French language Q&A Forum

I want to understand the word order of a demonstrative pronoun AS AN OBJECT (whether or not it is contracted to ça).  It was asked below, "Je l'adore" vs. "J'adore ça" but the point was missed in the answer.  when ÇA is used as an object, it seems to follow the verb, but when le, la, or lui is used, the object pronoun preceeds the verb. 
I've searched Lawless French and googled for this, but have not found anything that specifically addresses this nuance of word order. Please help!

"Quand elle aura des enfants, elle changera d'avis."

Usually we use 'changer de + noun' as a rule. So if I say '"...elle changera de son avis."  Why is that incorrect? ....to say... "...she will change her opinion/mind."

I love the twist at the end, I thought she was the student ha ha ha ;)

Why do you use “je chantais” instead of “j’ai chanté” after “Hier, en allant au travail? You mention that this happened yesterday, so it is a completed action in the past. 

The recommended translation of 'you are an animal lover and a camping enthusiast' is 'Vous êtes un amoureux des bêtes et un passionné de camping'. Is it possible to explain why 'bêtes' is preceded by a definite article and 'camping' isn't?

does it mean "but it didn't depend on my fabulous boyfriend?" it just sounds a little weird...

I see that some verbs that take de or à and the infinitive drop the preposition when an object follows the verb.  As an example, choisir de drops the preposition when referring to an object as follows:

Je choisis de partir

Je choisis la cérise

As opposed to rêver that keeps its preposition in both cases:

Je rêve de partir

Je rêve du paradis

Is there a rule for this?

Never sure about this one. I use ‘sortir’ when I’m leaving a house, for instance, but how does one ‘go out of’ a town? Seems to me that the examples using ‘partir’ and ‘quitter’ are the only correct ones, depending on context.
