汽車演講稿篇一：私家車的影響演講稿
Honorable judges, ladies and gentlemen:
Good morning!
My name is XX, a second-grade postgraduate student from school of XXin XX. Today, I want to talk about the topic “Choose green travel, lead a low carbon life”.
With the rapid development of economics and increase of urban population, more and more people buy and use their own cars. Yet opinions of private cars vary from person to person. From my perspective, I don’t think the advantages of this trend for individuals overweigh the disadvantages for environment.
Certainly,no one can deny the fact that there are so many advantages to drive private allow us to pursue high speed, strong passion and personal freedom. We can go anywhere at any time instead of waiting for a long time just to find the bus is full or the environment is so noisy. Owning a car even becomes a fashion and the symbol of status and wealth to some degree.
However, the disadvantages can’t be ignored. Well, everyone, have your city been suffered from haze weather? Are you forced to wear the mask to avoid breathing poisonous air? Perhaps most people here will say “yes”. A horrible fact is that the vehicle exhaust accounts for more than 20 percent of the sources of haze in China. Except for the air pollution, the noise caused by the sound of car
horns also threatens people’s health.
All in all, there are many things we can do to improve our environment. In my opinion, we are supposed to choose green travel which means we should take public transportations,such as buses,subways and public bicycles, or carpool with friends when we go out to minimize the use of private cars. No matter how hard it is, as long as we understand the importance of protecting our environment, take action to choose green travel and lead a low carbon life, our lives will be better.
That’s all, thank you!
Besides,we can’t ignore thebenefits that public transportation brings tly,it’s beneficial to eliminate the problem of parking we all know,owning to the increase of private cars,the issue of parking space is terribly ndly,it’s effective to ’s time for us to save resources,or we’ll regret sooner or but not least,it’s efficient to relieve air ,the earth was an ideal place to live sky was blue the air was clean and rtunately,the earth is not the same as ’s suffering from severe pollution.
Ladies and gentlemen,have you ever noticed that our streets are becoming more and more crowded?Have you ever realized that many resources are not inexhaustible?Have you ever realized that our environment is deteriorating?I believe most are aware of these let’s take action from now you are not in a hurry for something ,please take a bus instead of driving your own car;when you are going to travel,please endeavor to choose public transportation rather than private cars;when you are tired of the bad atmosphere because of public transportation,please bear in mind you are sacrificing the temporary comforts for a good environment.
We can’t live without also have only one common home –the each one of us can make a contribution to it,we will make our home a greener place to live in ,not only for ourselves,but for many generations.
汽車演講稿篇二：汽車知識講稿
一、 汽車的發明與發展
（一）汽車誕生之前，馬車就是人類最好的陸上交通工具。
（二）卡爾?奔馳 就是現今德國大名鼎鼎的“奔馳”汽車公司的第一代祖宗，戴姆勒--奔馳汽車公司的創始人之一。 他被稱為“現代汽車之父”。
他在英國人瓦特發明蒸汽機和德國人奧托發明內燃機的基礎上，開始思考把發動機按在車上，代替馬。
? 1878年開始研究新型內燃機。
? 1879年首次研製成功火花塞點火內燃機。
? 1882年開始嘗試把發動機安裝在三輪車上。
? 1885年他的三輪車研製成功。
? 1886年1月29日獲得專利，被公認為世界第一輛實用的汽車。 ? 德國另一為工程師哥特里布·戴姆勒也同時造出了一輛用1.1
馬力汽油發動機作動力的四輪汽車。
? 1883年，他發明成功了世界第一台高壓縮比的內燃發動機，成
為現代汽車發動機的鼻祖。
? 1926年，奔馳和戴姆勒公司合併成為戴姆勒-奔馳公司，生產“梅
塞德斯-奔馳”牌汽車
進入20世紀以後，汽車不再僅是歐洲人的天下了，特別是
美國的亨利· 福特。1908年福特“T”型車問世，福特流水式
生產線建成，開始了嶄新的汽車生產方式。初期的汽車還有使用實心木輪的，後來使用了自行車所用的輻條式的鐵製車輪，外套實心橡膠輪。這種實心輪當車速超過16km／h時，車就會跳起來，使司機和乘客顛簸得無法忍受。英國人鄧洛普發明了用於自行車的充氣輪胎後不久，1895年，法國的米芝蓮兄弟就製造出了用於汽車的充氣輪胎，使汽車行駛的舒適性大大提高。
（三）中國汽車發展歷史
1.無汽車工業時期
2.創建階段（1949～1965年）
3.成長階段（1966～1980年）
4.全面發展階段（1981～2000年）
5.飛速發展階段（2000年～至今）
二、 汽車品牌與文化
福特汽車的標誌是採用福特英文Ford字樣，藍底白字。由於創建人亨利·福特喜歡小動物，所以標誌設計者把福特的英文畫成一隻奔跑的小白兔樣子的圖案 。
1873年，擔任奔馳發動機廠技術部主任的哥特里布·戴姆勒，在給妻子寄去的明信片上，信手畫上了一顆三叉星以代表他當時的住處，並特別聲明：總有一天，這顆吉祥之星將會照耀我畢生的工作。1909年6月戴姆勒公司登記了三叉星做為轎車的標誌。
奔馳汽車的`標誌是現在簡化成為形似汽車方向盤的一個環形圈圍着一顆三叉星。三叉星表示在陸、海、空領域全方位的機動性，環
形圈顯示其營銷全球的發展勢頭。汽車與體育運動、旅遊、影視娛樂等密切相關，形成了一種獨特的汽車文化。你能説出與汽車有關的影視作品的名稱來嗎？
三、汽車的未來
1.新能源汽車將會大力推廣，如：油電混合汽車、純電動汽車、太陽能汽車等。
2.汽車安全標準將會更加嚴格。
3.汽車排放控制標準將會更加嚴格。
4.使用更多替代鋼、鐵的輕質材料，如高強度特種鋼、鋁合金、碳纖維等，以降低車輛自重。
5.各種電子、電控、智能裝置將越來越多地應用在汽車上，越來越智能。
同學們，汽車的未來在你們手中。只有刻苦學習科學知識才能掌握汽車製造的核心技術。希望不久的將來，你們能設計和研發出完全自主的、高品質的汽車。
