每次临睡前，我都有阅读的习惯。昨晚临睡前，顺便阅读了一下娜儿从英国寄来的资料，其中关于introduction/discussion/bibliography的论述甚好，现summarise如下：

     1、Introduction

     In an essay introduction,you should set out your main themes and intentions: describe the issue you are addressing,identify its main components,and indicate what you are going to do in the body of your essay.

     2、Discussion

Bing asked to discuss something is not the same as being asked to list things.A discussion will consider alternative points of view. Your own thinking and evaluation should be apparent in the discussion of the topic.

     3、Bibliography

     Listing a reference in the bibliography does not make it acceptable to copy sections of the book into your essay.You must summarise the points in your own words.
