Before he announces

[tufguy]

Hi guys,

Please check. "I knew I could finish my chit chat before professore announced anything" or "announces anything". We have to use past here right? But we have to use present sometimes with past tense. So when to do that?

I would say "announced" is correct in this sentence.

Can you write an example of a sentence where present and past tense must be used?

Note: '...before the professor announced anything'.

"Yesterday I brought some eggs and put them into fridge so that they get freezed. So that when I break them, yellow part did' t get mixed up with white part". Is it correct? If we have to use present in the "break" part so what is the reason? and did I have to use past after this sentence or not?

If 'when I break them' refers to a future action, I will use the simple present. And I will say 'won't mix with' instead of 'did' t get mixed up with' if it also refers to the future.

I would say: Yesterday I brought some eggs and put them in the fridge to freeze. The second part of the sentence has been explained by Mathew; will must be used.


P.S. No "freezed" but "frozen".

yellow part... white part...

I would call them 'the yolk' and 'the white'.

Mathew

I would spell it with a double t.

The "fridge" does not "freeze" anything. The "freezer" does that.

when I break them

Will frozen eggs break open by themselves due to expansion?

I have no idea. I have never tried to freeze an egg.
