Final answer:
Effective communication requires a variety of sentence patterns and proper punctuation such as commas, which clarify the meaning and relationship between ideas. Key elements include using commas in complex sentences and ensuring subject-verb agreement by identifying the true subject.
Step-by-step explanation:
The correct usage of sentence patterns is vital for conveying meaning and establishing the relationship between ideas effectively. By varying sentence structures, one can create a richer and more engaging narrative. When revising sentences to ensure clarity and precision, here are some examples:
- Adding a comma before the conjunction in complex sentences: 'I finally found my keys, and I got to work just in time.'
- Correcting comma splices by removing unnecessary commas: 'Mrs. Contreras threw out her old coffee table and cleaned the carpet.'
- Placing commas correctly to separate clauses: 'Taking the elevator to the roof, we hoped we could see the skyline and the bay.'
Additionally, when addressing subject-verb agreement, it's important to identify the true subject of the sentence to ensure the verb aligns properly, as in 'The play comes highly recommended.'
