Hi I don't understand why "Tous les enfants partent mais aucun ne prend le train"  is correct but 

:Tous les enfants partent mais aucun d’entre eux ne prend le train" is not.   

THE LESSON SAYS: We can also express none of them using aucun d'entre eux ne ... / aucune d'entre elles ne ..., I understand "aucun d’entre eux/elles" is used with people and les enfants are people. Thanks.

If would have + movement verb uses Être, would this apply to should have and could have versions of the same sentence? Or do they continue to use avoir + dû/pu ?  

Im just a bit confused since, i am trying to learn french and on the 7th or 8th question, it said hand sanitizer is gel hydracoolique, but ive never heard such a word! I dont know, im just a bit confused since, for new people at french, this word (i dont think) shouldn't be used, since i am getting better and better each day, but again, ive never heard this word, nor seen it, for that matter. I dont want to be a pain, but i think this shouldn't be used.

Entres - y

Is the negative n'y entre pas or n'y entres pas .... Does the s drop or not ?

What does this sentence mean, "Elle a posé toutes ses lettres au tour d'après"?

There is a sentence in the text:
" les odeurs de cannelle et d'épices évoquent des souvenirs d'enfance"

I seem to get this wrong quite often - why is there no article after de in all of these cases (de cannelle, d'epices and d'enfance).

Thank you!

How do you remember which countries/regions are masculine/feminine? I find this hard.
