Without a verb (predicate), a sentence is not a sentence. They are the indicators of identity or action.
The only time a predicate is not used is for certain interjections, which are not sentences.
These include such comments as:
Ouch! -- Shh! -- Huh? -- Wow! -- You! (actually may be the sentence "It is you!")
A command is a sentence that often uses an understood subject (you), so the only part of the sentence is the verb. For example : Run! Get out of here.
the words describing an action(s) in sentences or statements
No, not all English sentences require an object. Some sentences can be complete with only a subject and a verb. Objects are only necessary in sentences that involve transitive verbs, where the action is done to someone or something.
Infinitives can be used as subjects of sentences, objects of verbs, complements of certain verbs, and in sentences to show purpose or intention.
The subject must agree in number with the verb.
Sentences don't modify verbs. Verbs are part of a sentence. A verb in a sentence can be modified by an adverb: verb = walk, adverb = always. I always walk to school. verb = ate adverb = quickly The dog ate his food quickly.
They are natural sentences reason why is because every sentence has a verb in it.
There are three primary auxiliary verbs in English: "be," "have," and "do." These auxiliary verbs help form different verb tenses, aspects, and moods in sentences.
Pay attention on subjects and verbs to identify simple sentences , you will then include subordinates and coordinates for compound sentences .

Intransitive verbs are verbs that do not have a direct object (something receiving the action of the verb).I sneezed fifteen times in a row.She lies around all day.Justin always arrives late.Sit down!I go to the store every day.Many verbs can be transitive and intransitive, but the verbs listed above are always intransitive.
