跪求：三分钟英语演讲稿
环保问题: (1) As is apparently revealed in the pie charts above, forty-eight percent of people surveyed have never heard of the International No Motor Vehicle Day while fifty-seven percent are willing to give up driving on such a day. What is betrayed in the pie charts is most thought-provoking. The implied meaning of the pie charts is both disappointing and exciting. On the one hand, much necessary work still needs to be done with respect to environmental protection. The public ignorance of relevant environmental protection results from inadequate and limited popularity of environmental protection knowledge by relevant government departments at different levels. Since environmental protection is an international issue, we must constantly introduce the advanced and practical practice in other countries to our general public. Only in this way can we promote environmental protection in China. On the other hand, the enhancement of the public awareness of environmental protection is a welcome development. Over the past years, as people’s living standard improves, people attach more importance to the quality of their life. They have a better understanding of the relationship between environment and their daily life. As a result, they are more interested in following positive international models. In sum, we have got a mixed feeling toward the very fact revealed in the pie charts. In my view, necessary measures should be immediately taken to ensure a nice environment. First of all, government departments at all levels must play a more active role in popularizing international experience and practice of environmental protection. What’s more, the general public should be encouraged to participate more actively in environmental protection. Only in this way can we live in a healthy and harmonious environment.

二. 演讲部分：在我们享受的时候懂得珍惜Cherish what we are enjoyingIt is a report about the new planet which holds possibility for life.这是一篇关于发现了一颗有生命可能性的星球的报告。
It shows that European astronomers have discovered a new planet, they name it Gliese 581 c.说欧洲天文学家们发现了一颗新的星球，代号为“Gliese 581C”。
It is about 20.5 light years from our earth. They estimated the planet's average temperature at between 0 and 40 degrees Centigrade. It is orbiting the red dwarf star, Gliese 581.它距地球约20.5光年。
他们估计它的平均温度约在0℃～40℃之间。

(3)打好环保比赛、创建绿色北京 尽管2008北京奥运会离我们还有3年之遥，但有一项规模宏大的特殊比赛已经拉开了序幕。
这场比赛的参加者并非来自世界各国的体育选手，而是身处北京的每一位公民，比赛的场所就是我们身边的街区小巷。
我想大家已经想到了我所说的这项特殊比赛，这就是创建绿色北京、保护美好环境。
那么在这场环保大赛中，我们究竟要与谁一比高低
是繁华现代的洛杉矶、风光迷人的悉尼、还是古老神奇的雅典
都不是
比赛的对手就是我们自己，就是我们自身淡漠的环保意识。
几年前有幸在美国加州度过的一段时光，既让我享受了那里宜人的环境，更让我领略了当地人民高度的环保意识。
每当说到城市环保，我的眼前总会浮现出加州那蔚蓝的天空、明媚的阳光、碧绿的草地以及嬉戏在树枝间的松鼠、彩蝶和百灵鸟。
记得刚到美国时，常去爸爸工作的美国地质调查局玩耍，每次均能看到许多人骑自行车上下班，而其中一位满头白发的骑车老人，引起了我的好奇。
我问爸爸，那个爷爷为什么总骑车上班，是不是没钱买车
爸爸笑道：没钱买车
嘿，说出来吓死你，他可是世界上顶级的大科学家。
要论钱，他可以买一个车队呢。
那他咋不买车呢
骑车多累呀
他有车，但平时除非下雨或购物，一般不去开。
在美国有许多人都是环保主义者，为了节约能源和减少汽车尾气对大气的污染，他们用实际行动倡导人们尽量少开车。
而我们所居住的这座美国城市，还特别将每年的5月19日定成了'骑车上班日'，以支持和宣传这种有效的环保行为。
