French language Q&A Forum

In the last sentence, "he has become" is translated "c'est devenu."  Why not "il est devenu"?

Some textbook said pire is for abstract noun while mauvais/e is for concrete noun

Could someone explain the subtleties of these three? 

I used 'environ' which was marked incorrect.

Each example of aux alentours de was paired with a 24-hour clock and vers with the 12-hour clock. Are they interchangeable?

In the text the English phrase "It is going to be great" is rendered in the proximate future as "ça va être sympa".

I understand why this is correct, but I'm wondering would French people ever use the simple future tense here instead?  Something like "ça sera sympa"?

Thanks,

Stuart
