The two tenses that will never have auxiliary verbs are the simple present tense and the simple past tense. In these tenses, the main verb stands alone without the need for an auxiliary (helping) verb to form the sentence. For example, in the simple present tense, "I eat" and in the simple past tense, "She ran," the main verbs "eat" and "ran" do not require auxiliary verbs to convey the intended meaning.
