期末加油呀UNIT 3Unit testA C A C BB B D A CC BD D DIn the town where I grew up, there were two creeks running through it. In the 1) winter, I'd trap muskrats, and we also skated a lot. Rocky Fork Creek ran a great distance, and we'd 2) literally skate for miles. Big Walnut Creek on the other hand was where more folks from the 3) munity came to skate socially. It was a much 4) wider creek. We'd have bonfires there and had some great hockey games, too.My friend, Zeke, had 6 5) siblings and every kid in the family had their own horse, so we'd go to Zeke's and ride through the 6) woods and meadows. Zeke would pull us onsleds using his dad's tractor. In the summer, we'd 7) explore the creeks, and I'd be 8) catching snakes and frogs, and fishing.In the summer my family and I traveled to Butler, PA to visit my grandparents. We would play golf or at night we all played cards. Grandpa would take me fishing and he and I 9) would run errands all around town in his red old car. On Friday nights he and I watched the Gillette Fights.My family and I also spent two weeks each summer at Conneaut Lake Park. There was a huge three-story hotel whose grounds were really beautiful. The park also had a small 10) golf course, and a midway, and I recall we could ride all the rides in the amusement park for only $2 on Wednesdays. I'd get up and go fishing in a nearby canal before the rest of the family awoke.UNIT 4ConversationsD B C A DB C D BPassagesB C A DScientific research should improve our overall quality of life. The government should provide financial and political support to any research that is likely to result in immediate and significant benefits for the people. However, people's ideas 1)vary when it es to whether the government should support scientific research with no practical use. Still 2) a large portion of people believe that the government should distribute adequate funds to any scientific research that aims to improve the3)well-being of people, even if it is of no practical use in the short run.Scientific research whose social benefits are immediate, predictable, and 4)profound should continue to be a high priority. For example, biotechnology research has been proven to help cure and prevent diseases; information technology enables education to be more 5) accessible; and munication technology facilitates global peace by improving mutual understanding among people and their participation in the democratic process.However, this is not to say that research whose benefits are less immediate or clear should be given a lower priority. It is difficult to predict which research will 6)ultimately lead to the greatest contributions to society. Reluctance to finance less practical scientific research could 7)have a harmful effect on the efforts to explore new knowledge. This is particularly true of the puter sciences. For instance, before the first puter was invented, public opinions 8)went against it, as most people saw nothing practical in puter research. However, puters transformed the way human society evolved and proved to be of great avail in the long run, especially in terms of scientific development in fields such as the military, medicine, 9)aviation, and education.Therefore, never should we think that scientific research whose benefits are unknown 10)is not worth pursuing since the purpose of any research should be to discover truths, whatever it might be.Unit testB C A C DC CD A DD A B A AThis might be an important scientific breakthrough. A scientist set out to improve the productivity (生产力) of farm animals and along the way set off a 1) biological earthquake. The experiment he 2) firmly pursued (从事) involved work with a cell froman adult mammal. His 3) efforts were to make a cell behave like a cell from a developing embryo (胚胎). And it was successful. He and his coworkers cloned a sheep called Dolly and introduced her to a skeptical world in February 1997.Perhaps it was his 4) isolation in a quiet rural part of Scotland that permitted him to resist the 5) objectors. Or perhaps it was the isolation of the remote field of farm animals that gave him the 6) originality. However, he seemed as surprised as anyone else that his 7) modest and simple experiment should have a great impact on our sense of what it is to be human. He wanted to use his cloning technology to 8) improve the health, the quality, and the productivity of farm animals. Any experiment with humans, he believed, should always be kept strictly at the very low level of cells and proteins. It would be 9) morally unacceptable, he said, to use his technique to create a human clone. Of course, this achievement would bring fear, debate and new 10) legislation in countries around the world. In a word, Dolly the sheep has changed the world.UNIT 5ListeningUse the skills 2.31.And I've always (1)loved fashion, so the idea that I could go to fashion shows in Paris, New York, etc. was justamazing for me. What I didn't realize is that actually being a model is really, really(3)hard work.2. A nd the problem is that you need tolook good all the time. But often,you're (2feeling terrible). 3. I could spend my days sitting in some of the best restaurants,eating delicious food, and(2)get paid for it. The only problem,which I didn't realize at the time, is that actually you canget bored of eating restaurant food.4. I used to spend hours in the gym, doing exercise to try and(1)work off the food I was eating. Butit was impossible. So, in the end, (2)I gave it up.5. I had this (1) (wonderfully romantic) idea of owning my own vineyard, making wine,and spending my life in the beautiful Tuscan countryside. But the reality is verydifferent. I had no idea (2) (how tiring) the job would be.6. A nd in September, a bad storm can (1) (ruin the grapes) in just a few minutes. Atleast when I worked in an office, I didn't use to(2)worry about the weather. Havingsaid that, I love my life. And the science of making wine isworry about the weather.More practice in listeningConversationsB B A D CB A B DPassagesD A B DA poorly trained manager can make an employee's life miserable. In 99 out of 100 cases, employees may 1) suffer from low spirits and then gradually bee no longer 2) enthusiastic about their jobs just because they have a boss who doesn't approve of them, doesn't listen to them, or generally 3) erodes their self-esteem.Three basic skills that every manager should use in order to be 4) petent on the job are: being specific, enhancing others' self-esteem and listening effectively. Being specific means giving 5) clear-cut instructions about what is to be done and the results to be achieved. Being specific also means describing the behavior of people rather than 6) labeling people. It includes giving both positive feedback that tells them what to repeat and corrective feedback that is firm, yet not critical. Then it 7) es down to evoking in the employees self-esteem. Self-esteem is a private, individual matter. It is not fixed, but goes up and down from day to day, or even from hour to hour. Thus, building self-esteem is no easy task. Managers can't MAKE people feel good about themselves, but rather, they need to help people develop their own self-esteem as self-esteem is like a door that's locked from the inside. A final skill that today's managers need more than ever is listening. Listening may seem like a 8) monplace skill, but it's not practiced as much as it should be in business today. People 9) tend to think about what they are going to say in response when another person is talking, instead of 10) focusing on what that person is saying and what he / she means.Unit testA C AB BD C A B BA C A A DDo you happen to know something about the police? In police work, you can never 1) predict the next crime or problem. No working day is 2) identical to any other. So there is no "3) typical" day for a police officer. Some days are relatively slow, and the job is 4) boring; other days are so busy that there is no time to eat. I think I can describe police work in one word: 5) variety. Sometimes it's 6) dangerous. One day, for example, I was working on a special assignment; that is, I was on the job, but I was wearing 7) normal clothes, not my police uniform. I was trying to catch 8) some robbers who were stealing from people as they walked down the street. Suddenly, seven bad men jumped out at me; one of them had a knife, and we got into a fight. Another policeman arrived, and the two of us 9) captured three of the men; but the other four ran away. Another day, I helped