Math is about the existence of the natural sciences are controversial. Some people think that math is a human sciences, but also someone think math is a branch of philosophy is a logical part of the study. However, math and natural sciences are closely related to the relationship between is indisputable. And natural sciences have different humanities, social sciences and engineering
自然科學
自然科學是研究大自然中有機或無機的事物和現象的科學。自然科學包括天文學、物理學、化學、地球科學、生物學等等。關於數學是否是自然科學存在著爭議。有人認為數學是一門人文科學，也有人認為數學是哲學的分支，是邏輯學的一部分。但數學與自然科學之間息息相關的關系是無可爭辯的。與自然科學不同的還有人文學、社會科學和工程學

㈡ 關於科學與自然的英語作文

China has a very long and brilliant history, whose people are so friendly and hospitable. But I am wondering why some people pay such little attention to the environment and nature. In many places of the countryside, rivers have become stinking sewers and brooks have disappeared. Heaps of garbage obstructs the scarce flow of dirty water. The grounds are littered with plastic bottles and bags. People are cutting down trees even though it is illegal. In some towns, rubbish is hidden behind walls. Garbage cans are often of little use, making cleaners must rush all day long and also by night to clean the rubbish.
我覺得這行望採納(∩_∩)O~

科學家的英語作文

[科學家的英語作文]Thomas Edison and Benjamin FranklinThomas Edison lived from 1847 to 1931; he is most famous for inventing the light bulb. Benjamin Franklin lived from 1706 to 1790, and he is credited with discovering electricity.Both men were inventors, and both were born in the United States. As children, both Franklin and Edison had limited schooling.Both inventors are said to have self-taught themselves mostly through their love of reading.Franklin and Edison were both interested in electricity, and I think they would have had a lot to talk about if they had ever met face-to-face.They were different too though. They lived in very different times. While Benjamin Franklin discovered electricity. Edison's inventions and discoveries all required electrical currents: light bulbs, microphones, phonographs, fluoroscopes, etc.我好想成為科學家，因為如果我是一名科學家，我就可以創造出許多有用的東西，科學家的英語作文。

如果我是科學家，我會研製出一種手槍，這種手槍和我們平常見到的不一樣，它可以自動收集空氣轉換成子彈，還可模敏螞以自動定位瞄準目標，警察叔叔利用這把手槍就可以快速抓到犯罪分子，更好維護社會安全。

如果我是科學家，我會製造出一種可以折疊起來的房子，它可以放進背包，甚至可以裝進口袋，這樣就可以幫助那些災後沒有房子住的兒童，也可以讓我們出外旅遊變得方便，走到哪裡就可以帶到哪裡。

如果我是科學家我就會製造出一種可以放出冷、熱兩用的機器，拿仿在炎熱的夏天可以把熱氣吸進機器里，這樣夏天就不覺得炎熱，在寒冷的冬天會把冷氣收集到機器里，冬天不會覺得寒冷，中學生作文《科學家的英旦埋語作文》。

利用這種機器，既改善了我們的生活環境，又能節約能源。

如果我是科學家，我會發明一種可以在天上飛、地上跑、水裡游的汽車，這樣我們就不需要這么多種交通工具，減少停放交通工具的麻煩，節約土地。

如果我是科學家，我會發明一種食品，只要吃了這種食品就可以連續三天都不會飢餓，這樣我就可以幫助那些災區急需食品的人們。

如果長大了我當上科學家，我就會發明或發現很多東西來提高我們國家高科技水平，為我們的學習、工作、生活帶來許多方便，所以我現在要好好學習，積累生活和社會知識，爭取長大以後當上偉大的科學家，做一個有益於社會和人民的人。

