Final answer:
In an expository essay, one should choose a narrow topic, state a clear thesis, and divide the thesis into three analytically related parts. For example, if 'vacations' is the broad subject, one might write about 'The Impact of Ecotourism in Costa Rica' with a thesis structured around its environmental, conservation, and socio-economic benefits. The essay should include well-developed paragraphs with topic sentences that relate back to the main thesis.
Step-by-step explanation:
When preparing for writing an expository essay, selecting a specific, narrowed topic is crucial for a focused essay. For instance, if 'vacations' is chosen as the primary topic, 'The Impact of Ecotourism in Costa Rica' could serve as a limited topic. The thesis sentence would state your position on the topic, like 'Ecotourism in Costa Rica has significantly contributed to the conservation of natural resources and the improvement of local economies.' The three-part analytical thesis might be structured as follows: 'Ecotourism encourages sustainable travel practices, supports the protection of wildlife, and benefits the socioeconomic status of local communities.'
Based on this thesis, topic sentences for subsequent paragraphs might include: 'Sustainable travel practices established through ecotourism minimize environmental impact,' 'Wildlife protection efforts bolstered by ecotourism promote biodiversity,' and 'Ecotourism boosts local economies by providing jobs and supporting local businesses.' A paragraph developing the idea of sustainable travel would further explain this specific aspect and show how it relates back to the thesis statement, using examples and transitions to ensure a logical organization.
