English native speakers pls!

Hi I am a Hungarian living in UK for 5 years. I would like to setup a course in English and I ask you about an interesting question. When I create an English sentence and it is correct grammarly but there  is a difference from the original English what do you think about it and can you understand it? If i may tell you a Hungarian example I can make a difference between a native Hungarian and a foreign language one and maybe their Hungarian grammar is correct but the language structure is a bit strange of my native language...and unfortunately the meaning of their sentence used to be different what they wanted to inform us. 

For example The white door is open/The door what is white is open.    And I think my text of the course is full of the similar cases.   What do you think about it? Thanks Sandor

Personally, I wouldn't be happy with a course provided in what is essentially broken English.  If I enroll in a course that is taught in English, I expect the English to be spoken correctly.  

I don't want to have to expend mental capacity trying to figure out what the instructor is saying. I want to focus on the topic I'm trying to learn.  The same goes for instructors with heavy accents.