科學家是怎樣煉成的？當然不是憑空出現的，他們的出現必然是有一個或多個因素導致的。

首先，要是一個很愛動腦，並且對科學極其熱愛的人，這是一切因素的承載者，是為基礎，是成為一個科學家的前提。

其次，要有一定的資金。

資金——作為科學研究的物質保證，起著不可替代的作用，它也決定著一個科不家能否完成他自己的實驗，能否成為一個有名的科學家。

第三，也是最重要的，這個人要有堅定不移的意念，為科學研究獻身的意念，還要有耐心，因為進行科學研究的過程必定是枯燥的，只有耐得住寂寞的人才能完整，完美地完成研究。

然後，就是作為一位科學家，一定要有在一定要有豐富的想像力，只有有了想像力，才能夠想像到以前從未出現過的東西，然後進行研究，最終完成發明。

試想，如果愛迪生沒有在大腦中完成為電燈的設想，那麼，又從何而來的那一千零一次的努力，從何而來我們現在的燈火通明。

所以想像力也是十分重要的。

可見，一個人之所以能夠成為發明家，不是只要勤奮這一項就足夠的，而是多種因素集中在一個人的身上而煉就的。

科學實驗為題的英語作文80字

In ancient times, many people believed the earth was a flat disc. Well over 2,000 years ago; the ancient Greek philosophers were able to put forward o good arguments proving that it was not. Direct observations of heavenly bodies were the basis of both these arguments. First, the Greeks knew that ring eclipses of the moon the earth was beeen the sun and the moon, and they saw that ring these eclipses, the earth's shadow on the moon was always round, they realized that this could be true only if the earth was spherical, If the earth was a flat disc, then its shadow ring eclipses would not be a perfect circle; it would be stretched out into a long ellipse. The second argument was based on what the Greeks saw ring their travels. They noticed that the North Star, or Polaris, appeared lower in the sky when they traveled south, in the more northerly regions, the North Star appeared to them to be much higher in the sky. By the way, it was also from this difference in the apparent position of the North Star that the Greeks first calculated the approximate distance around the circumference of the earth, a figure recorded in ancient documents says 400.000 stadium, that's the plural of the world stadium. Today, it's not known exactly what length one stadium represents, but let's say it was about 200 meters, the length of many athletic stadiums. This would make the Greeks estimate about ice the figure accepted today, a very good estimate for those writing so long before even the first telescope was invented.

