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。

一、阅读理解(共8小题，每小题2分，共16分）AThink about the longest elevator ride that you’ve ever taken. Whether you rose five floors or 100, it probably took less than a few minutes. Now imagine riding in an elevator higher and higher as it climbs for nearly a day. When you reach the top floor, prepare for views that are really out of this world. You’ll be in space!Space elevators might sound like a crazy idea, but they’re something scientists have been working on for decades.Why would anyone want a space elevator? At the moment, riding in a capsule is the only way ordinary people can get to and from space. But those rides are very expensive — about $25 million per person per flight.Researchers are still figuring out the details about how a space elevator might work. One idea is stretching a very long cable — more than 37,000 kilometers — up to space from the earth’s equator (赤道). The location is important: Objects in space above the equator orbit the earth at the same speed that our planet turns. A weight on the end of the cable would stretch it tight. An elevator tied to the cable could use it to climb up and down.The only problem is that besides being long, this cable must also be very strong. Storms, including hurricanes might break it. One way to solve this problem is to stretchthe cable from the moon instead of from the earth. Airplanes designed to climb higher than a typical jet might take off from the earth and link up with the cable, which would be held in place by the pull of gravity from the earth. An elevator car waiting therewould then take riders the rest of the way to the moon. Fueled by solar power, theelevator could transport people and materials without much expense or effort per ride.So, when will you be taking your first space-elevator ride? Probably not for awhile.1. The first paragraph is presented by________. A. giving an example B. making a comparison C. asking questions D. analyzing causes2. Why have scientists been working on space elevators? A. To make trips to space cheaper. B. To help astronauts do research in space. C. To find a more convenient way to the moon. D. To prove an assumption which seems crazy.3. The underlined word “it” in Paragraph 4 refers to ________. A. the cable B. the equator C. an object in spaceD. a weight on the end of the cable此卷只装订不密封班级姓名准考证号考场号座位号4. Which part of a magazine may the article appear in?A. Science and technology.B. Sports.C. Literature.D. Entertainment.BWithin five years, a woolly mammoth (猛犸象)will likely be cloned, according to scientists who have just recovered well-preserved bone marrow (骨髓) in a mammoth bone.Russian scientist Siemyon Grigoriev and his colleagues are now analyzing the marrow, which they obtained from the mammoth, found in Siberian soil. Grigoriev and his team, along with colleagues from Japan, have announced that they will start a joint research project aimed at recreating the enormous mammal, which went extinct around 10,000 years ago. Mammoths used to be a common sight in North America and Eurasia. Many of our distant ancestors probably had regular face-to-face encounters with the elephant-like giants.The key to cloning the woolly mammoth is to replace the nuclei of egg cells from an elephant with those extracted from the mammoth’s cells. Doing this, according to the researchers, can result in embryos with the mammoth’s DNA. That has actually been known for a while.What have been missing are the woolly mammoth’s nuclei with undam aged genes. Scientists have been on a search for such nuclei since the late 1990s. Now it sounds like the missing genes may have been found.In the course, global warming may be responsible for the breakthrough. Warmer temperatures tied to global warming have melted ground in eastern Russia that is almost always permanently frozen. As a result, researchers have found a fair number of well-preserved frozen mammoths there, including the one that produced the bone marrow.Is it such a good idea, however, to clone animals that have long been extinct? For a while there has been some discussion of a real-life Jurassic Park setup containing such animals. Introducing these beasts into existing ecosystems could be like bringing in a potentially invasive species that would try to fill some space presently held by other animals. Even if the cloned animals were contained in special parks, there could still be a risk of spreading.So if the woolly mammoth is successfully cloned sooner rather than later, we’d probably be left with more questions and arguments than answers, at least in the short term.5. Which of the following would be the best title for the passage?A. How to clone a woolly mammothB. The woolly mammoth — an ancient speciesC. The research made by Russian and Japanese scientistsD. A woolly mammoth to be cloned6. Which of the following can be the key factor in cloning a mammoth?A. To find a living mammoth in North America or Eurasia.B. To use nuclei from a mammoth’s egg cells to replace the nuclei in an elephant’s egg cells.C. To find out when and where woolly mammoths lived on the earth.D. To find out if an cient mammoths are distant ancestors of today’s elephants.7. Which of the following best describes the writer’s attitude towards the future of cloning a mammoth?A. Uncertain.B. Indifferent.C. Positive.D. Disappointed.8. From the passage, we can learn that ________.A. some other extinct species have been cloned successfullyB. the mammoth used to be a very common speciesC. the clone of mammoths should be banned by lawD. a woolly mammoth will be successfully cloned this year二、语法填空（共10小题，每小题1.5分，共15分）Cloning has always been with us and is here to stay. It is a way of making ____1____ exact copy of another animal or plant. Cloning plants is straightforward while cloning animals is very complicated. The process of cloning is a difficult task ____2____(undertake). Many attempts to clone mammals failed. But finally the determination and patience of the scientists paid ____3____ in 1996 with a breakthrough-the cloning of Dolly the sheep.At first the fact ____4____ she seemed to develop normally was very encouraging. Then came the ____5____(disturb) news that Dolly had become seriously ill, which made cloning scientists cast down. Meanwhile, Dolly’s appearance raised a storm of ____6____(object) and had a great impact on the media and public imagination. ____7____(apparent) it became controversial. Although at present human egg cells and embryos ____8____(need)for cloning research are hard to obtain, newspapers wrote of evil leaders ____9____(hope) to clone themselves to attain their ambitions. Religious leaders also raised moral questions. Some countries reformed their legal systems and ____10____(forbid) research into human cloning, but others like China and the UK, continued to accumulate evidence of the abundant medical aid that cloning could provide.三、短文改错(共10小题，每小题1分，共10分）假定英语课上老师要求同桌之间交换修改作文, 请你修改你同桌写的以下作文。

