汽车演讲稿篇一：私家车的影响演讲稿
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.
汽车演讲稿篇二：汽车知识讲稿
一、 汽车的发明与发展
（一）汽车诞生之前，马车就是人类最好的陆上交通工具。
（二）卡尔?奔驰 就是现今德国大名鼎鼎的“奔驰”汽车公司的第一代祖宗，戴姆勒--奔驰汽车公司的创始人之一。 他被称为“现代汽车之父”。
他在英国人瓦特发明蒸汽机和德国人奥托发明内燃机的基础上，开始思考把发动机按在车上，代替马。
? 1878年开始研究新型内燃机。
? 1879年首次研制成功火花塞点火内燃机。
? 1882年开始尝试把发动机安装在三轮车上。
? 1885年他的三轮车研制成功。
? 1886年1月29日获得专利，被公认为世界第一辆实用的汽车。 ? 德国另一为工程师哥特里布·戴姆勒也同时造出了一辆用1.1
马力汽油发动机作动力的四轮汽车。
? 1883年，他发明成功了世界第一台高压缩比的内燃发动机，成
为现代汽车发动机的鼻祖。
? 1926年，奔驰和戴姆勒公司合并成为戴姆勒-奔驰公司，生产“梅
塞德斯-奔驰”牌汽车
进入20世纪以后，汽车不再仅是欧洲人的天下了，特别是
美国的亨利· 福特。1908年福特“T”型车问世，福特流水式
生产线建成，开始了崭新的汽车生产方式。初期的汽车还有使用实心木轮的，后来使用了自行车所用的辐条式的铁制车轮，外套实心橡胶轮。这种实心轮当车速超过16km／h时，车就会跳起来，使司机和乘客颠簸得无法忍受。英国人邓洛普发明了用于自行车的充气轮胎后不久，1895年，法国的米其林兄弟就制造出了用于汽车的充气轮胎，使汽车行驶的舒适性大大提高。
（三）中国汽车发展历史
1.无汽车工业时期
2.创建阶段（1949～1965年）
3.成长阶段（1966～1980年）
4.全面发展阶段（1981～2000年）
5.飞速发展阶段（2000年～至今）
二、 汽车品牌与文化
福特汽车的标志是采用福特英文Ford字样，蓝底白字。由于创建人亨利·福特喜欢小动物，所以标志设计者把福特的英文画成一只奔跑的小白兔样子的图案 。
1873年，担任奔驰发动机厂技术部主任的哥特里布·戴姆勒，在给妻子寄去的明信片上，信手画上了一颗三叉星以代表他当时的住处，并特别声明：总有一天，这颗吉祥之星将会照耀我毕生的工作。1909年6月戴姆勒公司登记了三叉星做为轿车的标志。
奔驰汽车的`标志是现在简化成为形似汽车方向盘的一个环形圈围着一颗三叉星。三叉星表示在陆、海、空领域全方位的机动性，环
形圈显示其营销全球的发展势头。汽车与体育运动、旅游、影视娱乐等密切相关，形成了一种独特的汽车文化。你能说出与汽车有关的影视作品的名称来吗？
三、汽车的未来
1.新能源汽车将会大力推广，如：油电混合汽车、纯电动汽车、太阳能汽车等。
2.汽车安全标准将会更加严格。
3.汽车排放控制标准将会更加严格。
4.使用更多替代钢、铁的轻质材料，如高强度特种钢、铝合金、碳纤维等，以降低车辆自重。
5.各种电子、电控、智能装置将越来越多地应用在汽车上，越来越智能。
同学们，汽车的未来在你们手中。只有刻苦学习科学知识才能掌握汽车制造的核心技术。希望不久的将来，你们能设计和研发出完全自主的、高品质的汽车。