My grandmother became a widow in 1970. Shortly after that, we went to the animal shelter to pick out a puppy to keep her pany. Grandma decided on a little terrier that had a reddish-brown spot above each eye. Because of these spots, the dog was promptly named Penny.Grandma and Penny quickly became very attached to each other, but that attachment grew much stronger about three years later when Grandma had a stroke. Grandma could no longer work, so when she came home from the hospital, she and Penny were constant panions.After her stroke, it became a real problem for Grandma to let Penny in and out because the door was at the bottom of a flight of stairs. So a mechani *** using a rope and pulley was installed from the back door to a handle at the top of the stairs. Grandma just had to pull the handle to open and close the door. If the store was out of Penny's favorite dog food, Grandma would make one of us cook Penny browned beef with diced potatoes in it. I can remember teasing my grandmother that she loved that dog better than she loved her family.As the years passed, Grandma and Penny became inseparable. Grandma's old house could be filled to the brim with people, but if Grandma went to take her nap, Penny walked along beside her and stayed by her side until she awoke. As Penny aged, she could no longer jump up on the bed to lay next to Grandma, so she laid on the rug beside the bed. If Grandma went into the bathroom, Penny would hobble along beside her, wait outside the door and acpany her back to the bed or chair. Grandma never went anywhere without her faithful panion by her side.The time came when both my grandmother and Penny's health were failing fast. Penny couldn't get around very well, and Grandma had been hospitalized several times. My uncle and I lived with Grandma, so Penny was never left alone, even when Grandma was in the hospital. During these times, Penny sat at the window looking out for the car bringing Grandma home and would excitedly wait at the door when Grandma came through it. Each homeing was a grand reunion beeen the o.On Christmas Day in 1985, Grandma was again taken to the hospital. Penny, as usual, sat watching out the window for the car bringing Grandma home. Two mornings later when the dog woke up, she couldn't seem to work out the stiffness in her hips as she usually did. The same morning, she began having seizures. At age fifteen, we knew it was time. My mother and aunt took her to the veterinarian and stayed with her until the end.Now the big dilemma was whether to tell Grandma while she was still in the hospital or wait. The decision was made to tell her while she was in the hospital because when we pulled up at the house, the first thing Grandma would look for was her beloved Penny watching out the window and then happily greeting her at the door. Grandma shed some tears but said she knew that it had to be done so Penny wouldn't suffer.That night while still in the hospital, Grandma had a massive heart attack. The doctors frantically worked on her but could not revive her. After fifteen years of loving panionship, Grandma and Penny passed away within a few hours of each other. God had it all worked out – Penny was waiting at door when Grandma came Home. 我的祖母成了寡婦， 1970 .不久，我們去畜舍挑小狗陪她.奶奶決定對小獵犬了紅褐色場以上，每眼.由於這些景點中，狗被及時命名為竹. 奶奶及竹很快成了非常重視對方，但扣押的增長十分強勁，約三年後，當外婆了，終年65歲.外婆不能再工作，所以當她回家，從醫院，她和竹不斷的同伴. 之後她中風，它成為一個真正的問題，奶奶讓竹中出，因為大門在底層的樓梯.這樣一個機制，用繩子和滑輪裝置，從後門句柄在頂部的樓梯.奶奶剛拉把手打開和關閉車門.如果商店是出一分錢的狗喜愛的食物，奶奶將使我們其中庫克竹餡料牛肉與洋蔥，土豆而已.我記得取笑我姥姥說，她很喜歡狗比她愛她的家人. 隨著歲月的推移，奶奶及竹成為密不可分的.奶奶的老房子可填至7.6人，但是如果奶奶去把她的行動，竹走過身旁待在她身旁，直到她醒來.至於竹歲，她再也無法跳起來於床上，以奠定未來阿媽，讓她放在地毯旁邊的床上.如果奶奶走進浴室，將竹蹣跚沿她旁邊，等候在門外，並陪同她回到床上或椅子.奶奶沒任何未經她的忠實伴侶的身旁. 時間來到時，無論是我的祖母和篙生均未能迅速.竹不能惟我獨尊很好，奶奶曾多次住院.我叔叔和我住同奶奶，讓竹從來孑然一身，連奶奶時，在醫院昏迷了.在這些時候，竹坐在窗口看出去，為使汽車奶奶回家就會興奮等候在門口時，奶奶進來.每頌是一個規模宏大的團聚兩者之間. 聖誕節當日，在1985年，外婆又被送往醫院.竹...

2 How to learn English wellLearning English just like learning any other language, is hard work so my first advice is to spend much time practicing using English every day. Besides, we should listen to the teacher and take notes carefully in class. Go over what is learnt regularly and finish doing our homework carefully. Listen to English radio programmes, read English stories and newspapers, watch English films and TV programmes ,keep a diary in English and attend English debbates and speech contests. If we make mistakes, correct them at once and try not to make the same mistakes. What's more, we should look up new words in the dictionary before class and prepare each lesson carefully before class. I believe if we work hard and have good ways of learning English, we will learn English well.學習英語就象學習其他語言一樣是艱辛的。

因此我的第一個建議是每天花多點時間練習使用英語。

除此之外，我們應該上課認真聽講、記筆記。

定期復習所學內容，認真做作業。

聽英語廣播，讀英語故事和報紙，看英語電影和電視節目，用英語寫日記，參加英語討論和演講比賽。

如果我們犯錯誤，就要立刻改正，盡力下次不要犯同樣的錯誤。

而且，我們在上課前要查字典，認真准備每節課。

我相信如果我們努力學習、有好的學習方法，我們會學好英語的。

希望對你有幫助，祝：學業有成，更上一層樓

生物與環境平衡的危機

The history of life on earth has been a history of interaction between living things and their surroundings. To a large extent, the physical form and the habits of the earth’s vegetation and its animal life have been molded by the environment. Considering the whole span of earthly time, the opposite effect, in which life actually modifies its surroundings, has been relatively slight. Only in the present century has one species man acquired significant power to alter the nature of his world.