a woman who was going to have a baby. She was trying to get to the hospital, but there was a bad traffic jam. I put her in my police car to get her there faster. I thought she was going to have the baby 10) right there in my car. But fortunately, the baby waited to "arrive" until we got to the hospital.UNIT 6ConversationsC A B A BA C C BPassagesA DB BThe Sultana was a Mississippi River steamboat destroyed in an explosion on April 27, 1865. An 1) estimated 1,800 of the 2,400 passengers were killed, and the Sultana sank not far from Memphis, Tennessee. This disaster received little public attention, as it took place soon after the President Abraham Lincoln was 2) assassinated.The wooden steamboat was constructed in 1863 and 3) was intended to be used for the lower Mississippi cotton trade. Registering 1,719 tons, the steamboat was built to carry no more than 365 people. For two years, it ran a regular route between St. Louis and New Orleans. Sometimes it was asked to carry troops.The Sultana left New Orleans on April 21, 1865. Most of the passengers were Union soldiers who had recently been 4) released from Confederate prison camps. The US government had 5) made a contract with the Sultana to transport these former prisoners of war back to their homes in the north.At 2 a.m. on April 27, about seven miles north of Memphis, at least one boiler 6) gave way, causing a huge explosion that destroyed the center portion of the boat, throwing sleeping men high into the air before landing in the river. Confusion and chaos 7) ensued as men tried to save themselves and others. Many drowned while others burned to death.The direct cause of the explosion was later determined to be the leaky and poorly repaired steam boiler. Passengers who 8) survived the initial explosion had to risk their lives in the icy water of the Mississippi or burn with the ship. Many died of drowning or coldness. Bodies of 9) victims continued to be found downriver for months. Many were never recovered. Some of the Sultana's crew, including the captain, were among those who 10) perished.Unit testC B A C DC CD A BC AD C DIn the middle of the eighteenth century, France and Britain clashed in a conflict that has e to be known as the French and Indian War. French and Indian soldiers, sensing their mutually 1) beneficial situation in the American frontier, pulled together. And they 2) fought against British forces. But the powerful British Empire briefly 3) strengthened its hand in North America with victory in this struggle. The French slowly 4) pulled out of North America. The British, for their 5) part, determined to hand over a great piece of land. They decided that the territory west of the Allegheny Mountains and north of the Ohio River should 6) serve as a large Indian settlement closed to general settlement by English colonists.By 1783 the American Revolution had produced an 7) amazing change of fortune in North America. The United States of America 8) stood as a new nation while British soldiers retreated to the northwest (today's Michigan and Ohio).Americans eyed these lands, which the British had 9) sought to give away to the Indians in the area. As Americans moved westward into the new frontier, they replaced the French and Indian "middle ground" social agreements with a system of law emphasizing private property, farming, and eventually industrial development. Cultural ideals thatpromoted Christian 10) civilization, marked Indians as animals, and created a firm distinction in sex roles in this new system.UNIT 7ConversationsC A BD BD A B DPassagesB A A CResearch shows a close relation between reading speed and understanding that in most cases an increase in rate 1) was acpanied by an increase in prehension and a decrease in rate brought decreased prehension with it. However, simply speeding the rate especially through forced 2) acceleration may actually result in making the real reading problem more 3) severe. The obvious solution, then, is to increase rate as a part of a total 4) endeavor / endeavour of the whole reading process. Then how?You can prepare for maximum increase in rate by establishing 5) practicable habits, such as avoiding rereading and whispering while reading, learning to adjust reading rate to increase prehension.Rate adjustment may be overall adjustment, or internal adjustment within an article. As an 6) analogy, imagine that you plan to take a 100-mile mountain trip in three hours, averaging about 35 miles an hour. This is your overall rate adjustment. However, in actual driving you may slow down to 15 miles per hour on some curves, while 7) speeding up to 50 miles per hour on relatively straight sections. This is your internal rate adjustment.Poor results are inevitable if the reader 8) attempts use the same rate for all types of material and for all reading purposes. A good reader adjusts his / her reading rate from article to article, or even within a given article. So you need to 9) foster a good reading habit by daily training until a flexible reading rate bees 10) second nature to you.Unit testB A AC AD D C A BC C B A AThe first step in stopping drug use is learning why people start using drugs. The reasons people use drugs are as 1) different as people are from one another. But there seems to be one mon 2) thread: people seem to take drugs to change the way they feel. They want to feel better or feel happy or to feel 3) nothing. Sometimes, they want to forget or to remember. People often feel better about themselves when they are under the influence of drugs. But the 4) effects don't last long. Drugs don't 5) solve problems. They just hide them. No matter how far drugs may take you, it's always a 6) round trip. After a while, people who miss drugs may feel 7) worse about themselves, and then they may use more drugs. If someone you know is using drugs, you can help. You can let your friends know that you care. You can listen and 8) try to solve the problem behind your friend's need to use drugs. Two people together can often solve a problem that seems too big for one person alone. Therefore, the most important 9) part that you can play is to be there. Studies of heavy users in the United States show that they felt unloved and unwanted. They didn't have close friends to talk to. When you or yourfriends 10) take the time to care for each other, you're all helping to stop drugs abuse.After all, what is a friend for?UNIT 8ConversationsA C D A AD B C DPassagesA C C DThe most useful bit of the media is disappearing. In North America, newspapers are now an 1) endangered species. The business of selling words to readers and selling readers to advertisers, which has sustained their role in society, is 2) falling apart.Of all the old media, newspapers have the most to lose from the Internet. Circulation has been falling in many countries. But in the past few years the Web has hastened the decline. In his book The Vanishing Newspaper, Philip Meyer 3) calculates that the first quarter of 2043 will be the moment when newsprint dies in America as the last exhausted reader 4) tosses aside the last crumpled (弄皱的) edition.Advertising is following readers who 5) turn to the Internet. The rush is intense, largely because the Internet is an attractive medium that 6) unprecedentedly matches buyers with sellers and proves to advertisers that their money is well spent. In Switzerland and the Netherlands newspapers have lost half their 7) classified advertising to the Internet.Newspapers have not yet started to 8) shut down in large numbers, but it is only a matter of time. Over the next few decades half of North America's general papers may fold.Jobs are already disappearing. According to the Newspaper Association of America, the number of people employed in the newspaper industry fell by 9) approximately 18 percent between 1990 and 2004. Moreover, this year Morgan Stanley, an investment bank, attacked the New York Times pany, because its share price had fallen by nearly 50 percent in four years. This may suggest, to some extent, that tumbling shares of listed newspaper firms have prompted 10) fury from investors.Unit testA AB D CB DC C AB C A D CFor many of us, municating used to mean sending letters and cards through the mail and getting no response until weeks later. We'd pass 1) hand-written notes to friends in class. We'd pick up the telephone — paying for 2) long-distance calls — and could only talk to one person at a time. On top of that, there were no 3) answering machines to leave messages if a person wasn't home, or Caller ID to 4) screen calls if we didn't feel like picking up the phone. And pay phones were the only 5) option to call home ifour car broke down on the side of the road, or if we had to stay after school. For the past decade or so, technology has 6) transformed the way we municate, in part due to the use of the Internet. Instead of 7) mailing letters, we're writing s through Gmail or Windows Live Hotmail that can be sent 8) instantly to the recipient (接受者). We can even add multiple recipients to these s, so that more than one person can read them. Even more, we can send greeting cards over the Web. And no postage is needed! Sending a note to a friend can be done 9) in a matter of seconds. We are no longer bound to long-distance charges, either. Mobile phones have bee a 10) god-send gift, letting us place calls no matter where we are. And text messaging has bee an efficient way to get a short message across, such as "Meet you there at 8" or "I'll be home late."。

