可不可以让我得到一篇有关饮食的三分钟以内的英文课前演讲稿?
Food and Health I'll say something about food and health. As you know, more and more people are getting aware of the link between diet and good health. They are trying to have a balanced diet. A balanced diet should have protein,（蛋白质） fat, vitamins,（维生素） fruit and vegetables. They are good for health. However, some people still don't realise the importance of a healthier diet. They eat too much meat and sugar. As a result, they have diseases, such as cancer, heart disease and so on. It is time for us to do something now, I think. That is, we should eat the right kinds of food, and do not eat any of the unhealthy food! let us do it right away to keep health!

Fish Sticks 鱼条The fish part is usually pollock, rather healthy. The stick part seems to be the remaining 20 ingredients listed on the box, which aren't so healthy. Doctors have been advising people to eat more fish for years, because they are high in healthy fats and low in unhealthy fats compared to beef and pork. Yet when you buy processed fish products or when you order deep-fried fish from a fast-food joint, the bad starts to outweigh the good.鱼条的原材料使用，非常健康。
但是鱼条的烹饪方其含有20种有害成分，似乎么健康。
医生这些年一直建议人们多吃鱼类，因为它们比起牛肉和猪肉，含有更多健康的脂肪和较少的不健康脂肪。
当你购买加工过的鱼肉产品或在速食店里点油炸鱼时，害处立刻大于好处。
Yogurt 优酪乳Armenians in my neighborhood when I was growing up used to make their own yogurt, which is essentially milk fermented with certain bacteria. This is high in protein, calcium and vitamins and can be eaten by adults, who generally cannot digest milk well. What is sold in mainstream U.S. supermarkets under the name yogurt is really a dairy dessert loaded with sugar and processed fruit, disguised as a health food. Try plain, fat-free yogurt and add your own fruit.每当我起床时，我家附近的亚美尼亚人总是在制作他们的优酪乳，其实优酪乳就是含有有益菌的发酵牛奶。
蛋白质、钙和维他命含量丰富，通常给那些牛奶消化不良的成年人食用。
在美国主流超市销售的所谓优酪乳其实是添加糖类和加工过的水果的乳制品甜点，伪装成的健康食品。
尝试纯天然、无脂肪的优酪乳吧，你可以自己添加水果哦。
Canned Soup 罐头浓汤Soup is remarkably healthy, inexpensive and easy to make. A lunch of hardy homemade soup and bread, cooked in bulkand frozen in individual containers for the week, will cost less than a dollar a day. Canned soup, on the other hand, is a miserable concoction of salt, fat, artificial additives, preservatives, water and maybe part of a carrot. One serving typically contains 1,000 milligrams of sodium, about half your daily allowance. Save your chicken and beef bones and vegetable tops and make you own broth.显然，汤很健康，不贵，而且烹饪简单。
辛苦点，自己制作汤和面包当午餐，可以多做点汤，把一周的量分小碗装好放在冰箱，每天花费不到一美元。
罐头浓汤根本就是盐、脂肪、人工添加剂、防腐剂和水的混合物，可能还会有点胡萝卜吧。
一份罐头浓汤基本含有1000毫克的钠，几乎你一天钠摄入量的一半。
把鸡骨头、牛骨、蔬菜叶保存好，自己制作肉汤吧。
Green Tea 绿茶Green tea is widely consumed throughout Asia and is nothing short of an art form in Japan. The tea contains antioxidants and other healthful components shown in clinical studies to possibly prevent cancer, heart disease, senility and other diseases associated with aging. But most Americans don't like the taste, so what you get here is a green tea drink loaded with sugar and other additives, sold under the disguise of a health drink. Any ingredient after the words green tea on the bottle chisels away the health benefits.绿茶在亚洲非常风靡，在日本可谓是一种艺术形式。
根据临床研究表明茶叶内含有抗氧化剂和其它有益成分，可能可以预防癌症、心脏病、衰老和其它与年龄增长有关的疾病。
但是大多数美国人不喜欢这个味道，所以你在这里买到的绿茶饮品中添加了糖份和其它添加剂，还伪装成健康饮品来销售。
任何瓶子上在“绿茶”后的单词都将健康成分给剔除了。
Russet Potatoes 褐色土豆At the risk of pissing off Idaho, the Russet varieties of potatoes, with their brown skin and white flesh, are only marginally healthy to begin with. Cheap and hardy, yes, with a few nutrients, they serve some purpose as a filler. But their starch is quickly converted by the body into blood sugar, called glucose, and raises the risk of diabetes and obesity. And because they are arguably the least flavorful of the hundreds of potato varieties in the Americas, we have to do things to make them tasty. We boil and mash them and cover them in butter, or we cut them into strips, deep-fry them and cover them with salt.褐色土豆品种丰富，皮棕瓤白，本来还和营养食品沾点边，否则它应该早就滚出爱荷华州来吧。
