What is theyour favorite subject?

(1) The use of "the" is odd, since for a question that is directed at the reader or yourself, it comes across as quite impersonal.
(2) Alternatively: "My Favorite Subject".

My favorite subject is eEnglish.

"English" is the name of a language, so it's a proper noun and always capitalised.

Wll I like learning English because it can help me communicate with all of people around on the world.i In class,English gotta be help me practicing anything I practice everything in English and iI can knowlearn multiple new words or something.But . But it's especifically because my teachers is goodnesskind and always supports me when iI madke wrong imistakes. Important thatly, she makes the study environment study funny . In the future iI wanna visit to other countries to trylearn about their traditional,s, cultural,Ke, and knowledge. You know is, that is why iI really like to learn English.

SENTENCE 1
(1) "All of" is redundant, because "around the world" already conveys the same idea.
(2) "Around on the world" is ungrammatical, since both "around" and "on" are prepositions. The phrase is just "around the world" (or "from around the world").

SENTENCE 2
(1) Mind capitalisation rules. "In class" is the start of a sentence, so the "in" should be capitalised.
(2) I'm not sure what it means for English to help you practice "anything" in this context, especially given the classroom setting. Did you mean: "I practice everything in English"?
(3) "Learn" is the word to use here, rather than "know".
(4) Based on the native text, did you perhaps mean: "In class, I like learning multiple new words, practicing speaking and listening to English songs."?

SENTENCE 3
(1) The word to use here is "especially" and not "specifically". "Especially" makes a comparison: X is a reason I like learning English, but COMPARED to X, Y is a bigger reason.
(2) "Teachers" is plural, but "is" is singular. If you're referring to only one teacher (which seems to be the case here), you'd use the singular form of both words: "my teacher is kind".
(3) The word you're looking for to describe your teacher(s) is "kind".
(4) Similarly to (2), "support" is the plural form, while "supports" is the singular.
(5) The phrase is "make mistakes", not "make wrong".

SENTENCE 4
(1) Perhaps the word you're looking for is "importantly".
(2) The phrase is "study environment", and not "environment study".
(3) Note the spelling error in "enviroment".

SENTENCE 5
(1) "I" is always capitalised.
(2) The phrase is "visit (a place)", not "visit to (a place)".
(3) I'm guessing you meant "to learn about".
(4) "Traditional" and "cultural" are adjectives and do not stand alone. The nouns would be "tradition" and "culture".

SENTENCE 6
(1) When "you know" is used this way, it is more appropriate to place a comma behind it.
(2) "Is that why" is a phrase used in questions. For example: "Is that way I really like to learn English?" However, since what you wrote is a statement, the phrase to use is "that is why" instead.

Wll I like learning English because it can help me communicate with all sorts of people around on the world.i In class,English gotta be help m I like practicing just about anything and i can know multiple new words or something.But specifically mlearning new words. My teachers is goodnessreat and always supports me when i madke wrongmistakes. It's important that she makes the study environment study funny .fun. In the future i, I wanna (want to) visit to other countries to trylearn about their traditional,cultural,Knowledge.u know is thats and culture. That is why iI really like to learning English

'the study environment fun' - (Or: 'entertaining' if you meant funny as in 'makes me laugh')

wanna - Not incorrect, but very, very casual and a little odd in the context of a public journal post. 'Want to' is far more common and natural in this context.

"Gotta" and "wanna" are slang; use "got to" and "want to" for proper English. Also, "I" is always capitalized. Typing "u" instead of "you" is commonly done in text speak, but not correct English.

The second sentence did not translate very well, I think some of your message may have been lost here.