During the past quarter century this power has not only become increasingly great but it has changed in character. The most alarming of all man’s assaults upon the environment is the contamination of air, earth, rivers, and sea with dangerous and even lethal materials. This pollution is for the most part irrecoverable. In this now universal contamination of the environment, chemicals are the sinister partners of radiation in changing the very nature of the world the very nature of its life. Chemicals sprayed on croplands or forests or gardens lie long in soil, entering into living organisms, passing from one to another in a chain of poisoning and death. Or they pass mysteriously by underground streams until they emerge and combine into new forms that kill vegetation, sicken cattle, and work unknown harm on those who drink from once pure wells. "Man can hardly even recognize the devils of his own creation," as a scientist has said.

It took hundreds of millions of years to proce the life that now inhabits the earth. Given time not in years but in millennia life adjusts, and a balance has been reached. But in the modern world there is no time.

The rapidity of change follows the impetuous pace of man rather than the deliberate pace of nature. Radiation is now the unnatural creation of man’s tampering with the atom. The chemicals are the synthetic5 creations of man’s inventive mind, having no counterparts in nature.

To adjust to these chemicals would require not merely the years of a man’s life but the life of generations. And even this, were it by some miracle possible, would be futile, for the new chemicals come from our laboratories in an endless stream; almost five hundred annually find their way into actual use in the United States alone. Among them are many that are used in man’s war against nature. Since the mid 1940’s over 200 basic chemicals have been created for use in killing insects, weeds, and other organisms described as "pests."

It is not my contention that chemical insecticides must never be used. I do contend that we have put poisonous and biologically potent chemicals indiscriminately into the hands of persons largely or wholly ignorant of their potentials for harm. We have subjected enormous numbers of people to contact with these poisons, without their consent and often without their knowledge. I contend, furthermore, that we have allowed these chemicals to be used with little or no advance investigation of their effect on soil, water, wildlife, and man himself. Future generations are unlikely to forgive our lack of concern for the integrity of the natural world that supports all life.

地球上生命的歷史一直就是一部生物與其環境相互作用的歷史。在很大程度上，地球上動植物的形態以及習性都是由外部環境所塑造的。考慮到地球上生命存在的整個時間，相反作用，即生命對其周圍環境的實際改變作用，卻相對很小。只有在當前這個世紀(指20世紀)才有一個物種--人類，獲得了強大的力量，改變了其所生存的世界的自然狀態。

在過去的1/4世紀中，這種力量不僅日趨強大，而且其性質也發生了變化。在人類破壞環境的種種行為中，最令人擔憂的是人類向大氣、土壤、河流以及海洋中排放危險甚至致命物質，而當今這種污染在很大程度上是無法挽救的。在當今這種對環境的普遍污染中，化學製品與輻射狼狽為奸，改變著地球的自然狀態，也就是改變著地球上生命的自然狀態。噴灑到農田、森林或者花園里的化學物質長期滯留於土壤中，滲入有機體內，並彼此相傳，形成了一個中毒與死亡的鏈條。化學物質還神秘地通過地下水傳遞，最終以新的形式出現並結合，使植物毒死，牲畜害病，並使飲用一度純凈的井水的人遭受了不明之害。正如一位科學家所言：“人類甚至對自己創造的惡魔都不認識。”

地球歷經了許多億年才創造了棲息其上的生命。經過了一定時間--不是以若干年計而是以若干千年計的時間--生命開始適應環境，並形成了一種與環境的平衡。但是在現代世界中，時間這一因素已經沒有了。

環境改變的速度不再順從大自然從容不迫的節奏，而是順從人類急切匆匆的步伐。輻射是當今人類通過支配原子而得到的一種非自然的創造物。化學製品則是人類有發明創造力的頭腦創造出來的合成物，在自然界本無相應的東西。