后来，我还在经常的搭车出行中获知了他们的另一件环保趣事：在美国的许多州，政府为了鼓励大家多坐公交车或几人合用一辆车，以节省能源和缓解交通压力，在城市内一些主干道路上开辟有专门的'钻石车道'，只有乘坐了二人或二人以上的车辆才从此通过。
美国人民这种自觉的环保意识和政府有效的环保措施使我从内心对他们充满了敬佩。
并深刻地影响了我的环保理念。
回国后，常常有人问我：美国好吗
我总会脱口而出：确实好
最好的是环境。
说句真心话，回国三、四年，美国那边同学和老师的面孔已经逐渐模糊，但加州那宜人的自然环境，却每每清晰地浮现在我的眼前，成为我最深的记忆和期盼故地重游的缘由，也成了我心目中北京环境的蓝图。
2008奥运会为我们倡导和实施北京的环保提供了契机，北京能否有朝一日也拥有象加州那样美丽的环境
答案是肯定的。
但需要我们以真正的环保之心和切实的环保行动去一步一步地实现。
从现在开始，如果每一位有车的朋友一星期可以少开一、两次车，每个让家长用车接送的同学一周能主动让家长少接送一两趟而改乘公车或骑自行车，我们就会有拥有更多的蓝天……。
只要我们每一位北京市民都能够自觉的从身边的环保小事做起，加州的蓝天、白云和绿草地就会在北京安家，美国的松鼠、彩蝶和百灵鸟就会来北京落户。
涓涓细流可以汇成滔滔江海，片片绿叶能够造就莽莽森林。
只要我们每一位北京市民都拿起手中的环保之笔，在我们所处的街头巷尾，为北京这幅美丽而古老的画卷添上自己的一抹绿色，就能使北京掩映在绿色的海洋中。
让我们一起行动起来，用我们集体的力量来打赢这场环保之赛，向全世界展现一块最大的金牌，这就是绿色北京、精彩奥运。
Win Competition of Environment Protection for Beijing Although the 2008 Olympics are still three years away, another special competition has already started in Beijing. This time, the competitors are not the athletes from all over the world, but the people living in Beijing. The special competition is not held in a stadium, but in every street and every corner of Beijing. I suppose some of you may have already guessed what the special competition is. Yes, it is the competition of protecting our environment and creating a green Beijing for the 2008 Olympic Games. Someone may ask who is our rival in this competition? The modern Los Angeles, the charming Sydney, or the historic Athens? No, none of them. The real rival is ourselves. It is our bad habits of neglecting to protect environment in our daily life. Several years ago, I was very lucky to have an opportunity to live in the United States for about two years. I not only enjoyed the beautiful environment there, but also appreciated the American people's active way of protecting their environment. Now, whenever the environment protection is mentioned, a beautiful view of California will arise in my mind: white clouds flying across the blue sky, green grassplot sprinkled with colorful flowers and small animals playing happily among the trees. I remember that at the beginning of my coming to America, I often went to my father's working place, the United States Geological Survey, to have fun. Each time I found a lot of people riding bicycles to their offices. Among the cyclists, an old man with white hair attracted my attention. Curiously, I asked my father, Why does the old man ride his bike to work every day? Doesn't he have enough money to buy a car? Father laughed, No, not because of money. Actually, he is one of the greatest scientists in the world. He can afford to buy a motorcade if he likes. He is just an environmentalist and usually doesn't drive unless going shopping, or in bad weather. In America, there are a lot of environmentalists, who actively protect their environment. For example, in Palo Alto city we are living now, there is even a bicycle-to-work day on May 19th every year to encourage people to decrease air pollution caused by cars. Later, I also learnt another interesting fact of environment protection there. In some states of America, in order