RULE: 6.5 Always start the paragraph with the topic sentence. The most important part of the paragraph is the first sentence. This must be the "topic sentence", which tells your reader what the paragraph is about. Reading the topic sentence allows your reader to relate the paragraph to other information he has just read. To help with this relation to other paragraphs, the first sentence should also contain a "keyword" (see the paragraphs that follow). Thus, by reading only the topic sentences, the reader should be able to understand the broad outline of your text. If the reader is looking for some specific information, the topic sentence should be able to help the reader decide which paragraph has the desired material. After the topic sentence, the remaining sentences must go on to develop the topic, to give additional facts, or to discuss particular aspects. Each sentence must add new information, and must connect this information logically to what was stated in previous sentences. Example: UFirst Version Instrument Landing System During approach to the runway, deviation pointers in the course indicators give commands to fly up or down and left or right. This information comes from the VHF transceivers, which are part of the Instrument Landing System. This helps the pilot during the landing approach. When the pilot responds to the commands, the aircraft can be flown over the runway centerline (localizer) and at a fixed angle (glideslope) to the runway threshold. The localizer signals are processed by the transceiver and ...... UImproved versionU (The numbers identify the sentences) Instrument Landing System (1) The Instrument Landing System in the aircraft shows data that helps the pilot during the approach to the runway. (2) This system shows the pilot the deviations from the "localizer" and the "glideslope" paths. (3) (The localizer path is in line with the centerline of the runway. (4) And the glideslope path is at a constant angle to the threshold of the runway). (5) During the approach to the runway, deviation pointers in the course indicators show the pilot in which direction the aircraft must go: - Left or right (for localizer) - Up or down (for glideslope) (6) This data about deviations from the localizer and glideslope paths comes from two VHF transceivers, which transmit these... Note that in the improved version the material is divided into two paragraphs: Paragraph 1 - "Data to help the pilot", and Paragraph 2 - "How this data is transmitted". In the improved version, the paragraphs start with the topic sentences which clearly state what is going to be discussed. The information is built up slowly, and is logically connected. |
