Final answer:
The subjects of the sentences are 'Dancing' and 'Playing chess,' respectively, as they indicate the activities being described. To ensure clarity, it is essential that the information in a sentence supports the subject and verb agreement without interruptions.
Step-by-step explanation:
The subject of a sentence is the person, place, thing, or idea that is doing or being something. In the sentences provided:
- Dancing is the love of Tiffany's life? The subject is 'Dancing' because it is the activity that is being discussed as the love of Tiffany's life.
- Playing chess is Steve's secret passion! Here, the subject is 'Playing chess' as it is the activity described as Steve's secret passion.
To eliminate confusion in sentence structure, it's important that the subject and verb agree and that any additional information provided in the sentence supports and does not interrupt this agreement.
For instance, a mixed sentence like 'Learning to ballroom dance it has shown increased agility, and you live longer' has issues because 'it' disrupts the expected flow after the gerund phrase 'learning to ballroom dance,' leading to confusion. A better revision would be 'Ballroom dancing has been shown to increase agility and lengthen life,' providing clarity and a direct statement about the subject 'Ballroom dancing.'
