⾼考英语⼀轮复习话题37克隆（Unit2Cloning）新⼈教版选修8话题37 克隆（Unit 2 Cloning）晨读背诵When the media report on cloning in the news, they are usually talking about only one type called reproductive cloning. There are different types of cloning however, and cloning technologies can be used for other purposes besides producing the genetic twin of another organism.Scientists have been cloning animals for many years. In 1952, the first animal, a tadpole, was cloned. Before the creation of Dolly, the first mammal cloned from the cell of an adult animal, clones were created from embryonic cells. Since Dolly, researchers have cloned a number of large and small animals including sheep, goats, cows, mice, pigs ,cats, rabbits, and a gaur. All these clones were created using nuclear transfer technology.汉语⼤意：当媒体报道的克隆的消息，他们通常所说的只有⼀种称为⽣殖性克隆的类型。

课时提能练(三十七)Ⅰ.阅读理解(2019·郑州质检)Eight years before his death in 1896，Alfred Nobel was surprised to read an obituary(讣告) in the local newspaper.This was a strange obituary，for it told Alfred Nobel，the man who was reading it，that he was dead.The newspaper had confused Alfred with his brother，Ludvig，who had recently died.Nobel was shocked to read that he had passed away，and he was even more annoyed by the title of his obituary：The merchant of death is dead.Alfred was a very rich and successful armaments manufacturer(武器制造商)．This incident got him thinking about his reputation.What would people think of him after his real death？Would they really say“That was a man who profited from killing？”It was this thought that led him to leave his money—a huge amount of it—for the founding of the famous Nobel prizes.His aim was for his money to be used to support the ongoing quest(追求) for excellence in the sciences and literature，and the ideal of peace.Thousands of men and women have been honored since the first awards were given out in 1901.The awards let the world know about the developments that may have a huge effect on our lives.However，the prizes are controversial sometimes.There is often protest(抗议) at the award of the Peace Prize when not everyone thinks that the awardwinners deserve the award.Even the award for literature has sometimes been criticized because the award committee often neglects important writers.The highly influential novelists James Joyce and Marcel Proust，for example，were never honored by the Swedish Academy.Still，for the most part the awards don't cause many complaints.Alfred Nobel founded the prize s to recognize those who have had“the greatest benefit to mankind”and few would disagree that most of the prizewinners—among them，Albert Einstein and Martin Luther King Jr.—have made contributions that deserve to be honored and remembered.【语篇解读】本文是一篇人物故事类记叙文，作者主要讲述了诺贝尔奖设立的来历。

