Explications :
The Simple Past is the most used past tense in English. It is used to talk about a specific or habitual action in the past, and also in the unreal.
In the affirmative, it is formed by adding the ending 'ed' to the verb (if it is regular). For the verb 'work', this gives 'worked' to all people.
In the negative and the interrogative, the auxiliary 'did' appears, and the mark 'ed' disappears from the verb.
The perfect present tense is formed with the present perfect auxiliary have (she/he/it has - I/we/you have) and the past participle of the verb. Orally, one contracts has and have in 's and 've.
Note: Be careful not to confuse is and has in their contracted form: 's. Remember that has is necessarily followed by the past participle. Is can be followed by a verb in ing or the past participle, but only in the passive form.
She's accepted his decision. (has)
He's working on a new project. (is)
He's accused of lying. (is)
