I know that depuis can be used with the passé composé in the negative sentence but can it also be used with the affirmative?

How would you translate a sentence like:

I have seen him once since last week or They have visited their grandmother twice since last week. 

When I translated them into Google and other translation sites they both use the affirmative passé composé with depuis, which I didn't think you were meant to do. 

It may not have caught on generally, but I have seen the revised spelling of 'ognon' in use in supermarkets. Should be accepted as correct spelling, as well as the 'traditional' oignon (1990 rectifications).

Is un repas an acceptable alternative to un dîner ?

Also chez nous instead of à la maison.

Coucou!

I dont understand the recorded pronunciation in this phrase : Les plantes produisent l’oxygène. Why is the “ent” silent in produisent?  And why is the “l” silent in l’oxygène?

Merci pour votre aide 

Your pronunciation of Saoul sounds to me like soo in English, with no "a" sound.

Merci beaucoup. Ce texte est très intéressant! Merci d’avoir partagé.

In the last sentence, "nous nous écrions : "Bonne Année !", why is the verb reflexive, or, why is the second nous, needed?

Could you have 'ça' in this sentence as an alternative to 'ce' ?
