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.
人生的價值是什麼？
如何使我們的生活有意義？
有人說「人生就是成功」，也有人說「人生是一場悲劇」。這是從人生的結果來說的，成功的人生，不靠上帝，不靠命運，不靠他人，而在於自己的作為。悲劇的人生，也不是命運不好，而是自己的無能，自己的意志薄弱，自己的精神頹廢。
人的一生不應該以活得多長作為價值的惟一指標，更重要的是它的生活質量，死了以後讓人懷念的人才有真正的價值。
人的價值還在於自尊，商品是有價的，而人的尊嚴是無價的，當人們欲將尊嚴作為商品進行交換，那就會很快地失去價值。

中學生英語演講稿 Friendship 友誼
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

F. 幫我找一篇關於健康的英語演講稿，三分鍾左右，大學四級水平
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.
據美國研究人員報告，兒童時期經常吃豆類食品的女性患乳腺癌的風險較小。另一組研究人員則向美國癌症研究協會提出，一周吃幾次魚的男性患結腸癌的幾率較小。
這兩項研究進一步證明了飲食對於防癌的作用。癌症防治專家認為，在所有種類的癌症中，多達三分之二都是由吸煙、節食及缺乏鍛煉等不健康的生活方式造成的。
美國全國癌症研究所和夏威夷大學的研究人員發現，在5歲至11歲時經常吃豆腐、味噌等豆類食品的女性患乳腺癌的幾率要低58%。至於豆類食品為什麼可以防癌還不清楚，不過大豆中所含的名叫異黃酮的化合物具有雌性激素的作用。
另一項研究表明，一周吃魚至少五次的男性患結腸癌的風險要比那些一周都吃不到一次魚的男性低40%。
很多魚類中所富含的Omega-3脂肪酸能夠抑制環氧化酶2的活性。環氧化酶2會引起發炎，這可能會刺激腫瘤的生長。
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.
研究人員提醒，如果你已步入中年，發現自己的記憶力不如從前，那麼你得小心體重了。研究表明，超重的人記憶測試的得分要比較瘦的人低。
研究發現，體重偏大的中年人今後患老年痴呆症的可能性較大。
研究報告在《神經學》期刊上發表，研究人員推斷，心血管疾病及糖尿病的高發現象可以解釋其中的原因。此外，脂肪細胞所產生的物質，如瘦體激素，對大腦有直接影響。
此項研究將調查對象的智力與體重指數進行了對比。體重指數指的是身高和體重之間的比例，主要用來衡量一個人是否偏胖或肥胖。體重指數為25或25以上的人偏胖，達到30或30以上的人則為肥胖。
研究人員還對體重指數和認知功能間的關系進行了研究，他們在法國對2223位年齡在32歲至62歲間的健康男女進行了認知測試。
研究發現，體重指數越大，認知測試的得分越低。其中一項"單詞記憶"的測試結果表明，在16個單詞中，體重指數為20的人平均能記住9個，而體重指數為30的人平均只能記住7個。
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) 本周一公布的一項大規模英國調查表明，睡眠不足的人死於心臟病的幾率是睡眠充足者的兩倍多。
目前其中的原因尚不清楚，但研究人員稱，睡眠不足會導致血壓升高，從而增大患心臟病和中風的風險。
一項針對1萬名政府職員、長達17年的跟蹤調查表明，每晚睡眠時間從七個小時減少到五個小時或更少的人因各種原因而死亡的幾率是睡眠正常者的1.7倍，而且死於心血管疾病的風險也增加了1倍多。
沃里克大學醫學院的心血管葯物學教授弗朗西斯哥•卡普西奧在英國睡眠學會在劍橋召開的一年一度的研討會上說，這一研究成果揭示了忙碌的現代生活中潛在的危險。
他在接受記者采訪時說：「三分之一的英國人以及超過40%的美國人每晚的睡眠時間常常達不到五個小時，所以這個問題不可小視。」
此前有調查發現輪班及睡眠中斷會對健康產生潛在威脅。但卡普西奧及其同事的這項調查則首次揭示了睡眠時間長短與死亡率之間的關系。該調查由英國政府和美國基金提供資助。
該調查對年齡在35歲至55歲之間的人在1985年至1988年以及1992年至1993年兩個階段的睡眠模式進行了探究，並對這一人群截至2004年的死亡率進行了追蹤。
調查還考慮到了調查對象的初始年齡、性別、是否吸煙喝酒、體重指數、血壓及膽固醇指標等其它可能的風險因素。
卡普西奧說，睡眠時間過長也可能導致如抑鬱症及癌因性疲乏等其它健康問題。
他說：「就預防而言，我們的研究結果表明，每晚睡眠時間持續保持在七小時左右最益於身體健康。」
G. 英語演講稿 關於如何准備四級考試
所謂的四級，無來非就是一個測源試你所學英語的程度如何。那考得都是平時的積累，在四級之前的幾天提高很少的。你這一點要弄清楚！但是，在四級前幾天，你應該做幾套真題，不是為了有什麼提高，二是要看看題型，心裡邊有個打算，知道什麼地方對於自己比較容易，而哪些地方比較難。
其實真要做的，是要看幾篇書面表達，背住其中的什麼關聯詞啦，結構啦，好的句子啦！你在寫作時候完全可以用上的。
這就是我想要說的，希望你可以受益！要在平時多多努力哦！~~~~~~~·

