Here are my opinions. Original: Earlier today, My teacher didn't give me the access to the class.I think I deserve that because I was late. My take: Earlier today, my teacher didn't allow me to stay in class. I think I deserved that, because I was late. (I'm trying to understand what you mean by "access", as it is not a word I'd choose here.) Original: 2 - The accommodation in this hotel has been relaxing. It has been very quiet and the serving has been very smooth. I recommend it to you. My take: The accommodations in this hotel have been excellent. It has been very quiet, and the service has been very smooth. I would recommend it to you. (Although "relaxing" works, I have a personal preference for "excellent" over "relaxing" in this sentence. I don't normally associate the words "accommodations" and "relaxing" in that manner.) Original: 3 - I am harsh with you now, because I am trying to teach you how to depend on yourself. In your aduthood, there will be a lot of responsibilities. I am preparing you for that. My take: I am harsh with you now, because I am trying to teach you how to depend on yourself. In your adulthood, there will be a lot of responsibilities. I am preparing you for that. (This is almost perfect, except you misspelled "adulthood".) Original: 4 - If you have a good advertising department, you will accomplish good sales rates. Thats why I am so keen in selecting my adversing team. My take: 4 - If you have a good advertising department, you will accomplish good sales rates. That's why I am so keen in selecting my advertising team. (Only a few spelling errors here.)
