In the United States, cell phones are a very popular item.
What are all VERBS both "Action" and "Be."
I don't think I understand your question. Are you supposed to identify the verb in the sentence you typed?
English verbs fall into two categories, yes: action verbs and linking verbs (forms of "to be" and a few others).

To find all the verbs in a given sentence or passage, you can follow these steps:
1. Identify the verbs that show action: Action verbs indicate some form of physical or mental action. In this sentence, the action verbs would be "are" and "popular," as they describe the state of being or the level of popularity.
2. Identify the verbs that show a state of being (known as linking or be verbs): These verbs do not show a specific action but rather connect the subject of the sentence to a word or phrase that renames or describes it. In this sentence, the linking verb is "are," which links the subject "cell phones" with the adjective "popular."
By following these steps, you can identify all the action verbs and linking verbs in a sentence. In the case of the sentence, "In the United States, cell phones are a very popular item," the verbs are "are" (a linking verb) and "popular" (an action verb that denotes the state of being).
