    Do/Did : auxiliaire ou simple verbe ?





I. Le verbe "do"



Le verbe do est l'équivalent du verbe français "faire". Il est suivi d'un COD :

- I do my homework every evening. (= Je fais mes devoirs tous les soirs).
Sa forme passée, did, correspond aux différentes formes passées du verbe "faire" :
- I did my homework last night. (= J'ai fait mes devoirs hier soir).
Il se combine, au présent et au passé avec la forme be+ing1 :
- I'm busy. I'm doing my homework. (= Je suis occupé. Je fais / je suis en train de faire mes devoirs).
- I was doing my homework when Dad entered my room. (= Je faisais mes devoirs quand Papa est entré dans ma chambre).


II. Au passé, aux formes interrogatives et négatives



Comme tous les autres verbes, do est conjugué avec l'auxiliaire did qui, lui, n'est pas suivi d'un COD mais d'une base verbale.