In fact,right now we have too much data sitting in computers.For example,we have thousands of photos of planet mars taken by telescopes that nobody has ever seen.We have them yet.Nobody has had time to look at them with their own eyes,let alone analyze them.Questions one to four are based on the conversation you have just heard.Question1.Why does the woman say she can be so energetic?答案：Oh,well,I just love what I do.Question2.What has the woman been engaged in?答案：The education of science and the further understanding of science.Question3.What does the woman say about the benefit teaching brings to her?答案：teaching a subject helps me comprehend it better myselfQuestion4.How does the woman say new scientific breakthroughs can be made possible?答案：to look at them with their own eyes and analyze themConversation two.对于梦的起源的探讨(摊手)M：Do you think dreams have special meanings?W：No,I don't think they do.M：Don't either.But some people do.I would say people who believe that dreams have meanings are superstitious,especially nowadays,in the past,during the times of ancient Egypt,Greece or China,people used to believe that dreams could foresee the future.But today,with all the scientific knowledge that we have,I think it's much harder to believe in these sorts of things.W：My grandmother is superstitious,and she thinks dreams can predict the future.Once she dreamed that the flight she was due to take the following day crashed,can you guess what she did?She didn't take that flight.She didn't even bother to go to the airport the following day.Instead she took the same flight.But a week later,everything was fine.Of course,no plane ever crashed.M：How funny did you know that flying is actually safer than any other mode of transport?It's been statistically proven.People can be so irrational sometimes.W：Yes,absolutely.But even if we think they are ridiculous,emotions can be just as powerful as rational thinking.M：Exactly.People do all sorts of crazy things because of their irrational feelings.But in fact, some psychologists believe that our dreams are the result of our emotions and memories from that day.I think it was Sigmund Freud who said that children's dreams were usually simple representations of their wishes,things they wished would happen.But in adults,dreams a much more complicated reflections of their more sophisticated sentiments.W：Isn't it interesting how psychologists try to understand using the scientific method something as bizarre as dreams?Psychology is like the rational study of irrational feelings.Questions five to eight are based on the conversation you have just heard.Question5.What do both speakers think of dreams?答案：they don’t have special meaningsQuestion6.Why didn't the woman's grandmother take her scheduled flight?答案：Once she dreamed that the flight she was due to take the following day crashedQuestion7.What does the woman say about people's emotions?答案：emotions can be just as powerful as rational thinking.Question8.What did psychologist Sigmund Freud say about adults dreams?答案：But in adults,dreams a much more complicated reflections of their more sophisticated sentiments.Passage one.南极考察队对于V湖冰面下生物的探索While some scientists explore the surface of antarctica,others are learning more about a giant body of water four kilometres beneath the ice pack.Scientists first discovered lake Voss dock in the19seventy's by using radio waves that penetrate the ice.Since then,they have used sound waves and even satellites to map this massive body of water.How does the water in lake Vohs dog remain liquid beneath an ice sheet?The thick glacier above acts like an insulating blanket and keeps the water from freezing,says Martin Siegert, a glaciologist from the university of Wales.In addition,geothermal heat from deep within the earth may warm the hidden lake.The scientists suspect that microorganisms may be living in lake vohs stock closed off from the outside world for more than2million years.Anything found there will be totally alien to what's on the surface of the earth to see a good scientists are trying to find a way to drill into the ice and draw water samples without causing contamination.Again,robots might be the solution.If all goes as planned,a drill shaped robot will through the surface eyes.When it reaches the lake,it will release another robot that canswim in the lake,take pictures,and look for signs of life.The scientists hope their discoveries will shed light on life in outer space,which might exist in similar dark and airless conditions.Recently,close up pictures of jupiter,as moon europa shows signs of water beneath its icy surface. Once tested in antarctica,robots could be sent to europa to search for life there too.Questions9to11.Based on the passage you have just heard.Question9.What did scientists first use to discover lake V stock in the1970s?答案：using radio waves that penetrate the iceQuestion10.What do scientists think about lake vast dock?答案：microorganisms may be living in lake vohs stock closed off from the outside world for more than2million yearsQuestion11.What do the scientists hope their discoveries will do?答案：shed light on life in outer space,which might exist in similar dark and airless conditionsPassage two.吉姆斯对于印第安语言的记录及其科研过程和心得The idea to study the American Indian tribe torah,who Morris came to James Copeland in1984, when he discovered that very little research had been done on their language.He could did a tribe member through a social worker who worked with the tribesmen in Mexico.At first,the tribe member named gonzales was very reluctant to cooperate.He told Copeland that no amount of money could buy his language.But after Copeland explained to him what he intended to do with his research and how it would benefit that are home,orris gonzales agreed to help.He took Copeland to his village and served as an intermediary.Copeland says,thanks to him that are who Morris understood what our mission was and started trusting us.Entering the world of that,Hamas has been a laborious project for Copeland.To reach their homeland, he must drive2.5days from Houston,Texas.He loads up his vehicle with goods that the tribesmen can't easily get and gives the goods to them as a gesture of friendship that are Morris,who don't believe in accumulating wealth,take the food and share it among themselves.For Copeland,the experience has not only been academically satisfying,but also has enriched his life in several ways.I see people rejecting technology and living a very hard,traditional life,which offers me another notion about the meaning of progress in the western tradition.Hesays,I experience the simplicity of living in nature that I would otherwise only be able to read about.I see a lot of beauty in their sense of sharing and concern for each other.Questions12to15are based on the passage you have just heard.Question12.Why did James Copeland want to study the American Indian tribe torah Morris?答案：he discovered that very little research had been done on their languageQuestion13.How did gonzalez help James Copeland?答案：He took Copeland to his village and served as an intermediaryQuestion14.What does the speaker say about James copeland's trip to that are humorous village?答案：don't believe in accumulating wealth,take the food and share it among themselvesQuestion15.What impresses James Copeland about that are a humorist tribe,答案：I see a lot of beauty in their sense of sharing and concern for each other.recording one.到底什么是激进?