Here's how paragraphs work:
1. Topic Sentence: The paragraph begins with a topic sentence that states the main idea clearly and concisely.
2. Supporting Sentences: Following the topic sentence, you have supporting sentences that expand on the main idea. They provide details, examples, explanations, or evidence to illustrate and support the topic sentence.
3. Unity: All the sentences in a paragraph must relate to the same main idea. They should work together to develop and clarify the topic sentence.
4. Coherence: The sentences within the paragraph should flow smoothly from one to the next, creating a logical connection. This is achieved through the use of transition words, sentence structure, and consistent verb tense.
Example:
Topic Sentence: The Great Barrier Reef is facing serious threats.
Supporting Sentences: Climate change is causing ocean temperatures to rise, which leads to coral bleaching and death. Pollution from coastal development and agriculture is also harming the reef. Overfishing and destructive fishing practices are further depleting the reef's ecosystem.
In this example:
* The topic sentence clearly states the main idea: the Great Barrier Reef is in danger.
* The supporting sentences provide specific examples of the threats facing the reef.
* All sentences relate to the same main idea, contributing to the paragraph's unity.
* The sentences flow smoothly, using transition words like "which" and "also" to create coherence.
By following these principles, you can write clear and effective paragraphs that effectively communicate your ideas.
