D. The Concluding Sentence

(Notes by Huifang Peng)
1. Usually the last sentence in a stand-alone paragraph, the concluding sentence often wraps up the whole paragraph by restating words or ideas from the topic sentence or summarizing the main points from the body sentences in a different way.  
2. Concluding sentences usually (not must) start with a transition, such as all in all, in all, in closing, in conclusion, in summary, and in short, that signals the end of the paragraph.
3. Nevertheless, writers may end their paragraphs differently for different rhetorical genres. For example, some writers may end a narrative paragraph by expressing a final opinion about what happened; and the transition they use to signal the end of the paragraph are likely to be prepositional phases of time such as in the end, or after the experience. For descriptive paragraphs, some writers may end one by giving a strong personal observation or impression about the topic. As for expository paragraphs, in addition to restating the topic sentence or summarizing the main points in the body of the paragraph, some writers may also offer a suggestion, add a final comment, make a prediction, etc. for different rhetorical purposes.
