What would a good city look like? 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. Reference: Susan S.

一、英语演讲稿如下：

Change:

Leo Tolstoy once said, everyone thinks of changing the world, but no one thinks of changing himself.

He is right. We always have great plans and dreams in our minds... too ready to achieve something gr and that changes the world or benefits all of mankind.

For example; we hate pollution and have made up our minds to find new energy sources that keep the environment clean.

Yet we still litter on the ground. We complain about traffic jams, so we plan to build more highways to solve the problem, but it never occurs to us that our failure 0 follow traffic regulations is the leading cause of this situation.

We are so concerned that the violence in the media has a bad impact on our children, we urge the government to set laws to protect them. But, do we, as adults, set a good example for our kids?

n the ground in front of them,I dare to say, veharm more!

In my opinion, before we decide to change the world, we had better change ourselves first. As ordinary individuals, we do not have the power to change the world. But we can change our ha bit of littering, spitting, cussing, we can respect the env ironment around us, we must act as good models for our kids.

If each ofus does all of these little things, all of us, millions and millions of individuals together, together we will be strong ..strong enough to change our world!

So please, the next time you do something, think how your actions influence not only you, but those around you too, especially our children and perhaps more importantly our planet!

二、译文如下：

改变：

列夫托尔斯泰曾说过：每个人都想改变这个世界，但是没有人想到改变自己。

他说的很有道理，我们每个人都心怀伟大时志向，时刻准备去干一番能造福全人类的大事业。比如，我们痛恨环境污染，所以我们下定决心去开发新的更高效更干净的能源来保护我们的环境。

但是同时我们却随手乱扔垃圾，我们抱怨大城市的交通堵塞，计划造更多的高速路来解决交通问题，但是我们从来没有想过，如果我们能遵守交通规则话，那么这一问题是不是可以得到很大得缓解呢？

我们担心电视电影里面得暴力会对我们得孩子产生不良的影响，于是我们敦促政府通过立法来保护未成年人，但是我们这些大人又做得怎么样呢？我们为我们的下一代做好了表率吗？我们说粗话，甚至在孩子面前抽烟。不客气地说，我们对孩子的不良影响更多！

在我看来，在我们打算改变这个世界之前，我们最好先改变一下自己。 作为一个普通人，我们其实没有改变这个世界的能力，但是我可以改变我们随地扔垃圾，随地吐痰的坏习惯，我们应该学会去保护环境，我们应该为我们的孩子起好的表率作用。

如果我们每个人都能从事起，那么千千万万个力量汇聚在一起，那力量是强大的，以改变这个世界。

朋友，当您在做某一件事情的时候， 请您想一想，您的行为会对您周围的人产生怎样的影响，因为，您的行为不单单影响到您自己，还有您周围的人，更重要的是我们的孩子甚至我们的世界。