褐色土豆便宜、耐寒，是的，有点营养，它们很管饱。
但是它们内含的淀粉在体内迅速转换成血糖，我们称之为葡萄糖，增加了罹患糖尿病和肥胖症的风险。
也因为它们是在美国几百种土豆中最不可口的那个，我们就需要把它们做的好吃点。
我们将它们煮熟、捣碎，淋上黄油，或是把它们切成条，油炸，撒上盐。
Popcorn 爆米花Popcorn today rarely resembles the healthy treat it used to be. Popcorn is, well, corn. It's high in fiber, low in calories, and contains only nominal traces of sugar, salt and fat. That changes, of course, when you add sugar, salt and fat. Microwave popcorns are the biggest offenders with their long list of ingredients to enhance flavor. Try buying popcorn kernels in bulk for pennies a serving and control the amount of salt and (real) butter. 现在的爆米花已经不像从前那么营养了。
爆米花，没错，是玉米。
玉米是高纤维、低热量，含有少量糖份、盐份和脂肪的食物。
而现在则不同了，当然，你添加了糖、盐和脂肪。
微波炉爆米花为了增加口感而使爆米花含有不少有害成分。
买点爆米花谷粒，分成几份，加入少许盐和（纯）黄油。
Sliced Bread 切片面包The most common form of bread in Americaethe mass-produced white, soft doughy bread in plastic bags with a shelf life of weeks is likely a major component of obesity and diabetes. True bread is flour and water with a pinch of salt and yeast. Packaged white bread contains flour plus sugar, corn syrup and often a dozen other ingredients. The processing creates a food product that, once eaten, is quickly converted to blood sugar, called glucose. This causes the pancreas to work overtime and ultimately destroys the organ. Even mass-produced whole wheat breads are unhealthy because they are made palatable by some evil means: the unholy trinity of sugar, salt and softening additives.在美国最普遍的就是这种大量生产的白色、松软的面包，装在塑料袋中，一周保质期，它就是造成肥胖和糖尿病的主要元凶。
正宗的面包是面粉加水，和少量盐及发酵粉制成的。
包装的白色面包含有有糖面粉、玉米糖浆，通常还添加了其他物质。
这些物质使面包一旦下肚，就迅速转化成为血糖，也就是葡萄糖。
这造成胰腺超负荷运作，最终损伤器官。
甚至是大量生产的全麦面包也不健康，为了使它们可口一些，会使用不健康的方法：添加糖类、盐份和松软剂这三个不良添加剂。
Breakfast Cereal 早餐谷物True cereals---the likes of wheat, barley, rice and oats, to name a few---are and have always been the most important food of the human race. The combination of protein, healthy fat and vitamins is unbeatable. The word cereal has been hijacked, however, by food producers who make tiny, crunchy breakfast cakes out of true cereal with the addition of sugar, corn syrup, salt, food dyes and preservatives. Try oats with raisins, or barley with 100-percent fruit spread. These are far healthier and far cheaper. 真正的谷物--像小麦、大麦、稻米和燕麦等等--对于人类来说是非常重要的食物。
它们富含了很多蛋白质、健康的脂肪和维他命。
然而“谷物”这个词被食品制造商给滥用了，他们用谷物添加糖份、玉米糖浆、盐份、食用色素和防腐剂生产出小型、松软的早餐蛋糕。
尝试用燕麦加上葡萄干，或者百分百纯果酱自制早餐。
它们肯定更健康、更便宜。
Commercial Organic 有机商品It started as a brilliant idea. Dedicated farmers would become stewards of the land, shunning the toxic chemical pesticides and fertilizers that had proliferated after WWII. They would raise food naturally, cultivate diverse crop varieties native to their soils. Animals raised for food would be treated with care and dignity. And for 30-some years, this has been the case. But organic food is so popular that its value system is in jeopardy. Big players such as Wal-Mart and Kraft want part of the profits, and their demand for cheaper production methods undermines what it means to be organic. And so we now have organic milk from caged cows force-fed organic grain. And we have organic junk food with organic ingredients flown in from around the globe, disguised as health food by virtue of the organic label.这个主意挺聪明的。
这样农民就可以变成陆上乘务员，避开在二战后开始使用的有毒化学杀虫剂和肥料。
植物会自然生长，根据自身土壤培育出各种各样的农作物。
那些用来食用的动物也会得到很好的照料。
三十年来，一直如此。
但是有机食品很受欢迎，它的价值体系也岌岌可危。
像沃尔玛和卡夫这样的大公司希望分得一杯羹，他们采用更便宜的生产方式，破坏了有机的含义。
