- Jack and Sam walk in the park every day. (This is a simple present tense sentence that describes a habitual action. The subject is plural, so the verb does not have an -s ending.) - Do Jack and Sam walk in the park every day? (This is a yes-no question that uses the auxiliary verb do before the subject. The main verb walk does not have an -s ending or a to-infinitive.) - Jack and Sam are walking in the park now. (This is a present continuous tense sentence that describes an action happening at the moment of speaking. The subject is plural, so the verb be is in the form of are. The main verb walk has an -ing ending.)
