Answer:
One of my favorite places for recreation and exercise is the local park. The park is a tranquil oasis, filled with lush greenery and a variety of amenities. I often jog along the winding paths, taking in the fresh air and the beautiful scenery. The park also has a playground where I sometimes play basketball with friends.
In this paragraph, I used complete sentences to describe the park and my activities there. Each sentence has a subject and a predicate, making them complete. I also ensured that the sentences are related to the main topic, which is about a place I go for recreation or exercise. This helps to maintain coherence and unity in the paragraph. The paragraph is also within the specified length of 4-7 sentences.
