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.

第四篇：英語animation專題ppt演講稿

我非常榮幸能到前面來演講 ，這就是我這次的主題——動漫

i am much honored to come to the front speakers; this is my current theme - animation

早在1831年，法國人joseph antoine plateau把畫好的圖片按照順序放在一部機器的圓盤上，圓盤可以在機器的帶動下轉動。這部機器還有一個觀察窗，用來觀看活動圖片效果。在機器的帶動下，圓盤低速旋轉。圓盤上的圖片也隨着圓盤旋轉。從觀察窗看過去，圖片似乎動了起來，形成動的畫面，這就是原始動畫的雛形。

as early as 1831, the french joseph antoine plateau in order to draw a good picture on a machine in accordance with the disc, the disc can be driven by rotation of the machine. this machine also has an observation window to watch the activities of picture effects. the machine, driven by low-speed rotating disk. the picture on the disc along with the disk rotation. from the observation window at the past, pictures seem to move together to form a moving picture, which is the prototype of the original animation.

1909年，美國人winsor mccray用一萬張圖片表現一段動畫故事，這是迄今爲止世界上公認的第一部象樣的動畫短片。從此以後，動畫片的創作和 製作水平日趨成熟，人們已經開始有意識的製作表現各種內容的動畫片

in 1909, americans winsor mccray performance with a million images an animation story, this is by far the worlds recognized as the first decent animation clips. since then, the level of animation creation and production of mature, people have started to make sense of the performance of various elements of the cartoon.

1926年 萬氏兄弟成功的發展了中國第一部動畫片 這也是中國美術的里程碑。

in 1926, wang’s brother successfully developed china's first cartoon it is also the beginning of chinese art pieces.

動漫有以下三種風格 歐美風格 中國風格 日式風格

there are three styles of europea(請關注：)n and american animation style of chinese-style japanese style 無論如何，有不同的動畫給了我們巨大的喜悅。它作爲一個媒體，使用或幽默誇張的款式或到社會現實的陰沉深的形式還指導我們的成長。也是一個非常有前途的行業?

anyway, have a different animation gives us immense joy. it also guided our growth as a form of media, use or exaggerated style of humor or the gloomy deep into the social reality. is also a very promising industry ~

最後 讓我們看一個動漫小視頻

finally, let us look at a small animation video

thanks~

1、lathe [leie]

2、value of two yuan of the third series of the rmb ——the turner

3、a lathe is a machine tool which rotates the workpiece on its axis to perform various ['vε?ri?s] operations such as cutting, sanding(砂磨), knurling['n?:li?] (滾花), drilling, or deformation with tools that are applied to the workpiece to create an object which has symmetry['simitri] (對稱) about an axis of rotation.（center lathe，vertical lathe）

4、history

the lathe is an ancient tool, dating at least to ancient egypt ['i:d?ipt] and known and used in assyria [?'siri?] and ancient greece [ɡri:s].

the origin ['?rid?in, '?:-] of turning dates to around 1300 bc when the ancient ['ein??nt] egyptians [i:'d?ip??nz] first developed a two-person lathe. （one person would turn the wood work piece with a rope while the other used a sharp tool to cut shapes in the wood.） ancient rome improved the egyptian design with the addition of a turning bow. in the middle ages a pedal replaced hand-operated turning, （freeing both the craftsman's hands to hold the woodturning tools. the pedal was usually connected to a pole, often a straight-grained sapling.） the system today is called the "spring pole" lathe. spring pole lathes were in common use into the early 20th century.

during the industrial revolution, mechanized ['mek?naizd] power generated by water wheels or steam engines was transmitted to the lathe via line shafting,( allowing faster and easier work. metalworking lathes evolved into heavier machines with thicker, more rigid parts.) between the late 19th and mid-20th centuries, individual electric motors ['m?ut?] at each lathe replaced line shafting as the power source. beginning in the 1950s, servomechanism[,s?:v?u'mek?niz?m, 's?:v?u,me-] (伺服機構) were applied to the control of lathes and other machine tools via numerical control, (which often was coupled with computers to yield computerized numerical control.) today manually controlled and cnc lathes coexist（共存） in the manufacturing industries ['ind?stri].

5、description：parts

explanation of the standard components of most lathes:

? bed牀身: usually made of cast iron. provides a heavy rigid frame on which all the main components are mounted.

? ways牀身導軌: inner and outer guide rails that are precision machined parallel to assure accuracy of movement.

? headstock['hedst?k]牀頭箱，主軸箱: mounted in a fixed position on the inner ways, usually at the left end. using a chuck, it rotates the work.

