Robert is correct in both cases. I will add my two cents just in case further clarification is needed or a different perspective.
is added after verbs to emphasis that someone should do something well or carefully as Robert indicated. However, it is also used to soften an imperative/command so that the speaker doesn't sound so bossy. For this reason, we often don't translate the 'bien'
because it add excessive stress or softening where we don't often put it in English (or if we do, we would say 'please
', but that doesn't work here).
It is tempting to translate everything literally but in this case I would leave it as is and just understand that the French and English equivalents as they stand carry the same weight/stress.
- JAMAIS - Alors écoutez bien Rocket French et vous n'aurez jamais de problèmes! If we just had 'jamais', then the English equivalent would be much the same: "So, listen to Rocket French and you'll never have problems!"
- PLUS - Alors écoutez bien Rocket French et vous n'aurez plus de problèmes! If we only had 'plus', the the English would be: "So, listen to Rocket French and you'll have no more/no longer have problems!"
- PLUS JAMAIS - Alors écoutez bien Rocket French et vous n'aurez plus jamais de problèmes! If we have 'plus jamais', the English should be: "So, listen to Rocket French and you'll never have problems!" or "So, listen to Rocket French and you'll never have anymore problems!"
The distinction between 1 and 3 is that 1 implies you will not have problems in the future, while 3 implies that you may have had problems up to now, but in the future you will no longer have them.
Why is it 'never have problems' instead of 'never have anymore problems'? Similar to the issue with 'bien'; it's a question of politeness. In French, it must be 'plus jamais', but in English it doesn't and the tendency is to focus on the positive, future solution, not stress the current difficulties.
I realise literal translations can appear preferable, but it can degrade the overall sense or tone of a sentence.
I hope this helps and hasn't muddled things further.
