In the sentence, 'my little brother' serves as the subject who is performing the action of watching the Super Bowl, a prominent American sporting and cultural event.
Step-by-step explanation:
The subject in the sentence "My little brother watched the Super Bowl" is "my little brother." Here, 'my little brother' is the person who is performing the action or being talked about in the sentence. The verb, or the action being performed, is 'watched,' and the object of this action is 'the Super Bowl,' which is a major American sporting event.
The Super Bowl is known for its significant place in American culture as it involves not just the sports competition, but also large-scale social gatherings, consumption of food and drinks, and a general celebration among people, making it a cultural phenomenon as much as a sporting event.
The subject of this sentence is 'My little brother'.
In this sentence, 'My little brother' is the subject because it is the noun phrase that performs the action of watching the Super Bowl.
For example, if we rephrase the sentence to a question, we get 'Who watched the Super Bowl?' and the answer is 'My little brother', which confirms that 'My little brother' is the subject.