女权主义是激进嘛?What is a radical?It seems today that people are terrified of the term,particularly of having the label attached to them.Accusing individuals or groups of being radical often serves to silence them into submission,thereby maintaining the existing state of affairs,and more important, preserving the power of a select minority who are mostly wealthy white males in western society.Feminism is a perfect example of this phenomenon.The women's movement has been plagued by stereotypes,misrepresentations by the media,and accusations of man hating and radicalism.When the basic foundation of feminism is simply that women deserve equal rights in all facets of life, when faced with a threat of being labeled radical women back down from their worthy cause and consequently participate in their own oppression,it has gotten to the point that many women are afraid to call themselves feminists because of the stigma attached to the word.If people refuse to be controlled and intimidated by stigma,as the stigma as lose all their power,without fear and which to feed such stigma as can only die.To me,a radical is simply someone who rebels against the norm.What advocates a change in the existing state of affairs?On closer inspection,it becomes clear that the norm is constantly involving and therefore is not a constant entity.So why there is deviation from the present situation?Such a threat than the state of affairs itself is unstable.And subject to relentless transformation,it all goes back to maintaining the power of those who have it and preventing the rise of those who don't.In fact,when we look at the word radical in a historical context,nearly every figure we now hold up as a hero was considered a radical in his or her time.Radicals are people who affect change.They are the people about whom history is written.Abolitionists were radicals.Civil rights activists were radicals, even the founders of our country in their fight to win independence from England or radicals. Their presence in history has changed the way our society functions,mainly by shifting the balance of power that previously existed.There are some radicals who have made a negative impact on humanity.But undeniably,there would simply be no progress without radicals.That being said, next time someone calls me a radical,I will accept that label with pride.Questions16to18are based on the recording you have just heard.Question16.What usually happens when people are accused of being radical?答案：preserving the power of a select minority who are mostly wealthy white males in western society.Question17.What is the speaker's definition of a radical?答案：a radical is simply someone who rebels against the norm.Question18.What does the speaker think of most radicals in the American history?答案：there would simply be no progress without radicals.Recording two.人的社会性因素：不可避免的被环境影响We are very susceptible to the influence of the people around us.For instance,you may have known somebody who has gone overseas for a year or so and has returned with an accent.Perhaps.We become part of our immediate environment.None of us are immune to the influences of our own world.And let us not kid ourselves that we are untouched by the things and the people in our life.Fred goes off to his new job at a factory.Fred takes his10minute coffee break,but the other workers take a half an hour.Fred says,what's the matter with you guys?Two weeks later,Fred is taking20minute breaks.A month later,Fred takes his half hour.Fred is saying,if you can't beat them,join them,why should I work any harder than the next guy?The fascinating thing about being human is that generally we are unaware that there are changes taking place in our mentality.It is like returning to the city smog after some weeks in the fresh air.Only then do we realize that we have become accustomed to the nasty smells mix with critical people.And we learn to criticize mixed with happy people.And we learn about happiness.What this means is that we need to decide what we want from life and then choose our company accordingly.You may well say that is going to take some effort.It may not be comfortable.I may offend some of my present company.Right?But it is your life.Fred may say I'm always broke frequently depressed. I'm going nowhere and I never do anything exciting.Then we discover that friends,best friends, are always broke,frequently depressed,going nowhere and wishing that life was more exciting. This is not coincidence.Nor is it our business to stand in judgment of Fred.However,if Fred ever wants to improve his quality of life,the first thing he'll need to do is recognize what has been going on all these years.It's no surprise that doctors as a profession suffer a lot of ill health because they spend their lives around sick people.Psychiatrists have a higher incidence of suicide in their profession for related reasons.Traditionally,nine out of tension,whose parents'smoke smoke themselves.Obesity is in part an environmental problem.Successful people have successful friends.And so the story goes on.Questions19to21are based on the recording you have just heard.Question19.What does the speaker say about us as human beings?答案：None of us are immune to the influences of our own world.Question20.What does the speaker say Fred should do first to improve his quality of life?答案：It is like returning to the city smog after some weeks in the fresh airQuestion21.What does the speaker say about psychiatrists?答案：Psychiatrists have a higher incidence of suicide in their profession for related reasons.Recording three.美元的发展历史(这玩意有啥可说的?)Virtually every American can recognize a dollar bill at a mere glance.Many can identify it by its sound or texture.But few people indeed can accurately describe the world's most powerful, important currency.The American dollar bill is colored with black ink on one side and green on the other.The exact composition of the paper and ink is a closely guarded government secret. Despite its weighty importance,the dollar bill actually weighs little.It requires nearly500bills to tip the scales at a pound.Not only is the dollar bill lightweight,but it also has a brief lifespan.Few dollar bills survive longer.18months.The word dollar is taken from the German word,tailor the name for the world's most important currency in the16th century.The Thaler was a silver coin first minted in1518under the reign of Charles the5th,emperor of Germany.The concept of paper money is a relatively recent innovation in the history of American currency. When the constitution was signed,people had little regard for paper money because of its steadily decreasing value during the colonial era.Because of this lack of faith,the new American government minted only coins for common currency.Interest bearing bank notes were issued at the same time. But their purpose was limited to providing money for urgent government crises,such as American involvement in the war of1812.The first non interest bearing paper currency was authorized by congress in1862.At the height of the civil war.At this point,citizens,old fears of devalued paper currency had calmed.The dollar bill was born.The new green colored paper money quickly earned the nickname greenback.Today,the American dollar bill is a product of the federal reserve and is issued from the12federal reserve banks around the United States.The government keeps a steady supply of approximately2billion bills in circulation at all times.Controversy continues to surround the true value of the dollar bill.American history has seen generations of politicians argue in favor of a gold standard for American currency.However,for the present,the American dollar bill holds the value that is printed on it and little more.The only other guarantee on the bill is a federal reserve pledge as a confirmation in the form of government securities.Questions22to25are based on the recording you have just heard.Question22.What does the speaker say about the American dollar bill?答案：The American dollar bill is colored with black ink on one side and green on the otherQuestion23.What does the speaker say about the exact composition of the American dollar bill?答案：a closely guarded government secret.Question24.Why did the new American government mint only coins for common currency?答案：because of its steadily decreasing value during the colonial era.Because of this lack of faithQuestion25.What have generations of American politicians argued for?答案：in favor of a gold standard for American currency。

