English speaking room

Frankly speaking i have some knowledge, but a think i must concentrate on:

1. Spelling - Please tell me if i made wrong tense construction.
2. New sentences - Like an "Rain cats and dogs". Please use them and translate in ().

I think i will have learned new worlds in communication.
May by i must strike off some tense at the beginning, like as Perfect progressive?
I have problems with choice right tense
