I am leaving this school in whichwhere I taught for almost a year.

My friend said that it is always my department in which has the most teachers leave

Our department areis always isolated from the other departments due to thea language barrier.

In our department we speak Chinese while other departments speak English.

Few of teachers in my adepartment can speak English fluently, s. Some can speak basic English but not good enough to chat with other teachers like me, and others can

not speak English at all since the English level is neverwas not a job requirements of for our department.

Those who can speak English in our department always have to be the translator for those who can not speak English, and the president prefers to assign more jobs to the ones who can speak English more job, w. Which I can totally understand because that would bemakes it easier for them to communicate.

My conclusion is from my observation that we are always busy (we need to set practice papers, correct the homework, mark the exams, give remedial lessons to students.), while others teachers can chat with each other, play mobile games，and laugh loudly almost everyday.

It is like atwo different worlds, one is a happy paradise, the other is a hell, aleven though we are in the same office.

I still don't know why it is, but those two reasons ( the language barrier and overloading ) might be why my department haves the most teachers quitting the job every school year.

"Good" is the adjective; "well" is the adverb.

Others cannot speak English at all since the English levelcompetency is never a job requirements of for our department.

"Cannot" is typically the word that you want. "Can not" is used only ironically or to in a positive sense to indicate that something can be avoided.

Those who can speak English in our department always have to be the translator for those who can not speak English, and the president. The principal prefers to assign more jobs to the onose who can speak English more job, which I can totally understand because that would be easier for them to communicate.

Aside from thosee reasons I mentioned above, it looks like our department is the busiest department.

My conclusion is from my observation is that we are always busy (we need to set practice papers, correct the homework, mark the exams, give remedial classes to students.) while others teachers can chat with each other, play mobile game，game on their phone, and laugh loudly almost every day.

"Everyday" is the adjective; "every day" is a phrasal adverb for time.

It is like a different world,: one is a happy paradise, and the other is a hell, although we are in the same office.

president = leader of a country. If you meant the leader of the school, that would be the principal.

My conclusion is, from my observations, that we are always busy (we need to set practice papers, correct the homework, mark the exams, give remedial(?) to students.) while others teachers can chat with each other, play mobile game，s, and laugh loudlyhave fun almost everyday.

I'm not sure what you mean by 'remedial'.

It is like a different world, one is a happy paradise, the other is a hell, aleven though we are in the same office.

I still don't know why it is like that, but those two reasons ( the language barrier and overloading strain) might be why my department have the most teachers quitting the job every school year, every year, most teachers who quit are from my department.
