the speaker's choice.
I discovered this expert's words:
In German, as in English, it is normal (my emphasis) to use any
abstract noun with the indefinite article when it is qualified by
an adjective or an adjectival clause."
I hope we should discuss questions seriously.Don't use a teacher or an expert says and so on.Our examples should be from publising.My examples are all from publising or dictionaries.Some important conclusions must be quoted from books.I think you are serious enough. I wil give you an example to turn down your conclusion.I have never come up with "to take active part in activities" so far.Have you?So we should go deeper.In my study I met with thousands upon thousands of such uncount nouns,admiration is only an instance.In my eyes it seems there is no rule in this respect.I am so dispaired that I think this is a matter of vocabulary ,not a matter of grammar.
