Correcting Sentence Commas and Structure
It's essential to ensure that sentences accurately reflect what's being communicated with correct punctuation and structure. Commas help clarify meaning by separating elements within sentences, such as items on a list or clauses. Proper sentence structure ensures that sentences are both clear and grammatically correct. Let's examine and correct a few examples.
Taking the elevator to the roof, we hoped we could see the skyline and the bay.
I let my neighbor borrow my phone because she said hers was tapped by the police.
When revising for mixed-construction sentences, it's important to maintain coherence within the sentence. Here's a revised example:
People who have hobbies are happier than others.
A group of five students resolved the test quickly, accurately, and without any assistance. (Correct use of short-to-long principle)
Parents have not been attending the evening meetings because some work late, and others cannot come to school three nights in a row. (Correct sentence structure)