為了適應這些化學製品，人類需要付出的時間不會只是一個人一生的時間，而是幾代人的時間。而即使這樣，就算出現奇跡成為可能，這種適應也是徒勞的，因為新的化學製品從我們的實驗室中源源不斷地湧出。僅在美國，每年就有大約500種化學製品投入使用，其中許多是用於人類對自然的戰爭中。從20世紀40年代中期起，人類已經創造了200多種基本化學製品用來消滅昆蟲、野草以及其他所謂的“有害生物”。

我不是說人類決不能使用化學殺蟲劑。我要說的是，我們不分青紅皂白地將這些有毒的、具有強大生物功能的化學製品，交給了那些對這些製品的潛在危害基本上或者完全無知的人去使用。我們使眾多的人接觸這些有毒物質，卻沒有徵得他們的同意，並常常將他們蒙在鼓中。我還要說的一點是，我們允許使用這些化學製品，卻事先很少或者根本沒有調查它們對土壤、水、野生生物以及人類自身造成的影響。我們缺乏對萬物賴以生存的自然界生態統一的關心，對此，我們的後代是不可能原諒的。

基因技術能否使人更聰明?Get Smart

Many people dream of having a smarter brain. Princeton neurobiologist Joseph Z. Tsien found the key. In September he announced that he’d built a better mouse by altering a gene that affects learning and memory. A similar process of gene manipulation might conceivably be used one day to boost intelligence in humans.

The secret lies in a feature of brain cells called the nmda receptor, which Tsien likens[1] to a cylindrical tube or window that mediates[2] the flow of information. When the window is open, chemicals called neurotransmitters flow through easily and memory is registered and stored. But as organisms mature, the window begins to close. (This may explain why children lose their facility for learning new languages when they reach sexual maturity and why some people suffer memory loss as they age.)

Tsien noticed that the receptor worked more efficiently when teamed[3] with the gene NR2B, so he introced extra NR2B genes into a batch of fertilized mouse eggs. In a normal mouse, the memory window is open for just 150-thousandths of a second. In Tsien’s specially engineered mice, the window opens for 250-thousandths of a second, long enough to make a remarkable difference in memory retention. When he pitted[4] his mice against common mice, they won paws down. Ordinary mice could recognize a Lego block for 12 hours, but smart mice could remember the block for up to three days. "That’s a profound enhancement," Tsien says.

Can it be done with humans? Maybe, but genetic engineering will have to make some extraordinary advances first. And some thorny ethical issues will have to be resolved. Meanwhile, Tsien promises to keep his furry little geniuses locked up in a lab, far from your larder. "Otherwise," he says, "you might need a smart cat or a smart mousetrap to catch them."

許多人都希望自己能變成更聰明。普林斯頓神經生物學家Joseph Z. Tsien就找到了這把開啟智慧之門的鑰匙：他於九月宣布，通過改變影響學習和記憶能力的基因培養出了一隻聰明的老鼠。類似的基因處理技術有望在未來日子裡運用到人腦，以推動人類智慧的飛躍。

該技術的奧秘就在於名為nmda感受器的腦細胞的功能。Tsien將其比作一個傳遞信息流的圓柱通道或窗口。當窗口開放時，某種稱為神經傳遞素的化學物質就能輕易流過，記憶因此登記並存儲了下來。然而，當器官成熟時，這扇窗口就開始關閉。(這也能解釋為何 兒童 長大後(性器官成熟之時)會失去掌握新語言的能力，以及為何某些人年老時會患失憶)。

Tsien注意到，當感受器與名為NR2B的基因協作時效率會更高。因此，他將NR2B基因植入一批老鼠的受精卵中。一隻普通老鼠的記憶之窗僅開放千分之150秒。而經Tsien植入基因的老鼠，記憶之窗能開放千分之250秒，這已經能夠使其 記憶力 發生驚人的改變。當他讓自己的老鼠與普通老鼠互斗時，它們竟能輕而易舉地取勝。普通老鼠能夠保留關於Lego block的記憶12小時，而聰明的老鼠居然能將記憶保持三天。“這可是一個意義深遠的進步。”Tsien這樣說。

