用英语介绍美国食物的演讲稿
American Food You are what you eat.Nutrition experts often use this saying to promote better eating habits.What we put in our mouths does become a part of us.But we can look at this statement another way.What we eat reflects who we are--as people and as a culture.Do you want to understand another culture?Then you ought to find out about its food.Learning about American food can give us a real taste of American culture. 你吃什么就成为什么样子营养专家经常使用这句话来倡导更好的饮食习惯，入嘴的东西确实成为我们的一部分．但我们也可以从另一个角度来看这句话，我们所吃的反映出我们自己－－不论就人或文化而言．你想了解另一种文化吗
那么你应该去认识他们的食物．认识美国食物可以让我们得知美国文化的精髓。
What is American food?At first you might think the answer is easy as pie.To many people,American food means hamburgers,hot dogs,fried chicken and pizza.If you have a sweet tooth,you might even think of apple pie or chocolate chip cookies.It's true that Americans do eat those things.But are those the only kind of vittles you can find in America? 何谓「美式食物」
乍听之下你可能认为答案容易得很。
对许多人而言，美式食物就是汉堡、热狗、炸鸡和披萨。
如果你是好吃甜食的人，你可能会想到苹果派或巧克力片饼干。
美国人确实吃这些东西，但这些就是你在美国唯一找得到的食物吗
Except for Thanksgiving turkey,it's hard to find a typically Americanfood.The United States is a land of immigrants.So Americans eat food from many different countries.When people move to America,they bring their cooking styles with them.That's why you can find almost every kind of ethnic food in America.In some cases,Americans have adopted foods from other countries as favorites.Americans love Italian pizza,Mexican tacos and Chinese egg rolls.But the American version doesn't taste quite like the original! 除了感恩节火鸡以外，挺难找到典型的美国食物。
美国是个移民之地，所以美国人吃的食物来自许多不同的国家，当人们移居美国，他们也将自己的烹调带了进来。
那也就是为什么在美国你几乎可以看到所有不同民族的食物。
在某些情况中，美国人把外国的食物视为最爱。
美国人喜爱意大利的披萨，墨西哥的玉米饼和中国的春卷，但是这些东西的美国版味道却不很道地
As with any large country,the U.S.A has several distinct regions.Each region boasts its own special style of food.Visit the South and enjoy country-style cooking.Journey through Louisiana for some spicy Cajun cuisine.Take a trip to New England and sample savory seafood dishes.Travel through the Midwest,the breadbasket of the nation,for delicious baked goods.Cruise over to the Southwest and try some tasty Tex-Mex treats.Finish your food tour in the Pacific Northwest with some gourmet coffee. 和许多大国一样，美国有数个截然不同的地区，每个地区都以自己特有的食物夸口。
走访美国南部享受乡村式的烹调；到路易斯安纳州品尝辛辣的凯郡式料理；走一趟新英格兰试尝它美味的海鲜；再到中西部「美国的面包之乡」品尝可口的烘培食品；乘船游览至西南部尝试一些好吃的墨式德州小吃，最后到太平洋西北岸，啜饮美食家的咖啡，作为美食之旅的句点。
Americans living at a fast pace often just grab a quick bite.Fast food restaurants offer people on the run everything from fried chicken to fried rice.Microwave dinners and instant foods make cooking at home a snap.Of course,one of the most common quick American meals is a sandwich.If it can fit between two slices of bread,Americans probably make a sandwich out of it.Peanut butter and jelly is an all-time American favorite. 生活在快速步调之下的美国人通常只能「很快地吃几口」。