to decrease air pollution, save energy and reduce traffic jams, state governments encourage people to take buses to work or to share a car among several people. They even set special diamond lanes in some main streets, which are only for the vehicles with 2 or more people. The positive actions of American people and the effective measures the American government takes in environment protection fully won my respects and deeply affected my consciousness in environment protection. When I was back in China, people often asked me: What do you think of America? I always bolt out: Wonderful, especially the beautiful environment. Frankly speaking, after several years, the faces of my American teachers and friends have gradually faded away from my mind, but the blue sky, green grass and lovely animals in California often arise in my mind, and became my dream of visiting there again. The 2008 Olympics provide us with the opportunity to publicize and practise environment protection in Beijing. Is it possible for Beijing to Is it possible for Beijing to become as beautiful as California? The answer is yes, but the dream needs every Beijing citizen's full support and active moves to accomplish. From now on, if every student who is driven to school can take bus or ride bicycle to school once a week, if every car owner goes to work in a car pool once a week, we can make a difference. If everyone can actively protect the environment in our daily life, the blue sky, green grass and lovely animals in California will appear in Beijing. Tiny streams can combine into a vast ocean, small trees can together be an immense forest. Beijing is often described as a beautiful and aged picture. If every Beijing citizen adds a trait of green on the picture, the whole Beijing will become an ocean of green. Let us unite together to win the competition of environment protection in Beijing, and present the world a big gold medal. That is Green Beijing, Great Olympics
求一篇英文的关于麦当劳的演讲稿，内容主要包括起源，发展及对美国人的影响，1000字左右
McDonald's In 1955, a man named Raymond Kroc entered a partnership with two brothers named McDonald. They opened a popular restaurant in Califor-nia which sold food that was easy toprepare and serve quickly. Hamburgers, French fries and cold drinks were the main food there.Kroc opened similar eating places under the same name,McDonald's, and they were an instant success. He later took over the company, and today it is one of the most famous and successful fast-food restaurants in America and the world. Why was his idea so successful? Probably the most important reason was that his timing was right. In the ]950s,most married women stayed home to keep house and take care of their children. In the 1960s, many women returned to the work place. This meant that they had less time and energy for housework and preparation of meals, so they depended more on TV dinners and fast-food restaurants. Single parents also have little time to spend in the kitchen. People living alone also