Philosophy help

I am writing an essay for my intro to ethics class and need some help. I go to class every day and read all the readings but still have trouble grasping the concepts of this class. I have to write about one of these four questions and any help would be greatly appreciated. I am not looking for someone to write my essay, i simply would like someone to explain the answers in simple easy to understand terms. The readings confuse me and the teacher is not very helpful when you ask him questions. He is one of the professors who is really to smart to teach, and expects you to know everything. The four questions are...

1. What relationship, if any, is there between religion and ethics? Discuss any two (2) thinkers from Kant, Kierkegaard, and Mill, and come to your own critical understanding on the question.

2. Both Kant and Kierkegaard can be viewed as offering a non-teleological ethic. What similarities and differences do you see between their respective understandings of non-teleology? Come to your own critical understanding on the validity of non-teleology.

3. Kant, Kierkegaard, and Mill, in their own way, can be understood as representative of ‘modern’ moral theories. Briefly discuss how modern moral theories may differ from pre-modern forms and select any two (2) thinkers to address how they may or may not be ‘modern’ moral theorists.

4. Select any two (2) thinkers from Kant, Kierkegaard, and Mill, and discuss the relationship between reason, desire, passion in the moral life. Come to your own critical understanding on this issue.

Thank you for any help.
