Second note entry.

I decided to "write about learning a language". This is the one of many interesting themes that Italki offers.
So, I've been learning English for a long time but I have some problems with it. Sometimes I think English grammar is the hardest thing for me.))))))) All is not so bad though.) I`m reading articles, memorising some songs, I can understand 50% of what English speakers say.
My biggest problem is written English. It`s so difficult for me even though I have a good English vocabulary and know certain grammar rules. I think my problem is the inability to apply all these things...
Second problem accordingly is speak English.

Can you correct this text and take my any advice, please?

So, I learn have been learning English for a long time but I (still - необязательно, но так и напрашивается тут: "Но у меня все еще есть проблемы... - But I still have problems...) have some problems with it. Sometimes I think English grammar is the hardest thing for me))))))) All It is not so bad) (Вообще тут лучше сказать "It is not too bad"; я знаю, ты хотела сказать "Все не так уж и плохо", но по-английски тут ни all, ни everything не подходят). I`m reading articles, memorizing some songs, can understand 50/50 of what English speakers say.
My first problem is to write in English. It`s so difficult for me although I know many necessary words and needful useful/some/basic Grammar rules. I think my problem is the inability how to apply all this these things...
Second problem accordingly is speak concerns speaking/is speaking/is spoken English.

Будь внимательнее, когда читаешь на английском. Ты увидишь, что не всегда native speakers говорят так, как ты сама бы сказала. Употребляют не то время, которое ты бы употребила. Чем больше будешь обращать внимание на эти differences, тем меньше ошибок будешь допускать сама. Удачи =)
