French language Q&A Forum

Can someone explain why the first verb in the extract is in the perfect, while the second (and subsequent) are in the imperfect? They all seem to be describing the continuing circumstances, which calls for the imperfect as I read this: Expressing opinions and describing with the imperfect tense in French (L'Imparfait)

the lesson says "Adjectives modified by adverbs with 2 or more syllables"
And the lesson made an example:
"Compare these examples with the following counter-example containing a one-syllable adverb:
un très joli manteau
a very pretty coat"

Based on the information the lesson provided, I assumed "une histoire très intéressante" wouldn't be right.
I saw other questions on this, but none really explained the rule.

Is it because besides having one-syllable adverb, the adjective also have to be one of those that are put before the verb?

Why is, ”ou s'il s'arrête brusquement” in third person singular instead of third person plural?

Merci

I'm returning to this lesson after being away from it awhile. And I have the same concern as before: The examples do not tie to the ones on the tests. Terribly confusing. Sometimes using "a", other times not. What gives? I can't be the only one rattled by this, Could someone please simplify this for me? Thanks.

Especially those with "que" followed by noun.
I can still wrap my mind around and understand "Qu'est-ce que c'est?", but "Qu'est-ce que c'est que un stylo", how are they connected with "que"? 

Forgive me if I wrote some sentence wrong, it's really kind of weird for me to remember 😂

Unlike the examples in the explanation materials, THE question /answer is incorrect.  The review materials limit the number of people to one actor and one actress (only two people). In the exam question, their is an unknown number of people (could be 100) therefore the person speaking is unknown.

I used the verb s'éveiller for "wake up", but it was not given as one of the alternatives.  I thought "se lever" meant "to get up (out of bed)", rather than specifically to wake up.  Can you clarify?

The quiz asked me to find correctly placed adjectives and I thought colors are supposed to go after the noun? Unless there is a exception here i missed.

When I wrote "à vélo" I received a correction that I should have written "en vélo." However, I was under the impression that both "en vélo" or "à vélo" are acceptable (see: À/en + [means of transportation] (French Prepositions)). Was this an error or is there a reason that "à vélo" is not acceptable here?
