Describe the advantages and disadvantages of various sentence structures.

 By choosing words and sentence structure with care, you can create a rhythm that emphasizes important points, enlivens your writing style, and makes information more appealing to your reader. For example, a short sentence that highlights a conclusion at the end of a substantial paragraph of evidence makes your key message stand out. Try for a mixture of sentences that are short (up to 15 words or so), medium (15-25 words), and long (more than 25 words).
Each sentence length has its advantages. Short sentences can be processed quickly and are easier for nonnative speakers and translators to interpret. Medium-length sentences are useful for showing the relationships among ideas. Long sentences are often the best for conveying complex ideas, listing multiple related points, or summarizing or previewing information.
Of course, each sentence length also has disadvantages. Too many short sentences in a row can make your writing choppy. Medium sentences can lack the punch of short sentences and the informative power of longer sentences. Long sentences can be difficult to understand because they contain more information and usually have a more complicated structure. Because readers can absorb only a few words per glance, longer sentences are also more difficult to skim. By choosing the best sentence length for each communication need and remembering to mix sentence lengths for variety, you'll get your points across while keeping your messages lively and interesting.