人教版高中英语选修八unit2 Cloning

unit2 CloningⅠ.阅读理解AThere are many ways in which human cloning is expected to benefit humans.Dr Richard Seed, one of the leading supporters of humancloning technology, suggests that it may someday be possible tocompletely change the aging process because of what we learn fromcloning.Scientists believe that they may be able to treat heart attackvictims by cloning their healthy heart cells and injecting them into the areas of the heart that have been damaged. Heart disease is the number one killer in the US and several other industrialised countries.There has been a breakthrough with human stem cells. Embryonic stem cells can be grown to produce organs to repair or replace damaged ones. Skin for burn victims, brain cells for the brain damaged, hearts, lungs, and kidneys could be produced. By combining this technology with human cloning technology, it may be possible to produce needed organs for suffering people that will be free of rejection by their immune systems. Conditions such as Alzheimer’s disease, Parkinson’s disease, heart failure, and other problems can be cured if human cloning and its technology are not banned.Though current treatments for infertility (不生育) are getting a fair amount of publicity in the news, they, in terms of percentages, are not very successful. Some data shows that current infertility treatments are less than 10 percent successful. Couples go through physically and emotionally painful procedures for a small chance of having children. Many couples run out of time and money without successfully having children. Human cloning could make it possible for many more infertile couples to have children than ever before possible.语篇解读：本文作者从几个方面介绍了克隆人技术给人类带来了利益。

选修8 Unit2 Cloning

选修8 Unit2 CloningUsing Language说课稿本节课是选修8教材中第二单元语言运用部分，侧重于提高学生读、听、说的语言运用能力，同时培养学生在活动中相互学习、相互帮助的意识，发展学生英语学习的合作精神。

