what makes life worthwhile？
How to make our life meaningful?
Some people say "life is success", also someone says "life is a tragedy". This is the result of life, successful life, not by God, not by fate, do not rely on others, but in their own as. The tragedy of life is not fate, not good, but their own incompetence, his weakness, his spiritual decadence.
Person's life should not be to live long as the sole indicator of value, it is more important to the quality of life, after the death of people miss talent have real value.
People's value lies in the self-esteem, commodity is valuable, but human dignity is priceless, when people to dignity as a commodity exchange, it will quickly lose value.
人生的价值是什么？
如何使我们的生活有意义？
有人说“人生就是成功”，也有人说“人生是一场悲剧”。这是从人生的结果来说的，成功的人生，不靠上帝，不靠命运，不靠他人，而在于自己的作为。悲剧的人生，也不是命运不好，而是自己的无能，自己的意志薄弱，自己的精神颓废。
人的一生不应该以活得多长作为价值的惟一指标，更重要的是它的生活质量，死了以后让人怀念的人才有真正的价值。
人的价值还在于自尊，商品是有价的，而人的尊严是无价的，当人们欲将尊严作为商品进行交换，那就会很快地失去价值。

中学生英语演讲稿 Friendship 友谊
Friendship
Every one of us, rich or poor, should at least have one or two good friends. My friends will listen to me when I want to speak, will wipe my eyes when I cry, will take care of me when I am sick, and my friends will go together with me side by side through this journey of life.
As students, we could share more time with our friends. The friendship in our young hearts is pure, fresh and simple. I often feel very lucky to have a lot of good friends. Especially when I had Justin as one of my best friends. Justin was my English teacher from the USA. I met him in 1996 when I was a student who could only speak very little English. Justin was a vivid young man with a bright smile on his face, and he always had his special way to make the class active and attractive. He taught us English by telling stories, playing games, singing songs, and even dancing. I could still remember very clearly that one afternoon when we fin-ished our class, we went to some other classes to sing songs for them, just like what people do in the states on Christmas Eve. It was so interesting and unforgettable. Justin was an excellent teacher, because he taught us not only how to study English well, but also the way to find out the beauty of the world and the way to be angels to others' lives. I know there was friendship and pure love in our hearts. Facing this valuable emotion neither nationality nor age was important, the real importance lay in faith, under-standing, and care. Justin is the best friend I have ever had, and I know I will cherish those days of staying together with him as the best part of my memory.
Friendship is a kind of treasure in our lives. It is actually like a bottle of wine, the longer it is kept, the sweeter it will be. It is also like a cup of tea. When we are thirsty, it will be our best choice, but when we have enough time to enjoy ourselves, it is also the most fragrant drink.
However, in this fast-developing modern society, the reality is not that. More and more people forget to enjoy the beauty of life and -the beauty of friendship. They work hard in order to gain a higher position, in the society and to earn more money for their work. Of course, we don't deny that it is important to find a bet-ter place in our lives, but we wish more and more people could pay a little more attention to themselves and their friends. All of us have to spare some time for personal lives. We have to find the chance to express our emotion and love. When staying with our friends, we can release ourselves completely. We can do whatever we want, we can laugh together, talk together, and even cry to-gether. I should say that being together with our best friends is the most wonderful moment of our lives.
As we know, we would feel lonely if we didn't even have a friend. But it doesn't mean we could depend on our friends all the time. There is a famous motto saying that “A friend is like a quilt with cotton wadding, but the real thing that keeps you warm is your own temperature.” It is really true. We have to work hard together with our friends, encourage each other and help each other. When we receive love and friendship, we should repay as much as we can.
Finally, let's pray together now that one day, all of us could find the person we want to find, and could enjoy a real beautiful friendship in our lives. Let's pray the flower of friendship be-tween our friends and us would always bloom brightly in our hearts

Soy food good for women
Women 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, reced 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 proced 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 ration 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。”
G. 英语演讲稿 关于如何准备四级考试
所谓的四级，无来非就是一个测源试你所学英语的程度如何。那考得都是平时的积累，在四级之前的几天提高很少的。你这一点要弄清楚！但是，在四级前几天，你应该做几套真题，不是为了有什么提高，二是要看看题型，心里边有个打算，知道什么地方对于自己比较容易，而哪些地方比较难。
其实真要做的，是要看几篇书面表达，背住其中的什么关联词啦，结构啦，好的句子啦！你在写作时候完全可以用上的。
这就是我想要说的，希望你可以受益！要在平时多多努力哦！~~~~~~~·

