Hello,&nbsp;<br /><br />I am an international graduate student. So, I want to check my expression and grammar in this draft for American reader.&nbsp;My professor is very sensitive to writing so that I want to develop my wrting through your service. <br /><br />This is a research proposal. I am confused the tense of sentence, especially in case of literature review section. my professor require me to use present tense through. <br /><br />Anyway, please check my draft. I am planning to&nbsp;submit ths paper to professor tomorrow. <br /><br />thanks. &nbsp;
