产品介绍英语演讲稿篇一:产品介绍英语演讲稿公司及产品讲稿列位亲爱的家人(朋友或伙伴们):大伙儿上午(下午)好!我是大漠紫光超级荣幸今天由我来介绍一下咱们公司及产品(打招呼表示感激)(塑造产品价值,突出产品独特卖点,引发强烈爱好)列位亲爱的伙伴们在进入主题之前我可不能够和大伙儿先做一下友好的互动(能够),请问大伙儿咱们每一个人都专门期望让自己变得更年轻长寿对不对(对),咱们每一个人都期望让自己远离疾病与痛楚是不是(是的),咱们每一个人都专门想吃到营养全面最健康的食物对吗(对的)!可是我想讲的是现代科技尽管如此发达,人们的生活水平取得了显著提高,可是现代人的死亡率却在慢慢呈现年轻化,普遍化的趋势。
咱们来看以下的一组数据:几乎99%的人都存在亚健康,50%以上的人患有前列腺疾病,30%以上的人视力有问题,死亡年轻化的具体表现就再于死神不只垂青于年老的,而正将魔爪伸向成功的年轻人,死亡的名单中即有没钱、贫困的、也有有钱的、出名的,有权的成功人士,咱们来一起的试探一下,什么缘故有如此的悲剧发生?什么缘故死亡会呈现愈来愈年轻化的趋势,而不是老年化呢?按理说,那些富有和成功的人,本来更应该有资格多享受人一辈子。
比一样人能够活的更长寿,更健康,因为他们能够消费的起高级化妆品,保养品,买得起高级滋补保健品,那么一个人什么缘故会生病呢?有钱人什么缘故寿命会越短,下面咱们来听听营养保健专家们的观点:针对那个问题,专家们做出了以下良好的建议:他们说一个人要想活的健康,远离疾病,就要做到,少抽烟,少饮酒,不吃或少吃油腻、膨化、烧烤、油炸类食物,要注意营养均衡,维持多运动,心怀踊跃心态,多吃新鲜蔬菜水果,生活维持有规律,工作有目标,维持少睡早起。
大伙儿说专家们总结的体会,对咱们有无帮忙,好不行?(专门好,太好了)。
答案固然是好了,简直太好了!可是咱们都明白,那个世界上,没有人是全能的,任何人都有他不能办到的事,专家也一样,大家说对吗?(对的)因此,单纯从理论上讲,专家们的观点理论,确实够权威专业,可是真正到咱们每一个人,开始实施它的时候,却又很难办取得,具体表此刻以下的客观缘故:咱们无法掌控,专家也无法掌控,那确实是现代社会,因为过度开发致使了人类生活的大环境,受到了严峻破坏,处处是摩天大楼,从而对地心造成了极大的压力,因此火山海啸,泥石流在全世界频繁出没,地下因为常年过度开采煤矿,将地心挖空,致使地球失去平稳力,丛林受到了过度的砍伐,从而致使生态被破坏,过度建筑从而造成尘埃污染,汽车尾气排放,工业烟囱向天空排放化学气体,致使天空空气造成污染、水污染、环境污染致使田地中的果蔬污染,食物为了延长保质期,为了好卖,从而人为的添加了化学剂,人工色素,防腐剂,甜蜜素,致使饮料营养流失减少,人们的居住环境,因为装修工,人为的以次充好,将有毒的油漆及涂料涂在室内的墙上,从而造成咱们赖以生存的环境空气污染,现代人,因为久居温室里,远离阳光,缺少晒太阳,从而致使躯体虚弱,抗击力下降,免疫力下降,常吹空调,长期在空调下生活工作,就会得空调病,食物污染的案例,真是太多了,在此举几个具代表性的例子供大伙儿检讨:像暖锅底料,商家为了盈利,在暖锅底料中加了化学剂,牛奶中加了三聚氰胺,主食馒头中加了漂白剂,大米中掺了增白剂,玉米中加了糖精,火腿肠中掺了致癌物,肉中加了瘦肉精,注了水,莲藕表面摸了漂白粉,豆腐中掺了米粉、石灰粉,扎啤中掺了化学剂,鱼吃了避孕药,鸡、鸭、鹅、猪、牛在大型圈养场,服用了大量生长激素。
冷冻人,通常指的是人体冷冻保存技术,是一种尝试将人体或人体部分在极低温下保存,以期在未来能够复活或治疗疾病的技术。
这种技术目前主要应用于医学领域,尤其是器官保存和再生医学。
以下是一些关于冷冻人原理的基本概念:
1. 低温保存:冷冻人的基本原理是将人体或器官降温至极低温度,通常是液氮温度(-196°C),以减缓细胞活动和代谢过程,从而延缓组织衰老和细胞损伤。
2. 细胞休眠:在极低温下,细胞内的水分会形成冰晶,导致细胞活动几乎完全停止,进入一种休眠状态。
这种状态可以持续很长时间,而不会导致细胞死亡。
3. 防止冰晶损伤:为了防止冰晶对细胞结构造成损伤,冷冻过程中通常会使用抗冻剂(如二甲亚砜)来替换体内的水分,这些抗冻剂可以降低冰点,减少冰晶的形成。
4. 长期保存:通过上述方法,人体或器官可以在极低温下长期保存,理论上可以达到数十年甚至更长时间。
5. 未来复活:支持者认为,随着未来医学技术的发展,可能能够复活这些冷冻保存的人体或器官,用于治疗疾病或延长寿命。
然而,冷冻人技术目前还面临着许多科学和伦理上的挑战,包括如何确保冷冻过程中的细胞存活率、如何防止冰晶损伤、如何在未来复活冷冻人体等问题。
此外,这一技术在社会和伦理层面也引发了广泛的讨论和争议。
因此,尽管冷冻人技术具有潜在的医学价值,但它仍然是一个高度争议性的研究领域。

1 55. Personalize your ideas Personalize: to present one’s ideas in human terms that relate in some fashion to the experience of the audience.
