The document provides guidance on writing effective body paragraphs in essays. It discusses that body paragraphs should be unified, coherent, systematically organized, and well-developed with sufficient support. Each body paragraph should introduce a new idea that elaborates on a major point in developing the overall argument. Body paragraphs are organized by introducing a topic sentence, followed by a supporting point and evidence/examples for that point. Cohesion and flow between paragraphs can be achieved through the use of transition words, pronoun references that connect ideas, and repetition of key ideas. The document also lists several methods for organizing body paragraphs such as chronological order, comparison/contrast, cause and effect, etc.