快餐店提供赶时间的人各种食物，从炸鸡到炒饭，应有尽有。
微波炉晚餐和实时餐点使得在家烧饭省事又快速。
当然，最平常的美式速餐之一就是三明治。
任何能夹在两片土司中间的东西，美国人就可以把它作成一份三明治，花生酱和果酱更是一直都深受美国人的喜爱。
Americans on the go also tend to eat a lot of junk food.Potato chips,candy bars,soft drinks and other goodies are popular treats.Many people eat too many of these unhealthy snacks.But others opt for more healthy eating habits.Some even go all natural.They refuse to eat any food prepared with chemicals or additives. 忙碌的美国人也趋向于吃一大堆「垃圾食物」。
洋芋片、糖果、汽水和其它好吃的东西都颇受欢迎。
许多人吃了太多这类不健康的零嘴，但是其它人则选择较健康的饮食习惯，有些人甚至选择「全天然」的食物，他们拒绝吃任何有化学制品或添加物的食物。

Self-Confidence Is Essential to Success自信是成功的因素Nothing succeeds like confidence.When you are truly confident,it radiates from you like sunlight,and attracts success to you like a magnet.信就一切，当你真正自信时，它就像灿烂光一样从你身上出来，就像磁铁一样将成功吸引到你身上。
It's important to believe in yourself.Believe that you can do it under any circumstances,because if you believe you can,then you really will.The belief keeps you searching for answers,which means that pretty soon you will get them.相信自己非常重要。
要相信自己无论在任何情况下都会成功。
因为如果你相信你能做到，那么你就真的会做到。
这种信念促使你不断的去寻找答案，而不断的探索就意味着你很快就会找到答案。
Confidence is more than an attitude. It comes from knowing exactly where you are going and exactly how you are going to get there. It comes from acting with integrity and confidence.It comes from a strong sense of purpose.It comes from a strong commitment to take responsibility,rather than just letting life happen.信心不只是一种态度，它来源于你确切地知道自己要去干什么并且确切地知道怎么去干。
它来源于正直和自信地去行动。
它来源于强烈的目标感。
它来源于强烈地勇于承担责任的许诺，而不是让生命放任自流。
One way to develop self-confidence is to do the thing you fear and to get a record of successful experiences behind you.培养自信的一种方法是去做你害怕做的事情，并将它做成功。
Confidence is compassionate and understanding.It is not arrogant. Arrogance is born out of fear and insecurity,while confidence comes from strength and integrity.信心是富有同情心和善解人意的。
它一点都不傲慢自大。
傲慢是由于害怕和缺乏安全感才产生的，而信心则出于坚强的决心和诚实正直。
Confidence is not just believing you can do it. Confidence is knowing you can do it.Know that you are capable of accomplish anything you want,and live your life with confidence.信心并不是仅仅认为你可能会成功，而是确信你一定能成功。
确信你有能力实现自己的愿望，并充满信心的生活着。
Anything can be achieved through focused,determined effort and self-confidence.If your life is not what you want it to be,you have the power to change it,and you must make the changes on a moment by moment basis. Live your priorities. Live with your goals and your plan of action. Live each moment with your priorities in mind. Act with your own purpose,and you will have the life you
关于友谊的英语演讲稿，简单的带翻译
珍讲稿 今天我演讲的题目就是“珍惜粮食，从我做起。
” “锄当午，汗滴土。
谁知盘中餐，粒粒皆辛苦。
”《悯农》这首诗我们大家都太熟悉了，一粒粒粮食从播种到收割，再到加工成成品粮，至少要经过二十道工序，这中间包含了农民多少辛勤的劳动呀!可以说，每一粒粮食都浸透了农民伯伯的心血和汗水。
珍惜粮食，是我们每个公民应尽的义务，而不是说你的生活好了，你浪费得起就可以浪费。
浪费是一种可耻的行为。
即使在发达国家，节俭也被视为一种美德。
这是对劳动的尊重，也是每个人应尽的责任。

关于节假日的英文演讲稿