那麼，人類也能接受這種基因移植嗎? 或許可以，但前提是基因工程得首先做出非凡的成就，還必須解決一系列棘手的倫理問題。Tsien保證他一定會將那些披著毛皮的小天才鎖入實驗室，遠離人們的食品櫃。“否則，”他說，“為了捉住他們，人們就不得不去尋找更聰明的貓或者功能更強的捕鼠器了。”

食用轉基因食品安全嗎?Food Safe To Eat?

Traditional plant breeding involve s crossing varieties of the same species in ways they could cross naturally.For example，disease-resistant varieties of wheat have been crossed with high-yield wheat to combine these properties.This type of natural gene exchange is safe and fairly predictable.

Genetic engineering(GE)involves exchanging genes between unrelated species that cannot naturally exchange genes with each other.GE can involve the exchange of genes between vastly different species――e.g.putting scorpion toxin genes into maize or fish antifreeze genes into tomatoes.It is possible that a scorpion toxin gene，even when it is in maize DNA，will still get the organism to proce scorpion toxin――but what other effects may it have in this alien environment?We are already seeing this problem――adding human growth hormone genes to pigs certainly makes them grow――but it also gives them arthritis and makes them cross-eyed，which was entirely unpredictable.

It will be obvious，for example，that the gene for human intelligence will not have the same effect if inserted into cabbage DNA as it had in human DNA――but what side-effect would it have?In other words，is GM food safe to eat?The answer is that nobody knows because long-term tests have not been carried out.

Companies wanting a GM proct approved in the UK or USA are required to provide regulatory bodies with results of their own safety tests.Monsanto’s soya beans were apparently fed to fish for10weeks before being approved.There was no requirement for independent testing，for long-term testing，for testing on humans or testing for specific dangers to children or allergic people.

The current position of the UK Government is that“ There is no evidence of long-term dangers from GM foods.”In the US，the American Food and Drug Administration is currently being prosecuted for covering up research that suggested possible risks from GM foods.

傳統的植物培育 方法 ，是依照植物自然雜交的方式，進行相同物種的人工雜交。比如，抗病小麥同高產小麥雜交，形成了一種具有雙重特性的新的小麥品種。這種自然的基因交換既安全，又具有相當的可預見性。

基因工程是在彼此毫無關系的物種之間，相互交換在自然條件下無法交換的基因。它可在有巨大差異的物種之間進行基因交換。比如，將蠍子毒素基因注入玉米，或者將魚防凍基因注入西紅柿。即使在玉米DNA中，蠍子毒素基因依然可能獲得有機組織產生蠍子毒素。但是在這種異質的環境中，這種基因產品會有什麼其他作用嗎?我們實際上已經發現這個問題：將人類生長荷爾蒙基因植入豬的體內，一定會使豬的生長加速，但是同時也使豬患上了關節炎和內斜視，而這一切是完全無法預測的。

打個比方，人類的智力基因顯而易見在人體DNA內和注入捲心菜DNA後的作用是不同的。但將它植入捲心菜中會產生什麼樣的副作用呢?換句話說，食用轉基因食品安全嗎?沒有人知道答案，因為人們尚未進行長期的測試。

在英國或者美國，一個公司如果希望其轉基因產品獲得批准，它必須向管理機構提供本公司轉基因產品安全測試的結果。Monsanto的大豆在獲得批准之前，曾用了10周時間進行喂魚試驗。目前，尚無要求對轉基因產品進行獨立測試、長期測試、人體測試，或者就其對兒童及過敏者所造成的特定危險進行測試。

英國政府目前的態度是：“尚無證據表明食用轉基因食品存在長期性的危險。”在美國，人們正在起訴美國食品葯品管理局掩蓋轉基因食品安全性的研究結果，這些研究結果表明，食用轉基因食品可能導致危險。
