to make a better city, planners aimed at creating a city in which the insalubrious environment and social structure would be defeated by a reordering of physical and social arrangements, so that all the citizens could attain the benefits of beauty, community, and

democracy. in harvey’s opinion, the better city should confront on the postmodernist challenge to political economy, and deal with environmental sustainable.

however i think green buildings could make good cities, and also citizens will have a best quality of life. according to the world green building council’s definition, “to significantly reduce or eliminate the negative impact of buildings on the environment and on the building occupants, green building design and construction

practices address: sustainable site planning, safeguarding water and water efficiency, energy efficiency, conservation of materials and resources, and indoor environmental quality.”the green building, which is sustainable in the built environment, can reduce

environmental impact but also provide better buildings. the

technologies associated with green buildings include:

-energy conservation

-water conservation

-material selection

-use of renewable materials

-occupant health and indoor environment quality

-site ecology

-recycling

the green building can be residential, commercial, retail and industrial buildings. for example, the green building uses water-

mining plant to recycle water on toilet flushing, watering the garden, and washing cars. the building also uses phase-change materials for cooling, automatic night-purge windows, wavy concrete ceilings, which saves a lot of money and become more sustainable.

the idea of green and healthy cities is becoming more important nowadays. the better city should be planed for health and well-being by planners, and they will mainly focus on service facilities,

educations. the good city will also need to be safe in community, and make community more walkable, and has an urban design with exquisite streetscape. however the planner keeps developing new ideas of how cities should be changed, therefore the city will become more livable and sustainable in the future.

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?