well.Then，suddenly，the interviewer asks an unexpected question，“Which is more important，law or love？”Job applicants in the West increasingly find themselves asked strange questions like this.And the signs are that this is beginning to happen in China.Employers want people skilled，enthusiastic and devoted.So these are the qualities that any reasonably intelligent job applicants will try to show no matter what his or her actual feelings are.In response，employers are increasingly using questions which try and show the applicant's true personality.The question in the first paragraph comes from a test called the Keirsey Personality Sorter.It is an attempt to discover how people solve problems，rather than what they know.This is often called an aptitude test(能力倾向测验)．According to Mark Baldwin many job applicants in China are finding this type of questions difficult.When a Chinese person fills out an aptitude test he or she will think there is a right answer and they may fail because they try to guess what the examiner wants to see.This is sometimes called the prisoner's dilemma.Applicants are trying to actcleverly in their own interest.But they fail because they don't understand what the interviewer is looking for.Remember that in an aptitude test，the correct answer is always the honest answer.16．The writer wrote the passage to ________．A．give a piece of advice for job intervieweesB．tell you how to meet a job interviewerC．describe the aptitude testD．advice you how to find a job17．Why do the interviewers ask such questions?A．They want to discover what the interviewees know.B．They are curious about the answers.C．They try to discover the ability of the interviewees' solving problems.D．They just ask questions without thinking much.18．According to the writer，in an aptitude test，Chinese job applicants should ________．A．not tell the truthB．learn to tell what they really thinkC．be more enthusiasticD．try to find out what the examiner really wants to know19．From the passage we know that ________．A．job applicants are always asked such questionsB．more Chinese applicants fail to find a jobC．applicants should not act as reasonably as a prisonerD．the aptitude test is becoming popular worldwideBImagine it's 2035.You have a good job，a big family and you're about 40 years old.Welcome to your future life.Getting ready for work，you pause in front of the mirror.“Turn red，” you say.Your shirt changes from sky blue to deep red.Tiny preprogrammed electronics are rearranged in your shirt to change its color.Looking into the mirror，you find it hard to believe that you are 40.You look much younger.With amazing advances in medicine，people in your generation may live to be 150 years old.You're not even middleaged.As you go into the kitchen and prepare to pour your breakfast cereal(谷类食物) into a bowl，you hear: “To lose weight，you shouldn't eat that，” from your shoes.They read the tiny electronic code on the cereal box to find out the nutrition details.You decide to listen to your shoes.“Kitchen，what can I have for breakfast？” A list of possible foods appear on the counter as kitchen checks its food supplies.“Ready for your trip to space.” You ask your son and daughter.Before the 21st century only specially trained astronauts went into space—and very few of them.Today anyone can go to space for day trips or longer vacation.Your best friend even works in space.Handing your children three strawberries each，you add，“The doctor said you need these for space travel.” Thanks to medical advice，vaccination shots(疫苗注射) are a thing of the past.Ordinary foods contain specific vaccines.With the berries in their mouths，the kids head for the front door.It's time for you to go to work.Your car checks your fingerprints and unlocks the doors.“My office.Autopilot.” You comman d. Your car drives itself down the road and moves smoothly into traffic on the highway.You sit back and unroll your enewspaper.The latest news downloads and fills the viewer.Looking through the pages，you watch the news as video films rather than read it.20．What changes the color of your shirt?A．The mirror.B．The shirt itself.C．The counter.D．The medicine.21．How do the shoes know that you shouldn't eat breakfast cereal?A．By pouring breakfast cereal into a bowl.B．By listening to the doctor's advice.C．By testing the food supplies in the kitchen.D．By checking the nutrition details of the food.22．How is the text organized?A．In order of time.B．In order of character.C．In order of preference.D．In order of importance.Ⅲ.短文填词Mr Smith offers us some advice on how to write a good composition, which 23.i________ the following steps.

That's the conclusion of a recent study from South Africa's southern coast.There， in a cave lying above the sea， researchers from Arizona State University have found evidence that humans were behaving in surprisingly complex ways as early as 164,000 years ago. Our species， Homo sapiens，appeared an estimated 200,000 years ago.The cave held three important clues about the behavior of these Stone Age people.First， the researchers found the remains of all kinds of shellfish. The people who lived in the cave probably collected these creatures from rockyshores and tide pools and brought them to the cave to eat.The researchers propose the early Africans moved to the South African coast between 195,000 and 130,000 years ago. Around that time， the climate inland turned relatively cold and dry. Therefore， there were fewer plants and animals to eat away from the coast.When these ancient people moved to the coast， they probably experienced a major cultural shift， the researchers suspect. That's because observations of modern hunter－gatherer societies suggest that men are more likely to hunt for big animals when people live inland. On the coast， women play a more important role in providing food by gathering plants and shellfish.As for the second clue， the researchers unearthed 57 pieces of reddish pigment(颜料). The researchers think that the cave habitants used the paint for coloring their bodies or for other ceremonies. Symbolic behavior is a clearly human feature.Finally， the search discovered over 1,800 stone tools， including well －crafted blades(刀片). These blades came in various sizes. The smallest were just less than a half－inch wide. Ancient people may have attached these blades to the end of a stick to make spears or other tools.16．What is the passage mainly about？A．Ancient cave behavior.B．New evidence of ancient life.C．The history of human beings.D．Human behavior's development.17．The early Africans moved to the South African coast with the main purpose of ________.A．avoiding badly cold and dry weatherB．seeking the cultural developmentC．seeking enough food to live onD．living a newer and better life18．According to the passage， the cave habitants________.A．knew how to use colors for decorationB．made a living largely by hunting animalsC．only could made tools with rough bladesD．could hunt for fish in the sea with ships19．After the early Africans moved to the coast， what probably happened to their culture？A．Women's role was as important as men's role in families.B．They were no longer used to living inlands but living on the coast.C．Men's role was more important than women's role in earning food.D．Women's role was more important than men's role in earning food.20．The new discoveries in the cave should support the theory that ________.A．modern human behavior developed smoothly fast from the ancient time B．modern human behavior developed slowly from the ancient timeC．South Africa is the birthplace of the earliest human beings in the worldD．modern human behavior is largely the same as ancient human behaviorⅢ.阅读表达阅读下面短文并回答问题，然后将答案写到相应的横线上(请注意问题后的词数要求)。