Here are four landmarks in Antarctica and the female pioneers they’re named after.Jones TerraceThe ice-free terrace in eastern Antarctica’s Victoria Land bears Jones’ name. In 1969, geochemist Lois M. Jones led the first all-female research team from the U. S. to work in Antarctica. Jones and her team studied chemical weathering in the McMurdo Dry Valleys, an ice-free area of Antarctica. Through chemical analyses of rocks they had collected, Jones and her team discovered many geochemical characteristics of the valley’s ice-covered lakes.Mount Fiennes8,202-foot-high Mount Fiennes, located on Antarctica’s largest island — Alexander Island — is named after Ginny Fiennes. She established and maintained 80-foot-tall radio towers in the Antarctic with her colleagues. In 1985, Fiennes became the first female invited to join the Antarctic Club, a British supper club open to individuals who have spent extended time in the Antarctic region.Francis PeakThe 3,727-foot-tall peak on Antarctica’s Adelaide Island is named after Dame Jane Francis, who is the first female director of the British Antarctic Survey, the national polar research institute of the UK. Her collection of fossils on Seymour Island helped conclude in a 2021 paper that Antarctica’s abundant plant fossils indicate the continent once had a much warmer climate than it currently does.Peden CliffsPeden Cliffs near Antarctica’s Marie Byrd Land are proof of the labor of Irene Peden. She was the first American female scientist to both live and work in the Antarctic, where she used radio waves to study ice sheets. Peden and her team determined how very low frequency radio wave spread over long polar distances by measuring pathways in the ice. They also used varying radio wave frequencies to measure the thickness of Antarctica’s ice sheets.16．What do the first two pioneers have in common?A．They analyzed different chemicals of rocks in Antarctica.B．They both worked with their own team in Antarctica.C．They conducted the research in the ice-free areas in Antarctica.D．They joined the Antarctic Club for their stay in Antarctica.17．Who proved the previous higher temperatures of the Antarctic?A．Lois M. Jones.B．Ginny Fiennes.C．Dame Jane Francis.D．Irene Peden.18．What is the scientific breakthrough of Irene Peden?A．She was the first American scientist to explore the Antarctic.B．She measured the spreading frequencies of radio waves.C．She found out the thickness of Antarctica’s ice sheets.D．She discovered a lot of ice-covered lakes in the Antarctic.Canadian author Alice Munro, a master of the contemporary short story, passed away on May 13, 2024, at 92.Munro’s texts featured depictions of everyday but decisive events, pulling vast themes out of ordinary settings. Her characters often mirrored her own rural Ontario lifestyle. In an interview after winning the Nobel Prize, she said that living in a small town gave her the freedom to write. “I don’t think I could have been so brave if I had been living in a city, competing with people on what can be called a generally higher cultural level,” she said. “As far as I knew, at least for a while, I was the only person I knew who wrote stories.”Munro’s first short story was published when she was 37, a college dropout squeezing in writing time around her children’s naps. By the time she was in her 60s, she had become one of the most celebrated short-story writers in the world. Throughout her long career, she hardly ever failed to wow readers and critics with her quietly powerful language. In reviewing her last collection, Dear Life, NPR critic Alan Cheuse wrote “A Munro story gives us so much life within the bounds of a single tale that it nourishes (滋养) us almost as much as a novel does.”In a literary culture that tends to celebrate novels over shorter fiction, Munro has been a constant advocate for the power of the short story. In the interview, Munro emphasized the significance of her win not for herself, but for her art form: “I really hope this would make people see the short story as an important art, not just something you play around with until you get a novel written.”When asked “Do you want young women to be inspired by your books and feel inspired to write?” Munro replied, “I don’t care about that. I want people to find not so much inspiration as great joy. I want them to think of my books as related to their own lives in ways.”19．Why did Munro feel free to write while living in rural areas?A．She was inspired by rural landscape and lifestyles.B．She was free from stress of a more cultured setting.C．She had more courage to compete with urban writers.D．She had access to ordinary people and decisive events.20．What did Alan Cheuse say about Munro’s stories in Dear Life?A．They promote readers’ mental well-being.B．They have broken the length limit of short stories.C．They impress readers with quietly powerful language.D．They offer richness and depth in shorter format.21．How did Munro view the short story in literary culture?A．It is more powerful than novels.B．It is a way of entertainment for young writers.C．It is as important an art form as novels.D．It is an inspiration for young writers. 22．What did Munro want readers to get by reading her books?A．Inspiration to become writers themselves.B．Enjoyment and connection to their own lives.C．Pleasure and motivation to change their lives.D．Information about art forms and literary culture.Handwriting notes in class might seem old-fashioned as digital technology affects nearly every aspect of learning. But a recent study in Frontiers in Psychology suggests that taking notes with pen and paper is still the best way to learn, especially for young children.The new research builds on a 2014 study that suggested people may type notes quickly, without thinking much about what they’re writing-but writing by hand is slower and makes them actively pay attention to and process the incoming information. This conscious action of building on existing knowledge can make it easier for students to stay engaged and grasp new concepts.To understand specific brain-activity differences during the two note-taking approaches, the authors of the new study sewed 256 electrodes (电极) into a hairnet. These sensors let the scientists record 36 students’ brain activity as they wrote or typed words displayed on a screen. When students wrote by hand, the sensors picked up widespread brain connectivity throughout visual regions that receive and process sensory information, and the motor cortex (运动皮层) that helps the brain use environmental inputs to inform a person’s next action. Typing, however, resulted in minimal activity in these brain regions.Vanderbilt University educational neuroscientist Sophia Vinci-Booher says the recent studyhighlights the clear tie between physical actions and concept understanding, “As you’re writing a word, you’re taking this continuous understanding of something and using motor system to create it.” That creation then affects the visual system, where it’s processed again-strengthening the connection between an action and the words associated with it.Vinci-Booher notes that the new findings don’t mean technology is always a disadvantage in the classroom. Digital devices can be more efficient for writing essays and offer more equal access to educational resources. However, there’s a growing trend of relying on digital devices to perform cognitive (认知的) tasks, such as taking photos instead of memorizing information. Yadurshana Sivashankar, an researcher at the University of Waterloo says, “If we’re not actively using these areas, then they are going to become worse over time, whether it’s memory or motor skills.”23．Why does the author mention the 2014 study?A．To present different research findings.B．To make the new research more convincing C．To compare two note taking approaches.D．To show the advantage of writing slowly 24．What can be learned from the experiment in Paragraph 3?A．Sensors were used to process visual information.B．Electrodes were connected to students’ hair directly.C．Writing by hand activated more brain activity than typing.D．Typing stimulated the motor cortex to inform following action.25．What would Sophia Vinci-Booher probably advise students to do?A．Make better use of motor system.B．Take advantage of digital devices.C．Adopt a new approach to taking notes.D．Memorize words by writing essays. 26．What is the main idea of the text?A．Technology is not a disadvantage in classroom.B．Writing by hand comes with learning benefits.C．Taking notes enhances students’ brain activity.D．