? gearbox ①齒輪箱②變速器: inside the headstock, providing multiple speeds with

a geometric ratio by moving levers.

? spindle['spindl]心軸，主軸: hole through the headstock to which bar stock can be fed, which allows shafts that are up to 2 times the length between lathe centers to be worked on one end at a time.

? chuck卡盤: 3-jaw (self centering) or 4-jaw (independent) to clamp part being machined.

? chuck: allows the mounting of difficult workpieces that are not round, square or triangular.

? tailstock尾架: fits on the inner ways of the bed and can slide towards any position the headstock to fit the length of the work piece. an optional taper turning attachment would be mounted to it.

? tailstock quill[kwil]尾架套管: has a morse taper to hold a lathe center, drill bit or other tool.

? carriage托架，滑動架: moves on the outer ways. used for mounting and moving most the cutting tools.

? cross slide橫刀架，橫拖板，橫溜板: mounted on the traverse slide of the carriage, and uses a handwheel to feed tools into the workpiece.

? tool post刀架，刀座: to mount tool holders in which the cutting bits are clamped. ? compound rest複式刀架: mounted to the cross slide, it pivots around the tool post.

? apron['eipr?n]牀鞍: attached to the front of the carriage, it has the mechanism and controls for moving the carriage and cross slide.

? feed rod進給杆: has a keyway, with two reversing pinion gears, either of which can be meshed with the mating bevel gear to forward or reverse the carriage using a clutch.

? lead screw絲槓: for cutting threads.

? split nut開合螺母: when closed around the lead screw, the carriage is driven along by direct drive without using a clutch.

? quick change gearbox快換齒輪箱: controls the movement of the carriage using levers.

? steady rest固定中心架: clamped to the lathe ways, it uses adjustable fingers to contact the workpiece and align it. can be used in place of tailstock or in the middle to support long or unstable parts being machined.

? follow rest跟刀架: bolted to the lathe carriage, it uses adjustable fingers to bear against the workpiece opposite the cutting tool to prevent deflection.

6~9、description：accessories [?k'ses?ri]

three-jaw [d??:] chuck [t??k]: self-centering three-jaw chuck and key with one jaw removed and inverted showing the teeth that engage in the scroll plate. the scroll plate is rotated within the chuck body by the key, the scroll engages the teeth on the underside of the jaws which moves the three jaws in unison, to tighten or release the workpiece.

four-jaw chuck :independent four-jaw chuck, also known as a universal chuck, with the jaws independently set. the key is used to adjust each jaw separately. collet彈性夾頭: a collet ['k?lit] is a holding device—specifically, a subtype of chuck—that forms a collar around the object to be held and exerts a strong clamping force on the object when it is tightened, usually by means of a tapered outer collar. it may be used to hold a workpiece or a tool.

faceplate花盤: a lathe faceplate is the basic workholding accessory for a wood or metal turning lathe. it is a circular metal (usually cast iron) plate which fixes to the end of the lathe spindle. the workpiece is then clamped to the faceplate, typically using t-nuts in slots in the faceplate, or less commonly threaded holes in the faceplate itself.

dead center死頂尖: dead center (the conical piece) mounted in the spindle of a lathe and being used to support a workpiece being driven by a carrier setup live center活頂尖:a live center or revolving center is constructed so that the 60° center runs in its own bearings and is used at the non-driven or tailstock end of a machine.[2] it allows higher turning speeds without the need for separate lubrication [,lu:bri'kei??n], and also greater clamping pressures.

lathe carrier['k?ri?]車牀雞心夾頭: a lathe dog, also known as a lathe carrier, is a device that clamps around the workpiece and allows the rotary motion of the machine's spindle to be transmitted to the workpiece.

mandrel['m?ndr?l]心軸: an object used to shape machined work.

10、application

lathes are used in woodturning, metalworking, metal spinning（旋壓）, and glass-working. lathes can be used to shape pottery, the best-known design being the potter's wheel陶車. most suitably equipped metalworking lathes can also be used to produce most solids of revolution, plane surfaces and screw threads or helices. ornamental [,?:n?'ment?l] lathes can produce three-dimensional solids（實體）of incredible complexity

11、examples of work produced from a lathe

12、thank you!

i`m very happy to have this opptunity to give you a y,my topic is lathe.

i know many of you are familiar with this topic

can you hear me clearly?

i think ti would be best to start out by looking at the picture on the screen

i would like to talk about first is the definition of the lathe

question ['kwest??n]

that is all,thank you very much

do you have any questions? please show me your hand.

who else?

i think we have time for just one more question
