RULE: 6.2 Try to vary sentence lengths and constructions to keep the text interesting. A series of short sentences with the same construction is boring and irritating to read. Thus, you should try to vary the sentence lengths and constructions in descriptive writing. Use connecting words to join separate sentences instead of writing long sentences. This will result in two or more independent clauses instead of a long sentence. (Refer to Section 4 for data about connecting words.) Example: WRITE: Each engine has a CSD to operate the AC generator at a constant speed of 8000 rpm. Differences in engine rpm and generator load have no effect on this constant speed. The CSD is on the engine gearbox which operates the AC generator through a differential gear in the CSD. A hydraulic motor controls the differential input. The motor can increase or decrease the number of revolutions to keep the generator at approximately 8000 rpm. NOT: A CSD has been installed on each engine. The CSD provides a means of driving the AC generator. The CSD drives the AC generators at a constant speed of 8,000 rpm. This speed is independent of the engine rpm or generator load. The CSD is mounted on the engine gearbox. The AC generator is driven by the engine gearbox. It is driven via a differential gear in the CSD. The differential input is controlled by a hydraulic motor. The hydraulic motor can increase or decrease the number of revolutions to the engine drive rpm. This keeps the generator rpm at approximately 8000. |
