Here is another example of a simple error of omission that could have been caught if the student had read the essay aloud or given it to a friend to read. The word "of" should be between "calculation" and "the." That one small error makes the entire sentence awkward and confusing. If the instructor has to reread the sentence to try to understand its meaning, the flow of the essay is interrupted. If this happens often enough in the essay, it gives an overall bad impression on what otherwise might be a very good paper in terms of research.
“Sure I will, George. I won’t say a word.”
“Don’t let him pull you in—but—if the son-of-a-bitch socks you—let ‘im have it.”
“Never mind, never mind. I’ll tell you when. I hate that kind of guy. Look, Lennie, if you get in any kind of trouble, you remember what I told you to do?”
Lennie raised up on his elbow. His face contorted with thought. Then his eyes moved sadly to George’s face. “If I get in any trouble, you ain’t gonna let me tend the rabbits.”
Depending upon their types, different genres have different roles. For example, fiction and dramatic genres help students and writers learn and improve their communication skills. A poetic genre, on the other hand, enhances imaginative and emotional power of the readers. Non-fictional texts and essays help readers develop analytical and persuasive capabilities. However, the major function of genre is to establish a code of behavior between the writers and audience, and keep the readers informed about the topics discussed or the themes presented.