Good morning/evening/afternoon, ladies and gentlemen :
Today, my speech is about talents,in my opionion, talents are indispensable in nowadays society. as is known to all that the fight among countries is actually the fight among talents.
First, i'd like to define the word"talent" in my idea, a talent is one person who is good at or expertised in some or multiple areas. nowadays, as the world developing goes on , if one country want to rank top or do a good job in the world, the country must have many talents.for example, china, the biggest developing country in the world, in the past 100 years, is always invaded by other countries, why ,the reason is that china at that time had not so many talents. if they had anti-intrusion leader talents in the war, needless to say,they would have beat those big powers.if they had talents in weapons manufacturing, nodody dares to provoke us.however, nowadays, it's a totally different situation, china has become powerfulin all over the world, why ? because there are many talents serving the country, the civilians become more and more literated.more and more people go to university,more and more people come to receive further ecation. so what is that in return,talents in army protect our country from invasion, talents in commerce help make our economy keep in improving, talents in aerospace make the world see chinese manned spacecraft flying. talents in sports make china rank the first in the olympic games……
To sum up, talents will play a more and more impoetant role in the world, if one country intends to flourish, he must foster talents as many as they can ,that's all,thank you.
I. 高分速求与爱国有关的英文演讲稿，大学四级水平。
数学是理工科学生必备的基础。很多学生在高中时认为数学是最难学的，到了大学里，一旦发现本专业对数学的要求不高，就会彻底放松对数学知识的学习，而且他们看不出数学知识有什么现实的应用或就业前景。但大家不要忘记，绝大多数理工科专业的知识体系都建立在数学的基石之上。例如，要想学好计算机工程专业，那至少要把离散数学（包括集合论、图论、数理逻辑等）、线性代数、概率统计和数学分析学好；要想进一步攻读计算机科学专业的硕士或博士学位，可能还需要更高的数学素养。同时，数学也是人类几千年积累的智慧结晶，学习数学知识可以培养和训练人的思维能力。通过对几何的学习，我们可以学会用演绎、推理来求证和思考的方法；通过学习概率统计，我们可以知道该如何避免钻进思维的死胡同，该如何让自己面前的机会最大化。所以，大家一定要用心把数学学好，不能敷衍了事。学习数学也不能仅仅局限于选修多门数学课程，而是要知道自己为什么学习数学，要从学习数学的过程中掌握认知和思考的方法。
二十一世纪里最重要的沟通工具就是英语。有些同学在大学里只为了考过四级、六级而学习英语，有的同学仅仅把英语当作一种求职必备的技能来学习，甚至还有人认为学习和使用英语等于崇洋媚外。其实，学习英语的根本目的是为了掌握一种重要的学习和沟通工具。在未来的几十年里，世界上最全面的新闻内容，最先进的思想和最高深的技术，以及大多数知识分子间的交流都将用英语进行。因此，除非你甘心做一个与国际脱节的人，英语学习是至关重要的。在软件行业里，不但编程语言是以英语为基础设计出来的，最重要的教材、论文、参考资料、用户手册等资源也大多是用英语写就的。学英语绝不等于崇洋媚外。中国正在走向世界，中国需要学习西方的先进思想和先进科学技术，学好英语才是真正的爱国。
很多中国留学生的英语考试成绩不错，也高分考过四级、六级、托福，但是留学美国后上课时却很难听懂课程内容，和外国同学交流时就更加困难。我们该如何学好英语呢？既然英语是最重要的沟通工具，那么，最重要的学习方法就是尽量与实践结合起来，不能只“学”不“用”，更不能只靠背诵的方式学习英语。读书时，大家尽量阅读原版的专业教材（如果英语不够好，可以先从中英对照的教材看起），并适当地阅读一些自己感兴趣的专业论文，这可以同时提高英语和相关专业的知识水平。其次，提高英语听说能力的最好方法是直接与那些以英语为母语的外国人对话。现在有很多在中国学习和工作的外国人，他们中的不少人为了学中文，很愿意与中国学生对话、交流，这是很好的学习机会。此外，大家不要把学英语当作一件苦差事，完全可以用有趣的方法学习英语。例如，可以多看一些名人的对话或演讲，多看一些小说、戏剧甚至漫画。初学者可以找英文原版的教学节目和录像来学习，有一定基础的则应该看英文电视或电影。看一部英文电影时，最好先在有字幕的时候看一遍，同时查考生词、熟悉句式，然后在不加字幕的情况下再看一遍，仅靠耳朵去听。听英文广播也是很好的练习英文听力的方法，大家每天最好能抽出半小时到一小时的时间收听广播并尽量理解其中的内容，有必要的话还可以录下来反复收听。在互联网上也有许多互动式的英语学习网站，大家可以在网站上用游戏、自我测试、双语阅读等方式提升英语水平。总之，勇于实践、持之以恒是学习英语的必由之路。
信息时代已经到来，大学生在信息科学与信息技术方面的素养也已成为他们进入社会的必备基础之一。虽然不是每个大学生都需要懂得计算机原理和编程知识，但所有大学生都应能熟练地使用计算机、互联网、办公软件和搜索引擎，都应能熟练地在网上浏览信息和查找专业知识。在二十一世纪里，使用计算机和网络就像使用纸和笔一样是人人必备的基本功。不学好计算机，你就无法快捷全面地获得自己需要的知识或信息。
最后，每个特定的专业也有它自己的基础课程。以计算机专业为例，许多大学生只热衷于学习最新的语言、技术、平台、标准和工具，因为很多公司在招聘时都会要求这些方面的基础或经验。这些新技术虽然应该学习，但计算机基础课程的学习更为重要，因为语言和平台的发展日新月异，但只要学好基础课程（如数据结构、算法、编译原理、计算机原理、数据库原理等）就可以万变不离其宗。有位同学生动地把这些基础课程比拟为计算机专业的内功，而把新的语言、技术、平台、标准和工具比拟为外功。那些只懂得追求时髦的学生最终只知道些招式的皮毛，而没有内功的积累，他们是不可能成为真正的高手的。
虽然我一向鼓励大家追寻自己的兴趣，但在这里仍需强调，生活中有些事情即便不感兴趣也是必须要做的。例如，打好基础，学好数学、英语和计算机的使用就是这一类必须做的事情。如果你对数学、英语和计算机有兴趣，那你是幸运儿，可以享受学习的乐趣；但就算你没有兴趣，你也必须把这些基础打好。打基础是苦功夫，不愿吃苦是不能修得正果的。
