I passed a TEFL certificate test, and there was a sentence:
"We are going to stay with our family in Aberdeen."
And I had to choose whether it was "Future SIMPLE with "going to"" or "Present Continuous used as a future form", I chose the latter, as it was the closest ( the best answer would have been ""be going to" as a future tense/form (not SIMPLE)". And it says this is the wrong answer. The comment I got from them is this:
am/are/is + going + infinitive of main verb
(NB: 'I am going to Paris' is present continuous as a future form with 'going' used as the main verb; it's not future simple with 'going to' as long as 'Paris' is not a verb).
It's not Future Simple, Future simple is about will and shall. There's a reason we call all those tenses "Simple", isn't there?