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. 高分速求與愛國有關的英文演講稿，大學四級水平。
數學是理工科學生必備的基礎。很多學生在高中時認為數學是最難學的，到了大學里，一旦發現本專業對數學的要求不高，就會徹底放鬆對數學知識的學習，而且他們看不出數學知識有什麼現實的應用或就業前景。但大家不要忘記，絕大多數理工科專業的知識體系都建立在數學的基石之上。例如，要想學好計算機工程專業，那至少要把離散數學（包括集合論、圖論、數理邏輯等）、線性代數、概率統計和數學分析學好；要想進一步攻讀計算機科學專業的碩士或博士學位，可能還需要更高的數學素養。同時，數學也是人類幾千年積累的智慧結晶，學習數學知識可以培養和訓練人的思維能力。通過對幾何的學習，我們可以學會用演繹、推理來求證和思考的方法；通過學習概率統計，我們可以知道該如何避免鑽進思維的死胡同，該如何讓自己面前的機會最大化。所以，大家一定要用心把數學學好，不能敷衍了事。學習數學也不能僅僅局限於選修多門數學課程，而是要知道自己為什麼學習數學，要從學習數學的過程中掌握認知和思考的方法。
二十一世紀里最重要的溝通工具就是英語。有些同學在大學里只為了考過四級、六級而學習英語，有的同學僅僅把英語當作一種求職必備的技能來學習，甚至還有人認為學習和使用英語等於崇洋媚外。其實，學習英語的根本目的是為了掌握一種重要的學習和溝通工具。在未來的幾十年裡，世界上最全面的新聞內容，最先進的思想和最高深的技術，以及大多數知識分子間的交流都將用英語進行。因此，除非你甘心做一個與國際脫節的人，英語學習是至關重要的。在軟體行業里，不但編程語言是以英語為基礎設計出來的，最重要的教材、論文、參考資料、用戶手冊等資源也大多是用英語寫就的。學英語絕不等於崇洋媚外。中國正在走向世界，中國需要學習西方的先進思想和先進科學技術，學好英語才是真正的愛國。
很多中國留學生的英語考試成績不錯，也高分考過四級、六級、托福，但是留學美國後上課時卻很難聽懂課程內容，和外國同學交流時就更加困難。我們該如何學好英語呢？既然英語是最重要的溝通工具，那麼，最重要的學習方法就是盡量與實踐結合起來，不能只「學」不「用」，更不能只靠背誦的方式學習英語。讀書時，大家盡量閱讀原版的專業教材（如果英語不夠好，可以先從中英對照的教材看起），並適當地閱讀一些自己感興趣的專業論文，這可以同時提高英語和相關專業的知識水平。其次，提高英語聽說能力的最好方法是直接與那些以英語為母語的外國人對話。現在有很多在中國學習和工作的外國人，他們中的不少人為了學中文，很願意與中國學生對話、交流，這是很好的學習機會。此外，大家不要把學英語當作一件苦差事，完全可以用有趣的方法學習英語。例如，可以多看一些名人的對話或演講，多看一些小說、戲劇甚至漫畫。初學者可以找英文原版的教學節目和錄像來學習，有一定基礎的則應該看英文電視或電影。看一部英文電影時，最好先在有字幕的時候看一遍，同時查考生詞、熟悉句式，然後在不加字幕的情況下再看一遍，僅靠耳朵去聽。聽英文廣播也是很好的練習英文聽力的方法，大家每天最好能抽出半小時到一小時的時間收聽廣播並盡量理解其中的內容，有必要的話還可以錄下來反復收聽。在互聯網上也有許多互動式的英語學習網站，大家可以在網站上用游戲、自我測試、雙語閱讀等方式提升英語水平。總之，勇於實踐、持之以恆是學習英語的必由之路。
信息時代已經到來，大學生在信息科學與信息技術方面的素養也已成為他們進入社會的必備基礎之一。雖然不是每個大學生都需要懂得計算機原理和編程知識，但所有大學生都應能熟練地使用計算機、互聯網、辦公軟體和搜索引擎，都應能熟練地在網上瀏覽信息和查找專業知識。在二十一世紀里，使用計算機和網路就像使用紙和筆一樣是人人必備的基本功。不學好計算機，你就無法快捷全面地獲得自己需要的知識或信息。
最後，每個特定的專業也有它自己的基礎課程。以計算機專業為例，許多大學生只熱衷於學習最新的語言、技術、平台、標准和工具，因為很多公司在招聘時都會要求這些方面的基礎或經驗。這些新技術雖然應該學習，但計算機基礎課程的學習更為重要，因為語言和平台的發展日新月異，但只要學好基礎課程（如數據結構、演算法、編譯原理、計算機原理、資料庫原理等）就可以萬變不離其宗。有位同學生動地把這些基礎課程比擬為計算機專業的內功，而把新的語言、技術、平台、標准和工具比擬為外功。那些只懂得追求時髦的學生最終只知道些招式的皮毛，而沒有內功的積累，他們是不可能成為真正的高手的。
雖然我一向鼓勵大家追尋自己的興趣，但在這里仍需強調，生活中有些事情即便不感興趣也是必須要做的。例如，打好基礎，學好數學、英語和計算機的使用就是這一類必須做的事情。如果你對數學、英語和計算機有興趣，那你是幸運兒，可以享受學習的樂趣；但就算你沒有興趣，你也必須把這些基礎打好。打基礎是苦功夫，不願吃苦是不能修得正果的。
