Let's start by understanding what the subject of a sentence is. In English, the subject tells us who or what the sentence is about or who/what is performing the action.
Part A: Identifying the Subject
Diego is good at math.
The subject here is "Diego" because he is the person the sentence is about. He is the one who is good at math.
The dog barks loudly.
In this sentence, "The dog" is the subject as it is the dog that is doing the action, which is barking.
Jennie has a bike.
The subject is "Jennie" because she is the one who owns the bike and is the focus of the sentence.
Part B: Completing the Sentences with a Subject
The ______ is red.
Example Answer: The "apple" is red.
In this example, "apple" is the subject as it is the item being described as red.
The ______ go to school.
Example Answer: The "children" go to school.
Here, "children" is the subject because they are the ones performing the action of going to school.
These exercises help you identify and create subjects in sentences, which is a fundamental skill in English grammar.
