* Inthe Simple Present and Simple Past tenses of the Active Voice, the auxiliaries are used only for emphasis, and for the formation of questions and negative statements. Auxiliaries are never used with the Simple Present or Simple Past of the verb to be.
** When used without the auxiliary, the third person singular of the Simple Present, in the Indicative Mood of the Active Voice, has the ending s.*** When used without the auxiliary, the Simple Past form of the verb is used. For regular verbs, and for many irregular verbs, the Simple Past has the same form as the past participle.
**** The other modal auxiliaries could, may, might, must, should and would form conjugations in the same way as will and shall.