课时达标(三十七) Unit 2 CloningⅠAZhong and Hua Hua, using the same technique that gave to Dolly the sheep. These monkeys are not actually the first primates(灵长类) to be cloned. Another one named Tetra was produced in the late 1990s by embryo(胚胎) splitting, the division of an early－stage embryo into two or four separate cells to make clones. By contrast, they were each made by replacing an egg cell nucleus(细胞核) with DNA from a differentiated body cell. This Dolly method, known as somatic cell nuclear transfer(SCNT), can create more clones and allows researchers greater control over the edits they make to the DNA.Success came from adopting several new techniques. These included a new type of microscopy to better view the cells during handling or using several materials that encourage cell reprogramming, which hadn't been tried before on primates. Still, the research process proved difficult, and many attempts by the team failed. Just two healthy baby monkeys born from more than 60 tested mothers. This leads to many researchers' pouring cold water on the idea that the team's results bring scientists closer to cloning humans. They thought this work is not a stepping stone to establishing methods for obtaining live born human clones. Instead, this clearly remains a very foolish thing to attempt, it would be far too inefficient, far too unsafe, and it is also pointless.But the scientists involved emphasize that this is not their goal. There is now no barrier for cloning primate species. Thus cloning humans is closer to reality. However, their research purpose is entirely for producing non－human primate models for human diseases; they absolutely have no intention, and the society will not permit this work to be extended to humans. Despite limitations, they treat this breakthrough as a novel model system for scientists studying human biology and disease.语篇导读中国科学家利用SCNT技术克隆出了两只猴子，文章介绍了相关信息并讨论了这种克隆实验的影响。

课时作业37Ⅰ.阅读理解(2019·烟台一中高三适应性考试)China became the first country to clone a monkey using nonreproductive cells, reducing the need to breed lab monkeys and paving the way for more accurate, effective and affordable animal tests for new drugs, scientists said on Thursday.By December, the Institute of Neuroscience of the Chinese Academy of Sciences had created two clone macaques(猕猴) named“Zhong Zhong” and “Hua Hua” by nuclear transferring of somatic cells(体细胞)—any cell in the organism other than reproductive cells.Tetra, a monkey born in 1999, is the world's first cloned monkey, but it was done by using a simpler method called embryo splitting(胚胎分割); but it could only generate four cloned offspring at a time and cannot be genetically changed to suit the experimental need.Cloning a monkey using somatic cells has been a worldclass challenge because it is a primate(灵长类) that shares its genetic makeup, and therefore all of its complexity, with humans.For drug and other lab tests, scientists have to purchase monkeys from all over the world, which is costly and bad for the environment, and produces inaccurate results because each monkey might have different genes.By cloning monkey using somatic cells, we can massively cultivate large numbers of genetically identical offspring in a short amount of time, and we can even change their genes to suit our needs. This can save time, cut down experiment costs, and produce more accurate results, leading to more effective medicine.Sun Qiang, director of the nonhuman primate research facility at the institute, said most of the drug trials are currently done on lab mice. However, drugs that work on mice might not work or even have severe side effects on humans because the two species are so different.“Monkeys and humans are both primates, so they are much closely related and testing on monkeys is supposed to be as effective as testing on humans，”he said. This is especially useful in testing drugs for neural (神经的) diseases such as Parkinson's disease, metabolic syndrome (代谢综合征) and immune system diseases, and tumors, he added.“This achievement will help China lead the world research in the international science projects related to neural mapping of primate brains，”he said. “However, bio labs from the United States, Japan, and European countries are also very capable, and they will quickly catch up with China after the monkey cloning technology ismade public，” Sun added.“This means we have to innovate continuously and work extra hard this year to stay ahead，” he said.本文是一篇科普类说明文。