所以我们现在喝的有机牛奶出自那些食用有机谷物长大的圈养奶牛。
我们吃着含有有机成分的有机垃圾食品，而因为它贴上有机标志，就伪装成为健康食品。
Pizza 比萨What a pity that most Americans have never eaten pizza and confuse it for the junk food advertised on television. In Italy there are laws defining pizza, which set allowances on the type of flour, tomato, mozzarella, olive oil, basil and oregano. Pizza is inherently nutritious and filling. Street corner pizza shops in Philadelphia, New York and other large cities kept close to the original idea of simple, fresh ingredients. Then came the pizza chains, which put most local shops out of business. Fresh ingredients were replaced with preservative-laden, cheap and fatty ingredients that could be mass-produced, frozen and shipped across the country. Commercial pizza is now a high-calorie, high-fat, high-sodium, low-nutrient food.多么可怜啊，大多数美国人从来没有吃过比萨，还把它和电视上广告的垃圾食品搞混。
在意大利，有关于定义比萨的法律，规定比萨由面粉、番茄、意大利干酪、橄榄油、罗勒和牛至制成。
比萨本身其实含有营养，而且管饱。
在费城、纽约和其它大型城市街角的比萨店保留了简单、新鲜的比萨制作方法。
之后出现了比萨连锁店，使得许多当地商店破产。
新鲜的食材被添加防腐剂、廉价和脂肪多多的材料所替代，这样就可以在大量生产、冷藏，运往全国各地。
比萨商品时一个高卡路里、高脂肪、高钠和低营养的食物。
如何消除食品安全的威胁
（模拟联合国大会英文演讲稿）
2Food security under threat: global response needed Climate change and commodity speculation are among the main factors threatening food security inside and outside the EU, according to a European Parliament resolution adopted on Thursday. MEPs call for urgent measures to combat food price manipulation and ensure that food production is maintained in the EU. Droughts, floods, fires and storms, on a greater scale than in the past, are reducing agricultural capacity all over the world, says the resolution. Soil and water management must be improved to prevent loss of farmland, and the Commission should monitor national climate change mitigation measures, believe MEPs. Tackling speculationMEPs criticise speculation in food commodities, agricultural raw materials and energy markets, all of which puts food security at risk. The G20 is urged to work for the convergence of market regulations by involving countries that are not part of the G20 in the fight against food price manipulation.Parliament asks the Commission to consider giving the new European Security and Markets Authority more power to prevent abuses in commodity markets. Dealing in food commodities should be limited to investors who have a genuine link with agricultural markets, MEPs believe.In addition, MEPs call on national governments not to impose curbs on exports, as these provoke greater uncertainty in the markets and disrupt world markets, and therefore have the potential to drive prices up further at global level. Helping EU farmersTo guarantee food security in the EU, a strong Common Agricultural Policy is needed, says the resolution. Declining farm incomes, caused by higher production costs to meet health, environmental and animal welfare standards, need to be urgently addressed to ensure there are farmers in the EU in the future. Market intervention tools, such as intervention and strategic stocks, must be part of the policy, says Parliament.Support for farmers in developing countriesSince agriculture is a key economic sector in the developing world, MEPs call for a larger proportion of the financial aid for this sector to be used to support more effective and sustainable farming practices. They add that land ownership should be promoted to reduce poverty and increase food security.The resolution was approved by show of hands. 