before +past perfect

AnonymousI did not go to this restaurant before

These are the usual ways to express those thoughts.

When you are there for the first time:

I have not been to this restaurant before.
I have never been to this restaurant before.

ok, so could you let me know why in a test, I was wrong when I answered "had known" instead of "did know "
Here is the sentence

Before Kyoto no one did know about global warming;
I answered "had known" because for me it was before Kyoto took place that no one had known about global warming . and not before Kyoto takes place no one did know about global warming

Anonymous I was wrong when I answered "had known" instead of "did know "Here is the sentence 'Before Kyoto no one did know about global warming'

'Did know' is not possible in that sentence. 'Knew' is the standard choice, since 'before' clearly indicates the order of events. Past perfect is not wrong, however, if the writer wishes emphasis.

Did know is unnatural. Before Kyoto no one knew about global warming would be the usual way to say this. Since know is a continuous state, (once you know something you theoretically continue to know it) it is usually stated in the simple past. Before "X" I did not know "Y". After "X" I did know "Y". If your sentence used heard i

OK But I dont understand why we say
No one knew about global warming before Kyoto.(1) and
no one had heard about global warming before Kyoto (2)

No one heard about global warming before Kyoto
For me these sentences (1,2)are very close so they should used the same tence past simple or past perfect

Thanks for answering

The two sentences convey the same general idea, but knowing is an ongoing situation, a condition that exists, so we are effectively saying people were, or were not, in the condition of knowing about global warming before Kyoto. Heard

I understand
Why No one heard about global warming before Kyoto means that nobody was hearing any discussion of global warming because nobody was talking about it.Does it mean that Kyoto did not have an important impact on global warming and that Kyoto event was not really related to global warming that is why the use of past simple ?Would you mind trying to explain it to me

No, that's not what I was trying to say. I meant that if you say "No one heard about global warming before Kyoto" it would suggest that it was not something that peo

But it is the same as "No one had heard a bout global warming after Kyoto". That also means that after Kyoto many people talked about it. I don't catch the difference?!

had heard Some people spoke about global warning but there were very few., not enough to be heard
heard No one spoke before but plenty of after.

Is it the difference? And why

Many t

No one had heard about global warming before Kyoto = most people had not been told about global warming, and did not know about it, before Kyoto. It implies that Kyoto led to the news of global warming becoming well-known. This phrase refers to how many people knew about global warming.
No one heard about global warming before Kyoto