Just briefly on the etymology of the word “chocolate”, the word chocolate probably domes from “chocolatl”, a Spanish combination of the Maya word for “hot water” and the Aztec word for “bitter water.”咱们简单地从“巧克力”这个词的起源说起吧。
“巧克力”这个词大致起源于“chocolatl”，它是一个合成西班牙语，合成自玛雅语“热水”和阿芝特克语“苦水”。
Chocolate comes in many forms today. Regardless of the type, processing begins by extracting, fermenting, drying, and roasting the cacao seeds (also called beans), removing the shell and skin, and leaving the tasty nibs. 如今，巧克力正以多种多样的形式出现。
我们先不提它们的形状，其加工过程始于提炼、接着发酵、干燥，然后烘烤可可种子(也称为可可豆)，去壳去皮，最后留下美味的核。
There are three main forms of chocolate that one sees regularly. These are milk chocolate, dark chocolate and white chocolate. 大家通常看到的巧克力主要有三种口味，牛奶巧克力、纯巧克力和白巧克力。
Milk chocolate is a mixture of chocolate liquor, cocoa butter, milk, sugar, and flavorings. All milk chocolate made in the U.S. contains at least 10% chocolate liquor and 12% whole milk. 牛奶巧克力由巧克力乳液、可可油、牛奶、糖和其它调味材料混合而成。
美国制造的牛奶巧克力都含有至少10%巧克力乳液和12%全脂牛奶。
There are two kinds of dark chocolate. The first bittersweet and semisweet chocolate are the darkest eating chocolates and have at least 35% chocolate liquor. Sweet dark chocolate contains 15% to 35% chocolate liquor and less than 12% milk solids. It may also contain ingredients like condensed milk, cocoa butter, sugar, and vanilla. 纯巧克力主要有两种，一种是半苦半甜型巧克力，这是最纯的巧克力，至少含有35%巧克力乳液。
甜纯巧克力含有15%至35%巧克力乳液和低于12%固体牛奶。
当然，甜纯巧克力里也会含有其它成份，如炼乳、可可油、糖和香草等。
White chocolate is a blend of cocoa butter, milk, sugar, and flavorings. It contains no cocoa solids, and many people don’t consider it chocolate at all! 白巧克力是用可可油、牛奶、糖和其它调味成分混合制作而成的。
其内并不含有任何可可固体成分，因此许多人认为这根本就不是巧克力

我相信，如果大家下次再送巧克力作为情人礼物时，引经据典地讲讲巧克力的来历，肯定会让你的恋人倾倒不已
American-made chocolate and cocoa(可可) products number in the hundreds. There is a fascinating(迷人的)story behind these wonderful products. Chocolate Through the Years The story of chocolate, as far back as we know it, begins with the discovery of America. Until 1492, the Old World(指欧洲大陆，相对于美洲大陆)knew nothing at all about the delicious and stimulating flavor富有刺激性的口味) that was to become the favorite of millions. The Court of King Ferdinand and Queen Isabella got its first look at the principal ingredient(调料、原料)of chocolate when Columbus returned in triumph from America and laid before the Spanish throne(王位)a treasure trove of many strange and wonderful things. Among these were a few dark brown beans(豆)that looked like almonds(杏仁)and seemed most unpromising(无指望的). They were cocoa beans, today's source of all our chocolate and cocoa. The King and Queen never dreamed how important cocoa beans could be, and it remained for Hernando Cortez(科尔特斯), the great Spanish explorer, to grasp(把握住)the commercial possibilities of the New World offerings. Food of the Gods During his conquest of Mexico, Cortez found the Aztec Indians(阿兹特克印第安人)using cocoa beans in the preparation