Bonjour ,
Je n'ai pas bien compris la diference entre le preterit et le present perfect ..et j'ai cet exercice à faire mais je ne sais pas si mes réponses sont corrects , pouvez vous m'aider ?

Puts the verbs between brackets in the preterite or the present perfect .

Philip (stare) stared speechlessly at number 9, Hellebore Close . The Queen (try) tryed to get the key into the keyhole .She asked "Charles , darling , (you+ever+use ) you has ever used that sort of key ?".William and Harry (laugh) laughed when Charles , unable to unlock the front door , (boot) booted it furiously .The door finally (open) has opened "I (never+see) have never seen such a mess !" said Charles , "This house (not+be) wasn't lived in for years !"
"Good Lord ," said the Queen , "I (never+do) have never done any housework in my whole life ..this is dreadful !".She (start) has started to cry .

voila...merci d'avance ..=)
