Answer:
In order to use <em>ethos</em> well, the student needs to establish his credibility with his teacher. The teacher needs to see that the student is truly responsible, however, due to circumstances beyond his control, the student tries to persuade the teacher to be more understanding.
Explanation:
The student may point out to the teacher just how much of a hard working, dependable student s/he is. The student has to emphasize his/her good standing with the teacher. But, since the student has, unexpectedly, been given more homework than s/he could manage at this time, the teacher, with his/her generous nature might be persuaded to either give an extension or postpone the due date of the homework.