of the royal drink of the realm, chocolate, meaning warm liquid. In 1519, Emperor Montezuma, who reportedly drank 50 or more portions daily, served(提供，招待) chocolate to his Spanish guests in great golden goblets(高脚杯), treating it like a food for the gods. For all its regal(王室的) importance, however, Montezuma's chocolate was very bitter(苦), and the Spaniards did not find it to their taste. To make the concoction(调制品) more agreeable to Europeans, Cortez and his countrymen conceived the idea of sweetening it with cane sugar. The new drink quickly won friends, especially among the Spanish aristocracy(贵族). Spain wisely proceeded to plant cacao in its overseas colonies, which gave birth to a very profitable(利润高的) business. Remarkably enough, the Spanish succeeded in keeping the art of the cocoa industry a secret from the rest of Europe for nearly a hundred years. Chocolate Spreads to Europe Spanish monks, who had been consigned(托运) to process the cocoa beans, finally let the secret out. It did not take long before chocolate was acclaimed(受到欢迎) throughout Europe as a delicious, health-giving food. For a while it reigned(主宰)as the drink at the fashionable Court of France. Chocolate drinking spread across the Channel to Great Britain, and in 1657 the first of many famous English Chocolate Houses(作坊)appeared. The 19th Century marked two more revolutionary developments in the history of chocolate. In 1847, an English company introduced solid eating chocolate through the development of fondant(半软糖) chocolate, a smooth and velvety(光滑柔和)variety that has almost completely replaced the old coarse grained(颗粒粗糙的) chocolate which formerly dominated(统领) the world market. The second development occurred in 1876 in Vevey, Switzerland, when Daniel Peter devised a way of adding milk to the chocolate, creating the product we enjoy today known as milk chocolate. Chocolate Comes to America In the United States of America, the production of chocolate proceeded at a faster pace than anywhere else in the world. It was in pre-Revolutionary New England-1765, to be exact-that(可以肯定地说)the first chocolate factory was established in this country. During World War II, the U.S. government recognized chocolate's role in the nourishment(营养品)and group spirit(士气、团队精神) of the Allied Armed Forces, so much so that(到这样的程度以至于)it allocated valuable shipping space(分配宝贵的船舱空间)for the importation(运输) of cocoa beans. Many soldiers were thankful for the pocket chocolate bars(块、条) which gave them the strength to carry on until more food rations(配给)could be obtained. Today, the U.S. Army D-rations(美国陆军D类配给食品) include three 4-ounce chocolate bars(4盎司巧克力块)late has even been taken into space as part of the diet(食品供应、食谱)astronauts(宇航员).