It bothers me a lot,therefore,I want to have it written down .I am a student.I have been studying English for almost 5 years,but I have never leaned how to write a decent paragraph without mistake.I have thought of giving up learning english,but on the other hand ,I want to keep trying because the country in which i live uses Enlish for daily business .I have problems with pronouncing and spelling .I always forget things that I have just learnt. Sometimes I wonder if there is anything wrong with my memory.Today my teacher collected our class essays and outside class essays for the final semester portfolio.I didn't do well on either one of them. My grade barely reaches the passing grade.On my paper there are always a lot of mistakes such as incorrect use of preposition,pronoun ,sentence akward ,run on sentence,etc (sorry not sure what exactly you are talking about here).I am fed up with this .What shall I do? Shall I quit school or continue to study? I know there are a lot of mistakes. Please correct them for me .I know it will take you a lot of time,but I still hope you can correct me.Thank you for your time reading my question.I am look forward to seeing your answer.
