Here's what a good conclusion sentence should do:
* Restate the main idea: It should clearly and concisely summarize the central argument or point of the text.
* Provide closure: It should signal to the reader that the discussion is over and leave them with a sense of finality.
* Offer a final thought: It can offer a reflection, a call to action, or a broader perspective related to the topic.
* Avoid introducing new information: It should only summarize what has already been discussed, not introduce new ideas.
Example:
Paragraph:
"The importance of exercise cannot be overstated. Regular physical activity has numerous benefits for both physical and mental health. It strengthens the heart and lungs, reduces the risk of chronic diseases, and improves mood and cognitive function. Moreover, exercise can be a fun and enjoyable way to connect with others and relieve stress."
Conclusion Sentence:
"In conclusion, incorporating regular exercise into one's lifestyle is essential for maintaining a healthy body and mind."
Note: The conclusion sentence can also be used as a transition to a new topic or idea.