depend on this type of food, since cooking for one is often more trouble than it is worth. Fast-food is not part of all Americans lives. Another trend of the 1960s, sometimes called the back-to-nature movement,influenced many people to avoid food that was packaged and processed. This preference for natural food continues to this day. From the success of Raymond Kroc's fast-food business,we can say that social and economic trends influence where and what we eat. 麦当劳 1955年，一位名为雷蒙德·克劳克的人与两位名为麦当劳的兄弟合伙，在加州开了一家颇受欢迎的小餐馆，销售制作方便服务快捷的食物。
那里的主打食品是汉堡、炸薯条和冷饮。
克劳克用同样的名字—一麦当劳开了几家类似的餐厅，迅速获得了成功。
后来他接管了这个公司，今天它成为美国和世界最有名、最成功的“快餐”厅之一。
他的想法为什么会如此成功呢?也许最重要的原因是因为他时机正好。
20世纪50年代，大多数已婚妇女呆在家里做家务、照顾孩子。
而在60年代，许多妇女回去工作。
这就意味着她们做家务、准备食物的时间、精力减少了，因此她们更多地依赖于“电视晚餐”和快餐店。
单亲家庭中父母也很少有时间花在厨房里。
独自居住的人也依赖于这种食物，因为一个人做饭经常太麻烦，不值当费那功夫。
快餐并不是所有美国人生活的一部分。
20世纪60年代还有另一种有时被成为“返璞归真”运动的趋势，影响了很多人，他们避免食用经过包装和加工的食物。
这种对天然食物的青睐一直持续到今天。
从雷蒙德·克劳克快餐生意的成功中，我们可以说社会和经济趋势会影响我们就餐的地点和食物的选择。
关于时间管理的英语演讲稿
时间的宝贵(The Value of Time) A proverb says,Time is money. But in my opinion, time is even more precious than money. Why? Because when money is spent, we can earn it back. However, when time is gone, it will never return. This is the reason why we must value time.Collected by www．ii63·com It goes without saying that the time for our study and work is unusually limited. Hence, even an hour is extremely precious. We should make full use of our time to do useful things. As a student,I must make efforts to engage in my study so as to serve our nation and people in the future. But it is a pity that there. are a lot of people who do not know the importance of time. They do not realize that wasting time is equal to wasting a part of their valuable life.collected by II63·com In a word, we should form the good habit of saving time. Do not put off what can be done today till tomorrow. Laziness will not only bring us failure but also lead us to the road of poverty. 关于珍惜时间的英语演讲稿时间的宝贵 谚语说，“时间就是金钱。
”依我看，时间比金钱更可贵。
为什么? 因为钱花了，还可挣回来。
时间流逝了，将会一去不复返。
这就是我们应当珍惜时间的道 不消说，我们用于学习和工作的时间是有限的，因此，哪怕是一小时也是极其宝贵的。
我们应当充分利用时间去做有用的事情。
作为一名学生，我要努力专心学习以便将来为国为民服务。
遗憾的是，还有许多人并不知道时间的重要，他们还没有意识到浪费时间就等于浪费他们宝贵的生命。
一句话，我们应养成节约时间的好习惯。
不要把今天能完成的事拖到明天。
懒惰不仅导致失败，而且还会使我们贫困。

帮我找一篇关于健康的英语演讲稿，三分钟左右，大学四级水平
Soy food good for womenWomen who ate soy regularly as children have a lower risk of breast cancer, American researchers report. And men who eat fish several times a week have a lower risk of colon cancer, a second team of researchers have told the American Association for Cancer Research. The studies add to a growing body of evidence about the role of diet in cancer. Cancer experts now believe that up to two-thirds of all cancers come from lifestyle factors such as smoking, diet and lack of exercise. The US National Cancer Institute and researchers at the University of Hawaii found that women who ate the most soy-based foods, such as tofu and miso, when aged 5 to 11, reduced their risk of developing breast cancer by 58 per cent. It was not clear how soy might