French language Q&A Forum

I’ve been looking for the main difference with avoir besoin de and avoir envie de and thought I got it when you say that avoir envie de is to feel/need to DO SOMETHING! 

But then the first question to answer is J’ai envie d’une nouvelle voiture and that blew it out the water. 

I am confused again! Why use one over the other in this simple context?

Thank you

This is a bit of an indirect question related to this lesson about "aprés avoir fait".

The sentence used in the quiz is: "Lucette changea les draps aprés avoir fait le lit." This got me wondering about "changea" and what verb form it is, why we wouldn't say "Lucette a changé les draps aprés avoir fait le lit." But on further reading I see that this is just the difference between a form used in conversation French (passé composé - which perhaps most learners come across first) vs written French (passé simple - which learners come across later..?)

My other question is whether the sentence should actually read: "Aprés avoir changé les draps, Lucette fis / a fait le let." You change the sheets before making the bed, right?

The video in the following lesson says that it has no relation to the present

Why "mais elle,elle veut ..." not" mais elle veut ..."

It doesn't appear possible to rewind this sound clip. For me personally , that makes it much less useful, as you have to replay the whole thing from the beginning.  ( I have tried Firefox and Microsoft edge, so I don't think it's the web browser).

Could we please have an interface that allows us to rewind the sound ? Thanks Paul.
