Please correct my Japanese sentences.
 

日本ごのほさわいる。

I need help with Japanese. I have been studying it for a few months but the language is surely, a difficult one. I would like to practice writting sentences everyday and have somebody correct them for me.
Can anyone please help me out?

Throw out your sentences and I am sure you'll get some responses,

I'll help!!!

just PM me, I'm usually free you can IM me or email. I don't mind helping.

私輪にほんごをどとばんきょします。

What are you trying to say? I study Japanese?

Uhm. I will include an English explanation to every sentence from now on. ^^

I was trying to saｙ： "I have studied a little japanese."

I might write it as:

すこし日本語をべきょうしました。

Edit:

Maybe:
すこし日本語をべんきょうしていました。

If I'm not mistaken, the first would read like:
"I studied a little Japanese."
Whereas the seconds would be:
"I have studied a little Japanese."

I'm sure someone will come to correct me if its otherwise.

-te form + imasu is a progressive. (from the book)
-te form + imashita is a past progressive tense. (Just my thought)
Am i wrong ? or is it really perfect tense ?

I am native Japanese.

I have been worried about it.

I am studying English.
I have studied English.
I have been studying English.

If I translate them into Japanese by books
all "　私は英語を勉強しています　”

I think it is same the progressive form and the present perfect tense in Japanese.

And maybe the past progressive form and the past presetnt perfect tense are same.