Two note-taking approaches have clear differences.The more scientists investigate the microbes (微生物) living inside us, the more they learn about the surprising impact of the tiny organisms on how we look, act, think, and feel. Are ourhealth and well-being really driven by the bacteria, viruses and fungi that live in our intestines (肠), in our lungs, on our skin, on our eyeballs? What a weird concept — that the bugs we carry around appear to be essential to establishing the basic nature of who we are.The effects of the microbiome, the microorganisms that exist in human body, can be profound and can start incredibly early. In a study, scientists showed that something supposedly as natural as a child’s character might be related to the bacteria in an infant’s digestive system; the more Bifidobacterium (双歧杆菌) there are, the sunnier the baby is. This observation, from the University of Turku in Finland, is based on an analysis of samples from 301 babies. Those with the highest proportion of Bifidobacterium organisms at two months old were more likely to exhibit a trait the researchers called “positive emotionality” at six months old.Microbiome science is still relatively young. Most studies so far have been initial and small-scale, involving only a dozen or so mice or humans. Scientists have found associations between the microbiome and disease but can’t yet draw clear cause-and-effect conclusions about our extensive collection of microorganisms and their effects on us as hosts. Still, the collection itself is mind-boggling — it’s now thought to be around 38 trillion microbes for a typical young adult male, slightly more than the number of actual human cells. And the prospects for putting that collection to use are more than promising.In the not-too-distant future, according to the most enthusiastic researchers, it might be a routine for us to take a dose of healthy microbes in various forms. Hopefully, with the help of new medical advances, we will be able to achieve our full potential by functioning at peak levels internally and externally.27．What can we learn about microbiome?A．The development of microbiome is quite mature nowadays.B．The more Bifidobacterium an adult has, the healthier one is.C．More microbes than human cells are present in young men.D．Microbes have little influence on shaping our identity28．What does the underlined word “mind-boggling” in Paragraph 3 probably mean?A．Weakening.B．Astonishing.C．Disturbing.D．Misleading. 29．What can be inferred from the text?A．It’s necessary to remove certain fungi from our body.B．2-month-old babies are often more positive than 6-month-old ones.C．New supplements related to microbiome are likely being developedD．The relationship between microorganisms and disease remains unclear.30．Which of the following can be the best title for the text?A．How microbes benefit our health.B．How microbes shape our lives.C．What affects early childhood.D．What Turku University reveals about microbes.On a large scale, making the world a better place can seem challenging. 31 As a leader, your perspectives and ideas can directly impact your community for the better. Here are some ways to make an impact and grow your leadership through emotional intelligence.32 Being able to provide a safe space through deep listening creates trust, which lays the foundation for meaningful relationships and fruitful partnerships. As a result, people are more likely to share openly and honestly. Empathy and listening will increase the quality of your relationships and skyrocket your results.Making a positive impact can also be as simple as taking the time to acknowledge and inspire someone into action. Taking time to acknowledge someone by letting them know you see their efforts and talents. 33 An example of what this could sound like is, “Wow! I am blown away by your project. What I see possible for you is to share with the rest of the team how to do it too.”Get involved with your already existing communities and networking circles. Start by connecting with your peers and ask them about causes they’re already involved in. 34 There is almost no limit to the impact you can create contributing to a cause that matters to you and your peers. With a little time, you can make a big difference.Sharing your knowledge and strengths is another essential skill. When you share with others, you’re teaching them something special about you and your journey. Imagine what would be possible if your community was in the mode of cooperation and contribution. This approach creates new ideas and opportunities. 35A．Show your kindness and respect to others.B．This informs them that they are appreciated.C．As your conversation continues, ask what is needed.D．Support your friends and colleagues by listening actively.E．When you are in contribution to others, you make a positive impact.F．As a leader, you have your own unique set of strengths and knowledge.G．One person may not change the world, but you can make a positive impact daily.三、完形填空At one night in July 2020 in Reykjavik, Halli was wandering around the city’s main street with his wife and two kids. During their walk, his three-year-old son was 36 and wanted a drink from the corner store. But Halli soon discovered he couldn’t help with the 37 request: A 20-centimetre step 38 his access to the store.The barrier was all too 39 . Born with muscular dystrophy (肌肉萎缩), which causes progressive 40 and loss of muscle, Halli, now 46, has been using a wheelchair since he was 25.As he 41 his wife and children outside the shop, he recalls, “I thought about how very strange it is that we always 42 families in this way.”Living all over the world as a creative director and digital designer, Halli had 43 first hand how different cities consider and plan for accessibility, from ramps (坡道) and sidewalks to public transportation. He decided to start with a project to make Iceland wheelchair 44 .Ramp Up Reykjavik launched as a non-profit in 2021 with a 45 to build 100 ramps within 1 year.

北师大版高三英语选择性必修第四册(2020版U12_L1_Scientific_Break参考译文
Unit12 Lesson1 Scientific Breakthroughs 参考译文第一课科学突破如果必须在20世纪重大发现中选出最重要的一项，这可不是件容易的事。
在仅仅100年中，世界就完全变样了。
医学、通信和交通方面都有惊人的发现，更别提我们对世界和太空的认识了。
医学上的进步范围很广，从利用显微镜揭示病因，施行手术，到用捐赠的器官做器官移植。
移动电话的使用给通信业带来了改变，通信方式从写信到发电子邮件和发送即时信息。
我们开始坐飞机周游世界，把人造卫星发射至轨道。
同时，科学家们发现了如何分裂原子，在此之前，原子被认为是宇宙中最小的物质微粒。
尽管不太可能选出哪项发现是最重要的，但是挑选出20世纪的几位先驱还是可能的。
例如以下几位。
20 世纪最杰出的科学家，爱因斯坦是其一。
1905年夏天，这个坦率的年轻人给他一岁的孩子晃动摇篮时，突然受到启发。
于是，“E=mc2”诞生了。
它证明了一小块物质可以产生巨大的能量。
爱因斯坦随后在他的“相对论”中指出，即使是时间、质量或长度也不是恒定不变的，它们根据我们对它们的感知而变化。
1929年，另一项重要的发现由生物学家亚历山大·弗莱明发现了。
在去度假之前，弗莱明在实验室里放了一个培养细菌的器皿。
回来时，他注意到器皿里有点儿奇怪。
经过反复检查，他发现器皿里有一种蓝色的霉菌，而霉菌周围的细菌已经被杀死了。
这种蓝色的霉菌实际上是自然状态的青霉素，弗莱明认为它可以用来杀死细菌。
数年后，青霉素开始大量生产，帮助挽救了数百万人的生命。
弗莱明对他这一惊人的发现态度谦虚，他说：“是大自然制造了青霉素，我只是发现了它。
”第二次世界大战期间，正当弗莱明的发现首次用来帮助治愈疾病时，美国海军正在寻找提高导弹精度的方法。
海军求助于工程师埃克特和物理学家莫克利，两人共同制造一台机器来完成这项工作。
尽管机器在1946年战争结束后才制造出来，但仍产生了巨大影响。
这台巨大的机器是世界上第一台计算机，但是与今天的计算机完全不同。

She's a really cool lady who did something amazing that helped save millions of lives! Let me tell you all about her.Tu Youyou was born in 1930 in China. When she was young, she loved studying plants and traditional Chinese medicine. Little did she know, this passion would lead her to make one of the most important medical discoveries of the 20th century!In the 1960s, malaria was a huge problem, especially for soldiers fighting in the jungles of Vietnam. Malaria is a deadly disease caused by parasites spread by mosquitoes. Thousands of people were篇2Tu Youyou: The Woman Who Helped Conquer MalariaHave you ever heard of Tu Youyou? She's this really cool lady from China who helped save millions of lives by discovering a cure for malaria! Malaria is a nasty disease caused by tiny parasites that infected people get from mosquito bites. It used to kill a ton of people, especially in hot places like Africa.Tu Youyou was born in 1930 in a town called Ningbo. When she was little, she loved studying plants and traditional Chinese medicine. Her parents were very poor, but they worked really hard to give Tu Youyou a good education. She was such a bright student that she got into university to study pharmaceutical chemistry.In the 1960s, malaria was a huge problem, especially for soldiers fighting in jungles during the Vietnam War. The Chinese government asked scientists to find a cure. Tu Youyou was part of the team researching traditional Chinese remedies for the disease. This was a smart idea because Chinese medicine had been around for thousands of years!For years, Tu and her colleagues read ancient texts and tested hundreds of different herb recipes on malaria parasites. They had many failures, but Tu never gave up. Finally, in 1972, she discovered that an herb called sweet wormwood could cure malaria with few side effects. This was an amazing breakthrough!It took many more years of research, testing, and convincing skeptics before the anti-malarial drug artemisnin became widely used. But eventually, it helped save millions from the deadly disease across Africa, Asia, and beyond. In 2015, at age 84, Tu Youyou's incredible perseverance and discovery were honored with the Nobel Prize in Medicine.I think Tu Youyou is such an inspiration, especially for girls who want to become scientists! She showed that even if you face many obstacles and setbacks, you should never stop pursuing your goals. Her story proves that brilliant discoveries can come from unexpected places, like ancient medical texts. Most of all, Tu's work has improved and saved countless lives around the world.The next time you learn about an important scientist or inventor, I hope you'll remember the pioneering work of Tu Youyou. She was a true problem-solver who helped conquer one of humanity's biggest threats through her intelligence, diligence, and belief in the power of natural remedies. Tu Youyou is a great example of how one person's scientific curiosity and perseverance can create amazing change!