why do you want to learn new language? i think that there are diffrence reasons for everyone

I offer that we can help each other in this site

For example we can talk online together. everyday, one person can teach one way to learn english. i think that ifyou want to improve your english you have to watch film in english with subtitles

We have to use grammar very correctly while to speak new language or it is not important?

i think that it is not important  for speaking but if we want to be profisional person we have to use accuratly

First class. we talk about 'to be ' everyone can write here about it I- am (present tense) We/You -are(present tense) He/She/it - is( present tense) IF we talk about something , it happen in past I/It/He/She/ -was. (past tense) we/you-were ( past tense)
