Swimming Pool

Usually, I go to the swimming pool twice a week.

However, the nearest pool from my house is now being repaired so I haven't been to the swimming pool these days.

It's still uncertain when it'll be opened again.

I hope it'll be opened soon.

Very nice! This is a nearly perfect notebook entry. Dont forget to use your articles like "the" and the word "will" like in "it'll" which is "it will" gives the sentence a bit of a future tense which means you want to use just "open" and not the past tense of "open" which is "opened." Keep working at it!
