A little [bit] of English (It's more common to use the word "bit" when saying something like this.)

Hello! I am new here in Italky, my English[1] is not so [that] good, but i hope I it [2] will to get better in the next months. The other thing I can improve is my speaking, because on in [3] School all of the time [4] we are writing and studying the gramatical grammar, [5] but we never speak together. 

[1] The word "English" needs to be capitalized. Languages are always capitalized in English. Ex: Spanish, English, German, French, etc.
[2] In the previous sentence, you were talking about your English as not being good. In the next sentence, you were still talking about your English; therefore, you need to keep the same subject. So, I changed the "I" to "it". It = your English.
[3] English prepositions are a bit tricky, but you have to use "in" when referring to a building or location that you can physically be inside of. Example: I am in my house. I am in the garage. 
[4] "all of the time" or "all the time" is a very common expression in English. Example: I go to the store all of the time. I go to the store all the time. [Many people tend to leave the "of" out when using this expression.]
[5] "Grammatical" is an adjective, and in this sentence, you would want to use the noun form. You wouldn't need the article "the" in this example. 

Jasiel,

Polina,

There were just a few small errors in your journal entry, so I went ahead and made the corrections for you. In English, we use participles (the words that typically end in "ing") to express an action that is currently happening in the present. In order to use the participle successfully, you have to use a form of the "to be" verb. For example:

I am <participle> / I am swimming. Contraction: I'm
She/he/it is <participle> / She is hiking. Contractions: She's he's it's
They are <participle> / They are writing a letter. Contraction: They're
We are <participle> / We are talking. We're

If you have any questions regarding any of my corrections, please let me know. I am more than happy to help you in any way.

Very Respectfully,

Your journal entry was very well written! There were only a few errors here and there; however, I really enjoyed reading what you had to say. Keep up the good work. Also, if you have any questions about my corrections, feel free to ask me.

Brave boy,

Why do English native speakers not help us with our conversational skills? (I think this sounds better.) Also, what do you mean exactly by that statement? Native speakers aren't helping you better your conversational skills via voice communication, or are they just not reciprocating the help that you give them? It's a bit of an ambiguous statement. Also, I can't speak for all English native speakers, obviously, but I always make it a point to reciprocate equally while participating in language exchanges. 

Good luck!
