A subject is usually a noun or a pronoun, but it may also be a gerund, an infinitive, a clause, or a phrase.
The verbs in these patterns are action verbs or linking verbs.
It’s important to consider that subjects or verbs are sometimes compound. That means there is more than one word serving as a subject or a verb in a sentence or question.
It’s useful to identify prepositional phrases before you decide which word is the subject, the verb, the direct object, etc. Many teachers tell students to draw parentheses around the prepositional phrases–if they exist–before determining the pattern of the sentence.
In the first sentence, the subject is "Bob" and the verb is "works."
In the second sentence, the subject is "there," the verb is "is" and the subject complement is "table."
In the third sentence, the subject is "most," the verb is "like" and the word "class" is the direct object.
It’s easier to identify these parts of the sentence if you find the prepositional phrases first.
