theme Rheme Clause 2 Theme Rheme Clause 3 Theme Rheme 2. The zig-zag pattern: in this pattern, an element which is introduced in the Rheme in clause 1 gets promoted to become the Theme of clause 2. this pattern is diagrammed as follow : Clause 1 Theme Rheme Clause 2 Theme Rheme Clause 3 Theme Rheme 3. The multiple-Theme pattern: in this pattern, the Theme of one clause introduces a number of different pieces of information, each of which is then picked up and made Theme in subsequent clauses. Clause 1 Theme Rheme a b c Clause 2 Theme Rheme Clause 3 Theme Rheme Clause 4 Theme Rheme So, it is not impossible that a cohesive text will draw on the zig-zag strategy and the multiple-Theme strategy. As, Eggins1994:305 states that written text will in general use Thematic progression strategy more frequently. Thus, both zig-zag and the multiple-Theme pattern will be common.