3New threat to global food security as phosphate supplies become increasingly scarceA new report from the Soil Association reveals that supplies of phosphate rock are running out faster than previously thought and that declining supplies and higher prices of phosphate are a new threat to global food security. ‘A rock and a hard place: Peak phosphorus and the threat to our food security’ highlights the urgent need for farming to become less reliant on phosphate rock-based fertiliser. [1]Intensive agriculture is totally dependent on phosphate for the fertility needed to grow crops and grass. Worldwide 158 million tonnes of phosphate rock is mined every year, but the supply is finite. Recent analysis suggests that we may hit ‘peak’ phosphate as early as 2033, after which supplies will become increasingly scarce and more expensive. [2]This critical issue is missing from the global policy agenda - we are completely unprepared to deal with the shortages in phosphorus inputs, the drop in production and the hike in food prices that will follow. Without fertilisation from phosphorus it has been estimated that wheat yields could more then halve in coming decades, falling from nine tonnes a hectare to four tonnes a hectare. The current price of phosphate rock is approximately twice that of 2006. When demand for phosphate fertiliser outstripped supply in 2007\\\/08, the price of rock phosphate rose 800%.In Europe we are dependent on imports of rock phosphate, having no deposits of our own, but the geographical concentration of reserves adds further uncertainty to the future security of our sources. In 2009, 158 million metric tonnes of phosphaterock was mined worldwide. 67% of this resource was mined in just three countries - China (35%), the USA (17%) and Morocco and Western Sahara (15%). China has now restricted, and the USA has stopped, exports of phosphate. [3]Author of the report, Dr. Isobel Tomlinson, said: A radical rethink of how we farm, what we eat and how we deal with human excreta, so that adequate phosphorus levels can be maintained without reliance on mined phosphate, is crucial for ensuring our future food supplies.‘A rock and a hard place’ sets out the actions needed to close the loop on the phosphorus cycle. These include:Changing how we farmDifferent farming systems vary enormously in their reliance on mined phosphate. Organic farms are more resilient to the coming phosphorus rock ‘shock’, as it can only be used as a supplement to nutrient recycling (including crop rotations, green manures, and composting), and not as a replacement. Organic crops generally have a lower fertiliser requirement than non-organic crops, with a greater capacity to scavenge for nutrients through denser and deeper root systems.Changing what we eatEating less meat can reduce the demand for mined phosphate. This is because vegetable-based production is more efficient in its use of phosphorus then livestock production. Although different types of meat have different levels of mined phosphate demand depending on the farming system used to produce them. Meat from livestock grazed on grassland that has not been fertilised with artificial fertilisers, will perform much better than meat from livestock grazed on fields that have been, or livestock fed on grain grown using artificial fertilisers.Changing how we deal with human exretaThe report recommends a radical change in the way we treat human exreta and the need to abandon our current ‘flush-and-forget’ toilet systems in favour of Ecological Sanitation. The report also calls for a change to EU organic regulations to allow the use of human sewage – rich in ‘natural’ phosphate - on agricultural land to ensure phosphate levels are maintained. Globally only 10% of human waste is returned to agricultural soils. Urine alone contains more than 50% of the phosphorus excreted by humans.

