Good morning everyone:
My name is Yang Chen.It's my honor to stand here to show our team's PPT.As we can see from the screen.Today our topic is about the introduction.Well,let's begin. We will divide four parts,the first one is that what is introduction, and the second is establish the topic and Literature review. The third one is Investigation needed and Purpose of the research, and the last one is Value of the research and Outline of the research. and my work is this part what is introduction.First we should know the definition of the introduction,introduction is often used as the beginning of the paper,it tells us why the author writes it, and summarized the paper.According to the definition,we knowthe location of the introduction at the start of a piece of academic writing.And its purpose is that situate research,give background,present research problem,say how and why this problem should be solved.There are some examples.We can see clearly the location of the introduction at the start of the paper.And this example tells us the purpose of the introduction, (读红字)The safety field of future vehicle can be divided intopassive safety system and active safety system.//Give background of the research
(读蓝字)However, these methodsare considerable complicated, and for this reason we usegeneral and simple classifiers and compare theirperformances to emphasis on practical use//tell us the present research problem and say how and why this problem should be solved
(读灰字)The remaining of this paper is as follows: In section 2,brief review of the active safety system andclassification methods are given. //Tell us the substance of each part
And this example.
(读红字)give background of the research
(读蓝字)tell us the present research problem and say how and why this problem should be solved
(读灰字)Tell us the substance of each part
It is not a coincidence，it is a general character.
Now,we have known that what is introduction,but we still have some questions.such as How to start the Introduction?What type of information should be in my Introduction, and in what order?How to end the Introduction? Those questions will be solved by my teammates. Thank you.