prevent cancer, though compounds in soy called isoflavones have estrogen-like effects. A second study showed that men who ate fish at least five times a week had a 40 per cent lower risk of developing colorectal cancer compared with men who ate fish less than once a week. Many kinds of fish are rich in omega-3 fatty acids, which interfere with the cyclooxygenase-2 or COX-2 enzyme. COX-2 affects inflammation, which may play a role in tumour growth.据美国研究人员报告，儿童时期经常吃豆类食品的女性患乳腺癌的风险较小。
另一组研究人员则向美国癌症研究协会提出，一周吃几次鱼的男性患结肠癌的几率较小。
这两项研究进一步证明了饮食对于防癌的作用。
癌症防治专家认为，在所有种类的癌症中，多达三分之二都是由吸烟、节食及缺乏锻炼等不健康的生活方式造成的。
美国全国癌症研究所和夏威夷大学的研究人员发现，在5岁至11岁时经常吃豆腐、味噌等豆类食品的女性患乳腺癌的几率要低58%。
至于豆类食品为什么可以防癌还不清楚，不过大豆中所含的名叫异黄酮的化合物具有雌性激素的作用。
另一项研究表明，一周吃鱼至少五次的男性患结肠癌的风险要比那些一周都吃不到一次鱼的男性低40%。
很多鱼类中所富含的Omega-3脂肪酸能够抑制环氧化酶2的活性。
环氧化酶2会引起发炎，这可能会刺激肿瘤的生长。
If you're middle-aged and your memory's not what it used to be, check the bathroom scale, researchers warned, suggesting overweight people tend to score more poorly on tests of memory than their thinner peers do. The findings suggest that a heavier weight in middle age may mean a higher risk of dementia later in life. Reporting in the journal Neurology, the researchers speculated that higher rates of cardiovascular disease or diabetes might help explain the link. But it's also possible that substances produced by fat cells, such as the hormone leptin, have direct effects on the brain. The study compared mental abilities to body mass index (BMI), a measurement of weight in relation to height used to define overweight and obesity. A BMI of 25 or more indicates overweight, and 30 or more is obese. The study also investigated the relationships between BMI and cognitive function in 2,223 healthy men and women between the ages of 32 and 62 in France through the use of four cognitive tests. The study found a higher BMI was associated with lower cognitive test scores. Results from a test involving word memory recall show people with a BMI of 20 remembered an average of nine out of 16 words, while people with a BMI of 30 remembered an average of seven out of 16 words. 研究人员提醒，如果你已步入中年，发现自己的记忆力不如从前，那么你得小心体重了。
研究表明，超重的人记忆测试的得分要比较瘦的人低。
研究发现，体重偏大的中年人今后患老年痴呆症的可能性较大。
研究报告在《神经学》期刊上发表，研究人员推断，心血管疾病及糖尿病的高发现象可以解释其中的原因。
此外，脂肪细胞所产生的物质，如瘦体激素，对大脑有直接影响。
此项研究将调查对象的智力与体重指数进行了对比。
体重指数指的是身高和体重之间的比例，主要用来衡量一个人是否偏胖或肥胖。
体重指数为25或25以上的人偏胖，达到30或30以上的人则为肥胖。
研究人员还对体重指数和认知功能间的关系进行了研究，他们在法国对2223位年龄在32岁至62岁间的健康男女进行了认知测试。
研究发现，体重指数越大，认知测试的得分越低。
其中一项单词记忆的测试结果表明，在16个单词中，体重指数为20的人平均能记住9个，而体重指数为30的人平均只能记住7个。
People who do not get enough sleep are more than twice as likely to die of heart disease, according to a large British study released Monday.Although the reasons are unclear, researchers said lack of sleep appeared to be linked to increased blood pressure, which is known to raise the risk of heart attacks and stroke.A 17-year analysis of 10,000 government workers showed those who cut their sleep from seven hours a night to five or less faced a 1.7-fold increased risk of death from all