Thanks a lot! I have the web site and got it from my university's writing center. I guess that the APA citation format of my paper need to be corrected. After I get the first part tomorrow, I will revise the rest part of my paper based on your comments and the correct (APA) style.&nbsp;<br /><br />Because I cannot separte the reference by parts, I am sending you all&nbsp;references. The total words of my reference are 4,395, and I know that I still miss some references. <br /><br />I do not understand what you mean about the references. Do you charge for references by words? I have 4,395, but I haven't counted how many words for the first part.&nbsp;<br /><br />Best,&nbsp;<br /><br />Wei<br /><br />&nbsp;
