Пожалуйста помогите с английским.
Скажите в каком времени употреблены эти предложения. Очень прошу помогите.


Everybody at school (is talking) about the big Valentine's Day Dance that (comes) up next week.
This is the first year at my school a dance is being actually (organized), so everyone is excited.
Before Valentine's Day I was up late (making) Valentine's cards for everyone in my class.
Then I (had) a great idea: instead of saying things I (did not mean), I told everyone what I (thought) of them.
The trick was, I (did not write) my name on any of the cards.
Some of my cards (were given) to our teacher, Mrs Riser.
She went around the room (trying) to understand who (had sent) them.
I knew it (would happen).
That's why I (had made) a card for myself too.

Past progressive и Past simple (это по моему)

1. Present Continuous / Present Simple2. Это пассив. (Иными словами говоря, - страдательный залог)3. Здесь Past Simple, a герундий making просто дополняет глагол. 4. Past Simple5. Past Simple6. Пассив7. Trying - герундий, само предложение в Past Simple, а глагол had sent - это Past Perfect.8. Past, но Would - это прошедшая форма от глагола will. 9. Past Perfect