causes and more than double the risk of cardiovascular death.The findings highlight a danger in busy modern lifestyles, Francesco Cappuccio, professor of cardiovascular medicine at the University of Warwick's medical school, told the annual conference of the British Sleep Society in Cambridge.A third of the population of the UK and over 40 percent in the US regularly sleep less than five hours a night, so it is not a trivial problem, he told reporters.Previous research has highlighted the potential health risks of shift work and disrupted sleep. But the study by Cappuccio and colleagues, which was supported by British government and US funding, is the first to link duration of sleep and mortality rates.The study looked at sleep patterns of participants aged 35-55 at two points in their lives - 1985-88 and 1992-93 - and then tracked their mortality rates until 2004.The results were adjusted to take account of other possible risk factors such as initial age, sex, smoking and alcohol consumption, body mass index, blood pressure and cholesterol.Cappuccio said it was possible that longer sleeping could be related to other health problems such as depression or cancer-related fatigue.In terms of prevention, our findings indicate that consistently sleeping around seven hours per night is optimal for health, he said.(Agencies) 本周一公布的一项大规模英国调查表明，睡眠不足的人死于心脏病的几率是睡眠充足者的两倍多。
目前其中的原因尚不清楚，但研究人员称，睡眠不足会导致血压升高，从而增大患心脏病和中风的风险。
一项针对1万名政府职员、长达17年的跟踪调查表明，每晚睡眠时间从七个小时减少到五个小时或更少的人因各种原因而死亡的几率是睡眠正常者的1.7倍，而且死于心血管疾病的风险也增加了1倍多。
沃里克大学医学院的心血管药物学教授弗朗西斯哥•卡普西奥在英国睡眠学会在剑桥召开的一年一度的研讨会上说，这一研究成果揭示了忙碌的现代生活中潜在的危险。
他在接受记者采访时说：“三分之一的英国人以及超过40%的美国人每晚的睡眠时间常常达不到五个小时，所以这个问题不可小视。
”此前有调查发现轮班及睡眠中断会对健康产生潜在威胁。
但卡普西奥及其同事的这项调查则首次揭示了睡眠时间长短与死亡率之间的关系。
该调查由英国政府和美国基金提供资助。
该调查对年龄在35岁至55岁之间的人在1985年至1988年以及1992年至1993年两个阶段的睡眠模式进行了探究，并对这一人群截至2004年的死亡率进行了追踪。
调查还考虑到了调查对象的初始年龄、性别、是否吸烟喝酒、体重指数、血压及胆固醇指标等其它可能的风险因素。
卡普西奥说，睡眠时间过长也可能导致如抑郁症及癌因性疲乏等其它健康问题。
他说：“就预防而言，我们的研究结果表明，每晚睡眠时间持续保持在七小时左右最益于身体健康。

怎样去响音“保护母亲河行动”
写成演讲稿或调查报告
为了响应团省委的号召，我们现代教育技术学院举办了“保护母亲河”社会实践活动，我们的实践地点是山西省忻州市静乐县。
我们的母亲河——汾河流经这里。
我们沿汾河两岸徒步前进，沿途清除汾河流域白色污染垃圾，向沿途村民宣传保护母亲河知识，对汾河流域生态环境进行调查。
现将调研情况报告如下： 一、母亲河（汾河）的概况 汾河是山西最大的河流，全长710公里,也是黄河的第二大支流。
汾河是一条养育了三晋儿女的母亲河。
二、母亲河存在的主要问题 1、水质受污染严重。
据了解汾河两岸居民常发现母亲河的水“变味”了。
沿河居民的生活污水排放也威胁到居民饮用水卫生安全。
汾河水已变的浑浊不堪。
2、母亲河流域植被生态受到威胁。
整个汾河流域的森林覆盖率低，生态系统稳定性差，生态功能差，水源涵养和调节能力下降，抵御自然灾害能力不足，非法占用耕地现象严重，母亲河植被的保护与管理形势依然严峻。
3、沿河居民的保护母亲河的意识不足。
我们沿途向村民宣传保护母亲河知识，大部分群众对保护母亲河的活动表示赞同。
但仍有不少的群众不以为然，参与保护的意识不够。
一大部分人虽然有保护的潜意识，但仍依赖政府来保护母亲河，而自己参与保护的意识不足。
从沿河两岸随处可见的生活垃圾、无序地排放污水等现象，可见两岸居民对保护母亲河的意识很不足。
三、保护“母亲河”的几点建议 1、加大宣传。
动员全社会力量投入到治理和保护“母亲河”活动。
相关部门要充分利用“保护母亲河”活动的品牌，联合有关执法部门、宣传部门，利用报纸、电视、广播等新闻宣传媒体，大力宣传治理和保护“母亲河”的重要性、紧迫性，大力宣传《中华人民共和国水法》、《中华人民共和国防洪法》、《环境保护法》、《林业法》、《矿产资源法》等法律法规。
对一切违法、违规破坏生态环境的行为要给予舆论上曝光，形成全社会共同为治理保护母亲河出一份力量、献一份爱心、尽一份责任的氛围。
2 、加大执法力度。
治理和保护“母亲河”，涉到水利、国土、公安、交通、工商、环保、建设等众多部门，常因为多头管理、各自为政、执法不严，造成管理和监督的不落实、不到位，“多家管，没管好”的情况确实存在。
为此，应在市保护母亲河的统一协调下，各有关部门要明确任务，落实责任，整合执法力量，通力协作，联合执法，综合治理。
要加大执法力度，严厉打击各种破坏生态环境的违法行为。
3、以科学发展观为指导，制定和落实好治理、保护“母亲河”规划。