有关仙人掌的演讲稿100字左右
我赞美仙人掌，因为仙人掌是一种具有坚持不懈精神的植物。
它对大自然索取甚少，但贡献的却是全部。
它全身是宝，多刺的外表下有柔嫩的内心。
它的茎可以入药又可食用，它有丰富的矿物质，蛋白质和许多种人体所需要的维生素和微量元素，是不可多得的绿色有机食品。
我最赞美的是它的坚持不懈的精神。
它不需要肥沃的土壤和充足的养份，也不需要湿润的气候和充沛的雨水，它能在荒无人烟的贫瘠的戈壁滩和沙漠里生长，在烈日的暴晒下也决不屈服，它坚信会有下雨的一天。
它在沙漠里默默的等待，最终得到了雨季的眷恋。
仙人掌为什么能等到雨天呢
那就是它那坚持不懈的精神。
坚持不懈的精神非常重要，它也能使人的命运发生改变。
中国着名的经济学家和教育家王亚南先生，小时候胸有大志酷爱读书，他在读中学的时候，为了争取更多的时间读书，特意把自己睡的板床的一条腿锯短半尺，成为三脚床，每天读书到深夜，疲劳时上床去睡一觉后迷糊中一翻身，床向短腿方向倾斜过去，他一下子被惊醒过来，便立即下床，伏案夜读，天天如此，从不间断。
结果他年年都取得优异成绩，被誉为班内的“三杰”之一。
由于他少年时代坚持不懈的勤奋刻苦读书，后来终于成为我国杰出的经济学家和教育家。
我们正处在学生时代，在这良好的学习环境中，更应该有仙人掌的精神，坚持不懈的努力学习，学好每一门功课，将来成为对国家、对人民有用的人才。
不要最后落得个“少壮不努力，老大徒悲伤”，悔之晚矣
坚持不懈是仙人掌的精神，我赞美仙人掌的精神，我更赞美有仙人掌精神的人。

关于生物学的演讲稿
动物故事 枯叶蝶6是其中的一个能变色避敌的高手。
枯叶蝶又叫木叶蝶，听它的名字，人们很容易联想到树木的枯枝败叶。
的确，枯叶蝶在缤纷艳丽的蝶类家族里很不起眼，但是它的隐身绝技却令人刮目相看。
它可以在不同的环境下，变换自身的颜色和形状，将自己隐蔽起来，用惟妙惟肖的伪装术蒙骗天敌，保护自身的安全。
它的前翅形状很像树叶的叶尖，后翅很像树叶的叶柄，前后翅叠在一起，看起来酷似一片树叶。
更令人惊异的是，在这片“树叶”上，还有一条条与叶脉十分相像的深褐色线条和近似于枯黄树叶的病斑，把它同树叶放在一起，几乎达到可以乱真的地步。
当枯叶蝶遇到天敌追捕时，它便迅速地落在阔叶树的枝条上，用身体紧贴枝条，双翅并拢竖起，这时候，它就像一片枯黄的树叶一样，混杂在其他树叶之中，使得天敌难以分清哪片是虫，哪片是叶，失去了追捕的对象。
当枯叶蝶在池边饮水或在树干、花朵上觅食的时候，它也会为了自身的安全，施展隐身术。
它将翅平铺在体背上，用翅面遮盖住身体，这时，它的体色会和周围环境变为一致，看起来就像是一块苔藓或菌菜。
这样，它又能骗过天敌的视线，保证了自身的安全。
