hope

[lourdes_lima]

I learnt the rules of using hope. I don't understand if hope can be used before a present perfect.
This is my sentence:
My class has entered a competition and we hope we've won first prize.

In my opinion it could be:

My class has entered a competition and we hope win first prize

Or
My class has entered a competition and we hope will win first prize

Thanks for your answer

My class has entered a competition and we hope we will win first prize.

You could also say:
My class has entered a competition and we hope to win first prize.

Some may even suggest that you use a comma after "competition" to provide a short pause between the two thoughts. It is not obligatory.
My class has entered a competition, and we hope we will win first prize.
My class has entered a competition, and we hope to win first prize.

I think you would hear people say "we hope we win" as well. My team is playing in the championship game Saturday. I hope they play well.

I learnt the rules of using hope. I don't understand if hope can be used before a present perfect.
This is my sentence:
My class has entered a competition and we hope we've won first prize. OK (OR "...that we've won first prize."

In my opinion it could be:

My class has entered a competition and we hope win first prize. No, but another option besides the one above could be "...we hope to have won first prize".

Or
My class has entered a competition and we hope we will win first prize. OR "...we hope to win first prize."

Hello b.

My class has entered a competition and we hope to have won first prize.
Has the competition taken place and is the speaker waiting for the results?

Best,
John

If the speaker is waiting for the results, "I hope we've won" is fine.

In the case of submitting / producing something, yes. But if entered means registering, then the statement, as such, would not be correct.

Thanks b. I see what you mean now. Excellent answer.