* People are interested in people. Sample speech with commentary Cryonics by Jayne Richter 1. The time is now. Imagine your mother or father has suffered a heart attack. Deprived of its vital blood supply, a part of their heart is dying. Or imagine your grandmother or grandfather lying nearly motionless in their nursing home bed. Advanced age, complicated by pneumonia, is about to end their lives. Or imagine a close friend has just entered the hospital with a massive systemwide infection. AIDS has left their body ravaged by multiple diseases. Begin with examples to get attention because they relate the topic to the audience. 2
2. For most people, these circumstances would herald the end of life. Today’s medicine can no longer help them. But all of you may be able to meet again in the far future. Does this should like science fiction? Perhaps. But it may one day be possible. How? Through the process of cryonics. The speaker gives two questions to interest the audience, get the audience involved,. Then reveal the topic.
3. Cryonics is the process of freezing human beings after death in hope that medical science will be able to revive them in the future. Intrigued by the prospect of being cryonically frozen, I’ve spent some time researching the subject of cryonics. After reading dozens of newspaper and magazine articles, I would like to give you a brief overview of the history, methods, and future of cryonics. Let’s start with the development of cryonics. The speaker defines cryonics, build credibility, and previews the main points to be discussed of the speech.
4. Although the idea of freezing people is relatively new, the notion of preserving them is old. In the 1770s, for example, Ben Franklin wrote he wanted to be “immersed in a cask of Madeira wine, ’til that time when he could be recalled to life.” It was not 3
to be ,but Franklin’s dream lived on to be revived in our time as cryonics. The speaker moves to her first main point. Use historical examples to introduce cryonics.
5. Cryonics has been a staple (话题) of science fiction novels, the plot device in movies such as Austin Powers and Sleepers, and the subject of countless newspapers and magazine articles. Until 1964, however, cryonics remained firmly in the realm of fiction. It was at this time that physics professor Robert Ettinger argued in his book The Prospect of immortality that cryonics was indeed possible. Three years later, on January 12, 1967, 73-year-old James H Bedford became the first human being to be cryonically frozen. Give details like names and dates to add depth to explanation.
6. Ever since Bedford was frozen, cryonics has steadily increased in popularity. Currently there are four cryonic institutions in the United States-two in California and one each in Michigan and Arizona. So far 80 people have been cryonically frozen from around the world, and another estimated 800 people have signed up to be frozen when they die. 4
Their aim is to remain frozen in a state of suspended animation (活气,生气)---perhaps for centuries---in the hope that medical science will be able to revive them in the future at a time when cures(治愈) exist for all of today’s diseases and when restoration to full function and health is possible. End the speaker’s first main point.
7. So you’re probably wondering how will they do it? How does cryonics work? Use questions to let the audience know she is moving to second main point.
8. Currently, when a person who has signed up to be cryonically suspended dies, a specific procedure, which was outlined in the book Cryonics: Reaching for Tomorrow, must be carried out. First, before death, an individual must decide whether to have his or her entire body frozen or just the head. If the whole body is to be frozen, it must be preserved upon death. Immediately after death---ideally within a matter of minutes---the patient is connected to a heart-lung machine and chemicals such as glucose (葡萄糖)and heparin (肝素,一种抗凝血药)are circulated(循环) with the
