French language Q&A Forum

I'm perplexed. My answer to a quiz was marked wrong when I translated "by tonight" as "d'ici soir". Apparently it should be d'ici ce soir. But by tomorrow is "d'ici demain". Could you please explain the difference because the lesson doesn't address this. Thanks.

Nous nous intéressons au sport. Nous nous yintéressons 

How would you say this in first person singular?

Je m’intéresse au sport. Je m’y intéresse. Is this correct?

Why "a bu dans ma gourde"?  Drank in my flask?  Why not "a bu de ma gourde"?

Why can't i use ensuite instead of puis in this sentence?

"puis fera une escale à Paris avant de prendre un autre vol pour Montpellier. "

For "they always made me feel" the answer is "ils m'ont toujours fait" which is passé composé.  Seems to me this is a continuous action in the past so it should be the imparfait "ils me toujours faisaient." 

I notice all the examples in this section refer to "ne pas". Can other negatives like rien and jamais be used?

Pourquoi c'est permis pour "ce" être à place de "Elles" à la première phrase?

'qu'il m'a donnée pour mon treizième anniversaire.' - the link you provide with this question, 'special cases of past participle agreement with avoir' describes that, in passé composé with avoir, the past participle must agree with the object when the verb is preceded by a direct object, but also explicitly states that the rule does not apply to indirect objects. Is not 'me' in this case an indirect object (he gave it to me)?

The hint that is given first has cinque with lowercase, but when I used that I got it wrong. 

Could anybody help me with the form of the word: 'cochant'?

I have learned third person plural conjugation is cochent, but this word 'cochant' I couldn't find in a dictionary. 

As you know, cocher is infinitive form of verb but what about cochant? Please!

The original context: "Répondez aux questions en cochant la ou less bonne response."

Please help me!