一、教学目标的设计1、通过阅读，让学生用材料中的句型、短语、词汇来加深对克隆技术的了解。

2、通过听力，让学生借助原有的听力基础和本课新学的知识来试谈对克隆动物的看法，即克隆的优点和不足。

3、通过说的活动，让学生进一步提高用英语来表达对克隆的认识，即克隆与生活、克隆与自我的关系。

二、文本解读第一部分：阅读材料。

通过一篇有关“克隆羊多利”的文章，讲述人类动物克隆研究，让学生通过阅读了解克隆。

首先通过阅读明确文章的观点，然后通过再次阅读让学生明白不能克隆的原因。

第二部分：听的材料。

让学生听一段关于克隆是否是对动物残忍的对话，首先进行听前预测，接着听大意，然后听细节，最后展开讨论，让学生发表自己的看法。

这项活动不但有利于提高学生的听说能力，而且能开发他们对克隆动物健康的关注及对克隆技术发展前景的再思考，具有现实意义。

第三部分：说的材料。

以“你最想克隆什么东西”问题展开，旨在发挥学生的想象力，然后通过“你想克隆一个与你一样的人吗？”这样的问题让学生各抒己见，增加学生的语言输出量，增强课堂的趣味性。

最后把这一部分作为一篇课后写作加以落实，提高学生的语言综合运用能力。

三、关于选修课的设计根据《高中英语课程标准》，选修课的设计应以课程目标和学生的需求为依据，要充分考虑学生的学习现状，既要有新内容、新发展，又不能超出学生的实际水平。

教师要引导学生主动学习，帮助他们形成以能力发展为母的学习方式，鼓励学生通过体验、实践、讨论、合作和探究等方式，发展学生的听说读写的综合语言技能。

四、课后反思对自己在课堂上未能充分调动学生的积极性而感到遗憾，课堂气氛不够热烈，主动发言的学生较少，还需更多考虑课堂指令的明确性。

Unit 2 Cloning【美文阅读】Pandas can be saved by cloning?从1998年中国科学院动物研究所首席科学家、动物克隆与受精生物学学科带头人陈大元首次正式提出克隆大熊猫到现在，整整16年过去了，陈老仍然执著于此。

然而保护大熊猫，究竟要不要通过克隆的方式呢？China has been exploring every possible means of saving giant pandas，one of the world's most endangered species，from becoming extinct，even if it means resorting to(诉诸) cloning them.Chen Dayuan，a senior scientist who specializes in cloning at the Institute of Zoology in the Chinese Academy of Sciences，introduced the idea of performing cloning techniques on giant pandas in 1998.Using initial funding of 100,000 yuan，Chen successfully produced blastocysts(胚泡) by transplanting the somatic nucleus from sample pandas into the egg cells of rabbits.The move was considered as one of the 10 biggest achievements of science and technology in 1999.It won an award of 6 million yuan and further funding of 5 million yuan for the project from the Ministry of Science and Technology.At first，two embryos were created from a surrogate mother(代母) cat who became pregnant after bei ng injected with a blastocyst，but the experiment was abandoned after the cat died.Chen and his team then experimented with surrogacy on black bears.After three years of effort，a black bear became pregnant and the shape of a fetus(胎儿) could be seen on an ultrasound scan(超声波扫描检查)．However，the research was stopped in 2005 because the fetus did not completely develop before the project's deadline.“Those who are against cloning have made their voices heard throughout the research project on cloning giant pandas.Some people believe cloning goes against nature，but it is actually a pioneering technology.If successful，it is a way to save endangered animals，”Chen said.Some scientists take a different view.“While I agree that research on cloning is meaningful，it is inappropriate to use giant pandas in this type of experiment.The number of pandas is limited and human beings have yet to master knowledge about pandas' pregnancy.Cloning would do little to save the species，”said Wang Dajun，a researcher at the School of Life Sciences，Peking University.In response，Chen said that he would continue his research.【诱思导学】1．Do you think pandas can be saved by cloning？Why?______________________________________________【答案】省略2．Why are some scientists against cloning pandas?______________________________________________【答案】Because they think cloning go against nature.Period ⅠPreviewing(教师用书独具)●教学目标本课时主要是通过学生对学案所给出的内容的学习，了解本课文中所出现的词汇，初步了解课文以及相关的背景知识，为下一堂课对课文的全面理解起到一个铺垫作用。