——————————————————————————————————————————————————————————When it comes to chocolate, order dark Dark chocolate -- but not white chocolate - may help reduce blood pressure and boost the body's ability to metabolize sugar from food, according to the results of a small study. After eating only 100 grams, or 3.5 ounces, of dark chocolate every day for 15 days, 15 healthy people had lower blood pressures and were more sensitive to insulin, an important factor in metabolizing sugar. In contrast, eating roughly the same amount of white chocolate for the same period of time did not affect either blood pressure or insulin sensitivity. This is not the first study to demonstrate potential health benefits of dark chocolate, which contains high levels of a kind of antioxidant called flavonoids. Research shows that flavonoids that can help maintain a healthy heart and good circulation and reduce blood clotting, which can lead to heart attacks and stroke. 吃巧克力时，选黑巧克力 一项小规模研究的结果表明，黑巧克力可能有助于降低血压、促进人体对食物中的糖分的代谢能力，而白巧克力则没有这些功能。
在连续15天每日食用100克或3.5盎司黑巧克力之后，15名健康的受试者的血压有所降低，而且对胰岛素更为敏感--胰岛素是促进体内糖分代谢的重要成分。
相比之下，同样在15天中食用大致相同数量的白巧克力对血压和胰岛素的敏感性并没有影响。
这已经不是有关黑巧克力可能有益健康的第一项研究。
黑巧克力富含一种叫作类黄酮的抗氧化剂，研究表明类黄酮有助于保持心脏的健康和血液循环的畅通，并减少可能导致心脏病和中风的血栓。
关于空气污染的演讲稿100字数
大家好。
今天我所演讲的题目是空气污染.空气污染是大气科学的一个新分支，它是研究在不同气象条件下，进入大气的污染物在大 气中输送、扩散稀释、转化和移除的规律及应用的科学。
本学科萌芽于20世纪20年代， 1921年英国人便进行大气扩散试验，但只是到了50年代后，现代工业的发展和城市人 口高度集中，相继出现了严重的城市或工业区污染事件，以1952年12月的伦敦烟雾事 件为例，夺去了四千多人的生命，这些促使人们对大气污染的广泛关注和研究，到60 年代便逐渐形成这门独立的新学科。
空气污染 由于人类活动或自然过程，向大气中排进了一些有害物质(称污染物)，当排入量够多(污染物浓度达一定限度)，则使原来洁净空气的品质下降，若这种情况维持时间 够长，便会对人类、动物、植物和大气中的物品产生危害和不良影响，这种大气状态称为空气污染。
组成空气污染有三个要素：污染源、污染物浓度、对人和生物有危害。
洁净大气是人类赖于生存的必要条件之一，一个人在五个星期内不吃饭或5天内不 喝水，尚能维持生命，但超过5分钟不呼吸空气，便会死亡，人体每天要吸10—12立方 米的空气。
由此可见，消除空气污染或保持污染浓度低于某个限度之下，是何等重要。
污染源与污染物向大气排入有害物质的源地称污染源，进入大气的有害物质称污染物。
大气污染源分人工源和自然源， 大气污染的危害与影响 大气污染对人类及其生存环境造成的危害与影响，已逐渐为人们所认识，归结起来有如下几个方面： ①对人体健康的危害。
人体受害有三条途径，即吸入污染空气、表面皮肤接触污染空气和食入含大气污染物的食物，除可引起呼吸道和肺部疾病外，还可对心血管系统、 肝等产生危害，严重的可夺去人的生命。
②对生物的危害。
动物因吸入污染空气或吃含污染物食物而发病或死亡，大气污染物可使植物抗病力下降、影响生长发育、叶面产生伤斑或枯萎死亡。
③对物品的危害。
如对纺织衣物、皮革、金属制品、建筑材料、文化艺术品等，造成化学性损害和玷污损害。
④造成酸性降雨，对农业、林业、淡水养殖业等产生不利影响。
⑤破坏高空臭氧层，形成臭氧空洞，对人类和生物的生存环境产生危害。
⑥对全球气候产生影响，如二氧化碳等温室气体的增多会导致地球大气增暧，导致全球天气灾害增多，又如烟尘等气溶胶粒子增多，使大气混浊度增加，减弱太阳辐射， 影响地球长波辐射，可能导致天气气候异常。
如何防治大气污染，减轻大气污染的危害与影响，构成了当今重大而紧迫的研究课题。
大气污染的防治 防治大气污染是一个庞大的系统工程,需要个人、集体、国家、乃至全球各国的共同努力，可考虑采取如下几方面措施： ①减少污染物排放量。
多采用无污染能源（如太阳能、风能、水力发电）、改革能 源结构，用低污染能源（如天然气）、对燃料进行预处理（如烧煤前，先进行脱硫）、改进燃烧技术等均可减少排污量。
另外，在污染物未进入大气之前，使用除尘消烟技 术、冷凝技术、液体吸收技术、回收处理技术等消除废气中的部分污染物，可减少进 入大气的污染物数量。
②控制排放和充分利用大气自净能力。
气象条件不同，大气对污染物的容量便不同， 排入同样数量的污染物，造成的污染物浓度便不同。
对于风力大、通风好、湍流盛、对流强的地区和时段，大气扩散稀释能力强，可接受较多厂矿企业地逆温的地区和时 段，大气扩散稀释能力弱，便不能接受较多的污染物，否则会造成严重大气污染。
因 此应对不同地区、不同时段进行排放量的有效控制。
③厂址选择、烟囱设计、城区与工业区规划等要合理，不要排放大户过渡集中，不 要造成重复迭加污染，形成局地严重污染事件发生。
④ 绿化造林，使有更多植物吸收污染物，减轻大气污染程度。
通过以上的讲解，大家知道空气对于我们人类的重要性了吧，从现在开始请大家保护环境，植树造林，创造个美好的生活环境吧
刮风可以吹散雾霾，根治还是要解决工业污染，全民齐心对抗雾霾保护环境，雾霾天出门还是要戴口罩的，普卫欣美国进口的天猫有，能有效过滤pm2.5今天，我的国旗下讲话就是这些，谢谢大家。
