2 We use the verb to be (am / is / are) to make yes / no questions that don´t have an action verb. We make this type of question when we want to know about facts / reality.Are you married?Yes, I am.Is he your brother?No, he isn´t. = No, he is not.Is she an artist?Yes, she is.

4 Verb to be + Subject + complement?

6 When we have an action verb, we need a ¨helper¨ (an auxiliary verb) to form the question – DO/DOES Do you play soccer?Yes, I do.Do they speak French?No, they don´t. = No, they do not.Does she drive to work?Yes, she does.Does he travel a lot?No, he doesn´t. = No, he does not.
7 Remember that when forming a question with the 3rd person singular (he/she/it) we use DOES, and the action verb goes back to its base form:He travels every week. (the verb ¨to travel¨ is conjugated)Does he travel every week? (the verb travel is now in his base form – the infinitive without the ¨to¨)Let´s remember the conjugation of verbs in English:I travel study playYou travel study playhe/she/it travels studies playsWe travel study playYou travel study playThey travel study play