篇3Tu Youyou - The Woman Who Helped Cure MalariaYou know how teachers are always telling us to study hard and pay attention in class because education is important? Well, let me tell you about this super cool lady named Tu Youyou who is living proof of why listening to your teachers can pay off big time!Tu Youyou grew up in China back when the country was really poor. Her family didn't have much money, but her parents valued education and made sure she went to school. Tu was a good student who loved reading and learning about Traditional Chinese Medicine from old books. Little did she know that her curiosity and hard work would one day help save millions of lives!In the 1960s, malaria was a huge problem, especially for soldiers fighting in the jungles of Vietnam. Malaria is this terrible disease spread by mosquitoes that causes fevers, chills, and can even kill you if left untreated. The malaria parasites were getting resistant to the drugs used to treat the disease, so new cures were desperately needed.That's when the Chinese government put together a top secret research team called "Project 523" to try to find better malaria treatments. They recruited scientists from across China,including Tu Youyou who was working at a factory at the time. The team was tasked with combing through ancient medical texts for any clues about potent anti-malarial herbs and remedies.Now most people probably would have given up after a few weeks of reading boring, old manuscripts written with crazy ancient terminology. Not Tu Youyou though! This lady was determined. For years, she got up at 4am to study and take notes before going to work at the factory. She read through over 2,000 recipes and ancient texts, taking meticulous notes.Finally, in 1972, Tu had a breakthrough. She discovered references to something called "qinghao" or sweet wormwood, which was used centuries ago to treat fever. She began extracting and purifying the compounds from the wormwood plant. Through trial and error, she figured out the precise way to extract the most potent anti-malarial compound called artemisinin.When artemisinin was tested, the results were incredible! The new drug could clear malaria infections with minimal side effects. It was more effective than anything else on the market at the time. Project 523's work is estimated to have saved millions of lives, especially in Africa where malaria was rampant.For her persistence, intelligence, and contributions to global health, Tu Youyou was awarded the 2015 Nobel Prize in Medicine, becoming the first Chinese woman to win a Nobel. How cool is that?Tu's story shows that being a curious lifelong learner and working really hard at something you're passionate about can literally change the world. It doesn't matter if you come from a humble background or face huge obstacles. With grit and determination, you can achieve great things.The next time you're struggling with a tough homework assignment or feeling unmotivated, think about Tu Youyou waking up at 4am to pore over ancient texts to find a cure for malaria. Let her inspirational story give you a burst of motivation to pursue your education! Who knows, maybe your hard work and curiosity could lead to the next big scientific breakthrough someday.篇4Tu Youyou: The Hero Who Conquered MalariaHave you ever heard of Tu Youyou? She's a true hero in my book! Tu Youyou is a Chinese scientist who made agroundbreaking discovery that has saved millions of lives from the deadly disease of malaria.I first learned about Tu Youyou in my science class. Our teacher told us about her amazing journey and how she dedicated her life to finding a cure for malaria. It all started during the Vietnam War when many Chinese soldiers were falling ill with this terrible disease. The government knew they needed to act fast, so they assembled a team of scientists to find a cure.Tu Youyou was part of this team, and she was determined to find a solution. She didn't have fancy labs or modern equipment, but she had something even more powerful – her brilliant mind and her willingness to think outside the box.Instead of using modern methods, Tu Youyou turned to ancient Chinese medical texts for inspiration. She spent years poring over these old books, looking for any clues or remedies that could help fight malaria. It was like trying to find a needle in a haystack, but Tu Youyou never gave up.Finally, after countless hours of research and experimentation, she made a breakthrough. She discovered that a compound found in sweet wormwood, an herb used in traditional Chinese medicine, was incredibly effective at treatingmalaria. This compound, which she named artemisinin, was a game-changer in the fight against this deadly disease.But Tu Youyou's journey didn't end there. She had to go through years of clinical trials and testing to prove that her discovery was safe and effective. And even after it was proven successful, there were still many hurdles to overcome, like getting the cure distributed to the people who needed it most.Despite all these challenges, Tu Youyou never lost her determination. She was driven by a deep desire to help others and make the world a better place. And her hard work paid off in a big way.Thanks to Tu Youyou's discovery, millions of lives have been saved from malaria. In fact, it's estimated that her cure has saved over a billion people from this deadly disease. That's incredible!But Tu Youyou didn't stop there. Even after her groundbreaking discovery, she continued to work tirelessly, researching new ways to fight other diseases and improve people's lives.In 2015, Tu Youyou's incredible achievements were recognized when she was awarded the Nobel Prize in Physiology or Medicine. She was the first Chinese scientist to receive thisprestigious honor, and it was a well-deserved recognition of her life's work.To me, Tu Youyou is a true inspiration. She showed that with determination, hard work, and a willingness to think outside the box, anything is possible. She didn't let obstacles or setbacks stop her from pursuing her goal of finding a cure for malaria.Tu Youyou's story teaches us that even one person can make a huge difference in the world. Her discovery has saved countless lives, and her legacy will continue to inspire generations of scientists and researchers to come.So the next time you hear someone say that one person can't change the world, remember the story of Tu Youyou – the humble scientist who conquered malaria and became a true hero for millions of people around the globe.