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。

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 rocky shores 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.Fin ally , the search discovered over 1,800 stone tools in clud ing 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 evidenee of ancient life.C. The history of human beings.D . Human behavior's development.17. The early Africa ns moved to the South Africa n coast with the main purpose of _______ .A . avoiding badly cold and dry weatherB . seeking the cultural developmentC . seek ingeno ugh food to live on D . livi ng a n ewer and better life18 . Accord ing to the passage, the cave habitants _______ .A . knew how to use colors for decorati onB . made a liv ing largely by hunting ani malsC . only could made tools with rough bladesD . could hunt for fish in the sea with ships19 . After the early Africa ns moved to the coast , what probably happe ned to their culture ?A . Women's role was as important as men's role in families.B . They were no Ion ger used to livi ng inlands but liv ing on the coast.C . Men's role was more importa nt tha n wome n's role in earning food.D . Wome n's role was more importa nt tha n 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 timeB . moder n huma n behavior developed slowly from the an cie nt timeC . South Africa is the birthplace of the earliest huma n beings in the worldD . moder n huma n behavior is largely the same as ancient huma n behavior川.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）。
