Aurélie, so let me get this straight. For 'faire' to be correct in English as far as the quizzes go, I must use the word 'will' right?

Question

After lunch, the girls will do their homework, after lunch the girls are going to do their homework mean the same thing in English really. This just adds confusion!!! I am so frustrated with B1 and I have just began!! And the BOT takes too much time!!

Answer

Well, even in English there's a slight difference between "are going to" and "will do their homework". In fact, the difference is very similar to the French future proche and future simple. The difference is that future proche is mostly used for things that the speaker considers not too far in the future. Futur simple is for more distant future actions.

Answer

Chris, thank you for your reply but I am still confused. 'will do their home work and 'are going to do their home work, by your very answer means this action is going to be done right after lunch, like in the very near future right? It is simply a play on words and not necessarily an emphasis on the near or far off future.

Answer

Fiona, this is a subtle nuance only which, in some sentences, does make a difference.
For example: My stomach hurts,  I'm going to throw up. You wouldn't use "...I'll throw up" in this context, even though it's grammatically correct.
In many cases either is possible. But the distinction is more prevalent in French than it is in English.
