II paragraph

2.1. Paragraph structure

Most of the science and technology writing consists of paragraphs. A paragraph is a small unit of writing that focuses on one idea which is then further developed and explained. The three, most common parts of a para­graph are: topic sentence, supporting sentences, and a closing one (A.O. Strauch 1998).

The topic sentence

The topic sentence is most usually the first sentence in a paragraph. It introduces the main idea, the topic, of the paragraph. It has two constitu­ent parts: the main and the controlling idea. The main idea indicates the theme of the paragraph, but it is the controlling idea that identifies the angle from which it will be approached or what arguments will be presented.

This is the crucial part of a paragraph as it has to be at once clear and precise. Depending on the paragraph, the topic sentence can be a definition, it can present author's beliefs, viewpoints, etc. But, generally speaking, it has to be a kind of summary of what is to come in the paragraph.

A good example of a topic sentence is: Today's computers have four major components. The main idea of this topic sentence is today's com­puters. The controlling one is the fact that there are four major components. Thus, the readers would know that the paragraph would proceed to explain what those are and defend that viewpoint by supportive arguments. A bad example of a topic sentence is: Computers are important. This sentence is too broad and vague and so it would be too difficult to develop it adequately in one paragraph.

Supporting sentences

The supporting part of a paragraph explains, describes, or develops the main idea given in the topic sentence. Supporting sentences should pre­sent facts, details, and examples that directly relate to the main idea. They should be such as to concretely support the controlling idea of the topic sentence.

A closing sentence

A closing sentence summarises the idea expressed in the paragraph by simply restating it. It can also give a hint of what is to come in the next paragraph by opening another aspect of the theme discussed.

EXAMPLE:

Every instrument, no matter how sophisticated its application, or how complicated its design may be, contains at least one sensing element, a sensor. That sensing element is the heart of the device and is always a sur­prisingly simple electronic component. The basic purpose of a sensor is to convert (or transduce) differences in some environmental condition into a change in a circuit parameter (voltage, current, resistance, capacitance, in­ductance, etc.) that can be processed to achieve some desired result.

2.2. Kinds of paragraphs

According to the content, paragraphs can be classified as following:

definition, classification, description, compare and contrast, sequence, choice, explanation, and evaluation paragraphs (L.Hamp-Lyons 1987). This, however, is not the only possible classification. The classes may differ ac­cording to various criteria employed.

Definition paragraph deals with precise defining of a concept. Definitions can usually be given in two ways: either by identifying the class to which the term belongs and then stating the specific features and the main differences between the term and the other members of the class; or by us­ing words such as: (can) be defined as, be called, be termed, be known as, be referred to as, be used to, have/display/exhibit the capacity to/ the prop­erty of.

Type 1: A turbine is a machine which produces power when steam, gas or water is passed over the blades attached to the rotating drive output shaft.

Type 2: Turbine is defined as a machine which produces power when steam, gas, or water is passed over the blades attached to the rotating drive output shaft.

When writing a classification paragraph things or ideas are classi­fied into certain categories having some common feature and according to a clearly stated criterion. Useful expressions are: is a kind of, to be divided into, is a type of, falls under the category of, belongs to, is a part of, fits into, is grouped with, is related to, is associated with.

Example: ABS falls under the category of thermoplastics because it softens when heated again and again.

Classification can be made either from general to specific or vice versa.

Description paragraph is about what something is like. If it deals with certain properties, then it usually is about size, colour, shape, purpose. In case of measurement, the qualities to be mentioned are, for example: height, width, length, mass/weight, speed. It can also be about an analogy with something else. Then, these expressions would be used: is like, resem­bles... Location can be easily described with prepositions or adverbs of place, such as: sideways, below, beyond, inside, within, etc.

Compare and contrast paragraph explores similarities and differ­ences between or among certain things or issues. Some comparison and contrast expressions are:

Similarity: is similar to, both, either or, neither nor, also, too, as well.

Differences: on the other hand, however, but, in contrast (to), differs from, unlike, whereas, while.

Sequence paragraph describes a series of events or a process in some sort of an order. Usually, this order is based on time. For this purpose sequence markers are used. They are: first, second, third, in the beginning, before, then, after, finally, at last, subsequently, recently, previously, after­wards.

In a choice paragraph the author makes a choice, chooses which object, idea, or action they prefer. Often, an opinion is given on a choice of actions or events.

The following are the helper words for point of view and personal opinion: in my opinion, it is my belief, idea, according to my understanding, I think that, I consider, I believe, it seems to me, I prefer, like, dislike, hope, feel.

Explanation paragraph deals with reasons of how or why some­thing happens, it investigates into the causes and effects of certain events. The helper words are:

Cause: because, since, as a result, due to.

Effect: therefore, thus, consequently, hence, it follows that, if ... then.

Evaluation paragraph presents judgements about certain issues. The actual evaluation needs to be based on well defined criteria. It is often followed by recommendation also supported by referring to the stated crite­ria. The useful words are:

Criteria and evaluation: good/bad, consistent/inconsistent/, effective/non-effective, important, trivial;

Recommendation: suggest, recommend, argue for/against, advise.
