Je recherche l'accord de la genre et nombre de la participe passé surtout avec l'auxiliaire verbe avoir dans un autre mots le complément objet direct et indirect de l'auxiliaire verbe avoir à la participe passé 

why use "pourra" instead of "pourront"? I thought tout means every, all.

She went to France for vacations, she generally rents a house in the country. Then she goes to the village to buy some fruits and vegetables, and to talk with some neighbors. Then she passes by a beakey and she buys a  warm baguette and a croissant for breakfast. In the afternoon she takes a walk in the country to explore the region. Sometimes she likes to have a fruit tart and she invites a few friends over for a snack. These are very relaxing vacations.

Can you say:

Je suis allée à Paris ainsi que à Bordeaux. 

If the sentence  is "Elle finira en prison pour avoir tué son amant." ....why does the English translation say "She will end up in prison for killing her lover" and not 'She will end up in prison for having killed her lover"....?

I've seen the use of ne (without pas etc). I've seen it with the subjunctive but also I think in another context. What does this mean and when do you use it?
