A sentence with a compound predicate may have a single subject. To understand the concept of a compound predicate, we first need to understand what a predicate is. In grammar, a predicate is the part of a sentence that contains the verb and describes the action or state of the subject.

In a simple sentence, there is usually only one predicate that relates to the subject. For example, in the sentence "He is reading a book," the predicate is "is reading a book," which describes the action of the subject "he."

However, in a sentence with a compound predicate, there are two or more predicates that share the same subject. These predicates can be connected by coordinating conjunctions such as "and," "but," or "or." For example, in the sentence "She loves to sing and dance," the compound predicate is "loves to sing and dance," with the subject "she" being shared by both actions.

So, to create a sentence with a compound predicate while having a single subject, you can combine two or more actions or states connected by coordinating conjunctions.
