Let’s start with this one. It’s correct. Before we continue it would be great where you found those sentences. Did you create them yourself? If so, why? When learning a language context is key and I can’t imagine any natural text where all those sentences occur in a row.
Yes, I created them myself and they do not occur in a row in a text, I merely wanted to know if my grammatical constructions were right, because I sometimes use them intuitively when speaking to somebody. Afterwards I sometimes wonder was this or that correct or not. Why I created those senteces? I haven’t got a clue. I guess I simply picked a person. No big deal.
Thanks for replying, Torsten, but I didn’t pick on the Queen, because that would mean I was teasing her and that’s not my intention. I simply choose somebody well-known and also famous. No, on the contrary I love the British Queen and all others of Europe. I certainly wouldn’t pick on her, all right?
Well, in ‘The Queen was rumoured to have been seriously ill.’ I find it as an incident of the past, that is, the rumour was spread in the past and her being alleged to be sick was in the past.
As Torsten has said, except for the repetition of second as the third (both are the same) all the sentences are grammatical. Ad they make sense as well.