篇5Tu Youyou - A Scientific Hero for the AgesHi everyone! Today I want to tell you about someone who is a huge hero of mine - Tu Youyou. She's a Chinese scientist who made one of the most important medical discoveries of the 20th century. Get ready, because her story is totally amazing!Tu Youyou was born in 1930 in a poor village in Zhejiang Province. Life was really tough back then, especially for girls. But Tu was a super smart kid and loved studying. Even though she had to drop out of school after 5th grade to help support her family, she never stopped reading and learning on her own.When she was a teenager during World War 2, the Japanese army occupied her village. Tu saw so much suffering around her from malaria, a deadly disease spread by mosquitoes. Millions of people were dying from malaria every year, including many Chinese soldiers fighting the Japanese. It was a huge crisis!After the war, Tu joined a secret government project in 1969 to find a cure for malaria. For years, Western scientists had been trying to develop malaria drugs, but nothing worked very well. So Tu's team decided to look for answers in ancient Chinese medicine texts instead.Tu poured through thousands of ancient texts, looking for any mentions of remedies for fever or malaria-like symptoms. She found one very promising lead - an ancient recipe for a "sweet wormwood drink" used to treat fever. The key ingredient was wormwood, a type of plant.But there was a big problem. When Tu's team tested wormwood extracts, they didn't work at all! Tu refused to give upthough. She tried every extraction method in the book, tweaking things over and over. Nothing.Then, one day in 1972, Tu had a brilliant idea. In the ancient text, the instructions said to soak the wormwood first. So that's what she did - she soaked the wormwood in a special ether solution first before extracting it. And amazingly, it worked! The extract was incredibly effective at knocking out malaria parasites.After more testing, Tu's team had a 100% cure rate for malaria, even for patients with severe cases. It was a total breakthrough that would go on to save millions upon millions of lives. Tu's discovery is considered as important as the invention of penicillin!In 2015, after decades of being overlooked, Tu Youyou was finally awarded the Nobel Prize in Medicine. She was the first Chinese person ever to get a Nobel in science. At age 84, this humble, brilliant scientific hero finally got the recognition she deserved.What I love most about Tu Youyou's story is her incredible perseverance. She never gave up, even when it seemed hopeless. She tried every approach, thinking outside the box until she cracked the code. And she accomplished all of this whileovercoming huge barriers as a poor village woman with little formal education.Tu is living proof that you can achieve amazing things through hard work, creativity and never giving up on your dreams. She's a true inspiration to me and to young people everywhere, especially girls who face obstacles in pursuing science.Whenever I feel discouraged or want to quit on something, I think of Tu Youyou spending years soaking wormwood samples, never knowing if she'd find the answer. Her grit and brilliance gave the world an incredible gift. That's the kind of perseverance and scientific passion I aspire to. Tu Youyou is my hero!篇6Tu Youyou: The Woman Who Defeated MalariaHave you ever heard of malaria? It's this super nasty disease that's caused by tiny parasites called Plasmodium. These little critters get into your blood and make you really, really sick. Like, we're talking high fevers, chills, and feeling so weak you can barely move. For a long time, malaria was a huge problem, especially in hot, tropical places. Millions of people got it every year, and many even died from it.But then along came a hero: Tu Youyou. She's this totally amazing scientist from China who dedicated her life to finding a cure for malaria. Now, you might be thinking, "But wait, weren't there already medicines for malaria?" Yes, there were, but the problem was that the parasites were getting smarter and becoming resistant to those drugs. So Tu Youyou knew she had to find something new, something the parasites couldn't outsmart.Her search led her to an unexpected place: ancient Chinese medicine books! Tu Youyou realized that these old books might hold the key to curing malaria. After all, people had been dealing with the disease for centuries, and they must have found some remedies, right? So Tu Youyou and her team started digging through these ancient texts, looking for any mention of treatments for fever or malaria-like symptoms.And you know what? They hit the jackpot! They found an old recipe that used a plant called sweet wormwood. The recipe said to extract the plant's juices and use them to treat fever. Tu Youyou was like, "Aha! This could be it!" But here's the tricky part: the recipe was super vague and didn't give many details. It was like trying to follow a cooking recipe that just says "mix ingredients, cook, and serve."But Tu Youyou didn't give up. She and her team spent years experimenting with different methods of extracting the plant's compounds. They tried heating it, cooling it, soaking it in different solvents – you name it, they tried it. And finally, after countless failed attempts, they cracked the code!The key was to extract the compounds at a precise temperature and with a very specific solvent. When they did it just right, they ended up with a purified compound called artemisinin. And you know what? It worked like a charm against the malaria parasites! Tu Youyou had discovered a powerful new antimalarial drug, one that the parasites couldn't resist.Thanks to Tu Youyou's discovery, millions of lives have been saved from malaria.

In 1929, another far-reaching finding was made by the son of a Scottish shepherd. Before he went on holiday, biologist Alexander Fleming left a dish with bacteria in his laboratory.
“E=mc²showed how a small piece of mass could produce an unbelievable amount of energy.
Einstein then showed in his “theory of relativity” that not even time and mass are constant – they change according to our experience of them.
Edwin Hubble was about to make astronomy’s greatest breakthrough of the century.
He discovered small areas of mist which were in fact galaxies like our own, millions of light years away from us, which proved that the universe was vastly larger than had previously been thought.
Amazing discoveries were made in medicine, communications and transport, not to mention our knowledge of the world and space.
Medical advances ranged from discovering the cases of diseases under microscopes to surgical procedures replacing diseased organs with donated ones.
Although it is impossible to choose the most important discovery, it is possible to single out a few pioneers of the 20th century.
One of the 20th century’s premier scientists was Albert Einstein. In the summer of 1905, this outspoken young man was rocking his one-year-old baby when he was suddenly inspired.
During the Second World War, when Fleming’s discovery was first helping to cure people, the US Navy was looking for ways of improving the accuracy of their missiles.
Communications developed with the introduction of mobile phones and the way we correspond went from writing letters to emailing.
We started flying around the world and meanwhile, scientists figured out how to split the atom, previously thought to be the smallest particle of matter in the universe.
A few years later, penicillin was being mass-produced and helping to save the lives of millions.
ቤተ መጻሕፍቲ ባይዱ
Fleming remained modest about the amazing outcome of his discovery.
For example, we are all grateful for the microwave oven that allows us to prepare meals in minutes and we have Percy Spencer to thank.
This inventor, with 120 patents to his name, discovered microwaves when he was experimenting with radars and noticed a chocolate melting in his pocket.
These pioneers of the 20th century were dedicated to improving the quality of human life on earth, but sometimes discoveries that have affected our lives today happened by mistake.
Edwin Hubble
A young ex-lawyer, returning from the First World War, started work in California.
Using the most high-powered telescope of the time, he began the process of exploring our galaxy.
There is no doubt about it. Without the breakthroughs of these pioneers in science and technology, whether lucky or planned, the world as we know it today would have been a completely different place.
When he came back, he noticed something strange. He doublechecked and saw a kind of mould in the dish around which the bacteria had been destroyed.
This mould was in fact the earlier form of penicillin, which could be used to kill bacteria.
It measured 100 feet long by over 10 feet high and weighed over 30 tonnes.
With 18,000 tubes, thousands of circuits and 6,000 switches, it used so much energy that when it was turned on, the lights in the local town went out!
The navy turned to Eckert, an engineer, and Mauchly, a physicist, to wrestle with the problem and produce a machine to do the job.
This huge machine was the world’s first computer, but it was nothing like our computers today.
