To determine the subject, verb, and object in a sentence, it helps to identify the main action or idea being expressed. In this case, the main idea revolves around the concept of "preparation." The subject is "The best preparation," as it is the entity performing the action of preparing. The verb is "is," which is a linking verb that connects the subject to the complement, in this case, the infinitive phrase "to do good work today" serves as the object. The object complements the verb by providing further information about what is involved in the act of preparation.
