Answer:
The subject of the sentence is Ira.
The predicate is the rest of the sentence: loves to read books in summer.
Explanation:
When it comes to the English grammar, subject is what the sentence is about or who/what performs an action. In the sentence we are studying here, Ira is the subject since he performs the action of loving to read books in the summer.
A predicate is a structure that tells us something about the subject, what it is or what it does. In other words, the predicate of a sentence is everything else that is not a subject. In the sentence we are studying here, the predicate giving us information about the subject Ira is: loves to read books in summer.
